Technical Problem

[0003]现有针对漆包线出线端大多通过绝缘支架外侧上的凸台限位进行走线,而随着漆包线线径的增大,走线过程中线径变粗的漆包线无法完全与绝缘支架外壁贴合,造成漆包线外围走线易松动,漆包线状态松垮,活线与相邻相线圈接触造成异相接触,同时松散的漆包线在运行时还会产生明显的晃动,进一步加剧线材的磨损和老化,甚至出现漆包线飞出而导致散线的不良情况,在一定程度上存在安全隐患

Benefits of technology

[0018]本实用新型提供一种电机漆包线固定装置,其中,电机包括定子铁芯、绕组线圈与绝缘支架,定子铁芯沿自身圆周方向交替设有定子齿与定子槽,绕组线圈包括多个漆包线绕组,漆包线绕组缠绕于定子齿上而使其末端形成出线端,绝缘支架嵌接于定子槽内以分隔漆包线绕组与定子齿,电机漆包线固定装置包括卡接组件与多个套管,多个套管与多个漆包线绕组一一对应,且套管包裹于出线端,卡接组件凸设于绝缘支架的外侧壁,卡接组件用于卡接包裹出线端的套管。如此设置,增设套管套设且包裹于出线端,以对活动的出线端起到绝缘作用,防止异相接触的安全风险,同时结合卡接组件,进一步增强了对于出线端的夹持定位效果,保证其走线的稳定性与可靠性,即便电机在长期运行或强烈振动下,出线端也不会发生径向跳动或轴向滑移,避免因出线端松动而带来的电气故障,从而有效提升电机的绝缘性能及安全性。

Abstract

The utility model relates to motor technical field, specifically disclose a motor enameled wire fixing device, wherein, the stator core alternately has stator tooth and stator slot along the self circumferential direction, the enameled wire winding is wound on the stator tooth and makes its end form the outgoing terminal, the insulating support is inlayed in the stator slot to separate enameled wire winding and stator tooth, a plurality of bushings and a plurality of enameled wire winding one to one, and the bushing is wrapped in outgoing terminal, and the clamping assembly is protruding in the lateral wall of insulating support, and is used for clamping bushing that wraps outgoing terminal. Add bushing and wrap in outgoing terminal, to play the insulation effect to the movable outgoing terminal, prevent the security risk of heterophase contact, combine clamping assembly simultaneously, further enhance the clamping positioning effect for outgoing terminal, guarantee its stability and reliability of wiring, avoid the electrical fault that outgoing terminal loosens brings, thereby effectively improve the insulation performance and security of motor.
