Abstract
Abstract A process and device are provided for welding a flat multiwire cable onto a printed circuit, the wires of the cable being evenly spaced and the printed circuit comprising conductive strips of equal spacing. In accordance with the invention, the conductors are stripped close to their end, bent so that their lower portion is of the same length as the conductive strip and undergo a preliminary cut. The lower portion of the wire is there inserted onto the conductive strip and heated. The portion which is preliminary cut, is removed by plying.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
A welding device for use in welding plural wires of a multiwire flat cable of the type wherein the wires are arranged in predetermined evenly spaced insulated relation within an insulating sheath, to a printed circuit having conductive zones of a predetermined spacing corresponding to the spacing of the wires, said device comprising a welding head and a pedestal below said welding head, aid pedestal having first means for supporting a printed circuit including a slideway for slideably receiving a printed circuit, and second means on said pedestal defining a guide path for a multiwire flat cable, said second means including a pair of guide feed spaced transversely of said guide path and a cable holding spring extending longitudinally of said guide path and in elevated relation to said pedestal for holding a cable in an elevated position relative to said pedestal.
Claim 2
Dependent Claim
142 words
A welding device for use in welding plural wires of a multiwire flat cable of the type wherein the wires are arranged in predetermined evenly spaced insulated relation within an insulating sheath, to a printed circuit having conductive zones of a predetermined spacing corresponding to the spacing of the wires, said device comprising a welding head and a pedestal below said welding head, aid pedestal having first means for supporting a printed circuit including a slideway for slideably receiving a printed circuit, and second means on said pedestal defining a guide path for a multiwire flat cable, said second means including a pair of guide feed spaced transversely of said guide path and a cable holding spring extending longitudinally of said guide path and in elevated relation to said pedestal for holding a cable in an elevated position relative to said pedestal.
Claim 3
Dependent Claim
43 words
A welding device in accordance with claim 1 wherein said slideway extends transversely of said guide path, and there are stop means at one end of said slideway for transversely positioning a printed circuit in alignment with wires positioned in said guide path.
Claim 4
Dependent Claim
37 words
A welding device in accordance with claim 2 wherein said stop means includes a bolt, and mounting means mounting said bolt for lateral displacement, said mounting means including a micrometer screw supporting said bolt for movement therewith.
Claim 5
Dependent Claim
20 words
A welding device according to claim 1 wherein said first means includes two embossings at the center of said slideway.
Claim 6
Dependent Claim
69 words
A welding device according to claim 1 wherein said welding head includes a peen having a lower end in the form of a plurality of teeth extending transversely of said guide path and having spaces therebetween for receiving wires, said spaces having a spacing corresponding to the spacing of wires of an intended cable and said teeth being of a width in accordance with the space between adjacent wires.
Claim 7
Dependent Claim
43 words
A welding device in accordance with claim 5 wherein said slideway extends transversely of said guide path, and there are stop means at one end of said slideway for transversely positioning a printed circuit in alignment with wires positioned in said guide path.
Claim 8
Dependent Claim
37 words
A welding device in accordance with claim 6 wherein said stop means includes a bolt, and mounting means mounting said bolt for lateral displacement, said mounting means including a micrometer screw supporting said bolt for movement therewith.
Claim 9
Dependent Claim
46 words
A welding device according to claim 7 together with a binocular microscope for viewing said teeth of said welding peen and a printed circuit carried by said first means and for facilitating alignment of a printed circuit with said peen by means of said micrometer screw.
