An electric wire protection member 1 according to an embodiment of the present invention.
Reference numeral 0 denotes a long synthetic resin base portion 100 fixed to a floor or a wall surface, as shown in FIGS. 1 and 2, and provided on the upper side of the base portion 100 by being attached thereto. And a cover portion 200 made of synthetic resin. Wire protection member 1
0 is between the base part 100 and the cover part 200,
Cavity 15 for accommodating electric wires (not shown) such as signal lines
0 is formed. The electric wire protection member 10 is characterized in that an electromagnetic wave shielding means 300 is provided so as to surround an electric wire (not shown) housed in the cavity 150. Hereinafter, the structure of each member will be described in detail in the order of the cover part 200, the base part 100, and the electromagnetic wave shielding means 300.

The cover 200 comprises a top plate 210 having a substantially arc-shaped cross section, and a pair of ridges 220, 220 projecting symmetrically from both sides of the back surface of the top plate 210 to the back side.

The ridge 220 is formed continuously in the longitudinal direction of the cover 200. The base of the protruding ridge 220 is perpendicular to the back surface, and is formed in a substantially rectangular shape with a curved middle portion so that the front end is inclined outward with respect to the base. As a result, the base is inclined inward, and the tip is formed so as to face substantially directly below.

The base portion 100 has a flat bottom plate portion 110.
Having. The bottom plate 110 is slightly narrower in width than the cover 200 so as to be completely covered by the cover 200.
Two parallel rising portions 120 and 130 are protrudingly provided on both side surfaces of the bottom plate portion 110. Startup unit 12
0, 130, a concave groove 140 into which the ridge 220 fits.
Are formed. The concave groove 140 is formed in a substantially rectangular shape with an intermediate portion curved corresponding to the shape of the ridge 220.

The outer rising portion 120 is formed in a substantially rectangular shape with a curved middle portion corresponding to the outer shape of the concave groove 140.

The rising portion 120 contacts the back surface of the cover portion 200 in a state where both side edges of the cover portion 200 contact the mounting surface 400 of the base portion 100, and the cover portion 2
00 is formed. However, the leading end of the rising portion 120 and the cover 2 contacting the leading end are provided.
As described later, conductive materials 301 and 302 of the electromagnetic wave shielding means 300 are provided on the back surface of the sheet No. 00, respectively. In addition, the cover portion 200 that contacts the mounting surface 400
The conductive material 302 is also provided on the both side edges.

Therefore, the outer rising portion 120 contacts the back surface of the cover portion 200 in a state where both side edges of the cover portion 200 abut the mounting surface 400 of the base portion 100, and The state is a state in which the conductive materials 301 and 302 are interposed.

The inner rising portion 130 is provided with the bottom plate portion 110.
A vertical plate portion 130a extending substantially directly above the cover portion 20;
And a horizontal plate portion 130b extending inward from the upper end portion of the vertical plate portion 130a along the rear surface of the zero.

The vertical plate portion 130a is formed in a substantially rectangular shape with a curved middle portion corresponding to the shape inside the concave groove 140. Boundary part 1 between vertical plate portion 130a and horizontal plate portion 130b
30c is curved in a substantially arc shape.

The horizontal plate portion 130b is used to make the outer end of the upper surface of the rising portion 130 substantially arc-shaped,
The purpose of this is to regulate the movement of the electric wires (not shown) accommodated in 00 at the time of wiring work and to facilitate the wiring work. The rising portion 130 is thinner than the outer rising portion 120 in order to facilitate the inward tilting deformation and to give elasticity to the rising portion 130. Further, for the same reason, a pair of concave portions 135 extending along both sides of the inner rising portion 130 are formed on the surface of the bottom plate portion 110.

The electromagnetic wave shielding means 300 includes a cavity 150
Conductive materials 301 and 302 attached to at least the outer surface in a state where the base portion 100 and the cover portion 200 are combined as shown in FIG. 1 so as to surround the electric wires (not shown) accommodated therein. .

