Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a connecting clip, and more particularly to a connecting clip that can easily connect an inner shield of a cathode ray tube (CRT) and a frame and can effectively prevent separation after mounting.

[0002]

[Prior art]

 Generally, a frame for supporting the shadow mask is arranged inside the panel of the cathode ray tube, and an inner shield for preventing the influence of the earth magnetic field from outside the shadow mask is attached to the frame.

Since the inner shield and the frame have a structure that cannot be integrally molded, an operator uses a connecting clip to assemble the two separately after assembling them separately.

FIG. 3 is a perspective view of such a conventional coupling clip.

Referring to FIG. 3, the connecting clip C is bent at a substantially middle portion into a V shape to form a first elastic bent portion 1 at its apex, and from the first elastic bent portion 1. Each member extended to both sides is bent inward at a predetermined position to form first bent portions 2 and 2, and further upward at a position spaced apart from the first bent portions 2 and 2 by a predetermined distance. The shoulders 4 and 4 are formed by forming a second bent portion 3 and 3 by bending toward.

Further, the respective members extending from the second bent portions 3 and 3 are bent outward again at predetermined positions to form the second elastic bent portions 5 and 5. However, in the second elastic bent portions 5 and 5, the respective members are completely bent, and the grip portions 6 are formed so that the bent portions do not have an elastic force.

The ends of the grips 6, 6 are finally bent outward to integrally form the third elastic bent parts 7, 7 and the crimp parts 8, 8.

In such a conventional coupling clip C, the shoulders 4 and 4 receive the elastic force of the first elastic bending portion 1, and the crimping portions 8 and 8 have the second bending portions 3 and 3 and the third elastic bending portion. It receives the elastic force of the curved parts 7, 7.

Therefore, using the conventional coupling clip C, as shown in FIG. 4, the first elastic bending of the coupling clip C is formed in the coupling holes H formed in both the inner shield I and the frame F. When the portion 1 is inserted, the shoulders 4 and 4 exert a horizontal force on the lower surface of the frame F by the elastic force received from the first elastic bending portion 1.

At the same time, the crimping portions 8, 8 formed at the ends of the grip portions 6, 6 come into contact with the surface (upper surface) of the inner shield I, so that the second bending portions 3, 3 and the third elastic folding portion are formed. Due to the elastic force received from the curved portions 7 and 7, the compression portions 8 and 8 apply a vertical force.

As a result, in the connecting clip C, the shoulders 4 and 4 are hooked on the lower surface of the frame F, and the crimping portions 8 and 8 are kept crimped to the surface of the inner shield I. Both the shield I and the frame F will be connected.

[0012]

[Problems to be solved by the device]

 However, in such a conventional coupling clip C, the shoulder 4 and the crimping portion must be formed so that the separation distance between the shoulder 4 and the crimping portion 8 shown in FIG. 3 is not a predetermined amount at the time of manufacturing. Since the elastic force received by 8 and 8 is not sufficiently exerted, there is a problem that there is a high possibility that the connecting clip C will be easily detached after being attached to the binding hole H.

In addition, in such a conventional coupling clip C, the first elastic bending portion 1 is inserted into the binding hole H while the grip portions 6 are used as grips and both of the grip portions 6 are contracted inward. Since they are attached by being attached, both the gripping portions 6 must be manually picked up and applied with force at the time of joining work, which causes a problem of inconvenience in use.

Therefore, the present invention has been made in view of the above problems, and the work of connecting the inner shield and the frame can be easily performed, and the detachment after the mounting can be effectively prevented. An object is to provide a coupling clip that can be used.
