Problems solved by technology
During the battery short-circuit test, the battery current is very large, some tens of amperes or hundreds of amperes, and the battery is easy to catch fire and explode, which has a great impact on the life safety of testers
However, in the existing battery short-circuit test process: the tester directly welds the two ends of the battery with a wire, and directly short-circuits the other end of the wire.
When the short-circuit current is too large, the solder melts and the wires are separated from both ends of the battery, resulting in test failure. If you want to test, the tester needs to re-solder the battery, which is a waste of time, and the battery that has been short-circuited is prone to explosion
At the same time, the testers are close to the test battery, and the explosion of the battery will endanger personal safety

A battery short circuit testing device comprises a protection shell, two sliding blocks, two ejector pins, two elastic elements, a relay and s controller, wherein the two sliding blocks are arranged in the protection shell in a relative sliding mode, the two ejector pins are slidingly arranged on the two sliding blocks respectively, the ejector pins are oppositely arranged, each elastic element is clamped between one ejector pin and the corresponding sliding block, the two ejector pins are respectively and electrically connected to a movable contact and a fixed contact of the relay, and the controller is electrically connected with the relay and controls connection / disconnection of the movable contact and the fixed contact of the relay. According to the invention, the two poles of a battery can be abutted against the two ejector pins and connection / disconnection of the two poles of the battery is controlled through the relay, soldering is not required, and the reliability of testing is improved.
Description
technical field [0001] The invention relates to battery testing, in particular to a battery short-circuit testing device. Background technique [0002] Lamps can be seen everywhere in modern society, and the lamps used in all walks of life have different purposes. However, in the production of lamps, especially battery discharge lamps, there is a high reliability requirement on the performance of the battery. [0003] Before the battery leaves the factory, it is necessary to do some safety tests on the battery. The short circuit test of the battery is an important safety indicator of the battery test. During the battery short-circuit test, the battery current is very large, some tens of amperes or hundreds of amperes, and the battery is easy to catch fire and explode, which has a great impact on the life safety of testers. However, in the existing battery short-circuit test process: the tester directly welds the two ends of the battery with a wire, and directly short-circu...
