Devices and methods of use for brush holder assemblies are disclosed. Brush holder assemblies including a mounting block and a brush holder are disclosed. Also illustrated is a brush holder assembly including a first portion in sliding engagement with a second portion. In some embodiments the brush holder includes a channel, such that at least a portion of the mounting block is disposed within the channel of the brush holder.

A receptacle cleaning assembly for use with electrical connectors includes a receptacle washing fixture having a manifold body with a solution inlet and outlet. A plurality of nozzles, in communication with the solution inlet, are coupled with the manifold body and are arranged in a pattern corresponding to female connector receptacles. An interface seal is coupled with the manifold body. The plurality of nozzles extend through the interface seal, and the interface seal is configured to seal along a face of the connector. At least one solution return passage extends through the interface seal from an exterior of the plurality of nozzles to the solution outlet. An alignment skirt extends from the manifold body, and couples and aligns the connector receptacles with the plurality of nozzles. In another example, the receptacle cleaning assembly includes a receptacle brush fixture including a plurality of reciprocating brushes for use in the female connector receptacles.

A method for producing a shaft grounding ring includes providing a shaft grounding ring having an annular main body and contact elements arranged on the main body. The contact elements are electrically conductive and plastic-based. The contact elements are configured to establish an electrically conductive sliding contact with a circumferential surface of a shaft or of a sleeve placed onto the shaft. The contact elements are elastically bendable such that the contact elements are configured to preload the electrically conductive sliding contact. Additionally, the method includes thermally preconditioning the shaft grounding ring before use.
