Inter-battery connection device and inter-battery connection device assembly

An inter-battery connection device for connecting electrode terminals of a plurality of batteries comprising:

• a housing;
• a bus bar attached to the housing and electrically connecting two electrode terminals of a pair of batteries adjacent to each other, the bus bar including a pair of clips each contacting one electrode terminal and a coupling portion connecting the pair of clips;
• and
• a movable member movable between a temporary catching position attached to the housing and a final catching position attached to the housing, the movable member having a clip contact avoiding portion preventing contact between one of the clips and the electrode terminal in the temporary catching position and permitting contact between the clip and the electrode terminal during movement from the temporary catching position to the final catching position,
• wherein the movable member has a pair of cantilever-type temporary catching arms and a final catching arm.

An inter-battery connection assembly for connecting electrode terminals of a plurality of batteries, comprising:

• a plurality of inter-battery connection devices, each inter-battery connection device including:
• a housing, the housings of inter-battery connection devices adjacent to each other are coupled to each other;
• a bus bar attached to the housing and electrically connecting two male-type tab electrode terminals of a pair of batteries adjacent to each other, the bus bar including a pair of clips each contacting one electrode terminal and a coupling portion connecting the pair of clips;
• and
• a movable member movable between a temporary catching position attached to the housing and a final catching position attached to the housing, the movable member having a clip contact avoiding portion including a protrusion having a portion with a width greater than a plate thickness of the tab terminal for preventing contact between one of the clips and the electrode terminal in the temporary catching position and permitting contact between the clip and the electrode terminal during movement from the temporary catching position to the final catching position.
