By adopting the technical scheme, because the IC card may have an electrostatic effect, when the IC card contacts the reading terminal, false signals can be possibly caused to interfere, and the vertical length of the first anti-interference piece is larger than that of the insulating base, so that the first anti-interference piece protrudes out of the insulating base, and the IC card contacts the first anti-interference piece when extending into the IC card, so that static electricity on the surface of the IC card is transferred away through grounding. Thereby forming a good effect of reading the IC card chip. In addition, the first anti-interference piece is positioned at one side of the card inserting port, so that static electricity can be eliminated preferentially after the IC card is inserted, and then the card reading is performed, and the reading effect of the IC card holder connector is improved.
Optionally, the reading terminal assembly includes a first reading terminal and a second reading terminal, the first reading terminal and the second reading terminal are arranged in parallel, and a distance between the first reading part and the bayonet is smaller than a distance between the second reading part and the bayonet; the distance between one side of the first reading terminal far away from the bayonet and one side of the second reading terminal far away from the bayonet is equal to that between the first reading terminal and the second reading terminal; the area between the other side of the first reading terminal and the other side of the second reading terminal is a reading area.
By adopting the technical scheme, when the IC card is stretched into the reading area, the content on the chip can be read when the chip in the IC card is positioned in the reading area; when the direction of the IC card is extended or the position of the damaged chip of the IC card is deviated, the IC card holder connector cannot read, so that the IC card holder connector cannot reflect the error reading result, and the identification reading effect of the IC card holder connector is maintained.
Optionally, the first reading terminal includes a first embedded portion, a first reading portion and a second reading portion, one end of the first embedded portion is fixedly disposed on a groove wall of the reading groove, the other end of the first embedded portion is connected to one end of the first reading portion, the other end of the first reading portion is fixedly connected to one end of the second reading portion, and the other end of the second reading portion is fixedly disposed on the groove wall of the reading groove; the first reading part has an included angle with the horizontal direction, and one end of the second reading part, which is close to the first reading part, also has an included angle with the horizontal direction; and a recess is arranged on one side of the first reading part far away from the second reading part, and the recess is positioned in the reading groove.
By adopting the technical scheme, when the IC card enters the reading area, the chip position of the IC card needs to be pressed against the first reading part and the second reading part, so that a stable reading effect is formed. Because the first reading part and the second reading part have horizontal included angles, after the chip of the IC card is pressed against the first reading part and the second reading part, the first reading part and the second reading part are bent, so that the surface of the IC card is prevented from being scratched. The concave arrangement makes the bending effect of the first reading part better, because the first reading part and the second reading part form a bulge, and the first reading part is connected with the first embedded part, when the concave is not present, the IC card is pressed against the first reading part, the stress pivot of the reading terminal is positioned at the first embedded part, the stress length is long, the bending amplitude is small, and the surface of the IC card is possibly damaged.
