[0026] As shown in Figures 1-3 The indicator light 9 display device of the application is installed on the cabinet door plate 1, and the indicator light 9 display device comprises an indicator light 9 mounting plate, a plurality of indicator lights 9 mounted on the indicator light 9 mounting plate, and a light guide sleeve 8, wherein the light guide sleeve 8 comprises a plurality of sleeves 82, and the indicator lights 9 are respectively located in the sleeves 82. The upper side of the light guide sleeve 8 is covered with a conductive glass 4, and the conductive glass 4 is made of ITO coated conductive glass 4 material. In a preferred embodiment, the light guide sleeve 8 is made of black engineering plastic, and the light guide sleeve 8 has a plate-shaped structure and is provided with a plurality of first mounting holes 81, and the lower surface of the first mounting hole 81 extends downward to form the sleeve 82. The indicator light 9 is located at the bottom of the sleeve 82 and is a distance away from the upper surface of the sleeve 82. The light guide sleeve 8 is used to collect the light of the indicator light 9 and effectively avoid the mutual interference between the plurality of indicator lights 9.
[0027] As shown in Figures 4-6 The indicator light 9 display device further comprises a pressing plate 7 and a door plate cushion block 3. The pressing plate 7 is composed of a central recessed area 72 and a peripheral edge area 73. The recessed area 72 is located at the central part of the pressing plate 7 and has a downward recessed shape, and a plurality of second mounting holes 71 are formed in the bottom of the recessed area 72. The light guide sleeve 8 is accommodated in the recessed area 72, and each sleeve 82 of the light guide sleeve 8 is correspondingly installed in the second mounting hole 71 from top to bottom. The conductive glass 4 is also accommodated in the recessed area 72, and the upper surface of the conductive glass 4 is flush with the upper surface of the edge area 73. The pressing plate 7 is made of a metal conductive material or has a conductive coating on the surface of the engineering plastic.
[0028] The door plate cushion block 3 has a frame-shaped structure, and the inner side thereof covers the edge of the conductive glass 4, and the outer side edge covers the upper surface of the edge area 73 of the pressing plate 7. The edge area 73 of the pressing plate 7 is fixed on the door plate cushion block 3 by screws. The upper surface of the door plate cushion block 3 is fixed on the cabinet door plate 1 by welding.
[0029] A first rubber pad 5 is laid around the edge of the conductive glass 4. This rubber pad does not cover the display area of the conductive glass 4, but is only set around its edge, and the edge of the first rubber pad 5 extends beyond the edge of the conductive glass 4. This allows the first rubber pad 5 to not only achieve a sealed connection between the door panel pad 3 and the conductive glass 4, but also, the part extending beyond the edge of the conductive glass 4, achieves a seal between the door panel pad 3 and the pressure plate 7, while also serving a vibration damping function.
[0030] A second rubber pad 6 is provided on the lower surface of the conductive glass 4. The second rubber pad 6 has multiple light-transmitting areas corresponding to the first mounting holes 81. The second rubber pad 6 ensures that the upper surface of the light guide sleeve 8 is tightly fitted to the conductive glass 4, achieving a sealing and electromagnetic shielding effect.
[0031] The chassis door panel 1 has multiple light-transmitting holes, which are aligned with the position of the indicator lights 9. A closed and conductive cavity is formed by the door panel pad 3, conductive glass 4, first rubber pad 5, and second rubber pad 6. This cavity can not only effectively block the penetration of electromagnetic waves and achieve electromagnetic shielding, but also prevent external dust, moisture, etc. from entering the chassis, thus achieving airtightness.
[0032] A display film 2, which is a frosted PC film, is covered over the light-transmitting holes of the chassis door panel 1. The back of the display film 2 is adhered to the chassis door panel 1 with adhesive. The frosted material of the display film 2 prevents direct visual observation of the detailed internal structure of the chassis from the outside of the chassis door panel 1. In addition, the frosted material can also change the refraction of light, thus avoiding discomfort caused by excessively strong light.
[0033] The vertical direction described in this application is attached. Figure 2 and 3 Taking the direction shown as reference, the door panel pad 3 covers the pressure plate 7 and the conductive glass 4.
