Universal inertia switch

Abstract

The invention discloses a universal inertia switch. The universal inertia switch comprises a shell assembly, an electrode structure and an insulating elastomer, the shell assembly is of a hollow structure; the electrode structure is mounted in the shell assembly; the insulating elastomer is filled between the shell assembly and the electrode structure; the electrode structure is an electrode for the universal inertia switch, is used for sensing overload signals with different directions greater than a threshold value, and is in contact with the other electrode on the shell assembly to close the switch; and the universal inertia switch can sense a positive axial overload signal, a negative axial overload signal, a radial overload signal and overload signals in other synthesis directions, and has a high adaptability.

Description

technical field [0001] The invention belongs to the technical field of inertial switches for fuzes, and in particular relates to a universal inertial switch. Background technique [0002] Conventional ammunition hard target warheads often use inertial trigger fuzes to detonate the warheads. When the warhead reaches the target area, the fuze completes all the release functions and is in a ready state. It is necessary for the fuze to judge that the warhead has touched the target, so as to give a detonation signal. [0003] The inertial switch is an important component commonly used in trigger fuzes. It can sense the shock overload generated by the triggering system hitting the target, close or disconnect the electrodes to give an electrical signal, and the fuze detonates the warhead in time according to the signal, completing the function of detonating the warhead. [0004] The traditional inertial switch mostly adopts a spring mass (shown in the patent document CN204558356U)...

AI Technical Summary

Problems solved by technology

These schemes often cannot take into account multiple directions. For example, the spring mass scheme can only sense the overload from one axial direction, but cannot sense the radial overload or the opposite axial overload signal; the cantilever beam mass scheme can only sense the radial overload, but cannot Feel positive and negative axial overload

Due to these deficiencies of the traditional inertial switch, when it is applied to trigger the fuze, it has high requirements on the angle of impact between the warhead and the target. Only when the angle of impact is met can the warhead be detonated in a timely manner. Satisfy complex projectile-target interaction conditions
