Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing：

Shown in please referring to Fig.1 to Fig.4, the utility model provides a kind of plugs and sockets connector, including male seat and female seat, The male seat includes that public rubber head 6, the first contact pin 10 in public rubber head 6 and the second contact pin 11, the female seat include rubber master batch First 3, the first jack 8 and the second jack 7 in rubber master batch head 3, external mold 2 are combined into one by being molded encapsulated and rubber master batch head 3 Body, 3 outer surface of rubber master batch head are equipped at least one annular groove.It is equipped with rubber cushion 5 and nut 4 successively on public affairs 6 external screw thread of rubber head, 6 front end of the public affairs rubber head is equipped with bulge loop 61, and 61 outer diameter of the bulge loop is more than the internal diameter of 2 front end of the external mold, 2 front end of the external mold For elastic tip, when 6 front end of the public affairs rubber head is inserted into the elastic tip of the external mold 2, the elastic tip of the external mold 2 is by the bulge loop 61 claddings, 6 outer surface of the public affairs rubber head is equipped with installs the error-proof structure to equipment for male seat.

The quantity of first jack, 8 and first contact pin is respectively two, the quantity of second jack, 7 and second contact pin 11 It it is respectively two, the diameter of first jack 8 is more than the diameter of second jack 7, and the diameter of first contact pin 10 is more than The diameter of second contact pin 11.

Preferably, the liquid-state epoxy resin curing agent instilled in the public rubber head 6 is inserted first respectively after high-temperature baking Needle 10 and 11 periphery of the second contact pin form solid waterproof layer 12.

Being screwed in successively on public affairs 6 external screw thread of rubber head has rubber cushion 5 and nut 4.

2 outer surface of the external mold is equipped with skid resistance strip 9, increases hand frictional force when plug, avoids sliding.

The operation principle of the utility model：The annular groove that 3 outer surface of rubber master batch head in the utility model is equipped with increases When injection molding with the degree of occlusion of external mold 2 so that external mold 2 and the connection of rubber master batch head 3 are more secured, while also greatly strengthening anti- Water effect.Using contact pin and jack to inserting the connection type of interworking, since jack has a certain depth, contact pin in jack repeatedly Side contact area is larger when plug, contact pin from playing the dirty effect of the automatic dust removed in jack when being extracted in jack, Pin head is not easy contamination, avoids because poor contact causes resistance value to increase or the phenomenon that can not be connected, when master-slave seat assembles For elastic conjunction, the elasticity of 2 front end of the external mold corrects the bulge loop on 6 head of public rubber head is wrapped in, realize good Water proof and dust proof effect.External mold 2 uses elastomeric high molecular material, shock resistance and damping performance to protrude.Public affairs 6 appearance of rubber head The error-proof structure that face is equipped with is the vertical plane being arranged between 6 external screw thread of the public rubber head, and the vertical plane constitutes one with external screw thread A D fonts error-proof structure, it is ensured that only exist a kind of installation direction when male seat is installed in equipment, improve the accurate of installation Property.

The above is only the preferred embodiment of the present invention, it is all done according to the utility model rights standards range it is equal Deng variation and modification, it should all belong to the covering scope of the utility model rights standards.
