Problems solved by technology

However, when compared with the thickness T of the flat shielded electric wire 501, the wire diameter D becomes large
Therefore, the shielded electric wire suffers from the problem that the routing of the electric wire is restricted depending on the structure of the object on which the electric wire is installed, such as the structure of a vehicle

Embodiment Construction

[0023] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0024] Such as figure 1 As shown, the flat shielded electric wire 11 of the first embodiment of the present invention is such a shielded electric wire: the shielded electric wire includes a plurality of sheathed core wires 17, and the core centers 25 of the multiple sheathed core wires 17 are on the same horizontal plane Arranged side by side. The flat shielded electric wire 11 has an electromagnetic shielding structure consisting of a pair of long sides 13 facing each other, and another different electromagnetic shielding structure consisting of a pair of short sides 15 facing each other, the pair of long sides 13 being positioned with the The directions in which the plurality of sheathed core wires 17 are arranged in the wire section are consistent. Each long side 13 is configured to exhibit a higher shielding effect than that produced by the short sides 15 .

Abstract

A shielded electric wire that assumes a horizontally long cross sectional wire profile and includes a flat shielded electric wire that has a plurality of sheathed core wires whose core centers are positioned side by side at grade. The shielded electric wire has an electromagnetic shield layer that encloses all of the positioned sheathed core wires, and a pair of additional electromagnetic shield layers laid solely along a pair of mutually-opposed long sides in line with a direction in which the sheathed core wires are arranged in a wire cross section.

Description

technical field [0001] The present invention relates to a shielded electric wire exhibiting a laterally long and flat cross-sectional line profile, such as an elliptical (including ellipsoid) cross-sectional profile and a rectangular cross-sectional profile. Background technique [0002] In transmitting a plurality of signals, such as transmitting a video signal and transmitting a motor drive signal, shielded electric wires that collectively provide electromagnetic shielding to multi-core electric wires have now been widely used. For example, cables used to drive three-phase motors transmit high-voltage power and high-current power. Therefore, in consideration of electromagnetic interference with the environment, the cable employs a three-core shielded wire with heavy electromagnetic shielding (an electromagnetic shielding structure exhibiting high shielding performance). In a three-phase motor, the three connector terminals are usually arranged in a straight line. For thi...
