Description

[Detailed description of the invention] The present invention has a fixed part for fitting the socket into the base at the bottom of the lamp insertion part to form a bi-pin type socket, and A wide notch is provided, and the angle between the upper edge of the notch and the front surface of the rung insertion part is a right angle, and the upper edge of the notch is parallel to the upper surface of the fixing part. To install the socket, press the end of the elastic back cover plate made of synthetic resin provided on the back of the lamp insertion part against the base, and push the lamp insertion part backward to push the elasticity of the back cover plate. The socket installation against force relates to a socket device for a fluorescent lamp which is elastically displaceable at position 1 where the front surface of the lamp insertion part is perpendicular to the base, and its purpose is to install sockets of various lengths. To provide a socket device for a fluorescent lamp in which a lamp can be inserted into a lamp insertion part and a state in which the lamp and the lamp insertion part are always kept in good contact with each other is provided.

The present invention will be explained in detail below with reference to the attached drawings.In the embodiment shown in FIG. 5 is a screw 6 that is tightened to the rear surface 12.

The back cover plate 5 is made of an insulating material such as a plastic material, and the back cover plate 5 of the embodiment shown in FIGS. 1 to 9 is given elasticity so that it can expand and contract in the vertical direction. It's Nishide.

A fixing part 2 is provided at the lower part of the socket A and is a part that is fitted into the base 1 for mounting the socket, and this fixing part 2 is integrally connected to the socket insertion part 3.

The upper end of the front surface 7 of the lamp insertion section 3 is chamfered diagonally to form an inclined surface 8, and the back surface 10 of the fixing section 2 is also inclined in the same direction as the surface 8.

Notches 11 are cut out at the lower ends of both sides of the lamp insertion section 3, and the notches 11 extend from the front surface 7 to the rear surface 1 of the lamp insertion section 3.
It extends through the two housings.

In the illustrated embodiment, the opening width of the notch 11 becomes wider toward the rear end.

Here, the angle between the upper edge of the notch 11 and the front surface of the playing card insertion part 3 is a right angle, and the upper edge of the notch 11 and the upper surface of the fixing part are parallel.

The lower end of the front surface 7 of the lamp insertion portion 3 is provided with a groove portion 13 having a forward opening extending from the notch portions 11 on both sides.

Downward protrusions 14 are formed at the lower ends of both sides of the back cover plate 5 so as to overlap a part of the notch 11, and each downward protrusion 14 extends a part of each notch 11 from the rear side. It's blocked.

In the embodiment shown in FIG. 2, a cutout window 15 is cut out near each downward protrusion 14. As shown in FIG.

When the socket A is attached to the base 1, the upper surface of the rear end 16 of the base 1 hits the downward protrusion 14, and an upward pressing force is generated to push the back cover plate 5 upward. is added to the downward protrusion 14.

When such an upward pressing force is applied to the downward protrusion 14,
Since the groove 13 exists at the lower end of the lamp insertion part 3, the lamp insertion part 3, together with the back cover plate 5, tilts forward toward the insertion side of the lamp 9, and the socket is attached to the base 1 as shown in FIG. It is held in a forward leaning position.

If the lamp insertion part 3 is kept in the forward tilted position shown in FIG. This makes it possible to prevent the lamp from coming off and keep the lamp 9 in good contact with the lamp insertion portion 3 at all times.

The lamp 9 is inserted into the lamp insertion part 3 from above the socket A as shown by the arrow X, but even if the lamp insertion part 3 is in the forward tilted position shown in FIG. Since the upper end is a sloped surface 8, it is easy to insert the lamp 9.

If the lamp 9° is long and the lamp insertion part 3 is pushed backward when inserted into the lamp insertion part 3, the back cover plate 5 will move together with the lamp insertion part 3 toward the position shown by the dotted line in FIG. Displaced rearward, the socket mounting is positioned perpendicular to the base 1.

As the back cover plate 5 moves backward together with the lamp insertion part 3, the upward pressing force applied to the downward protrusion 11 by the upper surface of the rear end 16 increases, and the rear surface 12 of the lamp insertion part 3 increases.
A gradually larger compressive force is applied to the back cover plate 5 embedded in the back cover plate 5.

The back cover plate 5 will elastically contract when compressive force is applied.
This shrinkage of the back cover plate 5 can be absorbed by the cutout window 15 provided near the downward protrusion 11.

Instead of the cutout window 15, a vertical groove 17 shown in FIG. 4, a horizontal groove 18 shown in FIG. 5, and a recess 19 shown in FIGS. may be provided on the back cover plate 5, or the back cover plate 5 itself may be formed into a corrugated shape as shown in FIG.

When the fluorescent lamp socket device according to the present invention is arranged at both ends of a fluorescent lamp luminaire and the front surfaces of the two lamp insertion portions 3 are arranged opposite to each other, the two lamp insertion parts are kept in a forward tilted position. The distance between the parts 3 is adjusted to the length of the lamp 9 whose power consumption is 30 watts or less, and the interval between the two lamp insertion parts 3 located approximately perpendicular to the socket mounting base 1 is adjusted to the length of the lamp 9 whose power consumption is 40 watts or more. By adjusting the length of the lamp 9, both a short lamp with a power consumption of 30 watts or more and a short lamp with a power consumption of 40 watts or more can be fitted into the lamp insertion part 3.

In the present invention, the socket of the lamp insertion part is installed by providing a fixing part for fitting into the base to form a bi-pin type socket, and by creating notches at the lower ends of both sides of the lamp insertion part that become wider towards the rear end. The angle between the upper edge of the notch and the front surface of the lamp insertion part should be a right angle, and the upper edge of the notch should be parallel to the top surface of the fixing part, and when installing the socket, fit the end of the stand into the notch. When installing the socket, press the end of the elastic back cover plate made of synthetic resin provided on the back of the lamp insertion part against the stand, and move the lamp insertion part backward against the elastic force of the back cover plate. The socket installation is elastically displaceable at position 1, where the front surface of the lamp insertion part is perpendicular to the base, so the lamp insertion part can be attached to a back cover plate made of elastic synthetic resin by pressing a button on the bi-pin type socket. The forward leaning position can be maintained by the elastic force, and the lamp insertion part can be displaced against the elastic force of the back cover plate to position 1, where the socket mounting part is perpendicular to the base. The distance between the two lamp insertion parts can be freely changed according to the lamp length within the range of position 1, which is perpendicular to the position , and even if the lamp lengths differ within this range, the back cover plate The lamp insertion portion and the lamp are always in good contact with each other due to the elastic restoring force of the lamp.

Also, since the lamp insertion part does not tilt more than a right angle, the lamp will not fall out even though it is a bi-pin type socket.

In addition, in the present invention, the upper end of the front surface of the lamp insertion part is chamfered diagonally to form an inclined surface, so even though the back cover plate is tilted forward, the inclined surface can be used as a guide. This makes it easier to insert the lamp.

If the fluorescent lamp socket device of the present invention is used in this way,
Lamps of various lengths can be easily inserted into the lamp insertion portion, and the lamp insertion portion and the lamp can always be kept in good contact with each other regardless of the length of the lamp.
