Abstract

A contact and busbar assembly forms a bus system on electronics housings arranged in an array direction. Each housing includes a circuit board. The contact and busbar assembly includes multiple bus plugs having first connecting contacts for electrically contacting the circuit boards and second connecting contacts in the form of socket contacts for electrically contacting power rail strips. A plurality of power rail strips electrically connects the second connecting contacts of adjacent electronics housings. A first power rail strip electrically connects the bus plugs of two directly adjacent electronics housings and a second power rail strip of greater length electrically connects two spaced electronics housings. An electronics housing assembly is provided having multiple electronics housings arranged against one another in the array direction and a contact and busbar assembly as set forth above. A method for removing or replacing an electronics housing arranged between two adjacent electronics housings of such an electronics housing assembly is also provided.

First claim

What is claimed is:

1. A contact and busbar assembly for forming a bus system on a plurality of electronics housings each including a circuit board and being arranged adjacent one another in an array direction, comprising
(a) a plurality of bus plugs connected with the electronics housings, each bus plug having first connecting contacts for electrically contacting the circuit boards and second connecting contacts; and
(b) a plurality of power rail strips for electrically connecting said second connecting contacts of said bus plugs of the electronics housings, at least one first power rail strip of said plurality of power rail strips electrically connecting said bus plugs of two directly adjacent electronics housings and at least one second power rail strip of greater length than a length of said at least one first power rail strip for electrically connecting said bus plugs of two of the electronics housings which are spaced from each other in a non-adjacent arrangement.

2. The contact and busbar assembly as claimed in claim 1 , characterized wherein the length of the at least one second power rail strip is longer than the length of the at least one first power rail strip by a distance corresponding with a width of at least one electronics housing.

3. The contact and busbar assembly as claimed claim 1 , wherein said power rail strips each have a connecting portion on the opposite ends thereof, a connecting length of which corresponds to approximately half of a connecting width of a second connecting contact of the bus plug.

4. The contact and busbar assembly as claimed in claim 1 , and further comprising a feed power rail strip having an extended connecting portion.

5. The contact and busbar assembly as claimed in claim 4 , wherein a connecting length of the extended connecting portion of said feed power rail strip corresponds with a connecting width of said second connecting contact of said bus plug.

6. An electronics housing assembly comprising a plurality of electronics housings arranged against one another in an array direction and a contact and busbar assembly as claimed in claim 1 .

7. A method for removing or replacing a selected electronics housing arranged between two adjacent electronics housings of an electronics housing assembly on either side of the selected electronics housing as claimed in claim 6 , wherein said bus plug of the selected electronics housing is connected with said bus plugs of other electronics housings of the electronics housing assembly by first and second power rail strips, comprising the steps of
(a) removing said first and second power rail strips which connect the selected electronics housing to the other electronics housings, respectively;
(b) removing the selected electronics housing from the electronics housing assembly; and
(c) connecting said bus plugs of the other electronics housings to one another by a third power rail strip having a length eater than said first power rail strip.

8. The method as claimed in claim 7 , wherein the length of said third powder rail strip is computed from the total of the lengths of said removed power rail strips plus the electronics housing width of the selected electronics housing.
