Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an undercarpet cable laying method that allows easy installation, expansion, and layout changes.

[Technical background of the invention and its problems] As office automation advances, the undercarpet construction method, in which a flat cable is laid between the floor and the carpet, is used to make the power cables that supply power to various office equipment less conspicuous. has begun to be adopted.

Therefore, in this construction method, cable installation is carried out in the following steps.

1. Floor cleaning ↓ 2. Marking (determining cable installation position) ↓ 3. Bottom (cable receiving receiver) installation ↓ 4. Cable installation ↓ ↓←← Outlet box installation 1 Junction connection 5. Top shield installation ↓ 6. Laying the carpet In the above process, the work such as installing the outlet box and connecting one branch, which is done in the middle of steps 4 and 5, is extremely time-consuming as it includes work such as connecting connectors and insulation processing. It becomes. Therefore, laying the undercarpet cable requires a lot of effort and time, and once the undercarpet cable has been laid, it is not easy to add more or change the layout.

That is, in the conventional installation method, three devices 12 are arranged only on one side of the main line 11 shown in FIG. 4A, and from the installation layout of the undercarpet cable that supplies power to them, In order to change to the undercarpet installation layout in which one device is added to the other side of the main line 11 and power is supplied to each device including other devices whose position is shifted by the amount of the added i device, It is necessary to follow the steps shown in Figures A, B, and C. Note that 13 in the figure indicates a power source.

First, the main line 11 is cut at one branch point 14 and corner 15 as shown in FIG. 5A, and the main line is extended by a straight cable connection 16 as shown in FIG. As shown in the figure, making a branch connection to an additional device requires complicated work such as stripping off the insulation coating, connecting conductors, and performing insulation treatment for each connection point, so it is difficult to change the layout to accommodate the addition of one device. However, it takes about 4 hours.

[Objective of the Invention] The present invention has been made based on the above circumstances, and it is an object of the present invention to provide an undercarpet laying method that not only allows for easy laying, but also makes it easy to add undercarpet cables and change the layout after laying. It is an object.

[Summary of the invention] The undercarpet cable installation method of the present invention is as follows.

Prepare a unit of a certain length with plugs attached to both ends of the unit wire, and a cross-shaped, L-shaped, or T-shaped connector having a socket at the tip of each leg piece etc. to engage with each of the plugs, The present invention is characterized in that a line is configured using each of the units and each connector.

[Embodiment of the Invention] FIG. 1 shows an embodiment of the invention. In the installation method of the present invention, prior to installation, a flat cable is cut to the required dimensions according to the installation drawing to obtain the required number of unit wires 1, and connector plugs 2 are attached to both ends of the unit wires.
are attached to form the required number of units 3. In addition, as shown in FIGS. 2A, B, and C, there is also a cross-shaped connector 4 in which a connector socket 4a is attached to the tip of each leg.
, an L-shaped connector 5 having an L-shape and having a connector socket 5a attached to the tip of each leg, and a T-shaped connector 6 having a T-shape and having a connector socket 6a attached to the tip of each leg. Ru.

In the cable laying method of the present invention, the layout shown in FIG. 4A has two cross-shaped connectors 4 as shown in FIG. 3A.
A trunk line 11 is constructed using one L-shaped connector 5 and two units 3.

The power supply 13 and the main line 11 are connected to one cross-shaped connector 4 in the main line, and each device 12 and the main line are connected to another cross-shaped connector 4□ in the main line and an L-shaped connector 5 in the main line, respectively, by the unit 3. connected and configured.

According to the above installation method, the power source is branched to one device.

The structure of the trunk line does not require any peeling of insulators, connection between conductors, insulation treatment of connection parts, etc., and can be installed by simply inserting the socket of the unit into the connector.

To change the layout as shown in FIG. 4B, first connect the unit connected to the L-shaped connector 5 to the cross-shaped connector 4. One end of the unit wire 1 is connected to this connector 4 □, one end of the top piece of the T-shaped connector 6 is connected to the other end, and the unit separated together with the L-shaped connector 5 is connected to the top of the connector 4 □. Connect to the other end of the piece. Figure 3B
shows the state immediately before connection of the unit to the T-shaped connector 6 after the connection of the T-shaped connector 6 has been completed. Also.

Branching to additional equipment is accomplished by connecting the unit 3 to the equipment to the legs of the T-shaped connector 6.

[Effects of the Invention] As is clear from the above, in the undercarpet cable installation method of the present invention, straight connections and branch connections can be made by simply inserting the socket of the unit into the various connectors prepared. There is no need to perform any work such as peeling off the body, connecting conductors, or performing insulation treatment after connection. Therefore, the work of laying the undercarpet cable can be significantly simplified.

Furthermore, in the case of changing the wiring layout or adding equipment, unlike undercarpet cable lines laid using conventional laying methods, it is necessary to cut the cable, peel off the insulation, connect conductors, and insulate the conductors after connection. Any layout can be changed using the various prepared connectors and units without any processing, and equipment can be added quickly in the same way.
