Description

Technical Field

[0001] This utility model belongs to the field of plug technology, specifically relating to a stable plug for connecting photovoltaic panels and output lines. Background Technology

[0002] The output lines of a photovoltaic (PV) panel are one of the core components of a solar power generation system. Their main function is to transmit the electrical energy generated by the PV panel to energy storage devices or grid-connected inverters. PV panel output lines typically consist of two parallel conductors, usually black or dark-colored for better UV protection. The conductors are typically wrapped with an insulating material, such as PVC or XLPE, to ensure safety and prevent energy leakage. The conductors are generally made of high-purity copper or aluminum to ensure good conductivity and corrosion resistance. The insulation layer uses high-temperature and aging-resistant materials to withstand the complex and changing outdoor environment.

[0003] The connection between photovoltaic panels and output lines is generally achieved using male and female plugs. While existing male and female plugs offer waterproofing and quick-connect fixation, the output lines are typically located below the photovoltaic panels, which are usually installed on rooftops or hillsides. Natural winds can easily cause the output lines to sway. Additionally, birds may perch under the photovoltaic panels due to weather or other factors, pulling down on the output lines and consequently straining the plugs. This can create gaps at the connection point, allowing rainwater to seep in and weakening the connection strength, thus reducing the plug's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a stable plug for connecting photovoltaic panels and output lines, which can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a stable plug for connecting a photovoltaic panel to an output line, including a female stable sleeve, a male stable sleeve, and a plug-in fastening assembly. Both the female and male stable sleeves are provided with a tightening and sealing assembly. The tightening and sealing assembly includes two compression sealing plugs, a push spring, and a tightening nut. The two compression sealing plugs are symmetrically tapered and each has a through-hole for threading a wire. One compression sealing plug is movably fitted inside the female or male stable sleeve, and the other compression sealing plug is movably fitted inside the tightening nut. The push spring is located inside the female or male stable sleeve and on opposite sides of the two compression sealing plugs. A female head connection thread is formed on one side of the outer wall of the female stable sleeve, and a male head connection thread is formed on one side of the outer wall of the male stable sleeve. The inner wall of the tightening nut engages with the male or female head connection thread through a formed spiral pattern.

[0007] The insertion fastening assembly includes an inner slip ring, a female head stabilizing tube, a tension thread, a male head stabilizing tube, and a tension nut. The female head stabilizing tube is connected to the other side of the female head stabilizing sleeve. The inner slip ring is located on the female head stabilizing tube near the female head stabilizing sleeve. A female head connector sleeve is movably fitted onto the female head stabilizing tube. The male head stabilizing tube is located on the other side of the male head stabilizing tube. A male head connector terminal is movably fitted inside the male head stabilizing tube. The male head connector terminal is inserted into and engaged with the female head connector sleeve. The male head stabilizing tube is inserted into and engaged with the female head stabilizing tube.

[0008] Using the aforementioned stable plug for connecting photovoltaic panels and output lines, the output line passes through a tightening nut, two compression sealing plugs, a push spring, and a female or male stabilizing sleeve. The output line is then connected to the male terminal block or female terminal block. The male terminal block is adjusted into the male stabilizing tube, and the female terminal block is adjusted into the female stabilizing tube. The tightening nut is then pushed to slide on the output line, causing it to connect with the female or male threaded connection. Simultaneously, the tightening nut compresses one of the compression sealing plugs against the push spring, causing the push spring to push the two compression sealing plugs away from each other. The compression sealing plug applies pressure to the output line, thereby fixing the output line. Then, the male terminal on the male retaining sleeve is inserted into the female retaining tube, so that the female retaining tube abuts against the insertion sealing ring. Then, the tension nut is moved to connect the internal thread ring with the tension thread. Then, the tension nut is rotated, causing the tension nut to rotate and move the female retaining sleeve closer to the male retaining sleeve, thereby causing the male terminal and the male retaining tube to be inserted into the female retaining tube. At the same time, the compression sealing ring is formed to create a compression sealing effect. This can fix the male and female retaining sleeves after insertion, thereby improving tensile strength and extending their service life.

