Problems solved by technology

However, because the terminal is made of copper alloy and the shielding piece is made of stainless steel, the components of the two are different, and the melting point is different. The spot welding technique may cause empty welding, so that no good electrical connection is formed between the grounding terminal and the shielding piece. sexual connection

Abstract

An electrical connector, comprising an insulating body, a conductive terminal carried in the insulating body, and a metal piece, the insulating body includes a base and a docking portion, the conductive terminal includes a contact portion extending to the docking portion and a contact portion extending out of the base The conductive terminal includes a ground terminal 20G, the ground terminal has a first welding portion 24, and the metal piece has a second welding portion 34. The first welding part and the second welding part are joined together by spot welding, and the welding surfaces of the first and second welding parts are covered with solder. The invention realizes good welding through the combination of spot welding and soldering tin technology, especially small component metal elements of different materials.

Description

【Technical field】 [0001] The invention relates to an electrical connector. 【Background technique】 [0002] Chinese Utility Model No. CN204809558U discloses a USB Type-C receptacle connector, which can be inserted into a corresponding plug connector in both forward and reverse directions. The socket connector includes an upper row of terminals, a lower row of terminals and a metal shielding sheet between the upper and lower rows of terminals. The ground terminals and the shielding sheets in the upper and lower rows of terminals respectively extend out of wing parts, and the wing parts are welded together. Spot welding technology, especially laser spot welding technology is widely used in Type-C, and the above-mentioned wings are usually welded together by laser spot welding. However, because the terminal is made of copper alloy and the shielding piece is made of stainless steel, the components of the two are different, and the melting point is different. The spot welding te...
