Description

[0001] CHARGING DEVICE FOR PORTABEL TERMINAL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging device for a portable information device, and more particularly to a charging device capable of charging a portable information device such as a smart phone or a tablet computer in both wireless charging and wired charging.

Recently, portable information devices such as a smart phone or a tablet computer have been used in addition to a wired charging method that is commonly used. Electromagnetic induction method is mainly used as a wireless charging method.

The wireless charging by the electromagnetic induction method is performed by a receiving body having a wireless charger equipped with a transmitting coil and a receiving coil generating an induced current by a magnetic field generated by the transmitting coil.

In recent years, portable information devices having a built-in receiving body that generates an induced current by such electromagnetic induction, an internal space capable of embedding a receiving body, and a terminal to which a receiving body is connected have been popular, but most smart phones and tablet computers Has a structure that does not contain or can not contain a receiving body.

In particular, in the case of a smartphone integrated with a battery without a back cover, a separate wireless charging receiver is used because a receiver for wireless charging can not be built in.

The wireless charging receiver is formed in the form of a thin patch and attached to the back of the smartphone and inserted into a slot for charging and data input / output of the smart phone, which is extended by a cable from the body of the wireless charging receiver, To the smartphone.

When using the wireless charging receiver with this configuration, the charging terminal is inserted in the slot of the smartphone. Therefore, if the smartphone is charged in an environment without the wireless charger, the charging terminal is disconnected from the slot of the smartphone, It is inconvenient to insert the charging terminal of the smartphone into the slot of the smart phone.

Particularly, when the charging terminal of the wireless charging receiver and the charging terminal of the wired charger are repeatedly inserted and replaced, the charging terminals of the charging devices as well as the terminals in the slots of the smartphone are frequently worn or damaged.

In order to solve such a problem, Korean Patent No. 10-1575956 (Document 1) proposes a charging device having a configuration in which a charging terminal of a wire charging device can be connected to a charging terminal of a wireless charging receiver.

Fig. 1 shows a charging device of Document 1. 1, there is provided a wireless charging case 200 having a receiving coil 210 for generating an induced current by electromagnetic induction and a charging circuit 220.

A smart phone (not shown) is inserted into the wireless charging case 200, and an inserting terminal 310 inserted into the charging port of the smart phone is inserted into the case to supply the induced current from the charging circuit 220 to the smart phone. Respectively.

A connection terminal 320 is formed on the outside of the wireless charging case 200 in a concave shape. A gender 400 for wire charging is coupled to the connection terminal 320. One side of the gender is connected to the connection terminal 320 of the wireless charging case by a magnetic force to provide a connection terminal. On the opposite side of the connection terminal, a charging port 430 for inserting a cable 500 for supplying power from external power Is formed.

According to the configuration of the wireless charging case of Document 1, the smart phone is always inserted in the wireless charging case 200, and when the wireless charging is performed, the wireless charging case 200 is placed on the wireless charging pad, The gender 400 is connected to the connection terminal 320 and the cable 500 is connected to the gender 400 so that wire charging is performed.

However, in the charger of the document 1, it is inconvenient to always insert a portable information device such as a smart phone into the charging case. In addition, in order to charge the cable with the cable for charging the wired device, a separate gender is provided, There is a problem that the wireless charging case must be connected again.

Furthermore, in the charger of Document 1, the gender is coupled to the connection terminal of the wireless charging case using magnetic force. The coupling between the connection terminals by such a magnetic force causes not only a strong force such as an external impact but also a self- It is not stable as a physical connection means for electrical connection.
