An electrical clamp connector with first and second half portions connected together and providing at least two mating grooves for electrical conductors to be electrically bridged. Bridging plates extend transverse to the grooves in one half portion and oppose corresponding bridging plates in the other half portion. Each bridging plate has first and second sets of piercing teeth to pierce the conductors at the grooves. The second half portion has substantially greater depth than the first half portion. Improved high real torque connecting means are provided by a bolt, a threaded upstanding tubular pipe in the second half portion, a first threaded cylindrical passage underlying the tubular pipe, a flat or curved metal plate with a threaded passage and encapsulated in the second half portion substantially above the bottom of the second half portion, and a second cylindrical passage below the metal plate. The threaded pipe, threaded first cylindrical passage, threaded plate passage, and second cylindrical passage are precisely aligned, and one continuous thread extends through the pipe, first passage and metal plate by means of drilling the passages in one continuous operation and tapping the passages in another continuous operation The plate lies within a range of distance below the bottom of the electrical bridging members to allow the metal plate to act as the primary load-bearing member, and to provide sufficient compression and displacement of the intervening material to maintain a loaded connection through bare wire cold flow and high temperature cycling. The bolt terminates within the connector half to avoid conductor and human injury. |
