When the electronic card is inserted into the receiving cavity 10, the contact portion 211 of the pressing conductive terminal 21 sinks, and the spring portion 212 is forced to sink, and the extending portion 213 and the connecting portion 214 are lifted upward. The extending portion 213 and the spring portion 212 are extended. The contact portion and the connection portion 214 are likely to gather a large stress. Since the spring portion 212 and the extension portion 213 are orthogonal to each other, the connection portion 214 is connected to the frame portion 210 to form a relatively stable "mountain" structure. Therefore, the stress is dispersed, and the breakage of the conductive terminal 21 can be effectively prevented.

In summary, this creation has indeed met the requirements of the new patent, and filed a patent application in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereby. Equivalent modifications or variations made by those of ordinary skill in the art in the spirit of the present invention are still covered by the appended claims.
