The segment is unilaterally connected with the wall in a single piece. A free longitudinal end section (122) of the segment partially protrudes inwardly into the sleeve. A small inner diameter, which is formed by embossings running interior to the wall, is greater than a small inner diameter, which is formed by the end section of the segment.

Description

The invention relates to an electrical outer conductor sleeve, in particular for an electrical angle connector, in the automotive field.

Coaxial cable form z. As in analog image transmission or digital communication in computer networks, the predominant type of wiring, as they are compared with conventional cables, much less susceptible to interference and can transport much more data. In particular, in the automotive field coaxial cables are increasingly used to z. B. to establish an electrical connection of the electrical system with a radio, a GPS device or mobile devices. Furthermore, coaxial cables and coaxial connectors find a wide application in telecommunications, where they are used for a wide variety of connections in the base stations of mobile communication networks.

Coaxial connectors are used to electrically couple coaxial cables or to connect a coaxial cable to an electrical or electronic component or assembly. A coaxial cable essentially comprises two concentric conductors (inner and outer conductors), which are electrically insulated from each other by a dielectric. In a coaxial connector, an inner conductor contact of the connector with the inner conductor of the coaxial cable is electrically connected and represents the extension of the signal transmission path. The coaxial connector further comprises an outer conductor contact, which is electrically connected to the outer cable conductor, usually a wire mesh of copper, and a connection to the Represents ground path.

A special case of the coaxial connector is the elbow connector, in which a mating with a mating connector does not extend in the direction of the cable longitudinal axis, but transverse to it, usually at a right angle. Such angle connectors are often used when a coaxial cable with a z. B. on a circuit board firmly mounted mating connector to be connected.

The US 4,426,127 discloses a coaxial electrical connection with an inner contact spring of a socket, wherein on the contact spring a plurality of contact blades projecting freely inwardly into a housing of the socket.

The US 5 562 506 discloses a coaxial cable electrical connector having a socket whose contact spring for an outer conductor of a coaxial cable is seated on a housing of the socket. The contact spring has free from the contact spring protruding slats, which are received in the mounted socket in housing slots.

The US 3,966,292 discloses a coaxial electrical connector with a socket on the outer periphery of a plurality of contact blades projecting freely. The contact blades extend substantially in an axial direction of the sleeve and are electrically connected to the outer conductor of a coaxial cable. The contact blades are used for electrical contacting of an external contact of a plug, wherein the external contact of the plug is connected to the outer conductor of a second coaxial cable. As a result, an internal contact point of the inner conductor of the two coaxial cable is shielded.

The problem with free from the socket projecting contact blades that this no protection against damage, eg. B. during transport and handling, and against overstretching, z. B. when mating with a mating connector, have. Furthermore, the contact blades are sharp-edged due to their production (punching from a metal sheet), which in particular in the automotive sector unwanted damage caused by the freely accessible slats, z. B. when placing the jack on vehicle seats, may arise. This can cause small cracks, which can lead to optical impairments later, especially on leather seats. In addition, it happens again and again that threads are pulled out by the barbed contact blades made of fabric covers.

See also the explanations below to Fig. 1 below, in which also the prior art is explained in more detail.

The DE 20 2004 004 829 U1 , the U.S. 4,880,396 , the US 5 533 914 and the US 6,129,585 disclose each straight-line slotted contact springs for sockets, wherein in the wall of the contact spring contact blades are provided, which are each formed by two adjacent slots. The contact blades are formed with their respective longitudinal ends materially integral with the contact spring.

The US 5 088 942 discloses a socket for electrical connection of two single-core electrical terminals, with a seamless contact body having a substantially cylindrical cavity and accessible on one side for a plug. Within the contact body is an open at its periphery socket spring for electrically contacting the plug. The female spring has contact arms in a central portion projecting inwardly of the female spring and electrically contacting the male in the inserted state.

