Abstract
A VGA interface comprises a plug and a socket. The socket comprises six pins, a pin plate, a bottom pin plate and a D-shaped iron ring. Six circular holes are formed in the pin plate, and the D-shaped iron ring is connected to the pin plate and is in a protruding state. The six pins are in a cap shape, and are arranged in the six circular holes in the pin plate in a sleeved mode. Springs are arranged behind the pins, and the bottom pin plate is arranged behind the springs. The plug comprises a base, contacts and a D-shaped magnetic steel ring embedded in the base. The middle portion of the base is in a protruding state in the D-shaped magnetic steel ring. The protruding face of the middle portion of the base is provided with the six contacts. The VGA interface has the advantages that connection is easy to conduct, the service life is prolonged, and the VGA interface is not prone to damage.
Description
Technical field
The invention belongs to electric component, specially refer to a kind of VGA interface.
Background technology
Common VGA interface, adopts 15 pin connected modes; Its socket is provided with 15 jacks, and plug is provided with 15 stitch, and the stitch of plug is with a circle metal shell outward.There is following defect in this common VGA interface:
One, in actual application, while generally transmitting data, only use red primary, green primary, blue primary, capable synchronous, field sync signal line, and common VGA interface is provided with 15 stitch connections, some is unnecessary;
Two, often plug is plugged (as notebook connects projection teaching, usually can plug operation) of operation, easily cause the jack of socket lax, and cause loose contact;
Three, when the VGA of some equipment socket is not to be placed in very obvious local time, plug is connected to socket more difficult, and easily the stitch of plug is distorted;
Four, when plug falls on the ground, easily cause housing distortion, so that can not insert socket.
Summary of the invention
The problem existing in order to solve above-mentioned common VGA interface, a kind of VGA interface provided by the invention, has reduced the stitch connecting, and is more easily connected, improves useful life, not fragile between plug and socket.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of VGA interface, comprises plug and socket; Described socket, comprises stitch, stitch plate, stitch base plate and D shape iron hoop; Described stitch plate has 6 circular holes, and described D shape iron hoop is connected on stitch plate, is protruding state; Described stitch has 6, and stitch is hat-shaped, and 6 stitch are enclosed within 6 circular holes of stitch plate; After stitch, be provided with spring, after spring, be provided with stitch base plate.In 6 stitch, have 5 to be connected with red, green, the blue fundamental color holding wire of VGA and line synchronizing signal line and field sync signal line respectively, the 6th stitch and D shape iron hoop link together, and link together with shielding conductor and the ground wire red, green, blue fundamental color of VGA.
Described plug, comprises base, contact, D shape magnet steel ring; Described D shape magnet steel ring, is embedded in base; Described base, intermediate portion is protruding state in D shape magnet steel ring; This one side protruding at base mid portion is provided with 6 contacts, and described contact adopts circular metal plate.The connected mode of 6 contacts and VGA line, corresponding with the stitch connected mode of socket, wherein there are 5 contacts to be connected with red, green, the blue fundamental color holding wire of VGA and line synchronizing signal line and field sync signal line respectively, the 6th contact and D shape magnet steel ring link together, and link together with shielding conductor and the ground wire red, green, blue fundamental color of VGA.
Further, described contact, adopts metallic copper, not oxidizable.
In the connection procedure of plug and socket, because of the present invention's design is not the connection of stitch to jack, and insert the inside of the part alignment socket D shape iron hoop that only plug base need to be protruded, the stitch of socket can be aimed at the contact on plug naturally, is very easy to so connect; Because the D shape magnet steel ring on plug has stronger magnetic attracting force, stick together with the D shape iron hoop on socket in addition, played the effect that is difficult for dropping.
Moreover common VGA plug, is protected by 15 stitch and a very thin metal shell; while dropping on the ground, easily cause housing distortion or improper processing ease stitch to distort; and the plug of the present invention's design is not design stitch, thus just not fragile, extend useful life.
Beneficial effect of the present invention is mainly manifested in: easily connect, improve useful life, not fragile.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment of the present invention VGA socket.
Fig. 2 is the structural representation of embodiment of the present invention VGA plug.
Fig. 3 is a schematic cross-section after embodiment of the present invention VGA socket and plug connects.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are further described.
A kind of VGA interface, comprises plug and socket; Described socket, is shown in shown in Fig. 1 and Fig. 3, comprises stitch a1～a6, stitch plate 1, stitch base plate 2 and D shape iron hoop 3; Stitch plate 1 has 6 circular holes; Described D shape iron hoop 3 is connected on stitch plate 1, is protruding state; Stitch a1～a6 is hat-shaped, and 6 stitch a1～a6 are enclosed within 6 circular holes of stitch plate 1; After stitch, be provided with spring 4, after spring, be provided with stitch base plate 2; Described stitch plate 1 or stitch base plate 2 are all to adopt insulating material.
6 stitch a1～a6 with being connected of VGA line are: stitch a1 is connected with the red primary signal line of VGA, stitch a2 is connected with the green primary signal line of VGA, stitch a3 is connected with the blue fundamental color holding wire of VGA, stitch a4 is connected with the line synchronizing signal line of VGA, stitch a5 is connected with the field sync signal line of VGA, and the shielding conductor of stitch a6 and VGA and ground wire D shape iron hoop 3 red, green, blue fundamental color link together.
Described plug, is shown in shown in Fig. 2 and Fig. 3, comprises base 5, contact b1～b6, D shape magnet steel ring 6; Described D shape magnet steel ring 6, is embedded in base 5; Described base, adopts insulating material, and the mid portion of base 5 is protruding state in D shape magnet steel ring 6; This one side protruding at base mid portion is provided with 6 contact b1～b6, and described contact b1～b6 adopts circular copper sheet.
6 contact b1～b6 with being connected of VGA line are: contact b1 is connected with the red primary signal line of VGA, contact b2 is connected with the green primary signal line of VGA, contact b3 is connected with the blue fundamental color holding wire of VGA, contact b4 is connected with the line synchronizing signal line of VGA, contact b5 is connected with the field sync signal line of VGA, and the shielding conductor of contact b6 and VGA and ground wire D shape magnet steel ring 6 red, green, blue fundamental color link together.
In present embodiment, after plug is connected with socket, because of the attraction of the D shape magnet steel ring on plug, stick together with the D shape iron hoop on socket, and stitch is because the pressure of plug is toward the inner extruding of socket, again because of the elasticity of the spring after stitch by stitch to extrapolation, just making has good contacting between stitch and contact.
Above-described is only preferably execution mode of one of the present invention, and to one skilled in the art, under the premise without departing from the principles of the invention, some of making change, and all should be considered as belonging to protection scope of the present invention.
