The upper row of terminals 40 has a vertical base. 41. The first holding portion 42, the first welding portion 43, and the first contact portion 44 are protruded from the base 41. The first holding portion 42 has a barb 42 that interferes with the inner wall surface of the terminal groove 36 to fix the upper row of terminals 4 to the main body 31. The first welded portion 43 side extends from the bottom edge of the base 41 to the front end surface 33 of the main body 3, and can be connected to the board to achieve miscellaneous connection. The first contact portion of the funnel base Μ the top edge is bent upward and forwardly formed to form a first elastic arm 44. The first elastic arm is fixed at the end end of the socket 32. The first contact is torn to realize electrical connection with the metal card body inserted into the electronic card. As shown in Figure 5, a number of lower row terminals are stamped and formed from a thin metal plate. The lower row of terminals 50 is self-insulating body rear end face 34 __ corresponding to the terminal groove 37 of the main body 31, and the sub-tank 37 is squashed. % is provided with a fixing block 38 of _ lower discharge %, the fixing block 38 is provided with a second fixing groove 38] and a third fixing groove is carried out 'the third fixing groove 3 is fixed groove 38, the first port 4 381 Lower and shorter than the second solid direction 1 slot 381 and the third fixing slot 382 between the rear end face 34 block 383; the lower row of terminals 50 have a base 5 protruding from the base of the second retaining portion 52, the third The holding portion of the holding portion 54. The second holding *(3) and the younger one are extended, and the second solid has an edge which is opposite to the wall of the second fixing groove 381 by the edge of the second fixing groove 381. The holding portion 55 is extended from the lower edge of the base body 5! to the third girth groove: a notch 56 is formed between the second portion 52 and the third holding portion 55. The base body 51 is extended by the upper and lower sides. The portion is fixedly balanced, and the middle portion is closely matched with the bump 383 by forming the notch 56, so that the lower row terminal 5 can be firmly fixed and fixed The edge body 30 corresponds to the corresponding terminal groove 37 to prevent looseness, floating needles, and the like. 'The lower row terminal 5', the second soldering portion S3 extends from the bottom end of the base body 51 toward the rear end surface 34 of the main body 31. The second contact portion 54 is obliquely bent upward and extends forward from the middle end of the base 51, and the second contact portion includes an oblique arm extending obliquely to the rear end surface 34. 54G, a second elastic arm 541 connected to the inclined arm (10) and a third elastic arm (4) connected to the second elastic f 541, and a middle portion of the second elastic arm 541 is provided with a segment curved portion 542, and the curved portion 542 is The elastic force of the second elastic arm 541 is enhanced, the third elastic arm 543 is bent upward from the end of the second elastic arm 541 and extends toward the rear end surface 34, and the second elastic f 541 and the third elastic arm M3 are formed with a bidirectional elastic arm. 'There is a good (four) recovery in the formation of the external force, so that the second contact 54 remains elastic after the force but is not easy to break. In the third elastic arm, the convex top is convexly protruded into the slot 32. a second contact 544. The oblique object extends obliquely toward the main body end surface 34 but does not exceed the rear end of the main body 31 34, the second touch 32 'and the first, _ respectively with the insertion slot 32 t electronic card upper and lower metal sheet contact, the electrical connection between the motherboard. "The financial needle, the edge connector and the focus of this creation are: The lower row terminal 5Q of the electrical connector 7G is extended from the lower edge of the base body 51 to have a third domain portion, and the surface of the second sagittal portion has a fixed=fine'. When the terminal is stressed, the base body can be fixed up and down to prevent the lower portion. Disadvantages such as loose terminals and floating needles.
