Coil winding wire contacting method for miniature relay mfr

摘要

The method involves contacting the winding wire (12) of a coil with a contact pin (10). An end section of the winding wire is wrapped around an end section (11) of the contact pin with several coils. The contact pin is then brought into contact with a liquid-free soft solder (14). The solder is melted by contact free supply of heat under protective gas for solder temperatures. The wound end section of the contact pin is arranged in the region of two electrodes (2,3) which have their tips facing each other. A light arc (5) is ignited between the two electrodes whose strength and duration is matched to the melting of the soft solder.
