Abstract
A bus bar assembly includes multiple bus bars, multiple insulating holders, and a housing. Each of the insulating holders is configured to be mounted to one of the bus bars. Each of the insulating holders includes multiple ribs positioned within an interior cavity of the corresponding insulating holder, and the ribs maintain a desired air gap between each insulating holder and the corresponding bus bar mounted in the insulating holder. The housing is configured to receive each of the bus bars and the corresponding insulating holder.
Claims18
An insulating holder for a bus bar, comprising:
- a first surface configured to cover a corresponding first surface of the bus bar, wherein the bus bar has a first terminal, a second terminal, and a conductive strip between the first terminal and the second terminal;
- a second surface configured to cover a portion of a corresponding second surface of the bus bar, wherein the second surface is opposite the first surface;
- a spanning surface extending between the first surface and the second surface;
- a first side surface extending orthogonally from the first surface toward the second surface;
- a second side surface extending orthogonally from the first surface toward the second surface, wherein:
- the second side surface is opposite the first side surface,
- a cavity is defined between the first surface, the second surface, the spanning surface, the first side surface, and the second side surface, and
- the cavity is configured to receive, at least in part, the bus bar;
- and
- a plurality of ribs, wherein each of the plurality of ribs is positioned on either the first surface, the second surface, the spanning surface, the first side surface, or the second side surface facing toward the cavity and wherein the plurality of ribs includes:
- a first rib on the first side surface;
- a second rib on the second side surface;
- a plurality of third ribs on the first surface;
- a plurality of fourth ribs on the second surface, and
- a plurality of fifth ribs on the spanning surface.
