Abstract
Abstract A clamp for support and electrical connection of two adjacently positioned printed circuit cards consists of a sheet of electric conducting material and a first and a second piece of insulating material. The sheet has a middle uniform portion and two tapered legs at its ends. The two pieces are formed by extrusion on each side of the middle portion of the sheet and the length of one piece along the middle portion is preferably equal to the distance between the cards. When connecting the cards, the legs are bent perpendicular to the middle portion and their ends are joined to the cards by soldering.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
An interconnecting and supporting clamp for two adjacently situated printed circuit cards, comprising: a rectangular plate of electrical conducting material having a middle portion; a first leg extending from one end of said rectangular plate at a substantially right angle thereto; a second leg extending from the other end of said rectangular plate at a substantially right angle thereto, said legs and said rectangular plate being of the same material and moulded from the same blank such that the transition from said plate to each of said legs is characterized by a smooth curve; a first connection piece of insulating material rigidly fastened on one side face of said middle portion; and a second connection piece of insulating material rigidly fastened on the other side face of said middle portion, the length of said second connection piece as taken in a direction from said first leg toward said second leg being greater than the length of said first connection piece such that said second connection piece extends beyond said first connection piece at both ends of said first connection piece whereby two adjacently situated printed circuit cards may be supported thereby.
Claim 2
Dependent Claim
191 words
An interconnecting and supporting clamp for two adjacently situated printed circuit cards, comprising: a rectangular plate of electrical conducting material having a middle portion; a first leg extending from one end of said rectangular plate at a substantially right angle thereto; a second leg extending from the other end of said rectangular plate at a substantially right angle thereto, said legs and said rectangular plate being of the same material and moulded from the same blank such that the transition from said plate to each of said legs is characterized by a smooth curve; a first connection piece of insulating material rigidly fastened on one side face of said middle portion; and a second connection piece of insulating material rigidly fastened on the other side face of said middle portion, the length of said second connection piece as taken in a direction from said first leg toward said second leg being greater than the length of said first connection piece such that said second connection piece extends beyond said first connection piece at both ends of said first connection piece whereby two adjacently situated printed circuit cards may be supported thereby.
Claim 3
Dependent Claim
60 words
The interconnecting and supporting clamp according to claim 1, wherein said first connection piece is mounted upon the top side face of said rectangular plate, which top side face faces in the direction in which said first and said second legs extend from said plate, said second connection piece being mounted on the bottom side face of said rectangular plate.
Claim 4
Dependent Claim
30 words
The interconnecting and supporting clamp according to claim 2, wherein the width of said rectangular plate is less than the width of either of said first and second connection pieces.
Claim 5
Dependent Claim
37 words
The interconnecting and supporting clamp according to claim 3, wherein each of said first and said second legs is tapered along its length in a direction from said rectangular plate toward the free ends of said legs.
Claim 6
Dependent Claim
91 words
The interconnecting and supporting clamp according to claim 4, further comprising a plurality of said clamps connected together in a side-by-side manner, the connection being a thin piece of said electrical conducting material joining the side edges of said first and second connection pieces such that a first groove is formed between adjacent side edges of respective first connection pieces and a second groove is formed between adjacent side edges of respective second connection pieces, whereby a clamp may be separated from the other clamps via said first and second grooves.
