Low voltage pyrotechnic igniter assembly

Abstract

The electric pyrotechnic igniter of the present invention comprises a controlled power source providing low-voltage electricity to one or more remotely located, replaceable ignition elements which are housed in compressive clips capable of holding the ignition elements into direct contact with firework fuses.

1 . An igniter assembly, comprising: 
 a low voltage power supply with associated control mechanism and housing for same,    a compression clip with electrical connectors and seat for an ignition element, and    a heat producing ignition element.    
   
   
       2 . The igniter assembly as claimed in  claim 1 , wherein the power supply housing is constructed to enclose the power supply, associated control mechanisms, a utility light and interconnecting conductors.  
   
   
       3 . The igniter assembly as claimed in  claim 1 , wherein insulated electrical conductors are routed from the power supply to an electrical connection device or devices exterior with respect to the power supply housing.  
   
   
       4 . The igniter assembly as claimed in  claim 1 , wherein the compression clip is constructed of non-flammable, non-conductive, rigid material.  
   
   
       5 . The igniter assembly as claimed in  claim 1 , wherein the body of the clip also incorporates a utility light and associated power supply and means to control the same.  
   
   
       6 . The igniter assembly as claimed in  claim 1 , wherein two electrical conductors, insulated with respect to each other, are attached to or otherwise mounted onto the body of the clip, said conductors initiating at mating electrical connections and terminating at a conductive seat.  
   
   
       7 . The igniter assembly as claimed in  claim 6 , wherein the conductive seat is located proximal to the clip's jaw, in the area of jaw compression, with said seat providing both positive and negative electrical connection points for the ignition element.  
   
   
       8 . The igniter assembly as claimed in  claim 7 , wherein the conductive seat provides a mating electrical connection with the igniter element, that element being held to the seat by mechanical, magnetic or adhesive means.  
   
   
       9 . The igniter assembly as claimed in  claim 4 , wherein a standoff, constructed of non-flammable material, is mounted on the compressive face of the clip's jaw, opposite to the conductive seat, as a mechanism for directing the compressive force of the clip away from, but adjacent to, the heating member of the ignition element.  
   
   
       10 . (canceled)  
   
   
       11 . (canceled)  
   
   
       12 . The igniter assembly as claimed in  claim 10 , wherein the heating member is embedded in the structural substrate such that the substrate itself becomes the contact point of ignition.  
   
   
       13 . (canceled)  
   
   
       14 . (canceled)
