Arrangement for making contact between the conductor tracks of printed circuit boards with contact pins

Claim 1

An arrangement for making contact between electrical conductor tracks of printed circuit boards and contact pins by heating bodies formed of solder material and arranged at the region of predetermined contact locations where contact is to be made, comprising: a displaceable induction loop through which there can flow a high-frequency alternating current in order to generate an electromagnetic alternating field; said induction loop possessing an essentially rectangular-shaped configuration and serving to make contact between the conductor tracks of the printed circuit board and contact pins arranged in rows and spaced very closely in relation to one another and inserted into bores of the printed circuit board, said induction loop being adapted to fit between said rows of pins; said induction loop having two lengthwise extending portions, a loop end, and a substantially U-shaped web provided at the region of said loop end, said substantially U-shaped web constituting a raised connection in relation to a plane containing both of said lengthwise extending portions of the induction loop; a displaceable support member for supporting the induction loop and displaceable with respect to a plane containing the printed circuit board; and said lengthwise extending portions of said substantially rectangular-shaped induction loop comprising two substantially mutually parallel extending leg members arranged relative to said displaceable support member such that upon lowering said support member in the direction of said printed circuit board into coacting relationship with one another there is operatively engaged at least one row of the contact pins at which contact is to be made and such contact pins are simultaneously brought together with related contact locations thereof into the effective region of the electromagnetic alternating field of the induction loop and are thereby substantially uniformly heated.
