Abstract
Abstract A current connecting device for establishing electrical connection between rail conductors, having contact clips (20) and division plates (23), the contact clips (20) being modular and comprising two flat electrically conducting coupling pieces (35, 50) which are disposed inside a housing (26) made of insulating material with openings (49) for connection. Each of the coupling pieces has a spring (33, 34) which provide the necessary contact pressure. Each contact clip (20) has an insulating housing (26) in which there is disposed a fixed coupling piece (50) and a coupling piece (35) which can be made maneuverable if desired. Each coupling piece has two contact surfaces (36, 37, 38, 39). Both the division plates (23) and the contact clips (20) are provided with a releasing element (27, 28). The device is a universally applicable current connector with which one can form conductive couplings between electrical conductors, for example copper rails (40), wherever it is desirable. A number of contact clips can be coupled together, all of which can be maneuvered by a common maneuvering element (55) if so desired.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A current connecting clip line of modular construction, for establishing electrical connection between rail-like conductors comprising, at least one contact clip having at least one electrically conducting coupling piece movably maintained within an insulating housing formed so as to completely enclose the at least one coupling piece, said housing including at least one slot for receiving a rail-like conductor and wherein said at least one coupling piece may contact said conductor when said conductor is received in said slot, a coupling stud having two ends and being located generally within said housing and being in operative contact with said at least one coupling piece at one end, and accessible from outside said housing at its other end, said stud being externally movable to adjust the position of said coupling piece relative said slot, so that biasing of said stud effectively insures proper contacting between said coupling piece and the rail-like members.
Claim 2
Dependent Claim
151 words
A current connecting clip line of modular construction, for establishing electrical connection between rail-like conductors comprising, at least one contact clip having at least one electrically conducting coupling piece movably maintained within an insulating housing formed so as to completely enclose the at least one coupling piece, said housing including at least one slot for receiving a rail-like conductor and wherein said at least one coupling piece may contact said conductor when said conductor is received in said slot, a coupling stud having two ends and being located generally within said housing and being in operative contact with said at least one coupling piece at one end, and accessible from outside said housing at its other end, said stud being externally movable to adjust the position of said coupling piece relative said slot, so that biasing of said stud effectively insures proper contacting between said coupling piece and the rail-like members.
Claim 3
Dependent Claim
43 words
A clip line according to claim 1, wherein said coupling stud is preferably made of electrically insulating material and extends somewhat outside the insulating housing and a common maneuvering means on said clip line for simultaneously acting on a plurality of coupling means.
Claim 4
Dependent Claim
33 words
A clip line according to claim 1, wherein said slot includes locking grooves for securely retaining said rail-like member, and wherein said rail-like member includes corresponding tongues to be received by said grooves.
Claim 5
Dependent Claim
23 words
A clip line according to claim 1 including a releasable locking clip on said contact clip for maintaining said clip within said line.
Claim 6
Dependent Claim
48 words
A clip according to claim 1 including first biasing means interposed between said one end of said stud and said coupling piece for biasing said piece toward said slot and to provide resilience between said stud and piece when the rail-like member contacts said piece in said slot.
Claim 7
Dependent Claim
40 words
A clip according to claim 5 including a second biasing means situated to apply a force in a direction opposite of said first biasing means so that the equilibrium position of the stud is determined by the relative bias forces.
Claim 8
Dependent Claim
48 words
A clip line according to claim 1, wherein said at least one coupling piece includes first and second coupling pieces opposing each other across said slot and wherein said second piece includes a raised contact surface of such length that it makes direct contact with said first piece.
Claim 9
Dependent Claim
24 words
A clip line according to claim 7, wherein said second piece includes an extension out of said housing for attachment to an electrical wire.
