[0030] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following is described in conjunction with the embodiments and with reference to the drawings.

[0031] Please refer to Figures 1 to 7 , an energy storage connector, including a socket 1 and a plug 2. The socket 1 includes a socket housing 11, a socket conductor 12 and a rotating ring 13 disposed within the socket housing 11. The rotating ring 13 is sleeved on the socket conductor 12 and can rotate about the axial direction of the socket conductor 12. A plurality of slots 131 are uniformly distributed on the peripheral wall of the rotating ring 13. The plug 2 includes a plug housing 21, a plug conductor 22 and a protective cover 23 respectively disposed within the plug housing 21. A plurality of ribs 231 that cooperate with the slots 131 are uniformly distributed on the outer peripheral surface of the protective cover 23.

[0032] As can be seen from the above description, the beneficial effects of the present invention are as follows: The energy storage connector of the present invention can prevent the plug 2 of different polarities from being misinserted into the socket 1 through the cooperation of the slots 131 on the rotating ring 13 and the ribs 231 on the protective cover 23. Further, the rotating ring 13 can rotate relative to the socket conductor 12, enabling the rotating ring 13 to adjust its own position by rotation, so as to accurately align with the protective cover 23, and further enabling the plug 2 and the socket 1 to achieve 360° arbitrary angle plugging, which is convenient for the user to plug.

[0033] Further, annular grooves 121 and limiting protrusions 132 that cooperate with the annular grooves 121 are respectively provided on the contact surfaces of the socket conductor 12 and the rotating ring 13.

[0034] As can be seen from the above description, the rotational connection manner between the socket conductor 12 and the rotating ring 13 is simple, which is convenient for production and assembly.

[0035] Further, the rotating ring 13 includes a ring body 133 and a plurality of insertion rods 134 disposed on the ring body 133. The ring body 133 is sleeved on the socket conductor 12. The plurality of insertion rods 134 are uniformly arranged circumferentially around the ring body 133, and the slots 131 are formed between two adjacent insertion rods 134.

[0036] As can be seen from the above description, the structure of the rotating ring 13 is simple and convenient for production and manufacturing. Using the slots 131 formed between two adjacent insertion rods 134 can reduce the thickness of the peripheral wall of the rotating ring 13, which is beneficial to making the internal structure of the socket 1 more compact.

[0037] Further, a buckle 211 is provided on the side wall of the plug housing 21, and an annular boss 111 corresponding to the buckle 211 is provided on the outer wall surface of the socket housing 11.

[0038] As described above, after the plug 2 is inserted into the socket 1, the buckle 211 will engage with the annular boss 111, thereby enhancing the connection tightness between the plug 2 and the socket 1 and reducing the risk of accidental separation of the plug 2 and the socket 1 under external force.

[0039] Furthermore, the buckle 211 includes a latching portion 2111, a connecting portion 2112, and a pressing portion 2113 that are connected in sequence. The connecting portion 2112 is connected to the socket housing 11. A convex block is provided on the inner side of the latching portion 2111 corresponding to the annular boss 111, and the convex block extends into the inner cavity of the socket housing 11.

[0040] As described above, the structure of the buckle 211 is simple and convenient for production and manufacturing.

[0041] Furthermore, the plug housing 21 has a communicating insertion cavity and an access cavity. The plug conductor 22 is disposed in the insertion cavity. The access cavity communicates with one end face of the plug housing 21 to form a cable socket for the cable 3 to be inserted. A clamping area 24 for clamping the cable lug 31 is formed between the plug conductor 22 and the inner wall surface of the access cavity.

[0042] As described above, the plug 2 fixes the cable lug 31 by means of clamping, which is beneficial to simplifying the structure of the plug 2 and improving the insertion efficiency of the plug 2 and the cable 3.

[0043] Furthermore, the plug 2 further includes a fixing member 25. The fixing member 25 includes a limiting stop arm 251 and an annular fixing portion 252. The fixing portion 252 is disposed inside the cable socket. The fixing portion 252 protrudes inward to form the limiting stop arm 251. One end face of the limiting stop arm 251 away from the fixing portion 252 is used to abut against the cable lug 31.

[0044] Furthermore, a wedge-shaped structure 2511 is provided on the inner side surface of the limiting stop arm 251.

