Patent ID: 8727798

Claim:
A coaxial connector, for being soldered to a circuit board and capable of receiving an external device to be inserted therein, comprising: a receiving cavity, having an inserting interface for receiving the external device to be inserted therein; a first terminal, mounted and fixed within the receiving cavity, and having a first soldering portion and at least one first contact portion, wherein the first soldering portion is used for being soldered to the circuit board; and a second terminal, mounted and fixed within the receiving cavity, and having a second soldering portion and at least one second contact portion, wherein the second soldering portion is used for being soldered to the circuit board, wherein, before the external device is inserted into the coaxial connector for the first time, the first contact portion and the second contact portion form a first relative positional relationship; when the external device is inserted into the coaxial connector, the external device presses against and contacts the second contact portion downwards, so that the second contact portion is detached from the first contact portion, and the first contact portion and the second contact portion form a second relative positional relationship; and after the external device is disengaged from the coaxial connector, the second contact portion urges against the first contact portion upwards to form a third relative positional relationship, wherein the third relative positional relationship is different from the first relative positional relationship.
