RELAY COIL ASSEMBLY

Disclosed is a relay coil assembly, comprising a coil frame, an enameled wire, a coil pin, and a signal wire. The coil pin comprises an insertion portion, an enameled wire fixing portion, and a signal wire fixing portion. The signal wire fixing portion is provided with a first engagement recess having an opening facing downward, and the signal wire is engaged in the first engagement recess. A hook element is provided near the edge of the opening and at one of two recess sidewalls of the first engagement recess. A slope section along which the opening gradually enlarges from inside to outside is provided at a location corresponding to the signal wire at one of the two recess sidewalls of the first engagement recess. The invention avoids deficiencies of the prior art when fixing a signal wire to a coil pin of a relay coil assembly by means of welding, and enables a secure and reliable connection between the signal wire and the coil pin in the relay coil assembly.
