Abstract

PURPOSE:To obtain work ability and safeness by using a mat obtained by forming grooves having depth capable of storing plural cables on a sheet member for laying signal cables for an electronic computer or a data communication apparatus on a floor surface. CONSTITUTION:Grooves 2X of the X direction and grooves 2Y of the Y direction are formed on the sheet member 1 and the crossing parts of the grooves 2X and 2Y are connectec to each other. An arc-like connection groove 2R with a curvature for connecting both the grooves smoothly to each other is formed on the crossing part of the grooves 2X, 2Y so that a signal cable 3 can be extended straightly on the groove 2X. Consequently, the signal cable 5 can be applied without curving it sharply on the way and the mat is effectively used for optical fiber cables or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a mat for use in laying signal cables for electronic computers, data communication devices, etc.

[Prior art]

In the past, in computer centers and the like, equipment was often installed as a raised floor on the concrete floor of the room, and signal cables for connecting devices were laid between the concrete floor and the raised floor. However, this method increases the cost of setting up a raised floor, and
There was a problem that wiring work was not easy.

In recent years, a method has also been adopted in which signal cables are laid directly on concrete floors and carpets are laid on top of the signal cables. Although this method simplifies the installation work, the signal cable is subject to the weight of the carts of people walking on the carpet, so it is necessary to provide the signal cable with a relatively thick protective coating that can withstand the load. The problem was that it was expensive. In particular, when using an optical fiber cable as a signal cable, if a thick protective coating is required, the characteristics of the optical fiber cable, such as its small diameter and light weight, cannot be fully utilized. There is also the disadvantage that unevenness occurs on the surface of the carpet.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a signal cable laying mat that can solve the above-mentioned problems.

[Summary of the invention]

The signal cable laying mat according to the present invention has grooves deep enough to accommodate one or more signal cables in the sheet member (base material).
The signal cable can be easily laid by laying this mat on the floor and extending the signal cable through the groove.

[Embodiments of the invention]

The first is a perspective view showing an embodiment of the present invention, and 1 is a sheet member as a base material of the mat. This sheet member is made of a material that has enough strength to withstand a certain amount of weight.

A groove 2X in the X direction and a groove 2Y in the Y direction are formed in the sheet member.

The 2Y intersections are interconnected. Therefore, the signal cable 8 can be linearly extended in the groove 2X (or BY) as shown. At the intersection of the grooves 2X and 2Y, an arcuate connection 1'112R with a certain curvature is formed to smoothly connect both grooves to each other. Therefore, the signal cable 5 can be smoothly extended in order through the X-direction l1il12X, the connection groove 2R, and the Y-direction groove 2Y as shown in the figure, without sharply bending the signal cable 5 in the middle. In the case of a signal cable using conductor wire, it is possible to bend it at right angles at the intersection of grooves 2X and 2Y, but if the original fiber cable is bent at right angles, there will be problems such as damage and an increase in optical attenuation 1. . In order to deal with this problem, the above connection @2R is provided, and the radius of curvature of this connection groove 2R is
Approximately 10% of the outer diameter of the optical fiber cable to be installed
In general, good results can be obtained if it is done to a certain extent.

In addition, the depth and width of the grooves 2X, 2Y and the connection groove 2R (hereinafter collectively referred to as groove 2 as necessary) are such that when at least one signal cable is accommodated, the signal cable protrudes from the surface of the sheet member 10. You can decide not to.

Signal cables can be easily laid using this mat. That is, the installation work can be carried out simply by laying the mat directly on, for example, a concrete floor, extending the signal cable into the groove 2 as shown in the figure, and then laying a general carpet on top of it. Moreover, since the 1M cable is accommodated in the groove 2 and does not protrude from the surface of the sheet member 10,
Almost no unevenness occurs on the carpet 6, and even if a person walks on the carpet 6, the load is not directly applied to the signal cable, so there is no need to apply a thick protective coating to the 1g cable, resulting in an inexpensive signal cable. can be used. Furthermore, as in the illustrated signal couple 5, there are cases where it is desired to bend the No. 1G cable in the middle and lay it, but since the arc-shaped contact g groove 4 is provided, the No. 1G cable can be bent into an arc shape without difficulty.

Similarly, in this embodiment, the fermenters 2X and 2Y are orthogonally arranged, but grooves extending in two or more directions intersecting at any angle may be provided, or grooves may be provided in only one direction depending on the application. It's okay. Furthermore, the grooves do not necessarily have to be straight.

In addition, in this embodiment, the cross-sectional shape of the groove 2 has the same width E from the bottom to the upper end opening as shown in Figure 5 (A) of fJ2, but it has an inverted triangular shape as shown in Figure (B). It is also possible to have a cross-sectional shape, or to have an lrV surface shape with a narrow opening, as shown in FIG. In general, the surface shape and dimensions of the groove 20M may be appropriately determined depending on the cross-sectional shape and unbreakability of the signal cable to be passed through the groove 2. If the cross-sectional shape of the opening is cut as shown in Figure 2 (V→ or ), it is possible to prevent the <YR cable from floating up from the groove 2, and the protection of the No. 1G cable from carts is further ensured. Can be done.

Now, depending on the type of signal cable, a shield is required to prevent the influence of foreign noise, but according to the mat of the present invention, this shielding can be easily applied. For example, as shown in FIG. 8, if JVI 7 made of a conductive material for shielding is formed on the inner surface of the groove 2, the shielding effect can be maintained.

Such a layer 7 can be easily formed by, for example, pasting aluminum foil or vaporizing a conductive metal. Further, a conductive material is used as the material of the sheet member 1,
A shielding effect can also be achieved by making the entire mat 4-electric.

〔Effect of the invention〕

Since the present invention is as described above, it is possible to easily install a high-speed cable at a lower cost than when using a raised floor, and it is possible to easily install a 1g There is no need to apply a thick protective coating to the signal cable, an inexpensive signal couple can be used, and many advantages can be obtained, such as eliminating unevenness on the carpet surface.
