Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a quick-plug photovoltaic power generation equipment electrical connection component. Background Technology

[0002] Electrical connection components for photovoltaic power generation equipment are crucial for connecting core components such as photovoltaic modules and inverters. Existing technologies often suffer from problems such as high contact resistance, insufficient weather resistance, and cumbersome installation. With the large-scale development of photovoltaics, the demand for connection solutions with high reliability, low loss, and easy maintenance is becoming increasingly urgent.

[0003] In existing technologies, the MC4 photovoltaic connector plug section of the quick-plug photovoltaic power generation equipment is subject to a combination of factors, including external wind force, temperature changes, cable weight and tension, and equipment vibration. This can cause the plug section to become loose, resulting in poor contact. Additionally, cable swaying in the plug section can cause stress concentration and exacerbate the risk of loose connection, leading to cable swaying and affecting connection reliability.

[0004] To address this, a quick-pluggable electrical connection component for photovoltaic power generation equipment is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a quick-plug photovoltaic power generation equipment electrical connection component that can solve the problems of poor contact caused by loose plugging and the impact of cable swaying on connection reliability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-plug photovoltaic power generation equipment electrical connection assembly, including an MC4 photovoltaic connector, a cable fixedly connected to the rear side of the MC4 photovoltaic connector, a protective stabilizing mechanism provided on the outer side of the cable, a straightening and reinforcing component movably connected to the outer side of the protective stabilizing mechanism, the protective stabilizing mechanism including a protective box, the protective box being disposed on the outer side of the cable, a supporting slide rod slidably connected to the bottom of the protective box, supporting frames slidably connected to both sides of the top of the supporting slide rod, a fixed flexible rod fixedly connected to one side of each of the two supporting frames, a linkage slider fixedly connected to the bottom of the supporting frame, the linkage slider slidably connected to both sides of the bottom of the supporting slide rod, and a unidirectional fixing component slidably connected to the bottom of both the linkage slider and the supporting slide rod.

[0007] Preferably, the straightening and reinforcing component includes two fixing plates, which are fixedly connected to both sides of the protective box. The front and rear sides of the fixing plates are provided with positioning slots, and positioning blocks are inserted into the inner side of the positioning slots.

[0008] Preferably, an extension block is fixedly connected to each of the two linkage sliders on opposite sides, a guide slide rod is fixedly connected to the top of the extension block, and the positioning block is slidably connected to the outside of the guide slide rod.

[0009] Preferably, a compression spring is fixedly connected to the bottom of the outer side of the guide slide rod, and the compression spring is fixedly connected to the bottom of the positioning block.

[0010] Preferably, the co-directional fixing assembly includes an adjusting screw, which is movably connected to the bottom of the support slide rod. A support vertical rod is movably connected to the front side of the adjusting screw, and the support vertical rod is fixedly connected to the front side of the support slide rod. A threaded slider is slidably connected to the outer side of the support vertical rod, and the threaded slider is threadedly connected to the outer side of the adjusting screw.

[0011] Preferably, both sides of the threaded slider are rotatably connected to linkage rods, and the other ends of the two linkage rods are respectively rotatably connected to the bottom of the linkage slider.

[0012] Preferably, the protective box has a travel hole on its rear side.

[0013] Preferably, a positioning magnetic ring is fixedly connected to the front side of the protective box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a protective and stabilizing mechanism, can use a magnetically fixed protective box to cover the MC4 photovoltaic connector, which also serves to prevent impact, dust and water, reducing the direct impact of the external environment on the plug section. At the same time, by using the adjusting screw to drive the structure, the fixing soft rod fixes the plug section cable from both sides, limiting the swaying of the cable caused by wind, its own weight, vibration, etc., and avoiding stress concentration. Thus, it solves the problems of loose plugs, poor contact and unreliable connection caused by cable swaying caused by multiple factors.

