[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a safety protection device for photovoltaic panel connection line joints, including:

[0028] First connector 1 and second connector 2; First connector 1 and second connector 2 are connected to each other by a connecting assembly, and first connector 1 and second connector 2 are also fixedly connected by a fastening assembly.

[0029] The first connector 1 includes a first body 13; the second connector 2 includes a second body 22; two symmetrically arranged adjustment grooves 3 are provided on the end face of the first body 13, and a sliding groove 31 is provided extending downward from the bottom of the adjustment groove 3.

[0030] The second main body 22 has a slot 4 on its end face, and the fastening component is inserted into the slot 4 to fix the first connector 1 and the second connector 2 into place.

[0031] The first connector 1 also includes a first cable 11 and a flexible sleeve 12; a fixing block 14 is fixedly installed on one side end face of the first body 13, and one end of the fixing block 14 is fixedly connected to the first cable 11; a connecting end 15 is installed on the other end of the fixing block 14; a flexible sleeve 12 is fixedly installed on the other end face of the first body 1, and the first cable 11 extends into the flexible sleeve 12 and is electrically connected to the fixing block 14.

[0032] The second body 22 also includes a second cable 21 and a flexible sleeve 12; a wiring groove 23 is provided on one end face of the second body 22; a plug-in port 24 is provided in the wiring groove 23, and the plug-in port 24 is electrically connected to the second cable 21 that extends into the flexible sleeve 12; the connection end 15 is plugged into and fixed to the plug-in port 24.

[0033] The fastening assembly includes a plug plate 33, one end of which is fixedly mounted with a slider 32, and the other end of the plug plate 33 extends out of the adjustment groove 3 and has a snap-fit ​​protrusion 34 on the side facing the fixing block 14; one side of the plug plate 33 is connected to the inner wall of the adjustment groove 3 by a spring 35; a connecting rod 36 is fixedly mounted on the other side of the plug plate 33, the connecting rod 36 passes through the outer wall of the first main body 13 and is fixedly mounted with a pull ring 37;

[0034] The slot 4 has a square cavity structure. A buffer hole 41 and a limiting hole 42 are provided on the side of the slot 4 facing the wiring slot 23. The limiting hole 42 is located at the bottom of the slot 4, and the distance between the buffer hole 41 and the limiting hole 42 is 2-3mm.

[0035] The plug plate 33 extends into the slot 4 and the snap-fit ​​protrusion 34 at its end is placed in the buffer hole 41 or the limiting hole 42.

[0036] The connecting assembly includes a protective sleeve 5, a plug 6, and a connecting plate 16 fixedly mounted on the first body 13; there are two connecting plates 16, which are respectively located at the top and bottom of the fixing block 14; the connecting plate 16 is also provided with a connecting hole 17.

[0037] The second body 22 is provided with a connecting groove 25 that is structurally adapted to the position of the connecting plate 16; a through hole corresponding to the position of the connecting hole 17 is also provided between the connecting groove 25 and the second body 22, and the through hole penetrates the outer wall of the second body 22.

[0038] The insert 6 passes through the connecting hole 17 through the through hole, so that the connecting plate 16 is limited and installed in the connecting groove 25; the protective sleeve 5 is sleeved on the outer wall of the second body 22, and a sleeve hole for the insert 6 to pass through is formed on the protective sleeve 5.

[0039] In one embodiment of this utility model, when it is necessary to connect two photovoltaic cables, the first cable 11 and the second cable 21 are respectively installed in two flexible sleeves 12 and pressed onto the fixing block 14 in the first body 13 and the insertion port 24 in the second body 22; when the first connector 1 and the second connector 2 are connected, the connecting end 15 is inserted into the insertion port 24; at the same time, the two connecting plates 16 are inserted into the connecting groove 25; after the connecting hole on the connecting plate 16 corresponds to the through hole, the protective sleeve 5 is put on the second body 22, and the insertion post 6 passes through the protective sleeve 5 and the through hole and is placed in the connecting hole 17; so that the first body 13 and the second body 22 are connected and secured.

[0040] In one embodiment of the present invention, when two photovoltaic cables are connected, the plug plate 33 on the first body 13 enters the second body 22 along the slot 4; the end of the plug plate 33 is flush with the side wall of the slot 4, and the snap-fit ​​protrusion 34 formed thereon cannot directly insert the plug plate 33 into the slot when the first body 13 and the second body 22 are connected, which will result in a limit.

[0041] Furthermore, since the snap-fit ​​protrusion 34 needs to be snapped into the buffer hole 41 or the limiting hole 42 before the first main body 13 and the second main body 22 can be laterally fixed; at this time, by pulling the pull ring 37, the plug plate 33 is pulled through the connecting rod 36, so that the slider 32 slides in the slide groove 31 to achieve horizontal displacement, thereby raising the snap-fit ​​protrusion 34 to the bottom of the slot 4 to complete the insertion.

[0042] Furthermore, the purpose of setting the buffer hole 41 or the limiting hole 42 is to adapt to different plug-in plate 33 lengths. When connecting photovoltaic cables, the length of the plug-in port 24 and the connection end 15 may be adjusted due to the output power. Therefore, the length of the plug-in plate 33 that is adapted to it also needs to be adjusted, so it can be adapted to more models.

[0043] Furthermore, the buffer hole 41 can also be used to prevent the snap-fit ​​protrusion 34 from shifting from the limiting hole 42 into the buffer hole 41 when the first body 13 and the second body 2 are misaligned and disengaged under external force, so that it will not break directly from the plug plate 33 due to the strong shear force and friction.

[0044] In one embodiment of this utility model, due to the limitation of the slider 32 in the groove 31, the plug plate 33 cannot be lifted out of position and can only move horizontally.

[0045] In one embodiment of this utility model, when the plug plate 33 is plugged in by pulling, it is to prevent the protective device from being accidentally squeezed by external force during daily use, which may cause the first body 13 and the second body 22 to detach.

[0046] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
