Description
Technical Field
The invention relates to a split charging and integral disassembling short-circuit protection device for a storage and transportation launching box, and belongs to the technical field of rocket.
Background
Rocket projectiles belong to dangerous initiating explosive devices, and need to carry out short-circuit protection on main engine ignition tools on the projectiles in the processes of storage, transportation and service in order to ensure safety and avoid accidental ignition. At present, the storage and transportation launching box is widely used, and an internal circuit of the rocket projectile is electrically connected with the rocket cannon through a box bottom electric connector. In order to ensure the circuit safety during the storage and transportation of the rocket projectile, a short-circuit protection device needs to be inserted into the electric connector to perform short-circuit protection on a main engine igniter of the rocket projectile. The short-circuit protection device generally adopts a standard electric connector with the tail end of a related contact pin short-circuited by a lead, but a double-cylinder structure with the inner cylinder of the standard electric connector directly moving and aligning and the outer cylinder fixed by knob inevitably influences the positioning of the inner cylinder due to the shielding of the outer cylinder on light, and causes the short-circuit failure due to difficult alignment and even no positioning under the combined influence of narrow bottom space of a box, insufficient illuminance and limited range of limb movement. Meanwhile, the tail end of the pin of the standard electric connector for welding the lead is in a blind hole structure or a round-off concave structure, and the lead is welded in a lap joint mode, so that cold joint is easily caused, or a welding spot is cracked in the transportation and vibration process, so that short circuit failure is caused. In addition, after the tail end of the lead is short-circuited in the standard electric connector, the short-circuit protection device and the engine igniter form a single-ring loop, when the igniter is accidentally connected with external power in series, although the potentials between the two electrodes of the igniter can be ensured to be equal, if the voltage is higher or the power-up time is longer, potential safety hazards also exist.
