Abstract
Abstract In a connector for printed circuit board a traction yoke is a frame in which two parallel contact plates are positioned. The contact plates are mechanically and electrically combined in a single contact piece which can be rotated about a clamping bolt received in the contact piece and clamping the connector to the printed circuit board.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
190 words
A connector for coated printed circuit boards, comprising a traction yoke; two contact plates positioned in said yoke; a connection plate-like portion connected with an upper one of said contact plates and located thereabove; and a clamping bolt; said contact plates with said connection portion being mechanically and electrically connected to each other so as to form a single unitary contact piece, said contact plates being arranged so that a printed circuit board is engageable at its edge between said plates and a lead can be inserted between a lower one of said contact plates and a bottom wall of said traction yoke, and said clamping bolt being rotatable so that during its rotation it is rotatably held in said connection portion of said contact piece, is supported on an upper contact plate of said contact piece, and draws said traction yoke towards said lower contact plate of said contact piece whereby said lead is clamped between said bottom wall of said yoke and said lower contact plate of said contact piece while said printed circuit board is clamped between said upper and lower contact plates of said contact piece.
Claim 2
Dependent Claim
190 words
A connector for coated printed circuit boards, comprising a traction yoke; two contact plates positioned in said yoke; a connection plate-like portion connected with an upper one of said contact plates and located thereabove; and a clamping bolt; said contact plates with said connection portion being mechanically and electrically connected to each other so as to form a single unitary contact piece, said contact plates being arranged so that a printed circuit board is engageable at its edge between said plates and a lead can be inserted between a lower one of said contact plates and a bottom wall of said traction yoke, and said clamping bolt being rotatable so that during its rotation it is rotatably held in said connection portion of said contact piece, is supported on an upper contact plate of said contact piece, and draws said traction yoke towards said lower contact plate of said contact piece whereby said lead is clamped between said bottom wall of said yoke and said lower contact plate of said contact piece while said printed circuit board is clamped between said upper and lower contact plates of said contact piece.
Claim 3
Dependent Claim
34 words
The connector as defined in claim 1, wherein a printed circuit board is non-slotted at said edge, said yoke having at a side thereof facing said edge a recess which receives said contact piece.
Claim 4
Dependent Claim
19 words
The connector as defined in claim 1, wherein said contact plates are connected to each other by a cross-piece.
Claim 5
Dependent Claim
19 words
The connector as defined in claim 2, wherein said contact plates are connected to each other by a cross-piece.
Claim 6
Dependent Claim
19 words
The connector as defined in claim 3, wherein said contact piece is made of a stamped-out and bent piece.
Claim 7
Dependent Claim
46 words
The connector as defined in claim 1, wherein said clamping bolt has a circular recess, at which the clamping bolt is connected to said connection portion of the contact piece, said bolt being rotatable relative to said connection portion of said contact piece at said recess.
Claim 8
Dependent Claim
21 words
The connector as defined in claim 1, wherein said connection portion is formed with a locking recess receiving said clamping bolt.
Claim 9
Dependent Claim
30 words
The connector as defined in claim 7, wherein said contact piece is a stamped element, said connection portion being bent over from a free outer edge of said upper plate.
Claim 10
Dependent Claim
38 words
The connector as defined in claim 8, wherein said locking recess is elongated and its elongation is directed at an angle of 90° relative to a direction of insertion of the contact plates on the printed circuit board.
Claim 11
Dependent Claim
22 words
The connector as defined in claim 3, further including an additional connecting means provided in said yoke for connecting a conductor thereto.
Claim 12
Dependent Claim
52 words
The connector as defined in claim 3, wherein said contact plates are parallel to each other and spaced from each other by a distance, said distance and the material of said contact piece being selected so that the contact piece is resiliently clamped on said printed circuit board at a predetermined position.
Claim 13
Dependent Claim
41 words
The connector as defined in claim 11, wherein said contact plates have sides facing said printed circuit board in an inserted position, said sides being formed with locking cams, said board having arresting recesses receiving said cams in said inserted position.
Claim 14
Dependent Claim
37 words
The connector as defined in claim 11, wherein said contact plates have sides facing said printed circuit board in an inserted position, said sides having locking teeth which produce grooves in said board in said inserted position.
