Squib

Abstract

A squib includes a heat-generating portion that has an energizing portion and a fuel portion, and that is formed such that heat that is generated by supplying current to the energizing portion can be transmitted to the fuel portion to ignite same. The squib includes a noise removal device that is connected in parallel with the heat generating portion, and a circuit element that temporally scatters noise such that the noise is more completely removed by the noise removal device. In this manner, the heat-generating portion is protected from all typed of noise, including momentary noise, increasing reliability of the squib.

1 . A squib having a heat generating portion which includes an energizing portion and a fuel portion, said heat generating portion enabling heat generated by supplying current to the energizing portion to transmit to the fuel portion, comprising: 
 a noise removal device connected in parallel with the heat generating portion; and    a circuit element temporally scattering noise in the noise removal device.    
   
   
       2 . The squib according to  claim 1 , wherein the noise removal device is a two-way zener diode.  
   
   
       3 . The squib according to  claim 1 , wherein the circuit element is a capacitor.  
   
   
       4 . The squib according to  claim 2 , wherein the circuit element is a capacitor.  
   
   
       5 . A squib which can be ignited using a small amount of energy, comprising: 
 a heat-generating portion including an energization portion which is adapted to receive current from an electrical power source and a fuel portion which the energization portion ignites;    a noise removal device connected in parallel with the heat-generating portion; and    a circuit element operatively connected to the noise removal device and the heat-generating portion, and which temporally scatters noise.    
   
   
       6 . The squib according to  claim 5 , wherein the noise removal device is a two-way zener diode.  
   
   
       7 . The squib according to  claim 5 , wherein the circuit element is a capacitor.  
   
   
       8 . The squib according to  claim 5 , wherein the circuit element is a capacitor.  
   
   
       9 . The squib according to  claim 5 , wherein the noise removal device, the circuit element and the heat-generating portion are connected in parallel.  
   
   
       10 . The squib according to  claim 9 , wherein the noise removal device in disposed between the circuit element and the heat-generating portion.
