Abstract

(57) [Abstract] [Purpose] In a mechanism for holding a neck substrate on a CRT, the neck substrate is prevented from coming off due to vibration or impact. [Structure] The CRT sockets 2 mounted on the neck substrate 3 are attached to the terminal pins of the neck portion 1 of the CRT, and between the mounting portions 6 at the four corners of the CRT and the four holes 7 at both ends of the neck substrate 3. The neck substrate holding wire 4 on which the spring 5 is formed is stretched.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a television device and the like, and relates to a neck substrate holding structure.

[0002]

[Prior art]

 As shown in the side view of the main part of FIG. 3A, the conventional method of holding the neck substrate is such that the neck substrate 23 is soldered to the neck substrate 23 via the resin base portion 22 attached to the terminal pin 2 of the CRT 21. Although not shown, the CRT socket 4 can be directly attached to the terminal pin 2 without attaching the base 22 to the terminal pin 2 without attaching the base 22. There is a way to insert it. According to these methods, the CRT socket 4 may loosen or come off from the terminal pin 2 when vibration or shock is applied during transportation. Therefore, as shown in the side view of FIG. 3 (B) and the rear view of FIG. 3 (C), a cushioning material 24 such as a sponge is attached to the back surface of the neck substrate 23 and held by the back surface of the cover 25. . In such a method, since there is an error in the assembly of the entire apparatus and an error in the allowable size of the CRT 21, as a result, there is a variation in the size between the back surface of the neck substrate 23 and the back surface of the cover 25. There is a limit to the absorption of vibrations and shocks by utilizing the elasticity of the material 24, and it is not a reliable method for holding the neck substrate 23. As another method, when connecting the neck substrate 23 to the CRT 21, there is a method in which adhesive is applied (not shown) so that the base 22 and the side surface of the CRT socket 4 are continuous to each other, but at the time of maintenance. The disadvantages of removing and re-installing the adhesive are that it requires peeling or recoating of the adhesive.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and provides a structure for holding a neck substrate that is not detached from the CRT due to vibration and shock and is easily attached and detached.

[0004]

[Means for Solving the Problems] A neck board holding wire formed with a coil-shaped spring is stretched between the mounting portions at the four corners of the CRT and the four holes at both ends of the neck board. A neck substrate holding structure is characterized in that the CRT socket mounted on the neck substrate and the terminal pin of the neck portion of the CRT are urged and fixed to each other by the urging of the spring. .

[0005]

[Action]

 With the above construction, according to the neck substrate holding structure of the present invention, when the neck substrate is mounted on the neck portion of the CRT, the neck substrate holding member is stretched at four positions of the CRT mounting portion and the neck substrate. The neck substrate is biased and fixed in the direction of the neck portion by the biasing of the wire spring. In addition, according to the other neck substrate holding structure, the neck substrate is moved by the spring force of the center portion of the degaussing coil mounted on both sides of the CRT and the neck substrate holding wire stretched at two places on the neck substrate. It is fixed by being urged in the direction of the neck portion.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1A is a top view showing a neck substrate holding structure applied to the present invention, and FIG. 1B is a side view thereof. 2A is a top view showing the other neck substrate holding structure, and FIG. 2B is a side view thereof. In FIGS. 1A and 1B, 1 is a neck portion of a CRT, and a CRT socket 2 is inserted into a terminal pin (not shown) of the neck portion 1. The CRT socket 2 is connected to the copper foil pattern of the neck substrate A3 by soldering to form an electronic circuit. Reference numeral 4 denotes a neck board holding line A, which is made of an elastic material such as a piano wire, and a coil-shaped spring 5 is formed in the middle of the neck board holding wire A. One end of the neck board holding line A is attached with a CRT. A state in which the neck substrate A3 is pulled in the direction of the neck portion 1 by being attached to four portions of the portion 6 and the other end of the other portion being stretched over the four holes A7 arranged at the end portion of the neck substrate A3. Therefore, the CRT socket 2 mounted on the neck board A3 is biased and fixed in the direction of the neck portion 1 while being mounted on the terminal pin (not shown) of the neck portion 1. If the end of the earth wire 8 and one end of the three neck board holding wires A4 are previously combined and integrated, this neck board holding wire A4 is a lead wire drawn from the ground wire 8. May be used as

As another example, as shown in FIGS. 2 (A) and 2 (B), a neck substrate holding wire having the same material as the neck substrate holding wire A and having a coiled spring 5 is formed. B11 is stretched between the center of the degaussing coil 12 mounted on both sides of the CRT and the two holes B14 at both ends of the neck board B13, so that the CRT socket 2 connected to the neck board B13 is The spring 5 is fixed in a state of being biased toward the neck portion 1 by the bias of the spring 5. Note that, for example, if a conductive paint is applied to the coating of the degaussing coil 12 in advance or a resin having conductivity is used, the function of the ground wire can be obtained, and therefore the ground wire need not be used. . By connecting the center portion of the degaussing coil 12 to one end of the neck substrate holding wire B11, the neck substrate holding wire B11 is used as a lead wire pulled out from the degaussing coil 12 also serving as a ground wire. May be.

[0008]

[Effect of device]

 As described above, according to the neck substrate holding structure of the present invention, the cushioning material is attached to the back surface of the neck substrate in the prior art, which is more securely fixed than the holding method that absorbs shocks and vibrations with the cover. In addition, the neck substrate holding line can also serve as the lead of the ground line. In addition, if the coating of the degaussing coil which is the other embodiment is made conductive, it also has the effect of making it unnecessary to use the ground wire used in the prior art.
