Abstract

Abstract A contact element and contact element assembly of electrically conducting material, intended, in particular, for surface mounting at a connecting area near the edge of a circuit substrate comprising an opening or recess. The contact element has a flat base face which in the mounted state of the contact element is situated completely or partially opposite the connecting area. The contact element also has at least one positioning device which projects from the flat base face and extends into the opening or recess of the substrate the contact element is mounted to the positioning device may be a positioning finger which fits freely into the opening or recess, or a positioning finger which acts on the substrate in a manner such that a retaining force is provided for keeping the contact element in position.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 122 words
A contact element of electrically conducting material for mounting in electrical contact to electrical contact areas disposed on a surface of a substrate comprising a substantially flat base providing a contact face for connecting to the electrical contact areas of the substrate, said flat base including a pair of strips extending along said contact face. a positioning finger formed integrally with and projecting from said flat base between said strips and adapted to be received in a recess formed in the surface of the substrate adjacent each said contact area to maintain the face of the flat base in position on said contact area, and contact means extending in a direction opposite to said flat base to mate with other connector means.
Claim 2
Dependent Claim 122 words
A contact element of electrically conducting material for mounting in electrical contact to electrical contact areas disposed on a surface of a substrate comprising a substantially flat base providing a contact face for connecting to the electrical contact areas of the substrate, said flat base including a pair of strips extending along said contact face. a positioning finger formed integrally with and projecting from said flat base between said strips and adapted to be received in a recess formed in the surface of the substrate adjacent each said contact area to maintain the face of the flat base in position on said contact area, and contact means extending in a direction opposite to said flat base to mate with other connector means.
Claim 3
Dependent Claim 17 words
A contact element according to one of claim 1 wherein the positioning finger is a straight pin.
Claim 4
Dependent Claim 20 words
A contact element according to one of the claim 1 wherein the positioning finger is curved in a serpentine shape.
Claim 5
Dependent Claim 18 words
A contact element according to one of the claim 1 wherein the positioning finger has a bent-back shape.
Claim 6
Dependent Claim 46 words
A circuit board substrate comprising a plurality of electrical contact areas formed along an edge of one main surface of the substrate, and a recess formed adjacent each said contact area, said substrate having surface mounted thereto a plurality of contact element according to claim 1.
Claim 7
Dependent Claim 37 words
A contact element according to claim 1 wherein the positioning finger when received in the recess acts on the substrate in a manner such that a retaining force is provided for keeping the contact element in position.
Claim 8
Dependent Claim 27 words
A contact element according to claim 6 wherein the positioning finger is provided with laterally projecting teeth which exert a force on the substrate within the recess.
Claim 9
Dependent Claim 34 words
A contact element according to claim 6 wherein the positioning finger is provided at its free end with a stop means to engage a face of the substrate when the contact element is mounted.
Claim 10
Dependent Claim 20 words
A contact element according to claim 8 wherein the stop means is a lip disposed transversely on the positioning finger.
Claim 11
Dependent Claim 19 words
A contact element according to claim 8 wherein the stop means is a proturberance formed from the positioning finger.
Claim 12
Dependent Claim 53 words
A contact element according to claim 8 wherein the contact areas are disposed along an edge of the substrate surface and wherein the flat base is provided at its contact face with at least one other stop means which is disposed adjacent the edge of the substrate when the contact element is mounted.
Claim 13
Dependent Claim 39 words
A contact element according to claim 11 wherein said other stop means is a projection extending from said flat base in the same direction as the positioning member and providing a stop face against the edge of the substrate.
Claim 14
Dependent Claim 31 words
A contact element according to claim 11 wherein the other stop means is at least one lip extending from the flat base face in the same direction as the positioning member.
Claim 15
Dependent Claim 39 words
