Description

Technical Field

[0001] This application relates to the field of charging interface technology, and in particular to a charging interface protection device and a connector equipped with the charging interface protection device. Background Technology

[0002] Charging interfaces are widely used in various types of new energy vehicles, communications, computers, and other fields. Existing charging interfaces are generally protected by a protective device, which includes a protective cover, a locking mechanism, and a button. Both the button and the locking mechanism are located on the outer periphery of the charging interface. The protective cover covers the charging interface to provide waterproofing and dustproofing, and the protective cover and the locking mechanism can be locked or unlocked. Pressing the button from the outer periphery of the charging interface unlocks the locking mechanism from the protective cover.

[0003] However, since the existing charging port's protective device is pressed to unlock on the outer periphery, it is inconvenient to operate the button in scenarios where the outer periphery of the charging port is small, and users may damage the button due to accidental operation, causing the protective device to fail. Summary of the Invention

[0004] The purpose of this application is to provide a charging interface protection device and a connector equipped with the charging interface protection device.

[0005] This application provides a charging interface protection device, which includes a connector, a cover mechanism, and a locking mechanism. The connector includes a locking element; the cover mechanism includes a cover and a driving member, one end of the cover is rotatably connected to the connector, and the driving member is connected to the connector and the cover, and the driving member is used to drive the cover to rotate relative to the connector; the locking mechanism includes a locking element and an operating element, the locking element is disposed on the cover mechanism, and the operating element is disposed on the side of the charging interface protection device opposite to the connector. The locking element can be locked to the locking element, and the operating element can be operated from the side of the cover mechanism opposite to the connector to unlock the locking element from the locking element.

[0006] This application also provides a connector including a charging interface protection device. The charging interface protection device includes a connector base, a cover mechanism, and a locking mechanism. The connector base includes a locking element. The cover mechanism includes a cover and a driving member. One end of the cover is rotatably connected to the connector base. The driving member is connected to the connector base and the cover. The driving member is used to drive the cover to rotate relative to the connector base. The locking mechanism includes a locking element and an operating element. The locking element is disposed on the cover mechanism. The operating element is disposed on the side of the charging interface protection device opposite to the connector base. The locking element can be locked to the locking element. The operating element can be operated from the side of the cover mechanism opposite to the connector base to unlock the locking element from the locking element.

[0007] The charging interface protection device of this application has a locking fastener on its connector base, a cover rotatably connected to the connector base, a drive unit connected between the connector base and the cover, a locking member located on the cover mechanism, and an operating member located on the side of the charging interface protection device away from the connector base. When locking is required, the operator pushes the side of the cover away from the connector base, causing the cover to rotate relative to the connector base and move closer to the locking fastener until the locking member is locked to the fastener. When unlocking is required, the operator operates the operating member from the side of the cover mechanism away from the connector base, causing the locking member to unlock from the fastener, and the cover rotates relative to the connector base and away from the locking fastener under the drive of the drive unit. Since both locking and unlocking of the charging interface protection device are located on the side of the cover away from the connector base, the operating member is easy to operate even in scenarios where the peripheral space of the charging interface protection device is small, and damage to the operating member due to operator error is avoided, preventing the charging interface protection device from malfunctioning.

Outlet 2406; insert the two guide sliders 2625 of the operating member 262 into the two guide slots 2408 of the cover 2401 respectively, so that the first pushing surface 2622 of the pushing part 2621 is in contact with the first sliding surface 2604; cover the operating member 262 with the first positioning member 244, so that the first pressing part 2623 is inserted into the guide hole 2442, and connect the first positioning member 244 to the cover 2401. The first positioning member 244 and the cover 2401 can be connected by, but is not limited to, welding or gluing. A fixed connection is established, with the first stop 2624 abutting against the positioning step 2443; the first sealing cover 246 covers the connecting ring 2445, so that the snap-fit ​​edge 2465 is sealed and snapped into the snap-fit ​​ring groove 2446, and the top piece 2462 is attached to the first pressing part 2623; the driving member 241 is installed on the rotating part 2403, so that the inner cavity of the rotating cylinder 2412 is aligned with the first rotating hole 2409; the rotating part 2403 and the driving member 241 are accommodated in the connecting space 2245 of the connecting seat 22, so that the second The shaft hole 2246 is aligned with the first rotating hole 2409; the rotating shaft 247 is inserted into the inner cavity of the second shaft hole 2246, the first rotating hole 2409 and the rotating cylinder 2412, and the two elastic feet 2414 elastically abut against the connecting seat 22 and the cover 240 respectively. The driving member 241 drives the cover 240 to rotate relative to the connecting seat 22 until the rotating part 2403 stops at the stop block 2247; the sealing ring 243 is positioned in the annular groove 2400 so that the sealing ring 243 is sealed and fitted onto the sealing part 2402.

