An electronic apparatus includes a substrate and an optical connector connected to a waveguide on the substrate. The optical connector includes a ferrule that holds an optical fiber and has front and rear parts along a connecting direction of the optical connector with respect to the substrate. The ferrule has a hook and a presser member provided on a bottom face at the front part of the ferrule, a projection provided on the bottom face at the rear part of the ferrule, and a sloping part including a groove formed in the bottom face to hold the optical fiber. The optical fiber is held obliquely downward toward the substrate by the sloping part. The substrate has holes to receive the hook and the projection, and a groove to receive the optical fiber.

A wire connector having a collar surrounding a set of wire ports in a wire connector with the collar providing a collective shield between an environment external to the collar the collar but not between the set of wires within the collar.

High speed connector inserts and cables having improved heat conduction, high strength, and may be manufactured in a reliable manner. One example may provide a connector insert having several paths by which heat may be removed from circuitry in the cable insert. In one example, heat may be removed from one or more circuits by forming a thermal path between a circuit and a shield of the connector insert. Another path may include one or more pads on a side of an integrated circuit board that are soldered directly to the shield. A braiding surrounding a cable may be soldered or otherwise thermally connected to the shield. Another example may provide a cable having a braiding that includes one or more types of fibers, such as aramid fibers. Another example may provide for increased manufacturability by using a wire comb and a solder bar.

A die extended in the service life. An anvil includes a base portion and a protruding portion, and further, includes a wall portion that is connected to rear surfaces of the base portion and the protruding portion. The wall portion extends further upward than the base portion, and extends further leftward and rightward than the protruding portion. Therefore, the rigidity of the protruding portion in a left-right direction is high.

A jumper cable having an end prepared for connecting to a coupling assembly. The prepared end includes an inner conductor, an outer conductor having a helical outer surface contour, and a dielectric core disposed between the inner and outer conductors. A weld washer: (i) threadably engages the helical outer surface contour of the outer conductor, (iii) receives a deformed edge of the outer conductor through an opening in the washer, and (iv) is penetration welded to deformed edge of the outer conductor. Operationally, the face of the weld washer augments the flow of electrical current to electrically ground the outer conductor to the coaxial cable connector.

An optical connector includes at least one optical fiber, and a ferrule configured to hold the optical fiber. In the optical connector, the ferrule has a hook and a presser member on a front part of a bottom face of the ferrule, and a projection on a rear part of the bottom face of the ferrule, in a connecting direction, and the optical fiber is held obliquely downward from a rear end of the ferrule toward the presser member of the ferrule.

A method is provided for electrically conductively connecting a contact part on the basis of copper to an electrical conductor composed of a plurality of individual wires containing aluminum. A cup-shaped contact part which has a bottom and a cylindrical sleeve, which is integrally connected to the bottom and protrudes from the bottom, is pushed with tight contact of the sleeve against the conductor to such an extent until the end face of the conductor rests against the bottom of the contact part. Consequently, at least one rotating tool (6) is applied with sustained pressure, until due to increased temperature of the conductor, the conductor is softened to such an extent that it integrally connects with the contact part. The wall of the contact part is not broken through by the tool. Finally, the tool is removed from the contact part.

A wiring harness assembly is presented. The wiring harness assembly is formed by a method that includes the steps of crimping an electrical wire cable within a crimping feature of an electrical terminal having wire strands protruding from the crimping feature and fusing the wire strands of protruding portion, or wire brush so that the wire strands are in intimate contact, thereby eliminating voids between individual wire strands of the wire brush. The wires may be fused by laser welding, soldering, or brazing. The method may be especially beneficial for wire strands having an insulative oxide layer, such as aluminum. The bonding reduces the resistance between the wire strands due to insulating oxide layers on the surface of the wire strands and inhibiting of corrosion by eliminating inter-strand gaps where electrolytes in solution may enter and cause galvanic corrosion.

A process and apparatus for collecting data for nondestructive evaluation of the quality of a crimped wire connector are provided. The process involves providing a crimping tool having an anvil and opposing jaw for crimping a terminal onto a stranded wire, moving the jaw relative to the anvil to close the distance between the jaw and the anvil and thereby compress the terminal against the wire, while transmitting ultrasonic waves that are propagated through the terminal wire combination and received at a receiving ultrasonic transducer as the jaw is moved relative to the anvil, and detecting and recording the position of the jaw relative to the anvil as a function of time and detecting and recording the amplitude of the ultrasonic wave that is received at the receiving ultrasonic transducer as a function of time as the jaw is moved relative to the anvil.