[0016] 2. This application, by setting up a straightening and reinforcement component, can straighten the cable segment of the fixed cable structure during sliding by using the support slide rod in conjunction with the tightness control of the positioning plug. After it is in place, the support frame and the fixed soft rod both press the cable and abut against the back of the male connector to form a double anti-loosening effect, thereby further preventing the male connector from loosening. This solves the problems of insufficient cable straightening exacerbating the swaying, stress concentration and male connector loosening risks, and improves the reliability of the connection.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A quick-plug photovoltaic power generation equipment electrical connection assembly includes an MC4 photovoltaic connector 1. A cable 2 is fixedly connected to the rear side of the MC4 photovoltaic connector 1. A protective stabilizing mechanism 3 is provided on the outside of the cable 2. A straightening and reinforcing component 4 is movably connected to the outside of the protective stabilizing mechanism 3. The protective stabilizing mechanism 3 includes a protective box 31, which is located on the outside of the cable 2. A support slide rod 32 is slidably connected to the bottom of the protective box 31. Support frames 33 are slidably connected to both sides of the top of the support slide rod 32. Fixed flexible rods 34 are fixedly connected to the opposite sides of the two support frames 33. A linkage slider 35 is fixedly connected to the bottom of the support frame 33. The linkage slider 35 is slidably connected to both sides of the bottom of the support slide rod 32. A unidirectional fixing component 36 is slidably connected to the bottom of both the linkage slider 35 and the support slide rod 32.

[0026] In this embodiment: Before inserting the MC4 photovoltaic connector 1, the protective box 31 is fitted onto the outside of the cable 2 through the travel hole 5 on its rear side. After insertion, hold the protective box 31 with its hollow opening facing down, align the front positioning magnetic ring 6 with the outside of the independent female connector insertion surface and magnetically fix the protective box 31. At this time, the protective box 31 covers the entire MC4 photovoltaic connector 1, which can prevent impact, dust and water. The insertion section of the cable 2 is inside the protective box 31. Then, the support frame 33 is slid inward by the same direction fixing component 36, which drives the fixing soft rod 34 on the internal contact side to contact the cable 2 from both sides, preventing poor contact caused by various factors. The adjusting screw 3601 can flexibly control the degree of pressure of the fixing soft rod 34 on the cable 2.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the straightening and reinforcing component 4 includes two fixing plates 41, which are fixedly connected to both sides of the protective box 31. The front and rear sides of the fixing plates 41 are provided with positioning slots 42, and positioning blocks 43 are inserted into the inner side of the positioning slots 42.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, extension blocks 44 are fixedly connected to opposite sides of the two linkage sliders 35, and guide rods 45 are fixedly connected to the top of the extension blocks 44. Positioning blocks 43 are slidably connected to the outside of the guide rods 45.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, a compression spring 46 is fixedly connected to the bottom of the outer side of the guide slide rod 45, and the compression spring 46 is fixedly connected to the bottom of the positioning block 43.

[0030] In this embodiment: the support slide rod 32 is slidably connected to the inside of the bottom opening of the protective box 31 as a sliding carrier. The positioning block 43 in the positioning slot 42 of the fixing plate 41 is manually pulled down so that it slides down along the guide slide rod 45 and presses the compression spring 46. The support slide rod 32 can then slide towards the insertion side. Since the cable 2 has been pressed down, it is like holding it tightly and pushing it forward. The cable 2 is straightened and released after reaching the positioning slot 42 at the other end of the fixing plate 41. The positioning block 43 is engaged under the action of the compression spring 46. At this time, the support frame 33 and the fixing soft rod 34 both press down the cable 2 and abut against the rear side of the MC4 photovoltaic connector 1, which plays a double role in preventing loosening.

[0031] Specifically, such as Figure 3 , Figure 4As shown, the co-directional fixing assembly 36 includes an adjusting screw 3601, which is movably connected to the bottom of the support slide rod 32. A support vertical rod 3602 is movably connected to the front side of the adjusting screw 3601. The support vertical rod 3602 is fixedly connected to the front side of the support slide rod 32. A threaded slider 3603 is slidably connected to the outer side of the support vertical rod 3602. The threaded slider 3603 is threadedly connected to the outer side of the adjusting screw 3601.

[0032] Specifically, such as Figure 3 , Figure 4 As shown, both sides of the threaded slider 3603 are rotatably connected to the linkage rod 3604, and the other ends of the two linkage rods 3604 are rotatably connected to the bottom of the linkage slider 35.