[0058] like Figure 1 and Figure 2 As shown, the mounting panel 50 is sleeved onto the connector body 60, so that the cavity 62 passes through the mounting hole 52. The mounting panel 50 is stacked on the fixing plate 66, and the four through holes 54 are respectively aligned with the four fixing holes 662. The connecting plate 221 is stacked on the surface of the mounting panel 50 away from the fixing plate 66, so that the cavity 62 is inserted into the inner cavity 2230 of the guide tube 223, and the four connecting holes 2212 are respectively aligned with the four through holes 54. Four locking fasteners, such as screws, pass through the four connecting holes 2212 and the four through holes 54 and are locked into the four fixing holes 662, so that the charging interface protection device 20, the mounting panel 50 and the connector body 60 are connected as one unit, and the locking member 260 is locked to the locking protrusion 2203.

[0059] like Figure 1 , Figure 4 and Figure 6 As shown, when the cover 2401 needs to be opened, the operator presses the top piece 2462 of the first sealing cover 246. The top piece 2462 elastically deforms and pushes against the first pressing part 2623, causing the operating member 262 to slide in the guide hole 2442 along the first direction. The two guide blocks 2625 can slide into the two guide grooves 2408 of the cover 2401 respectively. The first pushing surface 2622 of the pushing part 2621 slides against the first sliding surface 2604 to drive the locking member 260 in the guide groove 2404 along the second direction. When the locking member 260 slides against the first elastic member 2600, it undergoes elastic deformation. The locking part 2602 slides away from the locking member 220 until it disengages from the locking protrusion 2203. The driving member 241 drives the cover 240 to rotate along the pivot 247 away from the locking member 220 until the cover 240 stops at the stop block 2247. The cover 240 opens the inner cavity 2230 of the guide tube 223 to facilitate the insertion of the plug into the insertion core 64. When the pressure on the first sealing cover 246 is released, the first elastic member 2600 elastically resets and drives the locking member 260 to slide back to its original position. The first sliding surface 2604 slides against the first abutting surface 2622 to make the operating member 262 slide back to its original position away from the connecting seat 22.

[0060] When it is necessary to lock the charging interface protection device 20, the plug to be inserted is pulled out of the connector 100. The operator pushes the first positioning member 244 away from the side of the connector 22, so that the cover 240 rotates around the pivot 247 and faces the locking member 220. The abutment surface 2609 slides against the guide surface 2205, so that the locking member 260 slides away from the locking member 220 along the guide groove 2404. The first elastic member 2600 is pressed by the locking member 260 and undergoes elastic deformation until the locking part 2602 passes the guide surface 2205. The first elastic member 2600 elastically resets and drives the locking member 260 towards the locking member 220 until the locking part 2602 is locked to the locking surface 2206 of the locking protrusion 2203. At this time, the sealing ring 243 is sealed between the cover 240 and the guide tube 223, the first elastic member 2600 is sealed between the first positioning member 244 and the cover 240 to seal the outlet 2406; the first sealing cover 246 completely seals the connecting ring 2445 to seal the guide hole 2442.

[0061] The operating element 262 of the connector 100 of this application is disposed on the side of the cover 2401 away from the connector seat 22. This avoids the operating element 262 being disposed on the peripheral wall of the cover 2401, which would increase the radial dimension of the guide tube 223 of the charging interface protection device 20 and reduce the radial dimension of the charging interface protection device 20. In other words, it can reduce the radius L of the charging interface protection device 20. Furthermore, the first sealing cover 246 is located on the surface of the cover 2401 away from the connector seat 22, making the unlocking interface intuitive and convenient for the operator to unlock or lock. Secondly, since the first sealing cover 246 seals the guide hole 2442 and the first elastic element 2600 also seals the outlet 2406, it can effectively prevent water, mud, dust and other debris from entering the interior of the cover 240, thereby avoiding affecting the normal operation of the locking structure.

[0062] Specifically, by setting the first sealing cover 246, water, mud, dust and other debris can be prevented from entering the space between the operating part 262 and the cover 240 through the guide hole 2442. On the one hand, this ensures that the operator can press the operating part 262 normally and avoids malfunction. On the other hand, it can prevent debris from entering and causing the spring to rust, be damaged or lose elasticity. At the same time, it ensures that the pushing action between the operating part 262 and the locking part 260 is reliable and that the locking part 260 slides smoothly in the guide groove 2404, thereby maintaining the overall functional stability of the locking structure.

[0063] In addition, the cooperation of the sealing ring 243, the cover 240 and the guide tube 223 can effectively prevent water, mud, dust and other debris from entering the plug core 64, ensuring the normal operation of the connector.

