4pin connector manufacturing process

Abstract

A manufacture process of 4PIN connectors includes such steps as: 1, preparing bulk PINs according to size requirement; 2, arranging the pins; 3, performing flat pressing; 4, performing gold and tin electroplating; 5, cutting PINs; 6, performing bending; 7, performing cutting with an automatic machine; 8, plugging circuit board preset PINs by an automatic machine; 9, adding protective covers by anautomatic machine; 10, performing self-inspection by an automatic machine; 11, performing REEL packaging; 12, piling material rolls; 13, applying moisture-proof bags; 14, placing the materials into packing boxes; 15, sealing the packing boxes. The invention adopts the automatic production and assembly mode to produce and process the 4PIN connectors in 15 steps, which has high production and processing efficiency and low cost.

Description

technical field [0001] The invention relates to the technology in the field of connectors, in particular to a manufacturing process of a 4PIN connector. Background technique [0002] Traditional connectors consist of two parts: a plastic body and a terminal module. The terminal module is generally formed by stamping. However, stamping is generally suitable for flat sheet contact terminals, and cylindrical terminals need to be wrapped after stamping. Round shape, many processes and unstable quality after molding. The plastic body and the terminal module can be formed separately and then inserted into each other, or there are two ways of integral mosaic molding. Most of the experience in these manufacturing processes comes from the use of relatively flat USB, Type-C, Apple connectors, etc., but each connector has its own characteristics, and the process of traditional connectors cannot be directly applied to the 4PIN of the present invention. on the connector. However, most...
