Embodiment Construction

[0067] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0068]As shown in FIG. 1, the shielded electric wire 1 is constituted by two core wires 1a and 1a twisted, insulating inner sheaths 1b and 1b respectively covering the peripheral portions of the core wires 1a and 1a by resin, As shielding members, a braided wire 1c for covering the outer peripheral portions of the insulating inner sheaths 1b and 1b, and an insulating outer sheath 1d formed of a resin material covering the outer peripheral portion of the braided wire 1c.

[0069] The ground wire 2 is constituted by the core wire 2a and an insulating outer sheath 2b formed of a resin material and covering the periphery of the core wire 2a.

[0070] As shown in FIGS. 1-7, a pair of resin parts 3 and 3 are the same member, and joint faces 3a and 3a are provided with wire abutment faces 16 on which shielded wires 1 and ground wires 2 are respectively abutted....

Abstract

In a shielding structure of a shielding electric wire in which the shielding electric wire and a ground wire are interposed between two resin members, and a compressive force is caused to act on the resin members and an ultrasonic wave is simultaneously applied to fuse the resin portions, thereby forming a shielded portion, a protruded portion 20 is provided on one of junction faces of the two resin members and a hole 21 including a protrusion inserting portion 21a for inserting the protruded portion 20 and a resin inflow portion 21b provided in an inner position from the protrusion inserting portion 21a and having a smaller width than a width of the protrusion inserting portion 21a is provided on the other junction face, and step faces at both sides on a boundary between the protrusion inserting portion 21a and the resin inflow portion 21b in the hole 21 are formed to be a pair of inclined faces 21c and 21c.

Description

technical field [0001] The present invention relates to a shield structure of a shielded electric wire formed by ultrasonically welding a shielded electric wire and a ground wire by means of two resin members. Background technique [0002] A conventional shield structure using ultrasonic welding has been disclosed in Unexamined Japanese Laid-Open No. 2001-6767. The shielding structure is formed by using two resin parts 50 and 51 having arcuate passages 50b and 51b and ultrasonic horns (horn) formed on common joint surfaces 50a and 51a, as shown in Fig. 13(a) and 13(b). More specifically, such as Figure 14-17 As shown, the ground wire 53 is installed at the upper position of the shielded electric wire 52, with the periphery of the core wire 52a covered with a braided wire (shield member) 52c and the mounting ground wire 53 inserted between the two resin parts 50 and 51. The electric wire 52 part is shielded so as to provide ultrasonic vibration through the ultrasonic horn ...
