Method for mfg. electric connector containing multi-conducting terminals and metal frame by plugging shaping method

Abstract

A method for manufacturing an electrical connector comprising a plurality of conductive terminals and a metal frame by insert molding, comprising presetting a core composed of conductive terminals and a metal frame into a mold cavity, wherein the metal frame includes a mounting surface and a plugging surface perpendicular to the mounting surface, and the conductive terminal includes a contact portion and a solder tail that are parallel to the mounting surface and the plugging surface of the metal frame respectively; The direction of the installation surface is inserted into the gap between two adjacent contact parts from the free end of the contact part of the conductive terminal to maintain a certain distance between the contact parts of each conductive terminal, and to move the removable second fixer along the direction of the metal The direction of the frame insertion surface is inserted from the free end of the welding tail of the conductive terminal into the gap between two adjacent welding tails, so as to keep the tails of each conductive terminal on the same plane; then inject a molten resin into the mold cavity, The molten resin forms an insulating shell on the peripheral surface of the core, which can combine the conductive terminal group and the metal frame and cover part of its area.

Description

technical field [0001] The present invention relates to a method of manufacturing an input / output connector of a computer or a communication device by insert molding, in particular to an insert molding method, wherein the electrical connector is formed by injection molding an insulating shell material, And during the formation of the insulating housing of the connector, the contact parts of a group of conductive terminals pre-placed in the mold cavity are kept coplanar, and the connector insertion molding method is maintained with equal spacing between the terminals. Background technique [0002] In the past, insert-molding was used in the manufacture of connectors, so that the conductive terminals, metal frame and insulating shell can be formed into an integral unit by injecting molten resin into the mold cavity with the conductive terminals and metal frame in advance. structure. However, this molding method tends to have the problem that the contact part of the conductive...

Problems solved by technology

However, this molding method tends to have the problem that the contact part of the conductive terminal is not easy to keep on the same plane during injection molding. The wall of the casing, and before the injection molding of the molten resin, because the wall has not yet been formed, there is a gap between the conductive terminal and the wall of the mold cavity that can accommodate the molding of the wall. Therefore, under the injection pressure, the molten The material will produce stresses directly on the terminals, causing changes or distortions in terminal spacing or coplanarity that reduce the expected precision of the connector
