detailed description:

First, please refer to FIG. 1 , FIG. 2 and FIG. 3 at the same time: wherein the card reader 1 of the present invention comprises at least one housing 11 , a base 12 and a card ejecting structure 14 and four connecting terminals 13 ; The housing 11 is made of metal The utility model is formed into a π-shaped shape, wherein the two symmetric folding portions (110, 110') are provided with a fastening hole 112 corresponding to the buckle portion 121 of the base 12 to serve as a fastening member for the base 12 to be coupled with the housing 11. Further, a downwardly pressing pressing piece 111 is formed on the top of the casing 11, and the pressing piece 111 also corresponds to the concave portion 1426 of the sliding block 142 as a restriction against the displacement of the sliding block 142 in the base 12.

The base 12 is mainly for the connection of the connection terminal 13 for the memory card to be inserted, wherein the two corresponding convex portions (123, 123') serve as guide rails for guiding the memory card, and the connection terminals 13 are embedded in the middle. The sliding portion 126 is provided with a sliding slot 126. The sliding slot 126 is defined by the slider 142 of the card retracting structure 14 and a U-shaped slot 122 is disposed at the front end of the sliding slot 126. The π-shaped rod 143 is disposed at the end of the retracting structure 14 , and a positioning bolt 125 is disposed at the other end of the sliding slot 126 . The positioning pin 125 is fixed to the spring 141 of the ejecting structure 14 .

The ejector structure 14 includes a spring 141, a slider 142 and a π-shaped rod 143. The slider 142 has an L shape, and one end is provided with a buckle 1421, and the other end is provided with a resisting portion 1424, and the π-shaped rod 143 is spanned. The concave portion 1426 of the slider 142 is provided with an arc portion 1425 at the end of the slider 142 as a forward pushing and retracting action of the control slider 142; and a positioning pin 1422 is provided in front of the recess portion 1426 for the spring 141. The spring 141 mainly provides a reaction force for the displacement of the slider 142 to return.

Further, the connecting terminal 13 bulges a curved contact portion 131 at the end portion, and has an elastic force for lifting. When the memory card 2 is inserted, the connecting terminal 13 is coupled to the memory card 2 by the reaction force of its own compression. The connection point is contacted, and the read connection is completed; however, the fixing of the entire card reader 1 is performed by the connection of the terminal 13 at the front splicing portion 132 to the fixed circuit board.

Please also refer to Figure 4 to Figure 6, when the memory card 2 is inserted, when While the front end of the memory card 2 abuts against the blocking portion 1424 of the slider 142, the buckle groove 22 of the memory card 2 falls into the buckle 142 1 of the slider 142 to form a state of a buckle, and then the memory card 2 is pushed forward. At the end, the spring 141 is squeezed, and the π-shaped rod 143 is in a resisting state. After being released, the π-shaped rod 143 completely resists the slider 142, and the slider 142 is restricted to make the memory card 2 In the buckled state, the front corner 2 1 of the memory card 2 corresponds to the resisting portion 1424 of the slider 1 42 to prevent the memory card 2 from being misplaced; and when the memory card 2 needs to be withdrawn, only the memory card 2 needs to be Pushing, the π-shaped rod 143 is disengaged from the slider 142, and when the spring 14 1 is released to push the slider 142 to be retracted, the memory card 2 can be restored to the originally placed position for pulling out.

In summary, the card reader of the utility model adopts an easy-to-operate push-pull/pop-up (pu s h-pu sh) method, has a pop-up stroke, and also designs a locking mechanism to prevent the memory card from being pre-warmed. The points are completely in accordance with the requirements of the patent application; the above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the implementation of the present invention. That is, the equal changes and modifications made by the patent application scope of the present invention are covered by the scope of the utility model patent.
