Abstract

An insulating housing for a motor terminal includes a plurality of electricity supply members each having a connector terminal for connection to a power supply and a coil terminal to which a motor coil is connected; and an insulating housing main body for insulating the plurality of electricity supply members from each other and holding the electricity supply members. The insulating housing main body integral with the electricity supply members is formed by insert-molding with the plurality of electricity supply members spaced in an insulating interval from each other and disposed on the same plane after bending, then the connector terminal is protruded within a connector insertion opening formed integral with the insulating housing main body, and the coil terminal is protruded onto the same plane as the peripheral surface of the insulating housing main body.

Claims

1. An insulating housing for a motor terminal comprising:

a plurality of electricity supply members each having a connector terminal for connection to a power supply and a coil terminal to which a motor coil is connected; and

an insulating housing main body for insulating the plurality of electricity supply members from each other and holding the electricity supply members; and

a signal supply member having a signal terminal for connection to a signal detection terminal and a sensor terminal to which a sensor is connected,

wherein insert-molding is performed, with the plurality of electricity supply members disposed spaced in an insulating interval from each other on the same plane and the signal supply member disposed at a position where the signal supply member does not act on the electricity supply members, to thereby form the insulating housing main body integral with the plurality of electricity supply members and the signal supply member,

the signal terminal is bent to be protruded within a signal connector insertion opening formed integral with the insulating housing main body,

the sensor terminal is protruded in an assembling direction of the insulating housing main body to a motor,

2. The insulating housing for a motor terminal according to claim 1, wherein a coil of each of the respective phases of a motor is wound in series with the winding direction reversed with respect to the adjoining magnetic poles, the winding beginning end of each of the coils of the respective phases and the winding ending end of the adjoining coil are connected with each other in succession, and the connected ends are further connected to the respective coil terminals to connect the coils in a delta-connection.

3. An insulating housing for a motor terminal comprising:

a plurality of electricity supply members each having a connector terminal for connection to a power supply and a coil terminal to which a motor coil is connected;

a common terminal member having a plurality of common terminals to which the motor coils are connected; and

an insulating housing main body for insulating the plurality of electricity supply members and the common terminal member from each other to be held,

wherein the insulating housing further includes a signal supply member having a signal terminal for connection to a signal detection terminal and a sensor terminal to which a sensor is connected,
