Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a tail attachment of a four-way circular connector. Background Art

[0002] The electrical connector includes a plug and a socket. Usually, the plug is connected to the cable, and the socket is connected to the device to achieve the electrical connection between the cable and the device. The rear attachment of the connector is a component of the transition between the connector and the cable. Its main function is to reduce the bending stress between the connector and the cable, reduce the force at the termination of the cable and the connector, so as to protect the cable from excessive deformation, wear or breakage at the termination point of the connector. At the same time, by clamping the cable, the cable will not be pulled off when subjected to external force, protecting the internal signal of the connector for stable transmission.

[0003] The Chinese utility model patent (authorization announcement number: CN207967457U name: A cable clamping structure at the rear of a connector) includes a cable cover, a clamping plate, a semicircular elastic block, a set screw and a locking screw. The utility model adopts a cable cover axially connected with a section of a circular ring and a section of a semicircular ring. The circular ring section of the cable cover is connected to the connector, and the hanging ear of the semicircular ring section of the cable cover is connected to the hanging ear of the clamping plate. Two semicircular elastic blocks are arranged between the first slider groove of the cable cover and the second slider groove of the clamping plate. When the cable welded to the connector passes through the cable cover and the two semicircular elastic blocks, as the locking screw passes through the locking screw hole of the clamping plate and is locked with the locking internal thread of the cable cover, the two semicircular elastic blocks are squeezed by the clamping plate, the cable cover and the cable, and the telescopic holes of the two semicircular elastic blocks are compressed and deformed, and the cable is fixed between the clamping plate, the cable cover and the semicircular elastic block, so as to achieve the clamping and fixing of the cable at the rear of the connector. It has a simple structure, good clamping effect, and meets the use requirements of cables with different outer diameters. However, with the development of the market, the integrated use of connectors is increasing, and the space is getting smaller and smaller, so the wiring of a single connector is very dense, and the direction of the tail outlet is also diverse. The tail accessories of the connector may also need to clamp and fix cables in other directions. The above-mentioned tail accessories use a single hole for outlet, which cannot meet the market's demand for multiple cable directions and clamping and fixing. Utility Model Content
