Joint connector and busbar

A battery terminal includes a fastening portion () that is partially open in a circumferential direction and a flange () projects radially out from the fastening portion (). Two facing portions () project radially out from open ends () of the fastening portion () and face each other in the circumferential direction. The fastening portion () is reduced in diameter and fastened to a battery post P by having the facing portions () approach each other. The flange () of the fastening portion () has cuts () for partially reducing a thickness of the fastening portion () in a radial direction.

Battery terminal

A connector includes a first housing () with two detection terminals (), a resilient deflecting portion () in a second housing (), a shorting terminal fitting () in the second housing (), wiping portions () integrally formed to the shorting terminal fitting () and configured such that the detection terminals () slide in contact therewith in the process of connecting the first and second housings (), and a resilient contact piece () integrally formed to the shorting terminal fitting () and configured to be resiliently displaced to a retracted position, where the resilient contact piece is not in contact with the detection terminals (), as the resilient deflecting portion () is resiliently deflected and resiliently return to a short-circuit position, where the resilient contact piece contacts the detection terminals (), and short the detection terminals () as the resilient deflecting portion () resiliently turns.

Retainers () are exposed on an outer surface of the sub-housing () and are displaceable between a locking state for retaining terminal fittings () inserted into a sub-housing () and a separated state for allowing the terminal fittings () to be withdrawn from the sub-housing (). A frame () is formed with a holding portion () configured to hold the sub-housing () by being locked to the outer surface of the sub-housing () and openings () expose the retainers () with the sub-housing () held in the holding portion ().
