When removing the dustproof cover 16, the claw 17 engaged with the window hole 19 of the outer shell 14 may be pushed down by the tip of a screwdriver, and the dustproof cover 16 may be pulled out in the direction opposite to the arrow B.

One end of the upper plate of the outer shell 14 is extended from the lower plate to form a fixing piece 21 at its tip, and a fixing hole 22 corresponding to the fixing hole 9 of the housing 3 is formed in the fixing piece 21. A locking projection 33 that is engaged with the locking hole 32 is provided so as to project upward. In addition, as shown in FIG. 3, a light bulb socket support plate 23 is fixed to the lower surface of the upper plate of the outer shell 14 by screws 25, and the light bulb socket 24 is attached to the light bulb socket support plate 23.
Is installed. The light bulb socket 24 is mounted so as to incline downward on the tip side so that the tip thereof projects from the lower plate of the outer shell 14.

At the other end of the outer shell 14, a connecting terminal 26 composed of a quick-connect terminal is attached below the notch 15, and a socket cord 27 is soldered to the connecting terminal 26.
This soldering work is performed through the notch 15. Also,
A terminal cover 28 is covered on the upper surface of the connecting terminal 26.

On the upper surface of the other end of the outer shell 14, the connecting terminal 2 is provided.
A recess 29 is formed below 6 and a power cord insertion port 30 that communicates the outside of the outer shell 14 with the recess 29 is formed at a position facing the cut portion 18 of the dust cover 16. Also,
A spring 34 whose position movement is restricted is housed inside the recess 29. The end of the spring 34 on the power cord insertion port 30 side is
It is inclined upward in one direction along the insertion direction of the power cord 20 and is normally urged so that its tip comes into contact with the connecting terminal 26.

Further, a release button 31 is vertically movably inserted into the terminal cover 28 at a position facing the tip of the spring 34. At the lower end of the release button 31, a portion where the power cord insertion port 30 is not formed protrudes like a comb. And, the lower end thereof is normally located above the connecting terminal 26, but when the release button 31 is pushed, the lower end is lowered,
The protruding portion at the lower end passes through the connecting terminal 26 and the spring 34
The tip of the spring is pushed down, and the spring 34 is separated from the connecting terminal 26.

The housing 3 and the supporting portion 4 are assembled as follows. First, the housing 3 is assembled by stacking the housing body 5, the frame 6 and the reflection plate 7. Then
As shown in FIG. 1, one end of the preset support portion 4 is inserted in the direction of arrow A through the bulb insertion opening 8 and the internal insertion opening 11, and the fixing piece 21 of the support portion 4 is reflected from the top surface of the housing body 5. Insert it between the top surface of the plate 7.

Locking protrusion 3 protruding from the upper surface of the fixing piece 21
Since the housing 3 and the supporting portion 4 are positioned when the locking hole 32 of the housing 3 is engaged with the housing 3, the fixing hole 9 of the housing body 5 and the fixing hole 22 of the supporting portion 4 are provided as shown in FIG. Further, the screws 25 'are inserted into the mounting holes 13 of the reflection plate 7 to assemble the housing 3 and the support portion 4. In addition,
The screw 25 ′ may be inserted through the fixing hole 9, the fastening hole 22 and a part of the mounting hole 13 depending on the model.

To connect the power cord 20 and the socket cord 27, as shown in FIG. 6, the power cord insertion port 30 of the support portion 4 is inserted through the notch portion 18 of the dustproof cover 16.
Insert the power cord 20 into the. Then the power cord 20
While pushing down the inclined end portion of the spring 34, the tip end of the spring enters the inside of the support portion 4, and the power cord 20 is pressed against the connecting terminal 26 by the urging force of the spring 34 to be connected.

When disconnecting the power cord 20, the release button 31 may be pressed to push down the end of the spring 34, the spring 34 may be separated from the connecting terminal 26, and the power cord 20 may be pulled out.

The electric lamp mounting device 1 is mounted on a supporting surface such as the ceiling 37 as follows. As shown in FIG. 7, a fitting hole 38 for embedding which is slightly smaller in diameter than the upper flange 10 is bored in the ceiling 37, and the electric lamp mounting device 1 is tilted so that the fitting hole 38 is inserted into the fitting hole 38 from the tip of the support portion 4 by an arrow C Insert along.

Next, when the housing 3 is pushed up, the projecting fins 36 are pressed against the ceiling 37, the pressing spring 35 is pushed into the housing 3, and the portion above the upper flange 10 of the housing 3 is smoothly fitted. Aperture 3
8 is inserted.

When the pressing spring 35 passes through the fitting hole 38, the pressing spring 35 projects again to the outside of the housing 3, and as a result, as shown in FIG.
