Description

钩型换向器铜片
【技术领域】
本实用新型涉及一种换向器,具体涉及一种钩型换向器的铜片。 
【背景技术】
钩型换向器是所有换向器产品中占比最大的一种,钩型换向器因其顶部具有弯钩而得名。钩型换向器的主要零件是钩型铜片,钩型铜片通过其内侧面设有的固定脚与换向器基体固定在一起,固定脚起到加强与基体之间的结合力的作用。目前的钩型换向器铜片,固定脚不外乎采用的是勾脚、燕尾或肋板结构,上述结构固定脚与基体材料的结合力不是很强,对于一些钩型换向器产品来说会影响到产品的机械强度和超速性能,进而影响产品质量。 
【发明内容】
鉴于背景技术的不足,本实用新型的目的旨在提供一种应用于钩型换向器产品,能有效提高钩型换向器产品机械强度和超速性能的钩型换向器铜片。 
本实用新型是采取如下技术方案来完成的: 
钩型换向器铜片,包括片体、弯钩和固定脚,弯钩设于片体的顶部,固定脚设于片体的内侧,其特征在于:固定脚由带连续矩形齿的左右板体组成,板体高度与片体高度相当,板体为直角折弯件,所述矩形齿位于板体的内折弯面上,板体的外折弯面与所述片体的侧边相连接,左右板体与所述片体之间围成换向器基体材料的填充空间。 
上述技术方案的钩型换向器铜片,其固定脚完全不同于现有技术,固定脚 采用了C型包围结构,同时矩形齿中间留出让换向器基体材料充分进入铜片内部空间的矩形齿槽,从而使钩型铜片与基体之间能够形成牢固的结合,有效提高钩型换向器产品的机械强度和超速性能,更好满足一些钩型换向器产品的使用要求。 
作为优选,左右板体的矩形齿相对设置并上下错开。 
【附图说明】
本实用新型有如下附图: 
图1为本实用新型的背面方向视图, 
图2为图1的A-A剖视图, 
图3为图1的俯视方向视图。 
【具体实施方式】
如图所示,本实用新型的钩型换向器铜片,包括片体2、弯钩1和固定脚,弯钩1设于片体2的顶部,固定脚设于片体2的内侧,所述固定脚由带连续矩形齿4的左右板体3组成,板体3高度与片体2高度相当,板体3为直角折弯件,所述矩形齿4位于板体3的内折弯面上,板体3的外折弯面与所述片体2的侧边相连接,左右板体3与所述片体2之间围成换向器基体材料的填充空间5,左右板体3的矩形齿4相对设置并上下错开。
