Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and more specifically, to an energy storage connector. Background Art

[0002] High-current energy storage systems play a vital role in the development and popularization of green energy. Their core function is to store new energy electricity such as that generated by photovoltaic power generation systems, and then supply it to civil or commercial new energy power supply systems, covering urban rail transit, new energy vehicle charging stations, large-scale power equipment and automation control systems. Integrating energy storage links in the power production system can effectively implement demand-side management, achieve load peak shaving and valley filling and smoothing, thereby improving the utilization efficiency of power equipment, reducing power supply costs, and promoting the application of renewable energy. With the rapid progress of renewable energy, energy storage technology has become a key solution to energy storage and scheduling problems, and the demand for energy storage connectors has continued to grow. As a key connecting component between energy storage devices and power systems, energy storage connectors bear the important responsibility of energy transmission. Their quality and performance are directly related to the stability and safe operation of the entire energy storage system.

[0003] Energy storage systems are generally composed of multiple groups of batteries connected in series and parallel to obtain the required voltage and current. At this time, cables are needed to connect the batteries. The two ends of the cable are connected to connector plugs. The connector socket is installed on the battery assembly housing. When the plug is inserted into the socket, the connection between the batteries is achieved.

[0004] However, when the connector is in use, each connector and the wire line are often assembled by first fixing one end and then fixing the other end. This can easily cause the wire to be 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. It is also impossible to adjust the position during assembly, which has a certain impact on its use experience and life. 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. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an energy storage connector, which can not only rotate freely 360° when plugged in to facilitate flexible wiring, but also has a secondary locking function.

[0031] 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 cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the described embodiments.

[0032] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0033] See also Figure 1 As shown, an energy storage connector comprises a rotating member 1, a socket 2 and a plug 3, wherein the plug 3 and the socket 2 are connected via the rotating member 1.

[0034] See also Figure 2 to Figure 4 As shown, the socket 2 includes a main body 21 and a pin 22, and a rotating member 1 is movably mounted 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, and can flexibly output and distribute wires to meet different installation requirements and improve installation efficiency.

[0035] 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 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 block 13 is engaged in the annular groove 215, ensuring the connection stability between the rotating member 1 and the main body 21, and preventing accidental falling off due to external force or vibration; and the block 13 can slide in the annular groove 215. Such a 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, which greatly improves the flexibility of wiring. In particular, 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.

[0036] The plug 3 of the 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:

[0037] See also Figure 4 As shown, a first plug cavity 211 is provided in the main body 21, the plug pin 22 is installed in the main body 21 and at least a part of the plug 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; see Figure 5 and Figure 6 As shown, the plug 3 includes a shell 31 and a jack assembly 32, the jack assembly 32 is arranged in the shell 31, the shell 31 includes a shell body 311 and a plug-in portion 312, and a plurality of second limiting protrusions 3121 are arranged 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 to cause the first limiting protrusion 212 to be inserted into the gap between two adjacent second limiting protrusions 3121, so that secondary locking is achieved between the plug 3 and the socket 2.

[0038] 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 .

[0039] 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.

[0040] 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 .

[0041] See also Figure 2 and Figure 5 As shown, a plurality of first latch teeth 11 are provided on the outer wall of the rotating member 1, a first latch groove 12 is formed between two adjacent first latch teeth 11, a second plug-in cavity 313 is formed in the gap between the shell body 311 and the plug-in portion 312, a plurality of second latch teeth 314 are provided on the inner wall of the second plug-in cavity 313, 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, 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. Such a design can prevent the plug 3 and the socket 2 from being incorrectly connected during the plugging process, especially in a multi-interface or multi-polarity connector, by accurately matching the positional relationship between the first latch 11 and the second latch groove 315, and the second latch 314 and the first latch groove 12, it is ensured 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 the correct connection can be achieved only according to the natural guidance of the latch and the latch groove, which reduces the difficulty of operation, so that the energy storage connector provided by this embodiment has a foolproof function; secondly, when the plug 3 and the socket 2 do not match, due to the inconsistency of the product key positions (the first latch 11 and the second latch 314), it can be ensured that the pin 22 and the socket will not contact under any circumstances. Only when the plug 3 and the socket 2 are completely matched and correctly inserted, the pin 22 and the socket are in contact and connected, thereby effectively preventing the occurrence of a short circuit, protecting the electrical safety of the connector and the connected equipment, and making the energy storage connector provided by this embodiment have an anti-short circuit function.

[0042] See also Figure 4 As shown, the plug pin 22 in this embodiment includes a first section 221 and a second section 222, the first section 221 and the second section 222 are an integrated structure, the first section 221 is located in the first plug cavity 211, and 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 plug cavity 211. In this design, by providing the protective cap 23 at the end of the first section 221 of the plug pin 22, it is effectively prevented that the user's fingers directly touch the plug pin 22 during operation or accidental touch. The plug pin 22 is a key component of electrical connection. If its exposed conductive part is directly touched, it may cause electric shock injury. Therefore, the provision of the protective cap 23 improves the safety of the energy storage connector. Secondly, the depth of the first plug cavity 211 is much greater than the length of the first section 221, ensuring that even if the protective cap 23 fails or does not exist for some reason, it is difficult for the user's fingers to touch the plug pin 22, thereby greatly enhancing the overall safety of the energy storage connector.

[0043] In this embodiment, in order to enhance the waterproof and dustproof effects of the energy storage connector, the pin 22 in the embodiment of the present invention 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 and matched, 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.

[0044] Specifically, the main body 21 includes a mounting base 213 and a columnar body 214 which is an integral structure 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. A rubber pad 25 is provided in the recess. The rubber pad 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 on the chassis panel 4 by bolts, the rubber pad 25 is tightly matched with the chassis panel 4 to achieve a sealing effect.

[0045] See also Figure 7 As shown, the plug 3 in this embodiment further includes a tail cover 33, a sealing body 34 and a gasket 35 arranged in the tail cover 33, one end of the tail cover 33 is provided with a jack for inserting the cable 5, and the other end of the tail cover 33 is an open mouth, the inner wall of the tail cover 33 is provided with an internal thread, and the outer wall of the shell 31 is provided with an external thread, and the tail cover 33 is sleeved on the shell 31 through the open mouth, and the internal thread of the tail cover 33 is meshed with the external thread of the shell 31. In this embodiment, the sealing body 34 is used to seal the gap between the tail cover 33 and the cable 5, so as to prevent water vapor, dust, etc. from entering the interior of the energy storage connector.

[0046] Preferably, an annular groove is provided on the outer wall of the outer 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 outer shell 31 and the tail cover 33; a waterproof ring 316 is provided at one end of the plug-in part 312 protruding out of the shell body 311, and the waterproof ring 316 is embedded on the outer wall of the plug-in part 312. The waterproof ring 316 is used to seal the gap between the plug-in part 312 and the main body 21; in the present embodiment, the first sealing ring 24 and the second sealing ring 36 are both O-rings.

[0047] Through the above structural design, the energy storage connector provided by the embodiment of the present invention can meet the IP68 protection level requirements, can work normally in harsh environments, and effectively prevent the intrusion of water and dust.
