Description

A kind of fuse touching switch

Technical field

The utility model relates to the switch of fuse, is specifically related to a kind of fuse touching switch.

Background technology

Touching switch is as the term suggests being the unlatching or the cut out that are realized switch by touching, and touching switch is the important component part of fuse, and its main function is that fuze circuit can be connected instantaneously after body hits target, ignites blasting cartridge. Mass force, atmospheric drag can not be overcome, it is easy to the phenomenon that turning circuit detonates voluntarily occurs in touching switch is with the process of aircraft flight.

Practical novel content

For solving the problems of the technologies described above, the utility model provides a kind of fuse touching switch, the stage clip of this fuse touching switch needs to overcome mass force, atmospheric drag in flight course, in guarantee flight course, turning circuit does not detonate voluntarily, and when when touching head touching ground, forward momentum reaches certain value simultaneously, the reliable turning circuit of touching switch energy detonate.

The utility model is achieved by the following technical programs.

A kind of fuse touching switch that the utility model provides, comprises touching head, touching bar assembly, housing, stage clip, block and ejector pin component; The inner chamber on described housing top loads touching head, stage clip and block successively, and block is fixedly connected with the inwall of touching head; Being fixedly connected with the top of housing after the through hole of the union lever upper end of described touching bar assembly on block, the lower end of union lever is fixedly installed conduction column; Described ejector pin component is fixed on the lower end of housing by web plate, and two touching thimbles of ejector pin component are placed in the underface of conduction column and the compressible stroke that the distance between two touching thimbles and conduction column is less than between touching head and block.

Described conduction column is copper post.

Two touching thimbles of described ejector pin component are welded on insulating mounting plate, and insulating mounting plate is fixed by screws on web plate.

Described two touching thimbles are also arranged with insulating mounting seat.

Described insulating mounting plate is printed board.

Described union lever is plastics double end studs.

Described two touching thimbles are elasticity part.

The beneficial effects of the utility model are: the stage clip of touching switch needs to overcome mass force, atmospheric drag in flight course, ensure that in flight course that turning circuit does not detonate voluntarily, when when touching head touching ground, forward momentum reaches certain value simultaneously, touching switch can detonate by reliable turning circuit, the utility model structure is simple, easy to assembly, with low cost, is applicable to the products for civilian use such as fire-fighting bomb for forest fuse.

Embodiment

Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.

A kind of fuse touching switch as shown in Figures 1 to 3, comprises touching 1, touching bar assembly 2, housing 3, stage clip 4, block 5 and ejector pin component 6; The inner chamber on described housing 3 top loads touching 1, stage clip 4 and block 5 successively, and block 5 is fixedly connected with the inwall of touching 1; Being fixedly connected with the top of housing 3 after the through hole of union lever 21 upper end of described touching bar assembly 2 on block 5, the lower end of union lever 21 is fixedly installed conduction column 22; Described ejector pin component 6 is fixed on the lower end of housing 3 by web plate 65, two touching thimbles 61 of ejector pin component 6 are placed in the underface of conduction column 22, and the distance between two touching thimbles 61 and conduction column 22 is less than the compressible stroke of touching between 1 and block 5.

Described union lever 21 is plastics double end studs; Described conduction column 22 is copper post.

Two touching thimbles 61 of described ejector pin component 6 are welded on insulating mounting plate 63, and insulating mounting plate 63 is fixed on web plate 65 by screw 64; Described two touching thimbles 61 are also arranged with insulating mounting seat 62; Described insulating mounting plate 63 is PCB printed board. The head of touching 1 is circular arc, and touching bar assembly 2 adopts part between nonmetal union lever 21 and conduction column 22 to be connected, and mount pad 62 is non-metallic material, and described two touching thimbles 61 are elasticity part, touching thimble 61 bottom welding wire 7.

Fuse of the present utility model touching switch, is positioned at the head of fuse, is also the head being in body. Body is at mission phase, touching switch can overcome mass force and the atmospheric drag that touching head is produced by engine thrust under the effect of stage clip, the copper post ensureing to touch in flight course bar does not contact with touching thimble, the circuit of fuse is in disconnection state, when body is born, touching head touching ground touch when impact force reaches certain value head compression press spring make the copper post on touching bar with two touching thimbles contact and compress make fuze circuit conducting ignition blasting cartridge. The utility model structure is simple, easy to assembly, with low cost, is applicable to the products for civilian use such as fire-fighting bomb for forest fuse.
