[0032] Please continue reading Figure 1 , Figure 6 , Figure 7, which are respectively a three-dimensional appearance diagram, a top view cross-sectional diagram of a card entry, and a top view cross-sectional diagram of a card exit of the utility model. It can be clearly seen from the figures that the sliding seat body 3 is pushed in for fixing, and the abutting wall surface 311 of the main body 31 of the sliding seat body 3 can be pushed in and abutted against the abutting surface 1212 of the abutting portion 1211 of the connecting rod 121, so that the connecting rod 121 is pushed into the receiving space 14, and the positioning portion 1214 bent and extended at one end of the connecting rod 121 will push the inner wall surface of the positioning groove 1220 of the push rod 122 outward by the thrust, so that the push rod 122 is pushed outward by the thrust of the positioning portion 1214, and the limit block 123 provided on the push rod 122 is limited by The limit groove 24 of the shell 2 will not move outward excessively. At the same time, as the sliding seat body 3 is pushed in, the protrusion 2111 protruding on the elastic arm 211 on both sides of the shell 2 will pass through the second recess 3123 and extend into the first recess 3121. The angled wall surfaces 3124 on both sides of the second recess 3123 are inclined, so that the protrusion 2111 can be displaced more easily without being positioned. The vertical wall surfaces 3122 on the first recess 3121 are clamped by the protrusions 2111 on both sides of the shell 2 and will not withdraw, thereby allowing the sliding seat body 3 to cooperate with the locking portions 21 on both sides to clamp and position the sliding seat body 3 while maintaining the balance of the two sides, thereby achieving the effect of correcting the position of the sliding seat body 3 from being offset.

[0033] If the sliding seat body 3 needs to be withdrawn, the pushing surface 1222 of the pushing portion 1221 of the push rod 122 can be pushed to make the push rod 122 slide inwardly along the sliding channel 16, so that the positioning portion 1214 of the connecting rod 121 in the positioning groove 1220 of the push rod 122 is pushed outward by the push rod 122, and the pushing surface 1213 of the push rod 122 will be further tilted outwardly at an angle and then push against the surface of the supporting wall 311 of the sliding seat body 3, and push the sliding seat body 3 outwardly by a certain distance, so that the protrusions 2111 originally arranged in the first recesses 3121 are displaced into the second recesses 3123 as the sliding seat body 3 is pushed outward (such as Figure 7 As shown), the card entry and exit actions of the card connector of the utility model are completed.

[0034] In addition, the sliding seat body 3 can further push the pushing groove 1223 on the pushing surface 1222 of the push rod 122 by passing the rod of a screwdriver through the through hole 3130 on the surface of the force-applying portion 313 , thereby achieving the effect of ejecting the card.

[0035] Furthermore, each of the elastic arms 211 is connected to the housing 2 via the folding arms 212 at both ends, thereby reducing the outward movement of the elastic arms 211, thereby reducing the amplitude of left and right movement of the sliding seat 3 when it is pushed into the accommodating space 10, thereby achieving the purpose of reducing elastic fatigue of the elastic arms 211 due to frequent movement.

[0036] In addition, the utility model is mainly aimed at providing at least one pushing device 12 in the insulating seat body 1, and covering the insulating seat body 1 with the shell 2 with the locking parts 21 on both sides, so that when the sliding seat body 3 is pushed in, it can cooperate with the locking parts 21 on both sides to be positioned and at the same time correct the left and right position of the sliding seat body 3 without being displaced. The main feature of the utility model is that each elastic arm 211 is connected to the shell 2 by the folding arms 212 on both sides to reduce the amplitude of the left and right movement of the sliding seat body 3 when it is pushed into the accommodating space 10, so as to achieve the purpose of reducing the elastic fatigue of the elastic arm 211 due to frequent movement, which is a secondary feature.

[0037] The above description is only a preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present utility model specification and drawings should be included in the patent scope of the present utility model and are hereby stated.
