Field coil assembly for electromagnetic clutch
View Patent ↗A field coil assembly for an electromagnetic clutch, which includes an electromagnetic coil body formed by winding an electromagnetic coil; a bobbin for supporting the electromagnetic coil body; a field core for receiving the bobbin and the electromagnetic coil body; a holder mounted to the electromagnetic coil body; and a thermal fuse installed to the holder to be connected to the electromagnetic coil body, wherein the holder having the thermal fuse installed thereto is provided with an elastic member for elastically supporting the thermal fuse upwards. Thus, the height of the thermal fuse installed to the holder can be adjusted.
1. A field coil assembly for an electromagnetic clutch, comprising:
an electromagnetic coil body formed by winding an electromagnetic coil;
a bobbin for supporting the electromagnetic coil body;
a field core for receiving the bobbin and the electromagnetic coil body;
a holder mounted to the electromagnetic coil body; and
a thermal fuse fixed to the holder to be electrically connected to the electromagnetic coil body,
wherein the holder having the thermal fuse installed thereto is provided with an elastic member configured so that the height of the thermal fuse can be adjusted, and
wherein the elastic member is an elastic support plate which is partially incised from the holder to elastically support the thermal fuse installed to the holder.
2. The field coil assembly as claimed in claim 1 , further comprising protrusions respectively formed at both sides of the holder to enclose the thermal fuse, wherein the elastic support plate is formed by protruding a portion of the holder in the same direction as the protrusions.
3. A field coil assembly for an electromagnetic clutch, comprising:
an electromagnetic coil body formed by winding an electromagnetic coil;
a bobbin for supporting the electromagnetic coil body;
a field core for receiving the bobbin and the electromagnetic coil body;
a holder mounted to the electromagnetic coil body; and
a thermal fuse fixed to the holder to be electrically connected to the electromagnetic coil body,
wherein the holder having the thermal fuse installed thereto is provided with an elastic member configured so that the height of the thermal fuse can be adjusted, and
wherein the elastic member is a rubber plate installed to the holder.
4. A field coil assembly for an electromagnetic clutch, comprising:
an electromagnetic coil body formed by winding an electromagnetic coil;
a bobbin for supporting the electromagnetic coil body;
a field core for receiving the bobbin and the electromagnetic coil body;
a holder mounted to the electromagnetic coil body; and
a thermal fuse fixed to the holder to be electrically connected to the electromagnetic coil body,
wherein the holder having the thermal fuse installed thereto is provided with an elastic member configured so that the height of the thermal fuse can be adjusted, and
wherein the elastic member is a dot formed to protrude from the holder.
