Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, in particular to an auxiliary fixing device for a photovoltaic connector. Background Art

[0002] Photovoltaic connectors are used to connect and extend photovoltaic cables. Their creepage distance and connection reliability are used as indicators to evaluate their quality. Photovoltaic connectors generally include female connectors and male connectors, which connect multiple solar cell modules into a system. They can also be said to be more formal wiring terminals, or quick connectors, which can be plugged in and out at any time.

[0003] At present, traditional photovoltaic connectors usually connect the sub-shell and the mother shell tightly together through a bayonet mechanism to ensure the stability and efficiency of power transmission; however, although this connection method shows good performance in the early stage, due to repeated plugging and unplugging actions, the contact surface between the bayonet and the shell will be constantly rubbed and squeezed; over time, the material on the surface of the buckle will gradually wear, forming tiny scratches or depressions; these wear phenomena will weaken the fixing force between the buckle and the shell; when the fixing effect is reduced, the stability of the photovoltaic connector will be challenged when it is affected by external environmental factors (such as wind force, temperature changes, etc.); this may cause the connection to loosen, thereby affecting the efficiency and safety of power transmission.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown, the utility model provides a photovoltaic connector auxiliary fixing device, including a female housing 1 and a sub-housing 2, a sealing sleeve 3 is fixedly installed on the surface of the female housing 1, a sealing groove 4 is provided at the front end of the sealing sleeve 3, a rotating ring 5 is rotatably connected to the surface of the sub-housing 2, an extrusion ring 6 located on the surface of the sub-housing 2 is fixedly installed at the rear end of the rotating ring 5, and limited holes 7 are provided on both sides of the surface of the extrusion ring 6;

[0024] A fixing mechanism is arranged on both sides of the surface of the sealing sleeve 3, and the fixing mechanism includes a square shell 8, which is fixedly connected to both sides of the surface of the sealing sleeve 3. The interior of the square shell 8 is rotatably connected to a rotating shaft 9, and the surface of the rotating shaft 9 is slidably connected to a moving plate 11. The opposite side of the moving plate 11 is elastically connected to a spring 10 located on the surface of the rotating shaft 9, and the other end of the spring 10 is fixedly connected to one side of the interior of the square shell 8. A fixing groove 12 is provided on the surface of the rotating shaft 9, and a protrusion 13 located inside the fixing groove 12 is fixedly installed inside the moving plate 11. A threaded rod 14 is fixedly installed on the opposite side of the rotating shaft 9, and the surface of the threaded rod 14 is threadedly connected to a limiting rod 15 located inside the limiting hole 7.

[0025] The above scheme is adopted: the operator inserts the sub-shell 2 into the interior of the mother shell 1, and then the extrusion ring 6 enters the interior of the sealing groove 4. Since the surface of the extrusion ring 6 contacts the inner wall of the sealing groove 4, the air inside the sealing groove 4 will be squeezed during the movement of the extrusion ring 6. Then the air will enter the interior of the delivery pipe 16, and then the air inside the delivery pipe 16 will enter the interior of the square shell 8. The air entering the interior of the square shell 8 will push the moving plate 11 to move. When the moving plate 11 moves, the spring 10 will be stretched, and the protrusion 13 will move inside the fixed groove 12. When the protrusion 13 moves, the rotating shaft 9 will rotate, and the rotating shaft 9 will drive the threaded rod 14 to rotate, and the rotating shaft 9 will rotate. The limiting rod 15 is threadedly connected with the threaded rod 14, and then the limiting rod 15 will move relatively, and then the surface of the limiting rod 15 will enter the interior of the limiting hole 7, and contact one side of the sealing sleeve 3 on one side of the rotating ring 5, and then the inner wall of the limiting hole 7 will contact the surface of the limiting rod 15, and then the rotating ring 5 can be rotated, and the extrusion ring 6 will rotate accordingly. Since the limiting hole 7 is an L-shaped design, when the extrusion ring 6 rotates, the limiting rod 15 and the limiting hole 7 will be misaligned, and then the limiting rod 15 will fix the extrusion ring 6, and finally enter the interior of the limiting hole 7 through the limiting rod 15, and rotate the extrusion ring 6 to increase the fixing effect of the mother shell 1 and the child shell 2.

