Abstract
Abstract A contact blade coupling has a pair of outside members, each member having an integral associated inside member bent along a common edge. The bending of an inside member toward an associated outside member is limited by a spacing protrusion so that inside and outside members are parallel to each other. The inside members are spring contacts and are positioned so as to be prestressed along a line of contact to provide a contact force for holding an intermediate electrical blade connector.

Claim 1
Independent Claim
300 words
A contact blade coupling means for contacting an electrical connector having a generally planar configuration, said coupling means including a terminal comprising: a first pair of generally planar, elongated side members including a first inside member and a first outside member and joined to one another at least along a portion of a first common edge and having first spacing means to limit bending about said first common edge toward one another so that said first pair of side members are substantially parallel to each other; a second pair of generally planar elongated side members including a second inside member and a second outside member joined to one another at least along a portion of a second common edge and having second spacing means to limit bending toward one another so that said second pair of side members are substantially parallel to each other, and so that said first and second pairs of elongated side members are parallel to each other; said first inside and second inside members being spring contacts and positioned in prestressed contact against one another and movable about parallel axes so that there is an increased contact force for holding an intermediate electrical blade connector; a bracer means extending between said first and second inside members, and connected integrally to one of said first and second inside members, so as to provide a barrier to maintain the spacing between said first and second inside members even in the presence of a compressing force; and said bracer means being a tab extending generally perpendicular out from one end of said first inside member, said tab being on one side of said spacing means and said coupling means further comprising a first contact spring surface on the other side of said spacing means on said first inside member.
