Sim card is manufactured and used in various sizes such as mini SIM card, micro SIM card and nano SIM card. These cards have different sizes, so the sockets must all be the same size. Thus, if a different socket for each card is a factor that increases the unit price of the product, the card adapter (3) has been developed and used to use both a large SIM card and a small SIM card in the same socket. In other words, in the case of a large SIM card, the card adapter is used without being used, and in the case of a small SIM card, the SIM card is used in combination with the card adapter.

When the mobile terminal is shipped from the factory, the card adapter is generally coupled with the card socket. In addition, in some cases, only the card adapter is coupled to the card socket without coupling the SIM card to the card adapter.

As shown in Fig. 5, the card adapter 3 has a card coupling hole 3a for inserting and inserting the SIM card. When inserting the card adapter 3 into the card socket, the connection terminal is inclined in the insertion direction. Since it is formed, the card adapter 3 can be inserted smoothly without being disturbed by the connection terminal. However, when the card adapter 3 is detached from the card socket, the card coupling hole 3a of the card adapter 3 is caught by the end of the connection terminal and is not easily separated, and the connection terminal is deformed due to excessive force. It can be damaged. This problem can be solved by providing the auxiliary terminal 220 in the present invention.

The tip is located below the inner bottom surface of the housing 100.

When the card adapter 3 is coupled to the card socket 1, the edge of the card coupling hole 3a is not in contact with the tip of the connection terminal 200. Even in the contacted state, the main terminal 210 is not in contact with the upper surface of the distal end of the auxiliary terminal 220.

As shown in FIG. 7, when the card adapter 3 is pulled to separate the card adapter 3, the edge of the card coupling hole 3a preferentially contacts the upper surface of the front end of the auxiliary terminal 220, thereby pressing the auxiliary terminal 220 downward. . As such, when the auxiliary terminal 220 is pressed down, the main terminal 210 which is integrally connected to the auxiliary terminal 220 is lowered, and the tip thereof is lowered down to the inner bottom surface of the housing 100. Therefore, the edge of the card coupling hole 3a does not catch on the tip of the main terminal 210.

As shown in FIG. 8, when the card adapter 3 is continuously pulled out, the peripheral portion of the card coupling hole 3a is smoothly separated from the card socket 1 while pressing both the auxiliary terminal 220 and the main terminal 210. Can be.
