Abstract

The utility model discloses an initiating explosive device directly ignited by high-energy primer external bridge fuse, which comprises a synchronous electric detonator, a delay electric detonator and an electric squib. The utility model is characterized in that the distance between a bridge fuse coated with a conductive film on the wire bridge fuse plug of the synchronous electric detonator, the delay electric detonator and the electric squib ranges from 1 to 3mm. The utility model adopts a KJ electrostatic discharge device as the initiating source so as to ensure that the bridge fuse explodes to ignite the detonator and the electric squib, so the utility model does not spontaneously explode when being stored or used and transported on the occasions where the static electricity and the stray current exist. If the product is stolen, the utility model can not be detonated without the special lighting system, for example, the lighting system provided with the common detonator can only ensure that the products of the utility model lose effectiveness without being detonated. The utility model has low cost and reliable safety performance.

Description

The priming system of high energy primer external bridge fuse

One, technical field

The utility model belongs to the priming system technical field, is specifically related to a kind of detonator and ignitron that adopts the direct-fire of high energy primer external bridge fuse, is the improvement to the sparking mode of existing electric cap and ignitron.

Two, background technology

The sparking mode of existing electric cap and squib has two kinds:

1, bridge silk pile things on is in the PbN6 priming, is the exploding bridge wire detonator of initiating source with 5KV voltage, 4 μ F electric capacity, electrostatic pulse below the 50J.As the nuclear bomb detonating capsule of China and the ARC-211 exploding bridge wire detonator of the U.S. all is the detonator of bridge silk in the electrostatic pulse primer.That but its used electrostatic pulse energy is the highest is 50J, so its range of application is very limited.This detonator is the special-purpose detonator of a section, and structure is special, and its caliber is 7.24mm, and pipe range is 13.5mm, and used lead is a coaxial cable, and length only is 152.4mm.The brisance of this detonator is lower than the power of No. 8 used detonators of explosion less than No. 6 detonators.The production cost of this detonator is very high in addition, and the ARC-211 detonator of the U.S. is 1.895 dollars every.The price of China's like product is up to 300 yuan every.

2, the bridge silk is wrapped in the middle of ignition charge or the priming, is the common electrical detonator and the ignitron of incendiary source with 1～1.5A power supply.The production cost of the said goods is about 1 yuan every, is fit to very much engineering explosion and uses.Also there is weak point in but this detonator: the one, and to be 5～8mm be subject to expansive force to payment to a porter length when pinching plug split off the bridge silk.The 2nd, the bridge silk is corroded by medicament, and resistance can increase or resistance break when long storage.The 3rd, the shape of the point of amorce that is coated with, size, quality all have difference, and it is bigger to cause ignition energy and time to go up difference.Especially assemble the ms delay detonator and super second phenomenon often occurs.The detonator that the most important thing is this structure in haulage, long storage, use and can rub, vibrate in production process and under the effect of static or stray electrical current, may produce the self-destruction phenomenon.

More than the electric cap of two kinds of different sparking mode and the common ground of squib be that its bridge silk all is directly to contact medicament, be referred to as the electric cap and the squib of bridge silk igniting in the medicine.

Three, summary of the invention

The purpose of this utility model provides a kind of priming system of high energy primer external bridge fuse, both solved 50J following vein and dashed, function singleness special and the high deficiency of cost, also solved long, unstable properties and have problem such as the potential safety hazard duration of ignition that common electrical detonator and ignitron exist simultaneously for the structure of the medicine implode bridge silk detonator of initiating source.

The utility model---the priming system of high energy primer external bridge fuse comprises synchronous electric cap, delay electric detonator and squib.Its characteristics are that the lead bridge silk of synchronous electric cap, delay electric detonator and squib scribbles powder charge in the bridge silk of conducting film and the shell beyond the Great Wall at a distance of 1～3mm.The bridge silk of electric cap, delay detonator and squib adopts the short payment to a porter welded bridge silk of 0.2～0.5mm synchronously.

The utility model is to adopt KJ level static discharge device to do initiating source, under the effect of high energy KJ level electrostatic pulse, makes the bridge silk blast that scribbles the antistatic conducting film, and detonator and ignitron are got angry.The utility model cost is low, and security performance is reliable, even deposit or use also and can not reveal in the occasion that has static and stray electrical current to exist; In transportation and handling process, be subjected to judder phenomenon also can not occur revealing; Stolen as product, can't not ignite because of there being this special sparking gear yet; As the sparking gear that uses plain detonator can only make stolen the utility model product failure and can not ignite.
