Abstract

A conductor unit includes a connection conductor directly or indirectly connected with at least one electrode terminal in an electrode terminal group of a plurality of battery cells arranged in the same direction, a linear conductor connected with a battery monitoring unit that monitors the battery conditions of the battery cells, a fusible body that is connected between the connection conductor and the linear conductor and fuses when an overcurrent flows between the connection conductor and the linear conductor, and an insulative resin-molded member that contains the fusible body therein. The connection conductor includes holding portions that are disposed inside the resin-molded member, and hold the resin-molded member. The holding portions are formed in at least two places spaced apart from each other.

First claim

What is claimed is:

1. A fixing structure of a conductor unit comprising:
a connection conductor that is connected directly or indirectly with at least one electrode terminal in an electrode terminal group of a plurality of battery cells arranged in a same direction;
a linear conductor connected with a battery monitoring unit configured to monitor the battery conditions of the battery cells;
a fusible body that is connected between the connection conductor and the linear conductor, the fusible body being configured to fuse when an overcurrent flows between the connection conductor and the linear conductor; and
an insulative resin-molded member that contains the fusible body inside the insulative resin-molded member, wherein
the connection conductor includes holding portions that are disposed inside the resin-molded member and hold the resin-molded member,
the holding portions are formed in at least two places spaced apart from each other,
the holding portion is formed in a plate-like shape, and provided with at least one through hole, and
a part of the resin-molded member is disposed inside the through hole.

2. The fixing structure of the conductor unit according to claim 1 , wherein
each of the holding portions projects in a direction orthogonal to the arrangement direction of the battery cells, and at least one of the holding portions serves as a connection portion configured to electrically connect the fusible body and the connection conductor with each other.

3. The fixing structure of the conductor unit according to claim 1 , wherein
the resin-molded member is formed in such a manner that an outside bottom surface of the resin-molded member facing the battery cells is located coplanar with a side face of the battery cells or located on a side opposite to the battery cells with respect to the side face of the battery cells, in a state where the connection conductor is connected with the electrode terminal.

4. The fixing structure of the conductor unit according to claim 2 , wherein
the resin-molded member is formed in such a manner that an outside bottom surface of the resin-molded member facing the battery cells is located coplanar with a side face of the battery cells or located on a side opposite to the battery cells with respect to the side face of the battery cells, in a state where the connection conductor is connected with the electrode terminal.
