Cable connector

Abstract

The invention discloses a cable connector which comprises a main pipe body, wherein a thread is arranged in the front end of the main pipe body; a pipe sleeve, wherein the tail end of the pipe sleeve is screwed in the front end of the main pipe body through threads, and the pipe sleeve is sleeved with a first sealing rubber ring and a second sealing rubber ring which are oppositely arranged, and the first sealing rubber ring is pressed at the front end of the main pipe body; a wiring terminal which is coaxial with the pipe sleeve, wherein the tail end is sleeved in the pipe sleeve and located on one side of the front end of the main pipe body, and the front end extends out of the pipe sleeve; and a fixing device; wherein threads are arranged inside the tail end of the fixing piece and screwed at the front end of the pipe sleeve; the second sealing rubber ring tightly presses the tail end of the fixing piece; and the front end of the wiring terminal extends into the fixing piece. The sealing rubber rings are additionally arranged at the joints of the pipe sleeve, so that the waterproof performance and the stability of the whole product are improved, quick connection is facilitated, and the use requirements in severe environments such as underground fully mechanized coal mining faces are met.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a cable connector. Background technique [0002] At present, cable connectors are mainly suitable for signal transmission between various digital program-controlled switches of transmission equipment bureaus, internal connections of photoelectric transmission equipment and distribution frames, and are used to transmit data, audio, video and other communication equipment. In the related art, the Chinese patent application publication number CN212874868U discloses a cable connector, including an outer shell, the outer shell includes a main body and a sleeve arranged at the front end of the main body; the outer wall of the front end of the main body is provided with threads, The pipe sleeve is screwed on the front end of the main body through threads; an insulating seat is provided inside the pipe sleeve, and a threading hole for the cable branch to pass through is provided on th...

Problems solved by technology

In view of the fact that the joint surface of the fixing part and the casing in the above-mentioned related technology does not consider the waterproof design, it cannot be used in the harsh environment of high temperature and high humidity in the fully mechanized mining face, the waterproof performance of the product is insufficient, and there is a safety hazard in the use of the continuous device It affects the stability of the product; and in the process of field use, the shaft gap of the gland hole of the connector is too small, which cannot meet the single-wire introduction of a 6 square 4-core cable for on-site mining. It is necessary to optimize the design of the gland hole shaft gap to meet the field use; finally There is no anti-loosening design for the thread fastening method of the pipe sleeve at the joint surface, which cannot meet the requirements of various working conditions
