Description

[Detailed Description of the Invention] The present invention relates to a lighting fixture, and in particular to an improvement in the structure for drawing out a lead wire with a socket from a component storage chamber in a round fluorescent lamp fixture.

In conventional devices of this kind, the lead wire equipped with a socket is pulled out together with the socket from a hole formed in the bottom plate of the component storage chamber, but since the diameter of the socket is significantly larger than that of the lead wire, The pores are also inevitably larger.

Therefore, large holes are exposed when in use,
Not only is it unfavorable in appearance, it is easy for fingers to enter the parts storage chamber through the hole, and there is a risk of electric shock by touching the live parts inside.Furthermore, if tension is applied to the lead wire, it is difficult to place the lead wire in the parts storage chamber. There is a drawback that the terminal part inside the room can easily come off.

In view of these points, this proposal improves the appearance characteristics of the bottom plate part, reduces the risk of contact with live parts in the parts storage chamber, and reduces as much as possible the external force acting on the terminal part of the lead wire. The present invention provides a lighting fixture, and examples thereof will be described below.

In the figure, 1 is a top plate part, 2 is a parts storage chamber arranged in the center of the top plate part 1, and 3 is a bottom plate part thereof.

Reference numeral 4 denotes an elongated window hole, for example, formed in an arbitrary part of the bottom plate part 3, and U-shaped notches 5 and 6, for example, are formed on the long side of the hole so as to communicate with the window hole. has been done.

Reference numeral 7 denotes a screw hole formed in a portion adjacent to the window hole 4, and is used for attaching a bushing, which will be described later.

8 is a window hole for protruding a 0 ball, for example.

9 and 10 are glow lamps arranged in the parts storage chamber 2, 0
These are sockets for balls, and are fixed so as to face the window holes 4 and 8, respectively.

11゜12 are sockets) 9. The glow lamp attached to 10, 0 bulbs.

A bushing 13 is attached to the window hole 4 and is made of a slightly elastic resin material such as polypropylene.

Reference numeral 14 denotes a bushing body formed in substantially the same shape as the window hole 4, and a through hole 15, 16 having an inner diameter slightly larger than the outer diameter of the glow lamp 11, for example, is formed in the bushing body.

Reference numeral 17 denotes a flange portion extending outward from the upper end edge of the bushing body 14, and is formed to have a larger diameter than the window hole 4.

Reference numeral 18 denotes a mounting lug extending further outward from the flange portion 17, and a screw hole (through hole) 19 corresponding to the screw hole 7 in the bottom plate portion 3 is formed in the center of the lug.

Reference numeral 20 designates a locking portion protruding from the side wall portion of the bushing body 14, and is integrally formed with the flange portion 17 so that the bottom plate portion 3 is sandwiched therebetween.

Recesses 21 and 22 are formed in the long side walls of the bushing body 14, and oppose the notches 5 and 6 when the bushing 13 is installed in the window hole 4, forming a space 24.

25 is a lead wire having one end connected to the parts storage chamber 2 and the other end connected to a socket 26, which is formed between the notches 5 and 6 of the window hole 4 and the side wall (recesses 21 and 22) of the bushing 13. It is led out from the space 24 in a pinched manner.

27 is a round fluorescent lamp, and 28 is a rectangular or large-sized shade attached to the top plate portion 1.

Next, a method for leading out the lead wire 25 will be explained.

First, as shown in FIG.
Pull it out from the notches 5 and 6.

In this state, when the bushing 13 is attached to the window hole 4, the locking part 20 is pressed and deformed by the peripheral edge of the window hole 4 and placed inside the bottom plate part 3, and the bushing 13 is connected to the seven flange section 17 and the locking part 20. It is locked in the window hole 4 by.

At the same time, the lead wire 25.25 is held between the recess 21.22 and the notches 5, 6 in the side wall of the bushing 13.

Then, the bushing 13 is securely fixed to the bottom plate portion 3 by screwing the screws 23 into the screw holes 18 and 7.

Next, the glow lamp 11 is attached to the socket 9 through the through holes 15 and 16 of the bushing 13, and the lead wires are led out.

In this way, the lead wire 25 is clamped and fixed by the notches 5 and 6 of the window hole 4 and the recesses 21 and 22 in the side wall of the bushing 13, so that even if tension is applied to the lead wire protruding into the lamp chamber, the parts will not be damaged. It does not act on the connection terminal portion in the storage chamber 2 at all, and the terminal displacement can be significantly reduced.

In particular, if the bushing 13 is fixed to the bottom plate part 3 with the screws 23, the ability to hold the lead wire 25 is improved, and the action of external force on the terminal part can be further reduced.

Further, since the lead wire 25 is led out from the extremely narrow space 24 formed between the notches 5 and 6 and the side wall of the bushing 13, the appearance of the bottom plate 3 is improved and the product value is improved. can.

Furthermore, since the window hole 4 is closed by the bushing 13, it is impossible to insert a finger into the parts storage chamber 2, so that the risk of electric shock can be completely eliminated.

Furthermore, the recesses 21 and 22 in the side wall of the bushing 13
By forming the lead wire 25 into a substantially U-shape, the lead wire 25 can be easily bent, and the tension acting on the lead wire 25 on the internal terminal portion can be further reduced.

Especially around the glow lamp 11 is an insulating bushing 13.
Since the bottom plate part 3 is insulated and protected, the base part does not come into contact with the bottom plate part 3 when it is attached or removed, and the circuit components can be reliably protected.

Note that the present invention is not limited to the above embodiments in any way,
For example, the number of through holes in the bushing can be one, and the number of recesses in the side wall of the bushing can be increased or decreased depending on the number of lights.

Further, the recess can be omitted in relation to the notch.

As described above, according to the present invention, by clamping and fixing the lead wire by attaching it to the window hole of the bushing, it is possible to improve the appearance characteristics and reduce the risk of contact with live parts in the parts storage chamber. Excellent effects such as reducing the external force acting on the terminal portion of the lead wire and greatly reducing terminal misalignment can be obtained.
