Abstract
Abstract An electrical power connector for PC boards or bus bars having low insertion force and low voltage drop across the connector. The connector features a female receptacle having a double set of opposing rows of multipoint spring contacts mating with a two-tiered male plug. The spring contacts make electrical contact to the tiers of the male plug.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
An electrical power connector comprising a coacting mating plug and female receptacle, the male plug comprising a blade having first and second thickness tiers with a rounded front end and a rounded shoulder transition between the tiers, the trailing edge of the blade extending from one surface of the second tier and adapted for delivery of electrical power, the female receptacle comprising a bar of conductive material having a first and second pair of parallel rows of multipoint spring contacts, the first row pair adapted to mate with the first tier of the mating male plug, the second row extending past the first row and adapted to mate with the second tier of the male plug portion.
Claim 2
Dependent Claim
117 words
An electrical power connector comprising a coacting mating plug and female receptacle, the male plug comprising a blade having first and second thickness tiers with a rounded front end and a rounded shoulder transition between the tiers, the trailing edge of the blade extending from one surface of the second tier and adapted for delivery of electrical power, the female receptacle comprising a bar of conductive material having a first and second pair of parallel rows of multipoint spring contacts, the first row pair adapted to mate with the first tier of the mating male plug, the second row extending past the first row and adapted to mate with the second tier of the male plug portion.
Claim 3
Dependent Claim
35 words
The connector of claim 1 wherein the spacing between first row of multipoint spring contacts and second row of multipoint spring contacts is greater than the width of the first tier of the male plugs.
