Abstract:     An improved electrical connector for use in pyrotechnic displays. The connector uses a single piece conductor pin, a clamp and a spring. Wires from a pyrotechnic projectile are attached to the connector by pushing down on the clamp and compressing the spring, providing an opening in which bare wire may be placed. Releasing the clamp causes the spring to extend, thereby securing the wire between the head of the conductor pin and the clamp by spring tension. After the projectile has been launched, a wire may simply be pulled out by the operator without pushing down on the clamp. The improved connector is especially useful where the pyrotechnic devices and associated electric circuitry are mounted on or near the water. Because of its primarily stainless steel structure, the connector is corrosion-resistant. It also provides a watertight seal, preventing the introduction of water to the firing control system circuitry. Individual components of the connector may be replaced as they wear out, obviating the need to discard the entire connector when one part wears out.

First Claim:
Show all 2 claims
I claim:     1. An apparatus for connecting the fuse of a pyrotechnic projectile to a firing control system, the apparatus comprising:
  • a one piece tube and flange having an upper end and an opposed flanged lower end;
  • a spring sized to fit over the upper end of the tube and flange;
  • a clamp having an upper side and a lower side and further having an opening adapted to fit over the upper end of the tube and flange;
  • a conductor pin having an upper end and an opposed lower end, said upper end having a head, said lower end sized to fit within said tube and flange; and
  • a groove in said head of said conductor pin, said groove sized to receive said upper end of said tube.
