  • Patent number: 7431608
    Abstract: A shielded cable connecting structure for connecting a shielded cable, the shielded cable including an electric wire portion which has a conductor and an inner sheath covering the conductor, a braided wire braided around the inner sheath, and an outer sheath covering the braided wire, the shielded cable connecting structure includes a connecting member. The connecting member includes a connecting main body, a press-fastening portion which press-fastens at least part of the shielded cable, a connecting portion which connects to the braided wire, and a spacer which connects to the braided wire. The spacer increases a contact pressure of the braided wire with the connecting portion.

  • Patent number: 7425161
    Abstract: An intermediate portion of an insulating sheath of a coaxial cable is removed, and a first insulating sheath portion is drawn toward a second insulating sheath portion, so that a braid is projected into an annular shape outwardly from an interval between opposed ends of the first and second insulating sheath portions to form an annular projecting braid portion, and this annular projecting braid portion is fixed so as to be connected to a portion (that is, a braid fixing portion) of a coaxial cable shielding terminal for connection to an end portion of the coaxial cable. This connecting and fixing operation is effected by press-contacting or press-clamping.

  • Patent number: 7121903
    Abstract: The terminal includes a front portion, a middle portion, and a rear portion. The rear portion is opened and has a pair of upright segments. The front portion is a shape of hollow cylinder and has bent tips. The middle portion is partly opened and an inner edge thereof has a collapsed or chamfered face. A step H is disposed between the rear portion and the front portion so that the middle portion is downwardly tapered to the rear portion. A through-hole is disposed at inner wall of the middle portion close to the rear portion for a part of the core wires, preferably edges of the covers also, to be visible through the through-hole.

  • Patent number: 7077712
    Abstract: The jointing sleeve component includes a sleeve made of electrically conductive metal. A diameter of the sleeve is to be reduced by swaging on a condition that core wire ends of a plurality of coated electric wires are received in the sleeve. Each core wire end is obtained by removing an insulating coating from the coated electric wire. The jointing sleeve component electrically connects the core wire ends to each other. The sleeve is formed in a pipe-shape from a developed material, which is stamped out from a plate made of the electrically conductive metal to have a specific shape.

  • Patent number: 7074077
    Abstract: A connection cap that includes a rear end wall positioned at a rear end of the connection cap for confining a sealing uncured resin, an opening positioned at a forward end of the connection cap for inserting a jointing portion of core wires of electrical cables, and a cylindrical wall extending from the opening to the rear end wall. The cylindrical wall has an inner surface formed with a plurality of ribs for positioning the jointing portion in the connection cap. The ribs are distributed in a circumferential direction to uniformly support the electrical cable. The uncured resin intrudes clearances each defined between adjacent two of the ribs. The inner surfaces of ribs define an inscribed circle having a diameter substantially the same as an outer diameter of a conductive sleeve for crimping the core wires. Advantageously, the ribs each have a forward end portion formed with a tapered surface gradually rising toward the rear end of connection cap.

  • Publication number: 20060121758
    Abstract: In a method of grounding a shielded wire and a structure of grounding a shielded wire, a ring portion is formed in a ring shape by leading a braided wire to or to an opposite side of an insulating outer sheath so as to be separated in an outer circumferential direction of the insulating outer sheath. With respect to an outer circumference of the insulating outer sheath, an inner circumferential cylinder is disposed at an inner circumference side of the ring portion and an outer circumferential cylinder is disposed at an outer circumference side thereof. Further, the outer circumferential cylinder and the inner circumferential cylinder are connected each other to form a sleeve fitting. With the sleeve fitting, an attached wire is connected to the ring portion, such that grounding is performed.
