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.
Claims20
A compression apparatus comprising:
- a compression head;
- a hydraulic pump operably connected to the compression head;
- an electric motor operably connected to the hydraulic pump;
- a power source electrically connectable to the electric motor to drive the motor;
- a sensor connected to the power source for sensing voltage of the power source;
- and
- means for disabling operation of the motor, the means for disabling being connected to the sensor to disable operation of the motor when the sensor senses a predetermined inadequate low voltage level of the power source.
A hand-held crimping tool comprising:
- an electric drive motor;
- a battery for powering the electric motor;
- and
- means for disabling crimping ability of the tool connected between the battery and the electric drive motor by interrupting supply of power to the electric drive motor based upon the battery having a predetermined inadequate low voltage level.
A hand-held crimping tool comprising:
- a compression head;
- a drive system operably connected to the compression head, the drive system having a hydraulic pressure system with a pump, an electric motor connected to the pump, and a battery;
- and
- a control system operably connected to the motor, the control system having a user actuated activation trigger, a hydraulic system pressure switch, and means for disabling operation of the motor when the pressure switch is activated by a predetermined hydraulic pressure in the hydraulic pressure system.
