Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a socket mounting device for a lighting fixture.

Conventionally, general lighting equipment, such as the inverted Fuji type 2 shown in Fig.
In a light-type lighting device, a U-shaped device main body 2 containing electrical components is fixed on a mounting board 1, and socket mounting plates 3 are fixed to both ends of the U-shaped device main body 2, and the U-shaped device body 2 shown in FIG. Insert and hold the horizontal grooves 6 on both left and right sides of the root of the socket 5 into the socket insertion holding hole 4 of the board 1 in this state.
is attached and fixed to the ceiling 7 using anchor bolts or the like, and then a reflector 8 is attached.

However, with this socket mounting structure, when the board 1 is tilted during installation work below the ceiling, the socket 5 on the lower end side
The slip-out slides down to the opening side of the insertion holding hole 4.

That is, since the socket is molded with resin, the dimensional accuracy of the groove part is low, and if it is forced in, cracks will occur, resulting in a loose insertion, which makes it difficult to pull out, resulting in poor workability.

For this reason, various measures have been taken to utilize the elasticity of the socket mounting plate 3 made of silver and gold to prevent it from coming off.

For example, as shown in Fig. 6, small protrusions 4'' are formed on the plate surface of both side edges 4' of the insertion holding hole 4 to firmly insert and hold the socket horizontal groove 6 so that it is difficult to remove. However, there was a problem in that the socket could not be easily removed when it was necessary to remove it for maintenance, equipment inspection, etc.

The present invention is an improvement on the above points,
The bottom of the tank is explained as follows based on the drawing.

As shown in Fig. 2, a socket insertion hole 9 with a diameter larger than the socket root is formed in a continuous opening on the plate surface of the socket mounting plate 3 on the notch opening side of the U-shaped socket insertion holding hole 4. A pair of narrow, elongated and elastic tongues 10 are integrally punched out from the socket (dotted lines in the figure) on the left and right edges of the insertion hole 9 so as to protrude toward the holding hole 4. do.

When the root of the socket 5 is inserted into the insertion hole 9 at right angles, the pair of tongues 10 are elastically bent upward as shown in FIG. 4, then slide the socket 5 into the holding hole 4 and insert the socket 5 into the horizontal grooves 6 on both sides as shown by the dotted lines in Fig. 2 between the holding type side edges 4'. Let socket 5
The front side of the tongue piece 10 is brought into contact with the front side edge 4'' of the hole, and in response to this, the tongue piece 10 is brought down to the insertion hole surface by the restoring elasticity, and its tip is placed on both the left and right sides of the socket 5 as shown in FIG. It comes into contact with the rear side of the socket like a stopper to prevent the socket from coming out.

When removing the socket, push and bend the tongue piece 10 on the insertion hole surface a little upwards and pull the socket 5 sideways into the insertion hole part 9.
Then pull it out downwards.

As described above, according to the present invention, since a pair of tongue pieces are formed on the left and right sides of the socket insertion hole of the socket mounting plate, when the socket slides from the insertion hole to the insertion holding hole, The sliding operation can be performed smoothly without tilting, and even when the socket is inserted, both the left and right sides of the socket are locked by tongues, which prevents the socket from tilting and makes it easier to mount the lamp. In addition, when removing the socket, it is possible to automatically prevent the socket from being removed, and when removing the socket, the tongue piece is slightly bent and the socket I is easily pulled out into the insertion hole. be able to.

Claims (1)

[Scope of utility model registration request] An insertion hole for inserting a resin socket at right angles is formed in the plate surface on the side of the socket insertion holding hole of the socket mounting plate in a continuous opening shape, and the socket is inserted into this insertion hole to insert the socket. The socket is attached to the socket mounting plate by sliding it toward the insertion hole side and engaging the horizontal grooves of the socket root with both side edges of the socket insertion holding hole. A pair of elastic tongues that are narrower in width than the socket extend toward the socket insertion holding hole, and are elastically deformed when the socket is inserted into the insertion hole, thereby creating a socket difference. What is claimed is: 1. A socket mounting device for a lighting fixture, characterized in that the socket is restored by engagement with the socket holding hole and is integrally provided on both left and right sides of the rear side surface of the socket to prevent the socket from being pulled out.
