(5) embodiment
Below, describe concrete structure of the present invention in detail with reference to figure 2-Fig. 3.
Wherein Fig. 2 is the sectional drawing that the image mask structure of display constructed in accordance is fixed on the image shade state of cathode ray tube.
Wherein Fig. 3 is the schematic drawing of the state of image mask structure according to the display of the present invention image shade that is fixed in the neck that is clipped in cathode ray tube.
Structure of the present invention is cathode ray tube 3 and the cathode ray tube neck 8 that twines the image end 7 of display and be incorporated into video display.
Structure of the present invention is described in detail as follows.
Described cathode ray tube neck 8 is inserted on the socket of the image end group plate 11 that is positioned at described image end 7; Image shade 6 twines the above-mentioned image end 7 that comprises image end group plate 11, forms with above-mentioned cathode ray tube neck 8 connects in the central authorities of image shade 6 and combines mouth 12.
In order to make the stable secure bond of above-mentioned image end 7 at described cathode ray tube neck 8, at above-mentioned image end 7 one sides fixed metal plate 19 is arranged, fixed metal plate 19 has the image end joint portion that combines with described image end 7; The neck joint portion 18 that combines with described cathode ray tube neck 8 (connecting the cylindrical projection position of fixed metal plate 19), 28 (cylinder positions), 29 (projections).
Connect the neck joint portion 18,28,29 of described conductivity foam washer 16 and described fixed metal plate 19, the periphery that is fixed in the cathode ray tube neck 8 on the socket of image end group plate 11 of described image end 7 in insertion is twined conductive rubber 13 with certain-length, and this conductive rubber 13 connects the combination mouth 12 of the image end 7 that contact with above-mentioned foam washer 16.
Be wound on 18,28,29 outsides, neck joint portion of described fixed metal plate 19, to clamp the metal retainer ring 20 of the neck joint portion 18 (cylindrical projection position), 28 (cylinder positions), 29 (projections) and the above-mentioned cathode ray tube neck 8 that link said fixing metallic plate 19.
Here, above-mentioned image shade 6 is the center with the axis of cathode ray tube neck 8, the periphery at angle in the intercepting two, and formation is shaken position 21, two inferior horns and is formed the first perforation position 22 respectively.
At the flange position 15 of above-mentioned foam washer 16 and the crooked drum type terminal 14 of flange position 15 beginning from then on, forming a plurality of is center and cut-out line 23 with certain angle spacing with the axis.
The drum shape terminal position 14 of above-mentioned foam washer 16 is adjacent to the fixing in conjunction with mouth 12 of image shade 6.In addition, abut against each other according to the drum shape terminal position 14 of above-mentioned conductive rubber 13 and above-mentioned foam washer 16 and to contact, sealing that can be perfect is from the electromagnetic wave of image end 7 emissions.Here, above-mentioned foam washer 16 is to switch on.
The structure that above-mentioned fixed metal plate 19 has the image end joint portion that combines with described image end 7 is: the supporter 17 of fixed metal plate 19 be corresponding above-mentioned image shade 6 shake position 21, two corners at upside form suspension hook position 24 respectively, form first of corresponding above-mentioned image shade 6 in two corners of downside and connect 22, possess the outstanding terminal position 27 at the second perforation position 26.
Moreover the cylindrical projection position 18 of said fixing metallic plate 19 constitutes with a plurality of cylinders position 28 that a determining deviation forms, and in above-mentioned cylinder position 28, forms projection 29 at least at two places.
Above-mentioned metal retainer ring 20 is the projections 29 at corresponding above-mentioned cylinder position 28, forms plural at least in conjunction with a mouthful 12a respectively in the edge.
According to above-mentioned metal retainer ring 20 conductive rubber 13 of the cylindrical projection position 18 of fixed metal plate 19 and cathode ray tube neck 8 sides is abutted against each other fixingly thereupon, when cathode ray tube 3 is impacted or shakes, also can closely keep the bonding state between the outstanding position 18 of above-mentioned conductive rubber 13 and drum shape.
Below to according to the present invention, and the cohesive process of the image mask structure of the display of manufacturing as described above describes.
Fig. 4 is the exploded view of main structural components of the image mask structure of display constructed in accordance.
At first as shown in Figure 4, on the central shaft of the front of image shade 6 in conjunction with mouth 12, behind the central axis to the drum shape terminal position 14 of last foam washer 16, the front side that image shades 6 are inserted at the drum type terminal position 14 of above-mentioned foam washer 16 is in conjunction with 12 li in mouth, and clamps.
Then, after twining conductive rubber 13 around the cathode ray tube neck 8, put the outstanding position 18 of drum shape of fixed metal plate 19, and make it can center on conductive rubber 13 peripheries.
Then, on two projections 29 that form at the cylinder position 28 of this cylindrical projection position 18, sandwich respectively metal retainer ring 20 in conjunction with behind mouthful 12a, use screw and nut to link two terminals of metal retainer ring 20.
This moment, the conductive rubber 13 of above-mentioned cathode ray tube 3 and the cylindrical projection position 18 of fixed metal plate 19 abutted against each other according to the clamping action of above-mentioned metal retainer ring 20.
After earlier second of the outstanding terminal 27 of the downside corner portions of said fixing metallic plate 19 being connected the downside first perforation position 22 of the above-mentioned image shade 6 of position 26 alignings then, above-mentioned second connect position 26 be bent upwards position 25, insert first respectively and connect position 22.The position 25 that is bent upwards that connects position 26 this moment above-mentioned second is the edges that are adjacent to the above-mentioned first perforation position 22 according to elasticity.
Then, the upside of the above-mentioned image shade 6 of each suspension hook 24 insertion of the upside corner portions of said fixing metallic plate 19 formation being shaken position 21 gets final product.This moment, the degree of depth of cathode ray tube neck 8 parts was inserted on the socket perpendicular to the image end group plate 11 in the image shade 6.
According to so constructing, the conductive rubber 13 of cathode ray tube 3 necks 8 abuts against each other with the drum type terminal position 14 of the foam washer of the combination mouth 12 that is clipped in above-mentioned image shade 6, the electromagnetic wave of image end 7 generations of the disconnected cathode ray tube 3 of envelope that can be perfect.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
