Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, and more particularly to a photovoltaic connector. Background Art

[0002] In the current technological development of the photovoltaic industry, photovoltaic connectors are crucial components in photovoltaic systems. Their performance and structural design have a profound impact on the stable operation of the entire system. However, based on the existing technical conditions, there are some obvious deficiencies in the design and structure of photovoltaic connectors. These deficiencies limit the reliability and maintenance efficiency of photovoltaic systems to a certain extent.

[0003] First, existing photovoltaic connectors usually adopt a non-detachable structural design. This design means that once the components inside the connector are damaged or malfunction, users cannot replace the damaged components individually, but can only replace the entire connector. This design not only increases maintenance costs, but may also cause additional downtime during the replacement process, adversely affecting the continuous operation of the photovoltaic system.

[0004] To overcome the shortcomings of the non-detachable structure, some equipment manufacturers have tried to use a snap-on design to optimize the photovoltaic connector, making it a detachable structure. However, the snap-on connection method has certain limitations in actual use. When removing the connector, the user needs to press the snap inward. This process is not only laborious to operate, but also easily leads to users resorting to violent disassembly in an emergency. This violent disassembly method may damage the snap, thereby affecting the overall performance and life of the connector.

[0005] In addition, the internal structure design of existing detachable photovoltaic connectors is relatively simple, which leads to an incomplete protection mechanism at the connection of components. During long-term use, due to the influence of the outdoor environment, such as temperature changes, ultraviolet radiation and rain intrusion, the sealing performance of the connector may gradually decline, resulting in water seepage problems. Water seepage will not only directly affect the electrical performance of the connector, but may also cause internal circuit short circuit or corrosion, thereby seriously affecting the safety and reliability of the photovoltaic system.

[0032] One end of the male connector 1 and the female connector 5 are both connected with a threaded sleeve 13, and the two threaded sleeves 13 are detachably connected to the male connector 1 and the female connector 5 respectively through threads.

[0033] An anti-slip strip 14 is connected to the outer side of the threaded sleeve 13 .

[0034] A push spring 15 is provided on the outside of the male connector 1 , and both ends of the push spring 15 are connected to the male connector 1 and the adapter sleeve 9 respectively.

[0035] When the positive electrode 2 or negative electrode 3 is damaged and needs to be replaced, the adapter sleeve 9 is first pushed, and the adapter sleeve 9 will drive the adapter slot 8 to move. At the same time, the adapter sleeve 9 will squeeze the push spring 15 connected on one side, and then the side wall of the adapter slot 8 will squeeze one side of the matching plate 6, so that the matching plate 6 rotates in the movable slot 7 along the rotating shaft 11. At the same time, the matching plate 6 will drive the card plate 10 connected at one end to rotate, and then the card plate 10 will gradually disengage from the card slot 12 and enter the movable slot 7. When the push spring 15 is squeezed to the limit, the card plate 10 just enters the movable slot 7. At this time, the card plate 10 and the card slot 12 are no longer in a locking relationship. Then, the male connector 1 and the female connector 5 are pulled to both sides respectively, and the male connector 1 and the female connector 5 can be disassembled. Then, the threaded sleeves 13 connected at one end of the male connector 1 and the female connector 5 are removed respectively, and then the cable is disconnected from the positive pin 2 and the negative pin 3 respectively, and then the positive pin 2 and the negative pin 3 are removed from After the plug 1 is fully inserted into the socket 4, the adapter 9 is released, and the push spring 15 pushes the adapter 9 to reset, and the adapter 9 drives the adapter groove 8 to reset. Then, the other inner wall of the adapter groove 8 squeezes the other side of the matching plate 6, so that the matching plate 6 drives the card plate 10 to rotate along the rotating shaft 11, and then the card plate 10 moves out of the movable groove 7 and enters the card groove 12. When the push spring 15 is fully reset, the card plate 10 and the card groove 12 just form a tight locking relationship, thereby realizing the rapid assembly of the male connector 1 and the female connector 5, and then realizing the rapid replacement of internal components.

[0036] See also Figure 1-5 As an implementation method of the protection mechanism: the protection mechanism includes a sealing ring 16 and a sealing groove 17, the sealing groove 17 is respectively opened on the inner side of the male connector 1, the female connector 5 and the threaded sleeve 13, and the sealing ring 16 is installed in the corresponding sealing groove 17.

