Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically a photovoltaic support grounding connector. Background Technology

[0002] Photovoltaic (PV) mounting system grounding connectors are crucial components in PV systems, ensuring electrical continuity between the metal mounting structure and the grounding device. They are typically made of highly conductive metals (such as copper, galvanized steel, or copper-clad steel) and undergo anti-corrosion treatment to withstand long-term outdoor use. Their core function is to safely conduct any static charge or lightning-induced current that may accumulate on the PV mounting system to the ground, preventing equipment damage or personal injury. These connectors must meet high current-carrying capacity and low resistance requirements. Common types include crimp terminals, grounding clamps, and flat steel jumpers, adaptable to different mounting structures and installation scenarios. In engineering applications, the selection of connectors must strictly adhere to electrical specifications to ensure that the current-carrying capacity and mechanical strength meet system design standards.

[0003] The reliability of the connectors directly affects the lightning protection and grounding effectiveness of photovoltaic power plants. Especially in areas prone to thunderstorms, inferior or substandard connectors can lead to grounding failure, causing equipment malfunctions and even fire risks. Furthermore, the weather resistance (such as UV resistance and corrosion resistance) of the connectors is also a crucial indicator, ensuring stable conductivity even after long-term exposure to wind, rain, salt spray, and other environmental conditions. With the development of photovoltaic technology, some new connectors integrate monitoring functions, providing real-time feedback on grounding resistance status and further enhancing system safety.

[0004] If the grounding connectors of photovoltaic brackets are not tightened properly during installation, they are prone to loosening or displacement, resulting in increased contact resistance. Some connectors may have gaps with the bracket or grounding body due to insufficient clamping force or installation angle deviation, causing discontinuity in conductivity. In high-altitude operations or in windy conditions, unsecured connectors may shift or even fall off, damaging the integrity of the grounding circuit and significantly increasing system safety hazards.

[0011] Preferably, a retaining ring is fixedly connected to the outer side of the rotating shaft. The retaining ring contacts the inner wall of the base. The design of the retaining ring can limit the rotation of the rotating shaft.

[0012] Preferably, a knob is fixedly connected to the upper end of the rotating shaft, and the knob contacts the base. The knob design allows for easy rotation of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model optimizes the design of the connecting plate, connecting rod, and threaded rod assembly. By rotating the threaded rod, it is driven to engage with the threaded connection of the connecting plate, thereby precisely inserting the connecting rod into the limiting hole on the side wall of the mounting base to form a rigid snap-fit.

[0015] 2. This utility model optimizes the design of the slider, locking block and spring collaborative assembly. With the help of the spring pre-tightening force, the locking block is driven to elastically lock into the preset slot of the base to form an adaptive tight locking connection. By cooperating with the dynamic compensation characteristics of the spring, the locking process is ensured to be smooth and tight, effectively enhancing the limiting stability of the bracket and the base, avoiding loosening or displacement caused by vibration or external force after installation, and significantly improving the overall installation stability of the photovoltaic bracket grounding connection.

A spring 34 is provided on the outer side of the fixing rod 33. One end of the spring 34 contacts the slider 3, and the other end of the spring 34 contacts the bracket 2. The spring 34 is designed to drive the locking block 31 to engage with the base 1. A push block 35 is fixedly connected to the upper end of the slider 3 and contacts the bracket 2. A fixing mechanism 4 is provided on the base 1.

[0023] Please see Figure 2-4The fixing mechanism 4 includes a connecting plate 41. The connecting plate 41 is slidably connected inside the base 1. A connecting rod 42 is fixedly connected to the side of the connecting plate 41 that is far apart from each other. The connecting rod 42 is slidably connected to the base 1. A threaded rod 43 is connected inside the base 1 through a bearing. The outer side of the threaded rod 43 is provided with positive and negative threads. The threaded rod 43 is threadedly connected to the connecting plate 41. Through the design of the threaded rod 43, it can drive the two connecting plates 41 to move at the same time. A rotating shaft 44 is rotatably connected inside the base 1.

[0024] Please see Figure 2-4 The lower end of the rotating shaft 44 is fixedly connected to a first bevel gear 45, and the outer side of the threaded rod 43 is fixedly connected to a second bevel gear 46. The first bevel gear 45 and the second bevel gear 46 mesh. The outer side of the rotating shaft 44 is fixedly connected to a retaining ring 47, which contacts the inner wall of the base 1.

[0025] The specific implementation process of this utility model is as follows: In use, the base 1 is installed into the pre-installed mounting base, and then the knob 48 is rotated to make the knob 48 drive the rotating shaft 44 to rotate, which in turn drives the first bevel gear 45 to rotate, which in turn drives the second bevel gear 46 to rotate, which in turn drives the threaded rod 43 to rotate, which causes the threaded rod 43 to move with the connecting plate 41, thereby causing the connecting plate 41 to drive the connecting rod 42 to insert into the side wall of the mounting base, which can limit the base 1 and thus keep the base 1 stable after installation;

Then the locking block 31 is placed into the slot 32. Then the push blocks 35 are released, and the spring force of the spring 34 drives the slider 3 to move, so that the slider 3 drives the locking block 31 to engage with the bracket 2, thus allowing the bracket 2 to be installed on the base 1.
