Abstract

The present invention relates to a sliding apparatus that can selectively block the exposure to the exterior of various terminal parts including USB terminals, charging terminals, etc., which are formed on its sliding part, by causing the sliding part to be selectively pulled in or pushed out with respect to the body, depending upon the need of the user.

Description

Sliding device

The present invention relates to a sliding device, and more particularly, to allow the sliding portion to be selectively drawn out and received from the main body according to the user's needs, so that various terminal portions such as a USB terminal and a charging terminal formed on the sliding portion are exposed to the outside. It relates to a sliding device to selectively block.

In general, USB (Universal Serial Bus) refers to a bus standard for connecting a computer and a peripheral device. Such USB refers to a variety of devices such as personal computers, digital cameras, mobile phones, MP3, PMP, PDAs, and memory devices. It is used for.

Among them, the USB memory device is connected to a USB port of a computer, and has a flash memory or a small hard disk therein for reading pre-stored data or writing arbitrary data through data transmission at a predetermined speed. Compared to devices, large files can be moved, communication speed is fast, and the plug and play method is not only simple to use, but also a compact and portable stick type. It is used as a portable storage device of various external devices such as a digital portable terminal.

As shown in FIG. 1, the conventional USB memory device includes a main body 100 having a built-in flash memory and having a USB terminal 110 formed at one side thereof, and a protective cap 120 covering the main body 100. do. And the other side of the main body 100, the connection portion 115 is formed so that the key ring or necklace string is connected.

In the conventional USB memory device configured as described above, the protective cap 120 should be removed every time it is used. The protective cap 120 is a small component that is completely separated from the main body 100, and thus is often lost. If the protective cap 120 is lost, not only does not look good, but also because the USB terminal 110 is exposed to the outside when carrying, foreign matter is inserted or damage caused by external shock, There was a problem that the connection between the USB terminal 110 and various external devices is impossible.
