A connector crimping device includes a first movable block movable along a first direction and formed with a sliding slot extending along the first direction, a second movable block movable along the sliding slot, and an installation shaft rotatably installed to the first movable block and passing through the second movable block. The installation shaft includes a first shaft portion rotationally mated with the first movable block and having a first central axis extending along a second direction perpendicular to the first direction. The installation shaft has a second shaft portion rotationally mated with the second movable block and having a second central axis extending along the second direction. The second central axis is offset by a predetermined distance from the first central axis. A movement distance of the second movable block relative to the first movable block in the first direction is adjustable by rotating the installation shaft.

A cover stripping step of peeling off an insulating cover on a distal end side of an insulated wire to form a wire tip; a marking step of forming a marking on the insulating cover at a predetermined position; a first marking inspection step of inspecting a stripping state and the marking; a wire insertion step of inserting the wire tip into a closed-barrel-type pressure-bonding section; a pressure-bonding step of pressure-bonding the pressure-bonding section to be connected to the wire tip; and a second marking inspection step of inspecting a pressure-bonded state of the pressure-bonding section to the wire tip using the marking are performed in this order, and the first marking inspection step and the second marking inspection step are performed using the same inspection step part.

Measuring equipment for a crimp connection comprises a signal processing unit (150), a ranging sensor arrangement (100) based on using optical radiation, and a moving mechanism (102) that moves a formed crimp connection (104) and the ranging sensor arrangement (100) in relation to each other. The ranging sensor arrangement (100) measures the distance between the ranging sensor arrangement (100) and crimp connection (104) while the ranging sensor arrangement (100) and moving mechanism (102) are moved in relation to each other. The signal processing unit (150) generates surface profile data on the basis of the measured distances, uses the surface profile data of the crimp connection (104) to determine the quality of the crimp connection (104), and displays data related to the crimp connection (104).

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.

The subject matter herein includes a method for assembling a coaxial cable connector, a crimping tool for assembling a coaxial cable connector, and a coaxial cable connector. The subject matter includes crimping an inner ferrule onto an exposed braid of the coaxial cable, folding back an exposed braid of the coaxial cable over the inner ferrule, and crimping an outer contact onto the folded-back exposed braid, wherein the outer contact has distinct constrictions of reduced diameter in predetermined functional zones to reduce elongation of the outer contact and compression of the cable. This subject matter reduces the need for multiple terminal components, streamlines the assembly process, and ensures reliable mechanical and electrical connections for diverse applications.
