A plurality of shielded core wires has a first diameter. A conductive cover member covers the shielded core wires. A first insulating sheath covers the conductive cover member. A pair of resin members, each formed with a groove having a semi-ellipsoidal shape are thermally integrated with each other for forming an ellipsoidal through hole while accommodating the first insulating sheath therein. A major axis length of a cross section of the ellipsoidal through hole is substantially identical with a length obtained by adding each first diameter, twice a thickness of the conductive cover member and twice a thickness of the first insulating sheath. A minor axis length of a cross section of the ellipsoidal through hole is substantially identical with by adding the first diameter, twice the thickness of the conductive cover member and twice the thickness of the first insulating sheath.

Two covered wires are conductively connected to each other by overlapping with each other at connection portions. The overlapped connection portions are pinched by a pair of resin chips. By melting cover portions and pressing resin chips from outside, the conductive wire portions of the covered wires are conductively contacted with each other at the connection portions. The pair of the resin chips are melt-fixed to each other to seal the connection portions. A crossing angle .theta. of the two covered wires at the connection portion is set to no less than 45.degree. and greater than 135.degree.. Thus, the covered wires can be conductively connected with each other inexpensively and easily. Further, a connecting state having an excellent electrical characteristic can be obtained stably.

In at least one shielded core wire, a first conductive core wire is covered with a first insulating sheath. A conductive foil covers the at least one shielded core wire. A second insulating sheath covers the conductive foil. In a branch wire, a second conductive core wire is covered with a third insulating sheath. A part of the second insulating sheath and a part of the third insulating sheath are thermally fused so that the conductive foil and the second conductive core wire are electrically connected.

A covered wire connection structure is formed by the steps of: pinching a covered wire with a pair of resin chips; pressing and exciting a cover portion of the wire by ultrasonic vibration so as to conductively connect conductive portions of both the covered wires at the connection portion; and melting a pair of the resin chips so as to seal the connection portion. The resin chip comprises main melting portions for pinching the connection portion which are melted to a mating resin chip so as to seal the connection portion, and auxiliary melting portions which are formed of material compatible with the cover portion of the covered wire introduced from the main melting portions and pinch the cover portion such that they are melted to the mating resin chip. The auxiliary melting portions and cover portion of the covered wire are melted together and integrated so as to seal an introductive portion of the covered wire from the resin chips. As a result, a reliability in connecting the covered wires by ultrasonic vibration is maintained and waterproofness in the connection portion is improved.

Two covered wires conductively connected with each other are overlapped with each other at connection portions. The overlapped connection portions are pinched by a pair of resin chips. Cover portions are melted and pressurized from the outside of resin chips capable of obtaining a sealing condition and providing an excellent melting operation efficiency so as to connect conductive wire portions conductively at the connection portions. Then, the pair of the resin chips are melted together to seal the connection portions. In introducing end portions in which a covered wire is introduced out of the resin chips, between a melting surface relative to a mating resin chip and an outer peripheral surface, a round corner having a curvature continuously changing smoothly is provided. Thus, it is possible to obtain a sealing condition securely and an excellent melting operation efficiency.

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.

A connecting structure for a shielded wire, including a shielded wire having a core made of a conductor, a core cover for covering the core, a braid provided around the core cover for shielding, and an insulating outer cover provided around the braid for covering the core, core cover and braid; and a shield terminal having a lead wire attached at an end to a terminal metal and conductively connected at a portion between the attached end and an unattached end to the braid of the shielded wire. This structure is formed by placing the portion of the lead wire of the shield terminal on the insulating outer cover of the shielded wire, placing a resin chip on the portion of the lead wire of the shield terminal, and applying an ultrasonic vibration so as to melt and disperse the insulating outer covers of the shielded wire and the lead wire, thereby forming a shielded conductive portion in which the shield terminal and braid are conductively in contact with each other.

With plural conductive wire materials wrapped by a connecting plate, the plural conductive materials being located between a first electrode and a second electrode of a power supply, the first electrode abutting on the conductive wire materials, the second electrode opposite to the first electrode abutting on said connecting plate, a voltage is applied between the first and the second electrode by the power supply so that the conductive wire materials are welded to the connecting plate. Thus, there is provided a method of connecting the conductive wire materials to the connecting plate which can prevent damages of the vicinity of a crimping portion due to heat and provide complete metallic coupling between the wire materials and the connecting plate with less electric power without using a third member such as metal having a low melting point.

A shielded cable includes core wires, an inner insulating cover for covering the core wires, a braided wire on an outer periphery of the inner insulating cover, and an outer insulating cover on an outer periphery of the braided wire. A shielded terminal has an insertion connecting portion coated with low-melting point joining material. The insertion connecting portion of the shielded terminal is inserted into the inside of the shielded cable from outside of the outer insulating cover such that the low-melting point joining material opposes the braided wire. With this condition, the shielded cable is subjected to ultrasonic vibration through a plurality of small protrusions of an ultrasonic horn over the outer insulating cover. As a result, the low-melting point joining material is melted so as to conductively connect the insertion connecting portion and braided wire to each other.

Two covered wires conductively connected are overlapped with each other at connection portions S. The overlapped connection portions are pinched by a pair of resin chips. Cover portions are melted and the conductive wire portions of both the covered wires are conductively contacted with each other at the connection portions by pressing from outside of the resin chips. Then, the pair of the resin chips are melt-fixed to each other to seal the connection portions. The resin chips are provided with first melting portions which are melt-fixed to a mating chip in area including the connection area to seal the connection portions and second melting portions which are separated from the first melting portions and melt-fixed to the mating chip in area other than the connection portion. Thus, it is possible to achieve reduction of conducting resistance and improvement of mechanical strength.
