The closing plate 43 is arranged on the side of the inlet opening 11 facing away from the inner sheet metal shell 20, and the two longitudinal bars 13 are arranged on the surface of the closing plate 43 to make the closing plate 43 slide and abut against the end wall of the outer shell 10. One end of the inlet 11 far away from the surrounding frame 41 is provided with a blocking strip 14, and the blocking strip 14 extends upwards to the lower part of the button column 35. The opposite ends of the closing plate 43 slidably abut against the stop bar 14 and the abutting convex portion, respectively. Rectangular hanging holding strips are arranged at two opposite ends of the top of the closing plate 43 in a protruding mode respectively, the two hanging holding strips are respectively a first hanging holding strip 431 and a second hanging holding strip 433, the first hanging holding strip 431 is supported above the button column 35, and the second hanging holding strip 433 is supported on the top of the surrounding frame 41. The bottom of the closing plate 43 is concavely provided with a rectangular groove 438 in the middle. The upper side of the rectangular groove 438 is formed with a friction edge. By providing the closing plate 43, it is possible to close the inlet port 11 to shield dust when not in use, and to insert the USB plug into the inlet port 11 and support the closing plate 43 when in use.

For example, in one embodiment, the button post 35 is cylindrical, and has a rising slope 351 formed thereon and a retaining notch 352, the rising slope 351 is adjacent to the end wall of the housing 10, a rising arc 353 is formed on the side of the rising slope 351 facing the surrounding frame 41, and the first hanging strip 431 of the closing plate 43 is supported on the rising slope 351. The temporary holding notch 352 is located at one end of the button post 35 far away from the housing 10, a straight wall section 3521 and an upward inclined surface 3523 are formed in the temporary holding notch 352, the straight wall section 3521 is perpendicular to the axis of the button post 35, the upward inclined surface 3523 extends along the bottom of the straight wall section 3521 in a direction away from the housing 10 in an inclined manner, a rotation driving groove 350 is further formed in the button post 35, the rotation driving groove 350 is located on one side of the button post 35 facing the surrounding frame 41, and the rotation driving groove 350 is located on the upper portion of the upward inclined surface 3523 of the temporary holding notch 352. The rotary driving groove 350 includes a flat bottom surface 3501 and a driving surface 3503, the flat bottom surface 3501 is parallel to the horizontal plane, one end of the flat bottom surface 3501 extends to the middle of the upward inclined surface 3523, the driving surface 3503 is perpendicular to the flat bottom surface 3501, one end of the driving surface 3503 extends to the middle of the upward inclined surface 3523, and the other end extends in a direction away from the housing 10. The distance between the driving surface 3503 and the surrounding frame 41 gradually decreases in a direction away from the housing 10. The lowest position of the rising slope 351 is higher than the lowest position of the temporary holding notch 352. The distance between the top edge and the bottom edge of the access port 11 is defined as the width, and the width of the access port 11 is greater than the thickness of the USB plug.

For example, when the USB socket 21 needs to be inserted, the USB plug is forcibly inserted into the USB socket 21 of the inner sheet metal shell 20, and the moving distance between the end wall of the outer shell 10 and the end wall of the inner sheet metal shell 20 is small, which does not greatly affect the insertion of the USB plug. Thereafter, the button post 35 is adapted to move toward the inner sheet metal shell 20 under an external force (i.e., a first pressing by a human hand) to cause the guide post 36 to move along the lead-in slot 3351 to the final end of the lead-in slot 3351 and to return under the action of the compression spring 37 (at which time the button post 35 has been released) to move to the recessed portion 3395 of the guide block 339, during which the first hanging bar 431 of the closing plate 43 is adapted to slide along the ascending slope 351 of the button post 35 into the temporary cut-out slot 352 and move to the ascending slope 3523, and finally return to the lowest position of the temporary cut-out slot 352 (i.e., at the straight wall section 3521, at which time the button post 35 has been released, during which the first hanging bar 431 does not enter the rotation driving slot 350), so that the position of the closing plate 43 is lowered and supported by the tail portion of the USB plug, so that the tail portion of the USB plug is located in the rectangular slot 438 (the tail portion of the USB plug is smaller in size and, the periphery of the USB plug is sealed by the sealing plate 43 and the friction edge is abutted against the tail of the USB plug, so that the defects of accidental collision of the USB plug, electric leakage of the USB plug and the like can be avoided, and the USB plug can be prevented from loosening under the accidental collision by the friction edge. It will be appreciated that in the above process, only the button post 35 moves axially along the button post 35, and the above movement of the first hanging bar 431 is only a relative movement with respect to the button post 35.

