Description

Description: TECHNICAL FIELD The present invention relates to an underfloor wiring system in which a surface floor is provided on a base floor via a space, and a track is wired through the space.

[Background Art] In recent years, with the increase of office automation equipment and the like, so-called wiring flooding has become a problem. In order to solve such a problem, underfloor wiring of a double floor structure such as a free access floor has been proposed. By using the system,
2. Description of the Related Art Wiring a track in a space in a floor is performed.

By the way, such underfloor wiring systems have a high degree of freedom in wiring. Therefore, when the wiring of office automation equipment or the like is changed, a power supply line (commercial power supply line) or an information line (LAN line, It is possible to improve the usability by simultaneously changing the arrangement of wiring devices such as outlets for connecting the telephone line). However, conventionally, as shown in FIG. 3, since the lines 12 to 14 housed under the floor are directly connected to wiring equipment such as the outlet 7, a joint box is provided in the middle of the lines 12 to 14. Even if 11 is installed, the length of the tracks 12 to 14 becomes longer, and the entire floor is required only by changing the layout of the wiring equipment. There was a problem that it was necessary to ask a contractor.

[Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to provide a connector provided in the middle of a line even when the arrangement of wiring devices is changed. It is an object of the present invention to provide an underfloor wiring system in which wiring can be easily changed only by attaching and detaching.

[Disclosure of the Invention] (Configuration) The underfloor wiring system according to the present invention includes a base floor, a surface floor provided on the base floor via a space, an outlet wired through the space and arranged on the surface floor, and the like. A line leading to the connecting device, a joint box having a plurality of quick connection terminals for detachably connecting the line and interposed in the middle of the line, and in the middle of the line between the joint box and the connecting device. A first connector provided, and a second connector detachably connected to the first connector and connected to a connecting device via a line, wherein the first and second connectors lock between the two connectors. The wiring mechanism can be easily changed only by attaching and detaching the connector.

(Embodiment) As shown in FIG. 1, a support 2 is arranged at an appropriate position on a base floor 1, and a surface floor 3 composed of a plurality of floor boards 3a is provided on the support 2.
Is placed. Thereby, a space corresponding to the height of the support 2 is formed between the base floor 1 and the surface floor 3. This type of floor structure is commonly known as a raised floor. A joint box 11 is fixed at an appropriate position on the foundation floor 1 so that the service line 12 is branched into three. The joint box 11 is, as shown in FIG.
The branch line 12 and the branch line 13 are respectively connected to the terminals of the quick connection terminal structure. That is, the joint box 11 is provided with four release buttons 15 and a confirmation window 16 corresponding to each release button 15, and terminal portions corresponding to each release button 15 are electrically connected to each other internally. Configuration. The confirmation window 16 can confirm whether the lead-in line 12 or the branch line 13 is securely connected to the terminal corresponding to each release button 15. A female connector 5 is provided at a tip end of the branch line 13, and a connection line 14 is connected to a male connector 6 which is detachably connected to the female connector 5. At the other end of the connection line 14, an outlet 7 which is appropriately fixed to the floor plate 3a and whose upper surface side can expose a blade insertion port is provided as a connection device. As shown in FIG. 2, the female connector 5 has locking claw pieces 21 on both side surfaces. By joining, the female connector 5 and the male connector 6 are connected with high mechanical strength in a state of being connected. Since the locking claw pieces 21 are pressed from both sides of the female connector 5, the engagement state with the locking projections 22 can be easily released.
The female connector 5 and the male connector 6 can be easily separated.

With the above configuration, when the arrangement of the outlet 7 is changed, the outlet 7 is arranged at a desired position in a state where the female connector 5 and the male connector 6 are separated from each other. Can be connected to the female connector 5 disposed in the outlet, so that the layout change of the outlet 7 can be easily performed even by an amateur. In the above-described embodiment, the outlet 7 is fixed to the floor plate 3a. However, as shown in FIG. 2, a table tap 7a not fixed to the floor plate 3a may be used. Since such a table tap 7a can be freely arranged, it can be pulled out from the floor plate 3a in the immediate vicinity of the equipment after the arrangement of the office automation equipment or the like is determined, and it is not necessary to route the track, and the exposure of the wiring is minimized. It can be limited to the limit. Among the female connectors 5 connected to the branch line 13 branched by the joint box 11, those having no male connector 6 to be connected are:
It is desirable to close the connection portion with the lid plate 23 also from the viewpoint of dustproofing. Further, the drop-in line 12 and the branch line 13 may be held by using a cord clip 24 so as not to be separated. Further, in the above-described embodiment, the power supply line is shown as the line, but it goes without saying that a signal line (a small power line such as a telephone line or a data communication line) can have the same configuration.

[Effects of the Invention] As described above, the present invention relates to a base floor, a surface floor provided on the base floor via a space, and a connection device such as an outlet wired through the space and arranged on the surface floor. To the line, a joint box having a plurality of quick connection terminals for detachably connecting the line and interposed in the middle of the line, and a joint box provided in the middle of the line between the joint box and the connecting device. A first connector, and a second connector detachably connected to the first connector and connected to the connection device via a line, wherein the first and second connectors lock a lock mechanism between the two connectors. Since the wiring can be changed by attaching / detaching the connector, the distance in which the line is routed is shortened, and there is an advantage that the arrangement of the connecting device can be easily changed. In addition, the first connector and the second connector have a lock mechanism for locking between the two connectors, so that a mechanically high coupling strength can be obtained in a state where the first connector and the second connector are connected. And
A reliable connection can be made. In other words, even when the arrangement of the connecting devices is changed, the work only in the vicinity of the changed portion need be performed without the need for extensive construction work, so that even a layman can perform the work relatively easily.
