Securing and contacting terminal pins in support plate - uses heating of pins inserted orthogonally in plate bores by current pulses, with simultaneous pin deformation

摘要

The terminal pins to be secured and contacted are fitted with a strip for incorporation in a support plate of a circuit wiring. The pins (2) are set orthogonally through bores in the support plate, heated by a current pulse and mechanically deformed in such manner than an electric contact is formed with the circuit wiring. If a soft solder layer is provided on the wiring, or the pin, the current pulse provides the actual soldering. The device used for the process contains a clamping electrode (6), retaining the terminal pin up to its strip (5). The electrode pushes the pin through the plate bore, while a sprung counter electrode (9) deforms the pin end protruding from the plate.
