Description

The present invention relates to an electric wire fixing member, a wire harness, and a wiring structure of the wire harness.

Conventionally, a wire harness has been used as a bundle of electric wires connecting an electric unit and a communication unit inside a vehicle such as an automobile. A wire harness is used to supply power, ground, and communicate in the vehicle. In recent years, the electrification of vehicles (hybrid vehicles, electric vehicles, etc.) and the multifunctional / advanced functions (autonomous driving systems, connected cars, etc.) are rapidly advancing. Along with this, the wire harness has become bloated and it has become difficult to secure the wiring route thereof, and an efficient fixing / wiring means for the wire harness is required.

Therefore, flat electric wires have come to be used for the purpose of reducing the height of the electric wires. FIG. 1 is a diagram showing an example of a flat electric wire, FIG. 1A is a perspective view, and FIG. 1B is a cross-sectional view perpendicular to the longitudinal direction of the electric wire. As shown in FIG. 1, the flat electric wire 1 has a stranded wire conductor 3 made of a strand 2 and an insulating coating layer 4 that covers the outer surface of the stranded wire conductor 3. By having such a flat cross-sectional shape, the flat electric wire 1 has a low profile and is less likely to be broken, and is easily arranged along the floor panel of the vehicle.

A wire harness having a flat electric wire is usually integrated by sandwiching it with a clip composed of an upper case and a lower case, and is fixed in the vehicle. However, in this case, since each electric wire constituting the wire harness is only in surface contact with the upper case and the lower case, if an external force is applied in the width direction of the electric wire when arranging the wire harness, each electric wire becomes wide. In some cases, the wires may overlap each other or the wires may be twisted due to the deviation in the direction.

Therefore, studies have been conducted to prevent the electric wire from being displaced in the width direction in the clip. In Patent Document 1 (Japanese Unexamined Patent Publication No. 11-122759), a flat cable is sandwiched and held between a bottom and a cover, and a row of protrusions is provided in the width direction of the flat cable on the surface of the bottom and the cover in contact with the flat cable. Disclose a clip for a flat cable. The flat cable clip of Patent Document 1 stably holds the flat cable in the width direction by preventing the flat cable from shifting. Further, in Patent Document 2 (Japanese Unexamined Patent Publication No. 2012-235666), peaks and valleys continuous in the circumferential direction with a predetermined length are alternately provided in the axial direction, and a wire harness to be inserted is provided on the inner surface. Disclosed is a flat corrugated tube in which convex portions arranged between adjacent flat electric wires are continuously provided in the axial direction. The corrugated tube of Patent Document 2 has the above configuration to prevent the flat electric wires from overlapping each other.

In recent years, the number of various units such as electric units and communication units installed inside vehicles such as automobiles has increased, and the wiring routes of wire harnesses connecting these units have become more complicated. Therefore, as a method for fixing a wire harness having a flat electric wire, a method having a higher degree of freedom in the wiring route has been required. However, in the conventional clip, since the anchor exists only on the widest surface (or the surface along the arrangement direction of the electric wires) of the outer peripheral surface, the fixing position and fixing direction of the wire harness are limited. rice field. For this reason, the wiring route of the wire harness is also restricted, and it is difficult to design a flexible wiring route.

The present invention has been completed as a result of intensive research to solve the above problems. That is, in the present invention, the fixing position of the wire harness can be freely set by arranging the anchor mounting portion on a surface other than the surface having the largest area among the outer peripheral surfaces of the closed wire fixing member or inside the wire fixing member.

The electric wire fixing member of the present invention is an electric wire fixing member for collectively fixing a plurality of electric wires including a flat electric wire. The electric wire fixing member has a first member and a second member that can be fixed so as to sandwich a plurality of electric wires, and an anchor mounting portion. Here, "sandwiching a plurality of electric wires" means that the first member and the second member sandwich the plurality of electric wires, and at least one of the first member and the second member is at least one. It means fixing the electric wire by pressing the electric wire of the book. The anchor mounting portion intersects the outermost surface of the electric wire fixing member with the smallest area and the outer peripheral surface of the electric wire fixing member in the arrangement direction of the electric wires when the first member and the second member are fitted. It exists at a position that satisfies any one of the conditions of the surface and the inside of the electric wire fixing member. The area of each surface constituting the outer peripheral surface of the electric wire fixing member means the projected area of each surface without considering unevenness, and the "smallest surface" means each of the outer peripheral surfaces of the electric wire fixing member. It means the surface with the smallest projected area. There can be one or more faces with the smallest area. The "plane intersecting the arrangement direction of the electric wires" means a surface different from the surface along the arrangement direction of the electric wires (the surface on which the anchor is provided in the above background technique). There can be one or more surfaces that intersect the arrangement direction of the wires. The anchor mounting portion is a portion where an anchor can be mounted, and a clip through which a plurality of electric wires are inserted via the anchor can be fixed inside a vehicle such as an automobile. The anchor mounting portion of the electric wire fixing member of the present invention can be any of the smallest area of the outer peripheral surface of the electric wire fixing member, the outer peripheral surface of the electric wire fixing member that intersects the arrangement direction of the electric wires, and the inside of the electric wire fixing member. It exists in a position that satisfies one of the conditions. Therefore, the degree of freedom in the fixing position of the clip in the vehicle is high, the degree of freedom in the fixing direction of the wire harness can be increased, and the degree of freedom in the wiring path of the wire harness can be improved. In addition, the types of clips and anchors can be minimized to make effective use of resources.

