Locking type inertia switch

Abstract

The invention discloses a locking type inertia switch, and belongs to the technical field of inertia switches. With the corresponding arrangement of a movable electrode component, a static electrode component and a locking part, the separation of the movable electrode from the static electrode when the movable electrode does not work and the stable and reliable matching of the movable electrode and the static electrode when the movable electrode works can be effectively realized, and through the corresponding arrangement of the locking part, the situation that the moving electrode part can belocked at the working position by the locking part after the moving electrode is matched with the static electrode, can be effectively guaranteed, and the situation that the moving electrode part resets caused by the overload reduction or overload disappearance, is avoided. The locking type inertia switch is simple in structure, good in working accuracy and high in reliability, is simple and convenient to assemble, can effectively avoid the unstable matching of the moving electrode and the static electrode, and realizes the reliable locking of the moving electrode and the static electrode after the moving electrode and the static electrode are matched. Moreover, the inertia switch is many in number of cycles and long in service life, enables the service life to be reduced effectively, promotes the application of the inertia switch, and has the better practical value and popularization value.

Description

technical field [0001] The invention belongs to the technical field of inertia switches, and in particular relates to a latched inertia switch. Background technique [0002] Inertial switches have a wide range of applications in aerospace, automotive electronics, and ammunition. In general, the inertia switch is closed by the reaction force or the forward impulse inertia force when the carrier hits the target, and realizes the function of the circuit from disconnection to connection. Inertial switches are widely used in fuzes, especially in electromechanical fuzes, and are important components for electromechanical fuzes to trigger detonation or self-destruct on the ground. [0003] At present, most of the existing inertia switches adopt a combined structure of a spring and a mass block. The spring and the mass block are used as movable electrodes and correspond to a fixed electrode separately provided and separated from the movable electrode at a certain distance. When th...

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
