Fisheye terminal

Abstract

The invention discloses a fisheye terminal. The fisheye terminal comprises a main body part and a plug part arranged at the end part of the main body part, wherein the plug part is of a symmetrical four-leg structure with a closed end part, support legs of the four-leg structure are bent, and when the plug part is inserted into a PCB hole, the outer side arc surfaces of the support legs of the four-leg structure are pressed against the inner wall of the PCB hole. According to the terminal, through appearance design of the terminal plug part, when the terminal is inserted into a PCB hole, four contact points exist between the terminal and the hole, during extrusion, the PCB hole can uniformly deform towards the periphery, the PCB is prevented from being damaged by excessive deformation of the PCB hole towards one direction, through four-point contact, the position of the terminal can be corrected, alignment of the PCB hole in the center of the terminal is ensured, and the service life is prolonged; and the four support legs are bent, so the terminals can be better guided into the PCB holes, hard interference is avoided, and practicability is higher.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a fisheye terminal. Background technique [0002] With the rapid development and popularization of new energy vehicles, the requirements for automotive electrical systems are getting higher and higher, and electronic connectors are key components for power and signal transmission, and the quality of connectors directly affects the performance of the entire electrical system. Therefore , People pay more and more attention to the reliability of electronic connectors. [0003] In the field of electronic connectors, fisheye terminals are more and more widely used. They have the characteristics of small insertion force, short process, anti-vibration, tolerance compensation and small damage to printed circuit board holes. In actual use, one end is connected to the PCB board by crimping, and the other end is soldered to the DBC surface inside the IGBT module by reflow so...

Problems solved by technology

[0004] Existing fisheye terminals, such as a fisheye terminal disclosed in Patent No. 202010923768.1, have a relatively flat insertion part at the end, and when inserted into a PBC hole, due to uneven force on the inner wall of the PBC hole, the PBC hole The expansion to the surrounding area is not uniform enough, and the PCB hole may deform too much in one direction and damage the PCB board, so it is necessary to improve the design in a targeted manner
