Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure for a plurality of lighting devices installed on a ceiling surface of a building, for example.

[0002]

2. Description of the Related Art Conventionally, when a large number of luminaires are installed on a ceiling surface of a building, electric wiring to each luminaire is individually connected to a power cord or provided separately for each luminaire. There is a means for directly connecting a wiring cable from the branch connection part to another lighting device.

[0003]

However, the former method has a drawback that the wiring becomes complicated and maintenance is troublesome, and the latter method requires that the cable used for the wiring be made on site. In addition to the problem that work efficiency deteriorates because it must be done, both the former and the latter means peel off both ends of the cable and connect them directly, so there is a danger of electric shock when working on a live line, which is a safety issue. There is.

Therefore, in the present invention, one relay box having a male connector for receiving a power source and a male connector for branching a power source, and at the same time having a connection terminal connected to a power source section of a lighting fixture is incorporated in a casing of the lighting fixture. The main object of the present invention is to simplify the wiring of a plurality of luminaires installed and to reduce the cost, thereby solving the above-mentioned conventional problems.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, in the connection structure of the lighting device according to the present invention, the relay box 4 including the upper and lower two-stage male connectors 3 and 3 for receiving the flat female connectors 2 is provided in the casing 8 of the lighting device. The relay box 4 is equipped with conductor branch terminals 6 provided at the ends of the respective branch lines 5a of the single-phase line 5 connected to the power source section of the lighting fixture, and the branch terminals 6 are bifurcated. Two insertion pieces 6a, 6a that are branched and project into the receiving holes 3a, 3a of the upper and lower male connectors, respectively.
The structure is provided with.

[0006]

In the present invention configured as described above, as shown in FIGS. 1 and 2, the female connector of the relay cord 1 connected to the power source is connected to the male connector 3 above or below the relay box 4 of the lighting fixture A1. 2 is inserted, and the male connector 3 on the other side is inserted with the female connector 2 on the input side of another relay cord 1 (see the relay cord in the intermediate portion of FIGS. 1 and 2). Then, the female connector 2 on the output side of the relay cord is inserted into one of the upper and lower male connectors 3 of another lighting fixture A2, and the other lighting fixtures A3 ... Are sequentially connected via the relay cord and used. is there.

[0007]

Embodiments of the present invention will be described below with reference to the embodiments shown in the drawings. 1 to 4 show a first embodiment of the present invention, and reference numerals A1, A2 and A3 denote lighting fixtures. A relay box 4 is provided in each of the casings 8 of these lighting fixtures.

The relay box 4 is provided with upper and lower two-stage male connectors 3 and 3 for respectively receiving flat female connectors 2 described later. The male connectors 3 and 3 are used for power supply reception and power supply branching. A horizontally long receiving hole 3a for receiving the female connector 2 and an insertion piece 6a projecting into the receiving hole and serving as a substantial connection terminal. Formed by and.

Further, three conductor branch terminals 6 provided at the end of each branch line 5a of the single-phase line 5 connected to the power source section of the lighting fixture are incorporated in the relay box 4.
These branch terminals 6 are branched into upper and lower bifurcations and project into the receiving holes 3a and 3a of the upper and lower male connectors 3 and 3 to form the insertion pieces 6a and 6a.

Reference numeral 2 is a flat female connector formed at the end portion of the relay cord 1, and insertion holes 2a ... Are formed in a horizontal row on the front end surface thereof. This flat female connector is well known in the art, and each insertion hole 2a
Is directly connected to each branch line of the relay cord 1 formed by a single-phase line, and has a structure for receiving the plug-in piece 6a of the male connector 3 and electrically connecting it. When the flat female connector 2 is inserted into the receiving hole 3a of the relay box 4, the female connector is temporarily held at a predetermined position by engaging with a recess (not shown) formed on the side surface of the receiving hole 3a. An elastic engaging portion 7 is provided on the side surface of the connector.

In use, as shown in FIGS. 1 and 2, insert the female connector 2 of the relay cord 1 connected to the power source into one of the upper and lower male connectors 3 of the relay box 4 of the luminaire A1, The input side female connector 2 of another relay cord 1 (see the relay cord in the intermediate portion of FIGS. 1 and 2) is inserted into the other male connector 3. Then, the female connector 2 on the output side of the relay cord is inserted into one of the upper and lower male connectors 3 of another lighting fixture A2, and in the same manner, other lighting fixtures A3 ... Are sequentially connected and used via the relay cord. is there.

In the above-mentioned embodiment, the embodiment of the connection structure intended for the single-phase three-wire system is shown, but the same can be applied to the case of the single-phase single-wire system. FIG. 5 shows an embodiment thereof, in which the single-phase line 5 has two dividing lines 5a and 5a, and two branch terminals 6 are connected to each dividing line. There are also two insertion holes 2a and 2a.

Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments, and has the constitutional requirements and achieves the object of the present invention. However, it can be carried out by appropriately modifying it within a range in which the following effects are exhibited.

[0014]

As described above, according to the present invention, there is provided one relay box having a male connector for receiving power and a male connector for outputting power, and at the same time having a connection terminal connected to a power source section of a lighting fixture. Since it is built into the casing of the lighting fixture, even if many lighting fixtures are installed, each lighting can be easily wired by using the male connector for receiving the power and the male connector for branching the power of the relay box of each lighting fixture. It is possible to connect equipment, and since the relay box has a simple structure in which two or three branch terminals branched in a bifurcated shape are arranged vertically, it is easy to manufacture and can be provided at low cost. There is a remarkable effect such as.
