Abstract
An electrical junction includes a housing, a screw, and a nut. The housing receives ends of upper and lower busbars, each having a hole along aligned axes. The screw engages both holes and screws into the nut, pressing the busbars together. A cylindrical insulator is inserted into both holes, receiving the screw and inhibiting contact between the busbars and the screw, thereby electrically isolating the busbars from the screw. This configuration enables a secure and insulated electrical connection between the upper and lower busbars.
Claims9
An electrical junction, comprising:
- a housing,
- a screw;
- and
- a nut, wherein the housing is able to receive an end of an upper busbar comprising a first hole along a first axis and an end of a lower busbar comprising a second hole along a second axis aligned with the first axis of the first hole, when busbars are engaged into the housing, both busbars being assembled by the screw engaging both holes and screwing the nut, so as to press busbars one against another, and wherein the junction further comprises a first insulator, generally cylindrical to be inserted in both holes and hollow to receive the screw, in order to inhibit any contact between the busbars and the screw.
A method of assembling an electrical junction, comprising:
- inserting a nut into the bottom of a cylindrical chamber;
- placing and locking a second insulator in the cylindrical chamber;
- inserting an upper busbar into an upper slot of a housing;
- placing a first insulator in the chamber and sliding it to an intermediate position, in order to secure the upper busbar;
- inserting a lower busbar into the lower slot of the housing;
- sliding the first insulator to a final position, in order to secure the upper busbar and the lower busbar;
- and
- inserting a screw into the first insulator and screwing it into the nut.
