Metal wire clip of tail end fixing cable

Abstract

The invention discloses a metal wire clip of a tail end fixing cable, which comprises the metal wire clip, a connector and an outgoing wire sleeve, and is characterized in that the outgoing wire sleeve comprises a flange, an outgoing wire tube and a wire pressing tube; the flange is a rectangular plate which is provided with a central through hole and a step; the outgoing wire tube is a sleeve with a platform in the middle and respectively a saw tooth-shaped cylindrical surface and a knurled cylindrical surface on both ends; the outgoing wire tube is sleeved with the flange, and the knurled cylindrical surface of the outgoing wire tube and a circular groove are in flanging compaction riveting; the wire pressing tube is sleeved on the saw tooth-shaped cylindrical surface; a port on one side of the metal wire clip is provided with a groove; the outgoing wire sleeve is sleeved in the groove; and the connector is fixedly arranged on the port on the other side of the metal wire clip through a screw. Compared with the prior art, the metal wire clip of the tail end fixing cable has a simple structure and is convenient to assemble, the wire clamping is firm and durable, the grounding of a shield layer is convenient, the anti-disturbance from environment is strong, the cable alternation is good, and outgoing wire tubes which are matched with the cables diameter can be selected, combined and used on demand.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a metal wire clip used for fixing cables at the tail end of an electrical connector. Background technique [0002] In the application of electrical connectors, there are many electrical connectors that need to weld wires at the tail of the contact terminal. Among them, there are a series of factors such as protecting the welding part of the connector, supporting hot plugging and insulation blocking of some devices, and electromagnetic interference shielding. Considering that it usually needs to be used with metal wire clips. Due to the metal clamp of the prior art, the cable at the tail end is fixed by crimping the integrated outlet sleeve and the cable. Although the structure is simple, there are the following problems: [0003] , Dimensional intermatability is poor: the inner diameter of the outlet barrel of the integrated structure needs to be determined with ...

AI Technical Summary

Problems solved by technology

[0003] , Dimensional intermatability is poor: the inner diameter of the outlet barrel of the integrated structure needs to be determined with the outer diameter of the cable, and cables with different wire diameters need to be equipped with corresponding outlet barrels, which increases the processing cost of parts, and the diversification of models affects management cost

[0004] 2. Poor electromagnetic interference shielding effect: the outlet barrel and the cable are crimped and fixed once, and the shielding layer of the cable can only be welded on the inner wall of the metal clamp or the shell of the electrical connector to achieve grounding. The reliability of welding and the cable pressure The tightness of the connection directly affects the quality of the electromagnetic interference shielding effect
