[0001] This utility model relates to the field of photovoltaic cable technology, specifically a photovoltaic cable connection structure. Background Technology

[0002] Photovoltaic cables are specialized cables used to connect photovoltaic modules (solar panels) to inverters and power distribution systems. They play a crucial role in photovoltaic systems, ensuring power transmission and reliable system operation. Photovoltaic cables need to have good weather resistance.

[0003] Existing photovoltaic cable connectors have poor tensile strength after connecting two optical cables. When the photovoltaic cable is stretched, the connection is prone to loosening and falling off, which affects the normal operation of the photovoltaic cable and makes it inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a photovoltaic cable connection structure to solve the problem mentioned in the background art: the existing photovoltaic cable connectors have poor tensile strength after connecting two optical cables, and when the photovoltaic cables are stretched, the connection is prone to loosening and falling off, thus affecting the normal operation of the photovoltaic cables and causing inconvenience in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic cable connection structure, including an optical cable one, an optical cable interface one fixedly connected to the right end of the optical cable one, a connecting bracket fixedly connected to the left end of the optical cable interface one, a rotating shaft rotatably connected to the front and rear sides of the connecting bracket, a threaded rod fixedly connected to the right end of the rotating shaft, a hand-tightening nut threadedly connected to the right side of the threaded rod, protective rods fixedly connected to the upper and lower sides of the connecting bracket, an optical cable interface two provided at the right end of the optical cable interface one, an optical cable two fixedly connected to the right end of the optical cable interface two, a mounting base fixedly connected to the right end of the optical cable interface two, mounting grooves provided on the front and rear sides of the mounting base, and mounting holes provided on the upper and lower sides of the connecting base.

[0006] Preferably, the positions of the two guard rods correspond to the positions of the two mounting holes, and the two mounting holes are located on the right side of the two guard rods.

[0007] Preferably, the diameter of the protective rod is the same as the inner wall diameter of the mounting hole, and the right end of the protective rod extends into the interior of the mounting hole and fits tightly against the inner wall of the mounting hole.

[0008] By using the above technical solution, and by setting up protective rods and mounting holes, the optical cable interface one and optical cable interface two can be aligned and connected by inserting the protective rod into the mounting hole. At the same time, the threaded rod and the mounting groove can be aligned with each other, thus facilitating quick positioning and installation by the user.

[0009] Preferably, there are two threaded rods, which are respectively distributed at the right ends of the two rotating shafts, and the right side surfaces of the two threaded rods are threaded with hand-tightening nuts.

[0010] Preferably, the positions of the two mounting slots correspond to the positions of the two threaded rods, and the width of the two mounting slots is greater than the diameter of the two threaded rods, and the two threaded rods are located inside the mounting slots.

[0011] By adopting the above technical solution, an installation groove and threaded rod are used in conjunction with a hand-tightening nut. The threaded rod is rotated into the installation groove by rotating the shaft, and the hand-tightening nut is rotated to make it fit tightly against the right wall of the mounting base, thereby locking the positions of optical cable interface one and optical cable interface two. This prevents the connection from loosening and falling off when the photovoltaic cable is stretched, and makes it convenient to use.

By rotating the shaft, the threaded rod is rotated into the installation groove, and by rotating the hand-tightening nut, it is made to fit tightly against the right wall of the mounting base, thereby locking the positions of optical cable interface one and optical cable interface two. This prevents the connection from loosening and falling off when the photovoltaic cable is stretched, making it convenient to use.