[0064] like Figures 7-10As shown, the structure of the connector 100a provided in the second embodiment of this application is similar to that of the connector 100 provided in the first embodiment. The difference is that the specific structure of the connector 22a in the second embodiment is slightly different from that of the connector 22 in the first embodiment. Specifically, the connector 22a in the second embodiment is based on the connector 22 in the first embodiment with the addition of a cavity 62. That is, the connector 22a is based on the connector 22 in the first embodiment with the addition of a rectangular dashed frame portion. In other words, the connector 22a and the cavity 62 are an integral structure. The connector 22a in the second embodiment includes a connecting plate 221, a guide tube 223, a connecting part 224, and a cavity 62. The guide tube 223 is located in the middle of the connecting plate 221, and the two opposite ends of the guide tube 223 along its axial direction pass through the opposite sides of the connecting plate 221. One end of the cavity 62 is connected to the end of the guide tube 223 away from the covering mechanism 24. The cavity 62 and the guide tube 223 are coaxial. The cavity 62 is used to position the insertion core 64. Specifically, the cavity 62 includes a first cylindrical body 621 and a second cylindrical body 623 connected to one end of the first cylindrical body 621. The first cylindrical body 621 and the second cylindrical body 623 are coaxial. The inner diameter of the first cylindrical body 621 is the same as the inner diameter of the guide tube 223, and the inner diameter of the first cylindrical body 621 is larger than the inner diameter of the second cylindrical body 623, so as to form a positioning platform 624 between the first cylindrical body 621 and the second cylindrical body 623. A positioning ring 625 is provided on the inner circumferential surface of the second cylindrical body 623, and the positioning ring 625 surrounds the second cylindrical body 623. A ring is arranged around the circumference of the cylinder 623; the insertable rubber core 64 is positioned in the inner cavity of the cavity 62. Specifically, a retaining ring 642 is provided at one end of the outer circumference of the insertable rubber core 64. The retaining ring 642 is arranged around the circumference of the insertable rubber core 64. At least one elastic hook 644 is provided at the end of the insertable rubber core 64 near the retaining ring 642. Optionally, two elastic hooks 644 are provided at the end of the insertable rubber core 64 near the retaining ring 642. The two elastic hooks 644 are located at opposite ends of the radial direction of the insertable rubber core 64.

[0065] Understandably, the connector 22a and the cavity 62 are an integral structure, that is, the connector 22a and the cavity 62 are injection molded from plastic material into one piece.

[0066] like Figure 9 and Figure 11As shown, when the insert core 64 needs to be installed in the cavity 62, one end of the insert core 64 with the elastic hook 644 is inserted into the inner cavity 2230 of the guide tube 223 until the retaining ring 642 abuts against the positioning platform 624 and the elastic hook 644 is engaged with the positioning ring 625, so that the insert core 64 is positioned in the inner cavity of the cavity 62. When the connector 100a is installed on the mounting panel 50, the mounting panel 50 is sleeved on the charging interface protection device 20, so that the connecting plate 221 is attached to the mounting panel 50, the four connecting holes 2212 are aligned with the four through holes 54, and the four locking fasteners, such as screws, pass through the four through holes 54 and are locked into the four connecting holes 2212, so that the connector 100a is positioned on the mounting panel 50.

[0067] When the cover 2401 needs to be opened, the operator presses the top piece 2462 of the first sealing cover 246. The top piece 2462 elastically deforms and pushes the operating member 262 to slide in the guide hole 2442 along the first direction. The two guide blocks 2625 can slide into the two guide grooves 2408 of the cover 2401 respectively. The first pushing surface 2622 of the pushing part 2621 slides against the first sliding surface 2604 to drive the locking member 260 to slide along the guide groove 2404. In the second direction of sliding, the locking member 260 pushes against the first elastic member 2600 and undergoes elastic deformation. The locking part 2602 slides away from the end of the locking member 220 until the locking part 2602 disengages from the locking protrusion 2203. The driving member 241 drives the cover 240 to rotate away from the locking member 220 until the cover 240 opens the inner cavity 2230 of the guide tube 223, so that the plug to be inserted can pass through the inner cavity 2230 and be inserted into the plug core 64.

[0068] In the second embodiment, the cavity 62 and the connecting seat 22a of the connector 100a are integrated, reducing the number of components, lowering manufacturing costs, and providing better sealing. Secondly, the operating member 262 is located on the side of the cover 2401 away from the connecting seat 22, avoiding the increase in the radial dimension of the guide tube 223 of the charging interface protection device 20a due to the operating member 262 being located on the peripheral wall of the cover 2401, thus reducing the radial dimension of the charging interface protection device 20. Furthermore, the first sealing cover 246 is located on the surface of the cover 2401 away from the connecting seat 22, making the unlocking interface intuitive and convenient for the operator to unlock or lock. In addition, since the first sealing cover 246 seals the guide hole 2442, and the first elastic member 2600 also seals the outlet 2406, it can effectively prevent water, mud, dust, and other debris from entering the interior of the cover 240, thereby preventing the normal operation of the locking structure from being affected.