The EP 0 236 824 A2 and the DE 86 30 393 U1 disclose contact springs for a contact sleeve of a coaxial connector, wherein the respective contact spring of an approximately U-shaped through-hole in a wall the contact sleeve is defined and lies behind a web of the wall of the contact sleeve.

The DE 103 15 042 A1 discloses a coaxial connector having an outer conductor terminal having two diametrically opposed, resilient contact portions projecting inwardly into the outer conductor terminal. In this case, the contact parts are provided in a wall of the outer conductor connection, are defined by a U-shaped through-passage in the wall and are located behind a web of the wall of the outer conductor connection.

In the following, a coaxial coaxial connector is understood to be a coaxial socket and / or a coaxial connector. The same applies to a subassembly of the coaxial jack and / or the coaxial connector, the analog coaxial connector subassembly, z. B. outer conductor sleeve, is called.

It is an object of the invention to realize an improved electrical outer conductor sleeve for a coaxial connector. In particular, the electrical outer conductor sleeve should be protected against damage and overstretching of contact blades and realize a secure centering of an outer conductor of a mating connector. Furthermore, the outer conductor sleeve when placing and re-taking, z. B. on fabric or leather covers, leave no damage.

The object of the invention is achieved by means of an electrical outer conductor sleeve for an electrical coaxial jack or an electrical coaxial connector, wherein the circumferentially closed outer conductor sleeve distributed on its circumference spring contact blades (hereinafter called spring blades) arranged. The spring blades are substantially in an axial direction of a contact sleeve of the outer conductor sleeve to the outside, and are protected between a ring of the outer conductor sleeve and the contact sleeve of the outer conductor sleeve arranged; wherein the ring is also supported on the contact sleeve. The respective spring blades of the outer conductor sleeve are provided via a continuous passage slot with respect to a cage of the outer conductor sleeve, wherein the passage slot has at least one curvature or curve. The passage slot gives the spring blade essentially its characteristic outer contour in the directions of the wall of the outer conductor sleeve.

The following statements relate only to an outer conductor sleeve of an electrical coaxial socket subassembly, wherein in the electrical coaxial socket subassembly preferably against an insertion direction of an electrical mating connector, an inner conductor socket contact can be inserted and thereby results in a coaxial socket. However, it is also possible to insert an inner conductor pin contact into the coaxial socket subassembly, resulting in an electrical coaxial connector. It should be expressly noted that a coaxial socket subassembly should also be included with a coaxial socket subassembly. Further, the coaxial socket is referred to as a socket and the coaxial plug as a plug.

According to the invention, the free end of the mating connector externally contacting spring blades is located within the wall of the outer conductor sleeve, so that the spring blades are protected on the one hand against damage and overstretching, and the spring blades on the other hand no longer cause damage by scratching surfaces or stringing fabric cladding. Preferably, the spring blades are at least partially bent into the interior of the outer conductor sleeve, so that no area of the spring blades protrudes more from a lateral surface of a finished socket to the outside.

By the superior in the insertion direction of a mating connector ring on the outer conductor sleeve according to the invention results a much more robust structure. As a result, in a socket subassembly, a finished socket or assembly with such a socket at a delivery no surrounding housing must be provided. This reduces the cost of the corresponding components.

In a preferred embodiment of the invention, the ring is supported by lamellae on the contact sleeve of the outer conductor sleeve, wherein the lamellae extend substantially in the axial direction of the outer conductor sleeve. By providing mutually parallel with respect to the axial direction of the outer conductor sleeve slats and spring blades, the electrical socket is simple and can be punched out of a sheet and bent together.

Here, the respective spring blade is arranged at a distance from its two radially directly adjacent lamellae and with respect to the ring via the passage slot. The passage slot forms an outer boundary for the spring blade and the blade, which are both materially connected in one piece with the contact sleeve of the outer conductor sleeve. The spring blade is connected only on one side with the contact sleeve.

