Safe separation mechanism used for missile electrical connecting piece

Abstract

The invention relates to a safe separation mechanism used for a missile electrical connecting piece. The safe separation mechanism comprises a mounting base and a guiding plate; separated tracks are formed in the guiding plate; fastening parts are arranged on the two sides of the mounting base; and the fastening parts are glidingly connected with the separated tracks. By adoption of the technical scheme provided by the invention, in the storage or transportation process of a ballistic missile, the electrical connecting piece is reliably connected with the mounting base; when the ballistic missile launches, the electrical connecting piece is separated from the mounting base quickly, reliably and automatically; meanwhile, ablation of the electrical connecting piece by hot air flow can be avoided, and enough safe distance is kept between the electrical connecting piece and the ballistic missile, so that launching of the ballistic missile is not affected; and the safe separation mechanism has the advantages of convenience in assembling, simple and convenient operation, simple structure, high reliability, low manufacturing cost and the like, and can be widely applicable to transverse electrical separation mechanisms of various kinds of launching boxes or launching cylinders.

[0002] With the development of the electric power industry, various electrical products are widely used in various fields of industry and civil use. Electrical connectors are currently the main electrical components used to connect electrical circuits, mainly including power plugs, power terminals, etc. These electrical connections The parts can be connected when they are in use, and they are generally disconnected manually when they are not in use. However, in some military industries and aerospace industries, due to the large shape and structure of the parts, it is necessary to use a larger puller The electrical connection can only be disconnected by force, or because the electrical connection is used in a very dangerous situation, the electrical connection cannot be directly disconnected manually. For example, the electrical connection used on ballistic missiles, in normal times It needs to be turned on so that the vacant circuit on the ballistic missile communicates with the underside launch control system, and when the ballistic missile is launched, it needs to be disconnected even if the electrical connection is separated. Inconvenient, the separation mechanisms used in the prior art for ballistic missile electrical connectors mainly include four-bar linkage separation mechanisms, shear separation mechanisms, electromagnetic separation mechanisms and electric separation mechanisms, etc., and the structures of these separation mechanisms are very complicated , takes up a lot of space, and the manufacturing cost is high. For example, the patent document with the publication number "CN106684638A" discloses a double positioning pin device for connector separation, which includes a front positioning pin, a rear positioning pin, a plug seat, and a connecting pin. The pole electric plug piece and the connecting rod electric plug piece are fixed with a plug seat, and the two ends of the plug seat surface are respectively fixed with a front positioning pin and a rear positioning pin; the front positioning pin includes a first ball head, a first positioning platform, and a first cylindrical section , the first threaded section, the first axis threading hole, the special-shaped guide post, the first cylindrical section and the special-shaped guide post are fixedly connected through the first positioning platform, the special-shaped guide post is provided with a first ball head, and the first cylindrical section is provided with There is a first axis threading hole, and the first cylindrical section is fixedly connected with the first threaded section through the first axis threading hole. Using the device provided by the invention, the lateral separation force when the missile is launched and separated is borne by the double positioning pins, which solves the problem of It solves the problem of damage to the insulating shell of the connector or the bending of the pins, eliminates the potential safety hazard during missile launch, and avoids the risk of launch. However, when the missile is separated, the connector does not maintain a sufficient safety distance after separation. , so there is still a risk of arcing between the electrical connectors after the missile is launched, and there are still some safety hazards
