Waterproof electric connector assembly

Abstract

The invention discloses a waterproof electric connector assembly, which comprises a plug and a socket. A lock sleeve is fixedly installed on the rear portion of the periphery of a socket casing in sealed and sleeved mode, an inserting gap for an inserting tube body of the plug to enter is reserved between the inner wall of the front portion of the lock sleeve and an inserting column body, a sealing ring used for being matched with the inserting tube body in sealed mode is embedded on the inner wall of the lock sleeve, an annular lock groove is arranged on the outer circumference of the inserting tube body of the plug, the lock sleeve is provided with a lock hole penetrating through the sleeve wall of the lock sleeve and a lock cylinder which is movably installed in the lock hole and used for being clamped in the lock groove of the plug, and a push-pull locking cap is movably installed on the periphery of a plug casing in sleeved mode along the front and back direction. The waterproof electric connector assembly adopts the push-pull lock cylinder to achieve rapid connection and locking of the plug and the socket, the sealing ring between the opposite surfaces of the inserting tube body and the lock sleeve is adopted to achieve circumferential sealing between the inserting tube body of the plug casing and the lock sleeve fixedly connected onto the socket casing, and sealing is achieved between the socket casing and the lock sleeve. Therefore, an inserting portion of the plug and the socket achieves sealing which is not prone to become invalid.

Description

technical field [0001] The present invention relates to electrical connectors. Background technique [0002] An existing electrical connector assembly with a built-in RJ-45 interface includes such as Figure 1-Figure 2 The plug shown 1, such as Figure 3-Figure 4 As shown in the socket 2, the male RJ-45 interface 11 is fixed on the front end of the plug housing 10, and the front end of the plug housing 10 is also provided with two guide columns 14, 15, large and small, on both sides of the male RJ-45 interface 11, and the plug housing 10 The front part of the outer circumference is rotatably fitted with a connecting nut 12 with an inner curved groove. The connecting nut 12 is also provided with a sealing ring 13 on the front end face of the plug housing 10 for sealing and matching with the socket. The female RJ- The 45 interface 21 is fixed in the columnar socket housing 20, and the socket housing 20 is provided with two guide grooves on both sides of the female RJ-45 inter...

Problems solved by technology

In addition, since the sealing ring 13 between the front end faces of the plug 1 and the socket 2 is a non-metallic elastic member when the plug 1 and the socket 2 are mated, the shielding performance of the mated end after mating is poor, and it is easy to cause electromagnetic leakage.
