Further, the groove corner place of described middle cover is respectively arranged with a location hole, covers the alignment pin being provided with and matching with described location hole on described.
Further, the draw-in groove length for clamping bus-bar of the both sides horizontally set in the bottom of described middle cover is different.
Further, described draw-in groove and middle cover one-body molded.
Further, longitudinal air discharge duct is also communicated with in described transverse row air drain middle.
Further, described draw-in groove is groove.
The advantage that the present invention has and good effect are:
1, the present invention is due to without offset pole, thus can reduce internal resistance, and be connected more direct between battery electrode group with pole group, without extra plumbous part or lead vector, and can increase battery capacity, structure is simple, rationally distributed.
2, the upper cover in the present invention is connected with the groove of middle cover, and the face of groove-bottom is provided with transverse row air drain and longitudinal air discharge duct, above covers and is provided with the gas outlet corresponding with transverse row air drain and longitudinal air discharge duct, the gas overflowed can be discharged in safety valve.
3, the lid of lead acid accumulator provided by the invention eliminates offset pole, and after changing this structure, grid height generally can increase about 10 ~ 15mm, and corresponding active material increases relatively.Battery capacity is minimum increase by more than 10% on former basis.
4, storage battery middle cover seals junction with pole group's bus-bar, only need expand with bus-bar length bigger by draw-in groove length, mould relates to simply, retrofits conveniently in local.
