Secondly, as shown in fig. 10a-10b, this situation is also applicable to the case where the first surface 1101 and the second surface 2101 are both tapered surfaces, in this case, one of the first conductive part 130 and the second conductive part 140 disposed on the first surface 1101 is a conductive ring, the other is a conductive contact, the conductive contact corresponding to the conductive ring on the first surface 1101 of the third conductive part 220 and the conductive contact corresponding to the conductive contact is a conductive contact of the fourth conductive part 230 disposed on the second surface 2101, and the distance between the conductive ring and the conductive contact of the first surface 1101 in the inserting direction is equal to the distance between the conductive ring and the conductive contact of the second surface 2101 in the inserting direction. It is understood that, for the case where the first surface 1101 and the second surface 2101 are both tapered surfaces, the radius of the tapered surface formed by the first surface 1101 and the tapered surface formed by the second surface 2101 in the plugging direction gradually decreases.
