Abstract

A support for an electrical busbar, made of plastic material, has a recess for holding a busbar. The lower surface of the recess is a resiliently flexible plate supported in the middle by a rib and provided with projections at opposite sides. Adjacent to the mouth of the recess is a resilient detent arm. When a busbar is inserted, it depresses the arm and at least one of the projections by flexing of the plate. The stress in the plate clamps the busbar in the recess, and the arm snaps into place behind the inserted busbar. One of the projections may serve as an end stop for the busbar, if the support is placed at the busbar end. This form of support is easy to manufacture and to use, and provides very reliable clamping and location of the busbar.
