DETAILED DESCRIPTION

[0046] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] The connector 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0048] like Figure 1-Figure 8 As shown, the connector 1 according to the embodiment of the present invention includes a housing 10 , a sealing cover 30 and a connecting assembly 40 .

[0049] The shell 10 defines a docking cavity 11, which has a docking port 111 suitable for plugging and mating with the mating end 61. When the connector 1 needs to dock with the mating end 61 to transmit signals or power, the mating end 61 can be plugged and mated with the docking port 111 to connect the mating end 61 and the shell 10 together. At the same time, part of the mating end 61 extends into the docking cavity 11 from the docking port 111 to achieve docking between the mating end 61 and the components in the docking cavity 11 (such as the terminal 41 described later).

[0050] The housing 10 is connected to the sealing cover 30 through the connecting assembly 40, and the sealing cover 30 can move relative to the housing 10. The sealing cover 30 is connected to the housing 10 through the connecting assembly 40 and the sealing cover 30 can move relative to the housing 10. The sealing cover 30 has a sealing state and a storage state. When the sealing cover 30 is in the sealing state, the sealing cover 30 is sealed with the docking port 111 to close the docking port 111, so that the sealing cover 30 seals the docking cavity 11, which can prevent liquid in the environment from entering the docking cavity 11 from the docking port 111. When the sealing cover 30 is in the storage state, the sealing cover 30 is located outside the docking cavity 11 and avoids the docking port 111. At this time, the sealing cover 30 opens the docking port 111, and the mating end 61 can extend from the docking port 111 into the docking cavity 11 to achieve docking with the components in the docking cavity 11.

[0051] Specifically, when the mating end 61 does not need to be connected to the components in the docking cavity 11, the sealing cover 30 can be moved to a sealing state, and the sealing cover 30 can be used to close the docking port 111 to prevent the liquid in the environment from entering the docking cavity 11 from the docking port 111. When the mating end 61 needs to be connected to the components in the docking cavity 11, the sealing cover 30 can be moved to a storage state. At this time, the sealing cover 30 opens the docking port 111, so that the mating end 61 can extend into the docking cavity 11 from the docking port 111 to achieve the docking of the mating end 61 with the components in the docking cavity 11. At this time, the mating end 61 blocks the liquid from flowing to the components in the docking cavity 11 to a certain extent, so as to protect the components in the docking cavity 11 and reduce the possibility of the components in the docking cavity 11 contacting with the liquid.

[0052] Among them, by connecting the sealing cover 30 to the shell 10, the sealing cover 30 is always connected to the shell 10 regardless of whether the sealing cover 30 is in a sealed state or a stored state. Compared with detachably setting the sealing cover on the shell, this solution does not need to worry about the sealing cover 30 being lost due to being placed randomly, which is convenient for improving user convenience.

[0053] According to the connector 1 of the embodiment of the utility model, a sealing cover 30 is provided, and the sealing cover 30 can be used to close the docking port 111, wherein the sealing cover 30 is always connected to the housing 10 regardless of whether the sealing cover 30 is in a sealed state or a stored state, and there is no need to worry about the sealing cover 30 being lost due to being placed randomly, thereby improving the user's convenience.

[0054] In some embodiments of the present invention, Fig.12 As shown, the sealing cover 30 defines a mating groove 31. When the sealing cover 30 is in a sealed state, one end of the shell 10 corresponding to the docking port 111 is inserted into the mating groove 31, so as to enhance the tightness of the mating between the sealing cover 30 and the shell 10, so that the sealing cover 30 can fully close the docking port 111.

[0055] Specifically, one end of the shell 10 corresponding to the docking port 111 is inserted into the mating groove 31, so that the side wall of the mating groove 31 can be matched with the shell 10, thereby increasing the fitting area between the shell 10 and the sealing cover 30, thereby facilitating reducing the gap between the shell 10 and the sealing cover 30.

[0056] In addition, one end of the shell 10 corresponding to the docking port 111 is inserted into the mating groove 31 so as to form a gap with a bending portion between the shell 10 and the sealing cover 30. In this way, even if liquid flows into the gap between the shell 10 and the mating groove 31, compared with a straight gap, it is not easy for the liquid to pass through the gap with the bending portion, thereby reducing the possibility of liquid flowing to the components in the docking cavity 11 and improving the sealing performance of the sealing cover 30 to the docking port 111.

[0057] In some embodiments, the mating groove 31 is formed as an annular groove. When the shell 10 is mated with the mating groove 31, the side walls on the opposite sides of the mating groove 31 can clamp the shell 10 so that there is a certain force between the side walls of the mating groove 31 and the shell 10, and then the opposite side walls of the mating groove 31 can respectively fit the inner circumference and outer circumference of the shell 10, so as to reduce the gap between the side walls of the mating groove 31 and the shell 10.

[0058] In some optional embodiments of the present invention, one of the mating groove 31 and the shell 10 is provided with a snap-fit ​​protrusion 32, and the other is provided with a snap-fit ​​groove 12. In the sealed state, the snap-fit ​​protrusion 32 cooperates with the snap-fit ​​groove 12 to limit the relative movement of the sealing cover 30 and the shell 10. In this way, when the connector 1 is moved or a force is accidentally applied to the sealing cover 30, the mating groove 31 is not easy to disengage from the shell 10, which facilitates improving the stability of the mating between the sealing cover 30 and the docking port 111.

