Lead storage battery equipped with terminal protection cover

Abstract

The invention discloses a lead storage battery equipped with a terminal protection cover. The lead storage battery comprises a groove body, a groove cover and wiring terminals mounted on the groove cover; a lug boss is arranged on the top surface of the groove cover; a cover sheet groove is formed in the lug boss; an electrolyte injection hole column is arranged in the cover sheet groove; concave parts for avoiding the wiring terminals are formed in the side surface of the lug boss; the free ends of the wiring terminals extend to exceed the groove cover edge; a right-angle type protection cover is arranged above the wiring terminals; a horizontal edge plate of the protection cover is matched with the concave parts and is flush with the lug box in a jointing manner; a vertical edge plate of the protection cover is connected with the groove body or the groove cover through a bolt; and the inner side surface of the protection cover is attached to the free ends of the wiring terminals in a propping manner. The protection cover of the lead storage battery provided by the invention can protect the wiring terminals, so that short circuit caused by mistake contact between a conductive body and the positive wiring terminal or the negative wiring terminal in a storage, transfer and a use process carelessly can be avoided; and meanwhile, the lead storage battery is convenient to use, attractive in appearance, and convenient to stack, store and transfer.

Description

Technical field [0001] The present invention relates to the technical field of lead storage battery production, in particular to a lead storage battery with a terminal protective cover. Background technique [0002] A battery is a device that directly converts chemical energy into electrical energy. It is a battery designed for rechargeability. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery. It is a type of battery and belongs to the secondary battery. Its working principle: When charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and convert chemical energy into electric energy again when it needs to be discharged. [0003] A battery generally includes a positive plate, a negative plate, a separator, an electrolyte, a bus bar, a positive pole, and a negative pole. Among them, the positive plate and the negative plate are the core components of the battery, and ...
