插座防脱技术研究与应用

防脱插座是一种插头在锁定状态下可方便插入不易拔出，解锁状态下又能容易拔出的插座，这在某些场合可有效防止用电设备因掉电引起的事故或危害。本文根据设计要求分析了插座防脱的各种技术方案，阐述了实施例中的关键技术、自锁原理、设计计算以及结构设计中的难点和解决办法，为防脱插座的产品设计提供了理论基础。

Research and Application of Self-locking Technology of Socket

Self-locking socket could prevent plug being pulled out at the locking mode, and the plug would be pulled out normally at its unlocking mode. In a certain occasion, this kind of socket could reduce the dangerous accident effectively by preventing running equipment sud- denly being power off due to loosen power connection. In this paper, it analyzes several solu- tions for self-locking socket, elaborates the key technology, self-locking principle, theoret ical calculation as well as the difficulties on design requirement. It provides the theory and technical solution of structure design based basis for products design.
