[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figure 1 This is the first embodiment of the present invention, which provides a photovoltaic connector crimping mechanism, including a crimping assembly 1. The crimping assembly 1 includes a lower crimping plate 11 and an upper crimping plate 12 movably disposed on the lower crimping plate 11. The lower crimping plate 11 and the upper crimping plate 12 work together to achieve stable and rapid clamping of the photovoltaic connector.

[0030] The sealing assembly 2 includes a sealing strip 21 disposed on the near end faces of the lower clamping plate 11 and the upper clamping plate 12, a conductive sheet 22 disposed on the sealing strip 21, and a sealing half-ring 23 disposed on the sealing strip 21. The cooperation of the sealing strip 21 and the sealing half-ring 23 can stably clamp the photovoltaic connector and fill the gap between the photovoltaic connector and the lower and upper clamping plates 11 and 12, thereby isolating the connection between the two photovoltaic connectors from air, preventing impurities from entering, and reducing the possibility of arcing. Simultaneously, the lower and upper clamping plates 11 and 12 as a whole clamp the photovoltaic connector, preventing it from being too loose or too tight.

[0031] During use: Place the two photovoltaic connectors on the sealing assembly 2 from two directions, with the peeled ends of the two photovoltaic connectors overlapping on the conductive sheet 22. Then, by pressing the lower plate 11 and the upper plate 12 together, the two photovoltaic connectors can be quickly pressed together. The sealing strip 21 and the sealing half-ring 23 press the outer circumference of the two photovoltaic connectors, which avoids the photovoltaic connectors being pressed too loosely or too tightly, and prevents air and impurities from entering the conductive sheet 22 and contacting the peeled ends of the two photovoltaic connectors, thus preventing arcing.

[0032] Example 2

[0033] Reference Figure 1This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that by setting the clamping groove 212 and the through groove 213, the photovoltaic connector can be tightly wrapped, thus avoiding damage to the photovoltaic connector.

[0034] Preferably, both the lower pressing plate 11 and the upper pressing plate 12 have through grooves 13 on their adjacent end faces. The two through grooves 13 are arranged coaxially. There are two sets of sealing components 2, and the two sets of sealing components 2 are respectively installed in the two through grooves 13. The projected shape of the side of each through groove 13 is semi-circular. When the lower pressing plate 11 and the upper pressing plate 12 are pressed together, the two through grooves 13 cooperate to form a cylindrical groove for installing the two sets of sealing components 2.

[0035] Furthermore, a sealing strip 21 is disposed within the through groove 13. One end of the sealing strip 21 has a groove 211, and the other end has a pressing groove 212. A connecting groove 213 is provided on the sealing strip 21, which is inclined and connects the groove 211 and the pressing groove 212 at its two ends respectively. The sealing half-ring 23 of one set of sealing components 2 cooperates with the pressing groove 212 of another set of sealing components 2 to stably press the photovoltaic connector. The connection points of the two photovoltaic connectors are located at the conductive sheet 22, i.e., within the groove 211. The larger diameter groove 211 accommodates the connection points of the two photovoltaic connectors, while the entry end of the photovoltaic connector is pressed within the smaller diameter pressing groove 212, achieving a tight fit and protecting the photovoltaic connector.

[0036] Furthermore, the sealing strip 21 is provided with a sealing groove 214, which communicates with the pressing groove 212 and the connecting groove 213. The sealing half-ring 23 is provided with a flange 231 that cooperates with and presses against the sealing groove 214. The connecting groove 213 provides a transition for the bent photovoltaic connector, avoiding direct twisting and pressing of the photovoltaic connector, thus protecting it. At the same time, the cooperation between the flange 231 and the sealing groove 214 leaves space for pressing the photovoltaic connector, preventing over-pressing or under-pressing of the photovoltaic connector.

[0037] In particular, the conductive sheet 22 is installed in the groove 211, and a fixing groove 215 for fixing the photovoltaic connector is provided between the conductive sheet 22 and the connecting groove 213. The conductive sheet 22 is used to press and conduct electricity to the photovoltaic connector with the outer sheath removed, and the fixing groove 215 is used to place the photovoltaic connector that extends beyond the conductive sheet 22. This makes it easy to accommodate the photovoltaic connector with the outer sheath removed, facilitates the installation of the photovoltaic connector, and improves the convenience of installation.

