Abstract

The system contains module insert frames (1) which accept contact modules for insertion into plug connector housings. An insert frame has a frame body of two side wall parts (4,5) and two head parts (8,9), which lie parallel to and opposite each other and form an opening (3) for a contact module, which is fixed by holders on the wall parts. Guides on the head parts have male (10) and female (11) guide elements. Safety contact devices attached to the head parts are formed by one of the guide elements, which is joined to the frame body in one piece, and a single safety contact spring (20) which is attached to the other guide element.

Description

The invention relates to module insertion frames for receiving contact modules for insertion in connector housings, with a frame body made up of two cheek parts and two head pieces, which are mutually opposite and form a receiving opening for the contact modules, with holding means on the cheek parts, of which the contact modules are fixed and are held, with guide means on the head pieces, which comprise a positive / male guide element on the one hand and a negative / female guide element on the other hand, and with protective contact means which are formed on the head pieces. The invention further relates to contact modules with at least one pin contact or at least one socket contact for insertion into such module insertion frames. The invention further relates to a connector combination comprising two housings, one of which accommodates a module insert frame with at least one pin contact module and the other a module insert frame with at least one socket contact module.

Connector housings with die-cast module insert frames and with contact modules of the type mentioned inserted therein are known in different designs. One of the connector housings, usually the housing for receiving a module insert frame for socket contact modules, is used for attachment to a control cabinet wall or to a machine housing to which it is screwed on, while the second connector housing, i.e. the one for receiving a module insert frame for pin contact modules, can be freely assembled with this and if necessary via a cable serves the connection of a measuring or testing device or permanently establishes the connection with an external control or regulating unit. The insert frames used usually differ in terms of different design components. Firstly, these are the holding means which are adapted to the respective plug contact modules and which are individually designed for the two different types of plug contact modules; on the other hand, the two insertion frames differ from one another with regard to their mutual engagement. Ultimately, the protective contact elements on the two insert frames are designed differently in pairs as screw-on tabs at both ends.

Proceeding from this, it is the object of the present invention to provide insertion frames and contact modules which have a simplified structure and with which the number of parts and designs to be kept available can be reduced with variable adaptability to the practical application.

One solution consists in module insertion frames, which are characterized in that the protective contact means are formed by one of the guide elements themselves, which is integrally connected to the frame body, and a single protective contact spring, which is fastened to the other of the guide elements. With the design of such module insertion frames, it is possible to standardize the different frame types, regardless of how many different frame sizes are considered necessary. This results in logistical advantages with regard to delivery and warehousing, but first and foremost the essential advantage for the manufacturer that only one mold for module insert frames has to be produced for each connector combination. By restricting it to a protective contact spring only assembly time for the frames is also reduced. The frames are screwed into the respective connector housing in the usual way.

The summarized protective contact and guide means, which are designed "on the envelope" on the frame body, have on one head piece of rib parts and on the other head piece a block element with a slot, which interlock when making a plug connection between two housings, that is, the rib part on one frame engages in the slot of the block element on the other frame and vice versa. Here, the protective contact means comprise a single contact spring element which comes into conductive contact with the other frame when a plug connection is made between two housings. In particular, this contact spring element is U-shaped with legs pointing in the plug connection direction and is fixed with a cross leg in a bottom recess of the slot mentioned above. The legs of the contact spring element are curved in such a way that when a plug connection is made between two housings, these legs are clamped between the walls of the slot and the flanks of the rib parts of the module insertion frame.

According to a further solution, it is provided that the holding means for fixing the contact modules comprise guide pockets in the cheeks and that windows are formed in the guide pockets, which are delimited by outer webs running transversely to the plug connection direction. Hereby, stop and flange surfaces within the receiving opening are dispensed with, so that the design of the frames is considerably simplified and their weight is reduced. The windows allow improved engagement of the contact modules within the cheek surfaces. Furthermore, the holding means for fixing the contact modules preferably comprise stop edges lying on the connector side.

