- 8. The powered crimping tool of claim 1, further comprising: means for activating said motor.
- 9. The powered crimping tool of claim 8, where said activating means must be engaged for a pre-set interval during which said plunger moves from a crimper head start position to an intermediate no return position and where, thereafter said plunger will move on to a crimper head stop position and then to said crimper head start position irrespective of said condition of said activating means.
- 10. The powered crimping tool of claim 2, where said motor includes a pulse disk on a motor powered shaft and where said tool includes a pulse sensor; where said motor powered shaft will rotate until said pulse sensor has detected a selected number of pulses from said pulse disk to move said piston from said crimper head start position to said crimper head stop position; and where said means for electronically adjusting at least one of said crimper head start, pause, and stop positions causes said selected number of pulses to be numerically changed.
- 11. The powered crimping tool of claim 2, where said means for electronically adjusting at least one of said crimper head start, pause, and stop positions includes at least means for electronically adjusting said start position and means for electronically adjusting said stop position; where said motor includes a pulse disk on a motor powered shaft and where said tool includes a pulse sensor; where said motor powered shaft will rotate until said pulse sensor has detected a selected number of pulses from said pulse disk to move said piston from said start to said stop position; where said means for electronically adjusting said stop position causes said selected number of pulses to be numerically changed; and where said means for electronically adjusting said start position causes said motor powered shaft to rotate until said pulse sensor has detected a pre-set number of pulses from said pulse disk.
- 12. The powered crimping tool of claim 11, said motor powered shaft being connected to a speed reduction system, said speed reduction system being connected to a plunger threaded drive shaft; said plunger having a threaded drive channel receiving said plunger threaded drive shaft, said plunger having a guide member toward an upper end; said housing containing an insert having a plunger channel receiving said plunger guide member; where, when said motor is operated to cause said powered shaft to rotate in a first direction, said plunger threaded drive shaft rotates to cause said plunger to move in a crimping direction without rotation as permitted by a cooperation between said plunger channel and said plunger guide member; and where, when said motor is operated to cause said powered shaft to rotate in a second direction opposite said first direction, said plunger threaded drive shaft rotates to cause said plunger to move away from said crimping direction without rotation as permitted by a cooperation between said plunger channel and said plunger guide member.
- 13. The powered crimping tool of claim 12, further comprising: means for activating said motor.
- 14. The powered crimping tool of claim 13, where said activating means must be engaged for a pre-set interval during which said plunger moves from said start position to an intermediate no return position and where, thereafter said plunger will move on to said stop position and then to said start position irrespective of said condition of said activating means.
- 15. The powered crimping tool of claim 14, where said housing includes a lower housing portion which will be held by a tool operator.
- 16. A powered crimping tool, comprising: a housing containing a motor therein, said housing having a trigger switch, at least one adjustment switch, and a reset switch;said housing containing a circuit board having a controller operably connected thereto, said trigger switch, said at least one adjustment switch, and said reset switch being operably connected to said controller; said motor includes a pulse disk on a motor powered shaft and where said tool includes a pulse sensor, said motor powered shaft being operably connected through a speed reduction system and a plunger lead screw to a plunger movable between a start position with a value of “x” counts and a stop position having a value of “y” counts, there being a pause position with a value of “z” counts, said pause position being intermediate of said start position and said stop position; where, by a first operation of said trigger switch and said motor thereby, said controller will cause said motor powered shaft to rotate until said pulse sensor has detected a first selected number of pulses with a value of “z−x” counts from said pulse disk to move said piston from said start to said pause position, unless a stall condition is detected, where, by a second operation of said trigger switch and said motor thereby, said controller will cause said motor powered shaft to rotate until said pulse sensor has detected a second selected number of pulses with a value of “y−z” counts from said pulse disk to move said piston from said pause to said stop position, unless said stall condition is detected, and when said second selected number of pulses has been detected or said stall condition is detected, said motor powered shaft will rotate to return said piston to said start position; a first crimper and a second crimper, at least one of said first crimper and said second crimper operably connected to said piston; said first and second crimpers being spaced a first distance when said plunger is at said start position, being spaced a second distance when said plunger is at said pause position, and spaced a third distance when said plunger is at said stop position, said first distance being greater than said second distance, said second distance being greater than said third distance; where, when said tool is in a reset mode, said at least one adjustment switch can be pressed to adjust said start position and said value of “x” counts; and, where, when said tool is in a crimp mode, said at least one adjustment switch can be pressed to adjust said stop position and said value of “y” counts.