[0015] 2. This photovoltaic cable connection structure, through the use of protective rods and mounting holes, allows for the alignment and connection of optical cable interface one and optical cable interface two by inserting the protective rod into the mounting hole. It also aligns the threaded rod and the mounting groove, thus facilitating quick positioning and installation for users. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Referring to Figures 1-3, a photovoltaic cable connection structure includes an optical cable 1, an optical cable interface 2 fixedly connected to the right end of the optical cable 1, a connecting bracket 3 fixedly connected to the left end of the optical cable interface 2, a rotating shaft 4 rotatably connected to the front and rear sides of the connecting bracket 3, and two threaded rods 5 fixedly connected to the right end of the rotating shaft 4. The two threaded rods 5 are distributed on the right ends of the two rotating shafts 4, and each of the two threaded rods 5 has a hand-tightening nut 7 threadedly connected to its right side surface. Protective rods 6 are fixedly connected to the upper and lower sides of the connecting bracket 3. Optical cable interface 2 9 is provided at the right end of the connector 2. Optical cable 2 8 is fixedly connected to the right end of optical cable interface 2 9. Mounting base 10 is fixedly connected to the right end of optical cable interface 2 9. The shape of the connecting bracket 3 is the same as that of the mounting base 10. Mounting slots 11 are provided on the front and rear sides of the mounting base 10. The positions of the two mounting slots 11 correspond to the positions of the two threaded rods 5. The width of the two mounting slots 11 is greater than the diameter of the two threaded rods 5. The two threaded rods 5 are located inside the mounting slots 11. Mounting holes 12 are provided on the upper and lower sides of the connector.

[0024] Working principle: In use, the operator first inserts the protective rod 6 into the mounting hole 12 to align and connect the optical cable interface 1 2 and the optical cable interface 2 9. After the optical cable interface 1 2 and the optical cable interface 2 9 are connected, the operator rotates the shaft 4 to rotate the threaded rod 5 into the mounting groove 11. At this time, the operator rotates the hand-tightened nut 7 to make it fit tightly against the right wall of the mounting base 10, thereby fixing the position of the connecting bracket 3 and the mounting base 10. Fixing the connecting bracket 3 and the mounting base 10 locks the position of the optical cable interface 1 2 and the optical cable interface 2 9, preventing the connection from loosening and falling off when the photovoltaic cable is stretched, thus preventing the normal operation of the photovoltaic cable and facilitating the operator's use.

[0025] Compared with related technologies, the photovoltaic cable connection structure provided by this utility model has the following advantages: by setting the installation groove 11, threaded rod 5 and other components in conjunction with the hand-tightening nut 7, the threaded rod 5 is rotated into the installation groove 11 by rotating the shaft 4, and the hand-tightening nut 7 is rotated to make it fit tightly against the right wall of the mounting base 10, thereby locking the positions of the optical cable interface 1 2 and the optical cable interface 2 9, avoiding the problem of loosening and falling off the connection when the photovoltaic cable is stretched, and making it convenient to use.

[0026] Example 2:

[0027] Referring to Figures 1-4, the right end of optical cable 1 is fixedly connected to optical cable interface 2, the left end of optical cable interface 2 is fixedly connected to a connecting bracket 3, and the upper and lower sides of the connecting bracket 3 are fixedly connected to protective rods 6. The right end of optical cable interface 12 is provided with optical cable interface 2 9, the right end of optical cable interface 2 9 is fixedly connected to optical cable 2 8, and the right end of optical cable interface 2 9 is fixedly connected to a mounting base 10. The mounting base 10 has mounting grooves 11 on its front and rear sides, and mounting holes 12 on its upper and lower sides. The positions of the two protective rods 6 correspond to the positions of the two mounting holes 12, and the two mounting holes 12 are located on the right side of the two protective rods 6. The diameter of the protective rods 6 is the same as the inner diameter of the mounting holes 12, and the right end of the protective rods 6 extends into the interior of the mounting holes 12 and fits tightly against the inner wall of the mounting holes 12.

[0028] Working principle: When in use, the operator first inserts the protective rod 6 into the mounting hole 12, which aligns and connects the optical cable interface 1 2 and the optical cable interface 2 9. After the optical cable interface 1 2 and the optical cable interface 2 9 are connected, the connecting bracket 3 and the mounting base 10 will also align with each other, thereby aligning the threaded rod 5 and the mounting groove 11, which facilitates quick positioning and installation by the user.

[0029] Compared with related technologies, the photovoltaic cable connection structure provided by this utility model has the following beneficial effects: by setting up protective rods 6 and mounting holes 12, the optical cable interface 12 and optical cable interface 29 can be aligned and connected by inserting the protective rod 6 into the mounting hole 12. At the same time, the threaded rod 5 and the mounting groove 11 can be aligned with each other, thereby facilitating quick positioning and installation by the user.
