Structure for attaching service plug

摘要

A structure for attaching a service plug includes an insulating substrate that has openings facing electrodes of a pair of adjacent batteries among a plurality of batteries in a battery module, a pair of connection terminals that are respectively connected to electrodes of the pair of adjacent batteries through the insulating substrate by bolting with nuts, a pair of electric wires whose one ends are connected to the connection terminals respectively, and a connector that is connected to the other ends of the pair of electric wires, and detachably connected with the service plug. The insulating substrate has protrusions which are abutted against the connection terminals respectively, and regulate movement of the connection terminals which simultaneously rotate with rotation of the nuts respectively when being bolted with the nuts.

1. A structure for attaching a service plug which closes or opens a connection between a pair of adjacent batteries among a plurality of batteries in a battery module in which the batteries are arranged so that positive electrodes and negative electrodes of the batteries are alternately arranged, and the positive electrodes and the negative electrodes of the adjacent batteries being connected to each other by conductors, the structure comprising:
an insulating substrate having openings facing the electrodes of the pair of adjacent batteries; a pair of connection terminals respectively connected to the electrodes of the pair of adjacent batteries through the openings in the insulating substrate by bolting with nuts; a pair of electric wires whose one ends are connected to the connection terminals respectively; and a connector connected to the other ends of the pair of electric wires, and detachably connected with the service plug, wherein the insulating substrate further comprises walls provided so as to face each other at a distance corresponding to a width of each of the connection terminals, the walls abutting against the connection terminals respectively, and regulating movement of the connection terminals which simultaneously rotate with rotation of the nuts respectively when being bolted with the nuts wherein each of the connection terminals are arranged in a space between the walls, and wherein ribs protrude from facing surfaces of the walls, and the connection terminals are arranged between the ribs and an installation surface of the insulating substrate where the connection terminals are installed.
