Abstract

The invention discloses a punch-formed fisheye terminal. The punch-formed fisheye terminal comprises a main rod part and an integrally-formed plug part arranged at one end of the main rod part, wherein two reversely-bent first cantilever beams are symmetrically arranged at the middle portion of the main rod part, two sections of straight beams are arranged between the first cantilever beams, and the free ends of the two sections of straight beams are opposite and have a gap. According to the fisheye terminal, the two reversely bent first cantilever beams are arranged, so a buffer effect is achieved when the fisheye terminal is mounted on a PCB, and ceramic cracking caused by sudden change of stress on a DBC is avoided; meanwhile, due to the two sections of straight beam structures, the overall strength of the terminal can be improved, and plastic deformation caused by excessive stress of the terminal can be prevented; and therefore, the fisheye terminal has the advantages of easiness in manufacturing, improved product reliability, enhanced production efficiency, capability of reducing cost by reducing failures and the like.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a stamped 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 r...