[0009] Preferably, the tensioning thread is located on the other side of the outer wall of the female retaining sleeve, and an internal threaded ring is fixedly provided on one side of the inner wall of the tensioning thread. The internal threaded ring is threadedly engaged with the tensioning thread. A limit ring is slidably installed on the outer wall of the inner sleeve slip ring. The limit ring is fixedly installed on the other side of the inner wall of the tensioning nut. A blocking ring is slidably provided inside the tensioning nut. The blocking ring is fixedly provided on one side of the outer wall of the inner sleeve slip ring to prevent the limit ring from sliding off the inner sleeve slip ring.

[0010] Preferably, a plug-in sealing ring is slidably fitted on the male head stabilizing tube, the inner diameter of the plug-in sealing ring being smaller than the outer diameter of the female head stabilizing tube, and the outer diameter of the plug-in sealing ring being smaller than the outer diameter of the blocking ring.

[0011] Preferably, the side of the tightening nut has a through hole for inserting the tapered constricted end of the compression sealing plug. After the compression sealing plug is inserted into the hole and contacts the wall, the length of its tapered constricted end protruding outside the tightening nut is one-third of the total length of the compression sealing plug.

[0012] Preferably, both the female and male stabilizing sleeves have tapered shrinkage holes on their inner walls, and the tapered shrinkage holes are inserted into and fitted with the tapered shrinkage end of the compression sealing plug.

[0013] Preferably, the inner diameters of both the female and male stabilizing tubes are consistent with the inner diameter of the tapered contraction end of the tapered contraction hole.

[0014] The beneficial effects are:

[0015] 1. This utility model uses the compression sealing plug, push spring and compression nut on the top-tightening sealing assembly to compress the push spring after the compression nut is threadedly connected to the female or male retaining sleeve. This push spring pushes the two compression sealing plugs away from each other, thereby applying compression force to the output line. This can form a double compression on the output line, improving the tensile strength and waterproof performance after the output line is fixed.

[0016] 2. This utility model, through the plug-in fastening component and the plug-in sealing ring, enables the plug-in fastening component to improve the connection strength of the male and female stable sleeves after the male and female stable sleeve plugs are plugged in by using the tightening nut. At the same time, it squeezes the plug-in sealing ring to improve the fixing effect after the plug is plugged in and extend the service life of the plug. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a stable plug for connecting a photovoltaic panel to an output line includes a female stable sleeve 1, a male stable sleeve 2, and a plug-in fastening assembly. Both the female stable sleeve 1 and the male stable sleeve 2 are provided with a tightening sealing assembly. The tightening sealing assembly includes two compression sealing plugs 3, a push spring 4, and a tightening nut 5. The two compression sealing plugs 3 are symmetrically tapered and each has a through hole for threading wires. One compression sealing plug 3 is movably fitted inside the female stable sleeve 1 or the male stable sleeve 2, and the other compression sealing plug 3 is movably fitted inside the tightening nut 5. The push spring 4 is located inside the female stable sleeve 1 or the male stable sleeve 2 and is located on opposite sides of the two compression sealing plugs 3. A female head connection thread 1d is formed on one side of the outer wall of the female stable sleeve 1, and a male head connection thread 2c is formed on one side of the outer wall of the male stable sleeve 2. The inner wall of the tightening nut 5 is threadedly engaged with the male head connection thread 2c or the female head connection thread 1d through a formed spiral pattern.

[0026] The plug-in fastening assembly includes an inner slip ring 1a, a female head stabilizing tube 1c, a tension thread 2a, a male head stabilizing tube 2b, and a tension nut 9. The female head stabilizing tube 1c is connected to the other side of the female head stabilizing sleeve 1. The inner slip ring 1a is located on the female head stabilizing tube 1c near the female head stabilizing sleeve 1. The female head stabilizing tube 1c is movably fitted with a female head wiring sleeve 7. The male head stabilizing tube 2b is located on the other side of the male head stabilizing tube 2b. The male head wiring terminal 6 is movably fitted inside the male head stabilizing tube 2b. The male head wiring terminal 6 is plugged into the female head wiring sleeve 7, and the male head stabilizing tube 2b is plugged into the female head stabilizing tube 1c.