[0059] like Figure 8 , Fig.12 As shown, in the present embodiment, a snap-fitting protrusion 32 is provided on the groove side wall of the mating groove 31, and a snap-fitting groove 12 is provided on the outer periphery of one end of the shell 10 corresponding to the docking port 111. When the end of the shell 10 extends into the mating groove 31 and fits into place, the snap-fitting groove 12 cooperates with the snap-fitting protrusion 32 to limit the relative movement of the sealing cover 30 and the shell 10 along the front-to-back direction, thereby improving the stability of the mating between the sealing cover 30 and the docking port 111.

[0060] In some specific embodiments of the present invention, Fig.11 , Fig.12 As shown, the mating groove 31 is formed as an annular groove, and the annular groove has an inner groove wall 311 and an outer groove wall 312. The outer groove wall 312 is spaced apart on the outer side of the inner groove wall 311 in the radial direction of the annular groove. A sealing member 42 is provided on one of the inner groove wall 311 and the outer groove wall 312, and a snap-fit ​​protrusion 32 and one of the snap-fit ​​grooves 12 are provided on the other. In the sealed state, the sealing member 42 is sealed between the sealing cover 30 and the housing 10. At this time, the inner groove wall 311 can be opposite to the inner circumferential surface of the housing 10, and the outer groove wall 312 can be opposite to the outer circumferential surface of the housing 10.

[0061] Among them, the cooperation between the snap-fit ​​protrusion 32 and the snap-fit ​​groove 12 can limit the relative movement of the shell 10 and the sealing cover 30, so that the shell 10 and the matching groove 31 can be stably plugged in and matched, and a sealing member 42 is arranged in the matching groove 31 to utilize the sealing member 42 to seal the gap between the shell 10 and the side wall of the matching groove 31, thereby improving the sealing performance of the sealing cover 30 to the docking interface 111.

[0062] In addition, a sealing member 42 is provided on one of the inner groove wall 311 and the outer groove wall 312, and one of the snap-fitting protrusion 32 and the snap-fitting groove 12 is provided on the other one, that is, the sealing member 42 is located on the inner side of the shell 10, and the snap-fitting protrusion 32 and the snap-fitting groove 12 are located on the outer side of the shell 10, or, the sealing member 42 is located on the outer side of the shell 10, and the snap-fitting protrusion 32 and the snap-fitting groove 12 are located on the inner side of the shell 10; then, the cooperation between the snap-fitting protrusion 32 and the snap-fitting groove 12 has a relatively small influence on the sealing effect of the sealing member 42, and when the snap-fitting protrusion 32 cooperates with the snap-fitting groove 12, the sealing member 42 can provide a deformation amount for the end of the shell 10, so that the snap-fitting protrusion 32 can smoothly cooperate with the snap-fitting groove 12, so that the shell 10 and the matching groove 31 can be docked in place.

[0063] Specifically, a snap-fitting protrusion 32 is provided on the outer groove wall 312 of the mating groove 31. In the sealed state, the sealing member 42 is located between the inner groove wall 311 and the shell 10. When the snap-fitting protrusion 32 is mated with the outer peripheral surface of the shell 10, under the action of the snap-fitting protrusion 32, the end of the shell 10 will be deformed in the direction close to the inner groove wall 311, so that the sealing cover 30 and the shell 10 can smoothly move toward each other. When the snap-fitting protrusion 32 is mated with the snap-fitting groove 12, the end of the shell 10 tends to restore the deformation.

[0064] Among them, the seal 42 is arranged between the shell 10 and the inner groove wall 311, so that the seal 42 can provide flexible support for the shell 10, and then when the shell 10 is deformed, the shell 10 can compress the seal 42, so that the shell 10 can deform smoothly. When the shell 10 restores its deformation, the seal 42 also restores its deformation to fully seal the gap between the shell 10 and the inner groove wall 311.

[0065] In some specific embodiments of the present invention, Fig.12 As shown, the sealing member 42 is arranged on the inner groove wall 311, and the snap-in protrusion 32 is arranged on the outer groove wall 312, which facilitates the assembly of the sealing member 42 and the sealing cover 30. When the sealing cover 30 is docked with the docking port 111, the snap-in protrusion 32 of the sealing cover 30 is located on the outer side of the shell 10. In this way, when the sealing cover 30 is used to seal the docking port 111, the docking difficulty is reduced, so as to facilitate and quickly realize the docking of the sealing cover 30 and the shell 10.

[0066] In some optional embodiments of the present invention, Figure 3-Figure 6 and Fig.12As shown, the shell 10 defines a cylindrical structure, and the docking port 111 is located at one axial end of the cylindrical structure. The connecting assembly 40 includes a rotating shaft 34, and the sealing cover 30 can rotate around the rotating shaft 34 relative to the shell 10. The central axis of the rotating shaft 34 is perpendicular to the axial direction of the cylindrical structure, so that when the sealing cover 30 rotates and rotates a certain angle, the side wall of the sealing cover 30 with a larger area can be rotated to a position opposite to the docking port 111, thereby enabling the sealing cover 30 to close the docking port 111. At the same time, the sealing cover 30 can avoid the docking port 111 by rotating relative to the shell 10.

