Problems solved by technology

The configuration in which the installation space of the electrical structure disclosed in Patent Document 2 is limited cannot fully cope with the above-mentioned various requirements.
[0009] Therefore, it is conceivable to provide a connector on the cover portion on the opposite side of the motor as in the structure disclosed in Patent Document 1, but the structure shown in Patent Document 1 is a structure in which a flexibly movable wiring harness is passed through the wiring hole, It is necessary to pull out the wiring harness from the wiring hole, and it takes time to connect the wiring harness to the connector.

Abstract

An electric pump, including: a motor unit including an end cap attached to a motor cover, and a power supply bus bar integral with the end cap; a pump unit including a rotor having a vane groove for receiving a vane and connecting to the rotation shaft and a pump plate; and a cover covering the pump unit from a side opposite to the motor unit and provided with a connector box surrounding an insertion recessed portion into which the power supply bus bar is inserted. In the electric pump, the pump plate has a penetration hole through which the power supply bus bar can be inserted, wiring is inserted into the power supply bus bar inserted through the penetration hole, the wiring protrudes from a front end side of the penetration hole, and the wiring is electrically connected to a connection unit provided in the insertion recessed portion.

Description

technical field [0001] The present invention relates to an electric pump used to create a negative pressure in a negative pressure chamber of, for example, a brake booster of a vehicle. Background technique [0002] Conventionally, vane vacuum pumps have been used in vehicles such as automobiles to create a negative pressure in a negative pressure chamber of a brake booster. Among such vane vacuum pumps, there is a type of electric pump that uses the power of an electric motor. [0003] In the electric pump described above, a conductive portion for supplying electric power to the rotor of the motor is provided, and there are technical contents disclosed in, for example, Patent Document 1 and Patent Document 2 regarding the conductive portion. Patent Document 1 discloses that a wiring hole is provided in the housing of the pump unit, a wiring harness is passed through the wiring hole, and then connected to a connector at a portion opposite to the motor. In addition, Patent ...
