Description

Fisheye connector for power module

Technical Field

The utility model relates to the technical field of fish-eye contact pins, in particular to a power module fish-eye connector.

Background

The fish eye contact pin is used on a vehicle component and is mainly applied to each control module of an automobile electrical appliance, the fish eye head of the contact pin is directly pressed into a jack on the PCB, the contact pin is fixedly connected with the jack on the PCB by means of self elasticity of the fish eye hole, and signals are transmitted to each execution element through a control circuit. The fish eye contact pin is the most widely used connection structure for connecting the automobile connector with the PCB.

According to the fisheye terminal and the assembly thereof with the double-layer structure provided in the patent document with the application number of CN202120660529.1, the fisheye terminal with the double-layer structure comprises two layers of fisheye terminal units which are mutually bent to be laminated, attached and fixed together, wherein an extension piece is formed at the upper end of one layer of fisheye terminal unit in an extending manner, the thickness of the extension piece is equal to that of one layer of fisheye terminal unit, and the extension piece forms an elastic female terminal in a punching and/or bending manner. The thickness of the extension piece is 1/2 of the thickness of the fish-eye terminal with the double-layer structure, namely, the extension piece has good formability and raw material characteristics due to the fact that the thickness of the material is thinner, and flexible application can be met, so that the extension piece can form an elastic female terminal without a welding process in a stamping and/or bending mode, the technical characteristics of the elastic female terminal are completely the same as those of the elastic female terminal formed by a single material thickness, and the problem that a complex female terminal structure cannot be formed or is difficult to form due to the fact that the thickness of the material is thicker in a conventional fish-eye terminal is solved.

The fish-eye terminal with the double-layer structure and the assembly thereof solve the problem that the conventional fish-eye terminal cannot or is difficult to form a complex female terminal structure due to thicker material thickness. Because the fish eye contact pin is inserted into the PCB connecting hole, the contact surface between the fish eye contact pin and the PCB connecting hole is only provided with two oval side end points due to the oval design of the end head, so that the contact surface is small, and when the position of the end head is deviated, the end head is loose or separated from the PCB connecting hole to cause disconnection, thereby breaking the signal transmission of the system.