In an advantageous embodiment it is provided that the holding means for fixing plug contact modules and socket contact modules are identical to one another, i. H. these holding means are completely identical both in terms of their spacing from one another and in their position with respect to the respective plug connection levels, so that the frame construction becomes correspondingly simpler and less complicated. The idea addressed here of course requires a corresponding design of the contact modules provided for the module insertion frames. The holding means in the frame and the corresponding means on the contact modules are preferably so differentiated that only a single, unambiguous relative insertion position between the frame and the modules is possible, in that the holding means lying opposite one another in each case differ from one another.

In a further embodiment, it is provided that a plurality of pairs of opposing holding means for fixing a plug-in contact module are designed along the extent of the frame. In this way, plug-in contact modules can be used which only occupy a partial length of the frame, so that a plurality of plug-in contact modules can be inserted into a frame. This enables a variation in the fitting of the frames with plug-in contact modules. This enables a plug connection to be made with an individual combination of different contact modules. If only a small number of connection contacts are required, a subset of contact modules can be used in a larger frame to make them cheaper. This further reduces the requirements for warehousing and logistics, and in particular with regard to the variety of tools.

In a favorable embodiment, the receiving openings from the cable connection side in the plug connection direction are made without undercuts. This enables the installation of the plug contact modules from the cable connection side in the frame, with the possibility of that the individual plug-in contact modules can be wired outside the frame and then inserted into the frame from the cable connection side and fixed in this.

In adaptation to this configuration, the pin contact modules and the socket contact modules in the area of a frame insertion section are identical to one another and preferably comprise elastic elements thereon for producing snap-in connections to the frames. It is a significant advantage that any screw connections between the module insert frame and the contact modules can be dispensed with.

In adaptation to the above-mentioned configurations of the frames, opposite guide bases are formed in pairs on the contact modules for engagement in the guide pockets of the frames. Here, elastic tongues articulated on one side are furthermore arranged on the guide bases, which are provided with latching means which can engage in holding means on the frame. These locking means are designed in particular in the form of transverse grooves on the elastic tongues, which can lock with the window webs of the frames, which are opposite the abutting edges mentioned. By pressing down the free ends of these tongues, the catches can be released again and the contact modules on the cable connection side can be pulled out of the frame.

In a particularly advantageous embodiment of the contact modules according to the invention it is provided that the elastic tongues are articulated on the plug-in connection side of the frame insert sections so that their free ends point towards the cable connection side, the contact module being insertable into a module insert frame from this cable connection side. It is also particularly advantageous to design the contact modules in such a way that the tongues only engage the inside of the frame and do not surround the outside, so that the tongues largely prevent damage are protected and cannot get caught or break off when the contact modules are inserted into the frame.

A connector combination according to the invention is characterized in that the module insert frames in both connector housing parts are identical to one another and each have identical means for fixing plug contact modules as well as socket contact modules, that the pin contact modules and the socket contact modules include frame insert sections of the same design, and that combined protective contact and Guide means complementary to each other, d. H. on the one hand positive / male and on the other hand negative / female, each with a single protective contact element, so that two module insert frames can be plugged together with each other.

The connector housings have mutually complementary locking means. Such locking means are to be arranged such that they include, for example, locking clips on one housing and corresponding locking pins on the other housing, so that when two connector housings are brought together, the locking clips of one housing engage behind the locking pins of the other housing.

At least one of the housings is to be provided with suitable sealing means at the mutually connecting openings. When plugged into one another, the housings should engage in one another in such a way that they can absorb transverse forces relative to the plug connection direction and thereby keep the contact modules free of such forces.

Locking latches and pins of this type are known and are described, for example, in EP 0 405 168.