[0067] Among them, the rotating shaft 34 can move relative to the shell 10 along the axial direction of the cylindrical structure to adjust the position of the sealing cover 30 relative to the shell 10, so as to enable the sealing cover 30 to move to a position farther away from the shell 10, thereby avoiding that the shell 10 will be located on the rotation path of the sealing cover 30 when the sealing cover 30 is rotated, and avoiding that the shell 10 will interfere with the rotation of the sealing cover 30; at the same time, it is beneficial to save the space occupied by the connector 1 when the sealing cover 30 is in the storage state.

[0068] Exemplarily, the axial ends of the cylindrical structure are respectively the first end and the second end, and the docking port 111 is located at the first end. In the stored state, the sealing cover 30 is arranged on the upper side of the shell 10 and avoids the docking port 111, that is, the sealing cover does not cover the docking port 111; when the sealing cover 30 needs to be rotated, the rotating shaft 34 can be moved along the axial direction of the cylindrical structure, and the sealing cover 30 can be moved along the second end toward the first end, so that sufficient space can be reserved between the rotating shaft 34 and the first end, so that the sealing cover 30 can smoothly rotate around the central axis of the rotating shaft 34; when the sealing cover 30 is rotated to the specified position and maintained at the specified position (for example, the sealing cover 30 is perpendicular to the axial direction of the cylindrical structure), the rotating shaft 34 can be moved along the axial direction of the cylindrical structure again, and the sealing cover 3 is moved along the first end toward the second end to adjust the relative position of the sealing cover 30 and the shell 10, so that the sealing cover 30 can seal the docking port 111, and at this time the sealing cover 30 is in a sealed state.

[0069] In some specific embodiments of the present utility model, the rotating shaft 34 is arranged on the outer peripheral side of the housing 10 and is slidably matched with the peripheral wall of the housing 10. When the sealing cover 30 is in the storage state, the sealing cover 30 is arranged on the outer peripheral side of the housing 10 and the peripheral wall of the housing 10 is covered on the open side of the matching groove 31, so as to use the outer peripheral side of the housing 10 to seal the open side of the matching groove 31, so as to prevent dust and other substances in the environment from entering the matching groove 31. It can be understood that when the sealing member 42 is in the matching groove 31, in the sealing state, the sealing member 42 is sealed between the sealing cover 30 and the housing 10, and when the sealing cover 30 is in the storage state, the peripheral wall of the housing 10 is covered on the open side of the matching groove 31 to seal the matching groove 31, so as to prevent dust and other pollutants from contaminating the sealing member 42 in the matching groove 31.

[0070] In some embodiments, the axial direction of the cylindrical structure extends in the front-to-back direction (it should be understood here that the above direction limitation is only for the convenience of describing the drawings and will not limit the actual setting position and direction of the connector 1), the docking port 111 is located at the front end of the housing 10, the sealing cover 30 is arranged above the housing 10, the central axis of the rotating shaft 34 extends in the left-right direction, and the rotating shaft 34 can move in the front-to-back direction relative to the housing 10. When the sealing cover 30 is in the storage state, the matching groove 31 is arranged on the lower end surface of the sealing cover 30, so that the peripheral wall cover of the housing 10 is arranged on the open side of the matching groove 31, and in the front-to-back direction, the rotating shaft 34 is located at the rear end of the sealing cover 30.

[0071] When the sealing cover 30 moves from the storage state to the sealing state, the rotating shaft 34 is first moved forward, and then the sealing cover 30 is rotated counterclockwise around the rotating shaft 34 at its rear end to extend in the vertical direction, and then the rotating shaft 34 is moved backward, so that the matching groove 31 is plugged and matched with the end of the housing 10 corresponding to the docking port 111, and the sealing cover 30 is in the sealing state. When the sealing cover 30 moves from the sealing state to the storage state, the rotating shaft 34 is first moved forward to disengage the housing 10 from the matching groove 31, and then the sealing cover 30 is rotated clockwise around the rotating shaft 34 at its rear end to extend in the horizontal direction, and then the rotating shaft 34 is moved backward to store the sealing cover 30 directly above the housing 10, so that the upper surface of the housing 10 can close the open side of the matching groove 31.

[0072] Of course, the sealing cover 30 can also be arranged below or on the left and right sides of the shell 10. When the sealing cover 30 is arranged above or below the shell 10, the central axis of the rotating shaft 34 extends in the left-right direction. When the sealing cover 30 is arranged on the left or right side of the shell 10, the central axis of the rotating shaft 34 extends in the up-down direction. In the embodiment where the sealing cover 30 is arranged below or on the left and right sides of the shell 10, the movement mode of the sealing cover 30 is the same as that of the above-mentioned embodiment, which will not be repeated here.

