Description

[Detailed description of the device]

[0001]

[Industrial applications]

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

[0002]

[Prior art]

 In the conventional neck substrate holding structure, as shown in the side view of the main part of FIG. 3A, a resin CRT socket 4 soldered to the neck substrate 23 is inserted and attached to the terminal 2 of the CRT 21. In general, the neck base plate 23 is held by the contact pressure between the CRT socket 4 and the terminal 2. According to these structures, in recent years, the shape of the neck substrate 23 has tended to increase in size. Therefore, when vibration or the like during transportation is applied, the neck substrate 23 is loosened between the terminal 2 and the CRT socket 4 or Disorders such as disengagement may occur. Therefore, as a countermeasure against these, as shown in the side view of FIG. 3B and the rear view of FIG. 3C, a cushioning material 24 such as a sponge is attached to the back surface of the neck substrate 23, and In some cases, the back surface of the cover 25 is applied to the back surface to prevent the neck substrate 23 from loosening from the terminals 2 of the CRT 21. Since these structures are different in the assembly error of the entire apparatus and the allowable size of the CRT 21, as a result, the dimension between the back surface of the neck substrate 23 and the back surface of the cover 25 varies. However, there is a limit to the absorption of vibration and shock using the elasticity of the cushioning material 24. Further, in order to avoid damage caused by an impact such as a drop during transportation, a required gap is required for the distance between the back surface of the neck substrate 23 and the back surface of the cover 25. In reality, it is not possible to use the cushioning material 24 having a hardness, so that the structure for holding the neck substrate 23 is not reliable. As another method, when attaching the neck substrate 23 to the CRT 21, there is a method in which an adhesive is continuously applied (not shown) to the side surfaces of the base 22 and the CRT socket 4 to fix it. There is also a drawback that the adhesive must be peeled off or re-applied for removal and re-attachment at that time, and a more reliable and easy-maintenance neck substrate holding structure has been desired.

[0003]

[Problems to be solved by the device]

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

[0004]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a cylindrical moving member having a slanted portion that expands from one end to the other end on the inner periphery of a neck portion of a CRT and a locking claw at the other end. An inclined portion is formed on the outer periphery of the other end, the inclined portion being in contact with the inclined portion, and a fixing member having an attachment portion is inserted at one end to fix the attachment portion and the neck portion. A neck base plate having a hole corresponding to the locking claw and a CRT socket is attached to the terminal of the terminal, and the locking claw is fitted into the hole to fix the movable member to the inclined portion. It is characterized in that the inclined portion of the member is pressed into contact with the neck substrate to hold the neck substrate.

[0005]

[Action]

 With the above structure, according to the neck substrate holding structure of the present invention, when the neck substrate is attached to the neck portion of the CRT, the fixing member fixed to the neck portion with, for example, an adhesive or a band. The slanted part of the moving member is closely contacted with the slanted part of the moving member, and the hole provided on the neck board is fitted into the locking claw that is erected on the other end of the moving member. When the provided CRT socket is mounted, the inclined portion of the fixed member is brought into pressure contact with the inclined portion of the moving member, and the neck substrate is held by the neck portion by the locking claw and the terminal. It When pulling out the neck board from the neck portion, hold the tip of the locking claw fitted in the hole of the neck board with something like pliers, and remove the hole from the locking claw. By separating the moving member from the fixed member, the CRT socket can be pulled out from the terminal of the neck portion, and thus the neck substrate can be easily removed from the neck portion.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side sectional view showing a neck substrate holding structure applied to the present invention, and FIG. 2 is a side sectional view showing a neck substrate mounted on the CRT shown in FIG. FIG. 3 is a side view of an essential part showing one embodiment. In FIG. 1, reference numeral 1 denotes a neck portion of a CRT, and a terminal 2 is arranged around a circumference of one end of the neck portion 1, and a resin base 4 having a cylindrical guide shaft 3 in the center portion is provided on the terminal 2.