Figures 1 to 4 are described together below. They show the type of the uniform module insertion frame 1 on which a rectangular receiving opening 3 between two cheek parts 4, 5 and two head pieces 6, 7 can be seen. A connector connection side 8 and a cable connection side 9 are identified on the frame 1. Leave on the head pieces 6, 7 recognize first and second guide elements 10, 11 directed towards the connector side and aligned in the direction of connector axis A. The guide element 10 has the shape of a rib with a first somewhat wider and shorter rib part 12 and a narrower rib part 13 with a greater length and a resulting cam projection 14. The guide element 11 is essentially in the form of a column with a T-shaped cross section , which has a central slot 15. This slot has a first narrower section 16 that opens outwards and a section 17 that is widened in comparison, which section is designed with a bottom recess 18 in which a central rivet 19 is formed in one piece. The guide element 10 and the slot 15 in the guide element 11 are each designed symmetrically to the longitudinal center plane B and arranged approximately symmetrically relative to one another to the longitudinal center plane C. The shape of the slot 15 is complementary to the shape of the rib-shaped guide element 10; the height of the cam projection 14 corresponds to the depth of the bottom recess 18 of the slot section 17.

In the head pieces 6, 7 clamping screws 21, 22 with spring washers 23, 24 are inserted. These are used to connect protective contact conductors. Furthermore, through holes 25, 26, 27, 28 are provided in the head pieces 6, 7 for fastening the frame in a connector housing. In the cheek parts 4, 5 there are four openings in the form of rectangular windows 29, 30, 31, 32, 33, 34, 35, 36. Guide pockets 37, 38, 39, 40, 41, 42, 43, 44 are provided on the inside of the cheeks around these windows. The window bars 45, 46 on the cable connection side have the same material thickness as the cheeks in the region of the guide pockets 37, 38, 39, 40, 41, 42, 43, 44; the window bars 47, 48 on the connector side are delimited by stop edges 49, 50 which seal the guide pockets 37, 38, 39, 40, 41, 42, 43, 44 on one side. Of two in the cheek parts 4, 5 opposite guide pockets 37/41, 38/42, 39/43, 40/44 is in each case wider than the other, so that appropriately designed contact modules can only be used with a certain clear orientation.

Figures 5 to 10 are described below together. FIGS. 5 and 9 show a first module insertion frame 1 in the position like the frame in FIG. 3, but only in a partial section; FIGS. 7 and 9 show a second module insertion frame 2 in the position like the frame in FIG. 1, but in a partial section. The frames 1, 2 are shown in relation to each other in positions rotated by 180 ° about an axis perpendicular to the cutting plane. In FIG. 9, the frames 1, 2 according to FIGS. 5 and 7 are shown in a mutually assigned, mutually engaging position, as occurs when a plug connection is made between the connector housings, not shown here. The essential details are designated by the same reference numerals as known from FIGS. 1 to 4 and have the same meaning. The details are designated by index 1 for frame 1 and index 2 for frame 2.

The sectional view on the left-hand side of FIG. 9 shows how the rib-shaped guide element 10 _{1 of} the frame 1 engages in the slot 15 _{2 of} the guide element 11 _{2 of} the frame 2. Correspondingly, it can be seen at least in a hint that the rib-shaped guide body 10 _{2 of} the frame 2 engages in the undetectable slot of the guide body 11 _{1 of} the frame 1.

In FIGS. 5, 7, and 9, each of which is associated with a sectional view 6, 8, and 10, the rib-shaped shape of the guide element 10 ₁ in FIG. 6 can also be seen in detail, as well as the slot shape of the constant width of the slot 15 ₂ in the guide element 11 ₂ in FIG. 8. As another The detail can be seen in FIGS. 8 and 10, a U-shaped protective contact spring 20 ₂ , which is fastened to the rivet body 19 ₂ in the bottom recess 18 _{2 of} the slot 15 ₂ . The spring 20 establishes a conductive protective contact between the two module insertion frames 1, 2. Since the frames are metallically conductive, only one protective contact conductor has to be connected to one of the clamping screws 22, 23.

