The present invention relates to a cover filter binding device for a monitor, and more particularly, to improve the cover filter binding device for blocking harmful waves flowing out of the monitor, thereby maintaining the transport range of the cover filter detachable to the front case in the shortest distance. At the same time, the present invention relates to a cover filter binding device for a monitor, which prevents the cover filter from being easily separated and reinforces and continuously maintains the grounding force of the ground terminal.

In general, a monitor that examines and analyzes a process of collecting or processing information includes a monitor case which protects by incorporating a cathode ray tube showing a moving picture on a screen by largely converting an electrical signal into a change of light, and preventing harmful waves from leaking out of the monitor. The cover filter and the stand to adjust the monitor to the user's working position.

In the conventional cover filter binder, as shown in FIGS. 1 to 3, a band 10a and a funnel 10b are coupled to a boundary portion of the cathode ray tube 10 formed with a band. (11) is mounted, and lugs (12) formed with screw holes are fixed to the corners of the four bands (11) on each side of the band (11) by welding or the like, and the cathode ray tube (10) is fixed. The rear end is equipped with a deflection yoke (not shown) for deflecting the electron beam scanned by the electron gun (not shown).

In addition, in front of the front case 13 to which the cathode ray tube 10 is fixed by a plurality of fixing screws, a binding protrusion 15 having guide rails 14 formed on both sides thereof protrudes, and the guide rails 14 A substantially rectangular spring insertion hole 14a is formed in the center, and the chassis ground terminal 16 is fixed to the outside of the cathode ray tube 10.

In addition, a cover 20 for blocking harmful waves of the monitor is attached to the binding protrusion 15 protruding forward of the front case 13, and fastening ribs having insertion holes 21 a formed on both sides of the cover 20. 21) is attached, the c-shaped ground terminal 22 is mounted in the center of the cover 20 in the upper, lower, left and right directions, respectively, the filter (23) on the ground terminal (22) Is fitted without flow.

In addition, the insertion hole 21a of the binding rib 21 has a ground spring 24 having a ground portion 24a bent at a predetermined length at one end to be grounded with the chassis ground terminal 16. One end of the spring 24 is inserted into a fixing hole 25a formed in the filter guide portion 25 mounted inside the cover 20 to be grounded on one surface of the bead terminal 22, and to ground the filter 23. The filter ground part 26 is provided in the terminal 22.

In the conventional cover filter binding device configured as described above, the cathode screw tube 10 is brought into contact with the inner surface of the front case 13 by tightening a fixing screw in the screw hole of the lug 12 fixed to each corner of the band 11. In the fixed state, the front case 13 and the rear case 17 are combined by a suitable method such as a fastening screw to protect the cathode ray tube 10, and then to the binding protrusion 15 protruding in front of the front case 13. The cover 20 to which the filter 23 is fixed is attached from top to bottom.

At this time, the filter 23 is inserted into the ground terminal 22 mounted in the up, down and left and right directions at the center of the cover 20 so as not to flow, and the fastening ribs 21 are attached to both sides of the cover 20. One end is inserted into the fixing hole (25a) of the filter guide portion 25 in the insertion hole 21a of the ground spring 24 having the ground portion 24a grounded on one surface of the ground terminal 22. When the cover 20 is fastened from the top to the bottom along the guide rail 14 of the fastening protrusion 15, that is, a button type, the ground part protruding from the insertion hole 21a of the fastening rib 21 to the outside ( 24a) is inserted into the spring insertion hole 14a formed in the center of the guide rail 14, and is grounded to the chassis ground terminal 16 mounted on the outside of the cathode ray tube 10 to prevent harmful waves generated from the monitor. ) Is delivered to the filter 23 to block.

However, in the conventional cover filter binding device configured as described above, since the harmful waves generated in the monitor are transmitted to the filter fixed to the ground terminal of the cover by the ground spring grounded on the chassis ground terminal, the chassis is elastically deformed as the ground spring is elastically deformed. The grounding effect can not be maintained continuously with the ground terminal, and the grounding effect is lowered, and it is fastened to the guide rail of the front case by using fastening ribs attached to both sides of the cover, which requires a lot of space in the upper direction. There is no separate fastener to prevent the separation, there was a problem that the loss of the spring, etc. when the cover filter is attached.

In addition, since the cover filter is easily detached in front of the front case, when the monitor is inverted during transport, the mounting position of the cover filter is changed, as well as easily damaged, thereby lowering the quality of the product.

The present invention is to solve the problems as described above, the object of the present invention by fixing a cathode ray tube to protect the front case, and by attaching a plurality of fastening members to the cover filter to block harmful waves generated by the monitor In addition, it maintains the grounding power of the filter to which harmful waves are transmitted, and also reduces the space when attaching the cover, facilitates the attachment and detachment of the cover filter, and at the same time, it is not easily separated. The present invention provides a cover filter fixing device for a monitor that can prevent a change in the mounting position and prevent damage to improve product quality.

A feature of the present invention for achieving the above object is that the cathode ray tube formed by combining the panel and the funnel is fixed in the front case and the rear case coupled by the fastening member, and the harmful wave generated in the monitor in front of the front case.
