Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, and more specifically, to a waterproof connector for storage batteries. Background Art

[0002] A device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery; after discharge, the internal active substances can be regenerated by charging - the electrical energy is stored as chemical energy; when discharge is required, the chemical energy is converted into electrical energy again; this type of battery is called a storage battery (Storage Battery), also known as a secondary battery or lead-acid battery; the so-called storage battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

[0003] In traditional batteries, electrodes are usually fixed directly using copper wires, nuts, and screws. Some batteries are fixed with rubber sleeves to protect the electrodes. However, in the current situation, long-term use of the rubber sleeves will cause the electrodes to overheat and partially melt. Repair personnel will simply discard the rubber sleeves for convenience. After discarding the rubber sleeves, the battery electrode connection points are directly exposed to the air, creating opportunities for contact with various substances such as water and stains.

[0004] At present, the electrodes will become oxidized after long-term use. Once severely oxidized, it will cause leakage, false connection and other problems. Usually, the battery is directly replaced during the maintenance process, which results in high costs. Utility Model Content
