Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug module of an external device for a portable terminal and an external device for a portable terminal having the plug module,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an external device mounted on a portable terminal by inserting a plug into a socket provided in a portable terminal, and more particularly to a plug module provided in the external device and an external device including the plug module.

A portable terminal, such as a smart phone, couples or directly couples to various external devices. The most common external devices include a charger that connects with a cable, and a USB memory that connects directly to a USB plug. However, any type of external device is not electrically connected until a plug is inserted into a socket provided in the portable terminal. The same is true of cable.

Many conventional external devices use a cable-based approach. As the size of the external device increases, there is a part where the direct connection is structurally insecure, and the portability of the portable terminal is also significantly restricted. However, since the external device and the portable terminal are separated from each other through a cable, the portability of the portable terminal is maintained as it is, and the structural coupling The stability of the

However, in recent years, there have been many cases of direct coupling type external devices. For example, Korean Patent Registration No. 1493332 (entitled: fingerprint input device using a portable terminal equipped with a camera and its external optical device for fingerprint input) is an external device of a type directly attached to a camera of a portable terminal It shows an example.

1 is a view schematically showing the shape of the enclosure 20 in concept. The enclosure 20 of FIG. 1 has the morphological features of the enclosure of this patent. In other words, when the enclosure 20 is mounted on the portable terminals 10a and 10b, the enclosure 20 is placed on the upper portion (or lower portion) of the portable terminals 10a and 10b, Is also held in contact with the front surface 13a and / or the back surface 13b of the portable terminals 10a and 10b. This combination of structures may be because the enclosure 20 has to functionally or structurally combine with other components (e.g., a camera) of the portable terminals 10a and 10b and the volume of the enclosure 20 itself There may also be an object to obtain the structural stability of the cursor coupling.

The problem is that the enclosure 20 of Fig. 1 is electrically coupled to the portable terminals 10a and 10b. Sockets 11a and 11b for electrical coupling of the portable terminals 10a and 10b are usually provided on a side face, a top face, or a bottom face that connects the front face 13a and the back face 13b. However, since the thicknesses of the portable terminals 10a and 10b are different for each manufacturer, the positions of the sockets 11a and 11b, particularly the distances from the front face 13a or the back face 13b, are different. 1, the widths of the portable terminals 10a and 10b are different from each other, and therefore, the positions of the sockets 11a and 11b are different.

Therefore, in a state where the plug 21 of the external device 20 is fixed in position, the position of the plug 21 is matched with the position of the socket 11a of the portable terminal 10a of (a) none. However, the position of the socket 11b of the portable terminal 10b of Fig. 3 (b) can not be inserted because it does not match the position of the plug 21. In some cases, since the external device 20 and the portable devices 10a and 10b are coupled with each other even when they are inserted and coupled, the external device 20 can not be stably supported in the portable device. In other words, in a state where the position of the plug 21 is fixed, the position of the socket can not correspond to other portable terminals for each manufacturer. Maybe this problem is blocking the development of various external devices.