In the illustrations, play is provided on all sides between the mutually engaging guide elements 10, 11. The guide elements 10, 11 are used for the first mutual insertion when establishing a plug connection between two plug connector housings. Shear forces - based on the connector axis A - between the connector housings are absorbed by direct contact between the two connector housings in the case of an existing connector.

Figures 11 to 22 are described together below. The illustration of the module insertion frames 1, 2 in FIGS. 11 to 14, 15 to 18 and 19 to 22 corresponds to the illustration of FIGS. 5 to 8 with respect to the details shown. The discernible differences are that, in contrast to the frames from FIGS. 5 to 8, which have four pairs of windows in the cheek parts 4, 5, the number of pairs of windows is reduced here, specifically in FIGS. 11 to 14 on three pairs, in Figures 15 to 18 on two pairs and in Figures 19 to 22 on one pair. Since the size of the windows and their distance from each other and from the head pieces remain unchanged, the overall length of the frames is reduced.

Figures 23 to 29 are described together below. 23, 25, 27 and 29, pin contact modules 51 are shown in various designs; 24, 26 and 28, socket contact modules 52 are implemented shown, which is designed for the plug connection with the pin contact modules 51 according to FIGS. 23, 25 and 27. The pin contact modules 51 have a cable connection part 53, a central housing insert part 54 and a front plug connection part 55 lying in the direction of the plug connection axis A. The socket contact insert 52 has a cable connection section 56, a frame insertion section 57 and a plug connection section 58 one behind the other in the direction of the plug connection axis. The outer contour of the cable connection sections 53, 56 both on the pin contact modules 51 and on the socket contact modules 52 in FIGS. 23 and 24 correspond to one another, but this is not essential for the function. A cable connection section is not particularly pronounced in FIGS. 25 to 29.

The outer contours and the structural details of the frame insert sections 54, 57 on the pin contact modules 51 on the one hand and on the socket contact modules 52 on the other hand, are completely identical. This enables the combination of both module types of your choice with the uniform module insertion frame according to the invention. The connector sections 55 on the pin contact modules 51 and the connector sections 58 on the socket contact modules 52 are essentially complementary to one another, so that they engage when a plug connection is made between two connector housings. On the pin contact modules 51, the connector sections 55 are frame-shaped so that they surround the block-shaped connector sections 58 of the socket contact modules 52 on the outside in a leading manner in order to extend the creepage distances.

On opposite side surfaces of the frame insert sections 54, 57, guide bases 59, 60, 61, 62 are attached on both sides, which are essentially rectangularly limited and which, when a contact module is inserted into a module insert frame, move in the direction of the connector axis with it Fit the outer contour in pairs of opposing guide pockets 37/41, 38/42, 39/43, 40/44 in the cheek parts of the frame, the stop edges 49, 50 forming an end stop that fixes the position of the contact modules within the frame. One of the opposite guide bases 59, 60, 61, 62 is wider than the other, so that the contact modules can only be inserted into the frame with a certain clear orientation. In the center of the guide bases 59, 60, 61, 62 are individual resilient tongues 63, 64, 67, 68, articulated on one side, which extend from the edges facing the stop edges 49, 50 and each have a transverse groove 65, at the free ends thereof. 66, 69, 70 is formed. The width of the tongues 63, 64, 67, 68 is less than the width of the windows 29, 30, 31, 32, 33, 34, 35, 36 in the cheek parts of the frame. When a contact module is inserted into a frame in the direction of the plug connection axis, when the guide bases 59, 60, 61, 62 stop on the stop edges 49, 50, the opposite window webs 45, 46 snap into the transverse grooves 65, 66, 69, 70 of the tongues 63, 64 , 67, 68 a. The plug-in contact modules can be released from the frame by deliberately pressing down the two opposite tongues 63, 64, 67, 68 by exerting pressure on the free ends of the tongues. The plug-in contact modules 51, 52 used are secured in the frame against any movement, so that plug connections between two connector housings with inserted module insert frames with matched plug-in contact modules or sets of plug-in contact modules can be produced.

