[0031] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of multiple components or the interaction relationship between multiple components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] This embodiment provides a photovoltaic power generation line connector fastening device, such as Figure 1-Figure 4 As shown, it includes an upper cover 10, a lower cover 20, two clamping members 30 and a clamping member driving mechanism 40;

[0034] The upper cover 10 is provided with a clamping member driving mechanism 40, and the clamping member driving mechanism 40 drives the two clamping members 30 to move toward each other to clamp the line connector;

[0035] The upper cover 10 is used to connect with the lower cover 20, so that the two clamping members 30 and the clamping member driving mechanism 40 are located between the upper cover 10 and the lower cover 20;

[0036] After the upper cover 10 and the lower cover 20 are connected, the fastening device includes at least two line ports 80 .

[0037] When in use, the line connector is placed in the lower cover 20, and the upper cover 10 is covered, and the line connector is ensured to be located between the two clamping members 30. The two clamping members 30 are driven by the clamping member driving mechanism 40 to clamp the line connector, that is, force is applied to both ends of the plug and the socket of the line connector; and the line connected to the plug and the line connected to the socket are respectively passed through the two line ports 80.

[0038] In some embodiments, Figure 1 , Figure 2 As shown, the clamping member driving mechanism 40 includes a rotating shaft 41, a driving gear 42, a transmission gear 43 and a ball screw 44;

[0039] The upper cover 10 is movably connected to the rotating shaft 41, and at least one end of the rotating shaft 41 is in communication with the outside of the upper cover 10;

[0040] The rotating shaft 41 is fixedly connected to the driving gear 42, the driving gear 42 is gear-engaged with the transmission gear 43, and the transmission gear 43 is fixedly connected to the ball screw 44;

[0041] The ball screw 44 is provided with a first thread 441 and a second thread 442 with opposite threads;

[0042] Two ends of the ball screw 44 are connected to the two clamping members 30 respectively through a first thread 441 and a second thread 442 .

[0043] Through this structure, the rotating shaft 41 can be rotated to drive the connecting clamping parts 30 to move toward each other, so that the clamping parts 30 clamp the line connector. This structure is simple and easy to operate and manufacture.

[0044] The rotating shaft 41 is connected to the outside of the upper cover 10, which is more conducive to driving the rotating shaft 41 to rotate. The rotating shaft 41 can be driven to rotate by directly rotating the rotating shaft 41, that is, the rotating shaft 41 has at least one end disposed outside the rotating shaft 41. Of course, this method is only one embodiment.

[0045] In some embodiments, the rotating shaft 41 is connected to a driving block 50, and the driving block 50 is disposed outside the upper cover 10, and the diameter of the rotating shaft 41 is smaller than the minimum radial length of the driving block 50. The radial direction in the radial length of the driving block 50 should be the same as the diameter direction of the rotating shaft 41, based on which the rotating shaft 41 can be rotated by the driving block 50, and since the diameter of the rotating shaft 41 is smaller than the minimum radial length of the driving block 50, it is more labor-saving when driving the rotating shaft 41 to rotate.

[0046] In some embodiments, the driving block 50 is provided with a slot 51. After the slot 51 is provided, a tool can be used to cooperate with the slot 51 to rotate the shaft 41, so that the size of the driving block 50 can be reduced, which not only saves costs, but also saves more effort to drive the shaft 41 through the slot 51.

[0047] In some embodiments, the two ends of the ball screw 44 are rotatably connected to the upper cover 10. Specifically, an annular boss is provided in the upper cover 10, and the two ends of the ball screw 44 are provided in the annular boss. Preferably, the inner diameter of the annular boss is adapted to the outer diameter of the two ends of the ball screw 44. This connection method is simple and can also ensure the rotation of the ball screw 44.

[0048] In some embodiments, Figure 1 , Figure 2 As shown, it also includes a guide rod 60, the extension direction of which is arranged parallel to the ball screw 44; the clamping member 30 is provided with a connecting hole, the guide rod 60 is arranged in the connecting hole, and both ends of the guide rod 60 are fixedly connected to the upper cover 10. Based on this, the guide rod 60 not only has a guiding function, but also has the advantage of labor saving.

[0049] In some embodiments, the clamping member 30 includes a clamping plate 31 and a slider 32 , the clamping plate 31 and the slider 32 are fixedly connected, and the slider 32 is connected to the clamping member driving mechanism 40 .

[0050] In some embodiments, Figure 1 As shown, a groove 311 is provided at the bottom of the clamping plate 31. Because the two ends of the line connector are connected to the line, if the groove 311 is not provided, the lines at both ends of the line connector can only pass through the bottom of the clamping plate 31, and the contact area between the clamping plate 31 and the line connector will be reduced. However, by providing the groove 311 at the bottom of the clamping plate 31, the line can pass through the groove 311, thereby increasing the contact area between the clamping plate 31 and the line connector, and having a better clamping effect on the line connector.

[0051] In some embodiments, Figure 3As shown, the upper cover 10 includes a cover body 11 and a drive chassis 12, the cover body 11 and the drive chassis 12 are fixedly connected, and the clamping member driving mechanism 40 is arranged in the drive chassis 12. Based on this, it has the advantages of reducing material usage and reducing costs.

[0052] In some embodiments, the upper cover 10 and the lower cover 20 are connected by a strong magnetic plate 70. Specifically, a strong magnetic plate 70 can be provided on the cover body 11, such as Figure 4 As shown, a strong magnetic plate 70 can also be provided on the lower cover 20. Based on this, the connection method is simpler. Of course, the upper cover 10 and the lower cover 20 can also be connected by bolts or the like.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
