Conductor module attachment structure

1. A conductor module attachment structure comprising:

a case that includes a connection conductor for electrically connecting a plurality of single batteries;

a recessed groove that is provided protrusively on an outer wall of the case and extends along the outer wall;

a protector that extends along the recessed groove and is formed into a U-shape in section perpendicular to a longitudinal direction of the protector so as to have a U-groove and that is configured that an opening portion of the U-groove of the protector is closed by an inner wall face of the recessed groove when the protector is inserted into the recessed groove;

a voltage detecting line that is routed in the U-groove of the protector;

a voltage detecting terminal that is connected to one end of the voltage detecting line; and

a terminal retaining portion that is provided on the protector and that leads the one end of the voltage detecting line out of the U-groove of the protector in the recessed groove and positions the voltage detecting terminal contactably with the connection conductor.

2. The conductor module attachment structure according to claim 1 , wherein a positioning rib that extends in an insertion direction of the protector into the recessed groove is provided protrusively on the recessed groove; and

wherein a positioning recess that is configured to engage with the positioning rib to position an attachment position of the protector relatively to the case is provided on the protector.

3. The conductor module attachment structure according to claim 1 , wherein a jumping-out restraining claw that restrains the routed voltage detecting line from jumping out is provided at the U-groove in the protector.

4. The conductor module attachment structure according to claim 1 , wherein a lock mechanism which restrains the protector from separating from the recessed groove is provided between the case and the protector.
