1. A DC Bus for use in a power module, the DC Bus comprising:
- (a) a first conductive element comprising;
(i) a first end portion for forming an electrical connection with a substrate;
(ii) a second end portion;
(iii) an intermediate portion situated between the first and second end portions; and
(iv) a compliant portion, deformable between a compressed position and a decompressed position, wherein, when the compliant portion is in the compressed position, the first end portion is biased into physical engagement with the substrate to form an electrical connection with a first contact on the substrate and the second end portion is unbiased and electrically couplable to form a non-pressure engagement electrical connection with a first conductive terminal; and
(b) a second conductive element comprising;
(i) a first end portion for forming an electrical connection with the substrate;
(ii) a second end portion;
(iii) an intermediate portion situated between the first and second end portions; and
(iv) a compliant portion, deformable between a compressed position and a decompressed position, wherein, when the compliant portion is in the compressed position, the first end portion is biased into physical engagement with the substrate to form an electrical connection with a second contact on the substrate and the second end portion is unbiased and electrically couplable to form a non-pressure engagement electrical connection with a second conductive terminal, and wherein the intermediate portions of the first and second conductive elements form positive and negative DC conductor bus plates, respectively, and are substantially parallel to, and separated from, each other.

Abstract
An electrical connector for use in a power module includes a first end portion for forming an electrical connection with a substrate, a second end portion, and a compliant portion situated between the first end portion and the second end portion. The compliant portion includes a compressed position and a decompressed position. The first end portion is configured for forming an electrical connection with a substrate if the compliant portion is in the compressed position.
