Rotary grinding device for jack contact

Abstract

The invention relates to a rotary grinding device for a jack contact. The rotary grinding device is used for the field of processing of electric connector jack contacts. The rotary grinding device comprises a base, a power supply, a speed regulator, a motor fixing seat, a motor, a nut, a connecting shaft sleeve, a pin, a positioning block, a grinding needle positioning seat, a screw, a set screw,a protective cover, a threaded sleeve, a grinding needle and a protective cover, wherein the motor is connected with the power supply and the speed regulator through wires, and is mounted on the motorfixing seat, the motor fixing seat is mounted on the base, the motor and the connecting shaft sleeve are fixed through pins, the connecting shaft sleeve is connected with the grinding needle positioning seat through screws, and the grinding needle is mounted in the grinding needle fixing seat and fastened through the set screw; and the power supply drives the motor, the connecting shaft sleeve, the grinding needle positioning seat and the grinding needle to rotate so as to grind a jack contact reed. According to the rotary grinding device for the jack contact, grinding and polishing of the reed and the hole wall of the jack contact can be achieved, and the rotary grinding device is good in grinding quality, high in efficiency and convenient to use and maintain.

Description

technical field [0001] The invention relates to a socket contact piece rotary grinding device, which is mainly used in the field of electrical connector socket contact piece processing. Background technique [0002] In the field of electrical connectors, contacts are divided into male contacts and female contacts, also known as pin contacts and socket contacts, and there are many types of socket contacts. At present, there are mainly cylindrical socket contacts. , Wire spring socket contacts, reed contacts, crown belt socket contacts, etc. For cylindrical jack contacts, there are mainly two structures, one is a straight slotted jack, and the other is an oblique slotted jack, so the quality of the jack shrapnel directly affects the electrical performance of the electrical connector. At present, the straight slots or oblique slots of electrical connectors are generally processed by wire cutting and sheet milling cutters. After processing, sharp edges are formed at the mouth o...

AI Technical Summary

Problems solved by technology

At present, the straight slots or oblique slots of electrical connectors are generally processed by wire cutting and sheet milling cutters. After processing, sharp edges are formed at the mouth of the contact sheet. Because it is not easy to blunt inside the socket, At the same time, due to the deformation of the opening of the socket, the deformation of the contact piece is relatively large under the requirement of the insertion force, which causes a large pressure on the contact pin when it is mated with the contact pin, thus causing the contact pin to be mated and separated. It will cause certain damage to the pins and produce a small amount of excess. Before using the chute socket rotary grinding device, the insertion and withdrawal force and separation force of the single-piece socket and the connector as a whole are close to the upper limit, and the insertion and withdrawal force is tested. And a small amount of excess will be generated when mating

At the same time, the gold-plated layer will be damaged, causing corrosion of the pin contacts, resulting in failure of the electrical connector

[0003] In order to solve the quality problems existing in the existing chute sockets, it is very necessary to explore a method and device for improving the quality of the contact pieces of the chute sockets
