Problems solved by technology

Therefore, it takes time and effort to perform the wiring operation of electric wires
[0005] Furthermore, in the bus bar module described above, in plan view, since the accommodating portion of the connection end of the electric wire with each bus bar is provided between the bus bar accommodating portion and the electric wire routing groove portion, and the downstream electric wire is arranged so as not to be connected with the upstream The connecting ends of the electric wires interfere, so the width dimension of the bus bar module increases

Abstract

A busbar module includes a case to be attached to a battery assembly, busbars and electric wires having a connection end to be connected to the busbars. The case includes busbar accommodation portions to accommodate the busbars and an electric wire routing groove portion to accommodate the electric wires. The electric wire routing groove portion includes a connection end accommodation portion to accommodate the connection end, an accommodation portion cover and an electric wire lead-out portion configured such that the electric wires are drawn out from the connection end accommodation portion toward a direction. An outer surface of the accommodation portion cover is to form a bottom surface of a routing path configured such that the electric wires drawn out from the connection end accommodation portion extend in the routing path.

Description

technical field [0001] The invention relates to a bus bar module. Background technique [0002] A power supply device mounted on various vehicles such as an electric car that runs with an electric motor and a hybrid car that runs with a combination of an engine and a motor includes a bus bar module that has multiple cells to be connected to electrodes of multiple cells. a bus bar. [0003] The bus bar module of the related art includes a plurality of electric wires for voltage detection, the electric wires are electrically connected to the bus bar to detect the voltage of the cell, and these electric wires are housed and routed in a wire routing groove portion, which The portion is provided along the arrangement direction of a plurality of bus bar accommodating portions accommodating the bus bars (for example, see Patent Document JP2018-97987A). In the conventional bus bar module (conductive module), between the bus bar housing part (accommodating space part) and the wire ...
