Patent

CA 2443331

A neutral bar assembly is provided which includes a plurality of neutral bars electrically and structurally secured together with a pair of expanders. Each of the expanders is a unitary member made of an electrically conductive material, having a plurality of forwardly extending legs. Each of the legs fits into one of the bores of one of the neutral bars of the assembly and is secured therein with one of the wire-binding screws of one of the neutral bars. The neutral bar assembly of this invention overcomes the deficiencies in the prior art by electrically and structurally connecting several neutral bars in a compact, efficient and cost-effective manner without increasing the size of the assembly. The invention also allows for proper placement and torque application to wire-binding screws securing wires in the variously sized bores.

L'invention concerne un ensemble de barres neutres, qui comprend une série de barres électriquement neutres et fixées ensemble en une structure à l'aide d'une paire d'extendeurs. Chacun de ces extendeurs est un membre solidaire fait d'un matériau électriquement conducteur, muni de plusieurs pattes orientées vers l'avant. Chaque patte entre dans un des trous de l'une des barres neutres de l'ensemble et y est fixée par une des vis serre-fils de l'une des barres neutres. L'ensemble des barres neutres de cette invention surmonte les lacunes de l'état de la technique en raccordant électriquement et structurellement plusieurs barres neutres de manière compacte, efficace et rentable sans augmenter les dimensions de l'ensemble. L'invention permet également un emplacement et le serrage appropriés des fils d'acier des vis serre-fils dans des trous de dimensions diverses.
