| (54) | BOBBIN THAT FACILITATES AUTOMATIC WINDING, COIL AND LATCHING RELAY |
| (57) A bobbin that facilitates automatic winding includes a first flange part (1), a second
flange part (2), a third flange part (3), a first winding part (4) and a second winding
part (5), the first winding part (4) is provided between the first flange part (1)
and the second flange part (2), the second winding part (5) is provided between the
second flange part (2) and the third flange part (3); the first flange part (1) is
provided with a plurality of terminal holes, the plurality of terminal holes includes
a first terminal hole (11) for inserting a start terminal (8) and a second terminal
hole (13) for inserting an end terminal (9); the first flange part (1) is provided
with a wire hanging portion, and a bottom end of the wire hanging portion is lower
than a top end of the first flange part (1), and the second flange part (2) is provided
with a first wire guide portion for guiding a enameled wire (7) from the second winding
part (5) to the wire hanging portion. In the present disclosure, a manual winding
of enameled wire is avoided, and the wire hanging portion is used to hang the wire
to reduce the height of the end wire part of the enameled wire (7) located between
the first flange part (1) and the second flange part (2), at the same time, an effective
isolation between the enameled wire layers of the second winding part (5) and the
first winding part (4) can be ensured, and the risk of interlayer breakdown can be
avoided, thereby avoiding the use of a wire crimping mechanism to crimp the wire and
ensuring safety at the same time.
