Abstract: An electrical bus bar assembly includes a first bus bar segment, a second bus bar segment separated from the first bus bar segment, and a first plurality of bearings formed of an electrically conductive material and in electrical contact with the first bus bar segment and the second bus bar segment. The first plurality of bearings is configured to allow the first bus bar segment to move relative to the second bus bar segment. A method of manufacturing such an electrical bus bar assembly is also provided.

Abstract: Electrical connectors coupleable through an aperture in a substrate are described. According to various embodiments, an electrical connector includes an upper mounting unit and a lower mounting unit. The upper mounting unit includes a first surface that engages with a first planar surface of the substrate, and a second surface that engages with a second surface of the substrate arranged substantially perpendicular to the first planar surface. The lower mounting unit is coupleable to the upper mounting unit through the aperture and engages with a third planar surface of the substrate opposed to the first planar surface of the substrate to secure the electrical connector in the aperture.

Abstract: An electrical connector includes a pair of electrical contacts between which two electrical bus bars are received. Each electrical contact in the pair of electrical contacts having a central base, a first plurality of contact fingers extending longitudinally from the base, and a second plurality of contact fingers extending from the base in the opposite direction. The electrical connector also includes a spring assembly having a retaining band configured to secure the pair of electrical contacts within the electrical connector. The spring assembly further has a first plurality of spring fingers extending longitudinally from the retaining band in the first direction, and a second plurality of spring fingers extending longitudinally from the retaining band in the second direction. A spring finger of the first or second plurality of spring fingers is in compressive contact with at least one contact finger of the first and second plurality of elongate contact fingers.
