Embodiment Construction

[0015] One embodiment of the electric supercharger includes: an electric motor that rotates the rotor; a motor housing that accommodates the electric motor inside; a control unit that is disposed outside the motor housing and controls driving of the electric motor; and an energization mechanism that The current from the control unit is supplied to the electric motor through a through-hole connecting the inside and outside of the motor case, and the energization mechanism includes a rod that is sealed while being inserted into the through-hole, and a connector connected to at least one end of the rod. , and the bus bar connected with the connector, the relative positional deviation of the connector absorbing rod relative to the connector.

[0016] In such an electric supercharger, the sealed rod is connected relative to the connector connected to the busbar. In the event that the position of the lever is relatively offset with respect to the busbar, the position of the lever wi...

Abstract

The electric supercharger of the present invention includes: an electric motor for rotationally driving the rotor; a motor casing for accommodating the electric motor inside; a control unit arranged outside the motor casing for controlling the driving of the electric motor; The through-hole communicated with the electric motor is supplied with the electric current from the control part to the electric motor. The connector is connected to the bus bar, and the relative position of the connector absorbing rod relative to the connector is offset.

Description

technical field [0001] The present invention relates to electric superchargers. Background technique [0002] Patent Document 1 discloses an electric compressor in which a compressor and an electric motor are integrated. The electric compressor includes a case including a middle case for accommodating the compressor, a rear case for accommodating an electric motor, and a front case for accommodating a drive circuit. Furthermore, the drive circuit and the electric motor are electrically connected via signal lines via sealed terminals fixed to the case. [0003] Patent Document 1: International Publication No. 2008 / 102697 [0004] Usually, in a sealed terminal, the periphery of the conductive rod is sealed with an insulator such as glass. In this case, if the signal line connected to the rod is a thin and flexible wire, even if the relative position of the rod and the signal line is shifted, excessive force will not be applied from the signal line to the rod. However, sinc...