[0069] like Figures 12-15As shown, the structure of the connector 100b provided in the third embodiment of this application is similar to that of the connector 100 provided in the first embodiment. The difference is that the specific structure of the connector 22b in the third embodiment is slightly different from that of the connector 22 in the first embodiment. Specifically, the connector 22b in the third embodiment is based on the connector 22 in the first embodiment with the addition of a cavity 62 and a plug core 64. That is, the connector 22b is based on the connector 22 in the first embodiment with the addition of the dotted frame portion. The connector 22b, the cavity 62 and the plug core 64 are an integral structure. The connecting seat 22b in the third embodiment includes a connecting plate 221, a guide tube 223, a connecting part 224, a cavity 62, and a plug-in core 64. The guide tube 223 is located in the middle of the connecting plate 221, and the two opposite ends of the guide tube 223 along its axial direction pass through the opposite sides of the connecting plate 221 respectively. One end of the cavity 62 is connected to the end of the guide tube 223 away from the covering mechanism 24. The cavity 62 and the guide tube 223 are coaxial. The plug-in core 64 is housed in the inner cavity of the cavity 62 and the inner cavity of the guide tube 223, and the plug-in core 64 is connected to the cavity 62. Specifically, the cavity 62 includes a first cylindrical body 621 and a second cylindrical body 623 connected to one end of the first cylindrical body 621. The first cylindrical body 621 and the second cylindrical body 623 are coaxial. The inner diameter of the first cylindrical body 621 is the same as the inner diameter of the guide tube 223, and the inner diameter of the first cylindrical body 621 is larger than the inner diameter of the second cylindrical body 623. The outer peripheral surface of the insertion core 64 is connected to the connection between the first cylindrical body 621 and the second cylindrical body 623, so that the insertion core 64 is positioned in the inner cavity of the cavity 62. The insertion core 64 is provided with a first positioning hole and a second positioning hole spaced apart from each other along its axial direction. The first positioning hole is used to position the power terminal 2481, and the second positioning hole is used to position the signal terminal 2483.

[0070] Understandably, the connector 22b, cavity 62, and plug-in core 64 are an integral structure, meaning that the connector 22b, cavity 62, and plug-in core 64 are injection molded from plastic material into one piece.

[0071] like Figure 12 and Figure 13 As shown, when the connector 100b is installed onto the mounting panel 50, the mounting panel 50 is fitted onto the charging interface protection device, so that the connecting plate 221 is attached to the mounting panel 50, the four connecting holes 2212 are aligned with the four through holes 54, and the four fasteners, such as screws, pass through the four through holes 54 and are locked into the four connecting holes 2212, so that the connector 100b is positioned on the mounting panel 50.

[0072] like Figures 14-16As shown, when the cover 2401 needs to be opened, the operator presses the top piece 2462 of the first sealing cover 246. The top piece 2462 elastically deforms and pushes the operating member 262 to slide in the guide hole 2442 along the first direction. The two guide blocks 2625 can slide into the two guide grooves 2408 of the cover 2401 respectively. The first pushing surface 2622 of the pushing part 2621 slides against the first sliding surface 2604 to drive the locking member 260 in the guide groove 2404. Sliding along the second direction, the locking member 260 pushes against the first elastic member 2600 and undergoes elastic deformation. The locking part 2602 slides away from the end of the locking member 220 until the locking part 2602 disengages from the locking protrusion 2203. The driving member 241 drives the cover 240 to rotate away from the locking member 220 until the cover 240 opens the inner cavity 2230 of the guide tube 223, so that the plug to be inserted can pass through the inner cavity 2230 and be inserted into the insertion core 64.

[0073] In the third embodiment, the connector 100b's cavity 62, connector seat 22b, and plug core 64 are integrated into a single structure, reducing the number of components, lowering manufacturing costs, and providing better sealing. Secondly, the operating member 262 is located on the side of the cover 2401 away from the connector seat 22, avoiding the increase in the radial dimension of the charging interface protection device 20b's guide tube 223 due to the operating member 262 being located on the peripheral wall of the cover 2401, thus reducing the radial dimension of the charging interface protection device 20b. Furthermore, the first sealing cover 246 is located on the surface of the cover 2401 away from the connector seat 22, making the unlocking interface intuitive and convenient for the operator to unlock or lock. In addition, since the first sealing cover 246 seals the guide hole 2442, and the first elastic member 2600 also seals the outlet 2406, it can effectively prevent water, mud, dust, and other debris from entering the interior of the cover 240, thereby preventing the normal operation of the locking structure from being affected.

[0080] like Figures 19-21As shown, when the cover 2401 needs to be opened, the operator pushes the outer sleeve 2455b to move the operating member 262 away from the locking member 220, so as to drive the rotating plate 261 to rotate along the guide arc surface 2411, so that the locking block 263 slides away from the locking member 220, the second elastic member 2415 is compressed and elastically deformed until the locking part 2602 disengages from the locking port 2631; the driving member 241 drives the cover 240 to rotate along the rotating shaft 247 away from the locking member 220 until the cover 240 stops at the stop block 2247, and the cover 240 opens the inner cavity 2230 of the guide tube 223 to facilitate the plug to be inserted through the inner cavity 2230 and into the insertion core 64.