The conductive materials 301 and 302 are metal foils. The conductive materials 301 and 302 are affixed to at least the portion to be the outer surface (to be described in detail below) by fixing means such as an adhesive or a double-sided adhesive tape. The conductive material 30
The metal foils 1 and 302 may be metal foil tapes with an adhesive, in which case the adhesive or the double-sided adhesive tape is not required.

The outer surface includes an outer surface on the cover part 200 side and an outer surface on the base part 100 side. Cover part 20
The outer surface on the 0 side is the entire surface of the top plate portion 210 of the cover portion 200 and the portion on the back side following the entire surface.
Say up to near the outside. As the boundary of the outer surface on the cover part 200 side, the tip of the rising part 120 is the cover part 20.
Since the base portion 100 and the cover portion 200 are in contact with each other, a region in contact with the back surface of the reference numeral 0 is not included in the outer surface.

On the other hand, the outer surface on the side of the base portion 100 is the entire rear surface of the bottom plate portion 110 and the portion on the front surface side following the entire surface, up to the vicinity of the tip of the rising portion 120. As the boundary of the outer surface on the side of the base portion 100, the region of the leading end of the rising portion 120 abutting on the back surface of the cover portion 200 is not included in the outer surface.

However, the boundary between the outer surface on the cover 200 side and the outer surface on the base 100 side is
It is needless to say that the electromagnetic wave shielding effect is higher when the layers 02 and 301 are provided so as to be in contact with each other. Therefore, the conductive material 302 is provided so as to extend to a region where the leading end of the rising portion 120 contacts the back surface of the cover 200. On the other hand, the conductive material 301 is provided so as to extend to the region of the leading end of the rising portion 120 that contacts the back surface of the cover 200.

In the electric wire protection member 10 according to the embodiment of the present invention thus configured, wiring is performed as follows.

First, before fixing the wire protection member 10 to the floor or the like to which it is fixed, the wire protection member 10 is cut into a required size. At this time, the base 10 of the wire protection member 10
The cover 0 and the cover 200 are made of synthetic resin, and the conductive materials 301 and 302 of the electromagnetic wave shielding means 300 are also easily cut by using metal foil. Therefore, the cutting can be easily performed with a general saw or cutter. It is possible in a short time. The base portion 100 after the cutting process is attached to a fixed floor or the like by a fixing means such as a double-sided adhesive tape or a nail.

Next, an electric wire (not shown) is accommodated between the rising portions 130, 130 inside the base portion 100, and the cover portion 200 is attached.

When the cover 200 is attached, the cover 20
One of the ridges 220 on both sides provided on the back surface of the base portion 100 is fitted into one of the concave grooves 140 provided on the front side of the base portion 100. As a result, the cover 2 is placed on the base 100.
00 is in an inclined state, so that the other ridge 220 contacts the rising portion 130 located inside the other groove 140. Here, the protruding ridge 220 has a front end portion inclined outward and substantially downward, and thus abuts the outer end of the upper surface of the rising portion 130 located inside. Further, this contact portion is formed by the vertical plate portion 130 of the rising portion 130.
At a boundary portion 130c between a and the horizontal plate portion 130b, it is curved in a substantially arc shape.

Therefore, when the cover portion 200 is pressed from above, the other ridge 220 tilts the rising portion 130 inward and is fitted into the other groove 140. When the other ridge 220 is fitted into the other groove 140, the rising portion 130 has returned to the state before the tilt.

Thus, the work of attaching the cover part 200 is easily performed. The ridges 22 fitted in the concave grooves 140
In the case of 0, since the middle portion is formed in a substantially rectangular shape with a curve, it is difficult to fall out of the concave groove 140 even though the front end portion is directed right below.

When the attachment of the cover part 200 is completed, the electric wire is accommodated in the cavity 150 of the electric wire protection member 10, and the wiring work is completed. Since the conductive materials 301 and 302 are provided so as to surround the electric wires accommodated in the cavity 150, the electromagnetic waves from the electric wires to the outside of the electric wire protection member 10 are effectively shielded. In addition, the wire protection member 1
Electromagnetic waves that try to enter the inside of the electric wire protection member 10 from outside the zero are also effectively shielded.