[0027] As an optional implementation, the tensioning thread 2a is provided on the other side of the outer wall of the female retaining sleeve 1, and an internal threaded ring 9b is fixedly provided on one side of the inner wall of the tensioning thread 2a. The internal threaded ring 9b is threadedly engaged with the tensioning thread 2a. A limit ring 9a is slidably installed on the outer wall of the inner sleeve slip ring 1a. The limit ring 9a is fixedly installed on the other side of the inner wall of the tensioning nut 9. A blocking ring 1b is slidably provided inside the tensioning nut 9. The blocking ring 1b is fixedly provided on one side of the outer wall of the inner sleeve slip ring 1a to prevent the limit ring 9a from sliding off the inner sleeve slip ring 1a. This arrangement allows the tensioning nut 9 to tighten and fix the female retaining sleeve 1 and the male retaining sleeve 2, thereby improving the fixing effect after the female retaining sleeve 1 and the male retaining sleeve 2 are connected.

[0028] See attached document Figure 2 Appendix Figure 3 and attached Figure 4 The male head stabilizing tube 2b is slidably fitted with an insertion sealing ring 8. The inner diameter of the insertion sealing ring 8 is smaller than the outer diameter of the female head stabilizing tube 1c, and the outer diameter of the insertion sealing ring 8 is smaller than the outer diameter of the blocking ring 1b. This arrangement allows the female head stabilizing tube 1c to squeeze the insertion sealing ring 8 after the male head stabilizing tube 2b is inserted into the female head stabilizing tube 1c, thereby forming a sealing effect between the male head stabilizing tube 2b and the female head stabilizing tube 1c.

[0029] Furthermore, a circular hole is provided through the side of the tightening nut 5 for inserting the tapered contraction end of the compression sealing plug 3. After the compression sealing plug 3 is inserted into the circular hole and contacts the wall, the length of its tapered contraction end protruding outside the tightening nut 5 is one-third of the total length of the compression sealing plug 3. This setting allows the compression sealing plug 3 to form a compression sealing effect on the output line or circular hole under the compression of the tightening nut 5, thereby improving the sealing effect after the tightening nut 5 is installed.

[0030] Furthermore, both the inner walls of the female stabilizing sleeve 1 and the male stabilizing sleeve 2 are provided with tapered shrinkage holes, and the tapered shrinkage holes are inserted into the tapered shrinkage end of the compression sealing plug 3. This arrangement allows the compression sealing plug 3 to compress the tapered shrinkage holes when under force, thereby applying compressive force to the output line and forming a secondary sealing effect after the female stabilizing sleeve 1 or the male stabilizing sleeve 2 is fixed to the output line.

[0031] Furthermore, the inner diameters of both the female connector retaining tube 1c and the male connector retaining tube 2b are consistent with the inner diameter of the tapered contraction end of the tapered contraction hole. This arrangement facilitates the passing of the output line through the female connector retaining tube 1c or the male connector retaining tube 2b, thereby improving the ease of installation.

[0032] Using the above structure, the output line passes through the tightening nut 5, two compression sealing plugs 3, a push spring 4, and a female stabilizing sleeve 1 or a male stabilizing sleeve 2. The output line is then connected to the male terminal block 6 or the female terminal sleeve 7. The male terminal block 6 is then adjusted into the male stabilizing tube 2b, and the female terminal sleeve 7 is adjusted into the female stabilizing tube 1c. The tightening nut 5 is then pushed to slide on the output line, causing it to connect with the female thread 1d or the male thread 2c. Simultaneously, the tightening nut 5 causes one of the compression sealing plugs 3 to compress the push spring 4, causing the push spring 4 to push the two compression sealing plugs 3 away from each other, thus causing the compression sealing plugs 3 to be subjected to force... Applying pressure to the output line to fix it, then inserting the male terminal 6 on the male retaining sleeve 2 into the female retaining tube 1c, so that the female retaining tube 1c abuts against the insertion sealing ring 8. Then, moving the tension nut 9 so that the internal thread ring 9b is threadedly connected to the tension thread 2a, and then rotating the tension nut 9, causing the tension nut 9 to rotate and drive the female retaining sleeve 1 to move closer to the male retaining sleeve 2, thereby driving the male terminal 6 and the male retaining tube 2b to be inserted into the female retaining tube 1c. At the same time, the insertion sealing ring 8 is squeezed to form a compression sealing effect. In this way, the male retaining sleeve 2 and the female retaining sleeve 1 are in a fixed position after insertion, thereby improving tensile strength and extending their service life.
