An electrical connector consists of a connector housing (10) and at least one electrical contact element (1). The connector housing (10) and/or the electrical contact element (1) have a lead content of <0.1 weight percent. A method for manufacturing a contact element from a blank which has a lead content of <0.1 weight percent, uses the following method steps: Loading the blank into a manufacturing machine; producing a pin region or a socket region for electrically contacting another, opposite contact element; producing a fixing region for fixing the contact element in an insulating body; producing a crimp region for electrically connecting a conductor to the contact element or finishing the crimp region if the blank has already been previously prepared on a different machine; and removing the finished contact element from the manufacturing machine.

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.

A coaxial cable assembly includes a coaxial cable having a shield conductor surrounding a central conductor, a shield terminal in contact with an inner surface of the shield conductor, and a ferrule configured to secure the shield terminal to the coaxial cable. The ferrule defines first and second crimping wings. The first and second crimping wings each having an arcuate shape and are compressively connected to an outer surface of the shield conductor. A distal end of the first crimping wing overlies a distal end of the second crimping wing. A method for forming the coaxial cable assembly and a crimping tool for attaching the ferrule to the coaxial cable is also provided.

A method for producing an electrical connection between an electrical conductor, which includes a plurality of individual wires, and a contact element. The electrical conductor is arranged in a contact portion of the contact element, and the contact portion and the electrical conductor are subsequently pressed together so that the contact portion surrounds the electrical conductor. A a plurality of mutually spaced elongate welded connections between the contact portion and the electrical conductor are produced by laser irradiation of the contact portion, or by laser irradiation of the electrical conductor through an opening in the contact portion. The elongate welded connections extend in an irradiation direction from an irradiated region of the contact portion, or from an irradiated region of the electrical conductor, through an entire cross-section of the pressed electrical conductor to a region of the contact portion opposite to the irradiated region, such that the electrical conductor is connected to this area of the contact portion; and the irradiated regions are arranged in the form of a grid.

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a first terminal to one end of an electric wire, a step of crimping a second terminal to the other end of the electric wire with a tubular seal member, a first waterproofing step of providing, at the one end of the electric wire, an anticorrosion member that covers an element wire bundle of the electric wire, and a second waterproofing step of providing, at the other end of the electric wire, a sealing member so as to fill gaps between conductive element wires of the element wire bundle in a tubular insulating sheath. The second waterproofing step includes a step of applying a moisture curable resin to the element wire bundle, and a step of applying a curing accelerator that accelerates curing of the moisture curable resin to the element wire bundle.

A wire operating tool, a component for the wire operating tool, a wire cutting and dividing method, and a wire connecting method are provided. The wire operating tool includes a first wire gripping tool; a first rod member connected to the first wire gripping tool and configured to be expanded and contracted in accordance with relative movement of a moving portion with respect to a base portion; a second wire gripping tool; a second rod member connected to the second wire gripping tool; a connecting member that connects the moving portion of the first rod member and the second rod member to each other in a separable manner; and a load bearing member configured to bear a tensile load acting on the first wire gripping tool and the second wire gripping tool when the moving portion of the first rod member and the second rod are in a separate state.
