Inertia cylinder constraint type switch

Abstract

The invention discloses an inertia cylinder constraint type switch, and belongs to the technical field of inertia switches. The inertia cylinder constraint type switch is characterized in that a firstinertia cylinder assembly, a movable electrode assembly, a static electrode assembly and a first locking piece are correspondingly arranged in a switch body, and the effective locking of the switch when the switch does not work is effectively realized by utilizing the corresponding arrangement of the first inertia cylinder assembly and the first locking piece; by utilizing the corresponding arrangement of a locking spring in the moving electrode assembly, the locking spring is still in a compressed state after a moving electrode is matched with a static electrode, so that the reliable matching between the moving electrode and the static electrode is realized. The inertia cylinder constraint type switch is simple in structure, is simple and convenient to set, can effectively realize the accurate locking of the inertia switch when the inertia switch does not work and the reliable locking after matching, avoids the accidental triggering of the inertia switch, guarantees the reliability of the inertia switch during storage, transportation and work, improves the work quality of the inertia switch, promotes the application and development of the inertia switch, and has better application prospects and popularization value.

Description

technical field [0001] The invention belongs to the technical field of inertia switches, and in particular relates to an inertia cylinder restraint switch. Background technique [0002] In the fields of aerospace, automotive electronics and ammunition, inertial switches have a very wide range of applications. In general, the inertial switch is closed by the reaction force or forward inertial force when the carrier hits the target, so as to realize the function of switching the circuit from disconnection to connection. Inertial switches are widely used in fuzes, especially electromechanical fuzes, and are important components for electromechanical fuzes to achieve trigger detonation or self-destruct functions on landing. [0003] At present, most of the existing inertial switches adopt a combined structure of a spring and a mass block. The spring and the mass block are used as movable electrodes, which correspond to the fixed electrodes which are separately arranged at a cer...

AI Technical Summary

Problems solved by technology

Although the above-mentioned inertial switch can meet the needs of use to a certain extent, it also has certain defects, mainly because the above-mentioned inertial switch often bounces off the mass block after the mass block collides with the fixed electrode, resulting in inaccurate control of the closing time of the inertial switch , and the contact reliability of the contacts is poor

In addition, in some products, in order to prevent accidental impact, it is often necessary to realize self-locking after the switch is closed to ensure the continuous and stable power connection of the switch and the stable operation of the power supply and load circuit, but this uses the existing inertial switch Often difficult to achieve, so that the application of the above products is limited
