Abstract

Provided is a battery wiring module that allows module-side terminals to be easily mounted to a housing. The battery wiring module includes module-side terminals that are electrically connected to bus bars connecting battery terminals of a plurality of battery cells; wires with ends on one side connected to the module-side terminals; and a housing for accommodating the wires and the module-side terminals. The housing includes a plurality of terminal accommodating portions for accommodating the module-side terminals. The terminal accommodating portions include insertion ports into which the module-side terminals are partially inserted, and recesses that are located upstream of the insertion ports in a direction in which the module-side terminals are inserted and that are lower than terminal seat surfaces on which the module-side terminals can be placed.

First claim

What is claimed is:

1 . A battery wiring module comprising:
module-side terminals that are electrically connected to bus bars connecting battery terminals of a plurality of battery cells; wires with ends on one side connected to the module-side terminals; and a housing for accommodating the wires and the module-side terminals, wherein the housing includes a plurality of terminal accommodating portions for accommodating the module-side terminals, and the terminal accommodating portions include insertion ports into which the module-side terminals are partially inserted, and recesses that are located upstream of the insertion ports in a direction in which the module-side terminals are inserted and that are lower than terminal seat surfaces on which the module-side terminals can be placed.

2 . The battery wiring module according to claim 1 , further comprising
inclined surfaces that are inclined from the terminal seat surfaces to the insertion ports.

3 . The battery wiring module according to claim 1 ,
wherein the insertion ports are each formed from a side wall to a bottom surface of the terminal accommodating portion.

4 . The battery wiring module according to claim 1 ,
wherein the recesses each have a plate thickness greater than or equal to the smallest plate thickness of the terminal seat surface.

5 . The battery wiring module according to claim 1 ,
wherein the module-side terminals each include a first terminal and a second terminal, the first terminal includes a first terminal body portion that is connected to the bus bar, and a first inserted portion that extends from the first terminal body portion and that is inserted into the insertion port, the second terminal includes a second terminal body portion that is connected to the bus bar, and a second inserted portion that extends from the second terminal body portion and that is inserted into the insertion port, the first inserted portion is formed extending from a position eccentric toward a center of an end portion of the first terminal body portion, and the second inserted portion is formed extending from a position eccentric toward a side edge of an end portion of the second terminal body portion, and has a width different from that of the first inserted portion.

6 . The battery wiring module according to claim 5 ,
wherein the terminal accommodating portions each include a first terminal accommodating portion corresponding to the first terminal, and a second terminal accommodating portion corresponding to the second terminal, the first terminal accommodating portion includes a first insertion port into which the first inserted portion is inserted, the second terminal accommodating portion includes a second insertion port into which the second inserted portion is inserted, and one of the first insertion port and the second insertion port has an opening having a width larger than that of one of the first inserted portion and the second inserted portion that corresponds thereto, and has an opening having a width smaller than that of the other one of the first inserted portion and the second inserted portion that does not correspond thereto.
