Cover body of lead-acid storage battery

Abstract

The invention provides a cover body of a lead-acid storage battery. The cover body comprises a middle cover and an upper cover, wherein a positive electric connection hole and a negative electric connection hole are formed in the bottom end of the middle cover; bulges cover the positive electric connection hole and the negative electric connection hole; clamping grooves for clamping busbars are transversely formed in two sides of the bottom end of the middle cover; a plurality of safety valves, a groove for accommodating the upper cover, transverse exhaust grooves and a plurality of longitudinal exhaust grooves are transversely arranged on and formed in the upper end of the middle cover; the safety valve and single pole groups of the storage battery are correspondingly arranged; the transverse exhaust grooves are respectively connected with the safety valve; the longitudinal exhaust grooves are correspondingly connected with the safety valve respectively; and air outlets which correspond to the transverse exhaust grooves and the longitudinal exhaust grooves are respectively formed in the side surface of the upper cover. The cover body of the lead-acid storage battery has the beneficial effects that the shell cover structure of the battery is changed; and the size of a plate grid is increased under the condition that the boundary dimension of a battery jar is fixed, so that the capacity of a capacitor is increased.

Description

technical field [0001] The invention belongs to the technical field of accumulators, in particular to a cover body of a lead-acid accumulator. Background technique [0002] The capacity of the battery is one of the important performance indicators of the battery performance. It indicates the amount of electricity released by the battery under certain conditions (discharge rate, temperature, end voltage, etc.), usually in units of ampere and hour (abbreviated as A.H). The higher the battery capacity, the longer the discharge time under certain conditions. There are many technical parameters that determine battery capacity, one of which is the amount of active material. The factor that determines the amount of active material is determined by the volume of the grid. In the prior art, the positive busbar and the negative busbar are connected by the bias pole. In the case, the structure of sealing the bias pole after the shell cover is buckled determines the height of the bus ...

AI Technical Summary

Problems solved by technology

The factor that determines the amount of active material is determined by the volume of the grid. In the prior art, the positive busbar and the negative busbar are connected by the bias pole, which requires a structure for sealing the bias pole at the shell cover, and the pole group is placed in the groove. In the case, the structure of sealing the bias pole after buckling the cover determines the height of the busbar to the bottom, which limits the height of the plate and the capacity of the battery
