[0010] Referring to the second, third, fifth, sixth and seventh figures The shielding housing 2 is formed by stamping and bending a metal sheet, and includes an upper wall 21, a lower wall 25, and a first side wall 27 and a second side wall 26 on both sides of the lower wall 25. The height of the first side wall 27 is greater than the height of the second side wall 26 and directly connects the upper wall 21 and the lower wall 25, and the second side wall 26 extends vertically from the lower wall form number A0101, page 6 / total 20 pages 25 The slanted section 22 is connected to the upper wall 21, so that the shielding housing 2 forms an insertion opening 28 to prevent mis-insertion of the docking connector. Further, the upper wall 21 and the lower wall 25 project inwardly to form the elastic piece 24 to provide an insertion force when the docking connector is inserted. The upper and lower sides of the first side wall 27 extend forward and are bent outward to form a pair of symmetrical cylindrical positioning portions 23, and a center of the positioning portion 23 is formed with a circular hole-shaped rib portion 231 in the vertical direction. The opposite inner surfaces of the two positioning portions 23 are respectively provided with a slanted arc-shaped protruding portion 232. The two positioning portions 23 are further provided with a first recessed portion 233 at the junction of the inner surface and the first side wall 27, and the two positioning portions 23 are opposite to the inner surface. The second bent portion 234 is further disposed at the end of the outwardly bent portion. The curved protruding portion 232 is provided with an arc shape between the first recessed portion 233 and the second recessed portion 234. The protrusions 232 are oppositely disposed and the vertical 孽 between the two: although near the vertex 2321, Jan.:: -r· ', '.命·Λ'·,. ' ; . . :ii . ,- The vertical distance between the oppositely disposed protrusions 232 is gradually increasing toward both sides of the vertex 2321. [0011] As shown in the second and third figures, the dustproof door 5 is substantially rectangular, and includes a plate-shaped main body portion 50, a semicircular shape that protrudes from a central position of the main body portion 50 and is folded to one side. The latching portion 51 and the rectangular operation portion 52 that is easy to be manually operated and extends from the longitudinal side of the portion 5〇. The other side of the longitudinal direction of the dustproof door is provided with a pair of symmetrically disposed cylindrical engaging portions 53, and a circular through hole 531 is provided at a central position of the end surface of the engaging portion 53. The upper and lower surfaces of the engaging portion 53 are smooth surfaces which are parallel to each other, thereby facilitating the rotation of the dustproof door. [0012] The elastic moving member 6 is formed by bending a rod-shaped elastic wire, and includes two rod-shaped portions 62 which are separated from each other in a fork shape. The same end of the rod portion is connected by a u-shaped folded portion f, and the other end of the rod portion 62 is bent upward and downward to form two pivots 63, respectively. At the time of installation, the folding form number A0101 of the secret moving member 6 page 7/20 pages M393073 is bent into the holding portion 51 of the dustproof door 5, and the pivot 63 passes through the splicing portion of the shielding case 2. The 231 is inserted into the through hole 531 of the dustproof door 5 to connect the dustproof door 5 and the shielding case 2. The pivot 63 is provided with a sufficient length to prevent the elastic moving member 6 from coming off the nip portion 231 of the shield case 2 during the rotation. [0013] In a specific operation, the operating portion 52 is applied to the dustproof door 5, and the dustproof door 5 will rotate about the elastic moving member pivot 63. Due to the presence of the protruding portion 232, the pivot 63 and the positioning portion 23 cannot be horizontally rotated. And at the apex 2321 of the projection 232, the vertical distance between the pivots 63 is closest and at this time the tension generated by the deformation of the rod 62 is maximized, thereby causing the elastic moving member 6 to automatically rotate. During the rotation process, when the elastic movement cup trajectory does not exceed the apex 2321 of the curved protrusion 232 of the shielding case 2, the dustproof door 5 automatically rebounds to reach the closed position, thereby preventing the dustproof door 5 from being Opened by mistake. When the rotational path of the elastic moving member 6 exceeds the apex 2321 of the curved protrusion 232 of the shielding case 2, the dustproof door is automatically opened to reach the open position, which can facilitate the unobstructed insertion of the docking connector. Of course, the engaging portion 53 of the dustproof door 5 may be disposed on the outer side of the positioning portion 23 of the shielding case 2, and the arcuate protruding portion 232 of the positioning portion 23 is provided on the engaging portion 53 of the dustproof door 5 [0014] As mentioned above, this creation is in line with the new patent requirements, and the patent application is filed according to law.
