Female pin for cable connector

Abstract

The invention discloses a female pin for a cable connector. The female pin for the cable connector comprises a cylindrical terminal body and an elastic tightening device; an inner hole is formed in the end part of the terminal body; a plurality of axial straight slots are formed in the wall of the inner hole from the end part to form clamping claws in the circumferential direction; annular slots are formed in the outer wall of the clamping claws; the elastic tightening device sleeves the outer walls of the annular slot to tighten the clamping claw. The female pin for the cable connector is characterized in that an elastic sleeve or an elastic ring is used as the elastic tightening device; the elastic sleeve is an opened elastic metal sleeve of which the sidewall is opened. With the adoption of the female pin for the cable connector, the tightening force of the clamping claws can be remained for a long term; when in use, a good contact can be kept with a cylindrical male pin, and therefore, the phenomena of bad contact and sparking occurring in contact with the cylindrical male pin can be avoided.

Description

technical field [0001] The invention relates to a socket pin, in particular to a female socket pin in a cable connector used in machine tools, industrial robots, manipulators, and industrial automation equipment. Background technique [0002] The cable connectors used in machine tools, industrial robots, manipulators, industrial automation equipment, etc. are equipped with female pins, which are set in the inner core. In use, in order to facilitate the insertion of cylindrical male pins, the female pins used for cable connectors in the prior art are provided with axial straight grooves starting from the end on the side wall of the inner hole at the end to form a jaw structure When in use, the cylindrical male pin is inserted into the claw at the end of the female pin of the cable connector, and the claw is slightly stretched, and the claw relies on elastic deformation to clamp the cylindrical male pin to achieve electrical connection. This kind of female contact pin has a s...

AI Technical Summary

Problems solved by technology

This kind of female pin has a simple structure, but it has the following defects: because the female pin of the cable connector needs better conductivity, its jaws are generally made of copper material or copper material with silver plating on the surface, and the jaws can be used for a long time. During use, it will gradually lose its elasticity due to fatigue. After the cylindrical male pin is inserted, the tightening force of the jaws will decrease, which may cause poor contact and sparking. Therefore, the cable connector using this female pin short service life
