1. A card holder, comprising:
a connecting portion extending in a first lateral direction; and
two holding portions respectively arranged on two sides of the connecting portion in a length direction, the first lateral direction is the same as the length direction, a first end of one of the holding portions in a length direction of the holding portions is connected to one end of the connecting portion in the length direction of the connecting portion, and a first end of the other of the holding portions in the length direction of the holding portions is connected to the other end of the connecting portion in the length direction of the connecting portion, the two holding portions and the connecting portion enclose a card slot, the card slot being configured to mate with a card so as to limit the card in the card holder, and second ends of the two holding portions are spaced apart from each other and enclose an access opening, the access opening being in communication with the card slot and configured to allow the card to enter and exit the card slot;
the holding portions are arranged obliquely toward a center line of the card slot in a second lateral direction perpendicular to the first lateral direction such that a size of the access opening is smaller than a width of the card slot in the first lateral direction, the second lateral direction and the length direction of the connecting portion are perpendicular, and the holding portions are each a structure made of an elastic material to enable the holding portions to move in a direction away from the center line of the card slot in the second lateral direction during insertion of the card into the card slot through the access opening; and when the card mates with the card slot, the holding portions are still arranged obliquely toward the center line of the card slot in the second lateral direction, or the holding portions are arranged parallel to the center line of the card slot in the second lateral direction, so as to increase clamping forces applied by the holding portions on the card;
wherein a limiting protrusion and a first mounting guide slope are provided at each of the second ends of the holding portions, the limiting protrusion being located between the card slot and the access opening and configured to abut against the card so as to limit the card in the card slot, and the first mounting guide slope being arranged on the limiting protrusion, being located on a side close to the access opening, and being configured to slidably mate with a side portion of the card so as to guide the insertion of the card into the card slot;
wherein an included angle between the first mounting guide slope and the second lateral direction is A2, where 200≤A2≤50°;
wherein a second mounting guide slope is further provided at each of the second ends of the holding portions, the second mounting guide slope being arranged on the limiting protrusion, being located on a side close to the card slot, and being configured to slidably mate with the card so as to guide detachment of the card from the card slot;
wherein the limiting protrusion is further provided with a first arc portion, the first arc portion being arranged to protrude in a direction approaching the center line of the card slot in the second lateral direction, and the first arc portion being connected to the first mounting guide slope and the second mounting guide slope;
wherein the first arc portion has a radius of d, where 5 mm≤d≤7 mm.
