US 9,190,791 B1 · Electrical busway splice connector

Abstract

A splice connector for a busway system utilizes individual connectors made of a conductive material and having a u-shaped cross-section that fit over ends of a pair of busbars to be connected to each other, and within which are mounted multi-contact louvers that extend the length of the connectors to establish a low impedance electrical connection between the connector and the respective busbars. The louvers are secured in place by a dovetail groove that retains the louvers within the connectors and causes the individual contact sections of the louvers to bow outwardly so as to press against the busbars when the connector is fitted over the busbars. The connectors are snapped into insulative housing halves or sections that align the connectors with the busbars, and that provide isolation between horizontally aligned pairs of connectors. A planar insulator board provides separate between vertically-aligned pairs of busbars when the connectors are fitted over the busbars and the insulative housing sections are aligned and secured to each other. Spacers may be utilized to enable different sized u-shaped connectors to fit within a standard insulative housing.

Dependent claims

A connector for use in electrically connecting a pair of busbars extending from different busway sections, the busbars being axially aligned and having facing end surfaces, comprising:

an electrically conductive elongated connector member having a generally u-shaped cross-section into which respective ends of the pair of busbars are fitted;
and
a pair of electrically conductive multi-contact louvers,
wherein parallel sidewalls of the electrically conductive elongated connector member include dovetail grooves into which the louvers are fitted such that respective side edges of the louvers extend into dovetail portions of the grooves, said dovetail portions retaining the louvers, and
wherein the width of the louvers exceeds a width of the grooves to cause the individual contact sections of the louvers to bow outward away from the surface of the groove to pressingly engage surfaces of the busbars when the busbars are inserted into the electrically conductive elongated connector member.

A splice assembly for joining two busway sections of a busway system and for electrically connecting individual pairs of busbars extending from each of the busway section, the individual pairs of busbars being axially aligned and facing end surfaces, comprising:

at least four electrically conductive elongated connector members having a generally u-shaped cross-section, each electrically conductive elongated connector member including a pair of louvers extending along respective sidewalls of the elongated members;
a pair of insulative housing sections, each said housing section including two sidewalls connected to a top/bottom wall extending transversely between the sidewalls, and an isolating wall extending transversely from the top/bottom wall midway between the two sidewalls to form two longitudinally-extending compartments, said compartments each being arranged to receive and hold respective ones of the electrically conductive elongated connector members, and said isolating wall electrically insulating an electrically conductive elongated connector member in a first one of the compartments from an electrically conductive elongated connector member in a second one of the compartments;
and
a planar insulator extending between a first pair of electrically conductive elongated connector members in one of the insulative housing sections and a second pair of electrically conductive elongated connector members in a second one of the insulative housing sections,
wherein said splice assembly is assembled to said busbars by fitting said electrically conductive elongated connector members over axially aligned pairs of said busbars and fastening said insulative housing sections to each other to capture said busbars and the planar insulator, in order to correct an antecedent base issue, within a completed housing formed by said two insulative housing sections.