The lamellae holding the ring are, in contrast to the spring lamellae, materially connected in one piece at their two longitudinal ends to the outer conductor sleeve. A longitudinal end is materially integral with the ring and this opposite longitudinal end is formed materially integral with the contact sleeve. In this case, a single passage slot bounds the respective lamella on a longitudinal side or a transverse end. According to the invention, two rectilinear sections of a single passage slot are connected to each other via the curve, the curvature partially confining the ring within the outer conductor sleeve. The two rectilinear sections limit two radially directly adjacent lamellae to the respective spring lamella.

Preferably, the electrical outer conductor sleeve has a plurality of spring blades and a plurality of blades, preferably four in each case. In this case, a single passage slot in each case defines a single spring plate completely and the lamellae or the ring parallel to it in part. This allows a simple structure, which - as stated above - much more robust than an electrical outer conductor sleeve according to the prior art. As a result, an outer conductor sleeve essentially in two operations - punching and subsequent bending - are produced.

In a preferred embodiment of the invention, the ring has a plurality of inwardly facing embossments or projections, which serve to center an outer surface of the mating connector. These embossments can also be provided exclusively on the lamellae or in each case a transition region between the ring and a lamella.

In a preferred embodiment of the invention, the spring blades also each have an inwardly projecting into the outer conductor sleeve embossing or a projection. These embossings are used for electrical contacting of the outside of the mating connector. Here, the embossments are arranged in an insertion direction of the mating connector behind the imprints of the ring or the slats.

In a preferred embodiment of the invention, a circle formed by the embossments of the ring or lamellae is larger in diameter than the circle formed by the embossments of the spring lamellae which is concentric with the former. Furthermore, a circle formed by the free ends of the spring lamellae is preferably larger in diameter than the circle formed by the embossings of the ring or the lamellae, these two circles likewise being arranged concentrically with one another. This ensures that the spring blades can not be damaged or overstretched when inserting the mating connector. This is particularly important for electrical sockets that are subject to a variety of mating cycles.

In a preferred embodiment of the invention, the outer conductor sleeve is held together by a laser welding after punching out and bending out of the metal sheet. Preferably, only a single laser welding point is located at an interface (stop) of the outer conductor sleeve. Preferably, the welding point is provided in the vicinity of the ring of the outer conductor sleeve, so that it can not expand when inserting the mating connector.

Further, the invention relates to an electrical receptacle having an electrical receptacle subassembly, the receptacle subassembly having an inner conductor female contact, and / or an electrical plug having an electrical plug subassembly, the electrical plug subassembly having an inner conductor pin contact , The electrical socket and / or the electrical connector can be designed as angle or angle plug.

Further embodiments of the invention will become apparent from the remaining dependent claims.

1 and 2 show a three-dimensional front and a three-dimensional rear view of an external contact spring 10 and an outer conductor sleeve 10 for an electrical socket according to the prior art. The outer conductor sleeve 10 essentially has two sections. The first, front portion is formed with spring blades 120, which serve for electrical contacting of an outer side of a mating connector. The mating connector is inserted in a plug-in direction S _G in the outer conductor sleeve 10 and advanced to a central portion of the outer conductor sleeve 10. The second section of the outer conductor sleeve 10 has a contact sleeve 150 or a contact box 150, by means of which the outer conductor sleeve 10 can be secured in the electrical socket.

As can be clearly seen in FIGS. 1 and 2, the spring blades 120 protrude freely from the contact box 150 and thereby extend essentially in an axial direction A of the outer conductor sleeve 10. Here, the spring blades 120 are materially integral with the contact sleeve 150 on one side or the outer conductor sleeve 10 is connected. As a result, the spring blades 120 are each movable substantially in a direction perpendicular to the axial direction A. The spring blades 120 are easily accessible from the outside in the outer conductor sleeve 10, and under unfavorable circumstances, eg. For example Transport, handling a mating connector or improper use of the electrical socket, the spring blades 120 may be damaged or overstretched, which can lead to a useless electrical socket. Furthermore, the spring blades 120 are due to the production of burrs or sharp edges and can leave damage to the deposit on a surface or tend when removing a fabric-coated surface to pull threads from the fabric.

