Busbar connector for plug-in busways
First Claim
Patent Images
1. In an electrical plug-in busway including at least two elongated track sections connected end-to-end and at least one electrically conducting busbar in each track section for providing electricity to a take-off device installed in the track, the improvement comprising:
- a connector between the ends of adjoining track sections, said connector including an insulating connector body and at least one shunt wire in the insulating connector body with a lug on both ends of the shunt wire, a spreader spring in said connector body adjacent each said lug, and a set screw for wedging each said spreader spring toward the associated lug and thereby pressing the the lugs into spring pressure contact with said busbars in said connected track sections.

a connector between the ends of the adjoining track sections, said connector including an insulating connector body and at least one shunt wire in the insulating connector body with a lug on both ends of said shunt wire in spring pressure contact with said busbars in said connected track sections, and in which said spring pressure is provided by a spreader spring having a generally half-cylinder spring section between flat edge portions. - View Dependent Claims (9)
- 10. A busbar connector for an electrical busway having at least one channel-shaped track section having at least one open end and busbars in opposite sides of the channel-shaped track section for providing electricity to plug-in devices inserted into the track sections, said connector comprising an insulating connector body for insertion into said at least one open end of said track section, at least two insulative spreader extrusions in the connector body, a shunt wire in each said spreader extrusion, each said shunt wire having an electrical contact lug on at least one end thereof projecting from said connector body for contacting one of said busbars in said track section, spreader springs between the shunt wires and a tapered screw for pressing said spreader springs against said shunt wires and said electrical contact on the shunt wires against the busbars in the track sections.
- 15. A busbar connector connecting channel-shaped track sections in an electrical busway, said track sections each having busbars in opposite sides thereof, said connector comprising an insulating connector boy, four parallel insulative spreader members in said connector body, a flexible shunt wire in each spreader member, each shunt wire having an electrical contact lug on both ends thereof projecting outwardly from the connector body, spreader springs in said spreader members on both ends thereof inside said connector body opposite said contact lugs on each shunt wire, and set screws having tapered ends between said spreader springs for pressing said contact lugs against said busbars in said track sections.
- 18. A connector power head assembly for an electrical busway that includes at least one channel-shaped track section having at least one open end with parallel busbars in the channel for receiving plug-in devices, said connector head assembly comprising an insulating connector body for insertion into said at least one open end of said track section, at least two insulative spreader members in said connector body, a shunt wire in each said spreader member, a spreader spring in each said spreader member, a contact lug on one end of each shunt wire projecting outwardly from said connector body opposite said spreader spring and a set screw having a tapered end between said spreader springs for pressing said springs and said contact lugs against said busbars in said track section.
