In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] In this embodiment, if Figures 1 to 4 As shown, the connector includes: a socket 1, a waterproof cylinder 3, a plug 2 and a connector. The waterproof cylinder 3 is rotatably arranged on the socket 1. The plug 2 is inserted into the waterproof cylinder 3 to be electrically connected to the socket 1. The connector is connected to the plug 2, and the connector has a locked state in which it is fixedly connected to the waterproof cylinder 3 and an unlocked state in which it is separated from the waterproof cylinder 3.

[0029] In this way, the plug 2 is inserted into the waterproof cylinder 3, so that the plug 2 can be electrically connected to the socket 1, and because the waterproof cylinder 3 can rotate relative to the socket 1, the plug 2 inserted into the waterproof cylinder 3 can rotate with the waterproof cylinder 3 relative to the socket 1, so that the angle of the plug 2 when electrically connected to the socket 1 is adjustable, thereby facilitating the adjustment of the angle of the plug, so that the connector can be used in complex or narrow environments, facilitating wiring operations, and also reducing excessive stretching and bending of the connection line connected to the plug, thereby reducing the problem of easy damage to the connection line connected to the plug. In addition, the setting of the connector makes the connection between the plug 2 and the waterproof cylinder 3 more convenient and reliable, so that the electrical connection between the plug 2 and the socket 1 is more stable. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the connection line connected to the plug is easily damaged when the wiring direction of the plug needs to be fine-tuned.

[0030] like Figures 1 to 6 As shown, the connector includes a first curved plate 6 and a second curved plate, and the first curved plate 6 and the second curved plate are both movably arranged on the plug 2, and the opening of the first curved plate 6 is arranged opposite to the opening of the second curved plate. When the first curved plate 6 and the second curved plate are close to each other, the connector is in a locked state, and the waterproof cylinder 3 is restricted between the first curved plate 6 and the second curved plate. When the first curved plate 6 and the second curved plate are away from each other, the connector is in an unlocked state. Through the movable design of the first curved plate 6 and the second curved plate, the conversion of the connector between the locked and unlocked states can be realized. When the first curved plate 6 and the second curved plate are close to each other, they are tightly surrounded by the outer side of the waterproof cylinder 3 and are fixedly connected to the waterproof cylinder 3, forming a firm locked state, preventing the plug 2 from coming out of the waterproof cylinder 3, so that the connection between the plug 2 and the socket 1 is more reliable. In the unlocked state, the first curved plate 6 and the second curved plate are away from each other, which is convenient for the insertion or extraction of the plug 2, simplifying the process of fixed connection or disconnection between the plug 2 and the socket 1.

[0031] like Figures 1 to 6As shown, the connector also includes a mounting plate 4 fixedly arranged on the plug 2, a mounting box 5 arranged on the mounting plate 4, a first connecting plate 11 fixedly connected to the first arc plate 6, and a second connecting plate fixedly connected to the second arc plate. The mounting plate 4 extends toward the socket 1 and is located on one side of the waterproof cylinder 3. The first connecting plate 11 and the second connecting plate can be movably arranged in the mounting box 5 and guided by the mounting box 5. The arrangement of the mounting plate 4 and the mounting box 5 provides a stable platform for the movable arrangement of the first arc plate 6 and the second arc plate. The design of the first connecting plate 11 and the second connecting plate guiding and cooperating with the mounting box 5 ensures the smoothness of the first arc plate 6 and the second arc plate during movement. At the same time, the arrangement of the guiding long hole 12 allows the first connecting plate 11 and the second connecting plate to move radially along the waterproof cylinder 3 to achieve the switching between the locked and unlocked states, thereby improving the structural stability and operational convenience of the connector.

