Problems solved by technology

[0005] The object of the present invention is to provide a grinding method for a rectangular electrical connector, which solves the problem of mechanical stress and thermal stress generated when grinding the bonding surface of the electrical connector in the prior art, which in turn causes the glass that is sealed with the socket Cracks will occur, which will affect the sealing performance and insulation performance of the glass. At the same time, it will also cause problems such as the surface roughness of the bonding surface of the electrical connector not meeting the requirements.

Embodiment 1

[0030] A grinding method for a rectangular electrical connector, comprising the steps of:

[0031] (1) After installing the 5000-mesh grinding wheel on the grinding machine, first repair the side of the grinding wheel, and then repair the end face of the grinding wheel to obtain the verticality;

[0032] (2) The special fixture should be placed flat and kept vertically downward to assemble the special fixture with the electrical connector, and then install the special fixture on the platform of the grinding machine; if the electrical connection cannot be assembled with the special fixture, it should be checked Whether the special fixture is blocked and whether the needle body of the electrical connector is bent; after the assembly is successful, you should also check whether the needle body of the electrical connector is flat. If the distance between the needle body and the end face of the fixture is inconsistent, the product is unqualified and cannot be processed this time;

Abstract

The invention discloses a grinding method for a rectangular electric connector, and relates to the technical field of electric connector machining. The method mainly comprises the following steps that 1) a grinding wheel is mounted; 2) the electric connector is assembled on a special clamp; 3) grinding machine tool setting and grinding machining are carried out; 4) the electric connector is put into absolute ethyl alcohol to be subjected to dehydration treatment; 5) the electric connector is cleaned and blow-dried; and 6) the electric connector is dried and product detection is carried out. By means of the method, mechanical stress and thermal stress generated during grinding work are effectively reduced, then the situation that glass sealed in a jack cracks is avoided, the sealing performance and the insulating performance of the electric connector are guaranteed, meanwhile, the surface roughness of the bonding face of the electric connector is improved, subsequent machining of the electric connector is facilitated, product quality and production efficiency can be improved, the operation is easy, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of electrical connector processing, in particular to a grinding method for a rectangular electrical connector. Background technique [0002] In addition to meeting the general performance requirements, the electrical connector must meet good contact, reliable operation, and easy maintenance. Whether the electrical connector is reliable or not directly affects the normal operation of the circuit and involves the safety of the entire host. For this reason, the host circuit has very strict requirements on the quality and reliability of the electrical connector, and because of the high quality and reliability of the electrical connector, it is also widely used in military systems such as aviation, aerospace, and national defense. [0003] Most of the existing electrical connectors are composed of a metal shell, a glass base, and multiple socket contacts. Most of the manufacturing process is to encapsulate the me...