[0026] like Figure 5 As shown, a circular groove 19 is provided on the surface of the sub-shell 2, a mounting groove 20 is provided inside the circular groove 19, a damping block 21 is provided inside the mounting groove 20, a damping ring 22 located inside the circular groove 19 is fixedly installed inside the rotating ring 5, the damping block 21 is spherical in design, and the surface of the damping block 21 is rough in design.

[0027] The above scheme is adopted: through the design of the damping block 21 and the damping ring 22, when the rotating ring 5 rotates, the damping ring 22 will rotate accordingly. Since the inner wall of the damping ring 22 contacts the surface of the damping block 21, the damping effect between the damping ring 22 and the damping ring 22 will be increased, thereby improving the rotation stability of the rotating ring 5; through the design of the damping block 21, since the surface of the damping block 21 is rough, the rough damping block 21 can increase the friction between the damping ring 22; this is because the rough surface has more uneven parts, which can provide a better "grip" effect to prevent the rotating ring 5 from sliding.

[0028] like Figure 1 and Figure 6 As shown, limiting grooves 17 are provided on both sides inside the square shell 8, and limiting rods 18 are slidably connected inside the limiting grooves 17. The opposite side of the limiting rods 18 is fixedly connected to the surface of the limiting rod 15, and a positioning block 24 is fixedly installed on the top of the surface of the sealing sleeve 3, and a positioning block 24 is fixedly installed on the top of the surface of the rotating ring 5.

[0029] The above scheme is adopted: through the design of the limit groove 17 and the limit rod 18, when the limit rod 15 moves, the limit rod 15 will drive the limit rod 2 18 to move, and then the limit rod 2 18 will move inside the limit groove 17. Since the size of the limit rod 2 18 is compatible with the size of the limit groove 17, the limit rod 15 can be limited. Through the limitation of the limit rod 15 by the limit rod 2 18, the limit rod 15 can be moved normally; through the design of the positioning block 1 23 and the positioning block 2 24, when the sub-shell 2 is inserted into the interior of the mother shell 1, one side of the positioning block 1 23 can be aligned with one side of the positioning block 2 24, and then the limit rod 15 and the limit hole 7 will be aligned. Finally, by setting the positioning block 1 23 and the positioning block 2 24, it is convenient for the limit rod 15 to enter the interior of the limit hole 7, thereby fixing the mother shell 1 and the sub-shell 2.

[0030] like Figure 4 As shown, the fixing groove 12 is designed to be inclined, the surface of the protrusion 13 fits the inner wall of the fixing groove 12, and a baffle is fixedly installed on one side of the surface of the rotating shaft 9, and the size of the baffle is larger than the size of the rotating shaft 9.

[0031] The above scheme is adopted: through the design of the fixed groove 12 and the protrusion 13, when the movable plate 11 moves, the protrusion 13 will slide inside the fixed groove 12. Due to the inclined design of the fixed groove 12 and the size of the protrusion 13 is compatible with the size of the fixed groove 12, it is convenient for the protrusion 13 to push the fixed groove 12 to rotate; through the design of the rotating shaft 9, when the movable plate 11 moves on the surface of the rotating shaft 9, the surface of the movable plate 11 will contact the surface of the baffle, thereby blocking the movement of the movable plate 11 and preventing the movable plate 11 from detaching from the surface of the rotating shaft 9.

[0032] The working principle and use process of this utility model:

[0033] First, the operator can align the positioning block 1 23 with one side of the positioning block 2 24, then insert the sub-shell 2 into the interior of the mother shell 1, and make the extrusion ring 6 enter the interior of the sealing groove 4. When the extrusion ring 6 moves inside the sealing groove 4, it will squeeze the air inside the sealing groove 4, and then the air will enter the interior of the square shell 8 through the conveying pipe 16, and then the air will push the movable plate 11 to move, and when the movable plate 11 moves, the spring 10 will be stretched, and the protrusion 13 will move inside the fixed groove 12, and then the rotating shaft 9 and the threaded rod 14 will rotate, and then through the limiting of the limiting rod 2 18, the limiting rod 1 15 will move relative to the surface of the threaded rod 14, and then the limiting rod 15 will enter the interior of the limiting hole 7, when one side of the rotating ring 5 contacts one side of the sealing sleeve 3, the rotating ring 5 can be rotated, and then the extrusion ring 6 and the limiting hole 7 will rotate accordingly, and then the limiting rod 15 and the limiting hole 7 will be misaligned, thereby fixing the mother shell 1 and the sub-shell 2, and finally completing the operation process.
