Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pin type squib for igniting an ignition charge in a gas generator used for an air bag of an automobile, and in particular, an automatic ignition for automatically igniting at a predetermined temperature (auto ignition). The present invention relates to a gunpowder loaded with a composition for use.

[0002]

2. Description of the Related Art Gas generators for air bags of automobiles, which have a housing made of a material that deteriorates at high temperature such as aluminum, should be protected from fire during storage / transportation of the gas generator or vehicle fire. As a measure against housing burst, an auto ignition function is incorporated.

This auto-ignition function is performed by incorporating an auto-ignition composition that automatically ignites at a predetermined temperature in an appropriate position of the housing of the gas generator. However, if a temperature-sensitive composition for automatic ignition is incorporated in the initial stage of the assembling process, the handling property in the subsequent process is deteriorated. Therefore, there has been proposed a squib that is normally installed last in a gas generator, in which a powder having an auto-ignition function is incorporated (see Japanese Patent Laid-Open No. 7-232613).

Further, as the squib, a pin type squib which can be connected by inserting a connector is used for convenience of wiring. This pin-type squib comprises a cup formed of a metal material and having a bottom portion, a gunpowder charged in the bottom portion of the cup, a plug that closes the cup, and two pins for energizing that are erected on the plug. An embolic assembly including a heating element that crosslinks between the two pins and ignites the explosive is mounted in a mold, and an insulating flange is formed around the pins by integral molding with resin. It is manufactured by forming (see Utility Model Registration No. 300573).

[0005]

However, in the pin-type squib incorporating the explosive having the auto-ignition function, the embolus assembly is heated during the integral molding with the resin and the self-igniting composition is automatically ignited. Since there is a possibility that the temperature will rise to a certain temperature, it becomes difficult to integrally mold the resin. Further, there is a problem in that the conventional pin-type squib mounting structure is complicated regardless of the presence or absence of an explosive having an auto ignition function.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a pin type squib having an auto ignition function and easy to assemble. There is a place to do it. Another object of the present invention is to provide a pin-type squib mounting structure that can be easily assembled regardless of the presence or absence of the auto ignition function.
