Display interface dustproof structure

Abstract

This utility model relates to the field of interface dustproof technology, specifically a dustproof structure for a display interface, including a display and a signal port located at the bottom of the back of the display. The key feature is that a storage box is fixedly connected to the back of the display near the top of the signal port. The advantages of this utility model are: by using a push spring to push the dust cover downwards and press against the sealing flange, the signal port can be effectively sealed. Simultaneously, during insertion, simply align the plug with the push handle and press down, causing the slider to slide down. Pulling the cord lifts the dust cover, aligning the plug with the signal port, and then inserting it. This eliminates the need for one hand to lift and the other to insert, allowing for easy one-handed operation. Furthermore, the sealing ring on one side of the dust cover and the sealing gasket on the top surface of the sealing flange effectively seal any gaps around the signal port, improving the dustproof sealing effect.

Description

Technical Field

[0001] This utility model relates to the field of interface dustproof technology, and in particular to a dustproof structure for a display interface. Background Technology

[0002] In the information age, monitors, as a crucial window for human-computer interaction, are widely used in various fields such as computers, smart TVs, and industrial control. With the continuous development of display technology, the types of monitor interfaces have become increasingly diverse, including HDMI, USB, VGA, and DP. These interfaces undertake key functions such as data transmission and video signal input. However, because monitor interfaces are constantly exposed to the external environment, they are highly susceptible to contaminants such as dust, particulate matter, and hair.

[0003] When dust enters the monitor interface, it forms an insulating layer on the surface of the interface contacts, leading to unstable signal transmission and problems such as image flickering and data loss. On the other hand, accumulated dust may also absorb moisture from the air, causing oxidation and corrosion of the interface metal contacts, severely shortening the monitor's lifespan, and even causing short circuits and posing safety hazards.

[0004] Currently, there are two main methods for dust prevention of monitor interfaces on the market. One is to use rubber plugs or plastic caps for physical sealing. Although this method can play a certain role in dust prevention, frequent plugging and unplugging can easily cause the dust plugs to be lost and may cause wear and tear on the interface. The other method is to set a flip-up dust cover inside the monitor casing, but the dust cover needs to be manually flipped up every time it is inserted, which is inconvenient. Utility Model Content
