摘要： A brush holder assembly that, by design, cannot be assembly incorrectly is disclosed. The brush holder assembly includes a brush inserted into a brush holder, a block attached to the top of the brush, a spring engaging the block so as to apply radial pressure to the block and brush, and a hook pin engaging the spring and the block so as to hold the spring onto the block. The block includes a semicircular indentation that cradles a coiled portion of the spring. The block also includes a slotted hole for receiving a portion of the hook pin as the block is glued to the top of the brush. The hook pin is preferably a loop terminating at a first end that is a substantially straight pin and terminating at a second end that is a hook-shaped loop in which the straight pin end is inserted. The hook pin is formed from a spring biased metal to facilitate insertion of the straight pin end and into the hook-shaped loop end. Alternatively, a spool assembly can be used to engage the coiled portion of the spring so as to lock it in the indentation in the block. The spool assembly is U-shaped with a first upright end that supports a first spool holder and a second upright end that supports a second spool holder, the first spool holder and second spool holder each engaging and supporting an end of the coiled portion.
摘要翻译：公开了一种根据设计不能组装不正确的电刷架组件。电刷架组件包括插入刷夹中的刷子，附接到刷子顶部的块，与块体接合以便向块和刷施加径向压力的弹簧，以及与弹簧和块接合的钩销以便将弹簧保持在块上。该块包括一个半圆形的压痕，其支撑弹簧的盘绕部分。该块还包括用于在块被胶合到刷子的顶部时接收钩销的一部分的开槽孔。钩销优选为在第一端处终止的环，该第一端是基本上直的销，并且在第二端处终止，该第二端是直插针端插入的钩状环。钩销由弹簧偏压金属形成，以便于直销端插入到钩形环端。或者，可以使用卷轴组件来接合弹簧的卷绕部分，以将其锁定在块中的凹陷中。卷轴组件为U形，其具有支撑第一卷轴保持器的第一直立端和支撑第二卷轴保持器的第二直立端，第一卷轴保持器和第二卷轴保持器各自接合并支撑卷绕部分的端部。