[0032] like Figures 1 to 6 As shown, the installation box 5 is provided with a guide long hole 12 extending along the radial direction of the waterproof cylinder 3, and the first connecting plate 11 and the second connecting plate both pass through the guide long hole 12. The side wall of the first connecting plate 11 is guided and matched with the hole wall of the guide long hole 12, and the side wall of the second connecting plate is guided and matched with the hole wall of the guide long hole 12. The guide long hole 12 is guided and matched with the hole wall of the first connecting plate 11 and the second connecting plate, which not only limits the moving path of the first connecting plate 11 and the second connecting plate, but also ensures the accuracy and reliability of the moving process, avoids the connection problem caused by position deviation when switching between the locked and unlocked states, and further improves the stability and safety of the connector.

[0033] like Figures 1 to 6 As shown, the connector also includes a screw 14 rotatably disposed in the mounting box 5, the screw 14 having a first external thread section and a second external thread section with a rotation direction opposite to that of the first external thread section, the first connecting plate 11 is provided with a first threaded hole capable of threading with the first external thread section, the second connecting plate is provided with a second threaded hole capable of threading with the second external thread section, and the screw 14 is rotated to make the first connecting plate 11 and the second connecting plate approach or move away from each other. The bidirectional thread design of the screw 14 can simultaneously drive the first connecting plate 11 and the second connecting plate to move toward or away from each other by rotating the screw, which not only simplifies the operation steps, but also ensures a quick locking or unlocking process, thereby improving the operating efficiency of the connector and the reliability of the connection effect.

[0034] like Figures 1 to 6As shown, the installation box 5 is provided with a through hole and a flexible ring 13 arranged at the through hole, one end of the screw 14 passes through the through hole and the flexible ring 13 and extends out of the installation box 5, the screw 14 contacts and cooperates with the flexible ring 13, and when the screw 14 rotates, there is friction between the screw 14 and the flexible ring 13. One end of the screw 14 extends out of the installation box 5, and the connector also includes a knob 7 arranged on the end of the screw 14 extending out of the installation box 5. The setting of the flexible ring 13 increases the friction between the screw 14 and the installation box 5, so that the screw 14 can maintain a certain fixed state after stopping rotation, avoiding accidental changes in the unlocking state due to slight external force, and enhancing the stability and safety of the connector in the locked state. At the same time, the setting of the knob 7 simplifies the rotation operation of the screw 14, allowing users to easily lock and unlock, thereby improving the user experience.

[0035] In this embodiment, the flexible ring 13 is made of polymer material.

[0036] In other embodiments, the installation box 5 is provided with a through hole and a flexible ring 13 disposed at the through hole, one end of the screw rod 14 passes through the through hole and the flexible ring 13 and extends out of the installation box 5, the screw rod 14 contacts and cooperates with the flexible ring 13, and when the screw rod 14 rotates, there is friction between the screw rod 14 and the flexible ring 13. Alternatively, one end of the screw rod 14 extends out of the installation box 5, and the connector further includes a knob 7 disposed on the end of the screw rod 14 extending out of the installation box 5.

[0037] like Figures 1 to 6 As shown, the waterproof cylinder 3 includes a first cylinder body fixedly connected to the socket 1 and a second cylinder body rotatably connected to the first cylinder body, the second cylinder body is located at the end of the first cylinder body away from the socket 1, and the diameter of the second cylinder body is larger than the diameter of the first cylinder body, so as to form a stop plane on the surface of the second cylinder body facing the first cylinder body; when the connector is in a locked state, the stop plane cooperates with the first arc plate 6 stop, and the stop plane cooperates with the second arc plate stop. The difference in diameters between the first cylinder body and the second cylinder body of the waterproof cylinder 3 forms a stop plane. When the connector is in a locked state, the stop plane is in close contact with the first arc plate 6 and the second arc plate, and the stop plane can prevent the first arc plate 6 and the second arc plate from falling off from the end of the first cylinder body toward the second cylinder body, forming a double stop mechanism, which greatly improves the stability and safety of the connector when subjected to external force impact or vibration, and ensures the continuity and reliability of the electrical connection.