According to the invention, this is avoided by the fact that the spring blades 120 connected on one side to the contact sleeve 150 are provided protected within the outer conductor sleeve 10. This is explained in more detail below with reference to two exemplary embodiments, wherein FIGS. 3 to 18 illustrate the first embodiment of the outer conductor sleeve 10 according to the invention and FIGS. 19 to 30 represent the second embodiment of the outer conductor sleeve 10 according to the invention.

2 and 3 each show a three-dimensional representation of an electrical socket subassembly 1 for an electrical socket in which a rear portion is omitted. In this rearward portion of the female subassembly 1, an inner conductor female contact or an inner conductor male contact (then called an electrical connector, sao) is plugged into the complete female connector. Preferably, the female subassembly 1 is manufactured and sold separately. A final assembly of the female sub-assembly 1 (also called bush subassembly) to complete jack takes place only at a customer, since depending on the application of different lengths coaxial cable with the inner conductor socket contact firmly and preferably permanently connected, on the one hand a high fatigue strength and to ensure a good electrical connection. FIGS. 5 and 6 each show a side view of the electrical socket subassembly 1, wherein FIG. 5 depicts a centrally sectioned view.

The socket subassembly 1 essentially comprises a housing 200, a receptacle 210 inserted into the housing 200 and the outer conductor sleeve 10 accommodated between receptacle 210 and housing 200. The electrical socket subassembly 1 is designed as an angle plug connection, in which a cable to be contacted by the socket (not shown), in particular a coaxial cable, is substantially perpendicular to the plugging direction of the socket (counter to the plugging direction S _G of the mating plug) in the socket subassembly 1 is included. Projections which protrude radially inwards on the receptacle 210 radially outward and / or on the housing 200 engage in the outer conductor sleeve 10 in through-passages 152 (see Figures 7 and 8) such that the outer conductor sleeve 10 with its contact sleeve 150 between the receptacle 210 and the housing 200 is received tightly. In particular, when the housing 200 of the female subassembly 1 is completed with its rear part, it is no longer possible to pull the outer conductor sleeve 10 from the electrical socket subassembly 1, as this, the receptacle 210 against the insertion direction S _G of the mating connector from the Housing 200 would have to be pulled, which is not possible due to projections 212 on the receptacle 210, which rest inside the housing 200. An assembly of the outer conductor sleeve 10 in the housing 200 and on the receptacle 210 is facilitated by a slot within the outer conductor sleeve 10, which is due to the manufacturing (sau) in the outer conductor sleeve 10 and the outer conductor sleeve 10 in the contact sleeve 150 provides a certain elasticity, the in the assembled state of the outer conductor sleeve 10 in the socket subassembly is no longer available. Within the receptacle 210 is to be contacted by the mating connector, actual inner conductor female contact, which is electrically connected to a conductor of the cable, preferably the inner conductor of a coaxial cable.

The outer conductor sleeve 10 (see, in particular, FIGS. 7 to 18 for the first embodiment and FIGS. 19 to 30 for the second embodiment) essentially has a hollow-cylindrical, cage-like configuration, wherein the outer conductor sleeve 10 substantially in three into one Axial direction A of the outer conductor sleeve 10 is divided sections extending. Namely - viewed in the insertion direction S _{G of} the mating connector - integral with the outer conductor sleeve 10 front ring portion 130, an adjoining, with the outer conductor sleeve 10 integral fin portion 120, 140, wherein the fins 120, 140 substantially in the axial direction A of the outer conductor sleeve 10, and with the outer conductor sleeve 10 integral sleeve portion 150, by means of which the outer conductor sleeve 10 in the electrical socket subassembly 1 can be fixed (see above). These three sections are all materially connected to each other in one piece and form an essentially rotationally symmetrical wall 100 of the outer conductor sleeve 10.

