Abstract: A spark ignition device, ground electrode therefor, and methods of construction thereof are provided. The spark ignition device includes a generally annular ceramic insulator with a metal shell surrounding at least a portion of the ceramic insulator. A center electrode is received at least in part in the ceramic insulator and a ground electrode extends from the shell to a free end portion. A firing tip is attached adjacent the free end portion of the ground electrode to provide a spark gap between the center electrode and the firing tip. The free end portion is at least partially bounded by at least one “as laser cut” peripheral side extending adjacent the firing tip.

Abstract: An electrical junction assembly for a wiring harness (10) couples one or more branch wires (18) to a main trunk line (12). The junction assembly includes a housing (16) having an internal cavity into which is received first (34) and second (36) trunk terminals which interlock with one another and establish electrical conductivity therethrough. A branch wire (18) is inserted into the housing (16) through a branch opening (28). The branch wire (18) has a branch terminal (48) on its end which is adapted to mechanically connect to the interlocked first (34) and second (36) trunk terminals, thereby establishing electrical conductivity between the branch wire (18) and the main trunk line (12). A mounting member (56) is formed integrally on the housing (16) to provide a secure connection to a suitable mounting structure (58). A hook (40) within the cavity in the housing (16) automatically engages and securely retains the second trunk terminal (36) when inserted into a full operative position. Cable seals (54) on each of the wires (18, 30, 32) seal against the respective openings (22, 24, 28) into the housing (16) to protect the electrical connections established therein.

Abstract: A spark ignition device includes a ceramic insulator with a metal shell surrounding at least a portion of the ceramic insulator. A ground electrode is attached to the shell. The ground electrode has a ground electrode sparking tip spaced from a central sparking tip by a spark gap. A first terminal is arranged in electrical communication with the central sparking tip and is configured for electrical connection with a power source. The device further includes a second terminal configured for electrical connection with the power source. The second terminal is spaced from the first terminal, with the second terminal being arranged in electrical communication with the first terminal. A heater element brings the first terminal in electrical communication with the second terminal and completes an electrical circuit. The heater element has a resistance greater than the first and second terminals thereby producing a significant source of heat.
