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, safety during welding just becomes the important control point of production, and production facilities need invest considerable capital to transform.
The utility model content
The purpose of this utility model is to provide a kind of light beam of welding or energy of having guaranteed effectively to isolate with the inner medicament of being adorned, and has reduced medicament and has been heated and the probability of mistake blast takes place, the safe automobile air bag electric igniter of the safety of raising production process.
The utility model safe automobile air bag electric igniter comprises: ring electrode; Insulating glass is arranged between the described ring electrode; Single electrode is divided into first single electrode and second single electrode, and described first a unipolar end is connected with described ring electrode; Described second single electrode inserts in the described insulating glass; The bridge silk links together described ring electrode and described second single electrode by it; Shell is connected with described ring electrode, and described shell and described ring electrode and described insulating glass form a space; Igniter is arranged in the described space; Plastic jacket is arranged on the outside of described shell; Plastic injection-moulded body is arranged on the outside of described plastic jacket and described ring electrode; Be provided with pencil in described space, described pencil is connected with the side of described ring electrode away from the axle center.
The end away from ring electrode at described pencil is provided with the bending of pointing to the axle center; Centre in described bending is set to hollow out; Described pencil and described shell are fixed on the described ring electrode by the mode of laser welding; One end of described shell is provided with weak groove; Described shell is the cup-shaped stainless steel structure; Described plastic jacket and described plastic injection-moulded body are nylon material; Described plastic injection-moulded body forms by mold injection; Described plastic jacket is the cup-shaped moulding; The material of described bridge silk is Q alloy or platinum tungsten.
The utility model safe automobile air bag electric igniter is to increase a pencil in the structure of product newly, isolation by 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.