[0045] As described above, during the process of inserting the cable lug 31 into the plug 2, it will abut against the wedge-shaped structure 2511 of the limiting stop arm 251, causing the limiting stop arm 251 to bend and deform so that the cable lug 31 can be smoothly inserted into the clamping area 24. After the cable lug 31 is inserted into the clamping area 24, the limiting stop arm 251 deforms and resets, and the end face of the limiting stop arm 251 will abut against the cable lug 31, thereby preventing the cable lug 31 from withdrawing from the plug 2.

[0046] Further, the plug 2 further includes a rear cover 26. A cable seal 27 is further provided inside the cable socket. The rear cover 26 includes an annular assembly portion 261 and a limiting portion 262 formed by bending and extending inward from the assembly portion 261. The assembly portion 261 is sleeved on one end of the plug housing 21 provided with the cable socket and is detachably connected to the plug housing 21.

[0047] As can be seen from the above description, the seal can prevent external water vapor, oil stains, foreign objects, etc. from entering the plug 2 through the gap between the plug 2 and the cable 3, which is beneficial to ensuring the stable conduction between the plug conductor 22 and the cable 3 and extending the service life of the plug conductor 22 and the cable lug 31.

[0048] Further, a clamping block 212 and a clamping groove 2611 cooperating with the clamping block 212 are respectively provided on the contact surface between the assembly portion 261 and the plug housing 21.

[0049] As can be seen from the above description, the connection method between the assembly portion 261 and the plug housing 21 is simple and convenient, facilitating disassembly and assembly.

[0050] Embodiment 1

[0051] Please refer to Figures 1 to 7 , Embodiment 1 of the present invention is: an energy storage connector for realizing electrical connection between components that are electrically independent of each other.

[0052] The energy storage connector includes a socket 1 and a plug 2. The socket 1 includes a socket housing 11, a socket conductor 12 and a rotating ring 13 provided inside the socket housing 11. The rotating ring 13 is sleeved on the socket conductor 12 and can rotate around the axial direction of the socket conductor 12. A plurality of slots 131 are uniformly distributed on the circumferential wall of the rotating ring 13. The plug 2 includes a plug housing 21, a plug conductor 22 and a protective cover 23 respectively provided inside the plug housing 21. A plurality of ribs 231 cooperating with the slots 131 are uniformly distributed on the outer circumferential surface of the protective cover 23.

[0053] Specifically, as Figure 3As shown, one end of the socket conductor 12 close to the plug 2 is cylindrical, and the socket housing 11, the socket conductor 12, and the rotating ring 13 are coaxially arranged. The rotating ring 13 is arranged between the socket conductor 12 and the inner wall of the socket housing 11, and the outer peripheral surface of the rotating ring 13 is adapted to the inner peripheral surface of the socket housing 11. The plug 2 is L-shaped and includes a connected insertion portion and a conduction portion. The insertion portion has an insertion cavity, and the conduction portion has an access cavity. One end of the insertion cavity communicates with the access cavity, and the other end communicates with the end face of the plug 2 to form an insertion port for inserting the socket 1. The plug conductor 22 and the protective cover 23 are arranged in the insertion cavity. The protective cover 23 is cylindrical, and the protective cover 23 is sleeved on one end of the plug conductor 22 close to the socket 1. One end of the rib 231 of the protective cover 23 close to the socket 1 is provided with a rounded corner to facilitate the insertion of the rib 231 into the slot 131. A plug seal 28 is also provided between the end face of the protective cover 23 away from the socket 1 and the inner wall of the plug 2. The plug conductor 22 is cylindrical with one end closed, and a crown spring 221 is provided on the inner peripheral surface of the plug conductor 22. An insulating cap 29 is also provided inside the crown spring 221. The insulating cap 29 includes an annular mounting portion 291 and a plurality of barbs 292 uniformly arranged on the mounting portion 291. The insertion portion, the protective cover 23, the plug conductor 22, the crown spring 221, and the insulating cap 29 are coaxially arranged. An annular groove for cooperating with the plurality of barbs 292 is provided on the inner peripheral surface of the socket conductor 12. The outer diameter of the socket conductor 12 is smaller than the inner diameter of the plug conductor 22. After the plug 2 and the socket 1 are inserted, the socket conductor 12 is inserted into the plug conductor 22, and the outer peripheral surface of the socket conductor 12 is pressed by the crown spring 221, so that the socket conductor 12 and the plug conductor 22 can be stably conducted. The annular groove on the inner peripheral surface of the socket conductor 12 is hooked with the plurality of barbs 292 of the insulating cap 29 to further prevent the socket 1 and the plug 2 from disconnecting. An anti-touch finger insulating rod 4 is also provided inside the insulating cap 29. The anti-touch finger insulating rod 4 is not in contact with the plug conductor 22, and one end of the anti-touch finger insulating rod 4 protrudes from the end face of the plug conductor 22 close to the socket 1 to prevent the user's finger from accidentally touching the plug conductor 22 and causing an accident. It is easy to understand that the number of slots 131 is an integer multiple of the number of ribs 231. By adjusting the widths of the ribs 231 of the plug 2 with different polarities and the slots 131 of the socket 1, the ribs 231 of the positive plug 2 are adapted to the slots 131 of the positive socket 1, and the ribs 231 of the negative plug 2 are adapted to the slots 131 of the negative socket 1, so as to prevent the plug 2 and the socket 1 with different polarities from being inserted into each other.

