The front end of the outer edge of the socket housing is evenly divided into three staples, and the socket housing There is a circular groove at the end of the socket, and an O-ring is arranged in the circular groove, and the O-ring is in contact with the inner wall of the tee shell; the tail end of the socket shell is provided with a convex key, and the convex key is in contact with the tee. Corresponds to the keyway on the housing.

Description

The triplet type electric connector

Technical field

The utility model relates to a kind of triplet type electric connector.

Background technology

At present, at the switching three-way connector that is used on the market on the main equipment, its structure is made up of three-way body, insulator, contact, Socket casing, grommet, lead and coupling nut, three interfaces of three-way body connect three Socket casings by coupling nut respectively, coupling nut and Socket casing are fixed with holding screw, coupling nut and three-way body link together with jump ring, insulator places the Socket casing inner chamber, the even branch of contact is in insulator, and the grommet that lead passes the Socket casing afterbody is connected with contact in three interfaces.The threeway electric connector of this kind structure, because between coupling nut and the three-way body is to be connected with jump ring, therefore, there is the slit in the place at the jump ring annular groove, there is the slit equally in the threaded connection place of coupling nut and Socket casing simultaneously, and the place, slit can't prevent the intrusion of dust and rainwater etc.

Summary of the invention

The purpose of this utility model provides a kind of triplet type electric connector that can prevent that dust and rainwater etc. from invading.

The technical solution of the utility model is: it is by three-way body, insulator, contact, Socket casing, grommet, lead and coupling nut are formed, three interfaces of three-way body connect three Socket casings by coupling nut respectively, coupling nut and Socket casing are fixed with holding screw, coupling nut [] inwall is provided with an annular groove, the three-way body cylindrical has the annular groove relative with the coupling nut inwall, annular groove is built-in with jump ring, insulator places the Socket casing inner chamber, the even branch of contact is in insulator, the grommet that lead passes the Socket casing afterbody is connected with contact in three interfaces, it is characterized in that, three bails of the even branch of the outer rim front end of Socket casing, the tail end of Socket casing has circular groove, and the O RunddichtringO is set in the circular groove, and the O RunddichtringO contacts with the inwall of three-way body; The breech face of Socket casing is provided with protruding key, and protruding key is corresponding with the keyway on the three-way body.

The utility model has the advantages that: the O RunddichtringO is packed into behind the groove of Socket casing afterbody, just bind round tightly on the footpath, the end of groove, and the periphery of protrusion groove, after the Socket casing afterbody inserts the three-way body internal diameter, the O RunddichtringO is because interference is subjected to radial compression, enrich between Socket casing and three-way body, realize the sealing at Socket casing and three-way body slit place, prevent that effectively dust and rainwater etc. from entering into electric connector inside by the slit between Socket casing and three-way body, reduce the performance of electric connector.Three bails of Socket casing front end and the bayonet socket connected mode that three crank slots on the adaptive plug form have and are connected fast, easy and simple to handle, lock advantages such as firm, reliable.The contact of identical contact is realized conducting by the crimping lead in three interfaces of threeway electric connector, thereby reaches the into threeway effect of scene 2.The unified shielding coating that adopts of the housing of threeway electric connector also has stronger environmental resistance in the effect of performance electronic shield.The structural design optimization of electric connector, accessory size is fastidious, and material selects rationally have little, the lightweight characteristics of volume.
