A dual lead waterproof connector for reliably connecting end-to-end pairs of wires as to connect blasting cap leads to an electrical source for detonation, in which a resilient metal "C" clip is disposed lengthwise in a longitudinally extending cavity in each of a pair of elongated dielectric connector bodies fixed together and extending side-by-side. The legs of each C-clip are inclined towards each other and terminate adjacent an inside surface of the connector cavity. An unstripped lead to be spliced is inserted through a centering hole in an end plug which is guided to deflect a respective leg to move past the end thereof. The unstripped lead is advanced to bottom the end in a crotch formed by the opposite leg to establish a secondary electrical connection upon pulling on the lead, the lead insulation is sliced through by the edges of a contact slot formed into the end of the C clip leg to reliably establish a low resistance electrical connection to the lead conductor strongly resistant to pull out of the inserted lead. A mass of dielectric silicone fills the interior of each body to insure a waterproof connection. Shunts are provided to insure that stray induced currents cannot be set up to detonate a blasting cap if the connector is connected to a blasting cap during shipment. |
