The wireless communication unit 23 With functional surface 231. The housing 1 is provided with a receiving cavity 12, and the sliding groove 11 communicates the receiving cavity 12 with the outside. After the wireless communication module 2 is assembled in the receiving cavity 12, the flexible circuit board 21, the magnet 22 and the wireless communication unit 23 are accommodated In the receiving cavity 12, the functional surface 231 of the wireless communication unit 23 penetrates from the sliding groove 11 to be exposed on the mating surface 10.

The wireless communication unit 23 is electrically connected to the flexible circuit board 21, and is used to convert the electrical signal of the flexible circuit board 21 into an electromagnetic signal and transmit or receive an external electromagnetic signal The electromagnetic signal is converted into an electric signal and transmitted to the flexible circuit board 21, and the functional surface 231 realizes the transmission or reception of the electromagnetic signal.

When the connector 100 is connected to the mating element, the magnet 22 and the mating element are magnetically attracted, so that the connector 100 is close to the mating element, and at the same time, the connector 100 is connected to the functional surface 231 of the wireless communication unit 23. The docking functional surfaces on the docking element are arranged close to and face to face, thereby realizing wireless transmission of signals between the connector 100 and the docking element. When the functional surface 231 and the docking functional surface on the docking element do not face-to-face and accurately align, the magnetic attraction between the magnet 22 and the docking element will drive the magnet 22 to move to drive the flexible circuit board 21 Move or be flexibly deformed, thereby driving the wireless communication unit 23 to move along the sliding groove 11, thereby adjusting the position of the functional surface 231, so that the functional surface 231 is accurately aligned with the docking element, thereby realizing the connector 100 The wireless transmission of the signal with the docking component, and to ensure the high-quality transmission of the signal.

Please refer to Figures 1 to 4, the connector 100 has a sliding direction for the wireless communication unit 23 to move along the sliding groove 11, a mating direction perpendicular to the functional surface 231, and a mating direction perpendicular to the sliding The direction and the lateral direction of the docking direction, the magnet 22 and the wireless communication unit 23 are located on the same side of the flexible circuit board 21, and are arranged side by side along the lateral direction at the same end of the flexible circuit board. The sliding groove 11 extends along the sliding direction, and the wireless communication unit 23 can move along the sliding groove 11 in the sliding direction, so that the functional surface 231 can be between a first position and a second position. Sliding between. The connector 100 has blocking portions 13 respectively blocking the two ends of the sliding groove 11 in the sliding direction to prevent the wireless communication unit 23 from escaping. The blocking portion 13 is formed on the housing 1 and blocks the wireless communication unit 23 when the functional surface 231 is located at the first position and the second position, respectively. The wireless communication unit 23 is provided with an abutting portion 232 that abuts against the housing 1 to prevent the wireless communication unit 23 from being separated from the sliding groove 11 along the docking direction. The magnet 22 is at least one of a permanent magnet, an electromagnet, and a ferromagnetic element.

The above-mentioned setting of the wireless communication module 2 as the above-mentioned connector 100 is only one of the use modes of the wireless communication module 2. Of course, the wireless communication module 2 may not be arranged in the housing 1, but directly arranged in the electronic device. In the case, when the wireless communication module 2 is docked with the docking element, and the functional surface 231 is not accurately aligned with the docking element, the magnetic field between the magnet 22 and the docking element The suction will cause the wireless communication unit 23 to move relative to the electronic device under the drive of the flexible circuit board 21, thereby adjusting the position of the functional surface 231.
