Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the improvement of a fluorescent lamp socket for two lamps.
In particular, the present invention relates to an assembly of a fluorescent lamp socket, easy maintenance and inspection of the inside of a fluorescent lamp fixture, and a simple structure for wiring the fluorescent lamp fixture.

[Conventional technology and its problems]

In conventional fluorescent lighting equipment, a two-light fluorescent lamp socket 2 as shown in FIG. 6 is incorporated into the equipment main body 1 with the structure shown in the same figure. The structure shown in the figure supports a socket 2 on both sides of a long appliance body 1, which has lamp pin supports at both ends and a glow lamp socket 3 in the center, and also has a reflector plate on the appliance body 1. 4 and socket 2,
A long fluorescent lamp 5 is installed between the fluorescent lamps 5 and 5, and a glow lamp 3 is installed in the glow lamp socket between the fluorescent lamps 5 from the axial direction of the fluorescent lamp.

However, according to the fluorescent lamp socket for two lamps, the lead wires are generally connected from the power source to the sockets at both ends by soldering. By incorporating quick connection terminals into the sockets at both ends, 2 is constructed.
The disadvantage is that the lamp socket as a whole becomes large, making it difficult to incorporate it into the main body of a fluorescent lamp lighting fixture.

Also, the glow lamp is between fluorescent lamps 5 and 5.
Since it is attached so that it protrudes about 20 mm from the outer end of the socket, when installing fluorescent lighting equipment or performing internal maintenance inspections, the reflector plate 4 cannot be attached or detached unless the glow lamp 3 is removed, resulting in laborious work. Moreover, during such work, small parts such as the glow lamp and the screws for attaching and detaching the reflector are likely to fall off.

Furthermore, since the glow lamp 3 is installed horizontally in the axial direction of the fluorescent lamp 5, the tip of the glow lamp 3 hangs down due to its own weight, which tends to cause contact failure between the glow lamp 3 and the glow lamp socket. be.

[Purpose of invention]

The present invention has been devised in view of the above points, and allows for easy assembly of fluorescent lamp sockets and maintenance and inspection of the interior of fluorescent lamp fixtures, as well as easy wiring of fluorescent lamp fixtures. The purpose is to provide a fluorescent lamp socket for two lamps.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 5. In the figure, 11 is a long instrument main body, 12
13 is a reflector supported on the device body 11, 13 is a socket supported on both ends of the device body 11, and 14 is a straight tube fluorescent lamp installed between the sockets 13 supported on both ends of the device body 11.

Next, the socket 1 supported at both ends of the device body 11
3 will be explained in detail with reference to FIGS. 2 to 5.
In the figure, reference numeral 15 denotes a socket body, and 16 denotes fluorescent lamp support parts provided at both ends of the socket body 15, which are configured such that a support plate 18 having a lamp insertion hole 17 is pressed forward by a spring 19. .
Reference numeral 20 denotes a quick connection block fitted into a space 21 between the fluorescent lamp support part 16 at one end and the fluorescent lamp support part 16 at the other end, and which connects a lead wire 22 inside the socket and a lead wire 23 from the outside. It is configured to press and support.

Reference numeral 24 denotes a glow lamp socket fitted into the inner end of the quick connect block 20, and is configured to be perpendicular to the tube axis direction of the fluorescent lamp.

A cover 25 is constructed to cover the socket main body 15, the quick connection block 20, and the glow lamp socket 24. Reference numeral 26 denotes a glow lamp attached to the glow lamp socket 24, and the tip thereof is configured to be located at the same level as the outer end of the socket body 15 or inside the outer end.

[Effect of invention]

In the two-lamp fluorescent lamp socket having the above structure, the quick-connect block 20 is fitted between the fluorescent lamp support part 16 at one end of the socket body 15 and the fluorescent lamp support part 16 at the other end, and the quick-connect block 20 and the fluorescent lamp are connected together. Connect the support part 16 with the lead wire 22 and fit the glow lamp socket 24 into the inner end of the quick connect block 20. Next, connect the socket body 15, quick connect block 20, and glow lamp socket 24 with the cover 25. cover.

After this, the two fluorescent lamp sockets are assembled into the fluorescent lamp fixture main body 11, and the straight tube type fluorescent lamp 14 is installed between the sockets 13.

[Effect of idea]

As described above, the present invention provides fluorescent lamp support parts at both ends of the socket body, fits a quick-connection block into the space between the fluorescent lamp support parts, and also provides a glow lamp socket at the inner end of the quick-connection block. ,
The fluorescent lamp is fitted into the fluorescent lamp support part so that it is perpendicular to the tube axis direction, and the socket body, quick-connect block, and glow lamp socket are covered by the cover, so that the quick-connect block and glow lamp socket can be easily connected. The lamp socket is housed between the fluorescent lamp supports at both ends of the socket body, and the entire two-lamp fluorescent lamp socket can be made relatively compact, and the wiring inside the socket can be easily connected without using solder. It has the advantage of good workability.

In addition, the glow lamp socket is configured to be perpendicular to the tube axis of the fluorescent lamp, so the tip of the glow lamp does not sag due to its own weight, and the contacts between the glow lamp and the glow lamp socket are in contact with each other. No defects occur. Furthermore, when performing maintenance and inspection inside the lighting fixture, the reflector can be attached or removed while the glow lamp is attached to the glow lamp socket, and when packaging the fluorescent lighting fixture, it is possible to remove the reflector from the glow lamp. Since the glow lamp does not protrude from the glow lamp socket body, it has various advantages such as being able to package the glow lamp while being attached to the glow lamp socket, and has great utility value.
