DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device suitable for wiring under floors of intelligent buildings and the like.

[0002]

2. Description of the Related Art In recent years, with the spread of OA equipment, intelligent buildings have been constructed in various places where a wiring space for power supply is secured under the floor in accordance with the installation layout of the OA equipment. In this kind of intelligent building,
In order to place tap outlets near the place where OA equipment is installed, wiring devices for power distribution are fixed in advance at various places under the floor, and plugs of tap outlets can be connected to appropriate wiring devices as needed. ing.

[0003] A conventional wiring apparatus used for wiring under the floor of an intelligent building is disclosed in JP-A-6-529.
No. 34, No. 52945, No. 52946, No. 52947, No. 52948, No. 52
949 and 52950, JP-A-8-317
No. 532 and the like.

The wiring devices disclosed in these publications each have a unique connection portion for connecting a special plug having a plug blade in a recess called a harness plug. The connecting portion is formed in a convex shape, and has a built-in blade receiving terminal. The harness plug is firmly connected by fitting the concave portion to the peripheral wall of the connection portion, and the plug blade is electrically connected to the blade receiving member in the connection portion.

[0005]

The above-described conventional wiring device can maintain a strong connection state of the harness plug and has high reliability. However, since the harness plug has a special shape, the manufacturing cost is high, and the demand for the harness plug is small. Therefore, the number of electric retail stores handling tap outlets with the harness plug is extremely small.

On the other hand, recent intelligent buildings are designed so that wiring under the floor can be changed easily by opening the floor, and users can handle wiring devices under the floor with the same ease as ordinary wall outlets. It is becoming possible. Also, with the addition of OA equipment, there have been many requests that users want to purchase tap outlets themselves and connect them to wiring devices.

[0007] The present invention has been made in view of such circumstances, and has as its object to provide a wiring device that can also connect a general-purpose plug provided in a normal tap outlet.

[0008]

To achieve the above object, a wiring apparatus according to the present invention comprises a wire connecting portion for inserting and fixing a wiring cable, and a general-purpose plug for inserting a general-purpose plug with a protruding blade. A connection portion and a harness plug connection portion for fitting and fixing a harness plug having a plug blade in a concave portion are provided in the device main body, and terminals provided inside the power supply connection portion and provided inside the general-purpose insertion plug connection portion. The blade receiving terminal and the harness blade receiving terminal provided inside the harness plug connection portion are configured to be electrically conducted inside the apparatus main body.

According to the wiring device of the present invention, since the general-purpose insertion plug connection portion is provided in addition to the harness plug connection portion, not only the harness plug but also the general-purpose insertion plug provided in a normal tap outlet is connected. It is possible to realize various wiring forms according to the user's request.

Of course, the harness plug connection is indispensable for basic branch wiring such as connection between wiring devices. For example, if the wiring device is fixed to the user's desk side or the like and connected to an existing wiring device installed under the floor, behind the ceiling, in the wall, etc., a highly reliable branch connection via the harness plug connection part Is preferred.

Further, by forming the electric wire connection portion on both side surfaces of the device main body, forming the general-purpose plug connection portion on the front surface, and forming the harness plug connection portion on the back surface of the device main body, the electric wire connection portion can be formed. If the insertion direction of the insertion plug into the general-purpose insertion plug connection part and the fitting direction of the harness plug into the harness plug connection part are set to be substantially perpendicular to the cable insertion direction, the peripheral surface of the device body can be used effectively. As a result, each connecting portion can be formed, and the size can be reduced.

Further, by forming a connection confirmation window in the apparatus main body that allows the cable inserted into the wire connection portion to be visually recognized from the outside, a highly reliable wire connection state can be ensured.

Further, the wiring apparatus of the present invention may include a plug connection unit extension unit or a line connection unit having the following configuration according to the application. (A) A harness plug portion having a concave portion that can be fitted to the harness plug connection portion, a general-purpose plug extension connection portion into which a general-purpose plug plug protruding from the blade can be formed, and the harness plug is formed. Plug connection unit that electrically connects the plug blade provided in the recess of the part and the blade receiving terminal provided inside the additional insertion plug connection part

(B) A connecting portion having a concave portion that can be fitted to the harness plug connecting portion, a modular outlet portion for connecting a modular jack, and an electrical connection with the modular outlet portion and connection of an ISDN line cable. Line connection unit including cable terminals

[0015] By fitting the plug connection portion extension unit into the harness plug connection portion of the apparatus main body, the number of connection portions into which a general-purpose insertion plug can be inserted can be increased. In addition, it is possible to easily secure the power supply of the OA device without performing a major wiring layout change operation.

In recent years, with the spread of communication equipment for ISDN lines, there has been an increasing demand for installing modular outlets for ISDN lines in various places in a room. However, the above-mentioned line connection unit is fitted to a harness plug connection portion of the apparatus body. By combining them, the function of a modular outlet can be added, and it is possible to appropriately cope with a user request regarding an ISDN line. In addition, in the addition of the line connection unit, the harness plug connection portion functions only as fixing means of the unit, and does not have a configuration for electrically connecting the other connection portion to the modular outlet portion.
