Technical Problem

[0003]但现有的一种三相异步电动机接线盒,在公开专利中(公开号:CN208797748U)包括盒体,盒体固定到电机壳的接线端口处,盒体上开有矩形开口,矩形开口处设有与之相适配的橡胶密封盖,橡胶密封盖外设有金属框,紧固螺钉通过金属框将橡胶密封盖压紧到盒体上,虽然该实用新型能实现电动机内部线路与外线连接,并克服了传统结构接线盒进线困难的弊端,结构简单,密封性好,方便接线操作,开孔大小、数量可以自由选择,实现了动力电缆的方便引入,具有绝缘、阻隔、及保护接线柱的作用,但是该实用新型对线缆的固定效果一般,在线缆受到外力拉扯或晃动时可能会导致接线处接触不良,致使连接稳定性欠佳,并且该实用新型在接线时还需要根据线缆的粗细进行开孔操作,这势必会导致接线工作比较繁琐复杂,费时费力,不够方便接线

Benefits of technology

[0011]与现有技术相比,本实用新型的有益效果是:通过一根或者多跟线束穿过固定装置进入到接线盒的内部后与接线柱连接,固定装置将线束固定,防止拉扯使线束与接线柱分离,提高接线的稳固性。
