    Abstract: The present invention provides a connector having a seamless tubular metallic shell which not only provides proper RFI/EMC shielding but also is constructed in such a way as to prevent ingress of moulding material into the spaces between contacts of the connector. This is achieved by forming one end of a seamless tube of ferromagnetic material (which is initially of substantially uniform cross-sectional area) such that is collapsed on to itself and a cable connected to the connector whereby to tightly seal the send of the tube on to the cable to prevent ingress of moulding material subsequently applied to the exterior of the shell. In the case of a cable providing a braid or foil shielding element, this process simultaneously provides an electrical bond between the shell and a portion of the shielding element of the cable exposed by removing a portion of the outer insulation covering of the cable.

    Abstract: A system for protecting exposed portions of an electric cable mounted in an electrical connector from detrimental components, such as liquids and gases, by inserting a movable sealing material into a cavity in the electrical connector and displacing the movable sealing material during the insertion of the electrical cable into the electrical connector so as to form an effective seal between the outer surface of the electrical cable and the inner surface of the electrical connector to prevent any detrimental components from entering into the electrical connector and attaching a continuous glob of movable sealing material to close an opening in the electrical connector so that, when an electrical cable is mounted in the electrical connector with the bared end portion passing through the glob of movable sealing material, exposed portions of the electrical cable will be protected by the movable sealing material.

  • Patent number: 4737124
    Abstract: A connector plug includes a plurality of contact pins carried by an insulating body which is installed in a cylindrical metal cover. The cylindrical metal cover has a semi-cylindrical rear portion which is engaged with a semi-cylindrical metal cover piece into a cylindrical form. A separtately molded insulating cap is assembled onto the cylindrical metal cover. Within the insulating cap, a cable clamp member having a thickness greater than that of the cylindrical metal cover is secured to a rear end extension of the cover. A cable connected to the contact pins is clampedly held by the cable clamp member.

  • Patent number: 4733464
    Abstract: The present invention provides a connector for terminating and connecting a portion of a cable. The connector is used with a cable having a core comprising synthetic filaments, a polymeric sheath covering the core, an inner sheath comprising braided metallic filaments covering the polymeric sheath, and a polymeric outer jacket covering the inner sheath. Portions of the jacket and the inner sheath are stripped proximate the portion of a cable to be terminated to provide an exposed polymeric sheath and core portion of a first predetermined length and an exposed inner sheath portion of a second predetermined length. A generally tubular outer sleeve, having an axial length at least slightly greater than the length of exposed braided metallic filaments, is positioned so that either sleeve end extends beyond the exposed portion of the braided metallic sheath.

  • Patent number: 4696532
    Abstract: An apparatus for terminating a coaxial cable includes a connection pin and a spring sleeve having first and second spring portions, the first spring portion receiving one end of the connection pin and the second spring portion receiving an end of a center conductor of the coaxial cable. The second spring portion has a conical outer surface received within a conical hole of a sleeve held in place by first and second connector bodies, the sleeve increasing a clamping force of the second spring portion on the center conductor when the center conductor is subjected to pull-out load.

  • Patent number: 4690481
    Abstract: A coaxial connector is described which has an improved plug pin and shell construction wherein the conventional machined pins and shells are replaced with stamped and drawn members providing for simpler manufacture, improved electrical and spring retention characteristics, and improved and simplified wire connections. In particular, the plug pin is hollow and is fixedly mounted in the plug shell, and the conductor is attached to the pin by a front end crimping of the hollow pin after the conductor is slipped into the pin.
