An electro-hydraulic pump for hydrodynamic compression tools which comprises a pump housing carrying an electric motor and a hydrodynamic group for pressurizing a hydraulic liquid, a control circuit for controlling the electric motor, a flexible pressure hose connected to the hydrodynamic group, and a work head of the tool to communicate the hydraulic liquid pressure to the work head. A flexible control cable connects the control circuit in the pump housing to a hand held remote control. The hand held remote control comprises an actuating button for starting the electric motor and a button for selecting an operation mode of the electro-hydraulic pump from a plurality of pre-set operation modes, as well as a multifunction display which shows the selected operation mode.

A hydrodynamic compression tool comprises an electrical motor, which can be powered by a control circuit, a hydraulic pump which can be actuated by the motor so as to increase the pressure of a hydraulic liquid acting on an actuating piston, two jaws, which can be mutually moved by the actuating piston between an open position and a closed position for carrying out the compression or the cut, an actuating button, which acts on a switch of the control circuit to actuate the motor, a return device which returns the jaws to the open position by a return of the hydraulic fluid from the actuating piston towards the hydraulic pump through a return valve, and a mechanism for delaying the opening of the return valve via the return device, so as to allow verification of the position of the jaws before the return of the jaws to the open position.

A crimping tool including a main body, a force-applying device, and at least two crimping jaws for crimping a crimping connection to a conductor. The at least two crimping jaws are moveable relative to the main body by the force-applying device, and a compensating device which allows adoption of at least three processing positions of the at least two crimping jaws depending on a position of the force-applying device relative to the compensating device. A force storage means is arranged on the main body and allows, in a processing position of the at least two crimping jaws, in particular in which substantially no force can be transmitted to the at least two crimping jaws by the force-applying device, a force-locking connection to be made between the crimping connection and the at least two crimping jaws by a movement of the at least two crimping jaws relative to the main body.

A crimping tool with a housing, a motor, a switch connected to the motor for activating the motor, a pump driven by the motor, a piston driven by the pump, an indenter operably connected to the piston, and a tool head connected to the housing, wherein a workpiece can be disposed between the tool head and the indenter. A current sensor is connected to the motor for sensing current flowing through the motor. A processor receives current data from the current sensor, the processor analyzing the current data to determine completion of a crimping operation and/or an error condition. A display connected to the processor can indicate completion of a crimping operation and/or an error condition.

A pressing tool performs a pressing operation for the press fitting of parts. One part can have different outer dimensions within a specified range. A tool part acts on the part, is a part of a pivoting jaw which has an action surface, and can be pivoted about a pivot axis from a starting position having a greatest opening width to a pressing position having a smaller opening width. A hydraulic piston movable in a hydraulic cylinder applies a piston force, depending on a hydraulic pressure in the hydraulic cylinder. A higher pressing force is in effect when a greater opening width of the pivoting jaw is provided and when the maximum piston force is reached. When any opening width that is smaller than the greater opening width is provided, a pressing force lower than the higher pressing force is in effect when the maximum piston force is reached.

The invention relates to a crimping pliers force sensor. The crimping pliers force sensor comprises a transfer body which is contacted by a die half and a supporting body. At least one piezoelectric film is arranged between the transfer body and the supporting body. The transfer body and the supporting body comprise protrusions and recesses. By the protrusions and recesses the transfer body is floatingly accommodated in the supporting body with the provision of a guidance in a transversal plane.

A method aligns a crimping cassette crimping tool in a cable processing apparatus having a tensioning device for applying tension to a mounting part relative to a crimping device attachment surface. The crimping cassette includes the crimping tool having cooperating stationary and movable tool parts for crimping and a holding device that attaches to the mounting part fixed to the stationary tool part and has a position allowing a spatially-limited adjustment movement of the stationary tool part. The method includes releasing the tensioning device; inserting the stationary tool part into a tensioning device area; moving the moveable tool part towards the stationary tool part slightly before it touches the stationary tool part; moving the moveable tool part towards the stationary tool part until a pressing force between the tool parts is reached or exceeded and an alignment occurs between the tool parts; and applying tension with the tensioning device.

A wire terminating apparatus and method which allows for determining the quality of a wire termination. The method includes terminating the wire, monitoring the thermal properties of the termination with one or more thermal sensors and comparing the monitored thermal properties to stored thermal properties to determine if the termination is defective. If the termination is defective, the termination is discarded. The apparatus includes a wire termination zone. A thermal sensor is mounted on the wire terminating apparatus proximate the wire termination zone. The thermal sensor monitors the thermal properties of the termination to determine if the termination is defective.

A crimping cassette for a crimping device of a cable processing apparatus includes a crimping tool having stationary and movable tool parts configured to act together in a crimping operation of the crimping device. The crimping cassette further includes a holding device having at least two claws for attaching to a mounting part in a mounting area of the claws, the mounting part being directly or indirectly fixed to the stationary tool part. The holding device has a locked closed position in which the claws are firmly clamped to the mounting part; an unlocked closed position in which the claws loosely grip the mounting part for allowing an adjustment movement of the stationary tool part within a spatially limited adjustment range; and an open position in which the claws release the mounting part such that the stationary tool part is separable from the holding device.

A crimp tool calibration system for crimping a prepared wire into a corresponding contact wire barrel includes a computer, a positioner having a memory chip storing positioner data, and a tool frame. The tool frame includes a head having a receiving port therethrough, and configured for the positioner to be removably engaged with the receiving port during a crimping operation. The tool frame also includes a plurality of crimping dies positioned around a periphery of the receiving port, an adjustment device to adjust a crimp depth, and a positioner interface coupled to the tool frame. The positioner interface includes a tool memory for storing tool data, a reader, and a transmitter, where the reader is configured to read the positioner data stored on the memory chip or the positioner, and the transmitter is configured to transmit the positioner data and the tool data to the computer.
