Description

Technical Field

[0001] This application relates to the technical field of photovoltaic fuses, and in particular to a connector for photovoltaic fuses and a photovoltaic fuse assembly. Background Technology

[0002] In photovoltaic power generation systems, multiple photovoltaic strings are typically combined through combiner boxes. Fuses, as key overcurrent protection components, are often densely installed in arrays on rails. Currently, when operators turn on the fuses, they need to pull the individual handle of each fuse one by one. Due to the lack of an effective linkage mechanism in the existing technology, the handles of each fuse are independent of each other. When faced with dozens or even more fuses installed in rows, this method of operating one by one is extremely cumbersome, inefficient, and prone to human error due to missed operations or improper operation sequence. Summary of the Invention

[0003] To enable synchronous operation between the handles of multiple fuses, a connector for photovoltaic fuses and a photovoltaic fuse assembly are provided.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: A connector for a photovoltaic fuse is used to be disposed between two adjacent fuse handle portions. It includes a connector body and a connecting block. The connecting block is fixed on the two sides of the connector body opposite to the handle portion. The connecting block is fixed on the side of the handle portion opposite to or away from the connector body. The connecting block on the handle portion is fixedly connected to the connecting block on the connector body to restrict the movement of the connector body on the handle portion.

[0005] By adopting the above technical solution, the connector body is fixedly connected to the connecting block on the handle part through the connecting block, so that the connector body can firmly connect two adjacent handle parts. After the connecting blocks are fixed to each other, the movement of the connector body on the handle part is restricted. Thus, when operating one connector, two adjacent handle parts can be pulled synchronously, realizing the linkage operation of multiple fuse handle parts, improving the operation efficiency and reducing the need for operation one by one.

[0006] Preferably, the two ends of the connector body are respectively provided with curved guide portions.

[0007] By adopting the above technical solution, when the operator needs to pull the connector to simultaneously drive the two adjacent handles, the curved guide provides a stable and ergonomic point of force for the operator's fingers or tools, making it easier for the operator to apply force when pulling the connector, thus improving the convenience and stability of operation.

[0008] Preferably, the guide portion has several anti-slip protrusions along its own bending direction.

[0009] By adopting the above technical solution, the friction of the guide surface is increased, preventing the hand or tool from slipping during operation, enhancing the safety and reliability of operation, and reducing the risk of slippage.

[0010] Preferably, the upper surface of the connector body is flush with the upper surface of the handle portion.

[0011] By adopting the above technical solution, the gap between the connector body and the adjacent handle part is eliminated, reducing the accumulation of dust and impurities in the gap, which is beneficial for maintenance; the connector body avoids occupying additional installation space on the outside of the handle part, thus improving applicability.

[0012] Preferably, the connector body has positioning grooves on both sides opposite to the handle portion, and the positioning grooves are used for inserting the reinforcing ribs provided on the handle portion.

[0013] By adopting the above technical solution, before the connector body and the handle are connected to each other, the reinforcing rib and the positioning groove can be interlocked, which plays a role in pre-positioning and temporary fixation. This can effectively prevent the connector from shaking or misaligning relative to the handle during installation and before final fixation, improve the convenience and accuracy of the assembly process, and ensure the stability of the connector body and the handle after connection.

[0014] Preferably, the reinforcing ribs on one side of the handle portion are provided with at least one set, each set of reinforcing ribs is provided with at least two ribs, and an open positioning cavity is opened between the reinforcing ribs in the same set, and the connecting block on the connector body is located in the positioning cavity.

[0015] By adopting the above technical solution, before the connector body and the handle are finally fixed by the connecting block, the positioning cavity formed between the reinforcing ribs of the same group on the handle can pre-accommodate and restrict the connecting block on the connector body. During the installation process, it provides a circumferential constraint space for the connecting block, preventing the connector body from accidentally coming loose from between two adjacent handles before fixing, thus ensuring the smoothness of the assembly process and the stability of the intermediate state.

[0016] Preferably, the connecting block on the connector body is riveted to the connecting block of the handle portion by rivets.

[0017] By adopting the above technical solution, the connecting block and the connecting block on the handle are connected by riveting. Only a single rivet needs to be inserted into the aligned connecting block and riveted to complete the firm connection, thereby improving the assembly efficiency between the connecting body and the handle.

[0018] A photovoltaic fuse assembly includes: a plurality of fuse bodies, each of which is provided with a handle portion; It also includes the photovoltaic fuse connector as described in any of the above claims, wherein the connector body is disposed between adjacent handle portions, and wherein the connecting block on the handle portion and the connecting block on the connector body are riveted together by rivets.

