Description

[Detailed description of the device]

The present invention relates to an exposed wiring cable laid on a floor, a wall or the like. More specifically, the present invention relates to an exposed wiring cable including a cable body in which a core wire is integrally incorporated, and a cable fixing material fitted to the cable body.

[0002]

[Prior art]

 In recent years, with the use of various electronic devices, the demand for wiring indoors and outdoors has been increasing, and therefore, it is widely practiced to provide additional wiring, which cannot be covered by existing wiring. . In this case, generally, a gutter-shaped molding made of synthetic resin is first attached to the floor or wall along the route to be wired, then the cables with the required number of cores are stored in it, and the molding cover is placed over it. It is covered with a cover to complete the construction.

[0003]

[Problems to be solved by the device]

 However, in the conventional wiring work using such a mall, first, the mall is installed along the route to be wired, and then the cable to be routed along the route is further laid, and the mall cover is further installed. Since it requires three steps of installation, it not only takes time for the construction, but also has the drawback that the construction cost is considerably high.

Further, since the molding used is made of plastic, its mechanical strength is weak and the molding cover is cracked well, so that the molding cover has to be replaced frequently in order to maintain the cable. Have

The present inventor solves the drawbacks of the conventional wiring work, and provides an exposed wiring cable that can be installed in a simple process to save labor and that the wiring can be reliably maintained after the installation. That is the issue.

[0006]

[Means for Solving the Problems]

 The exposed wiring cable according to the present invention is composed of a cable main body in which a required number of core wires are embedded and a cable fixing material having an adhesive layer on the back surface, and a fitting groove is provided on the bottom surface of the cable main body. The cable fixing member is provided with a fitting protrusion corresponding to the fitting groove, and the cable main body and the cable fixing member are fitted to each other (Claim 1).

In addition, the exposed wiring cable has a cable body in which a required number of core wires are embedded and integrally formed, and has a fitting groove on the bottom surface thereof, and a fitting for fitting the fitting groove on the surface. A cable fixing material having a protrusion may be used, and the cable body may be clamped from both sides by stoppers that are attached in advance to a cable laying position, and a mounting groove that engages with the stoppers may be formed in the cable body ( Claim 2).

Here, when the fitting protrusion is continuously provided in the extending direction of the cable fixing material, it is desirable to make a cut at a right angle to the extending direction (claim 3).

[0009]

[Action]

 Therefore, in the structure according to claim 1, when the cable is attached to a desired floor surface, wall surface, or the like, the cable fixing member is provided on the back surface with the cable body and the cable fixing member fitted together. The adhesive layer may be attached to a desired laying location, which allows the cable to be easily routed in a short time. Also, since the core wire itself is embedded in the cable body, the cable is mechanically strong.

Further, according to the configuration of claim 2, even when it is difficult to attach the cable fixing material to the floor surface, the wall surface, etc., the fastener is attached to the laying position in advance and the cable fixing material is fitted. If the cable main body is fitted into this stopper, the stopper is engaged with the mounting groove to firmly clamp the cable. In this case also, the cable is mechanically strong because the core wire itself is embedded in the cable body.

When the notch is formed in the fitting protrusion as in claim 3, the cable fixing member can be easily bent with the back surface facing inward.

【Example】

 An embodiment of an exposed wiring cable according to the present invention will be described below with reference to the drawings.

In FIG. 1, the exposed wiring cable is composed of a cable body 1 and a cable fixing member 7. As shown in FIG. 1 (a), the cable body 1 has a required number of core wires 6 embedded in the center of the cable body 1 in the extending direction, and the embedded core wires 6 are protected by an insulating material 5 around the periphery thereof. ing. Further, fitting grooves 3 and 4 are also provided on the bottom surface portion 2 of the cable body 1 along the extension direction.

On the other hand, as shown in FIG. 1 (b), the cable fixing member 7 has fitting protrusions 8 and 9 formed on its surface for fitting with the fitting grooves 3 and 4. . The fitting protrusions 3 and 4 are continuously formed in the extending direction, but the case where the cable fixing material 7 is wound around the drum with the back surface thereof inside, or is laid on a convex-shaped laying place is planned. Thus, the cuts 11 are formed at predetermined intervals at right angles to the extending direction.

The exposed wiring cable is formed by firmly fixing the cable main body 1 on the cable fixing member 7 by fitting the corresponding fitting grooves and fitting projections to each other.

Although various shapes of the fitting groove and the fitting projection are suitable, as another example, a projection of a predetermined shape (for example, a spherical shape or a cylindrical shape) is formed on the surface of the cable fixing member 7 at a predetermined interval. It is possible to form each of them and provide the cable main body 1 with a concave portion that fits with this projection. Further, in the embodiment shown in FIG. 1, the fitting protrusions 8 and 9 and the fitting grooves 3 and 4 are provided in the central portion and in the vicinity of both edges. It may be changed according to the required width of the main body, the mounting strength, and the like. Furthermore, in the embodiment, the fitting projection 8 and the fitting groove 3 at the central portion and the fitting projection 9 and the fitting groove 4 near both edges have different cross-sectional shapes, but several kinds of fitting grooves are not necessarily required. It is not necessary to use a fitting protrusion or a fitting protrusion, and it is possible to use one type in some cases.

FIG. 2 illustrates an embodiment in which three core wires 6 are provided, and the fitting groove 3 in the central portion and the fitting protrusions 8 corresponding to the fitting groove 3 are formed at two positions respectively.

