Abstract: A crimp type F-Connector wherein the crimp required for easy installation reduced while affording reliable cable retention. A wide range of cable sizes are accommodated by one connector which is configured to provide adequate sealing and mechanical strength in the connector while facilitating optimized radial deformation for providing reliable retention and a reliable mechanical and electrical interface with the coaxial cable upon which it is crimped. The connector includes a crimping portion including a sleeve that has a plurality of ribs or external annular protrusions which are dimensioned to enhance rigidity and mechanical strength. The ribs are of equal diameters when uncrimped and are "flat" crimped to maximize the cable area against which crimp forces are applied. An innermost rib is proximate to a support wall and separated by an exaggerated spacing to reduce crimp forces experienced when installing the connector onto the cable.

Abstract: A method, installation tool, termination fittings, and test apparatus, for mass-production retrofit of aluminum wiring systems installed in buildings from 1965 to 1973, when aluminum was approved by many inspection departments. The re-termination fittings are customized for mass production on the basis of the sizes (10, 12, etc.) of the existing wire, the required movement of which with this method is minimal, an important factor in view of its frangibility. The battery-operated portable tool solidly swages the fittings to one, two, or more wires. Connection is made to duplex receptacles, the most frequently encountered device, by copper stubs which engage with both screws of the same polarity, assuring that the re-termination fittings are thus firmly fixed to the receptacle, and minimum wire movement will be required. With the re-termination fittings and the method of conductor arrangement, the electrician's work is easier and faster.

Abstract: An electrical connection of a terminal contact to an electrical conductor is crimped by applying compressive force to the right and left sides of the barrel of the contact but not at the center and not applying it directly toward the center, thus forming an "oblique" crimp. Such an oblique crimp can be formed using a punch die and an opposing anvil die each having a crimping surface with a central recessed relief area whereby the crimping surface does not compress the center of the contact barrel. On each side of the relief area is a substantial diagonal portion of the crimping surface, and outward therefrom is a transverse shoulder, both of which engage the contact barrel during crimping. This crimping is especially useful for contacts having closed or seamless barrel walls and also especially for crimping a slightly oversized barrel to a many-stranded conductor without an intermediate sleeve, and it is particularly useful where confined crimping is required.
