Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a round fluorescent light fixture, and is intended to improve assembly workability.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a resin housing with a parts storage chamber 2 formed on the upper surface, and has a flange 5 on which the central window edge 4 of the top plate 3 is placed, and a round hole is formed on the lower surface of the flange. A supporter 7 for the type fluorescent lamps 6, 6 is attached.

In the embodiment, a case is shown in which the top plate 3 and the shade 8 are formed integrally, but the top plate and the shade may be formed separately, or the top plate 3 and the housing 1 may be formed integrally.

Reference numeral 9 is a metal lid body for covering the parts storage chamber 2, and a pair of stabilizers 10 and 10 are juxtaposed on the underside of the metal lid body and fixed by appropriate known means, as shown in FIGS. 2 and 3. An insertion hole 11 and a mounting hole 12 communicating with the insertion hole are bored in the lid 9 between the pair of stabilizers.

Next, in FIG. 2, reference numeral 13 is a support plate made of resin, and a flashing switch 14 is attached to the center, and left and right arm pieces 15 projecting from the center by being stepped from the center in the left and right direction above the center. A night light socket 16 and lighting tube sockets t-17, 17 are attached to 15.

Incidentally, a blinking switch may be integrally formed on the support body 13.

An AC plug 18 and a fluorescent light socket 19, 19 are connected in advance to this support 13, and a pair of ballasts 10
．． It is attached to the lid body 9 between 10 and 10.

In this case, first insert the AC plug 18 through the insertion hole 11 into the lid 9.
The AC cord 20 is moved to the mounting hole 12 and attached to the mounting hole using the bushing 21.

Thereafter, as shown in FIG. 4, the insertion hole 11 is blocked by the central lower surface 22 of the support body 13, and the central lower surface is screwed with the screw 2 so that the lower surface of one arm piece 15 is located above the mounting hole 12.
Fix at step 3.

25 is Natsu.

Reference numeral 26 is a raised piece provided on the lid 9, which comes into contact with the support 13 to prevent the support from rotating.

In the conventional device, after the support 13 is attached to the lid 9, the AC cord 20 with the AC plug 18 attached is inserted through the through hole of the lid 9, and the flashing switch 14 and the ballast 1 are connected.
0, the soldering to the flashing switch 14 in particular had to be done in a narrow space between it and the ballast 10, making it difficult to work and inspecting the connection. The disadvantage was that it had to be made longer than necessary.

The present invention has been devised in view of the above points, and an insertion hole for an AC plug and a mounting hole to be inserted into the insertion hole are bored in the lid body between the mounting positions of a pair of ballasts, and the mounting hole is The AC cord is attached to the left and right arms using bushings, and the sockets for the night light and lighting tube are installed on the left and right arms, and the insertion hole is blocked by the lower center surface of the support plate, which has a flashing switch in the center. Since the bottom surface is positioned above this mounting hole, the AC cord can be connected to the flashing switch in advance, making soldering work easier and inspection easier, and the AC cord is not required. There is no need to make it longer.

In addition, since the insertion hole is directly shielded by the lower center surface of the support plate, there is no risk of the insertion hole touching the live parts on the support plate.Furthermore, since the arm piece is located above the mounting hole, even if the bushing becomes loose, etc. Even if the bushing comes off from the mounting hole and attempts to enter the parts storage chamber, or the AC cord itself attempts to enter the parts storage chamber, the bushing or AC cord will hit the underside of this arm piece, preventing further entry. Therefore, it is possible to provide a highly safe round fluorescent light fixture in which the AC cord and bushing do not accumulate in the parts storage chamber, and the AC cord does not become disconnected from the flashing switch due to the force of this insertion. .