[0038] In this embodiment, the second cylinder is rotatably connected to the first cylinder through a bearing, and the bearing is arranged at the nesting position of the second cylinder and the first cylinder. The inner ring of the bearing is fixed to the outer wall of the first cylinder, and the outer ring of the bearing cooperates with the inner wall of the second cylinder, allowing the second cylinder to rotate freely relative to the first cylinder. The design of this bearing ensures that the second cylinder will not cause wear to the first cylinder when rotating, and also ensures the smoothness and stability of the rotation. In order to ensure the waterproof performance of the connector when the second cylinder rotates, a dynamic sealing structure is adopted. Specifically, a sealing ring is arranged at the connection between the second cylinder and the first cylinder, and the sealing ring is made of a highly elastic and water-resistant material, such as silicone rubber. The inner ring of the sealing ring is close to the outer wall of the first cylinder, and the outer ring is close to the inner wall of the second cylinder. Even when the second cylinder rotates relative to the first cylinder, it can always maintain close contact, thereby effectively preventing water and moisture from invading from the gap of the connector. The shape of the sealing ring is designed to be a lip seal or an O-ring seal to provide better contact and sealing effects. The lip seal contacts the outer wall of the first cylinder through the lip to form a multiple seal. The O-ring seal fits tightly at the connection through its radial compression force to form a stable seal. When the second cylinder is installed, a certain pre-pressure is applied to the seal ring to ensure that the seal ring is tightly fitted to the outer wall of the first cylinder before the second cylinder rotates. In this way, even during the rotation process, the seal ring can maintain sufficient compression force to prevent water intrusion. Through the above design, the second cylinder can not only rotate freely relative to the first cylinder, but also maintain good sealing performance during the rotation process, ensuring the waterproof effect of the connector and the reliability of the electrical connection under various environmental conditions. This design cleverly combines flexibility and sealing.

[0039] like Figures 1 to 6 As shown, the plug 2 is provided with an insert sleeve 8, and a first positioning structure is provided between the insert sleeve 8 and the waterproof sleeve 3. The first positioning structure includes a positioning protrusion 9 and a positioning groove 15 that is positioned and matched with the positioning protrusion 9. The positioning protrusion 9 is provided on the insert sleeve 8, and the positioning groove 15 is provided on the waterproof sleeve 3. The setting of the first positioning structure, through the cooperation of the positioning protrusion 9 and the positioning groove 15, can not only ensure the accurate alignment of the plug 2 and the socket 1 during the plugging process, avoid electrical safety hazards caused by misaligned connection, but also prevent the relative rotation of the plug 2 and the waterproof sleeve 3, reduce the possibility of external water entering when the plug 2 and the waterproof sleeve 3 rotate relative to each other, thereby maintaining the overall structural stability of the connector and the reliability of the electrical connection.

[0040] In this embodiment, there are four positioning protrusions 9 and four positioning grooves 15 , and the positioning protrusions 9 and the positioning grooves 15 correspond to each other one by one. The four positioning protrusions 9 are arranged at intervals along the circumference of the insert tube 8 , and the positioning grooves 15 are arranged at intervals along the circumference of the waterproof tube 3 .

[0041] In other embodiments, the positioning groove 15 is provided on the inserting tube 8 , and the positioning protrusion 9 is provided on the waterproof tube 3 .

[0042] like Figures 1 to 6 As shown, the plug 2 is provided with an insert sleeve 8, and a second positioning structure is provided between the insert sleeve 8 and the waterproof cylinder 3, and the second positioning structure includes a positioning groove 10 and a positioning member that can be floated. The positioning member floats to have a positioning position extending into the positioning groove 10 and an escape position detached from the positioning groove 10. The positioning groove 10 is provided on the insert sleeve 8, and the positioning member is provided on the waterproof cylinder 3. The adoption of the second positioning structure, that is, the combination of the positioning groove 10 and the floating positioning member, realizes the position locking between the insert sleeve 8 and the waterproof cylinder 3. The floating positioning member can automatically extend into the positioning groove 10 when inserted to ensure the stability of the connection, and when the plug 2 needs to be unplugged, the positioning member can float to the escape position to avoid the plug 2 from being disengaged from the waterproof cylinder 3. This design makes the connection and disconnection operations of the plug 2 and the waterproof cylinder 3 more convenient, while ensuring the tightness and safety of the connection.

