A method for assembling a cable connector which has an outer conductor part, and insulating part and an electrical cable that is prefabricated with an inner conductor part. In a first method step, the insulating part is introduced into the outer conductor part by relative movement between the insulating part and the outer conductor part. In a second method step, before or at least partially during the first method step, the electrical cable is prefabricated to have an inner conductor part secured on an inner conductor of the cable. In a third method step, during or after the first method step, the prefabricated cable is introduced into the insulating part up to a defined axial terminal position. The positions of the inner conductor part, the outer conductor part and/or the insulating part are fixed relative to each other by compressing the outer conductor part at least partly.

Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.

A crimping die including a first die piece having a recess portion and a second die piece having a protrusion portion is provided. An inner wall surface of the recess portion has a bottom wall surface and recess-side lateral end surfaces. An outer surface of the protrusion portion has a top end surface and protrusion-side lateral end surfaces. The bottom wall surface has a recess-side projection portion, a recess-side concave portion, and a recess-side curvature changing portion. The top end surface has a protrusion-side projection portion, a protrusion-side concave portion, and a protrusion-side curvature changing portion. A sign of curvature of the bottom wall surface changes at a boundary portion in the recess-side curvature changing portion with respect to the recess-side concave portion. A sign of curvature of the top end surface changes at a boundary portion in the protrusion-side curvature changing portion with respect to the protrusion-side concave portion.

A crimp ferrule includes an assembly portion assembled on a non-circular internal cross section of a multi-core cable and a diameter compensation portion forming a circular external cross section of the crimp ferrule on the multi-core cable. The assembly portion and the diameter compensation portion are arranged successively in an axial direction of the crimp ferrule.

An electronic device includes a fork structure having a pair of arms disposed in spaced relation and defining an open-ended channel therebetween. A surface of channel defines a seat opposite the open end. The channel has a width W.sub.1 at its narrowest section. A rigid wire of an electrical component is disposed in the channel generally adjacent to the seat. The wire has a width W.sub.2 that is greater than the width W.sub.1 so surfaces of the channel at the narrowest section defined by width W.sub.1 interfere with the wire, preventing the wire from moving towards the open end of the channel. The pair of arms are constructed and arranged to be moved toward each other so as to crimp the wire to the fork structure.

An assembly comprises a compression member configured to receive a force input from a compression tool and a frame including a cradle at one end, an end fitting at the other, and at least one structural member linking the cradle to the end fitting. The cradle is configured to engage one end of the connector and receives the prepared end of the coaxial cable. The end fitting is configured to detachably connect the frame to the compression tool and includes an aperture for receiving the force input from the compression tool. The structural member defines at least one surface configured to guide the compression member along the axis in response to the force input. The compression member imposes an axial force on the other end of the connector and is guided along the axis by the guide surface of the frame.

Systems and methods for evaluating a crimping application. A power tool includes a pair of jaws configured to crimp a workpiece, a piston cylinder configured to actuate at least one of the pair of jaws, and a pressure sensor configured to provide pressure signals associated with a crimping application. The power tool also includes an electronic processor connected to the pressure sensor. The electronic processor is configured to monitor, while performing the crimping application, a pressure applied by the piston cylinder, construct a pressure curve indicative of a change in the pressure applied during the crimping application, process the pressure curve into a vector indicative of one or more features, evaluate the crimping application based on the vector, and provide an output indicative of the evaluation.
