ABSTRACT:
A pistol-configured, solenoid driven wire cutting and seating tool is connectable by way of a standard power cord to an AC voltage source and is used to seat and cut a wire by squeezing a trigger that operates a solenoid control circuit. The tool has a pistol-shaped grip and a generally cylindrically shaped barrel having a main barrel body and a nose portion. The solenoid has a bore adjacent to a butt region of the barrel, coextensive with a longitudinal axis of the barrel and accommodating the translation of a solenoid plunger. A solenoid plunger extension hammer extends from an end of the solenoid plunger, so that the plunger extension hammer extends into a generally annular cavity of the solenoid bore. Surrounding the solenoid plunger extension hammer is a solenoid return compression spring. A wire seating and cutting tool holder is axially translatable within the nose portion of the barrel. The tool holder receives a shaft of a wire seating and cutting tool and has a neck surrounded by a tool holder return compression spring. The solenoid control circuit includes an energizing current supply switch coupled in circuit with a power supply and the solenoid winding, and a switch control circuit, which is responsive to the operation of the trigger mechanism to render the energizing current supply switch conductive for a prescribed period of time and thereby apply an associated duration of firing current to the solenoid winding.