[0033] In this embodiment: by manually turning the adjusting screw 3601 at the bottom of the support slide rod 32, the threaded slider 3603 with the built-in threaded sleeve will slide down along the support vertical rod 3602. This will cause the linkage rods 3604, which were originally in the shape of an inverted V on both sides, to rotate inward and reduce the opening. This will pull the linkage sliders 35 on both sides at the bottom of the support slide rod 32 to slide inward, and then cause the support frame 33 at the top of the linkage slider 35 to slide inward in the protective box 31 at the same time. This will cause the fixed flexible rod 34 inside the support frame 33 to contact the cable 2 from both sides.

[0034] Specifically, such as Figure 2 As shown, a travel hole 5 is provided on the rear side of the protective box 31.

[0035] Specifically, such as Figure 1 As shown, a positioning magnetic ring 6 is fixedly connected to the front side of the protective box 31.

[0036] In this embodiment: the protective box 31 is fitted over the cable 2 through the travel hole 5 on the rear side, and the protective box 31 is held with its hollow opening facing down, while the front positioning magnetic ring 6 is aligned with the outside of the independent female connector.

[0037] Working Principle: In the use of photovoltaic power generation equipment, in order to establish a low-resistance, high-stability electrical path, the male MC4 photovoltaic connector 1 needs to be plugged into a single pair of independent female sockets. However, in the existing MC4 photovoltaic connector 1, due to the influence of external wind force, temperature changes, its own weight and tension, and vibrations generated by other equipment connections, the cable 2 is easily affected by a combination of factors during the plugging process, which can lead to loosening and poor contact. To avoid the above situation, before plugging in the MC4 photovoltaic connector 1, the protective box 31 is fitted onto the outside of the cable 2 through the travel hole 5 on its rear side before the plugging operation. After the MC4 photovoltaic connector 1 is plugged in, Then, hold the protective box 31 with its open section facing down, aligning the front positioning magnetic ring 6 with the outer side of the independent female connector's insertion surface, and magnetically fix the protective box 31 to the shape of the female connector. After fixing, the protective box 31 will cover the entire MC4 photovoltaic connector 1, achieving a certain degree of impact resistance, dustproof, and waterproof effect. The insertion section cable 2 is also located inside the protective box 31. At this time, manually turn the adjusting screw 3601 at the bottom of the support slide rod 32. When the adjusting screw 3601 rotates, it drives the threaded slider 3603 with the built-in threaded sleeve to slide downward along the support vertical rod 3602. During its downward movement, the linkage rods 3604 on both sides, which were originally distributed in an inverted V-shape, will be... Simultaneously, the opening is narrowed as the sliding rod rotates inward, pulling the connecting sliders 35 located on both sides of the bottom of the support slider 32 inward. The top of the connecting slider 35 is fixedly connected to the support frame 33, causing the support frame 33 inside the protective box 31 to slide inward simultaneously. This causes the fixed flexible rod 34 on its internal contact side to contact the cable 2 from both sides, thus preventing poor contact caused by gravity, wind interference, vibration, and other factors. The degree of pressure of the fixed flexible rod 34 on the cable 2 can be flexibly controlled by adjusting the screw 3601. Furthermore, after this pressure state, to further prevent the male end of the MC4 photovoltaic connector 1 from loosening and to straighten the plug section of the cable 2, the support slider 32 also serves as a sliding carrier. The sliding connection is located inside the bottom opening of the protective box 31. After fixing, the positioning blocks 43 located inside the positioning slots 42 of the fixing plate 41 are pulled down manually first, so that the positioning blocks 43 slide down along the guide slide rod 45 and press the compression spring 46 between the bottom support of the guide slide rod 45 and accumulate elastic potential energy. At this time, the support slide rod 32 is no longer restricted by the positioning slot 42 and the positioning blocks 43, and can slide towards the insertion side of the MC4 photovoltaic connection cable. Since the top of the cable 2 has been pressed in the above process, it is in a state of gripping the cable 2 and pushing it forward, thereby straightening the insertion section. After reaching the positioning slot 42 at the other end of the fixing plate 41, the restriction on the positioning blocks 43 is released, so that it is quickly locked in place under the push of the compression spring 46.At this point, the aforementioned support frame 33 and fixed flexible rod 34 not only compress the cable 2 but also abut against the rear side of the MC4 photovoltaic connector 1, thus achieving a double anti-loosening effect. In summary, this represents an innovation in the electrical connection components of quick-plug photovoltaic power generation equipment.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