[0081] When it is necessary to lock the charging interface protection device 20c, the plug to be inserted is pulled out of the connector 100. The operator pushes the first positioning member 244 away from the side of the connector 22, so that the cover 240 rotates around the pivot 247 and faces the locking member 220. The abutment surface 2609 slides against the guide surface 2205, so that the locking member 260 slides away from the locking member 220 along the guide groove 2404. The first elastic member 2600 is pressed by the locking member 260 and undergoes elastic deformation until the locking part 2602 passes the guide surface 2205. The first elastic member 2600 elastically resets and drives the locking member 260 towards the locking member 220 until the locking part 2602 is locked to the locking surface 2206 of the locking protrusion 2203. At this time, the sealing ring 243 is sealed between the cover 240 and the guide tube 223, and the first elastic member 2600 is sealed between the first positioning member 244 and the cover 240 to seal the outlet 2406; the first sealing cover 246 completely seals the connecting ring 2445 to seal the guide hole 2442. Releasing the pushing force on the first positioning member 244, the second elastic member 2415 elastically resets, driving the locking member 260c to rotate and reset along the guide arc surface 2411, thereby moving and resetting the operating member 262 and the locking block 263.

[0082] The operating element 262 of the connector 100c in this application is disposed on the side of the cover 2401 away from the connector seat 22. This avoids the operating element 262 being disposed on the peripheral wall of the cover 2401, which would increase the radial dimension of the guide tube 223 of the charging interface protection device 20c and reduce the radial dimension of the charging interface protection device 20c. Furthermore, the second sealing cover 2455 is located on the surface of the cover 2401 away from the connector seat 22, making the unlocking interface intuitive and convenient for the operator to unlock or lock. Secondly, since the first sealing cover 246 seals the guide hole 2442 and the first elastic element 2600 also seals the outlet 2406, it can effectively prevent water, mud, dust and other debris from entering the interior of the cover 240, thereby avoiding affecting the normal operation of the locking structure.

[0083] Specifically, by setting the first sealing cover 246, water, mud, dust and other debris can be prevented from entering the space between the operating part 262 and the cover 240 through the guide hole 2442. On the one hand, this ensures that the operator can press the operating part 262 normally and avoids malfunction. On the other hand, it can prevent debris from entering and causing the spring to rust, be damaged or lose elasticity. At the same time, it ensures that the pushing action between the operating part 262 and the locking part 260 is reliable and that the locking part 260 slides smoothly in the guide groove 2404, thereby maintaining the overall functional stability of the locking structure.

[0084] In addition, the cooperation of the sealing ring 243, the cover 240 and the guide tube 223 can effectively prevent water, mud, dust and other debris from entering the cavity 64, ensuring the normal operation of the connector.

[0085] In other embodiments, a cavity 62 is added to the connecting seat 22 in the fourth embodiment, meaning that the connecting seat 22 and the cavity are an integral structure. Optionally, the connecting seat 22 and the cavity are injection molded from plastic material as a single unit.

[0086] In other embodiments, a cavity and a plug-in core are added to the connector 22 in the fourth embodiment, meaning that the connector 22, the cavity, and the plug-in core are integrated into one structure. Optionally, the connector 22, the cavity, and the plug-in core are injection molded from plastic material as a single unit.

[0087] Please refer to the following: Figures 22-27 The connector 100d provided in the fifth embodiment of this application has a structure similar to that of the connector 100 provided in the first embodiment, except that the specific structure of the locking member 260b in the fifth embodiment is different from that of the locking member 260 in the first embodiment. Specifically, the locking member 260b includes a sliding cover 265, a locking block 263, and an operating block 266. The sliding cover 265 is slidably connected to the side of the cover 2401 away from the connector seat 22. The locking block 263 is located on the outer edge of the sliding cover 265, and the operating block 266 is located on the side of the sliding cover 265 away from the connector seat 22. The locking block 263 can be locked to the locking fastener 220. When the operator pushes the operating block 266 to slide relative to the cover 2401 towards the end away from the locking fastener 220, the sliding cover 265 slides towards the end away from the locking fastener 220, and the locking block 263 moves away from the locking fastener 220 along with the sliding cover 265 until the locking block 263 disengages from the locking protrusion 2203.

[0088] In this embodiment, a guide strip 248 is provided on the surface of the cover 2401 facing away from the connecting seat 22. The length direction of the guide strip 248 is parallel to the radial direction of the sealing part 2402, and one end of the guide strip 248 faces the rotating part 2403. A first groove is provided on the surface of the sliding cover 265 facing the cover 2401.

