Description

[Detailed description of the invention] This invention relates to a flat cable protection device.

Conventionally, as a flat cable used in an under-carpet wiring system, a cable in which a plurality of flat conductors 3 are embedded in a band-shaped insulator 2 has been used, as shown in FIG.

This flat cable 1 must be covered with a metal sheet to protect it from external mechanical forces. Conventionally, as shown in FIG.
is fixed to the floor. Adhesive tape 5 is 150m to 30m
Pasted at 0 n intervals. A lower surface protection sheet 6 is provided between the flat cape v1 and the floor surface.

However, as shown in Fig. 3, during the work of fixing the adhesive tape 5 to the tree, the flat cape A/1 and the metal sheet 4 that have already been laid may move from the determined position 1'. In addition, the work of pasting the adhesive tape 5 is required in addition to the work of laying the metal sheet 4, which requires time and effort.

Also, as shown in Figure 4, K, metal &-) 4 and flat cape A/
10 A bent portion 4a is formed along both side edges. Therefore, when an external force Q (Fig. 5) is applied to the metal 1/-) 4 from the outside, a compressive force is likely to be applied to the edge of the insulator 2 of the flat cape A/1. K11lil as shown
There is a problem that the edge 21 is destroyed and the conductor 3 is exposed, causing a short circuit with the metal sheet 4, which is dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to provide a flat cable protection device that is easy to install and provides reliable protection.

An embodiment of this invention is shown in FIG. That is, in this flat cable protection device, side edge tapes 7 are pasted on the floor along both sides of the flat cape 1L/10, which is laid on the floor via the bottom protection V-toro, and the upper surface of the flat cable 1 is covered with a band-shaped tape. It is covered with a metal sheet 8 and its both edges are attached to the upper surface of the side edge tape 7. Side edge tape 7Fi flat cape l
The thickness is the sum of the thickness of v1 and the thickness of the lower surface protection sheet 6. The side edge tape 7 is made of double-sided adhesive tape, and is prepared in advance with one side attached to a metal sheet 8 and a release sheet 9 (FIG. 7) attached to the other side. The metal sheet 8 to which the side edge tape 7 is attached is prepared by winding it into a roll.

During construction, first the flat cable 1 is laid on the floor via the lower surface protection sheet 6. Then, as shown in FIG.
The metal sheet 8 is then placed on the flat cape, 2/1, and gradually unwound to peel off the release sheet 9 little by little, the side edge tape 7 is attached to the floor, and the metal sheet 8 is fixed to the floor.

Metal on top! /-) While sequentially covering the metal S'
-) Since the side edge tape 7 affixed to 8 is fixed to the floor surface, the flat cable 1 that has already been laid will not move from the determined position. Moreover, it is only necessary to unwind the metal sheet 8 while peeling off the vertical sheet 9, and the metal V-
) 8 and fixing this metal V-gap 8 to the floor surface can be done at the same time, so the working time is shortened. Further, since the thickness of the side edge tape 7 is equal to the thickness Q of the flat cable 1 and the lower protective sheet 6, the metal sheet remains flat and no bends occur. Therefore, the metal sheet 8
Even if an external force is applied to the upper surface of the flat cable IK, the external force will not be locally concentrated, and the insulator 2 will not be destroyed and the conductor 3 will not be exposed. Therefore, there is no risk of short circuit between the conductor 3 and the metal sheet 8.

In addition, in the #1Ii3* example, the lower surface protection sheet 6 was provided, but if the lower surface protection sheet 6 is not provided, the side edge tape 7
is formed to have the same thickness as the flat cape A/1.

As described above, the flat cable protection device of the present invention includes a metal V-) formed wider than the flat cable laid on the floor and covering the upper surface of the flat cable, and both edges of the lower surface of the metal sheet. Since the lower surface is formed into an adhesive surface and is adhered to the floor surface, the large side edge tape is attached to the floor surface, so by preparing the side edge tape in advance by pasting the metal sheet, The work of covering the flat cable with the metal sheet and the work of fixing the metal sheet to the floor can be done simultaneously, making construction easy, and there is no problem of moving the position of the flat cable during the fixing work. Moreover,
The effect is that the external force applied from the top surface of the metal sheet after construction is completed does not locally destroy the insulation of the flat cable throughout the year, and there is no problem of short circuits between the conductor and the metal sheet.
