Abstract
Abstract High pressure electrical contacts are provided coated with a deformable ductile white metal, for example, white metals selected from the group consisting of Sn, Pb, Cd, Zn, Bi, In, alloys of at least two of these metals with each other and alloys of at least one of these metals with Sb. The coating metal advantageously provides an easily separable and reusable low contact resistance junction at low loads when the coated male member of the contact is in electrical contact with an electrically conductive element siliarly coated, whereby the two coatings mutually deform one into the other to provide a gas tight contact at the region of coating deformation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
In combination in an electrical connector for effecting multiple, readily separable low energy, signal level connections, comprising a plug contact connector characterized by a plurality of extending spring elements, each having a male contact point, said elements and said contact points being made of an electrically conductive metal coated with a layer of a deformable white metal, and a receiving member comprising a substrate having thereon a plurality of electrically conductive elements made of an electrically conductive metal, said elements being also coated with a deformable ductile white metal, said plug connector with said coated male contact points being adapted to effect a separable spring-loaded contact connection with said coated elements of said receiving member, such that when the said plurality of male contact points is in spring-loaded penetrating contact against the coated elements of said receiving member, the white metal coatings at the area of contact are mutually plastically deformed at the point of contact, to provide a low resistance contact between the coated male contact points and the said coated electrically conductive elements.
Claim 2
Dependent Claim
175 words
In combination in an electrical connector for effecting multiple, readily separable low energy, signal level connections, comprising a plug contact connector characterized by a plurality of extending spring elements, each having a male contact point, said elements and said contact points being made of an electrically conductive metal coated with a layer of a deformable white metal, and a receiving member comprising a substrate having thereon a plurality of electrically conductive elements made of an electrically conductive metal, said elements being also coated with a deformable ductile white metal, said plug connector with said coated male contact points being adapted to effect a separable spring-loaded contact connection with said coated elements of said receiving member, such that when the said plurality of male contact points is in spring-loaded penetrating contact against the coated elements of said receiving member, the white metal coatings at the area of contact are mutually plastically deformed at the point of contact, to provide a low resistance contact between the coated male contact points and the said coated electrically conductive elements.
Claim 3
Dependent Claim
39 words
