Abstract

本实用新型公开了一种换向片,包括本体部和多个根部,其特征是:所述靠近本体部尾端的根部后端设有斜面,与本体部构成一个钝角。在本实用新型中,由于靠近本体部尾端的根部后端设有斜面,与本体部构成一个钝角,使得本体部尾端在弯钩成型时不易对树脂施力,大大提高了成品率,而且本体部的尾端设有凹槽,排片完的换向片在注塑后,沿着凹槽铣出长槽,使相邻的换向片完全分离而绝缘,排片时无需云母片,节约了成本。

Description

换向片
技术领域
本实用新型涉及一种换向片。
背景技术
目前市场上提供的换向片大都包括一体成型的本体部和多个根部,但在头部弯钩成型时,树脂面容易开裂从而使成品率降低,此外,传统的换向器中的换向片在排片时要实用云母片,并且云母片会一直残留在环形器成品中,增加了成本。
发明内容
鉴于背景技术的不足,本实用新型所要解决的技术问题是提供一种成品率更高且排片时无需云母片的换向片。
    为此,本实用新型提供的换向片包括本体部和多个根部,其特征是:所述靠近本体部尾端的根部后端设有斜面,与本体部构成一个钝角。
所述本体部的尾端设有凹槽。
在本实用新型中,由于靠近本体部尾端的根部后端设有斜面,与本体部构成一个钝角,使得本体部尾端在弯钩成型时不易对树脂施力,大大提高了成品率,而且本体部的尾端设有凹槽,排片完的换向片在注塑后,沿着凹槽铣出长槽,使相邻的换向片完全分离而绝缘,排片时无需云母片,节约了成本。
附图说明
图1为本实用新型的结构示意图;
图2为图1的俯视图。
具体实施方式
如图1和图2所示,本实用新型提供的换向片包括本体部1和多个根部2,靠近本体部1尾端的根部2后端设有斜面3,与本体部1构成一个钝角,本体部1的尾端设有凹槽4。
在本实施例中,由于靠近本体部1尾端的根部2后端设有斜面3,与本体部1构成一个钝角,使得本体部1尾端在弯钩成型时不易对树脂施力,大大提高了成品率,而且本体部1的尾端设有凹槽4,排片完的换向片在注塑后,沿着凹槽4铣出长槽,使相邻的换向片完全分离而绝缘,排片时无需云母片,节约了成本。

Claims (2)

1.一种换向片,包括本体部和多个根部,其特征是:所述靠近本体部尾端的根部后端设有斜面,与本体部构成一个钝角。
2.根据权利要求1所述的换向片,其特征是:所述本体部的尾端设有凹槽。