[0089] 2651, the opposite ends of the first slide groove 2651 respectively pass through the outer peripheral surface of the sliding cover 265, and the guide strip 248 is slidably accommodated in the first slide groove 2651. The operating block 266 protrudes from the surface of the sliding cover 265 opposite to the first slide groove 2651, and the locking block 263 is disposed at one end of the first slide groove 2651. Specifically, the opposite two sides of the guide strip 248 are respectively provided with second slide grooves 2482, and the sliding cover 265 is respectively provided with slide strips 2653 on the opposite two sides of the first slide groove 2651. The two slide strips 2653 are slidably accommodated in the two second slide grooves 2482 respectively. The first elastic member 2600 is connected to the cover 2401 and the locking member 260b, and the first elastic member 2600 has a first pre-elastic force to drive the locking member 260b to lock onto the locking member 220. Specifically, the guide strip 248 has a second clearance groove 2484 at one end away from the locking protrusion 2203. The length direction of the second clearance groove 2484 is parallel to the length direction of the guide strip 248. The locking block 263 is slidably accommodated in the second clearance groove 2484. The first elastic member 2600 is accommodated in the second clearance groove 2484. One end of the first elastic member 2600 abuts against the end face of the second clearance groove 2484 away from the locking block 263, and the other end of the first elastic member 2600 abuts against the locking block 263. The cover 2401 has a stop groove 2485 at one end away from the rotating part 2403. The stop groove 2485 communicates with the second clearance groove 2484. In this embodiment, the cover 2401 has stop grooves 2485 on opposite sides of the second clearance groove 2484 at one end away from the rotating part 2403, and the two stop grooves 2485 communicate with the second clearance groove 2484 respectively. One end of the locking block 263 protrudes from the outer peripheral surface of the sliding cover 265. The end of the locking block 263 facing away from the sliding cover 265 has a locking opening 2631, into which the locking protrusion 2203 of the locking member 220 can be locked. A second positioning post 2633 is provided on the end face of the locking block 263 facing away from the locking opening 2631, and one end of the first elastic member 2600 is positioned on the second positioning post 2633. A stop strip 2635 is provided on the side of the locking block 263. The locking member 260b can slide relative to the cover 2401 until the stop strip 2635 stops in the stop groove 2485. Specifically, two stop strips 2635 are provided on opposite sides of the locking block 263, and the locking member 260b can slide relative to the cover 2401 until the two stop strips 2635 respectively stop in the two stop grooves 2485. The sliding cover 265 has a raised rib 2636 on the surface facing the cover 2401. The raised rib 2636 can reduce the frictional resistance when the locking member 260b slides relative to the cover 2401, and avoid the problem of uneven sliding of the sliding cover 265 relative to the locking member 260b due to uneven force.

[0090] When assembling the charging interface protection device 20d, one end of the first elastic member 2600 is positioned on the second positioning post 2633. The two sliding strips 2653 of the locking member 260b, located away from the locking block 263, are inserted from the end away from the rotating part 2403 into the two second sliding grooves 2482, causing the first elastic member 2600 to insert into the second clearance groove 2484 until the two stop strips 2635 respectively abut against the opposite sides of the second clearance groove 2484. The sliding cover 265 is then pushed relative to the guide strip 248 towards the rotating part 2403, and the two stop strips... 2635 undergoes elastic deformation until the two stop bars 2635 are respectively aligned with the two stop grooves 2485. The two stop bars 2635 elastically reset and abut against the sides of the two stop grooves 2485. The first elastic member 2600 is elastically clamped between the end faces of the locking block 263 and the second clearance groove 2484. The first elastic member 2600 has a pre-elastic force that pushes the locking block 263 to slide towards the locking fastener 220, so that the locking block 263 extends out of the second clearance groove 2484, and the two stop bars 2635 respectively stop against the sides of the two stop grooves 2485. The rotating part 2403 and the driving member 241 are housed in the connecting space 2245 of the connecting seat 22, so that the second shaft hole 2246 is directly opposite the first rotating hole 2409; the rotating shaft 247 is inserted into the inner cavity of the second shaft hole 2246, the first rotating hole 2409 and the rotating cylinder 2412, and the two elastic feet 2414 elastically abut against the connecting seat 22 and the cover 240 respectively. The driving member 241 drives the cover 240 to rotate relative to the connecting seat 22 until the rotating part 2403 stops at the stop block 2247; the sealing ring 243 is positioned in the annular groove 2400 so that the sealing ring 243 is sealed and fitted onto the sealing part 2402.

[0091] Mounting panel 50 is fitted onto connector body 60, so that cavity 62 passes through mounting hole 52. Mounting panel 50 is stacked on fixing plate 66, and four through holes 54 are respectively aligned with four fixing holes 662. Connecting plate 221 is stacked on the surface of mounting panel 50 away from fixing plate 66, so that cavity 62 is inserted into inner cavity of guide tube 223, and four connecting holes 2212 are respectively aligned with four through holes 54. Four locking fasteners, such as screws, pass through four connecting holes 2212 and four through holes 54 and are locked into four fixing holes 662, so that charging interface protection device 20d, mounting panel 50 and connector body 60 are connected as one unit, and locking member 260 is locked to locking protrusion 2203.

[0092] like Figure 24 , Figure 26 and Figure 28As shown, when the cover 2401 needs to be opened, the operator pushes the operating block 266 to slide it away from the locking fastener 220, so that the sliding cover 265 slides relative to the cover 2401 and approaches the rotating part 2403. The locking block 263 slides away from the locking fastener 220 along with the sliding cover 265 until the locking block 263 disengages from the locking protrusion 2203. The driving member 241 drives the cover 240 to rotate along the rotating shaft 247 away from the locking fastener 220 until the cover 240 stops at the stop block 2247. The cover 240 opens the inner cavity 2230 of the guide tube 223 so that the plug to be inserted can pass through the inner cavity 2230 and be inserted into the insertion core 64.

