Abstract
A brush lead guide for a brush holder assembly configured to retain the leads extending from a brush in a desired position/orientation to ensure the leads do not interfere with movement of the brush within the brush holder. In some instances, the lead guide includes a first guide rail including a channel for receiving a first lead of the brush and a second guide rail including a channel for receiving a second lead from the brush. The lead guide maintains the leads in a position such that the leads are held within the width of the opening of the brush holder to ensure the leads do not interfere with movement of the brush within the brush holder during use of the brush holder assembly.
Claims26
A lead guide for maintaining the leads extending from a brush of a brush holder assembly in a desired position, the lead guide comprising:
- a bracket comprising a first guide rail, a second guide rail, and a cross member extending between the first guide rail and the second guide rail;
- the first guide rail including a channel for receiving a first lead from the brush and the second guide rail including a channel for receiving a second lead from the brush, the bracket configured to space the first lead away from the second lead to permit a spring of the brush holder assembly to be positioned therebetween;
- wherein the first lead extends from opposite ends of the channel of the first guide rail;
- and
- wherein the second lead extends from opposite ends of the channel of the second guide rail.
A brush holder assembly for an electrical device, the brush holder assembly comprising:
- a brush holder;
- a brush positionable in the brush holder, the brush including a first lead extending from the brush and a second lead extending from the brush;
- and
- a lead guide positionable between the first lead and the second lead, the lead guide comprising a bracket having a first guide rail, a second guide rail, and a cross member extending between the first guide rail and the second guide rail;
- wherein the lead guide is configured to travel with the brush relative to the brush holder as the brush diminishes in length during use;
- wherein the lead guide is configured to prevent the first lead and the second lead from contacting the brush holder and restricting free movement of the brush in the brush holder;
- wherein the lead guide is removable from the brush while the first lead and the second lead remain secured to the brush.
A lead guide for maintaining the leads extending from a brush of a brush holder assembly in a desired position, the lead guide comprising:
- a bracket comprising a first guide rail, a second guide rail, and a cross member extending between the first guide rail and the second guide rail;
- the first guide rail including a channel for receiving a first lead from the brush and the second guide rail including a channel for receiving a second lead from the brush, the bracket configured to space the first lead away from the second lead to permit a spring of the brush holder assembly to be positioned therebetween;
- wherein the channel of the first guide rail opens out in a first direction and the channel of the second guide rail opens out in a second direction, opposite the first direction.
A brush holder assembly for an electrical device, the brush holder assembly comprising:
- a brush holder;
- a brush positionable in the brush holder, the brush including at least one lead extending from an upper surface of the brush, such that the at least one lead extends through an upper opening of the brush holder;
- a lead guide coupled to the at least one lead;
- and
- a spring including a coiled portion positioned over the upper surface of the brush when the brush is positioned in the brush holder, the spring being configured to exert a force against the brush in the brush holder;
- wherein the lead guide is configured to travel with the brush relative to the brush holder as the brush diminishes in length during use;
- wherein the lead guide is configured to prevent the at least one lead from contacting the brush holder and restricting free movement of the brush in the brush holder;
- wherein the lead guide is positioned between the at least one lead and the coiled portion of the spring to prevent the at least one lead from directly contacting the coiled portion of the spring.
