Description
technical field [0001] The invention relates to a disassembled short-circuit protection device used for storing and transporting launch boxes, and belongs to the technical field of bullets and arrows. Background technique [0002] Rockets are dangerous pyrotechnics. In order to ensure safety and avoid accidental ignition, the main engine igniter on the rocket needs to be short-circuit protected during storage, transportation and service. At present, the storage and transportation launch box is widely used, and the internal circuit of the rocket is electrically connected to the rocket launcher through the electrical connector at the bottom of the box. In order to ensure the safety of the circuit during storage and transportation of the rocket, it is necessary to install a short-circuit protection device on the electrical connector to provide short-circuit protection for the main engine igniter of the rocket. The short-circuit protection device generally adopts a standard ele...
