  • Patent number: 5667400
    Abstract: An obliquely disposed insulation displacement contact for the communication and data transfer. Wires having a lower rigidity than a copper wire of 0.4 mm diameter can also be contacted, and the insulation displacement contact to be provided is intended to fit into the previously used receiving portions of housings, without reducing the rigidity of the insulation displacement contact. This is achieved by opposingly providing angles, bending or parallely displacing contact parts towards outside the contact zones of the contact legs in the area of the contact slot or by cut-free portions of the contact zones.

  • Patent number: 5667395
    Abstract: A communication card and the structure of a jack therefor. The end face of the card is provided with a slit-like aperture. Into the aperture there is inserted a base plate having a thickness smaller than the width of the aperture so as to allow insertion into the interior of the card and removal from the card. The base plate is provided with a notch directed to the outside when viewed from the card. The notch passes through the base plate in the direction of its thickness. The jack is formed by utilizing this notch. The plug, on the other hand, is of a rectangular parellelpiped shape and is electrically coupled to a cord. The inner surface of the notch is configured so as to be able to receive the plug. When the plug is inserted, the notch receives and holds the plug. At that time, the notch receives and holds the plug in such a manner that the direction of the longest edge among the edges of the plug, or the extending direction of the cord is parallel to the major planes of the card.

  • Patent number: 5667404
    Abstract: The present invention provides a co-axial connector for a high frequency cable which includes a slit in the earth metal fittings. The slit enables the earth metal fittings to be widened and allows insertion of an insulating bushing into the earth metal fittings. After insertion, the slit returns to its home position by the spring tension of the earth metal fittings and retains the insulating bushing by spring tension. This configuration makes assembly easier. Furthermore, after the insertion of the insulating bushing into the earth metal fitting, a shielding cylinder is engaged with the earth metal fittings in order to cover the rear end of the earth metal fittings. This configuration prevents high-frequency signals from leaking, and does not require the widening of the slit, while connected to the other connectors, which loosens the engagement between the earth metal fittings and the insulating bushing.

  • Patent number: 5660565
    Abstract: The coaxial cable connector includes an inner conductor or "signal wire" connector in the form of a hollow needle, an outer conductor or "wire mesh" or "cable sheath" connector spaced radially from the signal wire connector, insulation spaced radially between the inner and outer conductor connectors, and an external protective sleeve spaced radially from the wire mesh or cable sheath connector. Both the inner conductor needle and the insulation have alignment lugs for ease of manufacture and assembly, and the external diameter of the needle shaped ends are tapered to facilitate a simple method for gripping and providing a seal against water, dirt and debris. The end of a cable is inserted into the coaxial cable connector, without stripping, with the cable signal wire being directed into the signal wire connector. As the coaxial cable is depressed into the protective sleeve, the needle-shaped inner conductor electrically contacts the coaxial cable signal wire.

  • Patent number: 5660568
    Abstract: A communications card provides an electronic interface between a host computer and a transmission media line. The communications card includes a releasable adaptor which interconnects an electrical connector of the transmission media line to the communications card when in use. In a first attachment position, which may be used as a storage position, the adaptor integrates into the overall configuration of the communication card to present a configuration that conforms with PCMCIA communication card architecture. For certain PCMCIA socket configurations, this integrated attachment position may also be used as an operational position. In a second attachment position, the adaptor forms an extension of the communications card, extending away from the computer socket to accommodate more restrictive socket configurations. The communications card also includes an optional connector terminal to permit connection to an electrical media line connector of a second type.

  • Patent number: 5658181
    Abstract: A die is disclosed for applying radial force to an eccentric workpiece. The die includes a set of faces that are each inclined from an orthogonal relationship with a different radial plane of the workpiece by an offset angle. The die also includes wedges that are positioned on the faces. They each have a jaw surface and a slide surface that are inclined from a parallel relationship with each other by a wedge angle that equals the offset angle of their respective face. The wedges can move over the faces to abut the workpiece along each of a plurality of transverse planes. In each of these planes, their movement can accommodate the workpiece's eccentricity in that plane. In addition, each jaw surface abuts the workpiece in a tangential relationship.
