Abstract
Electrical connection apparatus is disclosed for achieving versatile connections between bus boards and electrical devices having conductive pins which extend through holes in the boards. Connections are achieved through transversely expansible conductive washers within the holes around the pins. Transverse expansion is caused by compression of individual washers along central axes of the holes, the compression being produced by expander means associated with the washers. Two expansible washer configurations are disclosed, one comprising spring material preformed with protuberances which are flattened to cause transverse expansion, and the other comprising a conductive elastomeric material.
Claims16
In electrical apparatus of the type including at least one bus board for supplying electrical potential to a component having a conductive pin which extends through a hole in the board along a central axis of the hole, the hole being at least partially bounded by a conductive surface, an improved connection device comprising:
- a transversely expansible conductive washer sized to permit positioning thereof around the conductive pin within the hole in the bus board, compression of said washer along the axis of the hole causing transverse expansion of said washer;
- and
- expander means for compressing said washer between a pair of surfaces transverse to the axis of the hole, thereby transversely expanding said washer to achieve electrical connection between the board and the pin.
Electrical circuit apparatus including an improved system for supplying electrical potentials from bus boards to circuit devices through connectors having conductive pins which extend through holes in the boards along central axes of the holes, said circuit apparatus comprising:
- a multilayer bus board assembly including a plurality of bus boards insulated from one another and each carrying an electrical potential, said bus board assembly having holes therethrough transverse to the planes of the boards for accepting conductive pins of electrical device connectors, the holes in each board being at least partially bounded by conductive surfaces;
- a plurality of transversely expansible conductive washers, each interposed between a predetermined conductive pin and a conductive surface bounding a hole in a predetermined bus board, compression of said washers along the axes of the holes causing transverse expansion of said washers to achieve separate electrical connections between said predetermined boards and pins respectively;
- and
- expander means associated with each of said washers for compressing said washers betwen pairs of surfaces transverse to the axes of the holes to provide for transversely expanding said washers.
