Problems solved by technology

[0003] Since the fuze is threadedly connected to the projectile body, in order to ensure the connection strength, the number of turns of the thread is large, which leads to the problem of time-consuming and laborious assembly process; in addition, in the recovery fuze in the bombing test, the thread fails due to the deformation of the projectile body, so there are many problems. It is difficult to disassemble the fuze, and the deformation of the projectile will squeeze the fuze, causing most of the fuze to be damaged, and the problem of recovery of the fuze is not used; in addition, due to the high rigidity of the threaded connection structure, the attenuation and filtering effect on the stress wave is weak, and the high overload The transmission of the signal to the interior of the fuze can easily cause the failure of the electronic components of the fuze due to vibration

Abstract

The invention provides a projectile-fuse connection structure and an initiation device, and relates to the technical field of initiation. The projectile-fuse connection structure comprises a projectile body, a fuse and a fuse pressing ring. A mounting hole is formed in the projectile body, and the fuse pressing ring is configured to crimp the fuse in the mounting hole, and a gap between the peripheral wall of the fuse and the peripheral wall of the mounting hole is formed. The initiation device comprises the projectile-fuse connection structure. The technical problems that assembling process is time-consuming and laborious and the fuse is difficult to disassemble due to the fact that the fuse is in threaded connection with the projectile body, the fuse is mostly damaged and the recovery ofthe fuse is not favorable due to the fact that the deformation of the projectile body squeezes the fuse, and the fuse lose efficacy due the fact that electronic components of the fuse are prone to vibrating are solved.

Description

technical field [0001] The invention relates to the technical field of detonation, in particular to a spring-induced connection structure and a detonation device. Background technique [0002] In the field of detonation, the fuze system of domestic aviation-guided bombs is mainly to connect the fuze to the tail end of the bomb body and use the power supply on the bomb. When the aerial bomb hits the target, the stress wave generated by the impact passes through the threaded connection. It is transmitted to the fuze, and an acceleration sensor is arranged in the fuze. The acceleration sensor senses the overload signal and gives an electrical signal instruction, and then the fuze sends a detonation instruction to detonate the booster charge. [0003] Since the fuze is threadedly connected to the projectile body, in order to ensure the connection strength, the number of turns of the thread is large, which leads to the problem of time-consuming and laborious assembly process; in ...
