Abstract
Abstract A strip-shaped longitudinal rib forces the clip projection of a conductive foil provided for connection out of the plane of its carrying surface. Given contact pressure of the contact springs of a spring strip the clip projection molds against the strip-shaped longitudinal rib and is clamped between the latter and the spring strip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A method for automatic contacting of a conductive foil lying against a carrying surface to a spring strip, wherein at least one side of a clip projection connected to the conductive foil comprises a plurality of electrical contact surface to which individual contact springs of the spring strip are respectively allocated; comprising the steps wherein the clip projection of the conductive foil is first applied against the strip-shaped longitudinal rib, which is arranged at a fixed position relative to the carrying surface and which is forcing the clip projection out of the plane of the carrying surface, the conductive foil is then secured on the carrying surface in that, subsequently, the clip projection is clamped between the strip-shaped longitudinal rib and the contact springs of the spring strip, whereby the clip projection engages against said strip-shaped longitudinal rib upon contact pressure of the contact springs.
Claim 2
Independent Claim
145 words
A method for automatic contacting of a conductive foil lying against a carrying surface to a spring strip, wherein at least one side of a clip projection connected to the conductive foil comprises a plurality of electrical contact surface to which individual contact springs of the spring strip are respectively allocated; comprising the steps wherein the clip projection of the conductive foil is first applied against the strip-shaped longitudinal rib, which is arranged at a fixed position relative to the carrying surface and which is forcing the clip projection out of the plane of the carrying surface, the conductive foil is then secured on the carrying surface in that, subsequently, the clip projection is clamped between the strip-shaped longitudinal rib and the contact springs of the spring strip, whereby the clip projection engages against said strip-shaped longitudinal rib upon contact pressure of the contact springs.
Claim 3
Dependent Claim
88 words
A method for automatic contact according to claim 1, wherein the carrying surface and the strip-shaped longitudinal rib are fixed by a common frame and are spatially arranged relative to one another such that a gap-shaped interspace for the introduction of the clip projection remains between the carrying surface and the strip-shaped longitudinal rib, the clip projection is placed against the strip-shaped longitudinal rib through the gap-shaped interspace and the spring strip is plugged onto the strip-shaped longitudinal rib proceeding from the foil-free side of the carrying surface.
Claim 4
Dependent Claim
96 words
A contact device for the electrical connection of a conductive foil lying against a carrying surface to a spring strip, wherein at least one side of a clip projection connected to the conductive foil comprises a plurality of electrical contact surfaces to which individual contact springs of the spring strip are respectively allocated, comprising a strip-shaped longitudial rib, arranged at a fixed position relative to the carrying surface forcing the clip projection out of the plane of the carrying surface, the clip projection engaging against said strip-shaped longitudinal rib upon contact pressure of the contact springs.
Claim 5
Dependent Claim
96 words
A contact device for the electrical connection of a conductive foil lying against a carrying surface to a spring strip, wherein at least one side of a clip projection connected to the conductive foil comprises a plurality of electrical contact surfaces to which individual contact springs of the spring strip are respectively allocated, comprising a strip-shaped longitudial rib, arranged at a fixed position relative to the carrying surface forcing the clip projection out of the plane of the carrying surface, the clip projection engaging against said strip-shaped longitudinal rib upon contact pressure of the contact springs.
Claim 6
Dependent Claim
128 words
A contacting device for the electrical connection of a conductive foil lying against a carrying surface to a spring strip, wherein at least one side of a clip projection connected to the conductive foil comprises a plurality of electrical contact surfaces to which individual contact springs of the spring strip are respectively allocated, comprising a strip-shaped longitudinal rib forcing the clip projection out of the plane of the carrying surface, the clip projection engaging against said strip-shaped longitudinal rib upon contact pressure of the contact springs, said carrying surface in the strip-shaped longitudinal rib are fixed by a common frame and are spatially arranged relative to another such that a gap-shaped interspace for the introduction of clip projection remains between the carrying surface and the strip-shaped longitudinal rib.
Claim 7
Dependent Claim
128 words
A contacting device for the electrical connection of a conductive foil lying against a carrying surface to a spring strip, wherein at least one side of a clip projection connected to the conductive foil comprises a plurality of electrical contact surfaces to which individual contact springs of the spring strip are respectively allocated, comprising a strip-shaped longitudinal rib forcing the clip projection out of the plane of the carrying surface, the clip projection engaging against said strip-shaped longitudinal rib upon contact pressure of the contact springs, said carrying surface in the strip-shaped longitudinal rib are fixed by a common frame and are spatially arranged relative to another such that a gap-shaped interspace for the introduction of clip projection remains between the carrying surface and the strip-shaped longitudinal rib.
Claim 8
Dependent Claim
23 words
A contact device according to claim 3, including a spring strip that can be plugged onto the strip-shaped longitudinal rib with positive lock.
Claim 9
Dependent Claim
25 words
A contacting device according to claim 5, wherein the strip-shaped longitudinal rib is slanted at at least one longitudinal edge mortised against the clip projection.
Claim 10
Dependent Claim
17 words
A contacting device according to claim 6, wherein the spring strip is secured to a flat module.