The outer conductor sleeve 10 forms an outer contour or an outer region of the bushing subassembly 1 or the bushing in the bushing subassembly 1 or in the later bush in the intended use and is not provided within an additional bushing or casing, for example the outer conductor bushing 10 holds together.

The outer conductor sleeve 10 is closed on at least one circumference (see below (welding point 170)). Ie. There is at least one path over the entire circumference of the outer conductor sleeve 10, which is not open at a stop 102 of the wall 100 of the outer conductor sleeve 10. Preferably, this closed circumferential path is located in the vicinity of the ring section 130. In one embodiment, the outer conductor sleeve 10 may be closed on the stop 102 of the wall 100 in sections or even over the entire stop 102.

Starting from the hollow-cylindrical contact sleeve 150, a plurality of lamellas 120, 140 extend in the axial direction A of the outer conductor sleeve 10, counter to the insertion direction S _{G of} the mating connector. The lamellas 120, 140 are distinguished into spring lamellae 120 connected on one side and lamellae 140 connected on both sides. The unilaterally connected spring blades 120 have a free end 126 and serve to make electrical contact with the outside of the mating connector; the two-sided tailed slats 140 are each integrally formed with a ring 130 with its opposite end of the contact sleeve 150. D. h., The one-sided tailed spring blades 120 are fixedly connected only with a longitudinal end of the outer conductor sleeve 10, whereas the two-sided tailed blades 140 are firmly connected with their two longitudinal ends in the outer conductor sleeve 10. The spring blades 120 and the blades 140 are arranged in the circumferential direction around the outer conductor sleeve 10 regularly and alternately, and are formed substantially strip-shaped.

In the transition region of the contact sleeve 150 and the lamella 120 growing therefrom, the lamellae 120, 140 rise radially from the curved jacket of the contact sleeve 150 to the outside and then turn into a sleeve-shaped (hollow cylindrical) section.

The spring blades 120 are spherically formed at their free longitudinal end portion 122 with an embossing 144 or an inside of the outer conductor sleeve 10 projection o. Ä., By means of which they electrically contact the outside of the mating connector in the mated state with the mating connector (see below).

In the transition region of lamellae 140 and ring 130, the lamellae 140 and / or the ring 130 are also crowned with an embossing 134, 144 or a projection projecting into the outer conductor sleeve 10. In another embodiment In the first embodiment of the invention, the embossing 144 of the lamella 140 extends in the radial direction over the entire width of the respective lamella 140. Likewise, the embossing 124 of the spring lamella 120 preferably extends radially over the lobes entire width of the spring blade 120th

The free sides of the spring blade 120 are provided at a distance from the rest of the outer conductor sleeve 10. In this case, both longitudinal sides of the spring blade 120 are spaced apart with respect to two directly adjacent blades 140, and the free end of the spring blade 120 is provided at a distance with respect to the ring 130. These distances form within the outer conductor sleeve 10 a continuous non-linearly extending passage slot 110, which has approximately U-shaped course in both embodiments. However, it is also another course of the passage slot 110, such as. B. an approximately V- or H-shaped, possible.

As can be seen in particular in the sectional views of FIGS. 10 to 13 and FIGS. 22 to 25, all spring lamellae 120 of the outer conductor sleeve 10 are provided at least partially inside in the outer conductor sleeve 10. A large part of the overall dimension of the respective spring blade 120 is located within a respective outer diameter of the outer conductor sleeve 10. This can be clearly seen in particular in the sectional views CC (FIGS. 12 and 24) and DD (FIGS. 13 and 25). Also clearly visible in these figures, is that the respective embossings 124 of the spring blades 120 - seen in the insertion direction S _G - behind the embossments 134, 144 of the ring 130 and the fins 140 are 140.

