Description

Description: TECHNICAL FIELD The present invention relates to a wiring system for supplying power to OA devices and the like in offices.

[Background technology]

Conventionally, in order to supply power to various office automation equipment such as computers and faxcimilis installed in offices, it has been common to lay a wiring cord on the floor of the office using a table tap or extension cord. ing. However, if you do this kind of wiring, hook the wiring cord and disconnect the plug,
There is a risk that data in the memory of the computer will be lost, and if the wiring cords are laid on the floor in this way, the aesthetics of the office will be significantly impaired.

[Object of the Invention] The present invention has been made in view of the above points,
An object of the present invention is to provide a wiring system in which wiring can be easily performed by inserting and removing a plug, and there is little risk of catching a foot on a wiring cord, and the appearance is not damaged. It is a thing.

[Disclosure of Invention]

The structure of the present invention will be described below with reference to illustrated embodiments. As shown in FIGS. 1 to 8, a power supply having a power plug (1) at one end and a connector body (2) for power supply at the other end. A branch cord (5) having a cord (3), a cap (4) for receiving power and a plurality of connector bodies (2), and an outlet in which the cap (4) and the connector (2) are connected to an outlet box (6). The cord (7) and the connector (8) are detachably coupled inside the hollow skirting caseway (11) that can be arranged along the lower end of the partition panel (8). Wire the body (2) by connecting them properly to each other, and place the outlet box (6) on the outer surface of the caseway (11).
The power cord (3) with the power plug (1) exposed.
Is pulled out of the caseway (11). FIG. 1 shows an example of a mounting state of office furniture. In the figure, (8) is a partition panel for office, which partitions the space inside the office into appropriate work spaces. A workbench (9) is installed on the partition panel (8), and an OA device such as an office computer (10) is installed on the upper surface of the workbench (9).
A hollow skirting caseway (11) is provided at the lower end of the partition panel (8).
A wiring system as shown in FIG. 2 is housed inside. As shown in Fig. 3, this wiring system includes a power cord (3), a branch cord (5), an outlet cord (7),
And an extension cord (12) and the like, which are configured by appropriately combining these. The power cord (3) has a power plug (1) at one end and a power supply connector body (2) at the other end. The branch code (5) is provided with a cap (4) for receiving power and a connector body for supplying a plurality of power.
(2) and, the code is branched at the joint box (13). FIG. 4 shows the external appearance of the connector body (2), the cap (4) and the joint box (13). As shown in the figure, both the connector body (2) and the cap (4) have a structure in which the charging part is not directly touched by the hands to prevent the risk of electric shock.
The connector body (2) is provided with three plug blades (14) for connection, and the cap (4) has the above connector body (2).
Three terminal holes (15) corresponding to each blade (14) are provided. Of these plug blades (14) and terminal holes (15), 2
One is for power supply and the other one is for ground. (16)
Is a retaining piece for the connection part, which holds the connector body (2) when the blade (14) and the terminal hole (15) are connected.
It engages with (17) to prevent the connection portion from being easily disengaged. In the present embodiment, by providing the connecting portion retaining piece (16), it is possible to prevent the connecting portion from being accidentally pulled out, and to prevent the inconvenience that the memory contents of the computer in use are erased. Is what you are doing. The joint box (13) is provided with a cord drawing hole (18). The connector body (2), the cap (4), the joint box (13) and the like are assembled by using a fixing member (19) such as a screw or a crimping tack. FIG. 5 shows the structure of a conventional joint box (13).
In this conventional example, the A dimension of the joint box (13) is as large as about 72 mm and the wiring inside the case way (11) is not easy, but in the present embodiment, the joint box (13) is The A dimension of 13) is reduced by about 37 mm to facilitate wiring inside the caseway (11). FIG. 6 shows a branch structure in the 3-branch type branch code (5). The structure shown in the figure has one power receiving cap (4) and three power feeding connector bodies (2). The cord is branched in the joint box (13). There is. In FIG. 6, reference numeral (20) is a cord tension removing portion, which prevents the tension applied to the cord (5) from being transmitted to the wire connecting portions inside the cap (4), the connector body (2) and the like. FIG. 7 shows a case where electrical wiring is performed using such a three-branch type branch code (5). In FIG. 7, (21) shows the wiring space in the caseway (11). In the system of FIG. 7, as the cord (7) with an outlet, one having an outlet box (6a) with a ground terminal as shown in FIG. 3 and one having a hook type outlet box (6b). Are used together. Figure 8 shows the cord with outlet (7)
The sectional structure of the outlet box (6) in FIG. As shown in the figure, the outlet box (6) consists of a cover block (22) and a base block (23),
The outlet block (24) is screwed into the cover block (23).
It is fixed by (25) and washer (26). FIG. 9 shows another example of the outlet box (6). In this example, the outlet box (6) is directly connected to the connector body (2).
And the cap (4) is attached. Incidentally, as shown in FIG. 3, the outlet box (6a) in the cord (7) with an outlet may be provided with a function as a joint box (13) and used as a branch cord (5). FIG. 10 shows another example of the three-branch type branch cord (5). For this branch cord (5), one connector body (2) is provided and three caps (4) are provided. Then, each of them is branched and connected through the joint box (13). The cord crimp section is located inside the joint box (13).
(27) and a tension removing section (20) are provided. The cord crimping portion (27) connects the pair of power supply lines and one ground line in each cord. Further, the tension removing section (20) is designed to remove the tension applied to the cords by pressing the ends of the cords as described above. Figure 10
(b) shows the side surface shape of the joint box (13), and as shown in the figure, the joint box (13) is formed by combining a pair of resin casings.

〔The invention's effect〕

The present invention is configured as described above, a power cord having a power plug at one end and a connector body for power feeding at the other end, and a branch cord having a cap for receiving power and a plurality of connector bodies, Inside the hollow skirting case way, where the cap and connector body connected to the outlet box are connected along the lower end of the partition panel, the cap and connector body are detachably connected. , By connecting the connection part retaining pieces provided on both sides of the cap to each other in a state of being engaged with the hooking part of the connector body, and exposing the outlet box on the outer surface of the case way, Since the power plug of the power cord is pulled out of the case way, it is easy to insert and remove the plug. Wiring can be done, and even when changing the layout inside the office or adding equipment, the electric wiring can be easily changed or added, and the wiring cord is attached to the lower end of the partition panel. Since it is housed in a hollow skirting caseway that can be placed alongside it, there is no need to remove the plug by hooking the cord on the cord unlike the conventional wiring system. The risk of losing data on the memory of a computer or the like can be reduced, and since the cord is not laid on the floor, it has the effect of significantly improving the appearance, and is also removable. The cap and the connector body to be coupled to each other are coupled to each other in a state in which the connection portion retaining pieces provided on both side surfaces of the cap are engaged with the hook portions of the connector body. In, it has the advantage to not come off facilitates the bond between the cap and the connector body, it is possible to prevent the connection portion comes off Te Ayamatsu.
