[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a low floor, double floor wiring that can flexibly support the use of many power supplies and telephones in business offices and the like.

[0002]

[Prior art]

 Almost all existing business offices and other indoor wiring for power supplies and telephones use floor-embedded pipes such as conduits and floor ducts, and the addition of power supplies and telephones due to layout changes and recent office automation. sometimes, really complicated floor on the exposed wiring because it is difficult to rewiring has been performed.

Recently, as the office environment has become more sophisticated, the rate of carpeting has increased, and an undercarpet wiring method has been adopted in which an ultra-thin flat cable is laid under the carpet. However, these methods are not qualified for construction because the products are not compatible between manufacturers, special tools and specialized knowledge are required for construction, or wiring management is required by double flooring. There were problems such as the need for an expert with

[0004]

[Problems to be solved by the device]

 Due to labor shortages and rising labor costs in the electric construction industry in recent years, demands for labor saving in construction work are only increasing. At the same time, even non-specialists are required to be able to handle products easily and safely and to obtain products of stable quality.

The present invention has been made to meet these requirements, and is a cable with a branch compet and a unit cable with a branch outlet that are produced in advance as a unit in which a branch cord and a cable are integrated. is there. At the construction site of a new or expanded / renovated office building, one end of this unit cable is connected to a distribution board or terminal board, and the entire unit is simply installed in a low double-floor space. The feature is that the outlet for power supply and telephone can be easily taken out.

[0006]

[Means for Solving the Problems]

 This device is configured by connecting a cable and a branch outlet, and accommodating the cable, the branch component, and the connection part thereof in an insulating box. Alternatively, it is a cable with a branch outlet that is integrally molded with an insulating compound. Furthermore, the unit cable with a branch outlet for a double floor is characterized in that it is unitized by providing a plurality of branch comparator connection portions by the same means as described above. The insulation box and the molded connection part are generally designed to have a compact size so that wiring can be performed on a low double floor.

The above cable with branch outlet and unit cable with branch outlet are produced in advance in a factory, and one end of the cable is connected to a distribution board or a terminal board at a construction site, and the unit set is installed in a low double floor. A wiring system that can take out the power supply and telephone outlet will be completed just by laying.

[0008]

[Action]

 In recent business offices, the layout is frequently changed due to the increase in office automation equipment, the adoption of carpet or expansion of business as a countermeasure against the noise in the office, and the fragmentation of business. Therefore, although there is a strong demand for technological innovation in flexible indoor wiring systems that can respond to these changes in offices, there is still a need for specialists in wiring construction, and there is concern that a great deal of labor and quality may cause concern. It is the current situation.

The present invention solves these problems and makes it possible to save wiring work, ensure safety, and stabilize quality. In addition, this device allows for advanced wiring and can flexibly respond to future changes in demand, so a system that facilitates wiring management can be constructed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a cross-sectional view of a cable with a branch outlet for power supply. The core 2 of the cable 1 and the branch wire 3 connected to the branch outlet 6 are connected by a crimp sleeve 4 according to an electric circuit, and the insulation sleeve 3 is placed on top of it. A cover 5 is covered to form a connecting portion. Then, the cable 1, the branch outlet 6 and the connecting portion thereof are housed in the insulating box 8, and the insulating compound 7 is filled and cured to form a cable with a branch outlet. It should be noted that the cable 1, the branching concentrator 6 and the connecting portions thereof may be integrally molded with an insulating resin.

FIG. 2 is a side view showing a unit cable with a branch outlet in which a plurality of branch receptacles 2 configured as shown in FIG. 1 are continuously provided at regular intervals on the extension of the cable 1. The unit cable with the branch outlet may be configured by connecting a plurality of the cables with the branch container shown in FIG. 1 at regular intervals.

FIG. 3 is an explanatory diagram showing a method of using the unit cable with branch outlet of FIG. One end of the cable of the unit cable 1 with a branch outlet is connected to a distribution board or a terminal board 10 provided on a wall 9 and is wired in a space 13 corresponding to a double floor portion of an under carpet 11 and a floor 12. For the power supply, the user only has to insert a commercially available table tap and twist it. For telephones, you can simply plug in a commercially available modular cord. Then, pull out the other end of the carpet to any place on the carpet and use it.

[0013]

[Effect of device]

 As described above, according to the cable with branch outlet for a double floor and the unit cable with branch outlet of the present invention, the construction can be performed easily by simply connecting one end of the cable to the distribution board or terminal board. A great deal of labor can be saved. Since it can be produced in advance, a safe and stable wiring system is possible. It is possible to respond flexibly and easily without the need for specialist work for increasing demand or changing the location of use. It can be laid in an orderly manner in the space of the low double-floor part, and wiring management is easy. No specially designed connection cord is required for use, and commercially available connection cords can be used as they are.
