A split short-circuit protection device used for a storage, transport and launching tank

Abstract

The invention relates to a split-type short-circuit protection device used for a storage, transport and launching tank, belonging to the technical field of projectiles and rockets. The short-circuit protection device of the invention comprises a protection cap and a short-circuit body; Wherein the protective cap comprises a box cover, a spiral groove screw, a compression spring, a push rod, a spring, a screw plug and a push rod support; The short-circuit body includes a support frame, a conductive disk, a pin cushion, a pin, a pressing ring, and a long screw. The short-circuit protection device of the invention adopts a split structure of a short-circuit body and a protection cap, which ensures that the short-circuit protection device can be conveniently and quickly disassembled and assembled; The short-circuit body is clamped by the compression spring and the ejector rod inside the protective cap, which ensures the reliable conduction between all the pins and the conductive sheet. Theshort-circuit protection device of the invention has the advantages of reliable short-circuit effect and high safety.

Description

technical field [0001] The invention relates to a split-type short-circuit protection device 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 electrical...
