It is worth mentioning that the front side edge of the top cover 31 is also provided with an upper folding piece 312 that protrudes downward, and the front side edge of the bottom cover 32 is also provided with a lower folding piece 322 that protrudes upward. The upper folding piece 312 and the lower folding piece 322 are respectively arranged in an upper and lower manner but have different structures, wherein the upper folding piece 312 is forked and provided with a rear arm 313 and a front arm 314 distributed front and back, and the lower folding piece 322 is located on the outer side of the movable door panel 42 and has a beveled edge 323 facing the docking tongue plate 113; preferably, the front side edges of the top cover 31 and the bottom cover 32 are both provided with a card slot 315, and the card slot 315 of the front side edge of the top cover 31 and the card slot 315 of the front side edge of the bottom cover 32 are arranged in upper and lower correspondence, and the card slot 315 is L-shaped, which passes through the front edges of the top cover 31 and the bottom cover 32, so that the movable door panel 42 of the rotating assembly 40 can be clamped into the card slot 315 from front to back, which can be used in conjunction with Figure 11 As shown; the lower folding piece 322 is bent and extended upward, and is blocked on the outer side of the movable door panel 42.

[0032] The rotating assembly 40 includes a spring member 41, a movable door plate 42 shielding the outside of the spring member 41, and a shielding member 43 covering the outside of the movable door plate 42. Figures 6 to 8 shown.

[0033] The spring member 41 is accommodated in the vertical groove 120 of the mounting portion 12. Preferably, the spring member 41 is a torsion spring, a top of which is provided with a positioning arm 410 extending backward, and a bottom of which is provided with a movable arm 411 extending toward the docking tongue plate 113. The extension direction of the positioning arm 410 and the extension direction of the movable arm 411 are perpendicular to each other. The positioning arm 410 is also accommodated in the vertical groove 120, and the movable arm 411 protrudes outward from the vertical groove 120 and is arranged corresponding to the horizontal groove 121. The two are located in the same horizontal plane, so that the movable arm 411 enters the horizontal groove 121 when pushed by the movable door panel 42.

[0034] The movable door panel 42 is in the form of a sheet and is placed vertically on the outside of the spring member 41. The top and bottom of the movable door panel 42 are provided with protruding shafts 420. The shafts 420 are clamped into the slots 315 on the front edges of the top cover 31 and the bottom cover 32, thereby realizing a pivotal connection with the metal shell 30, and the shafts 420 protrude from the top cover 31 and the bottom cover 32 of the metal shell 30 in the vertical direction. Preferably, the shafts 420 are formed on one side of the movable door panel 42, and the other side of the movable door panel 42 is formed with a folding piece 421 extending toward the spring member 41 and an obliquely extending edge 422 located on the lower side of the folding piece 421, and the obliquely extending edge 422 extends toward the direction of the docking tongue plate 113.

[0035] The shielding member 43 is clamped on the top cover 31 and the bottom cover 32, and is provided with a sheet-shaped main body 430, an upper folding plate 431 bent inwardly and extending from the top of the sheet-shaped main body 430, a lower folding plate 432 bent inwardly and extending from the bottom of the sheet-shaped main body 430, an inner folding plate 433 bent inwardly and extending from the inner side edge of the sheet-shaped main body 430, and an outer folding plate 434 bent inwardly and extending from the outer side edge of the sheet-shaped main body 430. The upper folding plate 431, the lower folding plate 432, the inner folding plate 433 and the outer folding plate 434 are distributed around the sheet-shaped main body 430. Preferably, the outer folding plate 434 is provided with a folding portion 435 parallel to the sheet-shaped main body 430. The folding portion 435 is located between the top cover 31 and the bottom cover 32 of the metal shell 30 and on the inner side of the side cover 33, and blocks the spring member 41 in the vertical groove 120. Preferably, the upper folding plate 431 covers the outer surface of the top cover 31, and the edge of the upper folding plate 431 is provided with an L-shaped limiting edge 436, which covers the upper part of the card slot 315. The lower folding plate 432 covers the outer surface of the bottom cover 32, and the edge of the lower folding plate 432 is also provided with an L-shaped limiting edge 436, which covers the upper part of the card slot 315. Thus, the limiting edge 436 is clamped on both sides of the shaft portion 420 to limit the shaft portion 420 in the card slot 315. Preferably, as shown in FIG. Figure 12 As shown, the shaft portion 420 protrudes upward from the top cover 31 but does not protrude from the top surface of the shielding member 43, and the shaft portion 420 protrudes downward from the bottom cover 32 but does not protrude from the bottom surface of the shielding member 43; the inner folding plate 433 abuts inwardly on the movable door plate 42 to stop the movable door plate 42, thereby preventing the movable door plate 42 from being flipped outward by external force during the process of pulling out the docking end connector.

[0036] During the docking process with the docking end connector, since the movable door plate 42 in the rotating assembly 40 can be rotated inward and reset by the spring member 41, the electrical connector of the present invention can change the shape or size of the docking frame opening as the movable door plate 42 flips, thereby presenting two docking frame openings (a first docking frame opening M1 and a second docking frame opening M2), such as Figure 13 As shown in bold lines, it can accommodate the insertion of two different types of docking end connectors. Preferably, the first docking frame M1 is formed when the movable door panel 42 is not flipped inward. In this case, the first docking frame M1 is enclosed by the top cover 31, bottom cover 32, side cover 33 of the metal shell 30, and the movable door panel 42. The folding piece 421 and obliquely extending edge 422 of the movable door panel 42 both become part of the first docking frame M1. Preferably, the second docking frame M2 is formed when the movable door panel 42 is flipped inward. In this case, the second docking frame M2 is enclosed by the top cover 31, bottom cover 32, side cover 33 of the metal shell 30, and the shielding member 43. The inner folding plate 433 of the shielding member 43 and the lower folding piece 322 of the bottom cover 32 both become part of the second docking frame M2. Preferably, the lateral dimension of the first docking frame M1 is smaller than the lateral dimension of the second docking frame M2.

[0037] As can be seen, since the movable door panel 42 is movable and is in an inward-facing state by default due to the action of the spring member 41, the first docking frame opening M1 is the docking frame opening presented by the electrical connector of the present invention in its default state, corresponding to a first docking end connector (not shown). When a second docking end connector (not shown) is inserted, the second docking end connector will push the movable door panel 42 to flip inward during the insertion process, thereby presenting a second docking frame opening M2 that matches the second docking end connector. Preferably, the first docking frame opening M1 is an HDMI (High-Definition Multimedia Interface) interface, and the second docking frame opening M2 is a DP (Display Port) interface.

[0038] To sum up, the electrical connector of the present invention optimizes the structure of the insulating body and installs a rotating component 40 at one end of the insulating body, and uses the back-and-forth flipping of the movable door plate 42 of the rotating component 40 to realize two different docking frame openings to meet the insertion of two different docking end connectors, thereby realizing multi-functional plug-in.

[0039] The above description is only the best embodiment of the present invention and does not limit the present invention in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the present invention using the above-disclosed method content without departing from the scope of the technical solution of the present invention, which all fall within the scope of protection of the claims.
