Preferably, the length of the connector is not less than the width of lug, and the no more than length of 1/2 cover plate, the appearance
Receive portion width be not less than lug thickness.
Preferably, described accommodation section includes two side walls.
Preferably, described accommodation section also includes position block, the position block respectively with the end face, two
The individual side wall is vertical.
Preferably, the connector is made up of metal material.
A kind of attachment structure of soft pack cell lug and cover plate, connector described in any of the above, the lug stretches into lug
Receiving portion, the lug and at least one described side wall by together with spot-welded, the electrode terminal through cover plate and to
The opposite direction extension of lug receiving portion.
Preferably, lug is abutted in the end face.
Preferably, it is characterised in that also including electrode terminal fixture, the electrode terminal fixture is consolidated with electrode terminal
It is fixed to weld and fitted with cover plate.
Preferably, the cover plate is made up of metal material, and the connector, fixture are fixed with absolutely between cover plate respectively
Edge layer.
The utility model devises the connector and attachment structure of a kind of soft pack cell lug and cover plate, can accurately determine
Position, and the contact area of lug and connector is big, welding effect is good, has prevented lug and has come off the phenomenon of rosin joint, and sequencing is strong,
Efficiency high.