[0073] In other specific embodiments of the present invention, Figure 8 and Fig.12As shown, the connection assembly 40 also includes a sliding cover 20, which is located outside the docking cavity 11 and is slidably disposed on the housing 10 along the axial direction of the cylindrical structure. The rotating shaft 34 is fixed on the sliding cover 20. When the sliding cover 20 slides along the axial direction of the cylindrical structure, the sliding cover 20 can drive the sealing cover 30 to move along the axial direction of the cylindrical structure. When the sealing cover 30 is in the storage state, the sealing cover 30 is disposed between the housing 10 and the sliding cover 20, and the sliding cover 20 covers the open side of the matching groove 31 to close the open side of the matching groove 31 to prevent dust and other substances in the environment from entering the matching groove 31. In this way, when the end of the housing 10 corresponding to the docking port 111 is plugged and matched with the matching groove 31, dust and other substances can be prevented from affecting the matching between the housing 10 and the matching groove 31, and dust can be prevented from polluting the environment in the docking cavity 11. It can be understood that when the seal 42 is in the mating groove 31, in the sealed state, the seal 42 is sealed between the sealing cover 30 and the housing 10. When the sealing cover 30 is in the storage state, the sliding cover 20 is covered on the open side of the mating groove 31 to close the mating groove 31 to prevent dust and other pollutants from contaminating the seal 42 in the mating groove 31.

[0074] like Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, the axial direction of the cylindrical structure extends in the front-to-back direction, the docking port 111 is located at the front end of the housing 10, the sealing cover 30 and the sliding cover 20 are arranged above the housing 10, the central axis of the rotating shaft 34 extends in the left-right direction, and the sliding cover 20 can move in the front-to-back direction relative to the housing 10. When the sealing cover 30 is in the storage state, the sliding cover 20 closes the open side of the matching groove 31, wherein, when the sealing cover 30 is in the storage state, the matching groove 31 is located at the upper end surface of the sealing cover 30, and in the front-to-back direction, the rotating shaft 34 is located at the front end of the sealing cover 30.

[0075] When the sealing cover 30 moves from the storage state to the sealing state, the rotating shaft 34 is first moved forward, and then the sealing cover 30 is rotated clockwise around the rotating shaft 34 at its front end until it extends in the vertical direction, and then the rotating shaft 34 is moved backward, so that the matching groove 31 is plugged and matched with the end of the housing 10 corresponding to the docking port 111, and the sealing cover 30 is in the sealing state. When the sealing cover 30 moves from the sealing state to the storage state, the rotating shaft 34 is first moved forward, and then the sealing cover 30 is rotated counterclockwise around the rotating shaft 34 at its front end until it extends in the horizontal direction, and then the rotating shaft 34 is moved backward, the sealing cover 30 is stored directly above the housing 10, and the open mouth of the matching groove 31 is closed by the sliding cover 20.

[0076] Of course, the sealing cover 30 and the sliding cover 20 can also be arranged below or on the left and right sides of the shell 10. When the sealing cover 30 and the sliding cover 20 are arranged above or below the shell 10, the central axis of the rotating shaft 34 extends in the left-right direction. When the sealing cover 30 and the sliding cover 20 are arranged on the left or right side of the shell 10, the central axis of the rotating shaft 34 extends in the up-down direction. In the embodiment in which the sealing cover 30 and the sliding cover 20 are arranged below or on the left and right sides of the shell 10, the movement mode of the sealing cover 30 is the same as that of the above-mentioned embodiment, which will not be repeated here.

[0077] In some other specific embodiments of the present invention, Fig.15 As shown, the connection assembly 40 also includes a sliding cover 20, which is located outside the docking cavity 11 and is slidably disposed on the housing 10 along the axial direction of the cylindrical structure. The rotating shaft 34 is fixed on the sliding cover 20. When the sliding cover 20 slides along the axial direction of the cylindrical structure, the sliding cover 20 can drive the sealing cover 30 to move along the axial direction of the cylindrical structure. When the sealing cover 30 is in the storage state, the peripheral wall cover of the housing 10 is disposed on the open side of the matching groove 31 to close the open side of the matching groove 31 to prevent dust and other substances in the environment from entering the matching groove 31. In this way, when the end of the housing 10 corresponding to the docking port 111 is plugged and matched with the matching groove 31, dust and other substances can be prevented from affecting the matching of the housing 10 and the matching groove 31, and dust can be prevented from polluting the environment in the docking cavity 11. It can be understood that when the seal 42 is in the mating groove 31, in the sealed state, the seal 42 is sealed between the sealing cover 30 and the shell 10. When the sealing cover 30 is in the storage state, the peripheral wall cover of the shell 10 is arranged on the open side of the mating groove 31 to close the mating groove 31 to prevent dust and other pollutants from contaminating the seal 42 in the mating groove 31.

[0078] In some embodiments, Fig.15 As shown, the axial direction of the cylindrical structure extends in the front-to-back direction (it should be understood here that the above direction limitation is only for the convenience of describing the drawings and will not limit the actual setting position and direction of the connector 1), the docking port 111 is located at the front end of the housing 10, the sealing cover 30 and the sliding cover 20 are arranged above the housing 10, the sealing cover 30 is arranged between the housing 10 and the sliding cover 20, the central axis of the rotating shaft 34 extends in the left-right direction, and the rotating shaft 34 can move in the front-to-back direction relative to the housing 10. When the sealing cover 30 is in the storage state, the matching groove 31 is arranged on the lower end surface of the sealing cover 30, and the rotating shaft 34 is located at the rear end of the sealing cover 30 in the front-to-back direction.

