Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lamp mounting device for, for example, an illuminated push button switch.

The present invention facilitates the replacement work of flange base type lamps, and its structure is such that a base having external terminals 16 and 17 is provided at the bottom of the box 1, and a gutter-like structure is provided at the base. A support body 2 is erected, a lamp socket 3 having a lamp insertion hole 5 and a grip part 7 projecting upward on one side is removably fitted into the support body 2, and a conductive plate is provided on the outside of the grip part 7. A fixing plate 14 formed by extending the lower end of the conductive plate 8 and bending its tip into a U-shaped cross section is inserted into the lamp insertion hole 5, and the locking part 9 provided on the outside of the conductive plate 8 is connected to one outside. Contact plate 1 provided with terminal 16 extending upward
0, the lamp 4 is inserted into the fixing plate 14, and the bottom terminal 12 of the lamp 4 is brought into contact with the connecting plate 13 provided on the other external terminal 17. This lamp mounting device is characterized by:

The present invention will be described in detail below based on one embodiment.

A lamp for attaching a flange base type lamp 4 to a lamp socket 3 made of an appropriate material, which is removably fitted to a gutter-shaped support 2 that stands upright from the base of a box 1 integrally formed of synthetic resin or the like. A grip part 7 having an insertion hole 5 and a window part 6 near the upper end is provided upright at one end of the upper surface of the lamp socket 3.

The conductive plate 8 provided on the outer surface of the gripping portion 7 is extended to the vicinity of the lower opening of the lamp insertion hole 5. The conductive plate 8 is provided with a locking portion 9 having an appropriate shape such as a concave or convex shape.

When the aforementioned lamp socket 3 is inserted, the conduction plate 8
The inner surface of the contact plate 10, which is installed upright at the base of the box 1 so as to slightly dig into the inner surface of the support body 2 at the position where it comes into contact with the contact plate 10, has a lock for locking the locking portion 9 provided on the conductive plate 8. A stopper 11 is provided.

Further, an elastic connection plate 13 for the bottom terminal 12 is provided at the inner bottom of the support body 2 . The lamp is fixed inside the lamp socket 3 and the lamp insertion hole 5 by a fixing plate 14 which is bent into a U-shaped cross section with the tip of the extension of the conductive plate 8 directed slightly inward from the lamp insertion hole 5. ing. In the figure, 15 is the base of the lamp 4, 16 is an external terminal connected to the contact plate 10,
17 is an external terminal connected to the connection plate 13.

Further, in the embodiment, the locking body 11 is a protrusion, and the locking portion 9 is a concave or convex shape, but the shape is not limited to this, and any suitable method may be used.
In the embodiment of the present invention, the shape of the lamp socket is a cylindrical shape with a portion cut away, but the shape is not limited to this.

Since the present invention is constructed as described above, the flange base type lamp 4 is inserted through the lower opening of the lamp insertion hole 5 of the lamp socket 3 until the flange portion of the lamp base 15 reaches the conductive plate 8. insert. At this time, the lamp 4 is inserted so as to spread the fixed plate 14 apart.

Place the lamp socket 3 into which the lamp 4 is inserted into the box body 1.
into the support body 2 of. At this time, the contact plate 10 comes into contact with the conductive plate 8 of the lamp socket 3, and the locking part 9 is locked with the locking body 11. Further, the bottom terminal 12 of the lamp 4 comes into contact with a connecting plate 13 provided at the inner bottom of the support body 2.

Therefore, the lamp 4 is connected to the external terminal 16 - the contact plate 10
- Conductive plate 8 - Base 15 - Lamp 4 - Bottom terminal 12 -
An external terminal 17 and an electric circuit for lamp illumination are formed. To remove the lamp now, insert the tip of a suitable tool such as a screwdriver or tweezers into the window 6 of the grip 7 and pull it up in the direction of the arrow in FIG. The stop is removed and lamp socket 3 can be removed.

Therefore, according to the present invention, when replacing the lamp, the lamp socket 3 can be removed by lightly pulling up the window part 6 of the grip part 7, which can be done very easily.

In other words, the grip portion 7 of the lamp socket 3 is located directly above the contact plate 10, and the contact plate 10 itself moves somewhat backward. Therefore, when the lamp socket is unlocked, the force applied to the grip portion 7 can be more easily applied to the contact plate, and the lock can be unlocked with less force.

Furthermore, since the lamp socket itself is securely locked by the locking body 11 of the contact plate 10, it is possible to prevent the lamp socket from coming off due to vibrations, etc., and since the structure itself is simple, it can be produced in large quantities at low cost. It has the following effects.
