Abstract
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.
Claims22
A shielded wire, comprising:
- at least one shielded core wire, in which a first conductive core wire is covered with a first insulating sheath;
- a conductive foil, which covers the at least one shielded core wire;
- a second insulating sheath, which covers the conductive foil;
- and
- a branch wire, in which a second conductive core wire is covered with a third insulating sheath;
- wherein 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 shielded wire, comprising:
- at least one shielded core wire, in which a first conductive core wire is covered with a first insulating sheath;
- a conductive cover member, which covers the at least one shielded core wire;
- a second insulating sheath, which covers the conductive foil;
- and
- a branch wire, in which a second conductive core wire is covered with a third insulating sheath,
- wherein 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;
- and
- wherein a space between the conductive foil and the at least one shielded core wire is filled with an insulating material having a heat-resistant property.
The shielded wire as set forth in daim 7, further comprising a reinforcing member provided on an inner face of the conductive foil.
A method of branching a sheathed wire from a shielded wire, comprising the steps of;
- providing at least one shielded core wire, in which a first conductive core wire is covered with a first insulating sheath;
- covering the at least one shielded core wire with a conductive cover member;
- covering the conductive cover member with a second insulating sheath to constitute the shielded wire;
- providing the sheathed wire in which a second conductive core wire is covered with a third insulating sheath;
- providing a pair of resin members, in which a bonding face including a groove is formed in each resin member and at least one protrusion is formed on at least one of the bonding faces;
- sandwiching the shielded wire and the sheathed wire between the pair of resin members such that the grooves face with each other while accommodating the sheathed wire therein;
- applying ultrasonic vibration such that ultrasonic waves are concentrated to the protrusions to thermally use at least the protrusion so that the bonding faces of the resin members are integrated with each other, while thermally fusing a part of the second insulating sheath and a part of the third insulating sheath so that the conductive cover member and the second conductive core wire are electrically connected.