The embossings 134, 144 serve to center the outside of the mating connector when inserting the mating connector in the electrical socket. Only when advancing the mating connector the actual electrical contact points of the outer conductor sleeve 10, namely the embossments 124 of the spring blades 120 are contacted and thus electrically contacted. So that the mating plug to be inserted into the electrical socket presses the spring blades 120 radially outward and does not overstretch or collapse, the respective free ends 126 or their directly downstream longitudinal end regions (including their free ends 126) of the spring blades 120 are bent radially outward.

Preferably, a circle formed by the free ends 126 of the spring blades 120 is larger in diameter than a circle formed by the embossments 134, 144 of the cage. These two circles are substantially coaxial with respect to the axial direction A of the outer contact spring 10. This is shown in the cut rear views EE (Figs. 15 and 27) and FF (Figs. 17 and 29), where I _{144 is} the inner diameter of the Embossments 144 of the fins 140 formed, inscribed in the outer conductor sleeve 10 circle is illustrated. The inner diameter I ₁₂₆ is the diameter of the circle formed by the free ends 126 of the spring blades 120. In this case, I _{126 is} greater than I ₁₄₄ , which ensures that the mating connector after centering by the embossments 134, 144, the spring blades 120 presses radially apart and these can not overstretch or damage. The same applies to the inner diameter I ₁₃₄ (see below), which is formed by a circle defined by the embossings 134 on the ring 130.

The production of the contact spring 10 according to the invention takes place essentially in two production steps. First, a blank extending in a plane of the outer conductor sleeve 10 is punched from a suitable, thin sheet and then bent in the second step to the round configuration. A profiling of the sheet or the wall 100 can take place before or during the stamping or before the round bending of the outer conductor sleeve 10. After collapsing the Outer conductor sleeve 10 is laser welded to the resulting stop 102. This is done by means of at least one spot weld 170 which is provided in the vicinity of the ring 130 (see the three-dimensional illustrations obliquely from the rear in FIGS. Here, the first embodiment of the invention has a welding point 170 on the ring 130 and a further welding point 170 on a blade 140, whereas the second embodiment of the invention shows only a single spot weld 170 in the insertion direction S _G behind a stamping 134, 144. In the area of the contact sleeve 150 or a region of the lamellae 140 adjacent to the contact sleeve 150, the stop 102 is preferably not welded in order to ensure a certain flexibility for mounting the outer conductor sleeve 10 on the receptacle 210 or in the housing 200. Until after the laser welding, the outer conductor sleeve 10 hangs on a carrier 160, which is separated before mounting the outer conductor sleeve 10 in the socket subassembly 1.

The second embodiment of the invention differs essentially from the first in that the embossments 144 of the lamellae 140 of the first embodiment no longer extend over the entire radial extent of a single lamella 140, but by a smaller embossment 134 on the ring 130 and / or embossing 144 are replaced in the blade 140. In the illustrated embodiment, the embossing 134, 144 extends in the transition region from blade 140 to the ring 130. Here, the embossment 134, 144 is provided centrally with respect to the longitudinal extent of the blade 140. In this embodiment, two directly adjacent embossments 144 may be provided on the inside of the lamella 140.

In both embodiments, a plurality of spring blades 120 and a plurality of blades 140 are preferably formed in each case. Here, the number of spring blades 120 is equal to the number of blades 140. There are at least one spring blade 120 and a blade 140 within the Outer conductor sleeve 10. Preferably, however, an even number of spring blades 120 and blades 140, wherein preferably four of each are provided.

The fins 140 form a cage for the slats 120, between which they are arranged protected. Preferably, the fins 140 are free of burrs at least on the outside. The ring 130, which is a front boundary of the cage or part of it, prevents damage to the faulty paths; In this case, there is a collision with the rigid ring, if a mutual misalignment is too large.
