Technical Field

[0001] The utility model relates to the technical field of insulating terminals, in particular to an insulating terminal for a car battery. Background Art

[0002] The working principle of a car battery is to convert chemical energy into electrical energy. Usually, a car battery refers to a lead-acid battery, which is made of lead and its oxides, and the electrolyte is a sulfuric acid solution. During the discharge process, the lead at the negative electrode reacts with the sulfuric acid in the electrolyte to produce lead sulfate and water, and release electrical energy; while during the charging process, the opposite reaction occurs, converting the electrical energy into chemical energy for storage. When the car battery is connected to other electrical appliances, the terminal is used for electrical connection. However, most of the terminals of the car battery are currently connected by a press-fit connection with a nut, which means that when the car battery needs to be disconnected from the electrical appliance, the nut needs to be unscrewed and the connecting wire needs to be removed. The operation is cumbersome and it is difficult to achieve the purpose of quick power off.
