Missile-borne self-locking inertia switch and method

Abstract

The invention discloses a missile-borne self-locking inertia switch and a method. The missile-borne self-locking inertia switch comprises a shell (1), a locking ring (2) is arranged in the shell (1), a locking channel (7) which is axially distributed is formed in the middle of the interior of the locking ring (2), a mass block (3) is arranged in the locking channel (7), and a locking mechanism matched with the mass block (3) is arranged in the locking ring (2); a contact plate component (6) located below the locking channel (7) is further arranged in the shell (1). The mass block provides pressing force for the lock spring through the lock bead, and when the mass block is subjected to overload impact, the mass block breaks through the pressing force of the lock bead and the lock spring, falls to the lowest point and compresses the contact plate component, and the triggering process is completed; and when the mass block is located at the lowest point, the lock bead resets under the action of the elastic force of the lock spring, so that the lock bead is in contact with the mass block, the mass block is fixed in a locked state, and self-locking is formed. According to the invention, not only is the locking function realized, but also the false triggering phenomenon can be effectively prevented.

Description

technical field [0001] The invention relates to an inertia switch, in particular to a bomb-loaded self-locking inertia switch and a method. 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. The fuze needs to judge that the warhead is in contact with the target, so as to give a detonating signal. The inertia switch is one of the commonly used components in triggering fuzes, and one of its functions is to control the working state of the circuit. The inertia switch is closed after feeling a certain overload shock generated during the launch or collision of the carrier, and sends a stable electrical signal to the fuze, and the fuze works after receiving the signal. Inertial switches are widely used in fuzes, especially in electromechanical fuzes, and are important components for elec...

AI Technical Summary

Problems solved by technology

However, the traditional inertial switch can only achieve instantaneous conduction, which leads to inaccurate control of the closing time of the inertial switch, and it is easy to cause false triggering in the case of non-triggering requirements such as transportation; moreover, the contact reliability of the existing inertial switch contacts Poor, easy to cause the carrier not to trigger

Therefore, the existing technology has the problems of no locking function and prone to false triggering