In the electric wire protection member according to the embodiment of the present invention, the range in which the conductive materials 301 and 302 are provided is, for example, although the electromagnetic wave shielding effect is slightly reduced.
You may change so that it may reduce as follows. The conductive material 302 is not provided in a region where the leading end of the rising portion 120 contacts the back surface of the cover 200. On the other hand, the cover 20
The conductive material 301 is not provided in the region of the leading end of the rising portion 120 that is in contact with the back surface of the zero. Further, the conductive material 302 may not be provided on the entire back surface of the cover unit 200, or the conductive material 301 may not be provided on a region other than the back surface of the base unit 100.

In the case of the electric wire protection member according to the embodiment of the present invention, the conductive material 301 attached to at least the outer surface in a state where the base portion 100 and the cover portion 200 are combined as shown in FIG. , 302, but as shown in FIG. 3, conductive materials 303, 304 attached to at least the inner surface may be used instead of the conductive materials 301, 302 attached to the at least outer surface.

The inner surface is a surface around the cavity 150 and includes an inner surface on the cover part 200 side and an inner surface on the base part 100 side. The inner surface on the side of the cover 200 is the top plate 2
10, two horizontal plate portions 1 of the base portion 100
It refers to the area during which the tip of 30b abuts. On the other hand, the inner surface on the side of the base portion 100 refers to a region between the two rising portions 130 of the base portion 100 which is continuous with the region in FIG.

As in the case of the conductive materials 301 and 302, the boundary between the inner surface on the cover part 200 side and the inner surface on the base part 100 side is made of the conductive materials 303 and 304, respectively.
It is needless to say that the electromagnetic wave shielding effect is higher when they are provided in layers and brought into contact with each other. Therefore, for example, the conductive material 304 is not only a region on the inner surface on the cover portion 200 side but also a region following the inner surface, and the back surface of the top plate portion 210 where the two horizontal plate portions 130b of the base portion 100 abut. Is also provided to extend to the region. In addition, the conductive material 303 is provided not only in the region of the inner surface on the base portion 100 side but also in the region following the inner surface, and the horizontal plate portion 1 which is in contact with the back surface of the top plate portion 210.
It also extends to the area 30b.

Of course, the conductive materials 303 and 304 may be provided only on the inner surface on the base portion 100 side and on the inner surface on the cover portion 200 side without being provided in an overlapping manner.

Further, the conductive materials 303 and 304 may be further extended, and in extreme cases, may be provided so as to reach the outer surface region where the conductive materials 301 and 302 are provided. Good. That is, the base section 100 and the cover section 200 may be provided with a conductive material all around. In this case, the ridge 220 and the ridge 220
The conductive materials 303 and 304 also
Is extended.

However, when the conductive materials 303 and 304 are metal foil, the conductive material 3
The provision of 03 and 304 makes the fitting force smaller than the case where they are not provided. From this, for example, the conductive material 30
3, 304 may not be provided in the ridge 220 and the concave groove 140. In the case where the conductive materials 303 and 304 are provided in the convex ridge 220 and the concave groove 140, and when the fitting force is insufficient, for example, fine surfaces are formed on the surfaces of the convex ridge 220 and the concave groove 140. The unevenness may be provided to compensate for the insufficient fitting force.

In the case of the electric wire protection member according to the embodiment of the present invention, the conductive materials 301 to 304 are made of metal foil, but may be made of a conductive material such as a conductive cloth instead.

In the case of the electric wire protection member according to the embodiment of the present invention, the electromagnetic wave shielding means includes a conductive paint or the like applied to at least the outer surface or the inner surface in a state where the base portion and the cover portion are combined. It may be a conductive material. That is, a conductive material such as a conductive paint may be applied instead of the metal foil.

Therefore, in this case, the conductive materials 301 to 304 are conductive materials such as a conductive paint. The conductive paint is obtained by mixing, for example, carbon black or metal powder with the paint. The metal powder is a powder of a metal such as aluminum, nickel, copper, and silver. As the metal powder, it is preferable to select a metal powder which has high conductivity, is hardly oxidized, and is electrically stable.

