Abstract
Abstract Contact strip terminal for electrically interconnecting at least one flat conductor of a flexible conductor film with at least a conductor lead wire, said contact strip terminal comprising a strip-type base part (2) of electrically conducting material and at least two groups of teeth (5) projecting outwards relative to a surface of said base part (2) for contacting at least one flexible conductor of said flexible conductor film, wherein each tooth (5) has a sharp pointed end (9) and projects over its total length mainly at a right angle away from said surface of said base part (2), the contact strip terminal further comprising an edge clip connector for connecting the terminal with contact faces of one or both surfaces near an edge of a substrate, the edge clip connector comprising a stem strip (34) and a clip contact (35) in the form of a closed flat longitudinal loop strip which at one end passes into the stem strip (34) and which is bent at the other end backwards about a transverse axis (38) of said flat loop, so that the legs (36, 37) formed by the two halves of said loop come to rest adjacent to each other and together define an approximately U-shaped clip opening. <IMAGE>

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A contact strip terminal for electrically interconnecting a flat, flexible conductor film and a conductor lead wire, said contact strip terminal comprising: a flat, strip-like base formed of electrically conductive material, said base having first and second surfaces and first and second longitudinal edges, a first group of teeth formed integrally with and projecting from the first surface of the base, said first group of teeth being adapted to pierce into the flexible conductor film and electrically contact one of the conductors in said film, a second group of teeth formed integrally with and projecting from the second surface of the base in a direction opposite to the first group of teeth, and at least one lip-like member projecting from the first longitudinal edge of the base in the same direction as said second group of teeth, said lip-like member being deformable in the direction of the base for clamping said conductor lead wire between said lip-like member and said base.
Claim 2
Dependent Claim
161 words
A contact strip terminal for electrically interconnecting a flat, flexible conductor film and a conductor lead wire, said contact strip terminal comprising: a flat, strip-like base formed of electrically conductive material, said base having first and second surfaces and first and second longitudinal edges, a first group of teeth formed integrally with and projecting from the first surface of the base, said first group of teeth being adapted to pierce into the flexible conductor film and electrically contact one of the conductors in said film, a second group of teeth formed integrally with and projecting from the second surface of the base in a direction opposite to the first group of teeth, and at least one lip-like member projecting from the first longitudinal edge of the base in the same direction as said second group of teeth, said lip-like member being deformable in the direction of the base for clamping said conductor lead wire between said lip-like member and said base.
Claim 3
Dependent Claim
48 words
A contact strip terminal according to claim 1, further comprising a third group of teeth projecting from said first surface of the base in the same direction as said first group of teeth, said second group of teeth being disposed between said first and third groups of teeth.
Claim 4
Dependent Claim
109 words
An edge clip connector for interconnecting the contact strip terminal of claim 1 with contact faces near the edge of a substrate, said connect or comprising an assembly obtained in one stamping operation from a flat sheet of resilient metal and comprising said contact strip terminal, a stem strip and a clip contact in the form of a closed flat loop strip which at one end passes into the stem strip and which is bent about the symmetrical transverse axis, so that the legs of the two halves of the loop come to rest adjacent to each other and together define an approximately U-shaped clip opening on either side.
Claim 5
Dependent Claim
89 words
A process for the production of one or more edge clip connectors according to claim 3 in which the edge clip connectors are stamped out of a flat sheet of resilient metal and by means of a stem strip are held firmly on a carrier strip made from the sheet, while after the stamping operation the closed flat loop strip thus obtained is bent about the symmetrical transverse axis, and the stem strip with its clip contact is bent over at right angles relative to the contact strip terminal.
Claim 6
Dependent Claim
132 words
An edge clip connector according to claim 3 wherein one leg of each half of the loop is a meander shape with at least two inward-directed supporting bracket contact points, and the other leg is a slight V-shape, whose top is directed inwards and opposite the bend lying between the two supporting bracket contact points of the one leg, so that the substrate in question can be inserted parallel to the outward-projecting leg part of the other leg at an angle to the longitudinal direction of the clip contact until its edge lies in the said bend of the one leg and subsequently can be introduced with lever action on the V-shape of the other leg along the longitudinal direction up to the closed end of the two halves of the loop.
Claim 7
Dependent Claim
34 words
An edge clip connector according to claim 5 wherein the contact strip terminal is perpendicularly bent with respect to the longitudinal axis of the edge clip connector for interconnection with a separate flexible conductor.
Claim 8
Dependent Claim
67 words
A contact strip terminal according to claim 1, further comprising second and third lip-like members projecting from the second longitudinal edge of the base in the same direction as and opposite to said first lip-like member, said second and third lip-like members also being deformable in the direction of the base to interdigitate with said first lip-like member in clamping said conductor lead wire to said base.
Claim 9
Dependent Claim
50 words
A contact strip terminal according to claim 7, wherein said lip-like members are disposed adjacent to said second group of teeth so that when said members are deformed to clamp the conductor lead wire to the base the teeth of said second group will electrically contact the conductor lead wire.
Claim 10
Dependent Claim
36 words
A contact strip terminal according to claim 7, wherein at least one of said lip-like members has several sharp pointed projections which electrically contact the conductor lead wire when it is clamped by said lip-like members.
Claim 11
Dependent Claim
28 words
A contact strip terminal according to claim 1, wherein the teeth of each said group are provided with sharp edges and are arranged in a closed peripheral line.
Claim 12
Dependent Claim
24 words
A contact strip terminal according to claim 10, wherein each said group of teeth comprises four pointed, triangular shaped teeth arranged in a circle.
