Antenna spring and electronic device

An electronic device, comprising:

• a frame;
• an antenna spring;
• a circuit board;
• and
• an electrically conductive elastic piece,
• wherein the antenna spring, the circuit board, and the electrically conductive elastic piece are all mounted on an inner side of the frame, the frame comprises a frame antenna, and the antenna spring is located between the frame antenna and the circuit board;
• the antenna spring comprises a fastening portion, an abutting portion, and a connecting portion, wherein the fastening portion and the abutting portion are both fixedly connected to the connecting portion, the fastening portion is fixedly connected to the frame antenna, and a projection of the abutting portion on the connecting portion is spaced from the fastening portion;
• and
• the electrically conductive elastic piece is mounted on a side that is of the circuit board and that faces the antenna spring, and abuts against the abutting portion;
• wherein the fastening portion comprises two sub-fastening portions, the two sub-fastening portions are respectively and fixedly connected to two opposite sides of the connecting portion in a length direction of the antenna spring, the two sub-fastening portions are both spaced from the projection of the abutting portion on the connecting portion in a width direction of the antenna spring, and each of the sub-fastening portions is provided with at least one solder joint position.
