Description
Technical Field
[0001] The utility model relates to the technical field of connectors, and more specifically, to a high-voltage and high-current connector for energy storage. Background Art
[0002] Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. High-current connectors are important accessories in the energy storage process. High-current connectors can quickly connect and disconnect electrical circuits in some high-power situations where high current transmission is required.
[0003] During the electric energy storage process, in order to quickly connect and disconnect the electrical circuit, when a high-current connector is needed for assistance, the plug and socket are first docked to form a complete high-current connector, and then the high-current connector is docked with the circuit. However, when the connector is in use, each connector is often assembled with the wire line by first fixing one end and then fixing the other end. This can easily lead to the problem that the wire is slightly longer or shorter when assembling the other end. Since the existing connector plug and socket cannot rotate freely after assembly, it is easy to cause the wire to be squeezed or twisted to a certain extent, which is not conducive to assembly, and it is also impossible to conveniently adjust the position during assembly, which has a certain impact on its user experience and lifespan. Moreover, since the plug and socket of the traditional connector cannot be rotated after being plugged in, it is difficult to adjust the direction of the cable after high current wiring.

[0030] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. That is, the present invention is not limited to the described embodiments.
[0031] In order to better understand the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments:
[0032] See also Figure 1As shown, a high-voltage and high-current connector for energy storage includes a rotating component 1, a socket 2 and a plug 3, wherein the plug 3 and the socket 2 are connected through the rotating component 1.
[0033] See also Figures 2 to 4 As shown, the socket 2 includes a main body 21 and a pin 22. The rotating member 1 is movably installed on the main body 21. The main body 21 is connected to the plug 3 through the rotating member 1 so that the plug 3 can rotate relative to the socket 2. With this design, the plug 3 can achieve a 360° rotation function relative to the socket 2. Specifically, the plug 3 can rotate freely after being inserted into the connector, which can flexibly output and distribute wires, meet different installation requirements, and improve installation efficiency.
[0034] In this embodiment, in order to enable the rotating member 1 to be movably installed on the main body 21 so that the rotating member 1 can rotate relative to the main body 21, an annular groove 215 is provided on the outer wall of the main body 21, and a corresponding clamping block 13 is configured on the inner wall of the rotating member 1. When the rotating member 1 is installed on the main body 21, the clamping block 13 is clamped in the annular groove 215, ensuring the stability of the connection between the rotating member 1 and the main body 21 and preventing accidental falling off due to external force or vibration; and the clamping block 13 can slide in the annular groove 215. This design enables the rotating member 1 to have a 360° rotation function. When the plug 3 is connected to the socket 2 through the rotating member 1, the plug 3 can be rotated relative to the socket 2 to adjust the outlet direction of the cable 5, greatly improving the flexibility during wiring, especially in scenarios where space is limited or the direction of the cable 5 needs to be adjusted, the plug 3 can be easily rotated to the optimal angle for connection, without the need to adjust the direction of the cable 5 by repeated plugging and unplugging, thereby saving time and labor costs.
[0035] The plug 3 of the high-voltage and high-current energy storage connector provided in the embodiment of the present invention not only has a 360° rotation function, but also has a secondary locking function. The structure for realizing the secondary locking function is as follows:
[0036] See also Figure 4 As shown, a first plug cavity 211 is provided in the main body 21, the pin 22 is installed in the main body 21 and at least a portion of the pin 22 extends into the first plug cavity 211, and a plurality of first limiting protrusions 212 are provided at the bottom of the first plug cavity 211; Figure 5 and Figure 6As shown, the plug 3 includes a shell 31 and a jack assembly 32, and the jack assembly 32 is arranged in the shell 31. The shell 31 includes a shell body 311 and a plug-in portion 312. A plurality of second limiting protrusions 3121 are provided at the end of the plug-in portion 312. When the plug 3 is rotated to a predetermined position so that the outlet direction of the cable 5 meets the requirements, the plug 3 is pressed again, causing the first limiting protrusion 212 to be inserted into the gap between two adjacent second limiting protrusions 3121, so that a secondary locking is achieved between the plug 3 and the socket 2.
[0037] In this embodiment, the jack assembly 32 includes a first base 321 and a second base 322 . The first base 321 and the second base 322 are fixedly connected. The first base 321 is used to connect to the pin 22 , and the second base 322 is used to connect to the cable 5 .
[0038] In this embodiment, when the plug 3 and the socket 2 are plugged in, there are two states between the plug 3 and the socket 2, namely a rotating state and a locked state. When the plug 3 and the socket 2 are in the rotating state, the plug 3 can be pressed again to switch the rotating state between the plug 3 and the socket 2 to the locked state.
[0039] It should be noted that the one-time locking in the embodiment of the present invention refers to the connection between the plug 3 and the socket 2 via the rotating member 1 .
