In the electric igniter for the automobile air bag restraint system, provided by the invention, due to the insulation of the pipe shell, when a product is welded for packaging, relative high welding energy can be adopted, the welding connection between the pipe shell and an electrode base is ensured to be firm, welding light beam or energy can be ensured to be effectively isolated with the powders inside the powder pipe, and thus, the probability of false explosion generated due to heated powder is reduced and the safety of a production process is improved.
Description
Technical field
The present invention relates to a kind of auto parts and components, particularly a kind of safe automobile air bag electric igniter.
Background technology
Electric igniter in the market mainly contains the product of two kinds of patterns, and a kind of is plastic construction, and a kind of is metal construction.
Plastic construction has not been suitable for new type of safe air bag gas generator product, so though its cost is low, and field of application is too narrow, do not have the market competitiveness because the intensity of self is low.
The metal electric igniter is except the intensity height, and the performance ratio plastic product is more superior, can be fit to the requirement of all automobile safety air bag gas generators.But all connecting bridges of metal electric igniter all are metallic materials; So the seal aspect at product just adopts a lot of welding manners; Because welding can produce very high temperature; And the igniter of the inside dress is easy to blast, and the safety during welding just becomes the important control point of production, and production facilities need invest considerable capital to transform.
Summary of the invention
The object of the present invention is to provide a kind of light beam of welding or energy of having guaranteed effectively to isolate, reduced medicament and be heated and the probability of mistake blast take place, the safe automobile air bag electric igniter of the safety of raising production process with the inner medicament of being adorned.
Safe automobile air bag electric igniter of the present invention comprises: ring electrode; Insulating glass is arranged between the said ring electrode; Single electrode is divided into first single electrode and second single electrode, and said first a unipolar end is connected with said ring electrode; Said second single electrode inserts in the said insulating glass; The bridge silk links together said ring electrode and said second single electrode through it; Shell is connected with said ring electrode, and said shell and said ring electrode and said insulating glass form a space; Igniter is arranged in the said space; Plastic jacket is arranged on the outside of said shell; Plastic injection-moulded body is arranged on the outside of said plastic jacket and said ring electrode; In said space, be provided with pencil, said pencil is connected with the side of said ring electrode away from the axle center.
The end away from ring electrode at said pencil is provided with the bending of pointing to the axle center; Centre in said bending is set to hollow out; Said pencil and said shell are fixed on the said ring electrode through the mode of laser welding; One end of said shell is provided with weak groove; Said shell is the cup-shaped stainless steel structure; Said plastic jacket and said plastic injection-moulded body are nylon material; Said plastic injection-moulded body forms through mold injection; Said plastic jacket is the cup-shaped moulding; The material of said bridge silk is Q alloy or platinum tungsten.
Safe automobile air bag electric igniter of the present invention is in the structure of product, to increase a pencil newly; Through the isolation of pencil, make product when carrying out welded encapsulation, can not only adopt high relatively welding energy; Guarantee firm welding between shell and the electrode holder; The light beam or the energy that have also guaranteed welding can effectively be isolated with the inner medicament of being adorned, and have reduced medicament and have been heated and the probability of mistake blast take place, the safety of raising production process.Because the existence of pencil is arranged, enrich the filling technology of medicament simultaneously, also improved the efficient and the precision of filling medicine.

The specific embodiment
Below in conjunction with accompanying drawing safe automobile air bag electric igniter of the present invention is done further explain.
As shown in Figure 1, safe automobile air bag electric igniter of the present invention comprises: ring electrode 2; Be arranged on insulating glass 11 between the ring electrode 2; One end of first single electrode 9 and second single electrode, 10, the first single electrodes 9 is connected with ring electrode 2, and second single electrode 10 inserts in the insulating glasses 11, and first single electrode 9 and second single electrode 10 be direct contact not each other; The material that is arranged on the ring electrode 2 is the bridge silk 7 of Q alloy; Through bridge silk 7 first single electrode 9 and second single electrode 10 are linked together; Play and between first single electrode 9 and second single electrode 10, form an electric bridge; In electric igniter, rise electric energy is changed into heat energy, the effect of flashpoint gunpowder 8.
The mode and the ring electrode 2 bonded assembly shells 5 of laser welding are passed through at two ends respectively; One end of shell 5 is provided with weak groove 13; Shell 5 is the cup-shaped stainless steel structure, plays seal point gunpowder 8, avoids it when long term storage, to make moist and the effect of the conduction orientation of pilot point gunpowder 8 explosion time heats; Shell 5 forms a space with ring electrode 2 and insulating glass 11, is used to store igniter 8; In the space, also be provided with pencil 3, pencil 3 two ends are being connected away from axle center one side with the mode of ring electrode 2 through laser welding, and pencil 3 is provided with the bending 4 of pointing to the axle center at the end away from ring electrode 2; Centre in bending 4 is provided with hollow out 12.
Be provided with the cup-shaped moulding plastic jacket 6 of nylon material in the outside of shell 5, play the non-conductive effect; The outside at plastic jacket 6 and ring electrode 2 also is provided with the plastic injection-moulded body 1 that nylon material forms through mold injection,, and plays and insulate and the scantling of structure mating reaction the fixedly moulding of other part through it.
Safe automobile air bag electric igniter of the present invention is compared with the product on the market, has increased pencil 3, through the isolation of pencil 3; Make product when carrying out welded encapsulation, can not only adopt high relatively welding energy, guarantee firm welding between shell and the electrode holder; The light beam or the energy that have also guaranteed welding can effectively be isolated with the medicament that inside is adorned; Reduced medicament and be heated the probability of mistake blast takes place, the safety that improves production process, making has not only increased the production security of electric igniter product assembling; And add bending 4 setting; Guaranteed the relative stability of igniter 8 to a certain extent; It can stably be stored in the space; Its safety and validity have been guaranteed, have also played to product line construction to a certain extent and played the effect of economizing on the use of funds that a lot of safety measures can more be oversimplified.
