Abstract
The utility model relates to a double-igniter-wire electric igniter. The double-igniter-wire electric igniter comprises a shell, wires, igniter wires and an ignition medicament block, wherein the ignition medicament block is accommodated in the shell, the igniter wires are connected with one ends of two wires respectively and are embedded in the igniter medicament block, and the other ends of the wires stretch out of the igniter medicament block; the number of the igniter wires is not less than two, and the igniter wires are connected at one ends of the two wires in parallel. Due to the adoption of the double-igniter-wire structure, the phenomenon that ignition can be normally carried out once one igniter wire is broken is prevented, and effect caused by external using environment factors is avoided, because the two igniter wires work at the same time, ignition reliability is high; because the shell does not deform, the igniter wires and medicaments are prevented from being damaged in the secondary using and assembling process of the shell; a high-temperature plastic sealing piece prevents plastic on the surfaces of the wires from melting in the ignition process and affecting the ignition effect; because the two wires are not mutually wound and certain intervals are reserved between the two wires, the igniter wires will not be in an on-state when being too close after the igniter wires are fused; accordingly, when the electric igniter works, the two wires are in an open-circuit state.
Description
Technical field
The utility model relates to electric initiator, more particularly, relates to a kind of doube bridge silk electricity initiator.
Background technology
The electricity initiator, also be electric igniter, is to set off, ignite that industry occurs at most, the most general product.Generally by wire, bridge silk, gunpowder (or other inflammable medicaments, igniting medicine), protective layer, formed at present.
Current electric igniter on the market, it is an accessory of final products, ubiquity reliability, the inconsistent problem of stability, especially in the production process of whole product, meeting is not suitable with the production technology characteristic of portioned product to electric igniter generation secondary destruction or electric igniter.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of reliability is high, stability is strong, can effectively prevent the doube bridge silk electricity initiator that secondary destroys
The technical solution of the utility model is as follows:
A kind of doube bridge silk electricity initiator, comprise shell, wire, bridge silk, ignition powder piece, and the ignition powder piece is filled in shell, and the bridge silk connects an end of two wires, and is embedded in the ignition powder piece, and the other end of wire stretches out outside the ignition powder piece; Described bridge silk has at least two, is an end that is connected in parallel on two wires.
As preferably, in shell, an end that stretches out wire is filled with seal.
As preferably, two wires are not wound around mutually.
As preferably, between two wires, there is interval.
As preferably, the housing of deformation for not occurring in described shell.
The beneficial effects of the utility model are as follows:
1, doube bridge silk structure, but prevent one of them bridge silk also normal ignition that broken;
2, doube bridge silk structure, prevent that two root bridge silks are worked simultaneously because of outside environment for use factor impact, and the igniting reliability is high;
3, the shell of deformation does not occur, and prevents bridge silk, the medicament of breakdown point duration and degree of heating in secondary use, assembling process;
4, high temperature plastics seal, prevent that plain conductor surface plastics from having affected the igniting effect in the ignition process thawing;
5, two wires, be not wound around mutually, and certain interval is arranged, and after the fusing of bridge silk, can not answer two wires too near and in on-state; Thereby, after electric initiator work, two wires are in open-circuit condition.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: the 1st, shell, the 2nd, wire, the 3rd, bridge silk, the 4th, ignition powder piece, the 5th, seal.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of doube bridge silk electricity initiator, comprise shell 1, wire 2, bridge silk 3, ignition powder piece 4, ignition powder piece 4 is filled in shell 1, bridge silk 3 connects an end of two wires 2, and is embedded in ignition powder piece 4, and the other end of wire 2 stretches out outside ignition powder piece 4.
For prevent because of bridge silk 3 fracture causes can not normal ignition, prevent from improving the Stability and dependability of electric initiator work because of outside environment for use factor impact, described bridge silk 3 has at least two, is an end that is connected in parallel on two wires 2.In the present embodiment, described bridge silk 3 is two.
In order to prevent, after 3 fusing of bridge silk, too near in on-state because of two wires 2, so, in the utility model, two wires 2 are not wound around mutually, there is interval in two 2, wires.Thereby, after electric initiator work, two wires 2 are in open-circuit condition.
In order to prevent bridge silk 3, the ignition powder piece 4 of breakdown point duration and degree of heating in secondary use, assembling process, the housing of deformation for not occurring in described shell 1.In the present embodiment, described shell 1 is metal shell 1, is difficult for deformation occurs, and can protect well bridge silk 3 and ignition powder piece 4.
In order to prevent that the surperficial plastics of wire 2 from melting and having affected the igniting effect in ignition process, in shell 1, an end that stretches out wire 2 is filled with seal 5.In the present embodiment, described seal 5 is high temperature plastics seal 5.
Operation principle of the present utility model is:
Above-described embodiment is only for the utility model is described, and not with the restriction of the present utility model of opposing.So long as according to technical spirit of the present utility model, to above-described embodiment changed, modification etc. all will drop in the scope of claim of the present utility model.
Claims (5)
1. a doube bridge silk electricity initiator, comprise shell, wire, bridge silk, ignition powder piece, and the ignition powder piece is filled in shell, and the bridge silk connects an end of two wires, and is embedded in the ignition powder piece, and the other end of wire stretches out outside the ignition powder piece; It is characterized in that, described bridge silk has at least two, is an end that is connected in parallel on two wires.
2. doube bridge silk electricity initiator according to claim 1, is characterized in that, in shell, an end that stretches out wire is filled with seal.
3. doube bridge silk electricity initiator according to claim 1, is characterized in that, two wires are not wound around mutually.
