Spacer for storage battery post terminal

The utility model provides a spacer for a storage battery post terminal. The spacer comprises a conductive body, wherein the body is provided with a cavity connected to the storage battery post terminal in a sleeving manner, two conductive electric connectors are arranged on the outer surface of the body in an extending way, and each electric connector is provided with a joint connected with a lead-out circuit of a voltage acquisition loop/load loop. With implementation of an embodiment of the utility model, under the condition that a security coefficient and contact resistance of a joint of a storage battery post are not reduced, the single spacer can be connected with dual loops (namely the voltage acquisition loop and the load loop), can reduce errors caused by connection resistance of a test loop and can achieve the aims of high measurement accuracy and small errors.
