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 ax

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] Such as figure 1 As shown, a universal inertial switch, including:

[0027] a housing assembly; the housing assembly is formed as an internally hollow structure;

[0028] The electrode structure; the electrode structure is installed inside the housing assembly;

[0029] insulating elastomer 3; the insulating elastomer 3 is filled between the shell assembly and the electrode structure;

[0030] An electrode is connected to the shell assembly, and another opposite electrode is connected to the electrode structure;

[0031] When the switch is not subjected to the inertial overload exceeding the setting, when the switch is in the off state, the shell assembly does not make conductive contact with the electrode structure;

[0032] When the switch is subjected to an inertial overload in any direction exceeding the setting, when the switch is in the closed state, the in...

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)...
