Embodiment Construction

[0031] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings.

[0032] Such as figure 1 In the first embodiment shown, a shielded electric cable 1 comprises two conductors 1a and 1a twisted together, inner insulating shells 1b and 1b made of resin and covering the outer surfaces of the conductors 1a and 1a respectively, covering the inner insulating shells 1b and a braided wire 1c on the outer surface of 1b (serving as a shield covering member), and an outer insulating case 1d covering the outer surface of the braided wire 1c.

[0033] The ground cable 2 includes a conductor 2a, and an outer insulating case 2b made of resin and covering the outer surface of the conductor 2a.

[0034] Such as figure 1 and 2As shown, the resin member pairs 3 and 3 have the same configuration, and each resin member 3 has a joint surface 3a. A generally arcuate shielded cable receiving groove 15 for receiving the shielded cable 1 an...

Abstract

In a shield-processing structure of a shielded cable 1, the shielded cable 1 and an earth cable 2 are held between two resin members 3 and 3, and ultrasonic vibration is applied to the resin members 3 and 3 while exerting a compressive force between the resin members 3 and 3, thereby forming a shield-processed portion. A shielded cable-receiving groove 15 and an earth cable-receiving groove 16 are formed in a joint surface 3a of each of the resin members 3 and 3, and earth cable-holding projections 17 are formed on each of the joint surfaces 3a, and is disposed adjacent to the shielded cable-receiving groove 15, and projects into the earth cable-receiving groove 16. Opposite end portions 17a and 17a of a distal end surface of each of the earth cable-holding projections 17 are higher than a central portion 17b thereof.

Description

technical field [0001] The present invention relates to a shielding treatment structure of a shielded cable formed by ultrasonically welding a shielded cable and a grounding cable using two resin members. Background technique [0002] Unexamined Japanese Patent Publication No. 2001-6767 discloses a conventional shielding treatment structure utilizing ultrasonic welding. This shielding processing structure utilizes respectively as Figure 7A The resin members 50 and 51 shown in 7B are formed. The resin members 50 and 51 are provided with arcuate-shaped cable receiving grooves 50b and 51b, the grooves 50b and 51b are respectively formed in the connection surfaces 50a and 51a of the resin members 50 and 51, the resin flow channel 50c is formed in the connection surface 50a, and A resin flow channel 51c is formed in the connection surface 51a. The resin member 50 has ground cable fixing bosses 50d (each boss has a flat distal end surface), each boss is formed between the shiel...
