Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an electronic card connector, and more particularly to an electronic card connector that can provide an electronic card inserted above. [Prior Art] Electronic cards that can be used for memory devices can be classified into three types: miscellaneous memories, optical storage technology disks, and semiconductor technology rewritable memory. Among them, FlashMem〇ry products are the most popular and most popular among consumers and consumers. They are generally called memory cards, such as: XD card (eXtreme Digita) SD (Secure Kiss 1) card, MMC (MultiMedia Card) ) Card, MS (Memory Stick Card) card, etc. Because these products are far superior to the above two traditional storage media in terms of convenience, power saving, fine-selling, and data transmission scale. At present, (4) is widely used in mobile information appliances such as digital cameras, digital cameras, and PDAs. When using the card of the same age, it is often necessary to ride the electronic card to suspend the electrical connection between the memory card and the action information (4). However, the memory card of each specification has different white contacts 4, so * the same type of memory card needs to be inserted into the electronic card connector is different, so the conventional (four) daughter card connection [its ship provides a single - specification The electric card slot ' does not have the function of reducing the electronic card of the wealth-saving specification, so that the use of the electronic card connector is limited, and the electronic card of each specification must be individually designed correspondingly (4) the sub-card connection (4) In addition, Newt’s money has been raised and the number of people who have made it is greatly distressed. In addition, in order to respond to the market's consumer demand and promote the wide application of memory cards in more products, and to integrate various memory cards of different specifications, there are currently electronic card connectors that can support a variety of memory cards of different specifications. Please refer to the tenth figure, which is a conventional electronic card connector 1 which can provide various specifications, including: an insulative housing 10 and a first terminal 21 disposed in the insulative housing 10', and a second terminal 22 , the second terminal 23'. The first terminal 21, the second terminal 22, and the third terminal 23 are electrically contacted with electronic cards (not shown) of different specifications. In use, it is only necessary to insert the electronic card into the electronic card connection n, but because the extension direction of the first terminal 21 is opposite to the insertion direction of the electronic card, the electronic card will collide with the first terminal 21, and the front side interferes with each other. Therefore, the pole (4) causes the money to force some of the terminals to be excessively deformed by the improper pressure of the electronic card, thereby affecting the coplanarity of the terminals. And because the first terminal 21 can support the electric lift of the 沁 specification and the F liter of the MMC _ test, after the use of the field, the terminal collapses __, which causes the electronic card to fail, and also reduces the electronic card and The actual life of the electronic card is connected to H. SUMMARY OF THE INVENTION In actual use, it is apparent that inconvenience and deficiencies are designed to be reasonable and effective in improving the above-mentioned deficiencies. The present invention has been proposed by the inventors for the prior art. Therefore, one of the objects of the present invention is that it can provide an electronic card connection to cry, by adding - bending scales _ _ _ wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei wei The direction (4) front-end pre-electronic card front contact, thereby maintaining a good electrical connection between the electronic card and the connector. The technical means adopted by the present invention to solve the problem of the prior art provides an electronic card concentricity, the body is assembled in the insulating group, and a shielding shell is covered on the body. Wherein, the terminal has a plurality of sub-segments, and the terminal is divided into a main body portion, and the end portion of the main body portion is bent to form a folded-folded f-fold portion, and the bent portion is used to reinforce the strength of the extension arm by bending a extending arm extending forwardly, and a contact portion at the top of the extending arm, the contact portion having a moving surface, the sliding surface being adapted to the contact surface of the electronic card, so that the contact surface of the electronic card when the electronic card is inserted The torque generated by the daughter card and the contact portion that gradually spreads the surface of the terminal is equal to the torque generated by the extension arm and the ridge fold. The new lifting terminal touches the deformation and obtains the terminal coplanarity of the terminal, and the extending direction of the extending arm is consistent with the insertion direction of the electronic card, so that the front surface of the contact surface of the electronic card is prevented from colliding with each other. ~ By means of this bribe lake technology, it can ensure that the terminals of the electronic card connector can maintain the undeformed Wei after multiple insertions and removals. In this way, _Electronics: Connect with the good electrical record of the electronic card connector and the extension (4) daughter card and electronic card connection = life. In order to further understand the object, the structural features and the functions of the present invention, the following is a detailed description of the following: [Embodiment] 1280696 Referring to the first to fourth figures, the present invention provides an electronic card connector, The electronic card connector j is electrically connected to the electronic card 5, and the electronic card connector j includes an insulative housing 10, a terminal set 2〇 disposed in the insulative housing 1〇, and a shielding housing 30.

