AI Technical Summary

Technical Problem

The existing snap-fit sockets have a non-fully enclosed snap-fit connection between the pins and the socket body, resulting in insufficient locking strength and poor connection stability and reliability.

Method used

A closed-type claw and claw mounting groove structure is designed so that the claw can be engaged in the claw mounting groove of the pin. The limiting part and the positioning step surface ensure that it is difficult to disengage after being engaged. Combined with the sealing ring, the sealing performance is improved. The buckling structure between the rotating sleeve and the socket body enhances stability.

Benefits of technology

It achieves high locking strength and stability, improves the reliability and sealing of the snap-fit connection, and enhances the overall stability and safety of the socket structure.

Abstract

本实用新型公开了一种卡扣式插座结构，涉及电气连接技术领域，包括插针和插座主体，插针卡接套设于插座主体的插针孔内，插针孔的内周面沿插针安装方向依次设有限位部和卡爪，插针的外周部沿插针安装方向依次设有定位台阶面和用于安装卡爪的卡爪安装槽，当定位台阶面与限位部抵接时，卡爪卡接安装于卡爪安装槽内，且卡爪的自由端与卡爪安装槽相对远离定位台阶面的限位面抵接。插座主体的卡爪卡接设于插针的卡爪安装槽内，且卡爪安装槽安装于插座主体的插针孔内，卡爪和卡爪安装槽的卡接结构为封闭式结构，二者卡接到位后，难以通过对插针或插座主体施加外力的方式、使卡爪脱离卡爪安装槽，锁紧强度更高，卡接连接的稳定性和可靠性更强。
