Description

Technical Field

[0001] This utility model relates to the technical field of terminal block structure; more specifically, it relates to the quick-connect terminal block structure of photovoltaic grid-connected cabinets. Background Technology

[0002] The quick-connect terminal block structure of photovoltaic grid-connected cabinets is typically designed to simplify cable connections, improve installation efficiency, and ensure the reliability of electrical connections. They may employ spring connections, screw connections, or plug-in connections, allowing for quick plugging and unplugging and rewiring. Quick-connect terminals are usually made of corrosion-resistant materials to ensure a long service life in outdoor environments.

[0003] Currently, while existing terminal block structures offer good wiring performance, installation often requires multiple tools and procedures, leading to low installation efficiency. Furthermore, disassembly and maintenance are inconvenient, reducing the equipment's practicality. Most devices also lack moisture-proof design, allowing moisture to penetrate the joints, increasing the risk of short circuits and further weakening the equipment's stability and reliability. Therefore, a quick-connect terminal block structure for photovoltaic grid-connected cabinets is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a quick-connect terminal structure for photovoltaic grid-connected cabinets to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a quick-connect terminal structure for a photovoltaic grid-connected cabinet, comprising:

[0006] The terminal block body has a connecting structure inside, and a protective structure inside the connecting structure. The connecting structure includes a rotating groove and an operating plate. There are two sets of rotating grooves, which are respectively opened on both sides of the outer surface of the terminal block body. The protective structure includes an insertion groove, which is opened on one side of the outer surface of the operating plate.

[0007] Preferably, the connection structure further includes a rotating plate, and there are two sets of rotating plates. The two sets of rotating plates are respectively inserted into the interior of two sets of rotating slots. One end of the rotating plate is fixedly connected to an operating plate on the outside of the terminal body, and the other end of the rotating plate is fixedly connected to a connecting plate inside the terminal body. The connecting plate has sliding grooves on both sides inside, and a sliding rod is inserted into the sliding groove. One end of the sliding rod is fixedly connected to a clamping plate. One side of one end of the two sets of rotating slots has a groove, and a spring is fixedly connected inside the groove. One end of the spring is fixedly connected to a limiting circular plate. A blocking block is fixedly connected to the outer surface of the limiting circular plate away from the spring. This design allows for quick connection of the circuit.

[0008] Preferably, the other end of the two sets of slide rods is fixedly connected to a limiting plate, and the outer surface of the limiting plate is in contact with the outer surface of the connecting plate. This design can limit the slide rod, so that it always moves inside the slide groove.

[0009] Preferably, the internal dimensions of the groove are adapted to the external dimensions of the limiting circular plate, which makes the movement of the blocking block more stable.

[0010] Preferably, both sides of the outer surface of the shielding block are inclined, which facilitates the contact of the inclined surface of the shielding block with the rotating plate when it moves inside the rotating groove.

[0011] Preferably, the protective structure further includes a protective plate, and the protective plate is provided in two sets. The two sets of protective plates are respectively inserted into the inner sides of the insertion slot, and one end of each protective plate is hinged to a hinge seat. This hinged connection design allows the two sets of protective plates to be in a closed or open state, which is convenient for the staff to install them.

[0012] Preferably, one side of the outer surface of the two sets of protection plates is arc-shaped, and one end of the arc-shaped surface can fit more closely to the outer surface of the circuit.

[0013] The technical effects and advantages of this utility model are as follows: By rotating the operating plate, the rotating plate moves to one end inside the rotating groove, allowing it to contact the inclined surface of the blocking block. When the rotational force is greater than the spring force, the blocking block moves back into the groove until it reaches a suitable position. Then, the rotating plate can be moved to the bottom of one end of the rotating groove. At this time, the sliding rod also moves inside the groove, driving the two sets of clamping plates to form a clamping effect. Simultaneously, under the elasticity of the spring, the blocking block can be ejected outward and block the rotating plate. This design allows for quick installation of the wiring, and the blocking effect of the blocking block maintains the stable clamping effect of the two sets of clamping plates. This allows the equipment to complete the wiring installation without the aid of tools, improving installation efficiency and thus enhancing the practicality of the equipment to a certain extent.

[0014] By hinged rotation of two sets of protective plates, which then come into contact with each other and wrap around the outer surface of the circuit, the two sets of protective plates are inserted into the insertion slot. This design, under the action of the two sets of protective plates, can extend the interface position at one end of the terminal block. At the same time, one end of the protective plate is arc-shaped, which allows it to fit more closely to the surface of the circuit, reducing the gap between the circuit and the protective plate, and minimizing the intrusion of moisture into the joint, thereby reducing the risk of short circuits and further enhancing the stability and reliability of the equipment. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The terminal block structures involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1, as Figures 1-3 As shown, this embodiment proposes a quick-connect terminal structure for a photovoltaic grid-connected cabinet, including:

[0022] The terminal block body 1 has a connection structure 2 inside, and a protective structure 3 is provided inside the connection structure 2.