In the case of the electric wire protection member according to the embodiment of the present invention, the electromagnetic wave shielding means is, as shown in FIG. The sheet-like conductive material 305 may be used.

An adhesive such as a hook-and-loop fastener (not shown) is attached to the conductive material 305 in the form of a sheet.
5 are provided at both ends in the longitudinal direction (the front-back direction of the paper surface of FIG. 4). The bonding means may be a double-sided adhesive tape or the like provided on one end side in the elongated direction. The conductive material 305 may be, for example, not only a metal foil and a conductive cloth, but also a conductive material 305 obtained by attaching a reinforcing insulating sheet to this.

The conductive material 305 is formed in a cylindrical shape by the bonding means, and accommodates an electric wire inside the cylindrical shape.

In the case of the electric wire protection member according to the embodiment of the present invention, the base portion 100 and the cover portion 200 are made of a synthetic resin, but may be made of another material. It is preferable that this other material be easy to cut.

In the case of the electric wire protection member according to the embodiment of the present invention, the electromagnetic wave shielding means comprises a base portion 100 formed by mixing a conductive material with a non-conductive material, and a cover portion 200. It may be. Non-conductive materials are
A synthetic resin or an equivalent material which is easy to cut is preferable.
The conductive material may be carbon black, metal powder, or the like as in the case of the conductive paint described above.

In the case of the electric wire protection member according to the embodiment of the present invention, the electromagnetic wave shielding means may of course combine the above-mentioned constitutions.

In the case of the electric wire protection member according to the embodiment of the present invention, it is assumed that the surface of the cover part 200 is not provided with a slip, but of course, small irregularities for the slip are arranged in the circumferential direction. It may be provided.

As described above, the electric wire protection member according to the embodiment of the present invention has been described as being separable into a base portion and a cover portion. In addition, as shown in FIG. 5, for example, a base 500 and one end 50 of the base 500 are provided.
It is apparent that the above-described respective electromagnetic wave shielding means (not shown) may be applied to a non-separable type wire protection member including the cover portion 550 extending from the 0A side.

Since the electromagnetic wave shielding means in this case can be easily understood by referring to the above-mentioned electromagnetic wave shielding means, the description is omitted, but the base portion 500 and the cover portion 550 of the non-separable type wire protection member are omitted.
The definition of the outer surface and the inner surface will be described below.

The non-separable type wire protection member has an outer shape
It has a substantially trapezoidal shape. The electric wire 900 is accommodated in a cavity 525 formed between the base part 500 and the cover part 550, as shown in FIG.

The locking means 501 is a locking recess, and the locking means 551 is a locking claw. As shown in FIG. 5A, the cover portion 550 can be opened and closed with respect to the base portion 500 at a portion near the base portion 500 of the cover portion 550.

For this purpose, the electric wire protection member is formed by so-called two-color molding, for example, by the following material. The material of the base part 500 and the locking means 551 of the cover part 550 is

Fixed to 00.

The outer surface of the non-separable type wire protection member referred to as the electromagnetic wave shielding means starts from point A in the state where the base portion 500 and the cover portion 550 are combined as shown in FIG. This is the outer circumference that ends with A. Similarly, the inner surface referred to by the electromagnetic wave shielding means is a surface around the cavity 525 shown in FIG. Of course, in addition to the outer surface and the inner surface, for example, by extending the conductive material also in a region where the locking means 501 and the locking means 551 are in contact with each other, the electromagnetic wave shielding effect can be enhanced. Do.

It goes without saying that the wire protection member according to the embodiment of the present invention may have a shape other than the above. For example, an outer shape like the wire protection member of FIG. 5, that is, a substantially trapezoidal shape may be applied as the outer shape of the wire protection member separable into the base portion and the cover portion described with reference to FIG. In this case, for example, the base portion and the cover portion are provided with locking means on both sides along the longitudinal direction. The locking means is, for example, a locking recess provided on the base or the cover, and a locking claw provided on the cover or the base.
