Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a welding wire type connector male head. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors. The basic performance can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It is based on one insertion and one removal as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle is used as the basis for judgment.

[0003] In order to simplify the assembly process, the existing male connector adopts the method of assembling the terminal and the insulating part together by plugging them together. However, this assembly method not only makes the sealing performance of the plug-in connection between the terminal and the insulating part poor, resulting in poor waterproof performance, but also the front-to-back direction holding force between the terminal and the insulating part is insufficient after assembly, which is prone to PIN withdrawal, thereby affecting the working process of the connector. Therefore, it is necessary to make further improvements to the existing male connector structure. Utility Model Content

[0035] The terminal group 20 includes a plurality of male terminals 21, each of which is integrally provided with a boss 22 that protrudes outward and cooperates with the glue dispensing groove 102. The contact portion 23 of the male terminal 21 extends inwardly into the insertion cavity 101 through the first through hole 103, and the front end of the boss 22 abuts against the rear end surface of the glue dispensing groove 102, so that when the male terminal 21 is installed, the glue in the glue dispensing groove 102 can not only play a certain fixing effect on the male terminal 21, but also improve the sealing of the connection between the male terminal 21 and the insulating body 10, thereby effectively improving its waterproof performance; in the present embodiment, the rear end portion of the boss 22 extends outward from the glue dispensing groove 102; the male terminal 20 is formed by stamping and bending, thereby reducing its electroplating cost.