[0054] Preferably, as Figure 5As shown, the rotating ring 13 includes a ring body 133 and a plurality of insertion rods 134 provided on the ring body 133. The ring body 133 is sleeved on the socket conductor 12. A ring groove 121 and a limiting protrusion 132 matching the ring groove 121 are respectively provided on the contact surface between the socket conductor 12 and the ring body 133. The plurality of insertion rods 134 are evenly arranged around the circumference of the ring body 133, and a slot 131 is formed between two adjacent insertion rods 134. Specifically, the outer wall surface of the insertion rod fits with the inner wall surface of the socket housing 11. It is easy to understand that in this embodiment, the slot 131 is formed between two adjacent insertion rods 134 instead of opening a long groove on the inner circumferential surface of the rotating ring 13, which can effectively reduce the thickness of the peripheral wall of the rotating ring 13 and is beneficial to making the internal structure of the socket 1 more compact. The end of the insertion rod close to the plug 2 is provided with an inclined chamfer to facilitate the convex rib 231 to be inserted into the slot 131. In this embodiment, a ring groove 121 is provided on the outer circumferential surface of the socket conductor 12, and a limiting protrusion 132 is provided on the inner circumferential surface of the ring body 133. In other embodiments, it can be set that a limiting protrusion 132 is provided on the outer circumferential surface of the socket conductor 12, and a ring groove 121 is provided on the inner circumferential surface of the ring body 133. The number of the limiting protrusions 132 is multiple, and the multiple limiting protrusions 132 are evenly distributed around the circumference of the ring body 133. The cross section of the limiting protrusion 132 is triangular or trapezoidal to facilitate the ring body 133 to slide along the socket conductor 12 until the limiting protrusion 132 is snapped into the ring groove 121.

[0055] Preferably, as Figure 1 , Figure 3 and Figure 4 shown, a buckle 211 is respectively provided on both side walls of the insertion part of the plug housing 21, and an annular boss 111 corresponding to the buckle 211 is provided on the outer wall surface of the socket housing 11. It is easy to understand that after the plug 2 is inserted into the socket 1, the buckle 211 will be buckled with the annular boss 111, thereby enhancing the connection tightness between the plug 2 and the socket 1 and reducing the risk of accidental separation of the plug 2 and the socket 1 under the action of external force. Specifically, the buckle 211 includes a buckling part 2111, a connecting part 2112 and a pressing part 2113 connected in sequence. The connecting part 2112 is connected to the socket housing 11. A convex block is provided on the inner side of the buckling part 2111 corresponding to the annular boss 111, and the convex block extends into the inner cavity of the socket housing 11. An anti-slip structure is provided on the outer wall surface of the pressing part 2113. In this embodiment, two U-shaped long holes are respectively opened on both side walls of the insertion part of the plug housing 21. The openings of the two U-shaped long holes face each other. The inner sides of the two U-shaped long holes respectively form the buckling part 2111 and the pressing part 2113, and the connecting part 2112 is formed between the two U-shaped long holes. It is easy to understand that when it is necessary to disconnect the plug 2 from the socket 1, the user only needs to press the two pressing parts 2113 on both sides of the plug 2, so that the end of the buckling part 2111 provided with the convex block bends and deforms in a direction away from the socket 1, and the convex block no longer limits the annular boss 111, so that the plug 2 can be smoothly separated from the socket 1.