[0039] There are multiple sealing rings 19 and grooves 20, and the sealing rings 19, sealing rings 16 and gaskets 18 are all made of rubber.

[0040] More specifically, when the threaded sleeve 13 is tightened, the inner wall of the sealing groove 17 opened inside the threaded sleeve 13 and the inner wall of the sealing groove 17 opened inside the male joint 1 and the female joint 5 will compress the sealing ring 16, thereby sealing and protecting the joints between the threaded sleeve 13 and the male joint 1, and the threaded sleeve 13 and the female joint 5. When the female joint 5 is completely connected to the male joint 1, the outer wall of the female joint 5 will compress the gasket 18 to prevent water seepage at the joint between the female joint 5 and the male joint 1. At the same time, the multiple sealing rings 19 arranged on the outside of the female joint 5 will enter the corresponding grooves 20 for reset, so that the sealing rings 19 are engaged in the grooves 20. This design of multiple sealing structures further improves the sealing performance of the joints between the male joint 1 and the female joint 5.

[0041] In summary, when the overall device is in use or running: when the internal positive needle 2 or negative needle 3 is damaged and needs to be replaced, first push the adapter set 9, the adapter set 9 will drive the adapter slot 8 to move, and at the same time the adapter set 9 will squeeze the push spring 15 connected on one side, and then the side wall of the adapter slot 8 will squeeze one side of the matching plate 6, so that the matching plate 6 rotates in the movable slot 7 along the rotating shaft 11, and at the same time the matching plate 6 will drive the card plate 10 connected at one end to rotate, and then the card plate 10 will gradually disengage from the card slot 12 and enter the movable slot 7. When the push spring 15 is squeezed to the limit, the card plate 10 just enters the movable slot 7. At this time, the card plate 10 and the card slot 12 are no longer in a locking relationship. Then pull the male connector 1 and the female connector 5 to both sides respectively to separate the male connector 1 and the female connector 5. Then remove the threaded sleeves 13 connected at one end of the male connector 1 and the female connector 5 respectively, and then disconnect the cable from the positive pin 2 and the negative pin 3 respectively, and then connect the positive pin 2 and Take out the negative needle 3 from the installation slot 4, and then replace the positive needle 2 and the negative needle 3. After the replacement is completed, install the positive needle 2 and the negative needle 3 into the corresponding installation slot 4 respectively, and then pass the cable through the threaded sleeve 13 to connect with the positive needle 2 and the negative needle 3 respectively, and then tighten the two threaded sleeves 13 to one end of the female connector 5 and the male connector 1 respectively, and then insert the female connector 5 into the male connector 1. When the female connector 5 is fully inserted into the male connector 1, loosen the adapter sleeve 9 and push the spring 1. 5 will push the adapter set 9 to reset, and the adapter set 9 will drive the adapter slot 8 to reset, and then the other inner wall of the adapter slot 8 will squeeze the other side of the matching plate 6, so that the matching plate 6 will drive the clamping plate 10 to rotate along the rotating shaft 11, and then the clamping plate 10 will move out of the movable slot 7 and enter the clamping slot 12. When the push spring 15 is completely reset, the clamping plate 10 and the clamping slot 12 just form a tight clamping relationship, thereby realizing the rapid assembly of the male connector 1 and the female connector 5, and then realizing the rapid replacement of internal components.

[0042] When the threaded sleeve 13 is tightened, the inner wall of the sealing groove 17 opened inside the threaded sleeve 13 and the inner wall of the sealing groove 17 opened inside the male joint 1 and the female joint 5 will compress the sealing ring 16, thereby sealing and protecting the joints between the threaded sleeve 13 and the male joint 1, and the threaded sleeve 13 and the female joint 5. When the female joint 5 is completely connected to the male joint 1, the outer wall of the female joint 5 will compress the gasket 18 to prevent water seepage at the joint between the female joint 5 and the male joint 1. At the same time, the multiple sealing rings 19 arranged on the outside of the female joint 5 will enter the corresponding grooves 20 for reset, so that the sealing rings 19 are engaged in the grooves 20. This design of multiple sealing structure further improves the sealing performance of the joint between the male joint 1 and the female joint 5.

[0043] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
