[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a degaussing coil clamper used for fixing a degaussing coil attached to a cathode ray tube in a housing of a device.

[0002]

2. Description of the Related Art There is the following method for fixing a degaussing coil attached to a cathode ray tube.

First, as shown in FIG. 6, a lug 60 is attached to an attachment piece 51 of the cathode ray tube 50, and a locking claw 61 of the lug 60 is attached.
The degaussing coil K is stretched over and the entire degaussing coil K is fixed as shown in FIG. After that, the cathode ray tube 50 is inserted into the housing (not shown) together with the fixed degaussing coil K, and the mounting piece 51 of the cathode ray tube 50 is screwed to the mounting boss (not shown) provided in the housing. The cathode ray tube 50 is fixed.

In this method, the cathode ray tube 50 and the degaussing coil K are used.
This requires a sub-assembly process for assembling the components (1) and (2), which is not desirable in process organization.

In order to solve the above problems, there is a method of fixing the degaussing coil by the degaussing coil clamper 80 shown in FIG. As a procedure for fixing the degaussing coil, the degaussing coil clamper 80 is fixed to the locking holes 71a on the mounting spacers 71 provided at the four corners of the housing 70 by the locking claws 81, and the mounting piece 51 of the cathode ray tube 50 is fixed.
Is fixed to the screw hole 71b of the mounting spacer 71 to fix the cathode ray tube 50, and a degaussing coil (not shown) is stretched in a holding portion 82 formed at the other end of the degaussing coil clamper 80 to form the degaussing coil. It is performed in the order of fixing and does not require a subassembly process.

[0006]

The degaussing coil clamper 80 shown in FIG. 8 is rod-shaped, and it has a cathode ray tube 50.
Since it is necessary to mount the demagnetization coil clamper 80 close to the cathode ray tube 50, it is necessary to narrow the gap between the demagnetization coil clamper 80 and the cathode ray tube 50. For this reason, as shown in FIG. 9, when the cathode ray tube 50 is inserted into the housing 70, the attachment piece 51 of the cathode ray tube 50 may come into contact and be damaged. That is, the workability of inserting the cathode ray tube 50 into the housing 70 deteriorates, which causes the productivity of the device to deteriorate.

It is roughly composed of a substantially U-shaped movable portion 30 connected to the fixed portion 10 via the flexible portions 20 and 20, respectively. This degaussing coil clamper 1 is resin molded.

The fixed portion 10 is a mounting piece 51 of the cathode ray tube 50.
The widthwise end portions 11 and 11 extend upward and are higher than the center. Both ends 1
Projecting pieces (locked portions) 12 and 12 are provided at the tips of 1 and 11, respectively. Further, a tongue piece 13 is provided at the center of the fixed portion 10.
Extends horizontally. The tongue piece 13 is formed with a hole 13a corresponding to the outer diameter of the mounting boss 41. In addition, 1
2a and 12a are tapered portions formed on the protrusions 12 and 12, respectively, and 14a and 14b are bosses 42a and 42 of the housing 40, respectively.
It is a concave portion formed in consideration of b.

The flexible portions 20, 20 are connected to the middles of both ends 11, 11 of the fixed portion 10, respectively. The flexible portions 20 and 20 are thin and have flexibility.

A substantially U-shaped movable portion 30 extending in the horizontal direction.
Surrounds the tongue piece 13 of the fixed portion 10. Flexible part 20,
Locking claws (locking portions) 31, 31 extending upward are respectively provided near both ends of the movable portion 30 close to 20.

Reference numerals 31a and 31a are taper portions formed on the locking claws 31 and 31, respectively.

In the degaussing coil clamper 1 according to this structure, the projecting pieces 12 and 12 on the fixed portion 10 side and the locking claws 31 and 31 on the movable portion 30 side are not locked, and the movable portion 30 and the tongue piece 1 are provided.
3 and the first state [see FIG. 5 (a)] in which the flexible portions 20 and 20 are in a substantially parallel relationship, and the projecting pieces 12 and 12 on the side of the fixed portion 10 are utilized. Locking claw 3 on the movable part 30 side
By locking with 1, 31, the tongue piece 13 and the movable portion 30 can be selectively brought into a second state [see FIG. 5 (b)] in which the tongue piece 13 and the movable portion 30 are in a substantially orthogonal relationship.

Next, a method of using the degaussing coil clamper 1 will be described.

First, the degaussing coil clamper 1 is set to the first state, the hole 13a on the degaussing coil clamper 1 side is fitted into the mounting boss 41 on the housing 40 side, and the tongue piece 13 on the degaussing coil clamper 1 side is mounted on the housing. 40 side ribs 43a, 43b, 43c
Put it on top. At the same time, the recess 1 on the degaussing coil clamper 1 side
4a and 14b are provided along the outer circumferences of the bosses 42a and 42b, respectively. As a result, as shown in FIG. 3, the degaussing coil clamper 1 is aligned with the mounting boss 41. There are various possible configurations for aligning the degaussing coil clamper 1. For example, as shown in FIG. 4, the hole 13a on the degaussing coil clamper 1 side is provided with a taper, and the mounting boss 4
It is also possible to elastically align the degaussing coil clamper 1 by strongly pressing the hole 13a toward 1.
That is, the degaussing coil clamper 1 can be positioned with respect to the mounting boss 41 on the housing 40 side by utilizing the hole 13a on the degaussing coil clamper 1 side.

After that, the cathode ray tube 50 is inserted into the housing 40. At this time, due to the space formed inside the movable portion 30 of the degaussing coil clamper 1, the mounting piece 5 of the cathode ray tube 50 is
The passage of 1 is not blocked. That is, the flexible portions 20, 20 are wider than the mounting piece 51 of the cathode ray tube 50.
Since the movable portion 30 is located at both ends of the cathode ray tube 50 and has a substantially U-shape so as to surround the attachment piece 51 of the cathode ray tube 50 which enters, the attachment portion 51 of the cathode ray tube 50 is inserted during the insertion of the cathode ray tube 50.
Does not come into contact with the flexible parts 20, 20 or the movable part 30. Therefore, there is no risk of damaging the degaussing coil clamper 1, and the workability of inserting the cathode ray tube 50 into the housing 40 is improved. When the insertion of the cathode ray tube 50 is completed, as shown in FIG. 5A, the tongue piece 1 of the degaussing coil clamper 1 is
The attachment piece 51 of the cathode ray tube 50 abuts on 3.

After that, the tongue piece 13 on the side of the degaussing coil clamper 1 is screwed to the mounting boss 41 together with the mounting piece 51 of the cathode ray tube 50 using the mounting screw N. As a result, the degaussing coil clamper 1 is fixed. Then, the degaussing coil clamper 1
Is displaced from the first state to the second state shown in FIG. 5 (b). Since the locking claws 31 and 31 on the movable portion 30 side and the protrusions 12 and 12 on the fixed portion 10 side are formed with tapered portions 31a and 31a and tapered portions 12a and 12a, respectively. Pawls 31, 31 and protrusions 12, 1
The locking of 2 can be performed smoothly. When the degaussing coil clamper 1 is in the second state, the locking claw 32 is close to the cathode ray tube 50, so that the degaussing coil K can be fixed by stretching the degaussing coil K here.

[0019]

From the above description, the degaussing coil clamper according to the present invention does not require a sub-assembly process for fixing the degaussing coil, and when the cathode ray tube is inserted into the housing, the cathode ray tube is mounted. The pieces will not come into contact and be damaged. Therefore, there is an excellent effect that the workability of inserting the cathode ray tube into the housing is improved and the productivity of the device is improved.
