Abstract
The present invention provides a non-electric initiator tip for use with a non-electric shock tube initiation device. The initiator tip of the present invention comprises an inner electrode, an outer electrode, and a conductive component electrically coupled to the inner and outer electrodes for applying current to the inner and outer electrodes to thereby cause a percussion spark to be generated. When the initiator tip is connected to an initiation device, the conductive component of the initiator tip is electrically coupled to electronics in the initiation device such that, when the initiation device is actuated, the electronics in the initiation device in conjunction with a power supply cause a voltage differential to be generated between the inner and outer electrodes and a percussion spark to be produced. The percussion spark initiates gun powder contained in a shock tube mounted to the initiator tip. In accordance with one embodiment of the present invention, the initiator tip comprises an inner electrode made of a material having a high melting point, such as, for example, steel/nickel alloys (e.g., stainless steel SS-304, SS-306), chromium/molybdenum alloys, Tungsten, etc. In accordance with another embodiment of the present invention, the initiator tip is encased in an insulative material to eliminate any possibility of electric shock to a person handling the initiation device.