[0079] When the sealing cover 30 moves from the storage state to the sealing state, the sliding cover 20 is first moved forward and drives the sealing cover 30 to move forward, and then the sealing cover 30 is rotated counterclockwise around the rotation axis 34 at its rear end to extend in the vertical direction, and then the sliding cover 20 is moved backward and drives the rotation axis 34 to move backward, so that the matching groove 31 is plugged and matched with the end of the housing 10 corresponding to the docking port 111, and the sealing cover 30 moves to the sealing state. When the sealing cover 30 moves from the sealing state to the storage state, the sliding cover 20 is first moved forward to disengage the housing 10 from the matching groove 31, and then the sealing cover 30 is rotated clockwise around the rotation axis 34 at its rear end to extend in the horizontal direction, and then the sliding cover 20 is moved backward to store the sealing cover 30 directly above the housing 10, so that the upper end surface of the housing 10 can close the open mouth of the matching groove 31.

[0080] Of course, the sealing cover 30 and the sliding cover 20 can also be arranged below or on the left and right sides of the shell 10. When the sealing cover 30 and the sliding cover 20 are arranged above or below the shell 10, the central axis of the rotating shaft 34 extends in the left-right direction. When the sealing cover 30 and the sliding cover 20 are arranged on the left or right side of the shell 10, the central axis of the rotating shaft 34 extends in the up-down direction. In the embodiment in which the sealing cover 30 and the sliding cover 20 are arranged below or on the left and right sides of the shell 10, the movement mode of the sealing cover 30 is the same as that of the above-mentioned embodiment, which will not be repeated here.

[0081] In some other embodiments of the present invention, the sealing cover 30 can rotate around the rotating shaft 34 relative to the housing 10, the central axis of the rotating shaft 34 is perpendicular to the axial direction of the cylindrical structure, and the rotating shaft 34 can move relative to the housing 10 along the extension direction of its central axis.

[0082] For example, the axial direction of the cylindrical structure extends in the front-to-back direction, the docking port 111 is located at the front end of the housing 10, the sealing cover 30 is arranged above the housing 10, the central axis of the rotating shaft 34 extends in the left-right direction, and the rotating shaft 34 can move in the left-right direction relative to the housing 10. When the sealing cover 30 is in a sealed state, the sealing cover 30 extends in the vertical direction, and when the sealing cover 30 is in a stored state, the sealing cover 30 extends in the horizontal direction.

[0083] When the sealing cover 30 moves from the storage state to the sealing state, the rotating shaft 34 is first moved to the right, and then the sealing cover 30 is rotated 90° or more than 90°, and then the rotating shaft 34 is moved to the left. At this time, the sealing cover 30 can be rotated again to fine-tune the position of the sealing cover 30, so that the housing 10 and the matching groove 31 are plugged and matched, so that the sealing cover 30 can close the docking port 111. When the sealing cover 30 moves from the sealing state to the storage state, the rotating shaft 34 is first rotated by a certain angle to disengage the housing 10 from the matching groove 31, and then the sealing cover 30 is moved to the right, and then the sealing cover 30 is rotated to extend in the horizontal direction, and then the rotating shaft 34 is moved to the left to store the sealing cover 30 directly above the housing 10.

[0084] Of course, the sealing cover 30 can also be arranged below or on the left and right sides of the shell 10. When the sealing cover 30 is arranged above or below the shell 10, the central axis of the rotating shaft 34 extends in the left-right direction, and the rotating shaft 34 can move in the left-right direction relative to the shell 10. When the sealing cover 30 is arranged on the left or right side of the shell 10, the central axis of the rotating shaft 34 extends in the up-down direction, and the rotating shaft 34 can move in the up-down direction relative to the shell 10. In the embodiment where the sealing cover 30 is arranged below or on the left and right sides of the shell 10, the movement mode of the sealing cover 30 is the same as that of the above-mentioned embodiment, which will not be repeated here.

[0085] In some specific embodiments of the present invention, Fig.10 As shown, the connector 1 also includes an elastic member 43, which is sleeved on the rotating shaft 34. The elastic member 43 is used to provide an elastic force for the sealing cover 30 to rotate toward a storage position corresponding to the storage state, so that when the tension or other force acting on the sealing cover 30 disappears, the sealing cover 30 can automatically rotate to the storage position, thereby reducing the user's operation.

[0086] like Figure 5 , Figure 6 and Figure 8 As shown, in the present embodiment, when the sealing cover 30 is in the storage position, the sealing cover 30 extends in the horizontal direction, and when the sealing cover 30 is in the sealing position, the sealing cover 30 extends in the vertical direction. Specifically, when the sealing cover 30 rotates from the sealing position to the storage position, the end of the sealing cover 30 away from the rotation axis 34 thereof rotates toward the direction close to the docking port 111. If the user manually drives the sealing cover 30 to rotate to the storage position, the user's hand is likely to interfere with the shell 10, which is not conducive to the user's operation. Therefore, the elastic member 43 is used to automatically drive the sealing cover 30 to rotate to the storage position, so as to reduce the user's operation and improve the user's experience.

