Background technique

With the vigorous development of multimedia information, various electronic devices such as notebook computers, personal digital assistants (PDA), music players, video players and other products have gradually become indispensable to people's life and work. important tool. For the input, output and expansion of various information, sound and video, electronic devices usually include various connectors, such as USB connectors, memory card connectors, earphone connectors, etc. The transmission openings of these connectors are if Without the protection of the electronic product casing, it is directly exposed to the environment, and it is easy for dust and moisture to enter, which will affect the service life of the connector.

In the current application of electronic devices, two methods are often used to achieve the dust-proof function of the connector. One is the dust-proof component designed to be incorporated into the body shell, and the position of the body shell corresponding to the above-mentioned connector is designed to be opened. With closed parts to achieve the purpose of dust. Another way is to attach a single or multiple additional dust-proof parts to the shell of the original body. When the connector is not in use, the dust-proof parts can be used to cover the connector, and the dust-proof parts can be replaced when needed. Remove to expose the connector. The problem with the first case design method is that it increases the number of components in the case design of electronic products, increasing the complexity of the design and the manufacturing cost, while the second method of additionally attaching a dust cover may affect the appearance of the product With the simple design, the user's operation convenience is also compromised. Therefore, how to design a new connector dust-proof structure to solve the problem of dust and moisture ingress without affecting the convenience of use and the beauty of the overall body is an important issue for relevant production designers.
