Electric connector manufacturing method

Abstract

The invention discloses an electric connector manufacturing method comprising the following steps: S1, providing a bearing plate, wherein a plurality of receive slots are arranged at intervals on the bearing plate in a concave manner; S2, providing a plurality of solders placed in corresponding receive slots; S3, heating the bearing plate so as to soften the solders; S4, providing an insulator body and a plurality of terminals arranged on the insulator body, wherein the bottom of each terminal is provided with a welding portion exposed outside the insulator body, the insulator body and the terminals are wholly moved to the bearing plate, so the welding portions can insert corresponding softened solders; S5, bonding the solders on the welding portions, moving the insulator body from the position above the bearing plate, and allowing the solders to disengage from the bearing plate. The electric connector has excellent electrical connection performance; the electric connector manufacturing method can simplify the welding portion structure, can reduce the terminal making cost, can effectively prevent solders from falling off, can prevent the welding portion from forming empty solder and solder skips, and well welding the welding portions with a circuit board.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of an electrical connector, in particular to a manufacturing method of an electrical connector in which terminals are inserted into solder. 【Background technique】 [0002] With the rapid development of the electronics industry, the performance requirements and structural strength requirements of electronic products are getting higher and higher. In order to ensure that the electrical connectors inside the electronic products can be firmly welded to the circuit board, the common practice in the industry is to Enhance the effect of welding. An existing electrical connector includes an insulating body provided with a plurality of terminal grooves and a plurality of terminals fixed in the plurality of terminal grooves, and one end of the terminal has an elastic contact portion protruding from the insulating body. The top surface of the body is in contact with a chip module, and the other end has a solderin...

Problems solved by technology

[0003] However, if the solder ball is clamped and fixed by the side wall of the groove and the welding part, that is, the solder ball is against the side wall of the groove, when the electrical connector is soldered to the When the above-mentioned circuit board is used, the solder ball needs to be heat-treated. In this way, the solder ball will be heated to expand to squeeze the groove, causing the insulating body to deform or even warp, which is not only easy cause the solder balls to fall off, causing empty soldering between the soldering portion and the circuit board, and easily affecting the electrical contact between the elastic contact portion and the chip module, making the electrical connection of the electrical connector poor performance

If only relying on the soldering part itself for clamping and fixing, the structure of the soldering part needs to be designed to be more complicated to clamp the solder ball, so not only the cost is high, but also because the terminal is stamped and formed by a sheet metal. or bending and forming, so the thickness of the terminal is thinner, and the clamping force of the welding part is weaker, so that the solder balls are easy to fall during the movement or transportation of the electrical connector, resulting in the welding part with poor soldering of the circuit board
