USB interface cover

The present invention relates to a USB interface protective cover.

The use of computers and information-related devices is becoming more and more popular, and its functions are rapidly expanding and integrating. Therefore, many peripheral devices have become an important part of computer systems and their applications, such as printers, scanners, screens, and external hard drives. Dish and so on. These peripheral devices must be connected to each other using various types of wiring and connectors. There are many types of these connectors, and the more common ones are Serialpoft, Parallel, Port, SCSIPort, and PS2. However, because there are too many types to increase the complexity and cost of the system, more importantly, the performance is gradually unable to meet the demand. In recent years, the industry has popularized a standard specification connector, also known as USB (Universal Serial Bus) connector, to replace the current messy situation. In addition, it can greatly improve the performance of transmission data to meet the requirements of high-speed transmission. .

The USB device of the peripheral device such as MP3 and U disk has one end built in and connected to the internal circuit, and the other end is exposed to be connected to the computer. The exposed end is generally called USB interface, because the USB interface is easy to enter dust, moisture, etc. Affects the connection performance, therefore, the USB interface is generally provided with a protective cover. The conventional protective cover is generally a rectangular cover body, and the rectangular cover body is directly sleeved on the USB interface. However, when the protective cover is pulled out, the protective cover is clamped by a user's finger to be pulled out, and the structure is not It is convenient to protect the cover from the USB interface; in addition, due to the relatively complicated structure inside the rectangular cover, Molding such a protective cover is relatively difficult.

In view of this, it is necessary to provide a USB interface protection cover that is easy to handle and easy to manufacture.

A USB interface protection cover includes a cover head and a cover body connected to the cover head, the cover head is provided with a hanging hole at one end, and a hook is protruded from an end surface of the other end, and the cover body has a sleeve structure, and A latch is formed on the inner side wall, and the cover is assembled with the cover by the hook and the snap to form the USB interface protection cover.

Compared with the prior art, the USB interface protection cover is formed by assembling a cover head and a cover body. One end of the cover head is formed with a hanging hole. When the protective cover is attached, one end of the hanging hole can be easily grasped by the user. Therefore, the USB interface protection cover can be conveniently loaded from the USB interface; and the hanging hole can also be mounted with a charm to make the USB interface protection cover look beautiful; the USB interface protection cover is formed by separately forming the cover head and the cover After the body is then assembled, the mold that forms the protective cover at a time can simplify the mold internal model and is easy to manufacture.
