Obviously, the described embodiments are only 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.

[0030] like Figures 1 to 7 As shown, the present invention provides an electrical connection mechanism for a building photovoltaic component, comprising a fixing seat 1 and two groups of electrical connectors 7 and connecting wires 8, the two electrical connectors 7 are plugged into each other, and the two connecting wires 8 are electrically connected to the electrical connectors 7 respectively, and also comprises: a limiting ring 2, the limiting ring 2 is provided with two groups, and the two groups of limiting rings 2 are respectively fixed to the two ends of the fixing seat 1; a transmission component 3, the transmission component 3 is arranged on the outside of the limiting ring 2; a protection component 5, the protection component 5 is rotatably connected to the limiting ring 2; a stabilizing component 4, the stabilizing component 4 is installed on the protection component 5, and the limiting ring 2, the transmission component 3 and the stabilizing component 4 are symmetrically arranged at the two ends of the protection component 5;

[0031] The transmission assembly 3 includes a gear 301, a rotating rod 302 and a slider 303. The middle of the gear 301 is fixedly connected to the rotating rod 302. The middle of the rotating rod 302 is rotatably connected to the protection assembly 5. The end of the rotating rod 302 away from the gear 301 is provided with a thread adapted to the slider 303.

[0032] The stabilizing component 4 includes a clamping plate 401, a hard spring 402, a top plate 403, a limit block 404 and a spring 405. The middle part of the clamping plate 401 is hinged on the protection component 5. The two ends of the hard spring 402 are respectively fixed to the clamping plate 401 and the slider 303. The two ends of the limit block 404 are both fixed to the protection component 5. A sliding groove adapted to the limit block 404 is provided on the top plate 403. The top of the top plate 403 abuts against the limit block 404. A plurality of springs 405 are provided. The two ends of the spring 405 are respectively fixed to the limit block 404 and the spring 405.

[0033] By inserting the docked electric connector 7 through the installation port of the protective shell 501, the electric connector 7 is located between the two clamping plates 401, and the protective shell 501 is pulled to rotate by the handle 502, the gear 301 can roll along the tooth of the limit ring 2, and the rotation of the rotating rod 302 causes the slider 303 to slide along the moving groove, and the slider 303 pulls the clamping plate 401 through the hard spring 402, so that the arc block can clamp the two electric connectors 7, and the support block 503 is driven to rotate by the protective shell 501, and the middle part of the support block 503 can be rotated to the oblique lower part of the electric connector 7, which can provide upward support for the electric connector 7, and the protective shell 501 covers the electric connector 7, which can reduce the direct impact of external force on the connection of the electric connector 7, so that the connection stability of the device is strong.

[0034] like Figure 1 and Figure 2 , Figure 6 and Figure 7 As shown, the protection assembly 5 includes a protection shell 501, a handle 502, a support block 503 and a connecting hole 504. Arc grooves for limiting the rotation of the limiting ring 2 are provided on both sides of the protection shell 501. The handle 502 is fixedly connected to the outer surface of the middle part of the protection shell 501. The support block 503 is fixedly connected to the middle part of the inner cavity of the protection shell 501. A plurality of connecting holes 504 are provided on the protection shell 501. A mounting port for installing the electric connector 7 is provided on the side of the protection shell 501 away from the handle 502. The support block 503 is a crescent-shaped structure, and the middle part of the support block 503 is in contact with the outer side of the electric connector 7.

[0035] The protective shell 501 is rotated by pulling the handle 502, and the protective shell 501 can be supported by the limit ring 2. The connecting hole 504 can facilitate the circulation of air and the dissipation of heat generated at the electrical connection. Since the support block 503 has a crescent-shaped structure that is thin on both sides and thick in the middle, and when the electric connector 7 is installed, the middle position of the support block 503 is located directly above the electric connector 7, it will not affect the installation of the electric connector 7. After the support block 503 rotates the protective shell 501, the middle position of the support block 503 can be rotated to the oblique lower part of the electric connector 7, so that the thicker middle part of the support block 503 can support the electric connector 7 upward, further improving the stability of the electric connector 7.