[0023] The connecting structure 2 includes a rotating groove 21 and an operating plate 23. Two sets of rotating grooves 21 are provided, each located on one side of the outer surface of the terminal block body 1. The connecting structure 2 also includes two rotating plates 22, each inserted into one of the rotating grooves 21. One end of each rotating plate 22 is located on the outside of the terminal block body 1 and is fixedly connected to the operating plate 23. The other end of each rotating plate 22 is located inside the terminal block body 1 and is fixedly connected to a connecting plate 24. Sliding grooves 25 are provided on both sides of the connecting plate 24, and sliding rods 26 are inserted into the sliding grooves 25. One end of each sliding rod 26 is fixedly connected to a clamping plate 27. Grooves 25 are provided on one side of each of the two rotating grooves 21. 8. A spring 29 is fixedly connected inside the groove 28, and a limiting circular plate 210 is fixedly connected to one end of the spring 29. A blocking block 211 is fixedly connected to the side of the outer surface of the limiting circular plate 210 away from the spring 29. With the rotation of the connecting plate 24, the slide 25 can move on the outer surface of the slide rod 26. At the same time, one end of the two ends of the slide 25 is close to the inner wall of the connecting plate 24, and the other end is close to the outer surface of the connecting plate 24. This allows the slide rod 26 to drive the clamping plate 27 to form a clamping effect when it is at one end of the slide 25. When the slide rod 26 is at the other end of the slide 25, it can form an unfolding effect. At the same time, the side of the two sets of clamping plates 27 that are close to each other is arc-shaped, which can increase the contact area and thus enhance the clamping and positioning effect of the line.

[0024] The other end of the two sets of slide rods 26 is fixedly connected to a limiting plate, and the outer surface of the limiting plate is in contact with the outer surface of the connecting plate 24. The limiting plate and the outer surface of the connecting plate 24 are always in contact, which can limit the movement position of the slide rods 26 and the clamping plate 27, so that they always maintain a stable movement direction.

[0025] The internal dimensions of the groove 28 are adapted to the external dimensions of the limiting circular plate 210. This design can limit the blocking block 211 and prevent the blocking block 211 from falling out of the groove 28.

[0026] Both sides of the outer surface of the blocking block 211 are inclined. When the rotating plate 22 moves inside the rotating groove 21, it can contact the inclined surface of the blocking block 211, so that the rotating plate 22 can press the blocking block 211 back into the groove 28, thereby facilitating the movement of the rotating plate 22 to one end of the rotating groove 21 and making the movement of the rotating plate 22 smoother.

[0027] Example 2, as Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0028] The protective structure 3 includes an insertion slot 31, which is located on one side of the outer surface of the operating plate 23. The protective structure 3 also includes a protective plate 32, which is provided in two sets. The two sets of protective plates 32 are respectively inserted into the inner sides of the insertion slot 31, and one end of each protective plate 32 is hinged to a hinge seat 33. The internal dimensions of the insertion slot 31 are adapted to the dimensions of one end of the two sets of protective plates 32 after they are combined. When the two sets of protective plates 32 are combined and inserted into the interior of the insertion slot 31, the inner wall of the insertion slot 31 can limit the outer surface of the protective plate 32, so that it can always maintain a stable connection effect without applying external force.

[0029] One side of the outer surface of the two sets of protection plates 32 is arc-shaped. This arc-shaped surface can help staff quickly identify the location. At the same time, one end of the arc-shaped surface of the protection plate 32 is the same size as the opening of one end of the terminal block body 1, so that the protection plate 32 can fully fit the outer surface of the line and be extended to avoid moisture from entering the line joint position as much as possible.

[0030] Working principle: When using the equipment, first insert one end of the line into the body 1 of the terminal block, then rotate the operating plate 23 so that the rotating plate 22 moves to one end inside the rotating groove 21, allowing the rotating plate 22 to contact the inclined surface of the blocking block 211. When the rotational force is greater than the elastic force of the spring 29, the blocking block 211 can be moved back into the groove 28 until the blocking block 211 moves back to the appropriate position. Then, the rotating plate 22 can be moved to the bottom end of one end of the rotating groove 21. At this time, the slide 25 will also move along the outer surface of the slide rod 26, driving the two sets of clamping plates 27 to form a clamping effect. Under the elastic action of the spring 29, the blocking block 211 can be ejected outward and block the rotating plate 22. At this time, the clamping effect of the clamping plate 27 can be maintained to complete the connection of the line. Then, the body 1 of the terminal block is placed inside the photovoltaic grid-connected cabinet. The connection is completed to complete the wiring operation. When the line needs to be repaired, simply rotate the operating plate 23 in the opposite direction with great force, so that the rotating plate 22 is engaged with the inner wall of the rotating groove 21 and moves to the other end. At this time, the outer surface of the rotating plate 22 will again abut the inclined surface of the blocking block 211, so that the blocking block 211 moves back into the groove 28. When the blocking block 211 moves back to the appropriate position, the operating plate 23 can be rotated again, so that the connecting plate 24 will also rotate in the opposite direction, and the slide 25 will move in the opposite direction along the outer surface of the slide rod 26, driving the two sets of clamping plates 27 to unfold, thereby canceling the clamping and positioning operation of the line. At this time, the line can be taken out from the inside of the terminal body 1, which is convenient for maintenance personnel to perform maintenance operations. After the maintenance is completed, simply repeat the above operation to reconnect the line to the terminal body 1 to complete the wiring operation.

[0031] When using the equipment, place the line in the middle of the two sets of protection plates 32, then hinge and rotate the two sets of protection plates 32 so that they abut against each other and wrap around the outer surface of the line. Then, insert the two sets of protection plates 32 into the insertion slot 31 simultaneously. At this time, under the action of the insertion slot 31, the protection plates 32 can be limited to maintain a stable abutment effect. Under the action of the protection plates 32, the line can be extended for protection, preventing bending at the wiring port. At the same time, one side of the protection plate 32 has an arc design, which can fully fit the surface of the line, effectively reducing the gap between the protection plate and the line, and minimizing the penetration of moisture, so as to achieve the effect of protection and moisture prevention. When disassembly or maintenance is required, simply pull the protection plate 32 outward to remove it from the insertion slot 31, and then hinge and rotate the protection plate 32 to remove it from the outer surface of the line. The operation is relatively simple and convenient, and quick disassembly and installation can be performed. The above is the complete working principle of this utility model.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
