Abstract

The present invention relates to a clamping device (CLAMP) for mounting and fixing the deflection yoke (DY) and the convergence adjusting device (CPM), which are parts of the CRT, to the NECK part of the CRT.

In the conventional method, when clamping bolts, the clamping ends of the clamps act on each other, so the tensile force is concentrated in a specific part of the clamp, and the end of the clamp is twisted in the tightening direction. Breaking or cracking occurs in structures that are tightened while falling down (Brown Tube Neck: Glass Tube), and clamps that have been tightened once have a problem that cannot be reused.

The present invention to improve this,

When the clamp end is tightened with bolts, the structure can be completely solved by mutually solving by restraining the tension force concentrated through the clamp through the center of the clamp facing each other. It is to solve the problem of failure, crack and clamp reuse.

Description

Insertion clamps {INSERT CLAMP}

1 is a view showing the role of the clamp (CLAMP) for fixing the deflection yoke (DY-6) and the convergence adjusting device (CPM-7) of the rear neck (5) of the CRT.

In general, the clamp (CLAMP) is composed of a band surrounding the structure (FIG. 1-3) and a bolt tightening the band (FIG. 4-4). When passing through and tightening, the end portion 16 of the band 12 penetrates the opening 17 and transmits the concentration of force in parallel as shown in FIGS. By generating an even tension of the structure can solve the problem of cracking, breakage and clamping of the CRT neck (5) structure. By the way, the existing clamp has the same shape as that of FIG. As a result of tension being concentrated in a specific part (figure 3) inside the band, it is a factor that causes breakage or cracking of the CRT 5, and deformation of both ends of the band and thread breakage when tightening once Problems such as non-reuse can occur due to the lowering of productivity and the cost of materials being discarded, resulting in a cost increase factor.

Existing clamps have many structural problems due to the concentration of force when tightening the banding. Therefore, to solve this problem, the clamps are evenly inserted into the band in the form of an insert clamp that prevents the concentration of the force when tightening the banding. The purpose is to create a structure in which a tension acts.

Insert clamp of the present invention (INSERT CLAMP) is basically composed of a band 12 and the bolt (4), 4, 5, 6 as shown in the bolt 4 through the threaded portion 18 through the band ( 12) The band end portion 16 is configured to pass through the opening 17 during tightening.

Existing clamps (3rd) break the CRT (5) when tightening CRTs, and can not be reused due to deformation of both ends of the band and thread breakage when tightening once, resulting in reduced productivity and material loss. Although bringing the cost increase factor, the insert clamp of the present invention is designed to prevent the loss caused by product damage by solving the structural method, to secure competitiveness and reduce cost by reusing the band. Has the effect of.
