The ground pad 102 is electrically connected to a metal shielding layer 103, and the metal shielding layer 103 is preferably a thin metal plating layer, such as a gold plating layer; the signal pads 101 and the ground pads 102 are arranged in a single row in at least one direction of the connector 100, and the connector 100 in the present disclosure may have a closed cavity structure with a variable geometry as required, preferably a polygonal solid structure, such as a quadrangular solid frame type structure or a pentagonal solid frame, or a hexagonal solid frame, where one frame of the connector 100 represents one direction; the signal pads 101 are disposed between the ground pads 102, and on at least one frame of the connector 100, the signal pads 101 are sandwiched by the ground pads 102, for example, at least 1 signal pad 101 is disposed between every two ground pads 102, and in order to arrange the signal pads 101 as much as possible, it is preferable to dispose 2-4 signal pads between every two ground pads 102. In addition, at least 3 ground pads 102 are provided on each frame of the connector 100.

The signal pads 101 on the frame of the connector 100 in the present disclosure, that is, the signal pads 101 in each direction, may transmit different signals as needed, for example, the signal pads 101 for transmitting high-speed signals are disposed in at least one direction of the connector 100, a row of ground pads 102 is disposed inside the signal pads 101 in the direction, for example, a ground pad row 1020 composed of the ground pads 102 as illustrated in fig. 2 is disposed, and based on the row of ground pads 1020 and the metal shielding layer 103 outside the row of ground pads 1020, it is possible to avoid interference caused to the high-speed signals transmitted by the high-speed signals, or to prevent the high-speed signals from interfering with components inside the connector 100 or surrounding the connector 100.