The design of the pin contact elements 73 or socket contact elements 78 within the contact modules is known in principle. A through-opening 71, 76 from the connection side to the plug connection side must be provided for each contact element. The contact elements 73, 78 are locked in the elastic plastic material of the contact modules 51, 52 by means of the engagement of an inner collar 72, 77 in an annular groove 74, 79.

In FIG. 23, a cable connection socket 75 can be seen at the rear on two power pin contact elements 73. In addition to the power pin contact elements 73, two switch contact elements 85 of essentially the same design and attachment are shown. However, they are shorter relative to the corresponding socket contact element, so that they are interrupted when a plug connection is disconnected before the power contact elements. This controls a power contactor that interrupts the power supply to the power contact elements.

In FIG. 24, a cable connection socket 80 is provided on the rear of two resilient power socket contact elements 76. In addition to the two power socket contact elements 76, two switching socket contact elements 86 of essentially the same design and fastening are provided, which interact with the previously mentioned switching pin contact elements 85 from FIG. 23 in the manner already described.

Only the basic housing of a multi-pin contact module 51 is shown in FIG. The through opening 71 for inserting the contact pins is provided on the plug connection side in an alternating diagonal grid with insulating collar 99.

FIG. 26 shows a housing of a multi-contact socket module 52, in which the through openings 76 for the contact sockets are provided in a diagonal grid with countersinks 100 for the aforementioned insulating collars 99 from FIG. 25 on the plug connection side.

FIG. 27 shows pin contact elements 84 which have spring contact connections. Tools can be inserted through the cable connection-side mounting openings 81, which deform the spring clamping bracket 82 so that a cable end can be inserted into a connection opening 83 and the cable end is clamped when the spring clamping bracket 82 is relieved. The contact elements 84 are fastened in a suitable manner in the contact insert 51. There are six contacts combined in one contact insert.

It can be seen from FIG. 28 that the shape and the number of electrical contact elements (in this case pin contacts) can be varied in many ways within a plug-in contact module, with the size also reducing the electrical load capacity. From a) to e) there are successive variations a) with one power contact for 100 A and two switching contacts, b) with two power contacts for 63 A and two switching contacts, c) with six contacts for 40 A each, d) with eight contacts for 16 A and e) with fifteen contacts each for 10 A maximum load. The scale is 1: 1.

In FIG. 29 a) it can be seen in vertical section how a pin contact module 51 is inserted in a first module insertion frame 1 and in FIG. 29 b) how a socket contact module 52 is inserted in a second module insertion frame 2. With regard to the details, reference is made to the terms from the description of FIGS. 23 to 27; Matching details are given the same reference numerals here. It can be seen how the lower edges of the base each rest on the stop edges and the grooves of the tongues snap into the upper window webs of the frames. In this way, a plug connection can be produced as shown in FIG. 29c). The frame-shaped connector section of the pin contact module 51 includes the block-shaped connector section of the socket contact module 52 in such a way that the effective creepage distances are extended. As before Shown and described previously, the module insert frames 1, 2 enter into an electrically conductive connection with one another at least via the protective contact springs 20.

In FIG. 30, a connector housing connector part 101 and a connector housing lower part 102 are shown in an assigned position when the connector has been produced. A sealing rubber 103 seals the housing openings lying one on top of the other. In the connector part 101 there is necessarily a cable lead-through to the outside, which in the sections shown (FIG. 30a): longitudinal section; Figure 30b): cross section) is not recognizable. A first module insertion frame 1 is inserted into the plug part 101 and screwed to it. A second module insertion frame 2 is inserted and screwed into the lower plug part 102. Relative to one another, the two frames 1, 2 assume the relative position to one another that has already been illustrated and explained in FIGS. 9 and 10.

In this illustration, no contact modules are inserted into the frame. However, it is readily understandable that the contact modules to be inserted into the frame in order to produce a complete plug connection will assume the relative position to one another which can be seen in FIG. 29c.
