Quick-change connector for cable

Abstract

The invention relates to a quick-change connector for a cable, so that a problem that an existing connector has a poor waterproof performance is solved. The quick-change connector comprises an auto-interfix type plug and a protecting cover that is matched with the plug. The plug includes a back-end packaging cable, a cable end sheath and a tail cap, wherein the front end of the tail cap is fixed with a main body by a screw thread and a positioning bolt. A plugging core head is arranged at the center of the front end of the main body; a pair of outer thread groove dops with a quarter of arc shapes are arranged at the periphery of the plugging core head of the main body, wherein the outer thread groove dops are distributed oppositely and stretched forwardly; and a locking handle is sleevedly installed between the outer thread groove dops and the tail cap, wherein a pair of inner thread tooth buckles with a quarter of arc shapes are arranged at the inner circumference of the front end of the locking handle and are cooperated with the outer thread groove dops of the butted main body of the plug. An elastic bulkhead that is used for enabling the plugging core head to be sealed and be in butt joint is fixedly installed at the front center of the protective cover; a pair of outer thread groove dops with a quarter of arc shapes are arranged at the protective cover, wherein the outer thread groove dops are stretched forwardly from the periphery of the elastic bulkhead and are cooperated with the inner thread tooth buckles of the locking handle of the plug; and the protective cover is connected with the tail cap of the plug through a standing wire. According to the invention, the quick-change connector has the following advantages: the rapid self-locking connection performance is excellent; the connector can withstand axial tensile forces and radial shearing forces without looseness and deformation; the connection and insertion speed is fast; the waterproofness performance is good; and the connector can be used conveniently.

Description

technical field [0001] The invention relates to a cable joint, in particular to a quick-change cable joint. Background technique [0002] The existing cable joint has the advantages of small axial tensile force and radial shear force, easy loosening and deformation, slow insertion speed and poor waterproof performance. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, and provide a quick-change cable joint. [0004] In order to achieve the above object, the cable quick-change joint of the present invention includes a self-interconnecting plug and a protective cover for the plug. The plug includes a rear end packaging cable and a cable end sheath, and the front end is fixed to the main body through a screw thread and a set screw. The tail cap, the center of the front end of the main body has a plug-in core head, and the main body is formed with a pair of quarter arc-shaped outer rib groove c...