[0040] See also Figure 2 and Figure 5As shown, the outer wall of the rotating member 1 is provided with a plurality of first latch teeth 11, and a first latch groove 12 is formed between two adjacent first latch teeth 11. The gap between the shell body 311 and the plug-in portion 312 forms a second plug-in cavity 313. The inner wall of the second plug-in cavity 313 is provided with a plurality of second latch teeth 314, and a second latch groove 315 is formed between two adjacent second latch teeth 314. When the socket 2 and the plug 3 are plugged in, the plug-in portion 312 is inserted into the first plug-in cavity 211, and the first latch teeth 11 are located in the second latch groove 315, and the second latch teeth 314 are located in the first latch groove 12. This design can prevent incorrect connection between the plug 3 and the socket 2 during the insertion process, especially in multi-port or multi-polarity connectors. The precisely matched positional relationships between the first latch 11 and the second latch slot 315, and the second latch 314 and the first latch slot 12, ensure that only the correct plug 3 can be inserted into the corresponding socket 2, thereby avoiding equipment damage or safety risks caused by incorrect insertion. The operation is simple, and correct connection can be achieved by simply following the natural guidance of the latch and the latch slot, which reduces the difficulty of operation, thereby making the high-voltage, high-current energy storage connector provided by this embodiment have a fool-proof function. Secondly, when the plug 3 and the socket 2 do not match, the inconsistent product key positions (first latch 11 and second latch 314) can ensure that the pin 22 and the socket will not contact each other under any circumstances. Only when the plug 3 and the socket 2 are fully matched and correctly inserted will the pin 22 and the socket contact and connect, thereby effectively preventing the occurrence of short circuits, protecting the electrical safety of the connector and the connected equipment, and making the high-voltage, high-current energy storage connector provided by this embodiment have a short-circuit prevention function.
[0041] See also Figure 4 As shown, the pin 22 in this embodiment includes a first section 221 and a second section 222. The first section 221 and the second section 222 form an integral structure. The first section 221 is located within the first insertion cavity 211. A protective cap 23 is provided at the end of the first section 221, and the length of the first section 221 is less than the depth of the first insertion cavity 211. This design effectively prevents a user's finger from directly contacting the pin 22 during operation or accidental contact. As a key component in electrical connection, the exposed conductive portion of the pin 22 can cause electric shock if directly touched. Therefore, the provision of the protective cap 23 improves the safety of the high-voltage, high-current energy storage connector. Furthermore, the depth of the first insertion cavity 211 is significantly greater than the length of the first section 221, ensuring that even if the protective cap 23 fails or is absent for some reason, a user's finger will find it difficult to contact the pin 22, thereby significantly enhancing the overall safety of the high-voltage, high-current energy storage connector.
[0042] In this embodiment, in order to enhance the waterproof and dustproof effects of the high-voltage and high-current connector for energy storage, the pin 22 in the embodiment of the utility model is provided with a groove arranged around the outer wall of the pin 22, and the groove is provided with a first sealing ring 24. The first sealing ring 24 is used to seal the gap between the pin 22 and the main body 21. When the plug 3 and the socket 2 are connected, the first sealing ring 24 can prevent dust or water vapor from entering the first plug-in cavity 211, thereby ensuring the stability of the electrical connection between the plug 3 and the socket 2.
[0043] Specifically, the main body 21 includes a mounting base 213 and a columnar body 214 integrally formed with the mounting base 213. The mounting base 213 surrounds at least a portion of the outer wall of the columnar body 214. A recess is provided on one side of the mounting base 213, and a rubber gasket 25 is disposed within the recess. The rubber gasket 25 is used to seal the gap between the chassis panel 4 and the mounting base 213. When the mounting base 213 of the socket 2 is mounted to the chassis panel 4 via bolts, the rubber gasket 25 tightly fits the chassis panel 4, thereby providing a sealing effect.
[0044] See also Figure 7 As shown, the plug 3 in this embodiment also includes a tail cap 33, a wire seal 34 and a gasket 35 disposed within the tail cap 33. One end of the tail cap 33 is provided with a jack for inserting the cable 5, and the other end of the tail cap 33 is open. The inner wall of the tail cap 33 is provided with an internal thread, and the outer wall of the outer shell 31 is provided with an external thread. The tail cap 33 is mounted on the outer shell 31 through the open end, and the internal threads of the tail cap 33 and the external threads of the outer shell 31 are engaged. In this embodiment, the wire seal 34 is used to seal the gap between the tail cap 33 and the cable 5, thereby preventing moisture, dust, etc. from entering the interior of the high-voltage, high-current energy storage connector.
[0045] Preferably, an annular groove is provided on the outer wall of the shell 31, and a second sealing ring 36 is embedded in the annular groove. The second sealing ring 36 is used to seal the gap between the shell 31 and the tail cover 33; a waterproof ring 316 is provided at one end of the plug-in portion 312 protruding from the shell body 311. The waterproof ring 316 is embedded on the outer wall of the plug-in portion 312. The waterproof ring 316 is used to seal the gap between the plug-in portion 312 and the main body 21; in this embodiment, the first sealing ring 24 and the second sealing ring 36 are both O-rings.
[0046] Through the above structural design, the high-voltage and high-current connector for energy storage provided by the embodiment of the utility model can meet the IP68 protection level requirements, can work normally in harsh environments, and effectively prevent the intrusion of water and dust.
