The present invention further improvement project is, the afterbody of described terminal is provided with the first welding hole, welding hole outside is provided with boss, welding hole inner side is provided with slotted eye, and at slotted eye end bending 90 degree upwards, then bending 90 degree inwardly, continue bending 90 degree downwards, bending 90 degree inwardly, are connected with terminal head again, are provided with the second welding hole on terminal head; The end of described terminal head is provided with chamfering; Described terminal head upwarps at an angle, with horizontal sextant angle be 5 °-45 °; The afterbody of described terminal is rounded or square.
The present invention compared with prior art, has following obvious advantage:
One, the present invention is because the middle cover one end at storage battery is provided with " E " type groove, anode and cathode terminals mates with groove, be sunken in middle cover, form the built-in accumulator structure of terminal, solve terminal in the past and exceed the drawback that capping brings, when battery stacks in battery case, avoid the anode and cathode terminals battery container of grinding away, and facilitate running in production cell process to stack.
Two, the present invention is provided with partition wall between two short slots of middle cover, forms " E " type storage battery middle cover, has avoided producing the battery plus-negative plate short-circuit of terminals because of misoperation.
Three, the present invention is provided with a plurality of longitudinal breach in middle cover location notch, produces the excessive glue phenomenon of terminal while effectively solving glue sealing, guarantees that battery outward appearance is clean and tidy.