[0036] like Figure 1 and Figure 2 , Figure 5 As shown, both ends of the protective shell 501 are provided with a storage assembly 6, and the storage assembly 6 includes a fixed block 601, a winding rod 602 and a rotating block 603. The fixed block 601 is fixedly connected to both ends of the protective shell 501, and the middle ball shaft of the winding rod 602 is connected to the fixed block 601. The outer peripheral surface of the rotating block 603 is rotatably connected to the protective shell 501. A slot for rotating the winding rod 602 is provided on the rotating block 603. One end of the winding rod 602 located inside the protective assembly 5 is obliquely arranged on one side of the connecting line 8. A rubber layer is provided between the outer side of the rotating block 603 and the protective shell 501. A accommodating notch is provided on the fixed block 601, and the connecting line 8 is located in the accommodating notch.

[0037] When there is a connecting wire 8 remaining outside the protective shell 501, by twisting the rotating block 603, the rotating block 603 drives the winding rod 602 to rotate around the ball axis, and the winding rod 602 can wind the connecting wire 8 on the outer surface, so that the device is convenient for storing the connecting wire 8. By setting the accommodating groove, the connecting wire 8 and the electrical connector 7 can be installed together. After the protective shell 501 drives the fixing block 601 to rotate, the opening of the accommodating groove is tilted upward, which can support the connecting wire 8 upward.

[0038] like Figures 1 to 5 As shown, the limiting ring 2 is provided with arc-shaped arrays of latch teeth meshing with the gear 301, and the protective shell 501 is provided with a moving groove for limiting the horizontal sliding of the gear 301;

[0039] The bottom of the clamping plate 401 is an arc block, the outer side of the arc block abuts against the electric connector 7, the top of the top plate 403 is provided with an arc column head, the outer side of the arc column head abuts against the clamping plate 401, the spring 405 is provided in the slide groove of the top plate 403, and the bottom of the top plate 403 abuts against the connecting line 8;

[0040] By pulling the protective shell 501 to rotate through the handle 502, the gear 301 can roll along the locking teeth of the limiting ring 2, and the rotation of the rotating rod 302 allows the slider 303 to slide along the moving groove. The slider 303 pulls the clamping plate 401 through the hard spring 402, so that the arc block can clamp the two electrical connectors 7. It is worth mentioning that when the hard spring 402 is pulled by the slider 303, its elastic deformation becomes smaller and will not affect the clamping effect of the clamping plate 401.

[0041] The working principle and use process of the present invention:

[0042] First, the operator installs and fixes the fixing seat 1 with screws, and puts the docked electric connector 7 through the installation opening of the protective shell 501, so that the electric connector 7 is located between the two clamping plates 401. The protective shell 501 is pulled and rotated by the handle 502, and the gear 301 can roll along the teeth of the limit ring 2. The rotation of the rotating rod 302 causes the slider 303 to slide along the moving groove. The slider 303 pulls the clamping plate 401 through the hard spring 402, so that the arc block can clamp the two electric connectors 7. The support block 503 is driven to rotate through the protective shell 501, and the middle part of the support block 503 can be rotated to the oblique lower part of the electric connector 7.

[0043] By rotating the clamping plate 401, the top plate 403 can be pushed downward, and the top plate 403 can slide along the limit block 404. The spring 405 is stretched, so that the excess part of the other end of the connecting line 8 can be pushed by the top plate 403 to be bent and stored in the protective shell 501. If there is any connecting line 8 remaining outside the protective shell 501, by twisting the rotating block 603, the rotating block 603 drives the winding rod 602 to rotate around the ball axis, and the winding rod 602 can wind the connecting line 8 on the outer surface to complete the operation.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
