1)为了防止蛇形管松脱，底座13a与压片2a之间的压力需要很大才能将蛇形管压紧，但容易将蛇形管压扁；
2)由于筒体部10a的内表面和蛇形管的外表面都是光滑的，摩擦力小，底座13a与压片2a之间的压力不足时蛇形管容易被拔出；
3)由于通孔11a里面没有定位结构且通孔11a的直径比蛇形管的外径大，蛇形管很难定位，且蛇形管很容易伸入到电机机壳内部将定子绕组破坏。
发明内容：
为了克服现有技术的缺陷，本实用新型的目的是提供一种护线套组件及其应用的电机，即不会因压力过大而导致蛇形管被压扁，也不会因压力过小而导致蛇形管容易从接头中松脱，同时对蛇形管的安装能起到定位的作用，能有效防止蛇形管伸入到电机机壳内部将定子绕组刮伤。
