Abstract

PURPOSE:To seek to obtain excellent workability and improve protection against outside flaw and appearance beauty by covering plural cables coated with insulators in a body with hard synthetic resin material so as to form a housing having streightening property. CONSTITUTION:For a cable 1 for exposed wiring, two IV parts (cables coated with insulators) 2, 3 are arranged at the specified intervals in parallel and covered with hard synthetic resin in a body, thus a housing 4 having a streightening property is formed. And the back of a housing 4 is made in a flat mounting face 5 so that it may be fit for made faces such as wall, ceiling, etc., and fixed easily and securely in that shape. Further, a concave groove 6 is formed streight at the center of IV parts 2, 3, thus it is so considered that a nail 7 may be driven easily. Since the housing 4 which has a streightening property is formed by covering the IV parts 2, 3 with hard synthetic resin like this, it has resistance against outside flaw by a cutter, etc., and linear property, so it provides a beautiful appearance and its wiring work can be executed simply and efficiently, and then workability for the dressing mole wiring is excellent and the weight is reduced and the material is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to electric wires that are exposed on the construction surface and used for wiring during electrical outlet expansion work and the like.

(Prior art) Conventionally, VVF (600V vinyl insulated vinyl sheath cable flat type) exposed wiring wires have been generally used for exposed wiring.As shown in FIG.
is fixed to the construction surface with steps/l/32, etc., and decorative molding wiring as shown in FIG. 8 is performed. This decorative mall wiring is to run VVF [line barrier] inside the decorative mall road consisting of pace and cap type. Usually, double-sided adhesive tape is pasted on the back side of the base field, and this is temporarily attached to the construction surface. After fixing it, Machida etc. are driven in to firmly fix it vertically, vvF electric @ 31 is placed on top of the base, and a cap type is attached.

(Problems to be Solved by the Invention) Conventional V%'F [wire railings] are wound into a coil and stored in a stable state, so the curls cannot be removed during use.
Even in straight sections, there is a problem that meandering occurs as shown by the two-dot chain line in Fig. 7, making it unsightly.In addition, it is not only aesthetically pleasing, but also has the disadvantage of being susceptible to damage from knives, etc., such as conspicuous dirt during storage. Also, in the makeup mall, V
VF [Wire 31's drawbacks can be solved, but wiring work requires a lot of time and effort, and there are problems with workability, and the total length of the wiring requires various decorative moldings, so it is not economical. It has the disadvantage of being inferior.

This invention was made in view of the above-mentioned problems, and its objectives are: 1. To provide an exposed wiring electric wire that has good workability, protects against external damage, improves aesthetics, is economical, and has straightness.

Means for Solving Problem C) This invention covers a plurality of insulated electric wires C (hereinafter referred to as IV section) integrally with a hard synthetic resin material to form an outer structure with straightness. It has a covering. Incidentally, one surface of this outer cover is a plane parallel to the IV section, so that it can be easily fitted and fixed to the construction surface.

Further, the IV portions are arranged in parallel at regular intervals.

(Function) According to the present invention, since the electric wire has straightness, it is directly fixed by driving IV nails between the wires, and only the ends of the outer sheath are removed from the portion to be connected to a wiring device such as an outlet. In addition, part of the outer covering of corners, entrance angles, exit angles, etc. is removed, exposing the IV part and making the curve correspond to the shape of the corner.
Cover only the exposed part of the V section with a cosmetic cover, etc.

(’ji’ example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a first embodiment of the present invention, in which 1 is an exposed wiring wire according to the present invention, in which two IV parts (insulated wires) 2 and 3 are arranged in parallel at a predetermined interval. and is integrally covered with a hard synthetic resin material to form an outer cover 4. The back surface of the outer cover 4 is a flat mounting surface 5.
It has a shape that is suitable for construction surfaces such as walls and ceilings, and allows for easy and reliable fixing. Further, on the surface, there is a concave groove 6 located in the middle of the IV part 2.3 and parallel to it.
is formed so that the nail 7 can be driven easily.

FIG. 2 shows a second embodiment of the present invention, in which the exposed wiring wire 1 has a hard synthetic resin sheath 4 covering an IV portion 2.3 whose cross-sectional shape is It has a substantially semi-cylindrical shape, has a flat mounting surface 5, and has both IV parts 2.3.
Nail holes 8 are provided between the electric wires at predetermined intervals in the longitudinal direction of the electric wires, passing through the electric wires from the front and back.

Therefore, in both the first and second embodiments, when wiring this, after cutting it to the required length, the connection part to the M distribution device etc. is made by cutting off the end of the outer sheath 4 and connecting it to the IV. The part 2.3 is exposed and its insulation coating is peeled off. In addition, for curved portions such as corners of walls, exit angles, entrance angles, etc., as shown in FIG. .3, and this exposed IV part 2
A and 3A may be covered with the decorative cover 10. This decorative cover 10 is for a corner and consists of a lower base n and an upper cover branch, and conventional accessories for decorative moldings can be used.

FIG. 4 shows the decorative cover rib for the entrance angle, which has a generally simplified shape and consists of a base 14 and a cover 15. Further, FIG. 5 shows a decorative cover 16 for a protruding angle, which has a substantially inverted shape and consists of a base ν and a cover cover.

In addition, when wiring, apply double-sided adhesive tape to the mounting surface 5 of the outer sheath 4 in advance, and after temporarily fixing it to a wall surface, etc.
It is preferable to fix the electric wire l with nails 7.

Figure 6 shows an example of using the wl electric wire according to the present invention for wiring to a vertical wall in a room, including a start-up wiring device from the distribution board 19, a wiring on the outside of the ceiling, and a drop-down wiring device to the additional outlet ρ.

Then, a corner decorative cover 10 is attached to the curved part of the rising wiring and the falling wiring device and the turning green wiring 4 on the outer surface of the ceiling, and the corner corner cover 1O is attached to the corner of the turning green wiring 4 on the outer surface of the ceiling. A decorative cover for entering angles and a decorative cover for exiting angles 16 are attached to the terminal, allowing for neat wiring in terms of appearance.

In the above embodiment, since the mounting surface 5 is flat and is provided with grooves 6 or nail holes 8, attachment to the construction surface is extremely easy. 4. Materials can be saved, and weight reduction and economical efficiency can be improved.

Note that the decorative cover attached to the υ portion is not limited to the above example, but may also be a cover of other shapes or a flexible cover that is bendable, and a straight cover attached to the connecting portion of the exposed wiring wires 1. Of course, a decorative cover will be adopted.

(Effect of the invention) As described above, the exposed wiring wire according to the present invention has r
The V part is covered with a hard synthetic resin material to form an outer cover with straightness, so it is resistant to damage caused by knives, etc., and the straightness gives it an aesthetic appearance and makes wiring work easier. It can be done more efficiently, has better workability than decorative molded wiring, is lighter in weight, saves on materials, is relatively inexpensive, and is completely inferior in terms of aesthetics and safety. Therefore, the economical efficiency of wiring work can be improved.