When it is desired to remove the USB plug, the button post 35 is further configured to move toward the inner sheet metal shell 20 under an external force (i.e., a second pressing by a human hand), so as to cause the guiding post 36 to move along the advanced groove 3353 to reach the final end of the advanced groove 3353 and return to the final end of the retracted groove 3354 (at which time the button post 35 has been released) under the action of the compression spring 37, during which the guiding post 36 is configured to toggle the thrust plate 22 to remove the USB plug and release the thrust plate 22, during which the first hanging strip 431 of the closing plate 43 is configured to slide along the upward inclined surface 3523 of the button post 35 into the rotational driving groove 350 (the advanced groove 3353 is deeper than the temporary retracted groove 3352, so that the first hanging strip 431 can reach the rotational driving groove 350 during this pressing), and abut against the driving surface 3503 of the rotational driving groove 350 to cause the button post 35 to rotate relative to the connecting rod 328 (at this time, the closing plate 43 is laterally moved toward the enclosure frame 41 and partially enters the sliding gap due to the abutting force of the rotational post), eventually, the end of the first hanger bar 431 disengages from the driving surface 3503 and slides along the circumference of the button post 35 to above the button post 35. The button column 35 is released, at this time, the first hanging strip 431 is used for moving along the axial direction of the button column 35 in the releasing and returning action of the button column 35, so that the first hanging strip 431 is returned to the rising arc 353 of the button column 35, the button column 35 is rotated and returned to the original position under the action of the torsion spring to allow the first hanging strip 431 to move transversely to the rising inclined surface 351 of the button column 35 under the thrust action of the plurality of thrust springs 44, so that the height of the closing plate 43, namely the original height position of the closing plate 43 can be increased, so as to completely expose the access opening 11, at this time, the USB plug can be pulled out from the completely exposed access opening 11 very easily because the USB plug is already pulled out by the thrust plate 22. It will be appreciated that in the above process, only the button post 35 moves axially along the button post 35, and the movement of the first hanging bar 431 only moves relatively to the button post 35.

By providing the sealing member 40, the sealing plate 43 can be put down after the USB plug is inserted to block the periphery of the USB plug and position the tail of the USB plug by using the friction edge, thereby preventing dust, electric leakage, and collision to position the USB plug. When the push button column 35 is pressed, the push plate 22 can be pushed by the guide column 36 to push the USB plug out, (because when the push plate 22 is pushed, the guide column 36 is in the process of returning in the withdrawing groove 3354, at this time, the first hanging strip 431 has already left the rotary driving groove 350 to rise to the top of the push button column 35 and is in the process of returning to the original position, that is, the first hanging strip 431 has already driven the closing plate 43 to move upwards to completely expose the access opening 11, so the closing plate 43 does not affect the pulling out of the USB plug, because the opposite ends of the closing plate 43 are respectively limited by the blocking strip 14 and the sliding strip 42, the closing plate 43 can also rise smoothly without deflection due to the unidirectional rising of the first hanging strip 431 only). The sealing assembly 40 is interlocked with the button assembly 30, and can open the access opening 11 in advance when the USB plug is pushed out, thereby greatly improving the pulling efficiency.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
