Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device in which a holder portion for holding a baseless light emitting diode display device and a power line connection portion are improved.

In general, light emitting elements such as baseless light emitting diodes can be mounted by bonding the light emitting element to a support base or the like, or by soldering to a printed circuit board.

In addition, the wiring is directly soldered to the lead wires of the light emitting elements.

This type of method is difficult to install, and also requires maintenance.
When replacing due to damage, etc., turn off the power, or...
This required difficult work, as there was a risk that healthy parts would be affected as well, as it required removing the connectors and adhesive parts.

The purpose of this invention is to connect a socket with a light emitting element and a case that holds the socket and has connection pins for external wiring in a separable manner, thereby greatly simplifying the work of connecting to external wiring and replacing the light emitting element. The object of the present invention is to provide a display device that is easy to use.

The present invention will be described below with reference to an embodiment shown in the drawings.

FIG. 1 shows the entire display device of the present invention, FIG. 2 shows a case portion, and FIG. 3 shows a socket portion with a light emitting element.

In Fig. 2, T is a panel for attaching a display panel (failure display panel, etc.), which is provided with a hole 7-1 for exposing a light-emitting element, for example, a light-emitting diode 3, and has a case made of, for example, an insulating material on its back side. 1 is fixed with adhesive 7-2.

This case 1 has a hole 1-2 with a diameter that is approximately the same as or larger than the hole 7-1, and a hole 1-2 that communicates with this hole 1-2.
1 on the same axis.

This hole 1-1 is for holding the socket 6 shown in FIG. 3, and a recess 1-1 is formed in a part of the inner circumference as shown in FIG. establish.

Also, in this hole 1-1, a pair of supports m1-
3 is formed along the axial direction, and a connecting pin 2 shown in FIG. 5 is provided therein.

This pin 2 consists of a connecting portion for connecting the external wiring 8 shown in FIG. 1 and a contact piece 2-1 with the socket 6 side.

FIG. 3 shows the socket 6 installed in the hole 1-1, and its detailed structure will be explained in conjunction with FIG. 6.

The main body part 6-1 has the hole 1-1 as shown in FIG. 6e.
(shown in FIG. 4), and is removably connected to this hole 1-1.

As shown in the figure d, a handling glue 6-2 extending to the right is formed in the center of the hole, and this hole 6-2 is also formed.
A recess 6-3 is formed on both sides of -2.

6-4 is a lead hole for the light emitting diode 3 shown in FIG. 6a.
Insert the lead 3-1.

FIG. 6 shows the contact piece 4.

This contact piece 4 is held in support grooves 6-5 formed on both sides of the main body part 6-1, and when installed in the hole 1-1, the contact piece 2-1 of the connecting pin 2 Make conductive contact.

The lead hole 6-4 and the support groove 6-5 are formed so as to reach the inside of the recess 6-3 on the right side from the left end surface in FIG. 6d.

When the light emitting diode 3 shown in FIG. 6a is attached to the main body 6-1, the light emitting diode 3 shown in FIG. It is attached via the base 5.

That is, the lead 3-1 of the light emitting diode 3 is connected to the insulating base 5.
After inserting it into the lead hole 5-1 of the main body part 6-1, the light emitting diode 3 is attached to the left end surface of the main body part 6-1 as shown in the figure through the insulating base 5. .

In addition, Fig. 4 shows a case 1 formed into a single body made up of multiple pieces.
-4 is provided.

When assembling the above parts into the display device shown in Fig. 1, insert the socket 6 shown in Fig. 3 into the hole 1-1 of the case 1 shown in Fig. 2 by pinching the socket 6-2. Bye.

By this insertion, the contact piece 4 attached to the socket 6 comes into contact with the contact piece 2-1 of the connecting pin 2 provided in the hole 1-1.

Since the external wiring 8 is connected to the connecting pin 2 as shown in FIG. 1, it is connected to the light emitting diode 3 via the connecting pin 2, the contact 4 on the socket side, and the lead 3-1.

Therefore, the light emitting diode 3 blinks in response to a signal from the external wiring 8.

Here, when inserting the socket, since the end faces of the hole 1-1 and the socket main body 6-1 have a circular part protruding, the socket 6 is always inserted in the same direction due to their fitting relationship. inserted.

Therefore, the light emitting diode 3 will not be inserted with the polarity reversed.

Furthermore, in the event that replacement occurs due to damage, it is sufficient to pull out only the socket 6 from within the hole 1-1, and there is no need to remove external wiring or the like.

In the above embodiment, the external wiring connection pin 2 is used for wrapping wiring, but this portion may be used for soldering wiring, crimping wiring, etc.

Further, the means for fixing the panel γ and the case 1 may be screwed instead of the adhesive T-2.

It is also possible to provide the number of external wiring connection pins 2 equal to the number of display element lead wires.

As described above, according to the present invention, the socket part with the light emitting element and the case part fixed to the fixed panel are separated, and the pins for external wiring are fixed to the case part, so there is no problem with external wiring. This makes it possible to attach and detach the socket part, making it much easier to connect external wiring and replace the display element.
