Abstract

PROBLEM TO BE SOLVED: To provide a low-cost cable where a plurality of core wires are collectively wired while each core wire is separated easily. SOLUTION: Wire cores, 1R, 1W and 1B are connected together with a connection member 2 at a prescribed interval in the length. Thus, each core wire is not required to be measured for length and separately cut at wiring, for efficient wiring operation with similar labor and time to when a single core wire is wired. Since no external cladding such as of a cab tyre cable is required, no labor of removing a cladding to expose a core wire is required at connection. To partially separate the core wire, the connection member is only required to be cut at several points using a cutter or nipper, with the work especially simplified compared with a flat cable. Since a plurality of core wires may be connected intermittently, manufacturing at a lower cost is possible compared with a cab tyre cable where a plurality of core wires are externally cladded and with a flat cable where tight contacting is required over the entire length direction of each core wire.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable composed of a plurality of core wires.

[0002]

2. Description of the Related Art Conventionally, when a plurality of electric wires such as IV wires (for example, three wires) are wired, for example, the length of each IV wire is measured one by one and individually cut, and then connected. I was doing work such as line entry. However, if the length was measured and cut in this way for each line,
The wiring work was inefficient because it took a lot of time and labor. Therefore, if a cable in which a plurality of core wires are bundled in advance, such as a cabtire cable in which a plurality of core wires are collectively covered with a cover, or a flat cable in which a plurality of core wires are arranged in a plane and adhered to each other is used, It is possible to efficiently wire the plurality of core wires in the same manner as when wiring a plurality of electric wires.

[0003]

However, for example, the above-mentioned cabtyre cable has a problem that the cost is high and the work of stripping the outer coating is required when the respective core wires are taken out, which is troublesome for the wiring work and the like. there were. Further, in the above-mentioned flat cable, since the core wires are adhered to each other over the entire longitudinal direction, there is a problem that it takes time and effort to separate the core wires when connecting the wires. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a plurality of core wires in a bundle and to separate the core wires extremely easily at a low price. Is to provide a cable.

[0004]

In order to achieve the above object, the present invention is characterized in that, in a cable composed of a plurality of core wires, the core wires are connected to each other at predetermined intervals in the longitudinal direction. Configured as a cable. Further, if the members used for connecting the core wires are made of an easily deformable material, for example, as shown in FIG.
As shown in (b), the cable can be easily rolled up and used, the space for wiring can be saved, and the cable can be flexibly dealt with according to the wiring location.

[0005]

According to the present invention, since the core wires are connected to each other, it is not necessary to measure the length of each core wire one by one and to cut the core wires individually, and to wire one core wire. It is possible to perform the wiring work efficiently with the same time and effort. In addition, since there is no need for an external coating such as a cabtire cable, there is no need to remove the coating to expose the core wire when connecting. Further, when part of each core wire is separated, it suffices to cut the connecting member at several places with a cutter, a nipper, etc., and the work is greatly simplified as compared with a flat cable. Further, since it is only necessary to connect a plurality of core wires intermittently, it is possible to manufacture at a lower cost than a cabtyre cable in which a plurality of core wires are covered with an outer coating, or a flat cable in which the core wires are adhered in the entire longitudinal direction. is there.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments and examples of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention. It should be noted that the following embodiments and examples are merely examples embodying the present invention and are not of the nature to limit the technical scope of the present invention. Here, FIG. 1 is a schematic diagram showing a schematic configuration of the cable A1 according to the embodiment of the present invention, and FIG.
[Fig. 3] is a cross-sectional view of the cable A1. As shown in FIG. 1, the cable A1 according to the present embodiment has three IV electric wires 1R, 1W, 1B having coatings colored red, white and blue.
(An example of a plurality of core wires). Also, each IV
The electric wires are 250 mm apart in the longitudinal direction (an example of predetermined intervals).
Then, the connection members 2 connect at points. The connection member 2 may be made of the same material as the coating of each IV electric wire or a different material, and is made of an easily deformable material such as vinyl or rubber. The connection method of the IV electric wires is, for example, by arranging the IV electric wires in close contact with each other in parallel,
The coating is welded by applying heat for each mm (the coating itself becomes the connecting member 2), or the separate connecting member 2 is attached to each I
A method of welding the V electric wires at intervals of 250 mm so as to connect them horizontally may be considered. In any case, it can be manufactured at a lower cost than a cabtire cable in which a plurality of core wires are covered with an outer coating, or a flat cable in which the core wires are closely attached in the entire longitudinal direction.

As shown in FIG. 2A, the cable A1 has each IV in a normal state (a state where no external force is applied).
The electric wires are connected so as to be arranged in a plane, but since the connecting member 2 is deformable, it can be easily rolled up and used as shown in FIG. 2 (b), thus saving wiring space. It is possible and can flexibly respond to the wiring location. In this cable A1, since each IV electric wire is connected to each other as described above, it is not necessary to measure the length of each IV wire one by one at the time of wiring and to individually cut each IV electric wire. It is possible to perform the wiring work efficiently with the same labor and time as in the case of performing. Also, since there is no external coating like the cabtire cable, there is no need to remove the coating to expose the core wire when connecting. Furthermore, each I
When a part of the V electric wire is separated, it suffices to cut the connecting member 2 at several places with a cutter, a nipper or the like, and the work is significantly simplified as compared with the flat cable.

[0008]

[Embodiment] The cable A1 is composed of three IV electric wires, but it is of course possible to compose two or four or more core wires. The connection interval is not limited to 250 mm, and each connection member 2 does not necessarily have to be a point connection, but may have some width as long as it can be easily disconnected. Further, it goes without saying that the connection of each core wire may be in the form as shown in FIG. 2B in the normal state.

[0009]

As described above, the present invention is configured as a cable including a plurality of core wires, wherein the core wires are connected to each other at a predetermined interval in the longitudinal direction. Therefore, it is not necessary to measure the length of each core wire one by one and to cut each separately when wiring, and the wiring work can be performed efficiently with the same effort and time as when wiring one core wire. It is possible. In addition, since there is no need for an external coating such as a cabtire cable, there is no need to remove the coating to expose the core wire when connecting. Further, when part of each core wire is separated, it suffices to cut the connecting member at several places with a cutter, a nipper, etc., and the work is greatly simplified as compared with a flat cable. Further, since it is only necessary to connect a plurality of core wires intermittently, it is possible to manufacture at a lower cost than a cabtyre cable in which a plurality of core wires are covered with an outer coating, or a flat cable in which the core wires are adhered in the entire longitudinal direction. is there. Further, if the members used for connecting the core wires are made of a material that can be easily deformed, the cable can be easily rolled up and used as shown in FIG. 2B, and the space for wiring can be saved. It is possible to adapt it flexibly according to the wiring location.
