An inertia cylinder restraint switch

Abstract

The invention discloses an inertial cylinder constrained switch, which belongs to the technical field of inertial switches. By correspondingly arranging a first inertial cylinder assembly, a moving electrode assembly, a static electrode assembly and a first locking piece in a switch body, the first inertial cylinder The corresponding setting of the component and the first locking member effectively realizes the effective locking when the switch is not working; and the corresponding setting of the locking spring in the moving electrode assembly makes the locking spring still in a compressed state after the moving electrode is matched with the static electrode, so that This is to achieve a reliable match between the dynamic and static electrodes. The inertial cylinder restraint switch of the present invention has a simple structure and is easy to set up, and can effectively realize accurate locking of the inertial switch when it is not working and reliable locking after matching, avoiding accidental triggering of the inertial switch, and ensuring storage and transportation of the inertial switch and reliability at work, which improves the working quality of the inertial switch, promotes the application and development of the inertial switch, and has a good application prospect and promotion 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...

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
