Terminal base having an elctrical connector to connect a coil-side terminal of an elctric motor to an inverter-side terminal of an inverter

A terminal base that is disposed on an electrical connection path between a coil of an electric motor accommodated inside a case and an inverter disposed outside the case and connects a coil-side terminal serving as a terminal on a coil side to an inverter-side wiring member serving as a wiring member on an inverter side, the terminal base comprising:

• a connector that electrically connects the inverter-side wiring member and the coil-side terminal;
• a fastener that fixes the coil-side terminal to a first terminal serving as one terminal of the connector;
• and
• a terminal base main body that holds the connector, wherein:
• the fastener includes an internal screw and an external screw that is threaded into the internal screw;
• the terminal base main body includes an attachment that is attached to the case, a screw insertion hole in which the external screw inserted from the outside to the inside of the case is disposed, a coil terminal insertion hole which is disposed inside the case and into which the coil-side terminal is inserted, and an internal screw holder that holds the internal screw;
• the coil terminal insertion hole is formed to intersect with the screw insertion hole;
• the first terminal is disposed at an intersection between the coil terminal insertion hole and the screw insertion hole;
• a direction parallel to a rotation axis of the external screw disposed in the screw insertion hole is defined as an axial direction, and a side directed to the inside of the case in the axial direction is defined as an axially inner side;
• the internal screw holder is formed in a portion of the screw insertion hole, on the axially inner side with respect to the intersection;
• and
• when the external screw extends through a through hole formed in the first terminal and a through hole formed in the coil-side terminal and is threaded into the internal screw, the coil-side terminal is fixed to the first terminal.
