Description of the Invention: [Technical Field] The present invention relates to an electronic card connector, and more particularly to an electronic card connector in which an electrically conductive terminal is embedded. [0002] [0002] The prior art related to the present invention can be found in U.S. Patent No. 7, 43 5, 1 1 5 B2, issued on Oct. 14, 2008, which discloses an electronic card connector. The utility model comprises an insulating body and a plurality of conductive terminals fixed on the insulating body. The insulative housing is provided with a mounting wall, and the conductive terminal includes a mounting portion that is fixedly mounted in the mounting wall in an insert molding manner. However, after the insert molding, the upper surface of the mounting wall is higher than the upper surface of the mounting portion of the conductive terminal. By arranging, when the electronic card is inserted, the bottom surface of the electronic card must be inserted along the upper surface of the mounting wall, which inevitably increases the height of the electronic card connector. In other words, the prior art fixes the conductive terminals by providing a thicker mounting wall. [0003] However, as electronic products (such as mobile phones, tablets, etc.) are getting thinner and thinner, the corresponding electronic card connectors must also be thinner and thinner to meet customer needs. The problem is electronic There is not enough space inside the product for the thicker electronic card connector to be installed. [0004] Of course, reducing the thickness of the insulating body mounting wall is a feasible solution for reducing the overall height of the electronic card connector. However, once the thickness of the insulative body is thinned, the portion for fixing the conductive terminals is correspondingly reduced. How to stably hold the conductive terminals in this case has become a technical problem commonly encountered in the industry.

In the illustrated embodiment of the present invention, the width of the second mounting portion 22 is smaller than the width of the first mounting portion 21, thereby forming a stepped surface, which is more advantageous for fixing the conductive terminal 2. In addition, the first opening 212 and the second opening 222 are both rectangular, the same width and aligned in the electronic card insertion direction B-B, thereby reducing the difficulty of the pressing. The length of the first clamping portion 223 is greater than the length of the first positioning portion 213 and the third positioning portion 214. The second positioning portion 223 is adjacent to the welding portion 24 and is connected to the welding portion 24. Therefore, by fixing the second positioning portion 223, the number of the first positioning portion 223 can be 100115631. Form No. A0101 Page 9 / Total 25 pages 1002026193-0 201246704 The phase of the portion 24, that is, the welded portion Μ is not interesting because the fixing of the first and third positioning portions 213 and 214 is relatively stable. Referring to Fig. 8, the second positioning portion 223 is different in height from the first and third positioning portions 213, 214, so that a misalignment can be formed in the vertical direction to facilitate fixing of the conductive terminal 2. In the illustrated embodiment, the first positioning portion 223 is higher than the first and third positioning portions 213, 214, so that the second positioning portion 223 can deeply penetrate the center of the wall to ensure the insulating body 1 The strength of the foot dog holds the conductive terminal 2. [0024] [0024] The contact arm 23 is higher than the inner wall surface 14 of the mounting wall 11 and correspondingly above the hollow slot 17 for electrical contact with the electronic card. After the electronic card is inserted into the accommodating space 10, the contact arm 23 is deformed downward due to the pressing force of the electronic card, and the hollow groove 17 can provide sufficient deformation space to the contact arm 23, thereby reducing the electronic card connection. 〗 〖The role of the overall height. The welded portion 24 extends forward beyond the front end face 11 of the mounting wall u, and the welded portion 24 is lower than the second positioning portion 223 (refer to FIG. 8). By fixing the second positioning portion 223 in the mounting wall 11, it is ensured that the soldering portion 24 of the conductive terminal 2 has a better coplanarity for surface soldering (SMT). The conductive terminal 2 is received in the corresponding terminal mounting slot. The first positioning portion 213 is received in the first fixing groove 1612 and is pressed by the first fixing block 161. The second positioning portion 223 is received in the second fixing groove 1 622 and is fixed by the second fixing block. The third positioning portion 214 is received in the third fixing groove 1 632 and is pressed by the third fixing block 163. Since the first and third positioning portions 213, 214 are lower than the second positioning portion 223, the first and third fixing blocks 161, 163 may have a greater thickness to press the first, 100115631 form number A0101 10 pages / a total of 25 pages 1002026193-0 201246704 Three definite venge 213, 214, thereby improving the fixed effect. The second positioning portion 223 partially extends beyond the front end face 110' of the mounting wall 11 and the free end 224 of the second fixed portion 223 is pressed by the second fixing block 162. The upper surface 210 of the first ampoule portion 21 and the upper surface 220 of the second mounting portion 22 are both coplanar with the inner wall surface 14 of the mounting wall 11, that is, only the lower surface of the conductive terminal 2 is completely located on the mounting wall 11 Inside, thereby reducing the height of the electronic card connector 1 〇〇. [0025] Of course, the conductive terminal 2 may also be fixed to the insulative housing 1 in an insert-molding manner to save assembly costs, and the object of the present invention may also be achieved. The card ejecting mechanism 3 includes a slider 31, a spring 32 for providing an elastic force to the slider 31, and a link 33 for controlling the slider 31. The slider 31 is provided with a pressing force protruding into the receiving space 10. In the portion 311, the pressing portion 311 is driven by the electronic card to drive the slider 31 to move. The card ejecting mechanism 3 is a commonly used push-pUsh card ejecting mechanism in the industry, and its detailed working principle has been well known to those of ordinary skill in the art of electronic card connector technology, and will not be described herein. The creation meets the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those skilled in the art should be equivalent to the equivalent modifications or changes made by God of the present invention. It is covered by the following patent application.