[0093] When it is necessary to lock the charging interface protection device 20d, the plug to be inserted is pulled out of the connector 100d. The operator pushes the operating block 266 to rotate the cover 2401 relative to the connector 22 toward the locking fastener 220. The locking block 263 slides against the guide surface 2205 away from the end face of the rotating part 2403, causing the locking member 260b to slide away from the locking fastener 220 along the second slide groove 2482. The first elastic member 2600 is pressed by the locking member 260b and undergoes elastic deformation until the locking block 263 passes the guide surface 2205. The first elastic member 2600 elastically resets and drives the locking member 260b toward the locking fastener 220 until the locking surface 2206 locks into the locking port 2631. At this time, the sealing ring 243 is sealed between the sealing part 2402 and the guide tube 223, and the first elastic member 2600 is sealed between the locking block 263 and the cover 2401. When the pushing force on the operating block 266 is released, the first elastic element 2600 elastically resets and drives the locking element 260d to slide and reset along the second slide groove 2482, thereby causing the locking block 263 to extend out of the second clearance groove 2484.

[0094] The operating block 266 of the connector 100d in this application is disposed on the side of the cover 2401 away from the connector seat 22. This avoids the radial dimension of the guide tube 223 of the charging interface protection device 20d being increased due to the operating block 266 being disposed on the peripheral wall of the cover 2401, and reduces the radial dimension of the charging interface protection device 20d. Furthermore, the operating block 266 is located on the surface of the cover 2401 away from the connector seat 22, making the unlocking interface intuitive and convenient for the operator to unlock or lock.

[0095] In other embodiments, a cavity 62 is added to the connecting seat 22 in the fifth embodiment, meaning that the connecting seat 22 and the cavity are an integral structure. Optionally, the connecting seat 22 and the cavity are injection molded from plastic material as a single unit.

[0096] In other embodiments, a cavity and a plug-in core are added to the connector 22 in the fifth embodiment, meaning that the connector 22, the cavity, and the plug-in core are integrated into one structure. Optionally, the connector 22, the cavity, and the plug-in core are injection molded from plastic material into one piece.

[0097] Please refer to the following: Figures 29-33 The connector 100e provided in the sixth embodiment of this application has a structure similar to that of the connector 100 provided in the first embodiment, except that the specific structure of the locking mechanism 26a in the sixth embodiment is different from that in the first embodiment. Specifically, in the sixth embodiment, the locking member 260a is a locking tongue protruding from the outside of the cover 2401, the operating member 262a is rotatably connected to the connecting seat 22, and the locking mechanism 26a further includes a third elastic member 267, which is connected to the operating member 262a and the connecting seat 22. The third elastic member 267 has a third pre-elastic force that drives the operating member 262a to rotate relative to the connecting seat 22 to lock onto the locking tongue. Specifically, a protruding strip 24011 is provided on the outer peripheral surface of the cover 2401 facing away from the rotating part 2403. The locking member 260a is a locking tongue protruding from the protruding strip 24011 facing away from the cover 2401. The locking member 260a has an abutting surface 2609a facing away from the protruding strip 24011, which is inclined to the axial direction of the sealing part 2402. The locking member 260a also has a locking opening 2631a, which is located on the surface of the locking member 260a facing away from the sealing part 2402. Anti-slip strips 24013 are provided on the surface of the cover 2401 facing away from the sealing part 2402. In this embodiment, three parallel and spaced anti-slip strips 24013 are provided on the surface of the cover 2401 facing away from the sealing part 2402.

[0098] A mounting frame 226 is provided on the outer peripheral wall of the guide tube 223 away from the connecting part 224. The operating member 262a is rotatably connected to the mounting frame 226. A locking protrusion 2203 is provided at the end of the operating member 262a facing the guide tube 223. A locking member 260a can be locked to the locking protrusion 2203. A third elastic member 267 is disposed between the mounting frame 226 and the operating member 262a. The third elastic member 267 is used to drive the locking protrusion 2203 of the operating member 262a to rotate the guide tube 223. Specifically, the mounting frame 226 has a mounting space 2260. The operating member 262a and the third elastic member 267 are both accommodated in the mounting space 2260. A rotating shaft 2262 is provided at the end of the mounting frame 226 near the guide tube 223. The end of the operating member 262a near the locking protrusion 2203 is rotatably connected to the rotating shaft 2262. In this embodiment, the mounting frame 226 includes a support plate 2263, side plates 2264 connected to opposite sides of the support plate 2263, and an end plate 2265 connected to the ends of the two side plates 2264 away from the guide tube 223. The ends of the side plates 2264 away from the end plate 2265 are connected to the guide tube 223. The support plate 2263, the two side plates 2264, and the end plate 2265 form a mounting space 2260. The ends of the two side plates 2264 near the guide tube 223 are provided with a first shaft hole 2266, and the end of the operating member 262a near the locking protrusion 2203 is provided with a second rotating hole 2626. The two side plates 2264 of the mounting frame 226 are provided with stop strips 2267 near the first shaft hole 2266. The operating member 262a is provided with a stop block 2627 at one end near the second rotating hole 2626. The stop block 2627 and the bottom surface of the operating member 262a form a stop opening 2628. The bottom surface of the operating member 262a away from the stop block 2627 is provided with a third positioning post 2629. One end of the third elastic member 267 is positioned at the third positioning post 2629. The support plate 2263 is provided with a positioning hole 2268 at one end away from the guide tube 223. The other end of the third elastic member 267 is positioned at the positioning hole 2268. In other embodiments, the operating member 262a has a positioning hole at one end of its surface facing the mounting frame 226 away from the locking protrusion 2203, and one end of the third elastic member 267 is positioned in the positioning hole. The support plate 2263 has a positioning post at one end away from the guide tube 223, and the other end of the third elastic member 267 is positioned in the positioning post.

