As shown in the drawing, the shadow mask 3 and the mask frame 5 which form a body through welding are formed inside the panel 1. ) Is fixedly arranged, and the inner shield 7 which is dividedly formed is attached to the flange 5a of the mask frame 5.

In this case, the inner shield 7 is attached to the flange 5a portion of the mask frame 5 so that the inner shield 7 and the holes 7a and 5b respectively formed in the flange 5a coincide with each other. The inner shield 7 is arranged on the flange 5a, and then is made as the fastener 9 is inserted into both of the holes 7a and 5b.

That is, the fastener 9 is coupled in the above state, and then exerts a predetermined elastic force on the inner shield 7 and the flange 5a, and by these elastic forces, the inner shield 7 The mask frame 5 can be stably fixed.

FIG. 10 is a perspective view of the fastener 9 described above. In general, the fastener 9 is bent in a substantially V-shape to form a first elastic bent portion 9a. Each side extending in both lateral directions of the section 1 is bent inward at a predetermined position to form the first bent section 9b, and is further diverted at a predetermined interval to the second bent section 9c. ), The show rate 9d is formed.

In addition, the fastener 9 is completely folded so that the second elastic bent portion 9e formed by bending each side extending from the second bent portion 9c back outward from a predetermined position does not retain its own elastic force. The grip portion 9f is formed, and the end portion of the grip portion 9f is bent outward to form the third elastic bent portion 9g and the crimped portion 9h integrally.

That is, the fastener 20 has a kind of tweezers (pincette) formed by symmetrical shape of the two parts, which are split from both sides from the upper part and symmetrically, as shown in the drawings. .

First, the fastener 20 has an elastic portion 20b that is bent to both sides of the bent portion 20a positioned at the uppermost side. In this case, the two elastic portions 20b serve as a portion to allow the fastener 20 to have an elastic force.

At one end of both elastic portions 20b, a handle portion 20c is formed to be bent and extended to allow a user to hold and use the fastener 20. At this time, both handle portions 20c are formed. ) Is formed in a curved shape toward the inside facing the user so as to easily hold and press it.

In addition, from one end of the handle portion (20c) is formed bent at a predetermined angle so that the joints (20d, 20'd) having a predetermined length is also disposed toward the inner side facing each other, the two joints From one side end of 20d and 20'd, an internal angle reduction means for reducing the internal angle θ formed by both elastic portions 20a is formed.

This cabinet reduction means serves to elastically reduce the above-described cabinet (θ) according to the pressing state of the fastener by the user, the configuration of the first, extending from one side end of one side joint portion 20d Support portion 20e is included.

The support portion 20e is a portion that is bent from one end of the joint portion 20d so as to be disposed in an upright state, and a hole portion 200e having a predetermined size is described in the inner portion of the joint portion 20d and the back. It extends through a portion of the insertion portion 20i to be formed therethrough.

In addition, as another configuration of the reduction means, the first inclined portion 20f formed by being protruded from one side end portion of the other one side joint portion 20'd and bent again from the first inclined portion 20f is formed. 20g of straight lines arrange | positioned in an upright state, and the 2nd inclination part 20h formed by bending at a predetermined angle again from this straight line 20g are included.

Here, the first inclined portion 20f, the straight portion 20g, and the second inclined portion 20h are formed to have a width smaller than the width of the hole portion 200e. This is to be inserted into the hole 200e.

As the reduction means formed as described above, an insertion portion 20i is formed to extend. Here, the insertion portion 20i will be described later, but is inserted into the insertion hole formed in the fastening component so that the fastener 20 can function substantially, which is the support portion 20e and the second inclination. It is formed to be bent to face toward the outside facing from the portion 20h and is formed of a free end that is bent to face toward the inside facing again at a predetermined position.

Accordingly, the fastener 20 formed as described above performs the following function to couple components such as a mask frame and an inner shield to each other.

2 to 5 are diagrams for explaining the operation of the fastener 20. First, the fastener 20 is, for example, when the cathode ray tube is manufactured, for example, the mask frame 30 and the inner shield 40 are formed. When each of the coupling hole portions 30a and 40a coincide with each other to form a coupling state, the insertion portion 20i is moved to the hole portions 30a and 40a while being positioned above the hole portions 30a and 40a. By inserting a predetermined elastic force to the mask frame 30 and the inner shield 40 is fixed to each other.

2 is an initial state in which the fastener 20 is positioned above the hole portions 30a and 40a in order to achieve the above-described action, at which time an internal angle formed between the elastic portions 20b of the fastener 20 is shown. Let θ1 be.

In this state, when the user grabs the handle 20c and presses the fastener 20 in the direction of the arrow shown in the drawing, the fastener 20 is the cabinet as shown in FIG. 3. Is reduced from the first θ1 to θ2, thereby bringing the two inserting portions 20i closer to each other.