The plurality of electric wires collectively fixed by the electric wire fixing member of the present invention include at least one flat electric wire. Examples of the flat electric wire include those shown in FIG. Typically, the plurality of wires has one or more flat wires and one or more round wires. Examples of the electric wire include a power supply line, a communication line, and a ground line. Further, a power supply line and a ground wire can be used as the flat electric wire. As the power supply line, a 12V system or 48V system power supply line can be used. A communication line can be used as the round electric wire, and an optical fiber cable or the like can be mentioned as the communication line. The plurality of electric wires may be two or more in total, and may be, for example, two flat electric wires and one round electric wire. Further, the plurality of electric wires may be four or more in total.

The first member and the second member are not particularly limited as long as they can surround the outer periphery of the plurality of electric wires in a fitted state and sandwich and fix the plurality of electric wires. The structure for fitting the first member and the second member is not particularly limited. In one example, one end of the first member and the second member in the width direction can be connected and integrated by a hinge so that the first member and the second member can be opened and closed. In this case, a claw portion is provided at the other end portion in the width direction of one member, and a claw locking portion is provided at the other end portion in the width direction of the other member. By locking and fixing the claw portion with the claw locking portion, the first member and the second member can be fitted and closed. Further, in another example, the first member and the second member are separated from each other, and claws are provided at both ends of one of the first member and the second member in the width direction, and the other. Claw locking portions are provided at both ends of the member in the width direction. Then, by locking and fixing the claw portion with the claw locking portion, the first member and the second member can be fitted and closed.

Further, in the form of fixing the plurality of electric wires so as to be sandwiched between the first member and the second member, at least one electric wire is pressed by at least one of the first member and the second member. It is not particularly limited as long as it is in the form of fixing the electric wire with. For example, of the first member and the second member, one member may have an electric wire holding portion, and the other member may have an electric wire accommodating recess. The presence of the electric wire holding portion presses the electric wire in this way, and the pressed electric wire is accommodated in the electric wire accommodating recess to fix the electric wire and effectively prevent the electric wire from being displaced in the width direction and the longitudinal direction. can. The electric wire holding portion and the electric wire accommodating recess may exist so as to correspond to a part of the electric wires among the plurality of electric wires, or may exist so as to correspond to all the electric wires among the plurality of electric wires. For example, in general, if the communication line is pressed excessively, there is a concern that the communication performance may be adversely affected. It may be configured.

In one embodiment, the outer peripheral surface of the electric wire fixing member is composed of four surfaces in a state where the first member and the second member are fitted (closed state). In this case, the outer peripheral surface is composed of a first surface and a second surface having the smallest area facing each other, and a third surface and a fourth surface having a large area facing each other, and the first to fourth surfaces. The shape of a substantially rectangular parallelepiped is constructed from the surface. Further, in relation to the arrangement direction of the electric wires, the outer peripheral surfaces intersect the arrangement direction of the electric wires facing each other (for example, substantially orthogonal to the arrangement direction of the electric wires), the first surface and the second surface, and face each other. It is composed of a third surface and a fourth surface along the arrangement direction of the electric wires (for example, substantially parallel to the arrangement direction of the electric wires), and the first to fourth surfaces form a substantially rectangular shape. Further, the anchor mounting portion exists at least on the first surface (a surface having the smallest area among the outer peripheral surfaces or a specific surface that intersects the arrangement direction of the electric wires). In addition to the first surface, the anchor mounting portion may be present on one surface, two surfaces, or three surfaces of the second to fourth surfaces. That is, the anchor mounting portion can exist on one surface, two surfaces, three surfaces, or four surfaces in total among the first to fourth surfaces. If there are anchor mounting portions on two surfaces in total, one is present on the first surface or the second surface, and the other (is angled with the first surface or the second surface). ) It is preferable to be present on the third surface or the fourth surface from the viewpoint of increasing the degree of freedom in the fixing direction of the wire harness. In still another embodiment, there is an anchor mounting portion inside the wire fixing member in a state where the first member and the second member are fitted (closed state).

Anchors can be attached to the anchor attachment portions, and anchors can be attached according to the number of anchor attachment portions. The electric wire fixing member further has an anchor integrated with a band having a connecting structure for connecting the first member and the second member, and the anchor may be attached to the anchor mounting portion via the band. In this case, a band is inserted through the anchor mounting portion, and the anchor is mounted on the anchor mounting portion via the band.
