Description

Dust-proof structure

technical field

The invention relates to a dust-proof structure, in particular to a dust-proof structure for an input/output unit opening.

Background technique

With the continuous advancement of technology, portable electronic devices have become an indispensable part of many people's lives. For example, notebook computers, mobile phones, personal digital assistants (PersonalDigital Assistant, PDA), etc. These portable electronic devices are usually equipped with input/output units such as electrical connectors and card readers for connecting cables or memory cards to transmit electronic information. Taking electrical connectors as an example, in order to meet different usage requirements, the transmission specifications of electrical connectors have developed a variety of specifications, and are constantly being updated. Currently common transmission specifications include USB 2.0, IEEE 1394, eSATA, etc., while USB 3.0 is a new specification developed recently, and its future potential is promising.

Because of these electrical connectors, there may not always be a cable or memory card plugged into the card reader. Dust can easily enter the opening of the electrical connector or the card reader when the cable or the memory card is pulled out, increasing the chances of a short circuit or poor contact in the electrical connector or the card reader. Therefore, it is often necessary to use additional partition plastic sleeves, rubber (Rubber) soft covers or dummy (dummy) cards to be configured at the opening of the I/O unit to prevent dust or insects from entering.

However, such dust-proofing methods are often done manually, which increases additional troubles for consumers and users and makes these radiant portable electronic devices less attractive. In addition, the additionally assembled fake cards are often lost after the user takes them down, which also loses the original dust-proof effect.
