Abstract

A crimping tool for crimping electrical connectors. The tool has a compression head, a hydraulic pump, an electric motor, a removable rechargeable battery, and a control system. The control system has a printed circuit board that monitors voltage of the battery, a trigger, and a hydraulic system pressure sensor. The tool is prevented from starting a crimp operation if the circuitry on the printed circuit board senses a predetermined inadequate low voltage level of the battery that could otherwise prevent a good crimp from being obtained. After a good crimp is obtained, the circuitry disables operation of the motor for a predetermined amount of time.
