Abstract

The invention relate to a bus bar holder having a bottom part and a top part detachably connected to the bottom part, between which, when they are connected together, at least one busbar passage is formed, wherein the top part and the bottom part have, on mutually opposite contact surfaces, sliding faces along which they bear against one another and are movable between an open position, in which the top part can be lifted off the bottom part, and a closed position, in which the top part is secured to the bottom part via a tongue-and-groove connection, wherein a releasable latching pawl secures the top part and the bottom part in the closed position. Also described is a corresponding arrangement made up of at least one such busbar holder and at least one busbar.

First claim

The invention claimed is:

1. A busbar holder comprising a bottom part and a top part detachably connected with bottom part, between which, if they are connected with each other, at least one busbar passage is formed, wherein the top part and the bottom part have sliding faces on opposite support sides along which they bear against one another between an open position in which the top part can be lifted from the bottom part and a closed position in which the top part is mounted to the bottom part through a tongue-and-groove connection, the top part and bottom part being displaceable relative to each other, wherein a releasable latching pawl mounts the top part and the bottom part in the closed position, the releasing mounting pawl being located on a central portion of the support side of the bottom part, and wherein the bottom part has a mounting side opposite its support side for mounting of the bottom part on a base, wherein a screw channel extends between the support side and the mounting side of the bottom part and wherein a positioning pin projects from the screw channel and protrudes over the mounting side.

2. The busbar holder according to claim 1 , wherein the tongue-and-groove connection is formed as at least one T-shaped or L-shaped projection that extends from the support side of the part of top part and bottom part having the T-shaped or L-shaped projection.

3. The busbar holder according to claim 2 , in which the T-shaped or L-shaped projection extends into a recess of the respective other part of top part and bottom part, wherein the T-shaped or L-shaped projection in the closed position grips from behind an undercut of recess, and wherein the T-shaped or L-shaped projection in the open position is isolated relative to undercut.

4. The busbar holder according to claim 2 , in which the part of top part and bottom part having recess have on an outer side a passage that opens into the undercut.

5. The busbar holder according to claim 1 , in which the releasable latching pawl projects from a first of the two opposite support sides and in the closed position is received in a latching receptacle in a second of the two opposite support sides.

6. The busbar holder according to claim 5 , in which the part of top part and bottom part having the latching receptacle on an outer side has a tool insertion opening that opens into latching receptacle.

7. The busbar holder according to claim 1 , in which positioning pin is mounted detachably in mounting side and preferably mounted through a predetermined breaking point.

8. The busbar holder according to claim 7 , in which positioning pin is mounted through a predetermined breaking point on the inner circumference of an annular flange, which is arranged inside screw channel bordering on mounting side and preferably aligned with mounting side.

9. The busbar holder according to claim 1 , in which the top part on its outer side for each busbar receptacle has a mark identifying the position of busbar receptacle.

10. The busbar holder according to claim 1 , in which the cross-section of the at least one busbar passage is formed by the cross-section of a busbar receptacle in bottom part, wherein busbar receptacle is closed by support side of top part if top part and bottom part are connected with each other.

11. An arrangement of a busbar holder according to claim 10 and a busbar that is inserted into the busbar receptacle in bottom part, wherein an outer profile side of busbar aligns with sliding face of bottom part and rests on sliding face of top part if top part and bottom part are connected with each other.

12. A busbar holder comprising:
a bottom part and a top part detachably connected together forming a busbar passage;
the bottom part having a support side engaging the top part, the bottom part further including a mounting side opposite the support side for mounting to a base;
the bottom part further including first and second screw channels adjacent to each other and extending from the support side to the mounting side;
a detachable positioning pin in the first screw channel protruding from the mounting surface; and
the positioning pin being configured to engage a hole in the base to assist in aligning the second screw channel with another hole in the base such that a screw can extend the through the second screw channel and into the base, with the positioning pin thereafter being detachable so that another screw can extend through the first screw channel and into another hole in the base after the positioning pin has been removed.

13. The busbar holder of claim 12 wherein the positioning pin is configured to be broken away.
