New Description: [New Technology Field] This creation is about an electronic card connector, especially an electronic card connector that increases the life of the SIM card connector. [Prior Art] The electronic card connector must have good electrical connection performance to ensure the normal operation of the electronic device and avoid an open circuit due to poor electrical connection. At present, most electronic card connectors maintain the electrical performance and accuracy, and the conductive terminal contacts are kept at the same height. Therefore, the conductive terminals need to have a preloading effect. The Chinese Patent No. 201018072 discloses an electronic card connector terminal including a base portion, a contact portion formed by bending from the base portion, and a pre-pressing portion formed by bending and extending from the end of the contact portion toward the base portion of the conductive terminal. The pressing portion extends to both sides to form a pressing hook portion, and since it is bent and extended toward one side of the base portion, it collides with the base portion when being pressed and pressed with the electronic card, and may lead to conduction in multiple pressing operations. The terminal contact portion is thus deformed and distorted, directly affecting the electrical connection performance of the electronic card connector, and increasing the instability of the product. In order to avoid the above problems, this creation proposes a new electronic card connector to make up for its shortcomings. [New content] φ The purpose of this creation is to provide an electronic card connector that can effectively protect the conductive terminals and increase the service life of the conductive terminals. . In order to achieve the above object, the present invention provides an electronic card connector including an insulative housing, a conductive terminal received therein, and a shielding housing covering the insulative housing, the conductive terminal including a base portion and extending from the base portion a welded portion and a contact portion, wherein a head portion extends from the contact portion toward the welded portion, and both side portions of the head portion are formed with a preloading arm extending toward the base portion. Compared with the prior art, the electronic card connector of the present invention has the following effects: the pre-pressure arm of the conductive terminal is disposed on both sides of the welding portion and the inclined portion, so that the pre-pressure arm does not collide when the electronic card presses the conductive terminal. The welded portion or the inclined portion protects the contact portion of the conductive terminal from deformation, thereby improving the service life of the product. 5 M363706 [Comprehensive application method] Please refer to the first ®• to the fourth figure. 'This creative electronic card connector 1 includes the absolute-10 and the conductive terminal 2收 in the insulated body. 30 is covered on the insulative housing 10. As shown in the second and third circles, the insulative housing 10 includes a main body portion 11 and side portions 12 on both sides thereof. The main body portion 11 is provided with a plurality of terminal receiving slots, and receiving slots. A partition wall 13 is disposed between the bottom of the partition wall 13 and a terminal fixing groove (4). The front end of the partition wall 13 extends toward the receiving groove 14 to form a thin plate-shaped pre-pressing plate 142. 3〇 includes a main body portion η and a covering portion 32 which is formed by bending downwardly from both sides of the main body portion 31. As shown in the second to third figures, the conductive terminal 20 includes a base portion 21 from one end of the base portion 21 The welded portion 22 formed by the extension forms a - inclined portion 26 between the base portion 21 of the disk welding rim 22. After extending from the other end of the base portion 21, the contact portion 24 is bent and extended to form a contact portion 24, and the bent portion 23 is bent between the base portion 21 and the contact portion 24. The contact portion 24 is convexly raised upwardly along the contact portion. 24 continues to extend obliquely toward the welded portion 22 to form a head portion 25'. The head portion 25 extends toward both sides, and a rear portion extends toward the bent portion 23 to form a pre-stressing arm 251. The preferred embodiment of the preloading arm 251 is straight to the head 25, i.e., parallel to the contact portion 24 and the base portion 21. In the manufacturing process, the conductive terminal 20 is manufactured by stamping, the pre-pressing arm of the head 25 is guided, and the terminal 20 is - integral 'in the stamping, but is formed directly by using the edge material which should be cut off. On the end of the head 25. The two pre-(four) 251 (10) lateral distances are greater than the width of the welded portion 22 and the inclined portion 26, and the height between the pre-stressing arm 25] and the welded portion 22 is smaller than the straight height between the head portion 25 and the welded portion 22 when the contact is 24 When the electronic card (not shown) is pressed downward to move downward, the pre-pressing arm 251 of the head portion 25 will move downward toward the space on both sides of the welded portion 22 and the inclined portion 26 without touching the glazing portion. 22 or the inclined portion 26 prevents the conductive terminal 2 () from being bent and deformed due to leakage, thereby prolonging the service life of the conductive terminal 2'. Referring to the first to fourth figures, in the installation process, first, the conductive terminal 2〇 is installed into the receiving groove 14 of the insulative housing 10, and the base portion 21 of the conductive terminal 2 is fixed in the receiving slot 14. In the groove 141, the soldering portion 22 and the contact portion % are respectively exposed downwardly and 6 M363706 - upwardly to the outside of the insulative housing 10. The pre-pressing arm 251 of the head portion 25 is located under the pre-pressing plate 142 formed at the front end of the receiving groove 14, and is in contact with it. The pre-pressing effect is achieved, so that the plurality of conductive terminals 20 are at a parallel height to improve the accuracy of the connection. Next, the shield case 30 is covered on the insulative housing 10, and the covering portion 32 covers the both side portions 12 of the insulative housing 10. At this point, the installation of the electronic card connector 1 is completed. Compared with the prior art electronic card connector, the electronic card connector 1 of the present invention has the pre-stressing arm 251 of the conductive terminal 20 disposed on both sides of the soldering portion 22 and the inclined portion 26, so that the head portion 25 of the conductive terminal 20 does not need to be bent inward. Folding, the distance between the head portion 25 and the welded portion 22 is appropriately increased, and the pre-pressing arm 251 is located in the space on both sides of the welded portion 22, which changes the contact between the head of the previous conductive terminal and the welded portion to deform the contact portion. Case. φ In summary, the creation complies with the new patent requirements and submits a patent application in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those who are familiar with the skill of the present invention are equivalent to the equivalent modifications or changes made by the spirit of the present creation.
