Description

The present invention relates to a CRT display monitor using a CRT,
The present invention relates to a CRT printed board holding device for a display device such as a television receiver.

2. Description of the Related Art In recent years, with the development of computers, the use of CRT display monitors, which are display devices, has been expanded. Along with this, unnecessary radiation is also becoming a major problem, and there are increasing examples of countermeasures by centralizing the circuit that is the source of the radiation and surrounding it with a shielding material. Because of this,
The printed circuit board attached to the CRT neck part (hereinafter referred to as CRT printed circuit board) is also increasingly surrounded by a shield material or the like because the circuit is concentrated. As a result, the weight of the CRT printed circuit board enclosed by the shield increases, and the fixing method becomes difficult.

Hereinafter, a conventional CRT printed board holding device will be described with reference to the drawings.

FIG. 6 shows a conventional printed board holding device. In FIG. 6, 1 is a CRT, 2 is a CRT printed board, 3
Is a CRT socket which is soldered to the CRT printed board 2. 4 is a shield plate and 5 is a silicone adhesive.
1a shows the neck of CRT1.

Hereinafter, a method of holding the CRT printed board holding device configured as described above will be described.

Insert the CRT socket 3 into the CRT neck 1a. This CRT
The neck portion 1a is provided with a pin corresponding to the CRT socket 3 and is fitted and held. Although it can be used in this state, there is a possibility that the CRT socket 3 may fall off during transportation or when an impact is applied. For this reason, the silicone adhesive 5 is applied and fixed so as to straddle the CRT socket 3 and the CRT neck 1a.

However, in the above method, the shield plate 4
However, there is a problem that the workability of applying the silicon-based adhesive 5 becomes more difficult with the addition of. Also, when it becomes necessary to remove the CRT print 2 during service and repair, the silicon adhesive 5 is peeled off, so that the workability is extremely long, and the work can be easily removed and easily restored. The structure was desired.

In view of the above problems, the present invention can be easily attached and fixed even when the shield plate is attached to the CRT printed board when the CRT printed board is attached, and can be easily removed during service, and An object of the present invention is to provide a CRT printed board holding device that can be restored.

Means for Solving the Problems In order to solve the above problems, a CRT printed board holding device of the present invention uses a CRT print holder having a CRT printed board insertion portion and a CRT neck portion fixing portion, and converts the CRT printed board to a CR.
At the time of insertion into T, insert the CRT printed board insertion part of the CRT print holder into the CRT printed board and insert the CRT neck fixing part into the CRT
It has a configuration in which it is fixed to the neck with a silicone-based adhesive.

Effect of the Invention With the above-described configuration, the present invention can reliably perform fixing with a silicon-based adhesive even when a shield plate is inserted into a CRT printed board, and at the time of service, a CR is used.
By deforming the rib of the CRT printed board fixing part of the CRT printed holder from the back of the T printed board with pliers, it can be detached from the CRT printed board, so that the CRT printed board can be easily removed and repaired, and easily It is possible to restore the original state.

Embodiment Hereinafter, a CRT printed board holding device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a CRT printed board holding device according to an embodiment of the present invention. In FIG. 1, 1 is a CRT, 2
Is a CRT printed board, 3 is a CRT socket, 4 is a shield plate, 1a is a CRT neck portion, and the above is the same as the configuration of FIG. 6 (conventional example). 5 is silicone adhesive, 6 is CR
This is a T print holder and has a printed board fixing portion 6a and a CRT fixing portion 6b.

FIG. 5 is a plan view of the CRT print holder 6 alone.

A stepped rib 6c is positioned on the printed board fixing portion 6a so as to have a cantilevered end portion, and has a semicircular rib 6d positioned perpendicular to the rib 6c. The CRT fixing portion 6b has a semi-circular plate 6g having a through hole 6e and a groove 6f.
However, it is formed so as to match the diameter of the CRT neck portion 1a.

The operation of the CRT printed board holding device configured as described above will be described below with reference to FIGS. 2, 3, and 4. FIG.

First, FIG. 2 shows a structure before mounting the CRT print holder 6, in which the CRT print holder 6 is fitted into the CRT neck 1a. From this state, the CRT print holder 6 is slid in the direction A toward the mounting hole 2a provided in the CRT printed board 2, and the printed board fixing portion 6a
Into the mounting hole 2a. Thereby, the position of the CRT print holder 6 is determined. This state is shown in FIG.
In the state shown in FIG. 3, the CRT print holder 6 is fixed by inserting the silicon-based adhesive 5 into the through-hole 6e and the groove 6f.
Normally, the material of the CRT print holder 6 is polyamide (PA)
A system material is used to make use of the elasticity, but this type of material has poor adhesion. Therefore, the silicone adhesive 5 is inserted into the through holes 6e and the grooves 6f provided in the CRT print holder 6.
The adhesive 5 formed between the CRT print holder 6 and the CRT neck 1a and the adhesive 5 formed so that the silicone adhesive 5 overflowing between the through-hole 6e and the groove 6f holds the CRT print holder. The adhesive strength is secured by the strength of the adhesive itself obtained by its own loop. In this state, at the time of service, as shown in FIG. 4, from the side opposite to the CRT print holder 6 insertion of the CRT printed board 2, the printed board fixing portion 6a is moved inwardly with the stepped rib 6c. It can be removed by deforming.

As described above, according to this embodiment, the CRT print holder is provided with the print insertion portion and the CRT fixing portion at both ends, the CRT fixing portion is adhered and fixed, and the print insertion portion can be attached and detached. Even if the plate is covered with a shield case, the mounting operation can be performed easily and reliably, and it can be easily mounted and removed at the time of service.

In the embodiment, the adhesive 5 is a silicon-based adhesive. However, the adhesive 5 may be any adhesive having the same properties. If the adhesive strength can be ensured, the adhesive 5 may not be used, and a double-sided adhesive tape or a spring may be used. In the above embodiment, the CRT print holder 6 is
Although attached to the CRT neck part 1a first, the CRT printed board 2 may be inserted into the CRT printed board 2 in advance, and the CRT printed board 2 may be inserted and attached to the CRT 1, and the CRT print holder 6 and the CRT neck part 1a may be fitted together. .

Advantageous Effects of the Invention As described above, according to the present invention, a CRT having separate insertion and fixing portions to a CRT printed board and fixing portions to a CRT neck portion at both ends is provided.
By providing the RT print holder, the CRT printed board can be easily fixed and held on the CRT by using an adhesive or the like. Easy without peeling
It is possible to attach and remove CRT printed boards.
