Wire arrangement body, busbar module and power-supply unit

Abstract

A wire arrangement body includes: a wire arrangement groove portion of a groove shape that receives one or more wires; a lid portion that is rotatably connected to the wire arrangement groove portion about a first hinge and covers the wire arrangement groove portion so as to seal a groove opening of the wire arrangement groove portion; and a wire drawing piece that is rotatably connected to the lid portion about a second hinge. The wire arrangement body is provided so that a rotation axis of the second hinge crosses at a right angle to a rotation axis of the first hinge.

Description

technical field [0001] The present invention relates to a power supply device used in a hybrid vehicle, an electric vehicle, etc., a busbar module constituting the power supply device, and a wiring body constituting the busbar module. Background technique [0002] For example, the power supply apparatus shown in JP-A-2009-43637 (WO 2009 / 022521A1) is installed in various vehicles such as an electric vehicle running with an electric motor, a hybrid vehicle running with both an engine and a motor, and the like, as a power source for the motor. The power supply device includes: a battery assembly having a plurality of batteries, wherein the positive electrode is provided on one end and the negative electrode is provided on the other end, and the positive electrode and the negative electrode are alternately arranged adjacent to each other; and a busbar module, the busbar module Overlaid on the surface of the battery assembly where the electrodes are provided.

Problems solved by technology

[0012] However, in the busbar module 101 (ie, the board 106), the first hinge 191 and the second hinge 192 are along the X direction ( Figures 9A to 9C in the front-rear direction) are arranged in parallel, so that generally, a plurality of electric wires 105 such as Figure 9A shown in the second receiving portion 164, and when the plurality of electric wires 105 are taken out from the notch portion 195 provided in the cover portion 167 and tightened, along Figure 9A A pulling force F1 that pulls up in the arrow Z direction shown is also applied to the electric wire extracting piece 196, so that a rotational force F2 that rotates the cover portion 167 around the first hinge 191 as the center of rotation is generated by this force F1 (that is, the cover portion 167 is rotated). part 167 turns upward around the first hinge 191 as the center of rotation), so there is a fear that the cover part 167 may be opened

In this way, the cover portion 167 is opened, so that the wire 105 is Figure 9B As shown, it is sandwiched between the second receiving part 164 and the cover part 167 (the snapping of the electric wire), or the electric wire 105 is as Figure 9C shown disengaged from the second receiving portion 164, so this is a problem of not protecting the plurality of wires 105