[0038] It is worth mentioning that the sealing strip 21 is made of insulating material. By using insulating material, the overall safety of the device can be improved.

[0039] During use: The connecting groove 213 provides a transition for the bent photovoltaic connector, avoiding direct twisting and tightening of the photovoltaic connector, thus protecting it. At the same time, the cooperation between the flange 231 and the sealing groove 214 leaves space between them to compress the photovoltaic connector, preventing excessive or insufficient compression. The use of insulating materials improves the overall safety of the device.

[0040] Example 3

[0041] Reference Figure 2 - Figure 4 This is the third embodiment of the present invention. This embodiment further provides an arc-extinguishing crimping device, including the photovoltaic connector crimping mechanism in the above embodiment, and also includes a locking component 3. The locking component 3 includes a lower locking part 31 disposed on the lower pressing plate 11 and a higher locking part 32 disposed on the upper pressing plate 12. The upper locking part 32 cooperates with the lower locking part 31 to lock. The lower locking part 31 and the upper locking part 32 achieve stable locking of the lower pressing plate 11 and the upper pressing plate 12, thereby enabling stable crimping of the photovoltaic connector. The crimping of the photovoltaic connector will not be too loose or too tight. The lower pressing plate 11 and the upper pressing plate 12 eliminate air around the photovoltaic connector, preventing arcing when energized.

[0042] Preferably, the locking lower part 31 includes a fixing plate 311 disposed on the pressing lower plate 11, and an engaging lower plate 312 disposed on the fixing plate 311.

[0043] Furthermore, the lower engagement plate 312 is provided with multiple locking grooves 3121, and the lower engagement plate 312 is provided with relief grooves 3122 communicating with the multiple locking grooves 3121. Each locking groove 3121 has a locking slot 3123 on its inner wall, and each locking groove 3121 has a guide groove 3124 communicating with the locking slot 3123 on its inner wall. The depth of the guide groove 3124 is lower than the depth of the locking slot 3123, thus enabling stable locking of the upper locking part 32. The relief groove 3122 is located between the fixed plate 311 and the multiple locking grooves 3121, making it convenient for the user to move the lower locking part 31 and the upper locking part 32 apart through the relief groove 3122.

[0044] In particular, the upper locking part 32 includes a connecting plate 321 disposed on the upper pressing plate 12, a lower engaging plate 322 disposed on the connecting plate 321, and engaging teeth 323 disposed on the lower engaging plate 322. The engaging teeth 323 engage and extend into the locking groove 3121, and the engaging teeth 323 are provided with locking blocks 3231. By engaging multiple engaging teeth 323 into multiple locking grooves 3121, a stable locking of the upper locking part 32 and the lower locking part 31 can be achieved, avoiding unstable pressing of the photovoltaic connector. Furthermore, the lower pressing plate 11 and the upper pressing plate 12 can be separated by moving the connecting plate 321 and the fixing plate 311 away from each other, facilitating the replacement of the photovoltaic connector and avoiding disassembly with other tools, thus improving the convenience of operation.

[0045] During use: The locking lower part 31 and locking upper part 32 achieve stable locking of the pressing lower plate 11 and pressing upper plate 12, thereby stably pressing the photovoltaic connector. The pressing of the photovoltaic connector will not be too loose or too tight. The pressing lower plate 11 and pressing upper plate 12 remove air around the photovoltaic connector, avoiding arcing when energized. The multiple meshing teeth 323 engage with multiple locking grooves 3121, thereby achieving stable locking of the locking upper part 32 and locking lower part 31, avoiding unstable pressing of the photovoltaic connector. The pressing lower plate 11 and pressing upper plate 12 can be separated by moving the connecting plate 321 and the fixing plate 311 away from each other, which facilitates the replacement of the photovoltaic connector and avoids disassembly with other tools, improving the convenience of operation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
