Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a socket device for a single-cap fluorescent lamp used in a single-cap fluorescent lamp such as a U-shaped fluorescent lamp [prior art] ] The arc tube of the U-shaped fluorescent lamp has a pair of straight tube sections parallel to each other and a bent section connecting these straight tube sections, and a base is provided only at one end of the straight tube sections. A cap bottle is provided protruding from the end face of this base. Generally, U-shaped fluorescent lamps use standardized cap bottles such as those typified by GIOQ.

This type of cap (GIOQ type) has four cap bottles protruding in the same direction, and is widely used as a cap for annular fluorescent lamps.

Therefore, it is possible to use the annular fluorescent lamp socket for the above-mentioned U-shaped fluorescent lamp.

However, although an annular fluorescent lamp socket provides an electrical connection to the base pin, it does not have the function of holding a lamp. Therefore, in addition to the socket, additional parts such as a lamp holder were required.

On the other hand, as in the prior art lamp socket illustrated in FIG.
A socket of a special shape is also being considered, which has a hole 2 for inserting a lamp base, and a connection hole 3 for inserting a base pin at the bottom of the hole 2.

This type of socket has both the function of supporting the lamp and the function of electrically connecting the base bottle, so there is no need to use a separate lamp holder.

[Problem that the invention seeks to solve]

However, when a synthetic resin socket body having a special shape is used as described above, the mold cost for integrally molding the socket body is quite high. Also, when the lamp is inserted into the socket, most of the base is surrounded by the socket body, which causes the temperature of the base to rise.
This can sometimes be a problem.

[Means for solving problems]

In the socket device of the present invention, a socket base made of sheet metal is provided with a pair of rising pieces for sandwiching and fixing the base of a single-cap fluorescent lamp from both sides, and the socket base has a cap bottle of the lamp protruding from the socket base. A pair of socket clamping pieces are provided on both sides of the part where the lamp is inserted, and between the socket clamping pieces, there is a plug-in type lamp socket for an annular fluorescent lamp. If four people hold an equivalent lampholder between them, the result is -):,1-.

[Effect]

In the socket device having the configuration 1, the base of the gold fluorescent lamp is held by the socket base qL or 61-:2. That is, mechanical support 11) of the lamp is provided. Further, the base pin protruding from the end face of the lamp base is inserted into the connection hole of the lamp socket attached to the socket base. Cum I.

An electrical connection is made.

〔Example〕

The piece 1 gold fluorescent lamp 10 used in the embodiment shown in FIG. It is equipped with 12. The interior of the arc tube 11 is filled with mercury and a suitable rare gas, similar to a well-known fluorescent lamp, and an electrode (not shown) is provided at the end of the arc tube 11.

Then, from the end face of the base 12, four base pins 14 protrude which are electrically connected to the electrodes. This pin 14 is G IO
It is a standard product known as Q, and is the same as that used in the caps of ring-shaped fluorescent lamps. Also, base 1
A pair of convex portions 16 (only one shown) is formed on both sides of 2.

On the other hand, the socket stand 20 is press-molded from a metal plate having spring properties, and includes a flat main body 21 located at the center and a pair of legs 2 continuous to both ends of the main body 21.
2. This leg portion 22 is fixed to a substrate (not shown) or the like.

A pair of rising pieces 24 that protrude toward the lamp 10 are provided on both sides of the main body 21 .

These rising pieces 24 can be elastically bent in directions toward and away from each other like a leaf spring. At the tip of each rising piece 24, a hook portion 25 is provided which is bent into a ``1'' shape in the direction facing each other.

2. The rising piece 24 is for holding the base 12 of the lamp from both sides, and the hook is between the part 25 and the convex part 16.
The engagement with the base 12 prevents the base 12 from being removed.

Further, the main body portion 21 has an opening 27 located between each of the vertical pieces 24 for passing the cap bottle 14 therethrough. That is, when the base 12 is supported on the 1r rising piece 24, the base bottle 1 is placed on the back side of this opening 27.
4 stands out.

A pair of socket clamping pieces 30 are provided on both sides of the part from which the cap bottle 14 protrudes (at an angle of 7 degrees). Ru.

Each socket clamping piece 30 is formed with a tongue piece 31 that protrudes on opposite sides.

Then, between the socket holding pieces 30, there is a lumb socket...I to 3.
5 is held in place. This lamp socket 35 is a socket for a GIOQ base similar to the socket used for general annular fluorescent lamps, and has four connection holes 36 at predetermined intervals as shown in FIG. It is formed. Electrical contact pieces (not shown) are buried inside the connection hole 36, and these electric contact pieces are electrically connected to the cord 37.

Further, the tongue pieces 3 are provided on both left and right sides of the lamp socket 35.
A recess 40 is formed at the position where the holder 1 fits. These recesses 40 are formed in such a position that the tongue piece 31 just fits when the lamp socket 35 is inserted between the clamping pieces 30 and 30 all at once. Furthermore, a pair of protrusions 41 are provided at the edge of the opening 27 to prevent the lamp socket 35 from shifting.

The above (1+4 configuration socket device is the lamp socket 35
When the lamp socket 35 is held between the clamping pieces 30, the tongue piece 31 fits into the four parts 40 and is prevented from slipping by the protrusion 41, so that the lamp socket 35 is firmly held.

In this state, when the lamp base 12 is inserted between the upright pieces 24, the hook portion 25 engages the convex portion 16, and the base bottle 14 is inserted into the connection hole 35 of the lamp socket 35.
to fit. In this way, the electrical connection is made and the base 12 is held on the socket stand 20. Therefore,
No separate lamp holder is required.

According to the socket device having the structure described in item 1, the socket base 20 is obtained by press-molding a single plate with spring properties, so there is no need for expensive molds used for integrally molded synthetic resin products. be. Moreover, the lamp socket 35 used in this embodiment only needs to be provided with four parts in an existing annular fluorescent lamp socket.

Furthermore, since most of the base 12 of the socket stand 20 is exposed when the lamp 10 is inserted, heat dissipation is good during lighting.

In the above embodiment, the tongue piece 31 is fitted into the recess 40 to prevent the lamp socket 35 from being pulled out. The lamp socket 35 may be bent and provided with locking portions, and the lamp socket 35 may be held in a hug manner by these locking portions.

If such a structure is adopted, the recess 40 becomes unnecessary, so that it is possible to use exactly the same socket as the existing annular fluorescent lamp socket.

Further, the socket device of the present invention can be similarly used for curved tube-shaped fluorescent lamps other than the U-shape.

〔Effect of the invention〕

According to the present invention, the socket can be provided at a lower cost than the conventional special-shaped socket using an integrally molded synthetic resin product, and has better heat dissipation.