[0043] In other embodiments, the positioning piece is disposed on the inserting tube 8 , and the positioning groove 10 is disposed on the waterproof tube 3 .

[0044] like Figures 1 to 6 As shown, when the positioning member is arranged on the waterproof cylinder 3, a receiving groove 17 is arranged on the waterproof cylinder 3, and the positioning member includes an elastic member 18 arranged in the receiving groove 17 and a floating block 16 connected to the first end of the elastic member 18, and the second end of the elastic member 18 is connected to the bottom wall of the receiving groove 17. When the positioning member is arranged on the waterproof cylinder 3, the positioning member can quickly switch between the positioning position and the avoidance position through the combination of the elastic member 18 and the floating block 16. This fast-response positioning mechanism not only improves the flexibility of the connector, but also ensures the positioning accuracy under various operating conditions. In addition, the provision of the elastic member 18 enables the positioning member to be buffered when subjected to external force, reduces positioning failures caused by impact, and further improves the overall performance and service life of the connector.

[0045] In this embodiment, the receiving groove 17 is a cylindrical groove, the positioning groove 10 is an arc groove, and the floating block 16 is a sphere. There are four positioning members and four positioning grooves 10. The positioning groove 10 is arranged between two adjacent positioning protrusions 9, and the positioning member is arranged between two adjacent positioning grooves 15.

[0046] In this embodiment, in order to ensure that the plug can maintain conductive connection when rotating relative to the socket, the present invention adopts the following specific structural design:

[0047] 1. Use a rotating conductive ring structure: A rotating conductive ring is designed at the rear end of the plug 2, and the conductive ring is connected to the electrode inside the plug. At the same time, a fixed conductive ring or conductive contact that matches the rotating conductive ring is provided at the front end of the socket 1. This design ensures that even if the plug rotates relative to the socket, the contact between the conductive ring and the contact is still maintained, ensuring the continuous transmission of electrical signals or currents.

[0048] 2. Multi-contact design of conductive ring: Both the rotating conductive ring and the fixed conductive ring or contact are designed as a multi-contact structure, that is, multiple conductive contacts are arranged on the circumference of the conductive ring, which not only increases the contact area of ​​the contacts and improves the stability of the electrical connection, but also when the plug rotates, at least one or more pairs of contacts remain in contact, avoiding the circuit breaker problem caused by rotation.

[0049] 3. Conductive ring material selection: The conductive ring is made of highly conductive and wear-resistant materials, such as copper or gold-plated copper, to ensure good conductivity and reliability in long-term use. At the same time, the gold-plated layer can prevent oxidation and corrosion, further enhancing the stability and durability of the connection.

[0050] 4. Use spring contacts: The contacts in the fixed conductive ring are designed as elastic contacts, such as spring contacts. This type of contact can automatically adjust the pressure of contact with the rotating conductive ring, and maintain stable contact even when the plug rotates slightly, avoiding signal or current transmission interruption caused by poor contact.

[0051] 5. Brush and slide rail design: Another structure is to design the brush on the plug and the slide rail inside the socket. The brush keeps in contact with the slide rail through a spring or other elastic element. Even if the plug rotates, the brush can slide on the slide rail to maintain electrical connection. This design is also suitable for occasions where the plug needs to be rotated frequently, such as the connection of electric mechanical equipment.

[0052] In summary, through the design of rotating conductive ring, multi-contact design, selection of high-conductivity materials, spring contacts, brushes and slide rails, the connector of the present invention can maintain a stable conductive connection when the plug rotates relative to the socket, avoiding electrical connection problems caused by rotation, and greatly improving the flexibility and reliability of the connector. This design is particularly suitable for scenarios where wiring needs to be done in a limited space or the plug angle needs to be adjusted, such as electric vehicle charging interfaces, outdoor energy storage systems, etc.

[0053] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