[0087] like Fig.11As shown, in the present embodiment, the two ends of the length of the elastic member 43 are respectively the third end 431 and the fourth end 432, the third end 431 of the elastic member 43 is arranged against the end of the sliding cover 20, when the elastic member 43 is in the storage position, the fourth end 432 of the elastic member 43 is arranged against the sealing cover 30, when the user operates the sealing cover 30 to rotate, the sealing cover 30 drives the fourth end 432 of the elastic member 43 to rotate toward the direction close to the sliding cover 20, and then applies torque to the elastic member 43, when the user releases the elastic member 43, the elastic member 43 has a driving force for the sealing cover 30 to rotate toward the storage position.

[0088] In some examples, such as Fig.11 As shown, the sealing cover 30 is provided with a first avoidance groove 361 and a second avoidance groove 362, the first avoidance groove 361 is used to avoid the third end 431 of the elastic member 43, and the second avoidance groove 362 is used to avoid the fourth end 432 of the elastic member 43. Specifically, no matter the sealing cover 30 is in the storage position or the sealing position, the third end 431 of the elastic member 43 always leans against the sliding cover 20, and when the elastic member 43 rotates to the sealing position, the sealing cover 30 rotates relative to the sliding cover 20, and the third end 431 of the elastic member 43 is located in the second avoidance groove 362, so as to avoid the third end 431 of the elastic member 43 from interfering with the sealing cover 30. When the sealing cover 30 is in the storage position, the fourth end 432 of the elastic member 43 stops at the bottom wall of the second avoidance groove 362. When the sealing cover 30 rotates toward the sealing state, the sealing cover 30 drives the fourth end 432 of the elastic member 43 to rotate toward the direction of the sliding cover 20 until the fourth end 432 of the elastic member 43 stops and cooperates with the sliding cover 20.

[0089] In some optional embodiments of the present invention, Fig.12 As shown, a seal 42 is provided in the mating groove 31. In the sealed state, the seal 42 is sealed between the sealing cover 30 and the housing 10 to seal the gap between the sealing cover 30 and the housing 10, thereby preventing dust or liquid from entering the sealed cavity from the gap between the sealing cover 30 and the housing 10, preventing dust or liquid from contaminating the docking cavity 11 or causing damage to the components in the docking cavity 11.

[0090] In some embodiments, the mating groove 31 is formed as an annular groove having an inner groove wall 311 and an outer groove wall 312. The seal 42 is disposed between the shell 10 and the inner groove wall 311 so that the seal 42 can provide flexible support for the shell 10, so that when the shell 10 is deformed, the shell 10 can compress the seal 42 so that the shell 10 can deform smoothly. When the shell 10 recovers its deformation, the seal 42 also recovers its deformation to fully seal the gap between the shell 10 and the inner groove wall 311.

[0091] In some optional embodiments of the present invention, the two axial ends of the cylindrical structure are respectively the first end and the second end, the docking port 111 is located at the first end, and the rotating shaft 34 has a first position, a second position and a third position.

[0092] like Figure 4 , Figure 5 As shown, in the first position, in the axial direction of the cylindrical structure, the rotating shaft 34 is spaced apart on the side of the first end away from the second end, so that the sealing cover 30 can rotate around the rotating shaft 34. When the rotating shaft 34 is in the first position, space can be reserved for the rotation of the sealing cover 30 to adjust the posture of the sealing cover 30. Specifically, when the sealing cover 30 needs to be rotated, the rotating shaft 34 needs to be moved to the first position first.

[0093] like Figure 1 and Figure 3 As shown, in the second position, in the axial direction of the cylindrical structure, the rotating shaft 34 is arranged at the first end of the shell 10 to limit the sealing cover 30 in a sealed state. After the sealing cover 30 is rotated at the first position to adjust the posture of the sealing cover 30, the rotating shaft 34 is slid to the second position to switch the sealing cover 30 to the sealed state.

[0094] like Figure 8 , Fig.14 and Fig.15 As shown, in the third position, in the axial direction of the cylindrical structure, the rotating shaft 34 is spaced apart at a side of the first end of the shell 10 away from the second end, or the rotating shaft 34 is spaced apart between the first end and the second end, or the rotating shaft 34 is arranged at the first end, so that the sealing cover 30 is limited in the storage state. After the sealing cover 30 is rotated at the first position to adjust the position of the sealing cover 30, the rotating shaft 34 is slid to the third position to limit the position of the sealing cover 30, so that the sealing cover 30 is in the storage state.

[0095] Exemplarily, in the first position, the distance between the rotating shaft 34 and the second end in the axial direction of the cylindrical structure is x1, in the second position, the distance between the rotating shaft 34 and the second end in the axial direction of the cylindrical structure is x2, and in the third position, the distance between the rotating shaft 34 and the second end in the axial direction of the cylindrical structure is x3, x3≤x1, x2<x1, x2 and x3 can be equal or unequal, for example, x2>x3 or x2<x3.

[0096] like Figure 1 , Figure 8As shown, in some embodiments, the sealing cover 30 has a first posture that is the same as the posture when it is in a sealed state, and also has a second posture that is the same as the posture when it is in a stored state. In the first posture, the sealing cover 30 extends in a vertical direction, and in the second posture, the sealing cover 30 extends in a horizontal direction. When the rotating shaft 34 is in the first position, the rotating shaft 34 is spaced from the first end of the shell 10. At this time, the sealing cover 30 can be rotated so that the sealing cover 30 can be rotated between the stored position and the sealing position.

