Description

[Detailed Description of the Invention] The present invention relates to an improvement of a ground wire attachment member for a cathode ray tube used in a television receiver or the like.

Conventionally, a cathode ray tube ground wire attachment member has used an annular string 1 as shown in FIG.

In this method, a string 1 is inserted and hooked onto a cathode ray tube support piece 6 fixed together with a band 5 at the four corners around the periphery 4 of a face plate 3 of a cathode ray tube 2, and a ground wire 7 is inserted and hooked at the other end.

The ground wire 7 is stretched so as to be in contact with an external conductive film 9 (provided to cover substantially the entire outer surface of the funnel 8) provided on the funnel 8 of the cathode ray tube at approximately three circumferences of the funnel 8.
A spring 10 is connected to the end or intermediate portion of the ground wire 7 to ensure the contact.

However, according to the conventional member 1 described above, since the cathode ray tubes 2 come in various sizes, several types of strings 1 had to be prepared.

Furthermore, when the string 1 is hooked onto the support piece 6, there are drawbacks such as poor workability, such as the string 1 being pulled out from the support piece 6 due to the weight of the string 1.

This proposal was proposed in view of the above points, and the purpose is to allow the string 1 to be stretched at a substantially constant position on the funnel 8, regardless of the size of the cathode ray tube 2, even if it is used as a common component. The main purpose is

Fig. 2 shows an embodiment of the present invention, in which it is a perspective view of the case mounted on a cathode ray tube 2, Fig. 3 is a perspective view of the cathode ray tube ground wire mounting member 15, and Figs. 4 and 5 show the ground wire. A state diagram showing a preferred example of attaching the attachment member 15 and the end of the ground wire 7 is shown.

The ground wire attachment member 15 has a cathode ray tube support piece insertion part 17 having a support piece insertion hole 16 into which the cathode ray tube support piece 6 can be inserted at one end, and a ground wire insertion part 17 into which the ground wire 7 can be inserted at the other end. It has a ground wire insertion part 19 having a plurality of holes 18,
It has a connecting portion 20 that connects both of them, and these are integrally formed of a material having appropriate flexibility and insulation properties, such as nylon.

The support piece insertion hole 16 has approximately the same cross-sectional shape as the support piece 6, and the support piece insertion part 17 has an oval shape that is slightly larger than the insertion hole 16.

The ground wire insertion part 19 has an oval shape, but the support piece insertion part 1
7 and the long axes intersect with each other, and the connecting portion 20 has one end connected to the center of the short axis of the support piece insertion portion 19 and the other end connected to the center of the short axis of the ground wire insertion portion 19. has been done.

The ground wire insertion hole 18 has an oval shape, and a plurality of the ground wire insertion holes 18 are arranged so that their long axes are coaxial with the ground wire insertion portion 19.

In the illustrated example, the number is two, but the number can be increased as necessary.

It is preferable that the number of the ground wire insertion holes 18 is small and large enough to allow the common ground wire 7 to be inserted therethrough.

The ground wire attachment member 15 is preferably in the form of a thin plate as a whole, and is preferably flexible along the outer surface of the cathode ray tube funnel.

When the cathode ray tube 2 is the smallest, use the one closest to the support piece insertion part 17 among the plurality of ground wire insertion holes 18 to insert the ground wire. design.

Figure 2 shows the case of the largest cathode ray tube.

When directly inserting the end of the ground wire 7 into the ground wire mounting member 15, first form a predetermined ring 21 on the end of the ground wire 7, as shown in FIG. Insert the ring 21 into the hole 18 from the lower surface to the upper surface, and then insert the ring 21 from one end of the long axis of the support piece insertion part 17 to the center of the connecting part 20. Next, in that state, insert the tip of the ring 21 into the support piece insertion part. The rear ring 21 is inserted from the other end side of the long axis 17 through the connecting part 20 and into the ground wire insertion part 19.

Then, the ring 21 of the ground wire 7 is inserted into the ground wire insertion hole 18, as shown in FIG.

This ground wire attachment member 15 is then inserted into the support piece 6 by inserting it into the support piece insertion hole 16.

The other end of the ground wire 7 is similarly inserted into the support piece 6 adjacent to one end.

The ground wire mounting member 15 inserted into the intermediate support piece 6 may be simply inserted into the ground wire insertion hole 18 from one end of the ground wire 7.

The spring 10 may be connected to an appropriate position of the ground wire 7 as required.

When inserting one end of the ground wire 7 as shown in FIGS. 4 and 5, the size of the ring 21 is approximately half the size of the support piece insertion part 17, and one end of the ring 21 It is necessary that the support piece insertion part 17 side end is in contact with the other end, and the other end is inserted from one end of the support piece insertion part 17.

As described above, according to the present invention, since a plurality of ground wire insertion holes 18 are provided, even if the size of the cathode ray tube 2 changes, any ground wire at an appropriate distance from the support piece insertion hole 16 can be inserted. If the hole 18 is selected and inserted, the ground wire 7 can always be stretched at a constant position of the funnel a of the cathode ray tube, and the ground wire attachment member 15 is compatible.

The ground wire mounting member 15 is flexible, there is no risk of bending and causing the ground wire 7 to reliably touch the cathode ray tube funnel 8, and has insulating properties, so that it can be grounded even when the support piece 6 is made of metal. It has practical effects such as being able to be insulated from the wire 7, being integrally formed, and being inexpensive.

The support piece 6 has a hole 25 for attaching a fixing member such as a screw for attaching the cathode ray tube 2 to a cabinet or the like.

Although it is possible to attach the ground wire attachment member 15 to the support piece 6 using this attachment member, the embodiment is superior in terms of operability.

Furthermore, the shape of the ground wire attachment member 15 is not limited to the embodiment, and can be modified in various ways.
