DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Reference numerals 1 and 2 denote a pair of lighting fixtures, which are box-shaped with an open lower surface and have a rectangular shape, to which a socket for mounting a lamp (not shown) is attached, and which are attached to a ceiling or the like for use. The instrument main bodies 1 and 2 are formed by bending the top edges 3, 4 and the side surfaces 5, 6 and the lower edges of the open side in a horizontal direction outward and bending the tip edges of the frame edges 9, 10 upward. Then, the end plates 11 and 12 are provided. The end plates 11 and 12 form the end faces on the respective sides of the instrument bodies 1 and 2. Further, the instrument body is attached to the ceiling or the like by a pipe 13 fixed in the longitudinal direction of the upper surface. A roundout is formed at the center of the side surfaces 5 and 6, and a part of the knockout portion 14 is connected to the side surfaces 5 and 6. This knockout part 14
Is removed when the connector 15 to be described later is attached to the instrument main bodies 1 and 2, and an insertion hole 16 for inserting the connector 15 is formed. The knockout portion 14 is formed so as to correspond to the side surfaces 5 and 6 between the instrument bodies that connect the instrument bodies.
Further, if the knockout portion 14 is used as it is, it can be used for a lighting fixture that does not have a connection structure.

Reference numeral 15 is a connecting member made of an elastic synthetic resin having a hollow circular cross section. The hollow circular hole is a power supply line through hole 17 for inserting a power supply line, and has a size such that the power supply line can be inserted therein. A circular flange portion 2 is provided at one end of the connector 15.
0 is provided, and the diameter of the flange portion 20 is larger than the diameter of the knockout portion 14. Three stoppers 18 are provided on the outer periphery of the other end, and a tip end of each stopper 18 is formed with an inclined surface 19 in the insertion direction so as to facilitate insertion. Further, a notch 7 is provided between the stoppers 18 so that the stoppers 18 are easily deformed in the radial direction.
To provide. The dimension A between the flange portion 20 and the stopper portion 18 is formed to be substantially the same as the separation dimension B between the instrument body 1 and the instrument body 2.

Next, an operation of connecting the pair of instrument bodies 1 and 2 will be described. The knockout portion 14 formed on the side surfaces 5 and 6 of the instrument bodies 1 and 2 is removed to form the insertion hole 16.
Next, the appliance main bodies 1 and 2 are attached to the ceiling or the like with the side surfaces 5 and 6 having the insertion holes 16 facing each other. Next, the tool bodies 1 and 2 are fixed by the connector 15. First, when the stopper 18 of the connector 15 is first inserted into the insertion hole 16 of the device body 1 from the inside of the device body 1, the connector 1
The tip end inclined surface 19 of the stopper 18 provided on the outer periphery of 5 contacts the outer peripheral surface of the insertion hole 16, and the stopper 18 is inserted while being deformed radially inward. Through the connector 15, and then the tip end inclined surface 19 of the stopper 18 is inserted into the insertion hole 16 of the instrument body 2.
When the stopper 1 hits and passes through the insertion hole 16,
8 spreads in the radial direction, and abuts and fixes the inside of the insertion hole 16 of the instrument body 2. Between the back surface of the side surface 5 of the device body 1 and the back surface of the side surface 6 of the device body 2, the flange portion 20 of the connector 15 and the back surface of the stopper 18 contact and elastically fix.

However, since the A dimension of the connector 15 is made of synthetic resin, there is almost no variation in the dimension. However, since the instrument main bodies 1 and 2 are made of sheet metal, the dimension B has variation. The flange 20 of the tool 15 and the back surface of the stopper 18 may come into contact with each other and may not be elastically fixed. At that time, a spacer 21 having a disk shape and a shape in which the stopper 18 is released may be inserted into the connector 15 for adjustment. In addition, a convex portion 22 having a different height may be provided at a position corresponding to the stopper 18 of the connector 15 on the side surface of the instrument body for adjustment. Next, after inserting the power supply line 23 wired in one instrument body into the power supply line through hole 17 formed in the coupling tool 15 and passing it through the other instrument body, the power supply line wired in this instrument body Connect with or wire within the body of the device. In addition,
The power line 23 is connected to a ballast of the instrument body and the like, and is further connected to a commercial power source. A code extending from a ballast (not shown) or the like is connected. Although the outer shape of the connector 15 has a round cross section, it may have any shape such as a triangle or a quadrangle as long as the through hole into which the power supply line can be inserted is formed.

According to the connecting structure of the luminaire thus constructed, the connecting tool 15 for connecting the luminaire body 1 and the luminaire body 2 is made of synthetic resin, and is between the luminaire body 1 and the luminaire body 2. Since the power supply wire 23 disposed in the connector is inserted into the wire through hole 17 provided in the connector 15, it does not hit the edge of the wire through hole opened in the sheet metal and does not damage the coating of the power supply wire. Since 15 is made of synthetic resin, it is insulated and protected. To connect and fix the tool bodies 1 and 2, after fixing the tool bodies 1 and 2 to the ceiling or the like, the connector 15 is simply inserted into the insertion hole provided on the side surface of the tool body from the inside of the tool body. Since it can be fixed only by itself, other fasteners such as screws are not required, the structure is simple, and it can be easily attached without any trouble. Furthermore, the instrument main body 1,2
Even when wiring the power supply line between them, there is no need to cover the power supply line with a fixture after the power supply line wired in the equipment is exposed outside the body of the equipment. By simply inserting the power supply line into the formed power supply through hole, the power supply line for the feed between the device bodies can be wired, so that the wiring work can be performed easily. Further, since the connector is made of synthetic resin having plasticity, the flange portion 20 and the stopper 18 are
And can elastically lock the body of the device. For this reason, elastic forces are exerted on both end surfaces of the device main body so that the devices are connected and fixed without any gap or deviation.

[0012]

Since the present invention is constructed as described above, the connection between the tool bodies can be easily fixed by simply inserting the connector into the insertion hole on the side surface of the tool. Furthermore, in order to send the power line wired in the instrument body to other instrument bodies and wire it,
Wiring can be performed simply by passing the feed power line through the power line through hole formed in the connector. Moreover, the power line is not exposed to the outside of the instrument body. Since the connector is made of synthetic resin, the insulation of the feed power source wire is improved at the same time as the coating is protected. Since the connector is made of elastic synthetic resin, it has an effect that it can be reliably and easily connected so that there is no gap or gap between the instrument main bodies.
