Abstract
Abstract A jumper strip for terminal blocks or the like comprises in one embodiment a pair of fastener engaging portions coupled together by a resiliently deflectable upstanding arched portion so that the spacing between the apertures may be selectively varied by exerting suitable pressure on the arched portion. The strip may be disposed over terminal screws having a center to center spacing slightly greater or smaller than the spacing between the apertures in the strip whereby upon release of the arched portion the strip is urged against the shank of the terminal screws and retained in position during the loosening and tightening of the screws. In another embodiment, a plurality of such fastener engaging portions are resiliently joined one to another in strip fashion to provide a multiple terminal shorting bar or jumper strip. The apertures are joined to a common edge of the jumper strip by a slot which may be aligned with or offset from the axis of the aperture.

Claim 1
Independent Claim
263 words
A deflectable jumper strip comprising: a body member formed from generally flat, resilient metallic stock, said body member having a pair of generally flat fastener engaging portions lying in a common first plane and coupled together by at least one resiliently deflectable upstanding arched portion having sides extending generally parallel to a second plane which is disposed substantially perpendicular to said first plane, said arched portion being disposed intermediate said fastener engaging portions, there being an aperture extending transversely through each of said fastener engaging portions, said apertures having centers spaced a first given distance from one another when said arched portion is in an undeflected state, and a second given distance from one another when said arched portion is selectively deflected, there being a slot joining each of said apertures with a common edge of said jumper strip, the axis bisecting each of said slots and lying in said first plane being selectively offset from an axis parallel to said slot bisecting axis and passing through the center of a corresponding one of said body member apertures and lying in said first plane so that by selectively deflecting said body member arched portion, said slots may be aligned with and cooperatively coupled to terminals disposed on centers spaced from one another a distance generally equivalent to said first given distance, wherein upon the release of said arched portion, said apertures are caused to be aligned with and cooperatively coupled to such terminals, said slots thereby restricting the removal of said jumper strip from such terminals prior to redeflection of said arched portion.

Claim 3
Dependent Claim
30 words
A deflectable jumper strip as defined in claim 1 wherein the center to center distance between said aperture is less than the center to center distance between said corresponding slots.
Claim 4
Dependent Claim
23 words
A deflectable jumper strip as defined in claim 1 wherein said fastener engaging portions are coupled together by two of said arched portions.
