DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp rubber holder used for a display such as a liquid crystal television and a personal computer.

[0002]

2. Description of the Related Art In recent years, transmission type liquid crystal display devices have been widely used for display devices such as portable liquid crystal televisions and notebook personal computers. As a surface light source device used in these liquid crystal display devices, an edge light system in which a light guide plate is placed on the back surface of a display body and a line light source is arranged on an end surface of the light guide plate is often adopted. Lamps such as cold-cathode tubes are used for the above line light sources, but since a voltage of several hundred volts is applied to the high-voltage side electrodes of these line light sources, a lamp rubber holder is used to protect them. ing.

Hereinafter, a conventional lamp rubber holder will be described.

FIG. 3 shows an example of a conventional lamp rubber holder, wherein (a) is a front view, (b) is a side view of (a), and (c) is a side view.
It is a bottom view of (a). As shown in FIG. 3, a key-shaped lamp rubber holder 30 has a hole 31 provided in a horizontal portion for horizontally inserting and holding a lamp end portion, and a lamp lead wire provided vertically in a vertical portion. Hole 32.

FIG. 4 shows a front view of the lamp rubber holder of FIG.
a is inserted and held in the lamp insertion holding hole 31,
The lamp lead wire 41 is drawn out from the lamp lead wire outlet hole 32 in a direction perpendicular to the direction in which the lamp 40 is inserted.

FIG. 5 is a view showing another example of a conventional lamp rubber holder, wherein (a) is a front view, (b) is a side view of (a), and (c).
3 is a bottom view of FIG. As shown in FIG. 5, the lamp rubber holder 50 has a hole 51 for inserting and holding a lamp end and a hole 52 for taking out a lamp lead wire.

FIG. 6 shows a front view in which the lamp end is inserted into the lamp holder of FIG.
Is inserted and held in the lamp insertion holding hole 51, and the lamp lead wire 61 is inserted through the lamp lead wire extraction hole 52.
It can be pulled out obliquely downward from almost the same direction as the insertion direction of 50.

[0008]

In the structure of the conventional lamp rubber holder described above, the lamp insertion holding holes 31,
At 51, the ends 40a, 60a of the lamps 40, 60 can be held to protect the lamps. However, the lamp leads 4
Since the lamps 1 and 61 are directly taken out of the lamp lead wire outlet holes 32 and 52 and have no structure for holding the lamp lead wires, the lamp lead wires are entangled with each other at the time of storing and assembling the lamp, and the workability is poor. After the lamp is assembled into the light guide plate, a structure for holding the lamp lead wire in a resin housing or the like is required. Further, since the lamp rubber holder has only one hole 32, 52 for taking out a lead wire, that is, only one direction, the direction of taking out the lamp lead wire cannot be changed between left and right.

In view of the foregoing, it is an object of the present invention to provide a lamp rubber holder which holds a lamp lead wire and can change a direction in which the lamp lead wire is taken out left and right.

[0010]

According to the present invention, there is provided a lamp rubber holder having a key-like shape, wherein a hole provided in a horizontal portion of a lamp rubber holder is provided for inserting and holding a lamp end, A hole for taking out a lamp lead wire provided horizontally in connection with a hole for inserting and holding an end portion, and a hole for taking out a lamp lead wire provided vertically to the vertical portion of the lamp rubber holder. The hole and the hole for inserting and holding the lamp end in a vertical portion of the lamp rubber holder have a through hole for inserting and holding a lamp lead wire provided horizontally in parallel.

[0011]

According to the present invention, by providing a through hole for inserting and holding a lamp lead wire, the lamp lead wire can be held, so that the lamp lead wires do not become entangled with each other during storage and assembly of the lamp. The workability when assembling the lamp is greatly improved. Further, there is no need for a structure for holding a lamp lead wire in a resin housing or the like even after being incorporated in a liquid crystal display device. Furthermore, since the lead holes for the lamp lead wires are provided in two directions, horizontal and vertical,
When the lamp lead wire is taken out of the lamp in the horizontal direction or in the vertical direction, the taking out direction can be changed on the left and right.

[0012]

FIG. 1 is a view showing the structure of a lamp rubber holder according to an embodiment of the present invention, wherein (a) is a front view and (b) is a view.
(a) is a side view, and (c) is a bottom view of (a). In FIG. 1, reference numeral 1 denotes a lamp rubber holder having a key shape, 2 denotes a hole for inserting and holding a lamp end horizontally provided on a horizontal portion of the lamp rubber holder 1 having the key shape, and 3 denotes a hole. A hole 4 for taking out a lamp lead wire provided horizontally and connected to a hole 2 for inserting and holding the lamp end portion, and a lamp lead 4 provided on a vertical portion of the lamp rubber holder 1 vertically to the horizontal portion. A hole 5 for taking out a wire is a lead wire for inserting and holding a lamp lead wire provided horizontally in parallel with a hole 2 for inserting and holding the lamp end in a vertical portion of the lamp rubber holder 1. It is a holding through hole.

FIG. 2 is a configuration diagram of a lamp unit in which a lamp is incorporated in the lamp rubber holder 1 of FIG. 1, (a) is a front view, and (b) is a bottom view of (a).

As shown in FIG. 2, the lamp lead wire 7 can be held by inserting the lamp lead wire 7 into a lead wire holding through hole 5 provided in a part of the lamp rubber holder 1. Further, the lamp lead wire 7 can be taken out on an extension of the lamp insertion direction (right side in FIG. 2), and the lamp lead wire 7 can be taken out from the lamp lead wire outlet hole 4.
Can be taken out perpendicular to the lamp insertion direction
(Left side in FIG. 2), so the take-out direction can be changed between left and right.

The lamp rubber holder 1 is made of, for example, a silicon material, but may be made of a resin material irrespective of the rubber material.

[0016]

As described above, in the lamp rubber holder of the present invention, since the lamp rubber holder is provided for holding the lamp lead wire, the lamp lead wire does not become entangled at the time of storage and assembly, so that the liquid crystal display device can be used. Even after being incorporated in the housing, a structure for holding the lamp lead wire is not particularly required in the resin housing or the like. Further, since the direction in which the lamp lead wire is taken out can be changed between left and right, the design margin of the liquid crystal display device can be improved.
