At least one end part of the wire barrel (16) in an extension direction of the wire (11) is provided with an enlarged diameter portion (20) enlarged in diameter toward the one end part. At least one recess (24E) is provided at a position corresponding to the enlarged diameter portion (20) and in a region configured to come into contact with the core (13) in a placing surface (23) of the wire barrel (16) where the core (13) is arranged.

The invention relates to a manually operated pliers tool , which may especially be crimping pliers. According to the invention, the pliers tool is equipped with an electronics construction unit. The electronics construction unit is realized separately from a mechanical pliers part and arranged in a pliers head part of the mechanical pliers part, which is arranged between hand levers and pliers jaws. The electronics construction unit is attached to this pliers head part. The electronics construction unit extends at least on two opposite sides of the pliers head part, sandwiching the pliers head part, and comprises a connector, where the connector extends through or around the pliers head part between the two opposite sides of the pliers head part.

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 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 of the positioner, and the transmitter is configured to transmit the positioner data and the tool data to the computer.

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 monitoring system includes a sensor configured for electrical connection with at least one of a first element and a second element, and a crimping device including a first crimping fixture and a second crimping fixture. The crimping device may be configured to crimp said first element and said second element together. The sensor may be configured to monitor an electrical characteristic of at least one of said first element and said second element during crimping of said first element and said second element together. The first element may include an electrical terminal and the second element may include a conductor.

A 4-way indent tool includes a cover holding a motor and a drive screw operably coupled to the motor and an indenter holder holding four indenters positioned orthogonally around a terminal opening configured to receive a terminal. The 4-way indent tool includes a indenter actuator cam arm positioned adjacent the indenter holder to operably engage the indenters having cam surfaces engaging the corresponding indenters to actuate the indenters. The 4-way indent tool includes a drive nut threadably coupled to the drive screw being moved linearly on the drive screw between an unactuated position and an actuated position. The indenter actuator cam arm is coupled to the drive nut and moves with the drive nut between the unactuated position and the actuated position to actuate the indenters.
