(2) The plug 2 has a base 21 and a plurality of protrusions 22 protruding upward from the base 21, the first base 21 and the first surface 121 are located on opposite sides of the key portion 13 in the longitudinal direction X, the protrusions 22 protrude into the second receiving groove 142 receiving the signal terminal 4a instead of the second receiving groove 142 receiving the ground terminal 4b, and the protrusions 22 protrude upward beyond the second surface 122. The convex portion 22 is configured to change the dielectric constant around the signal terminal 4a more than the dielectric constant around the ground terminal 4b, so that the impedance of the signal terminal 4a can be adjusted to satisfy the matching impedance required for the signal terminal 4a to transmit a high-frequency signal.
(3) The height difference H1 between the first surface 121 and the second surface 122 is smaller than or equal to the height difference H2 between the first mating portion 6 and the second mating portion 7, so that the longer second surface 122 serves as a positioning surface against which the second mating portion 7 abuts, and the electronic card 200 is more stable after being inserted into the slot 12 and is less prone to tilting to one side in the longitudinal direction X.
(4) In the up-down direction Z, the distance S3 between the first contact portion 31 and the first surface 121 is greater than the height difference H1 between the first surface 121 and the second surface 122, so that the slot 12 portion having the first surface 121 has a sufficient depth for the first contact portion 6 to be inserted downward, and the first conductive sheet 61 is prevented from being in a high position due to insufficient downward movement distance, and thus being unable to contact the corresponding first contact portion 31 to form an electrical connection.
(5) The taper formed by the two first conductive slopes 62 is greater than the taper formed by the two second conductive slopes 72, so that a sufficient distance still exists between the lower end of the first conductive sheet 61 and the upper end of the first conductive slope 62 in the vertical direction Z, thereby preventing the lower end of the first conductive sheet 61 from being easily damaged due to being too close to the upper end of the first conductive slope 62.