Then, the inserting portions 20i may attempt to enter the hole portions 30a and 40a by the structural state. In this case, the inserting portions 20i may be inserted into the hole portions 30a, When it is difficult to smoothly insert into 40a), the user presses the fastener 20 further until the internal angle is maintained at θ3 as shown in FIG.

Then, at this time, the both inserting portion 20i can be closer than the above state, which is the first and second inclined portion (20g) including the straight portion (20g) in the process of reducing the angle to θ3 ( 20f and 20h are possible by temporarily inserting into the hole 200e.

In this way, the two insertion portions 20i can be more easily inserted without being disturbed by the two hole portions 30a and 40a, thereby allowing the user to release their hands from the two handle portions 20c. When the pressurized state of the fastener 20 is terminated, the fastener 20 is elastically converted as shown in FIG. 5 while the support portion 20e and the straight portion 20g are formed in the hole portion 30a. The mask frame 30 and the inner shield 40 are formed in close contact with the inner surfaces of the mask frame 30 and the inner shield 40 on which the mask frame 30 is formed, and then the mask frame 30 and the inner shield 40 are fixed.

6 to 7 illustrate modified examples in which the fastener 20 has the above-described structure, and the shape of the handle part 20c is different.

That is, FIG. 6 is a perspective view showing the fastener 20 provided with the handle portion 20c in a bent form rather than in a curved form, as shown in the drawing, wherein the handle portion 20c faces toward the inner side facing each other. It is provided in a form bent at least one or more times. In addition, FIG. 7 illustrates the fastener 20 provided in a flat state in which the handle part 20c is not curved or bent.

As such, in this embodiment, the fastener 20 may be provided by forming a handle part 20c in various forms.

8 is a perspective view illustrating a fastener according to another embodiment of the present invention. The fastener 50 according to this embodiment has its overall shape as a normal fastener.

In other words, the fastener 50 has a typical fastener shape formed by dividing into two around the lower part based on the drawings. Specifically, the fastener 50 includes elastic parts 50b and 50'b that are bent at a predetermined angle with respect to the bent part 50a. By extending one side end of 50b, 50'b, an internal angle reduction means is formed so as to reduce the internal angle θ formed by the elastic members 50b, 50'b.

In the present embodiment, the reduction means is bent from one side end of the one side elastic portion 50b toward the bent portion 50a and then bent outward from the bent portion 50a at a predetermined position. Of course, the support portion 50c having a hole 500c having a predetermined size therein is included.

In addition, the reduction means includes a first protrusion 50d formed to be bent inward toward the bent portion 50a from one side end of the other elastic portion 50'b, and from one end of the protrusion 50d. The second protrusion 50e which is bent in the outward direction deviating from the bent portion 50a is included.

Here, the first protrusion 50d and the second protrusion 50e are formed to have a width smaller than the width of the hole 500c, and in some cases, in other words, depending on the degree of change of the inner angle θ. It is inserted into the hole 500c.

On the other hand, the handle portion 50f extending from one side end of the support portion 50c and one side end of the second protrusion 50e substantially allows the user to hold and use the fastener 50, In this embodiment, the handle portion 50f includes a first joint portion 500f that is formed to be inclined outwardly from the bent portion 50a at the support portion 40c and the second protrusion portion 50e. It comprises a second joint portion 502f that is bent to abut one surface of the first joint portion 500f at one end of the first joint portion 500f.

In addition, the fastener 50 is formed by bending the crimping portion 50g disposed in an outward direction away from the bent portion 50a to one end of the second joint portion 502f in the handle portion 50f. The pressing portion (50g) is in close contact with the surface of the fastening component for fixing the fastener 50 serves to ensure that the fastener 50 has a stable posture.

Thus, the fastener 50 formed as described above, when the user grasps both the handle portion 50f and presses the handle portion 50f so as to be close to each other, the inner angle θ decreases and the elastic portion ( 50b and 50'b are also close to each other, and the elastic portions 50b and 50'b are larger in width than the width of the insertion hole formed in the fastening component such as the mask frame or the inner shield. If the portions of the portions 50b and 50'b are difficult to easily enter into the holes of the fastening parts, the user may fasten the fasteners to the extent that the first and second protrusions 50d and 50e are inserted into the holes 500c. Further pressurize the 50.

Then, the inner angle θ is further reduced according to the operation, so that both elastic portions 50b and 50'b are closer to each other than the above-described state, so that the width between the two portions can be further reduced. 50 is to be able to secure the fastening part while easily inserting the elastic portion (50b, 50'b) portion into the hole of the fastening part.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made within the scope of the utility model registration claims and the detailed description of the invention and the scope of the accompanying drawings. This also belongs to the scope of the present invention.
