Furthermore, 13a and 13b are the spacing pieces 1 of the end surface 7'.
A pair of locking protrusions protruding from portions 1 equidistant from 1 are used to lock a pair of power supply printed patterns 14a and 14b for taking out the output of the inverter 2 lighting circuit incorporated in the printed circuit board 7, respectively. It is formed to extend to the protrusions 13a and 13b.

Furthermore, 15a and 15b are a pair of L-shaped socket fittings made of elastic metal plates with an abbreviated bottom shape, and base ends 16a and 16b
The upwardly bent central portion is provided with locking square holes 18a, 18b having edges 17a, 17b, and folded portions 19a, 19b are provided at the tip portion, and the free end 20
a and 20b are bent into a substantially dogleg shape to form the fluorescent tube terminal 12a.
, 12b.

21b, and the free ends 20a, 20b
Elongated holes 22a, 22b are bored at the base ends 16a, 16b of the base end 16a, 16b.

Then, by inserting the locking protrusions 13a and 13b of the printed circuit board 7 into the square locking holes 18a and 18b, respectively, with the locking steps 21a and 21b facing each other, these pair of locking steps 21a and 21b are L-shaped socket fittings 15a, 15b
is temporarily attached to the printed circuit board 7 with the spacer holding piece 11 in between, and at this time, the square holes 18a, 1ab
The bent edges 17a, 17b bite into the locking protrusions 13a, 13b and the back surface of the printed circuit board 7 to prevent removal from the printed circuit board 7.

And the base ends 16a of these pair of L-shaped socket fittings 15a, 15b.

16b to the respective power feeding printed patterns i4a, 14b of the printed circuit board 7 by soldering to form a pair of L-shaped socket fittings 15a.

15b is mechanically and firmly attached to the end surface 7' of the printed circuit board 7, and is also used as an electrical groove. They are biased toward each other until they come into contact with the notches 11.11 of 11.

23 a and 23 b are integrally molded with the right case 6 a and the left case 6 b, and cover the pair of L-shaped socket fittings 15 a and 15 b, and are a right socket cover and a left socket cover, and are connected to the left socket cover and the left socket. Fluorescent lamp terminal 1 is attached to the cover 23b.
A pair of insertion notches 25a, 25b forming the insertion openings 24 of the terminals 2a, 12b, and a pair of insertion notches 27a, 27b forming a terminal insertion opening 26 communicating with the insertion openings 24 are bored. .

Then, by inserting the pair of terminals 12a, 12b of the fluorescent lamp 8 into the terminal insertion hole 26 from the insertion hole 24 formed by the left and right socket covers 23a, 23b, and rotating the fluorescent tube 8, the pair of terminals 12a, 12b of the fluorescent lamp 8 are inserted. The terminals 12a, 12b are connected to the stepped portions 21a, 21 of the pair of L-shaped socket fittings 15a, 15b.
b.

Reference numeral 28 denotes a socket device on the other side that supplies power from the inverter type lighting circuit of the printed circuit board 7 to the other pair of terminals of the fluorescent tube 8, and has substantially the same configuration as the socket device 10.

The fluorescent lamp socket device of the present invention is as described above, and in particular, a spacing holding piece is provided on the end face of the printed circuit board, and a pair of locking protrusions are provided on the end face at a portion equidistant from the holding piece. Furthermore, a printed pattern for power supply is extended to each of these locking protrusions, and is formed into an abbreviated shape, and a square hole for locking into which the protrusion is inserted is bored at the base end, and a loose hole is formed. L with a step on the end for hanging a fluorescent lamp terminal.
Attach a pair of mold socket fittings by sandwiching the holding piece between the pair of locking protrusions so that the stepped portions of the sockets face each other, and fix the base ends of each to the respective printed patterns for power supply by soldering. Since these steps elastically support a pair of fluorescent tube terminals, the pair of L-shaped socket fittings can be mechanically attached to the end face of the printed circuit board while being positioned by the pair of locking protrusions. It is possible to simplify the manufacturing process by making it possible to have a distant relationship with the electrical installation.

Furthermore, since the fluorescent lamp socket device of the present invention has a pair of L-shaped socket fittings with a spacing piece interposed between them, the ends of these L-shaped socket fittings do not come into contact with each other. In addition, the fluorescent lamp terminal can be inserted extremely easily from the gap between the pair of free ends.

Furthermore, according to this proposal, the pair of L-shaped socket fittings are installed upright on the end surface of the printed circuit board, so the fluorescent tube is mounted at right angles to the printed circuit board, and therefore tall electrical components can be mounted on the surface of the printed circuit board. Also, fluorescent tubes can be attached regardless of the electrical components.