[0099] When assembling the charging interface protection device 20e, one end of the third elastic member 267 is positioned on the third positioning post 2629. The operating member 262a and the third elastic member 267 are placed in the mounting space 2260 of the mounting frame 226, so that the other end of the third elastic member 267 is positioned on the positioning hole 2268. The second rotating hole 2626 is aligned with the first shaft hole 2266. The rotating shaft 2262 is inserted into the first shaft hole 2266 and the second rotating hole 2626, so that the operating member 262a is rotatably connected to the mounting frame 226. The third elastic member 267 elastically pushes the operating member 262a until the stop bar 2267 abuts against the stop mouth 2628. The rotating part 2403 and the driving member 241 are housed in the connecting space 2245 of the connecting seat 22, so that the second shaft hole 2246 is directly opposite the first rotating hole 2409; the rotating shaft 247 is inserted into the inner cavity of the second shaft hole 2246, the first rotating hole 2409 and the rotating cylinder 2412, and the two elastic feet 2414 elastically abut against the connecting seat 22 and the rotating part 2403 respectively. The driving member 241 drives the cover 240a to rotate relative to the connecting seat 22 until the rotating part 2403 stops at the stop block 2247; the sealing ring 243 is positioned in the annular groove 2400 so that the sealing ring 243 is sealed and fitted onto the sealing part 2402.

[0100] Mounting panel 50 is fitted onto connector body 60, so that cavity 62 passes through mounting hole 52. Mounting panel 50 is stacked on fixing plate 66, and four through holes 54 are respectively aligned with four fixing holes 662. Connecting plate 221 is stacked on the surface of mounting panel 50 away from fixing plate 66, so that cavity 62 is inserted into inner cavity of guide tube 223, and four connecting holes 2212 are respectively aligned with four through holes 54. Four locking fasteners, such as screws, pass through four connecting holes 2212 and four through holes 54 and are locked into four fixing holes 662, so that charging interface protection device 20e, mounting panel 50 and connector body 60 are connected as one unit, and locking member 260 is locked to locking protrusion 2203.

[0101] like Figures 31-35 As shown, when it is necessary to open the cover 2401, the operator presses the operating member 262a from the side away from the connecting seat 22, so that the operating member 262a rotates along the rotating shaft 2262, thereby driving the locking protrusion 2203 away from the locking member 260a, until the locking protrusion 2203 disengages from the locking member 260a; the driving member 241 drives the cover 240a to rotate along the rotating shaft 247 away from the locking member 220, until the cover 240a stops at the stop block 2247, and the cover 240a opens the inner cavity 2230 of the guide tube 223, so that the plug to be inserted can pass through the inner cavity 2230 and be inserted into the insertion core 64.

[0102] When it is necessary to lock the charging interface protection device 20e, the plug to be inserted is pulled out of the connector, and the operator pushes the cover 2401 to rotate the cover 240a relative to the connector 22 toward the operating member 262a. The abutting surface 2609a of the locking member 260a slides against the locking protrusion 2203; as Figure 33 As shown, the pushing force F on the cover 2401 is decomposed into a first component force F1 and a second component force F2. The first component force F1 causes the cover 2401 to move towards the connecting seat 22, and the second component force F2 pushes the operating member 262a to rotate along the rotating shaft 2262, so as to drive the locking protrusion 2203 away from the cover 2401, and the third elastic member 267 undergoes elastic deformation. When the locking member 260a passes the locking protrusion 2203, the third elastic member 267 elastically resets to drive the operating member 262a to rotate and reset, until the locking protrusion 2203 is locked to the locking member 260a, and the stop block 2627 is positioned at the stop opening 2628.

[0103] The operating element 262a of the connector 100d of this application is disposed on the surface of the connector base 22 opposite to the connector body 60. The unlocking interface is intuitive and convenient for the operator to unlock or lock.

[0104] In other embodiments, a cavity 62 is added to the connecting seat 22 in the sixth embodiment, meaning that the connecting seat 22 and the cavity are an integral structure. Optionally, the connecting seat 22 and the cavity are injection molded from plastic material as a single unit.

[0105] In other embodiments, a cavity and a plug-in core are added to the connector 22 in the sixth embodiment, meaning that the connector 22, the cavity, and the plug-in core are integrated into one structure. Optionally, the connector 22, the cavity, and the plug-in core are injection molded from plastic material into one piece.

[0106] The embodiments of this application have been described in detail above.