An adhesive layer 10 is provided on the bottom surface of the cable fixing material 7, and is usually protected by a release material made of paper or a thin synthetic resin film. The release material is peeled off from the cable when the cable main body 1 and the cable fixing material 7 are integrally fitted as shown in FIG. 2 and then the fitted cable is installed at a desired position. . As a result, the cable is directly bonded and fixed to the wall surface or floor surface by the adhesive layer exposed on the back surface.

As described above, since the cable according to the present invention is directly adhered and fixed to the wall surface or floor surface to be installed, the material of the cable body 1 has the strength required for a normal exposed wiring cable. Flexibility against impact and external pressure is required, and cable materials used in existing cables such as VCT, VCTF, and VVF are suitable.

In order to manufacture the cable according to the present invention, the core wire 6 and the insulating material 5, and the protective material and the cable fixing material 7 forming the cable body 1 which covers the core wire 6 are simultaneously drawn in from one of the molds and pressed. Mold and mold by continuously drawing from the die outlet.

In this case, the cable fixing member 7 is continuously used as a guide member, and the cable main body having an appropriate length is integrally formed on the cable fixing member 7 by the above-described method, so that the cable fixing member 7 is continuously formed on the continuous cable fixing member. It is also possible to make a cable by mating the cable bodies, or to make a cable by intermittently mating the cable body of an appropriate length on a continuous cable fixing material. Yes, you can easily obtain the desired length of cable by winding such a cable around the drum, cutting the required length of cable when using it, or cutting only the cable fixing material without the cable body. Therefore, the construction time can be significantly reduced.

Even when the cable fixing member 7 is laid on a convex laying place using such a cable, the cable fixing member 7 has the notches 11 formed in the fitting protrusions 8 and 9 as shown in FIG. As described above, when each notch 11 portion is widened, the notch 11 can be easily bent with the back surface inside and can be closely attached to the laid portion. On the other hand, when crawling on a concave laying place, the cable fixing member 7 has a structure in which the upper surface is inward and is difficult to bend because the fitting protrusions 8 and 9 are continuously formed. However, in this case, as shown in FIG. 3, the fitting projections 8 and 9 may be partially cut off at a portion corresponding to the concave shape. As a result, the cable fixing member 7 can be bent with its upper surface facing inward, and can be brought into close contact with the concave installation site.

FIG. 4 shows another embodiment of the exposed wiring cable. In this embodiment, the basic structure of the cable main body 1 and the cable fixing member 7 is the same as that of the exposed wiring cable shown in FIG. 1, and therefore the same parts are designated by the same reference numerals and the description thereof will be omitted. Only different parts will be described. To be more specific, a wedge-shaped mounting groove 12 for engaging a stopper described later is continuously formed on both side surfaces of the cable body 1 along the extending direction.

The stopper 13 is formed, for example, by processing a metal plate. In the case of a simple structure, the stopper 13 is fixed to the laying place with the screws 16 or the like and the cable is installed upright from both ends thereof. The main body 1 is sandwiched by the sandwiching portions 15 and 15. In this embodiment, the screw is fixed at one place in the center of the fixing portion, but it may be fixed at two or more places to prevent the stopper 13 from rotating.

Further, the holding portions 15 and 15 of the stopper 13 are provided with a space substantially equal to the width of the cable body 1 and bulge inward at the tip to engage with the mounting groove 12 of the cable body 1. Possible engagement projections 17 are formed. It is desirable that the tip of the engaging projection 17 has a shape that is widened outward so that the cable can be easily received.

In such a configuration, it is effective when the adhesive layer 10 of the cable fixing material 7 alone cannot secure a sufficient attachment strength of the cable or when the adhesive layer 10 cannot be laid. The stopper 13 may be previously attached to the stopper 13 with the screw 16, the cable may be fitted into the stopper 13, and the engaging projection 17 may be engaged with the mounting groove 12 of the cable fixing member 7. As a result, the cable body 1 is firmly clamped by the clamp portions 15 of the stopper 13, and the cable can be laid securely at a desired position. In this case, as long as the cable is fixed by the fastener 13, a strong laying state can be obtained without the adhesive layer 10 of the cable fixing material 7. However, when laying the cable by adhesion together, It is preferable to leave the adhesive layer 10 as it is. Needless to say, it is desirable to similarly form the notches shown in FIG. 1 in the fitting protrusions 8 and 9 of the cable fixing member 7.

As the core wire 6 of the cable according to the present invention, in addition to one metal wire, various shapes such as a twisted wire or a bundle of many bundles can be used, and it can also be used for a glass fiber wire. Is.

[0028]

[Effect of device]

 As described above, according to the exposed wiring cable according to the first aspect, it is possible to directly install and fix it on the wall surface or floor surface to be installed, and not only can the construction time be significantly shortened, It has sufficient strength and flexibility corresponding to it, and has enough strength to withstand impact and pressure during use.

Further, according to the second aspect of the invention, when the stopper is engaged with the mounting groove formed in the cable body so as to be sandwiched from both sides, the cable fixing material can be attached even in a difficult place. The cable can be wired reliably and in a simple process, and labor can be saved. Even in this case, it has a strength enough to withstand impact and pressure during use.

In particular, if the fitting protrusion is provided with a notch as in claim 3, the cable fixing member can be bent with the back surface inside, so that the molded cable can be easily wound around the drum, and It makes it easier to crawl the cable to the convex laying place.
