摘要 |
An electrically actuable ignition assembly comprising an electric ignition element having insulated electrical leading wires connected by means of conducting metal contact elements to the ends of a secondary winding of insulated wire on a transformer ring core. The transformer core and contacts are preferably encased in a synthetic plastics case. The assembly is for use in blasting operations in which multi-shot rounds are fired from an a.c. supply by electromagnetic coupling of the supply with the secondary winding by means of a single primary wire threaded through the ring cores of a plurality of assemblies. The use of the metal contact elements eliminates the previously used soldered joints between the ignition element leading wires and the transformer secondary winding. |