[0097] After the posture of the sealing cover 30 is adjusted to the first posture, the rotating shaft 34 is slid backward. When the rotating shaft 34 is in the second position, the sealing cover 30 closes the docking port 111. At this time, the sealing cover 30 is in a sealed state.

[0098] After the posture of the sealing cover 30 is adjusted to the second posture, the rotating shaft 34 is slid backward, and when the rotating shaft 34 is in the third position, the sealing cover 30 is in the stored state.

[0099] In some optional embodiments of the present invention, the axial ends of the cylindrical structure are respectively a first end and a second end, and the docking port 111 is located at the first end; the connecting assembly 40 also includes a sliding cover 20, which is located outside the docking cavity 11 and is slidably arranged on the shell 10 along the axial direction of the cylindrical structure, and the rotating shaft 34 is fixed on the sliding cover 20. A first limiting assembly is provided between the sliding cover 20 and the shell 10, and the first limiting assembly is used to limit the sliding cover 20 from being separated from the shell 10 from the first end. A second limiting assembly is provided between the sealing cover 30 and the shell 10, and the second limiting assembly is used to limit the sliding cover 20 from being separated from the shell 10 from the second end, so as to avoid the sealing cover 30 from being separated from the shell 10 when the sliding cover 20 moves relative to the shell 10, thereby improving the matching reliability of the sliding cover 20 and the shell 10.

[0100] In some specific embodiments of the present utility model, the sliding cover 20 has a first sliding member, and the housing 10 has a second sliding member. The first sliding member and the second sliding member slide and cooperate along the axial direction of the cylindrical structure, thereby realizing the sliding of the sliding cover 20 along the axial direction of the cylindrical structure. When the sliding cover 20 slides, the rotating shaft 34 of the sliding cover 20 can slide along the axial direction of the cylindrical structure, so that the rotating shaft 34 slides and cooperates with the peripheral wall of the housing 10. The first limiting assembly between the sliding cover 20 and the housing 10 can be provided on the first sliding member and the second sliding member. Of course, the first limiting assembly can also be spaced apart from the first sliding member and the second sliding member.

[0101] In some embodiments, Figure 5 , Figure 6 and Fig.10As shown, the first limit assembly includes a first stop protrusion 24 and a second stop protrusion 14. The first stop protrusion 24 is arranged at an end of the first sliding member away from the rotating shaft 34 and the first stop protrusion 24 is slidably matched with the second sliding member. The second stop protrusion 14 is arranged at an end of the second sliding member close to the first end and the second stop protrusion 14 is slidably matched with the first sliding member. The first stop protrusion 24 is suitable for stopping with the second stop protrusion 14 along the axial direction of the cylindrical structure to limit the sliding cover 20 from being separated from the shell 10.

[0102] like Figure 5 As shown, in some examples, the first sliding member is a slide groove 23, the second sliding member is a slide rail 13, the slide groove 23 and the slide rail 13 both extend in the front-rear direction, the first stop protrusion 24 is provided at the rear end of the slide groove 23, and the second stop protrusion 14 is provided at the front end of the slide rail 13, when the slide cover 20 moves forward relative to the housing 10, the first stop protrusion 24 and the second stop protrusion 14 stop against each other, so as to limit the range of the slide cover 20 that can slide forward, and prevent the slide rail 13 from being disengaged from the slide cover 20. Of course, in other examples, the first sliding member is the slide rail 13, and the second sliding member is the slide groove 23.

[0103] In some examples, such as Figure 5 , Fig. 9 and Fig.10 As shown, the size of the front end opening of the slide groove 23 is larger than the size of the second stop protrusion 14. When the slide cover 20 and the shell 10 need to be separated, the slide cover 20 can be slid backward to make the second stop protrusion 14 slide out of the slide rail 13 from the front end of the slide groove 23, thereby realizing the separation of the shell 10 and the slide cover 20. Correspondingly, the second stop protrusion 14 can also enter the slide rail 13 from the front end opening of the slide groove 23 to realize the cooperation between the slide groove 23 and the slide rail 13, thereby slidably installing the slide cover 20 on the shell 10.

[0104] In some specific embodiments of the present invention, Figure 8 , Fig.10 As shown, the second limiting assembly includes a limiting groove 35 and a limiting elastic member 15. The limiting groove 35 is formed on one side of the sealing cover 30 that is away from the open side of the matching groove 31, so as to separate the limiting groove 35 from the matching groove 31 to avoid interference between the two.

[0105] The limiting elastic member 15 is cantilevered on the shell 10 and extends obliquely toward one end where the docking port 111 is located. When the sealing cover 30 is in the storage position and the rotating shaft 34 slides to the third position, the limiting elastic member 15 cooperates with the limiting groove 35 to limit the sealing cover 30 in the storage state so that the sliding cover 20 will not continue to move.

