Abstract

A motor wiring structure of the present invention relates to motor wiring for supplying electric power to coils which are respectively wound around split cores provided in a stator. The motor wiring structure includes a power supply-side terminal disposed on a power supply side, multiple coil connection-side terminals configured to be connected respectively to winding wire terminals of the coils, and multiple conductor wires each independently connecting the power supply-side terminal and one of the multiple coil connection-side terminals to each other. Moreover, the motor wiring structure includes a positioning and heat-dissipating protrusion which is provided to the coil connection-side terminal, and which is configured to position the coil connection-side terminal with respect to the stator and dissipate heat during thermal crimping with the coil.

Dependent claims

A motor wiring structure for supplying electric power to coils which are respectively wound around split cores provided in a stator, the structure comprising:

a power supply-side terminal disposed on a power supply side;
a plurality of coil connection-side terminals respectively thermocompression bonded to winding wire terminals of the coils;
and
a plurality of conductor wires each independently connecting the power supply-side terminal and one of the plurality of the coil connection-side terminals to each other, each of the plurality of conductor wires including one end connected to the power supply-side terminal and the other end singly connected to one of the coil connection-side terminals,
wherein each of the plurality of coil connection-side terminals includes:
a thermocompression bonding portion thermocompression bonded to the winding wire terminal of the coil,
a crimping portion crimped to the conductor wire,
a joint portion joining the thermocompression bonding portion and the crimping portion to each other, and
a positioning and heat-dissipating protrusion formed on a part of the joint portion, between the thermocompression bonding portion and the crimping portion,
wherein the positioning and heat-dissipating protrusion is positioned and fixed at a predetermined position with respect to the stator,
wherein the positioning and heat-dissipating protrusion is configured to dissipate heat during thermocompression bonding the thermocompression bonding portion to the winding wire terminal of the coil by radiation.
