Manufacturing method of electronic connector

Abstract

The invention discloses a manufacturing method of an electronic connector. The method comprises the steps that an iron material strap and a metal terminal are sequentially stamped at high speed, a socket body 4 is formed on the iron material strap in an injection molding mode, the PIN of the metal terminal is inserted into the socket body 4, a frame 8 is formed on the periphery of the socket body 4 in an injection molding mode, the iron material strap and the electronic connector are cut and separated, and therefore the finished electronic connector is obtained; the metal terminal is accurately and efficiently embedded into the insulating socket body 4 in the two-time injection molding mode, According to the manufacturing method of the electronic connector, the product rejection ratio is reduced, production efficiency is improved, the manufactured electronic connector has the higher quality stability compared with an electronic connector obtained in an assembling mode, the whole manufacturing process is fully automatic, the manufacturing method is easier and more convenient to implement compared with manual assembly, and the input cost is reduced.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a manufacturing method of an electronic connector. Background technique [0002] Electronic connectors are used to electrically connect two electronic components. The electronic connector generally includes an insulating body provided with a plurality of receiving holes and a plurality of conductive terminals correspondingly located in the receiving holes. In order to ensure The performance of the conductive terminal is good in terms of elasticity and life, and the conductive terminal is generally formed by punching and bending multiple metal plates to ensure the above-mentioned good performance. [0003] In order to form the electronic connector, one of the commonly used manufacturing methods in the industry is: first place a plurality of the conductive terminals punched and formed in a mold, then inject a liquid insulating material into the mold, form and cool The mold is then remove...

AI Technical Summary

Problems solved by technology

Its technical defects are: 1. When the structure of the conductive terminal is complicated, the structure of the receiving hole will become complicated correspondingly in order to match the conductive terminal. For example, the width of the receiving hole should be greater than or equal to the The width of the conductive terminal can make the conductive terminal fit into the receiving hole

The processing and manufacturing of the conductive terminals and the insulator is complicated and costly, which increases the manufacturing cost of the electronic connector, and makes the arrangement density of the conductive terminals in the insulating body relatively small, which is not conducive to the Electronic connector miniaturization development

[0005] 2. Since the conductive terminal has to be bent and formed before it is loaded into the receiving hole, it is inevitable that there will be deviations during molding, and there will be tolerances when mating with the receiving hole, resulting in the contact between the conductive terminal and the electronic card. The contact position is not accurate, which may cause some of the conductive terminals not to form an electrical path with the electronic card, which affects the normal electrical connection between the electronic connector and the electronic card
