Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a distribution cable, and particularly to a distribution cable suitable for use in wiring under a carpet.

[Conventional technology]

Conventionally, when a wiring cable is routed under a carpet or the like and has a bent portion, the following method has been generally used.

As shown in FIG. 2A, the flat cables 1 are turned upside down and overlapped at the bent part.

As shown in FIG. 2B, the flat cables 1 are turned upside down and stacked on top of each other at the bent portion, and then turned over again and stacked on top of each other.

As shown in Figure C, the flat cable 1 is bent gently with a large bending radius at the bend.

[Problem that the invention attempts to solve]

As mentioned above, in the cables in Figure 2 A and B, the cables are inverted and bent, so the height is more than double, so if you cover it with a carpet, etc., the surface may become convex. There are drawbacks.

Further, in the case of FIG. 2C, the degree of freedom in wiring is extremely low because small bends cannot be made.

[Means for solving problems]

In view of the above-mentioned conventional drawbacks, the present invention provides a wiring cable that can form a bent portion with a small bending radius without doubling the height.
This means is a wiring cable in which a notch is provided in a covering member that covers a plurality of conductive wires so as to separate the plurality of conductive wires, and a regular piece is inserted into this notch.

[Effect]

Since the wiring cable has a notch in the covering member to separate the plurality of conductors, the notch is widened at the bent part, and the inner circumferential side is made to protrude inwardly. By doing so, the length of the path on the inner and outer circumferential sides is absorbed,
This prevents tensile force from being applied to the conductor due to the difference in length.

〔Example〕

FIG. 1 is a diagram for explaining an embodiment of a wiring cable according to the present invention.

In the figure, 1 is a flat cable, 2 is a conductor, 3 is a covering member, 4 is a notch, and 5 is a regular piece.

As shown in the figure, when wiring the flat cable 1 by bending it, by widening the notch 4 and making the inner circumference side part 3a of the covering member 3 protrude, the inner circumference side part 3b and Since the lengths of the inner peripheral portions 3a can be made the same, a bent portion can be formed with a small bending radius while keeping the height exactly the same. In addition, by inserting a regular piece into the notch 4, the shape at the bent portion can be fixed, so wiring can be performed smoothly.

〔effect〕

As described above, according to the present invention, it is possible to provide a wiring cable that can form a bent portion with a small bending radius while maintaining the same height.

Particularly in the case of an undercarpet distribution cable, the height remains the same, so no protrusions are formed on the carpet surface, and a uniform surface can be achieved.

[Brief explanation of the drawing]

FIG. 1 is an explanatory diagram of an embodiment of a distribution cable according to the present invention, and FIG. 2 is an explanatory diagram of a bending method using a conventional distribution cable. In the figure, 1 is a flat cable, 2 is a conductor, 3 is a covering member, 4 is a notch, and 5 is a regular piece.
