Problems solved by technology

[0005] On the other hand, in the structure described in Patent Document 1, the terminal pin is held by the slit hole, but since the holding position is provided on the partition wall separated from the connector insertion part, it is impossible to hold the connection between the terminal pins. The connection part where the device insertion part extends, making it difficult to prevent the connection part from tilting

Abstract

A motor is capable of effectively suppressing displacement of a connecting part of a terminal pin extending at a connector inserting part. In the motor, a connector shell (92) of an outer cover (9) is provided with a projection (95), the projection (95) supports a base side of a second part (82) from two sides of a direction (X-axis direction) perpendicular to two directions, i.e., an extension direction (Y-axis direction) of a first part (81) of a terminal pin (8) and an extension direction (Z-axis direction) of the second part (82) (connecting part), the second part (82) extends towards one side (Z1) of the Z-axis direction at a connector inserting part (90). Therefore, the base side of the second part (82) can be supported from two sides of the X-axis direction through the projection (95). In this way, the case that the connector cannot be inserted into the connector inserting part as the second part (92) of the terminal pin (8) inclines towards the X-axis direction when the connector is inserted into the connector inserting part can be avoided.

Description

technical field [0001] The present invention relates to a motor including a cover that covers a connection portion of a terminal pin from a radially outer side to form a connector insertion portion. Background technique [0002] In a motor in which the connector insertion portion is formed by a cover that covers the connection portion of the terminal pins connected to the connector from the radially outer side, the plurality of terminal pins held by the terminal block provided on the radially outer side of the motor main body are After extending radially outward, it bends toward the motor axis direction as a connection portion and is positioned inside the connector insertion portion. Here, if there is a partition between the terminal block and the housing, the terminal pins cannot be extended to the connector insertion portion. Therefore, there has been proposed a motor in which a slit hole extending in the motor axis direction is provided on the partition wall. In such a m...