[0056] Preferably, as Figure 2 and Figure 7 shown, one end face of the access cavity communicating with the plug housing 21 forms a cable socket for the cable 3 to be inserted, and a clamping area 24 for clamping the cable lug 31 is formed between the plug conductor 22 and the inner wall surface of the access cavity. Specifically, a protruding pressing block 213 is provided on the inner wall of the access cavity away from the cable socket. The length direction of the pressing block 213 is parallel to the axial direction of the access cavity. A clamping area 24 is formed between the pressing block 213 and the end face of the plug conductor 22. One end of the pressing block 213 close to the cable socket is beveled to facilitate the insertion of the cable lug 31 into the clamping area 24. A plurality of reinforcing ribs are provided on the pressing block 213 to increase the elastic modulus of the pressing block 213, so that the pressing block 213 can press the cable lug 31 more tightly against the plug conductor 22. It is easy to understand that in this embodiment, the plug 2 fixes the cable lug 31 by clamping. Compared with connecting the cable lug 31 and the plug conductor 22 by screws, the clamping method can effectively simplify the structure of the plug 2 and improve the insertion efficiency of the plug 2 and the cable 3.

[0057] Preferably, as Figure 6 and Figure 7 shown, the plug 2 further includes a fixing member 25. The fixing member 25 includes a limiting stop arm 251 and an annular fixing portion 252. The fixing portion 252 is provided inside the cable socket. The fixing portion 252 protrudes inward to form a limiting stop arm 251. The end face of the limiting stop arm 251 away from the fixing portion 252 is used to abut against the cable lug 31, and a wedge-shaped structure 2511 is provided on the inner side surface of the limiting stop arm 251. Specifically, a limiting shoulder for limiting the fixing portion 252 is provided on the inner wall of the plug housing 2. The two sides of the cable lug 31 protrude from the cable 3, so that limiting areas for abutting against the limiting stop arm 251 are formed on both sides of the end face of the cable lug 31. In this embodiment, the length direction of the limiting stop arm 251 is parallel to the axial direction of the access cavity, and the number of the limiting stop arms 251 is two. It is easy to understand that during the process of inserting the cable lug 31 into the access cavity, the cable lug 31 will abut against the wedge-shaped structure 2511 of the limiting stop arm 251, causing the limiting stop arm 251 to bend and deform so that the cable lug 31 can continue to be inserted into the clamping area 24. After the cable lug 31 is inserted into the clamping area 24, the limiting stop arm 251 deforms and resets, and the end face of the limiting stop arm 251 will abut against the end face of the cable lug 31, thereby preventing the cable lug 31 from withdrawing from the plug 2.

[0058] Preferably, as Figure 2 、 Figure 6 and Figure 7As shown, the plug 2 further includes a rear cover 26. A cable seal 27 is further provided inside the cable socket. The rear cover 26 includes an annular assembly portion 261 and a limiting portion 262 formed by bending and extending inward from the assembly portion 261. The assembly portion 261 is sleeved on one end of the plug housing 21 provided with the cable socket and is detachably connected to the plug housing 21. Specifically, the cable seal 27 is provided with a through hole for the cable 3 to pass through. The cable seal 27 is arranged between the limiting portion 262 and the fixing portion 252. The assembly portion 261 is also provided with a plurality of notches to facilitate the bending and deformation of the assembly portion 261, so as to facilitate the assembly portion 261 to be sleeved on one end of the plug housing 21.

[0059] In this embodiment, as Figure 3 and Figure 6 shown, a wedge-shaped clamping block 212 is respectively provided on the outer wall surfaces on both sides of the plug housing 21. The assembly portion 261 is provided with a clamping groove 2611 that cooperates with the clamping block 212. In other embodiments, it can be set that a plurality of clamping blocks 212 are provided on the inner circumferential surface of the assembly portion 261, and a clamping groove 2611 that cooperates with the clamping block 212 is provided on the outer wall surface of the plug housing 21.

[0060] In summary, the energy storage connector provided by the present invention can prevent the misinsertion of plugs and sockets with different polarities through the cooperation of the slots on the rotating ring and the ribs on the protective cover. Preferably, the rotating ring can rotate relative to the socket conductor, so that the rotating ring can rotate to adjust its own position, so as to accurately align with the protective cover, and further enable the plug and the socket to be inserted at any angle of 360°, which is convenient for the user to insert.

[0061] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
