533626 V. Description of the invention (2) The orifice (not shown) is connected with the first lead pin 431, the second lead pin 432, and the ground pin 433 to the connection bar 421 42 2 and 42 by riveting. 3. 〇The bottom of the body 402 is formed with two support rods 44. The support rod 44 and the body 40 are integrally formed by the injection method. After the support rod 44 extends downward from the bottom portion 402 of the body by a specific length, it is expanded to both sides and then Reduced to form a protruding structure 443. The maximum transverse length of the protruding structure 4 43 is slightly larger than the widths of the insertion holes 33 and 34 of the circuit board 3. Since the supporting rod 4 3 itself has a unique spring of plastic material = ’, applying an external force can cause the protruding structure 433 of the supporting rod 43 to pass through the jacks 3, 34 ′ to assist the AC connector 4 to be positioned on the circuit board 3. The first lead pin 431 and the second lead pin 432 extend downward so as to be inserted into the foot holes 31 and 32 of the circuit board 3 (see the first figure (a)).

About the structure of the support rod 5 4 and the ground pin 5 3 3

533626 V. Description of the invention (5) and principle are familiar to those skilled in the art, so I won't go into details here. The feature of this case is that the structure of the first lead pin 531 and the second lead pin 532 is different from the conventional technique, for example, it is bent upward by a length, and a wire 55 and a circuit board (not shown, The working principle and configuration of the circuit board in this case are also known, and will not be repeated here) to form an electrical connection; furthermore, a step above the body 50 corresponding to the welding point is provided with a protruding plate [os] to reduce the exposure of the welding point . The fourth figures (a) to (c) show the winding conditions of the lead pins applied to the AC connector structure of the case. Taking the first lead pin 531 as an example, in the fourth figure (a), the 'first lead pin 531 mainly has an opening 5311, a perforation 5312, and a winding area 5 3 1 3. The opening 5 3 1 1 is used to connect with an opening (not shown) corresponding to the back side 501 of the body, so as to rivet the first lead terminal 5 1 1; the winding area 5313 is substantially T-shaped. Next, the bare wire end 551 of the electric wire 55 is passed through the perforation 53 12 (preferably, a part of the insulation sleeve 5 5 2 is also passed through the perforation 5312 to provide better flexibility) and further wound around the winding area 5 3 丨 3 (in the fourth Figure (b)) "Finally, the solder 554 is applied at the spot welding step of the bare wire end 551.
