Abstract

本实用新型公开了一种钩型换向器的换向铜片,由片体、弯钩部和植入部组成,其特征在于:所述的植入部为倒钩结构,倒钩在片体的内圆面设置,所述的倒钩设有四个,两个上倒钩在靠近弯钩部的左右两侧对称设置,两个下倒钩在远离弯钩部的左右两侧对称设置,上弯钩和下弯钩的钩头相对。上述结构的换向铜片用料省成本低,换向铜片植入换向器模体后与模体的连接强度更高,有效提高钩型换向器的质量。

Description

钩型换向器的换向铜片
技术领域
本实用新型涉及的是一种换向器,具体涉及的是一种钩型换向器的换向铜片。
背景技术
换向器一般分为钩型换向器、槽型换向器和端面换向器三种,传统的钩型换向器,它的换向铜片的植入部一般采用的是燕尾结构,换向铜片通过燕尾植入换向器的模体,两者的连接强度较弱,在某些工作场合换向铜片容易脱落,直接影响换向器产品质量,而且燕尾结构的换向铜片用料多,生产成本高。
发明内容
鉴于目前公知技术存在的问题,本实用新型要解决的技术问题是在于提供一种用料省成本低,与模体连接强度高的钩型换向器的换向铜片。
本实用新型是采取如下技术方案来完成的:
钩型换向器的换向铜片,由片体、弯钩部和植入部组成,其特征在于:所述的植入部为倒钩结构,倒钩在片体的内圆面设置,所述的倒钩设有四个,两个上倒钩在靠近弯钩部的左右两侧对称设置,两个下倒钩在远离弯钩部的左右两侧对称设置,上弯钩和下弯钩的钩头相对。
本实用新型的有益效果是:换向铜片的植入部采用了倒钩结构,它通过四个倒钩与换向器的模体形成牢固连接,无论在什么工作场合,换向铜片都不易脱落,大大提高了钩型换向器的产品质量;另外,换向铜片的四个倒钩外形小,结构简单,用料较省,而且可以与换向铜片一起通过冲压完成,成本低。
附图说明
本实用新型有以下附图:
图1为本实用新型的结构示意图;
图2为本实用新型在连体时的状态图;
图3为图2的仰视图。
具体实施方式
参照附图1、2、3,该种钩型换向器的换向铜片,由片体1、弯钩部2和植入部组成,片体1具有内圆面和外圆面,所述的植入部为倒钩结构,倒钩在片体1的内圆面设置,所述的倒钩设有四个,两个上倒钩3在靠近弯钩部2的左右两侧对称设置,两个下倒钩4在远离弯钩部2的左右两侧对称设置,上弯钩3和下弯钩4的钩头相对,上弯钩3和下弯钩4的钩头分别向内弯曲形成C字型结构。
