Electrically operated impact tool gun

An electrically operated wire seating tool, for seating a wire in a wire termination block, comprising a housing which includes an impact mechanism supporting barrel, and having a switch through which an operator causes a solenoid winding control circuit to output energizing current to a solenoid winding that is supported within a generally longitudinal passageway of said impact mechanism supporting barrel, said solenoid winding having an axial passageway therethrough, which is sized to accommodate the translation of a solenoid plunger along a longitudinal axis of said generally longitudinal passageway, generally longitudinal solenoid plunger extension hammer attached to said solenoid plunger, a wire seating tool holder supported within said generally longitudinal passageway such that it is struck by said solenoid plunger extension hammer by the energization of said solenoid winding in accordance with the operation of said solenoid winding control circuit, and being coupled to a wire seating tool, a first solenoid plunger return compression spring supported within said generally longitudinal passageway through said solenoid winding and normally urging said solenoid plunger away from said wire seating tool holder, said first solenoid plunger return compression spring being compressed by translation of said solenoid plunger in a direction that causes said solenoid plunger extension hammer to strike said wire seating tool holder, and a second, wire seating tool holder return compression spring supported within said generally longitudinal passageway and normally urging said wire seating tool holder toward said solenoid winding, said second, wire seating tool holder return compression spring being compressed by translation of said wire seating tool holder as a result of said solenoid plunger extension hammer striking said wire seating tool holder.

A pistol-configured, solenoid driven seating and cutting tool that is operative to seat and cut at least one wire in response to an operator holding the tool and squeezing a trigger, comprising a pistol-shaped grip that is contiguous with a generally cylindrically shaped main barrel body, which has a nose portion extending therefrom, said main barrel body containing a solenoid winding having a passageway therethrough that accommodates the translation of a solenoid plunger along a longitudinal axis of said barrel, a solenoid plunger extension hammer extending from said solenoid plunger, so that said solenoid plunger extension hammer extends into said solenoid passageway, a solenoid plunger return compression spring within said passageway through said solenoid winding and surrounding said solenoid plunger extension hammer, a wire seating and cutting tool holder axially translatable within said nose portion and being configured to receive a shaft of a wire seating and cutting tool, and having a neck surrounded by a tool holder return compression spring, and further including a solenoid control circuit having an energizing current supply switch coupled in circuit with a power supply and said solenoid winding, and a switch control circuit, which is responsive to the squeezing of said trigger to render said energizing current supply switch conductive for a prescribed period of time and thereby apply firing current to said solenoid winding, causing translation of said solenoid plunger and said solenoid plunger extension hammer so that said tool holder is struck by said solenoid plunger extension hammer, so as to seat and cut a wire.