The width of the intermediate card slot 403 is the largest, the width of the upper card slot 402 is second, and the width of the lower card slot 404 is the smallest. Thus, the intermediate card slot and the lower card slot form a τ-type card slot. The combination of the card slots that are torn by the insertion port enables automatic recognition of the electronic card of the sd specification and the electronic card function of the XD specification and prevents mis-insertion. A plurality of engaging portions 1〇6 are protruded from the outer sides of the left and right arms 103 and 104 for holding the shielding case 30. In addition, the shield case 30 includes a substrate 302, and the side wings 304 are formed by bending downwardly from the corresponding sides of the substrate 3〇2. The substrate 3〇2 and the side flaps 304 are each formed with a plurality of elastic pressing sheets 301 which are formed by punching the shielding shell 3, and the elastic pressing sheets 301 are formed at the ends to form a free end 3010, and The lower elastic extension is used to elastically resist the top surface of the inserted electronic card 5 by the elastic pressing sheet 301, thereby achieving the purpose of clamping the electronic card 5 and maintaining good electrical conductivity between the electronic card 5 and the electronic card connection 1. connection. In order to ensure that the concealer housing 30 is firmly mounted on the insulative housing 1 , the side X 304 of the shielding body 3280696 is also provided with a plurality of deductions corresponding to the engaging portions ι 6 of the insulative housing 1〇. After the holes 3_ are engaged with the engaging holes 3_ and the engaging portions, the shielding shell 30 can be integrated with the insulating body 1 . The terminal set 20 includes three rows of terminals: a row of first terminals 2, a row of second terminals 22, and a row of third terminals 23. The first terminal 21 can support the electronic card of the sd specification and the electronic card of the MMC standard, and the second terminal 22 can support the electronic card of the xd specification. The ^23 can support the electronic card of the MS specification, thereby realizing The electronic card connector 1 of the present invention is compatible with four different types of electronic cards 5. The first terminal 21 includes a main body portion 21A, a bent portion 2n formed by folding one end f of the main body portion 21G, and a first welded portion 212 extending from the other end of the main body portion 210, and the bent portion 211 is forwarded An extended extension arm 213, and a first contact portion 214 located at the top of the extension arm. The bending portion 211 is used to reinforce the strength of the extension arm, and the length thereof is smaller than the length of the extension arm 213, and the bending portion 211 can maintain a better elastic state due to a certain angle of folding. The first contact portion 214 has a sliding surface 2HG which has a scale and is adapted to the contact surface (not shown) of the electronic card $. The second terminal 22 has a second tandem portion 22. And a thin second contact portion 221. The third terminal 23 has a third tandem portion 23A and a bridge-shaped third contact portion 232. #When the terminal group 20 is wired to the insulation (4), the divisional terminal-terminal 2 Budi-&sub-22, the third terminal 23 is placed to the corresponding first terminal slot drawing, the second terminal slot (10), the third terminal groove_.

The welding portions of the first, second and third terminals extend out of the insulating body 1 and are soldered to a circuit board (not shown) to achieve an electrical connection. When the field electronic card 5 is inserted, the contact surface of the electronic card 5 gradually slides along the sliding surface of the first terminal, and the first terminal 21 is subjected to the stress of the electronic card 5, resulting in the change of the force f, that is, the extending arm 213 and The force arm corresponding to the bent portion buckle, wherein the initial extension arm 213 has a longer length and is smaller, and when the electronic card $ is inserted, because the length of the bow portion 211 is small, a large stress is generated. Thereby, the deformation resistance function of the terminal is improved and the preferred terminal coplanarity is obtained, and the extending direction of the extension arm 213 is consistent with the insertion direction of the electronic card A. Therefore, the contact surface T of the terminal 21 and the electronic card $ is prevented from colliding. 'The phenomenon that the electronic card 5 and the terminal 21 are mutually stuck does not occur. Thereby, the electronic card 5 and the electronic card connector .1 have good electrical energy and extend the service life of the electronic card 5 and the electronic card connector 1. The terminal group 2 is further provided with a plurality of ground ends + 24, which are disposed in the recesses (not shown) of the insulating body two 103' 104.