[0106] Specifically, the limiting elastic member 15 is cantilevered on the housing 10 and extends obliquely toward one end where the docking port 111 is located, so that the limiting elastic member 15 can be elastically deformed and can smoothly match with the limiting groove 35, wherein when the sliding cover 20 moves in a direction away from the first end, the cantilever end of the limiting elastic member 15 first extends into the limiting groove 35, and after the sliding cover 20 slides into place, the cantilever end of the limiting elastic member 15 and the inner side wall of the limiting groove 35 are abutted and matched to limit the movement of the sealing cover 30, thereby limiting the sealing cover 30 in the storage state. When the sliding cover 20 moves in a direction close to the first end, the cantilever end of the limiting elastic member 15 can be deformed after receiving the force, so that the limiting elastic member 15 can be disengaged from the limiting groove 35, thereby allowing the sliding cover 20 to smoothly move in a direction close to the docking port 111.

[0107] In some embodiments, Figure 4 , Figure 8 As shown, the limiting elastic member 15 is arranged near the rear end of the shell 10, and the limiting elastic member 15 extends obliquely upward from the back to the front. The limiting groove 35 is arranged on the sealing cover 30. When the sealing cover 30 is in the storage position, the limiting groove 35 is located on the lower surface of the sealing cover 30. When the sliding cover 20 slides backward relative to the shell 10, the slide rail 13 may be disengaged from the slide groove 23, so that the limiting elastic member 15 cooperates with the limiting groove 35 to limit the sliding range of the sliding cover 20 backward, thereby preventing the slide rail 13 from being disengaged from the slide groove 23.

[0108] When the slide cover 20 moves backward, the front end of the limiting elastic member 15 will first extend into the limiting groove 35 until it stops against the front side wall of the limiting groove 35, and the slide cover 20 will not move backward any further. When the slide cover 20 moves forward, the front end of the limiting elastic member 15 is deformed downward after receiving pressure, and the front end of the limiting elastic member 15 can move out of the limiting groove 35, so that the limiting elastic member 15 and the limiting groove 35 are disengaged, so that the slide cover 20 can move forward smoothly.

[0109] In some specific embodiments of the present invention, Figure 6 , Fig.10 As shown, the rotating shaft 34 extends in the left-right direction, and mounting holes are provided on the left and right side walls of the sliding cover 20. When the sealing cover 30 is rotatably mounted on the sliding cover 20, the rotating shaft 34 is first passed through the mounting hole on one side wall of the sliding cover 20, and then the sealing cover 30 and the elastic member 43 are passed through the rotating shaft 34, the elastic member 43 is clamped between the left and right ends of the sealing cover 30, and then the other end of the rotating shaft 34 is passed through the mounting hole on the other side of the sliding cover 20.

[0110] The sealing cover 30 is rotatably mounted on the sliding cover 20 via the rotating shaft 34, so as to better connect the sliding cover 20 and the sealing cover 30, and enable the sealing cover 30 to stably rotate between the storage position and the sealing position.

[0111] In some examples, both ends of the rotating shaft 34 are provided with a stop portion, and the size of the stop portion is larger than the size of the mounting through hole, so as to limit the position of the left and right ends of the rotating shaft 34, and then the rotating shaft 34 is rotatably provided on the sliding cover 20, wherein the rotating shaft 34 is detachably connected to one of the two stop portions, and the other is integrally formed; or, the rotating shaft 34 is detachably connected to both stop portions.

[0112] For example, the rotating shaft 34 is a bolt, one of the stop parts is a nut on the bolt, and the other stop part is a nut.

[0113] In some embodiments of the present invention, Figure 2 As shown, a handle portion 33 is provided at one end of the sealing cover 30 away from the rotating shaft 34 thereof, and the user can pull the handle portion 33 to drive the sealing cover 30 to rotate from the storage position to the sealing position, thereby improving the convenience of user operation.

[0114] The connector assembly 60 according to the embodiment of the present invention is described below. The connector assembly 60 according to the embodiment of the present invention comprises the connector 1 according to the above embodiment of the present invention and a mating end 61, the mating end 61 is detachably docked with the docking port 111 to achieve connection or separation between the mating end 61 and the housing 10.

[0115] In some embodiments, the docking cavity 11 is provided with a terminal 41, and the mating terminal 61 can extend into the docking cavity 11 from the docking port 111 to achieve docking with the terminal 41, wherein, in the sealed state, the sealing cover 30 is sealed with the docking port 111 to close the docking port 111, so as to prevent liquid in the environment from entering the docking cavity 11 from the docking port 111, so as to fully protect the terminal 41. In the storage state, the sealing cover 30 is located outside the docking cavity 11 and avoids the docking port 111. At this time, the sealing cover 30 opens the docking port 111, so that the mating terminal 61 can extend into the docking cavity 11 to achieve docking with the terminal 41.

[0116] According to the connector assembly 60 of the embodiment of the utility model, by utilizing the connector 1 according to the above-mentioned embodiment of the utility model, no matter the sealing cover 30 is in a sealing state or a storage state, the sealing cover 30 is always connected to the shell 10, and there is no need to worry about the sealing cover 30 being lost due to being placed randomly, so as to ensure the integrity of the various components of the connector assembly 60.

[0117] The following describes a vehicle according to an embodiment of the present invention, which includes a connector assembly 60 according to the above embodiment of the present invention.