[0019] By adopting the above technical solution, multiple fuse bodies are connected in series through multiple connector bodies and riveted together to form a whole, enabling efficient group synchronous operation of large-scale photovoltaic fuse arrays, improving the efficiency of photovoltaic system maintenance and reducing the labor intensity of operators.

[0020] In summary, this application has at least the following beneficial effects: 1. Before the connector body and the handle are connected to each other, the reinforcing rib and the positioning groove can be interlocked to achieve pre-positioning and temporary fixation. Only a single rivet needs to be inserted into the aligned connector block and riveted to complete the firm connection. This allows the connector body to firmly connect two adjacent handles. After the connector blocks are fixed to each other, the movement of the connector body on the handle is restricted. Thus, when operating one connector, two adjacent handles can be pulled synchronously, realizing the linkage operation of multiple fuse handles. 2. The curved guide provides a stable and ergonomic point of force for the operator's fingers or tools, making it easier for the operator to apply force when pulling the connector. The anti-slip protrusions increase the friction of the guide surface, preventing the hand or tool from slipping during operation and reducing the risk of slippage. 3. Multiple fuse bodies are connected in series through multiple connector bodies and riveted together to form a whole, enabling efficient group synchronous operation of large-scale photovoltaic fuse arrays, improving the efficiency of photovoltaic system maintenance and reducing the labor intensity of operators.

Detailed Implementation The following section provides a more detailed description, in conjunction with the accompanying diagrams: Example 1: As attached Figure 1 and attached Figure 2 As shown, a connector for photovoltaic fuses is used to be installed between the handle portions 1 of two adjacent fuses to realize the linkage operation of the two handle portions 1. It includes a connector body 2 and a connector block 3. The connector body 2 is a long strip-shaped block structure. The two sides of the connector body 2 face the two adjacent handle portions 1 respectively. The two ends of the connector body 2 are flush with the two ends of the handle portions 1. The upper surface of the connector body 2 is flush with the upper surface of the handle portion 1, so as to avoid gaps between the connector body 2 and the handle portion 1 and to avoid the connector body 2 protruding on the surface of the handle portion 1 and occupying additional installation space.

[0022] The connecting block 3 is cylindrical in shape. The connecting block 3 has a coaxial connecting hole 31 along its own axis. Several connecting blocks 3 are provided here. The connecting blocks 3 are fixedly connected to the two sides opposite to the connecting body 2 and the handle part 1. The connecting body 2 is also fixedly connected to the side opposite to or away from the handle part 1 and the connecting body 2. Two connecting blocks 3 are fixed on each side of the connecting body 2 and the handle part 1 and located at both ends. The connecting blocks 3 on the connecting body 2 and the connecting blocks 3 on the handle part 1 are coaxially aligned and connected by riveting through a rivet. Thus, the connecting blocks 3 are used to fix the connecting body 2 and the handle part 1, thereby restricting the movement of the connecting body 2 on the handle part 1.

[0023] As attached Figure 3 and attached Figure 4 As shown, both ends of the connector body 2 are provided with curved guide portions 21. The guide portions 21 are curved and concave towards the inside of the connector body 2. When the connector body 2 needs to be pulled to drive the handle portion 1, the concave guide portion 21 can provide a point of leverage for the operator. The guide portion 21 can also be curved and convex outwards from the connector body 2 or be a sloped surface or similar structure with guiding function. In addition, the guide portion 21 is also provided with several anti-slip protrusions 22 along its own curvature. The anti-slip protrusions 22 are integrally formed with the connector body 2. The several anti-slip protrusions 22 are evenly spaced to increase the friction of the guide portion 21 surface, prevent the hand or tool from slipping during operation, and reduce the risk of slippage.

[0024] Each handle part 1 has an integrally formed reinforcing rib 11 on both sides. There are two sets of reinforcing ribs 11 on each side of the handle part 1, and there are two reinforcing ribs 11 in each set. The reinforcing ribs 11 are strip-shaped, and there is a recessed and open positioning cavity 12 between the two reinforcing ribs 11 in the same set. The connecting body 2 is also provided with positioning grooves 23 on the two sides opposite to the handle part 1. The positioning grooves 23 are used for the reinforcing ribs 11 on the handle part 1 to be inserted. The positioning grooves 23 are groove-shaped and their size matches the reinforcing ribs 11 to ensure that the reinforcing ribs 11 can be accurately inserted into the positioning grooves 23. The reinforcing ribs 11 and the positioning grooves 23 form a mutual interlocking, which plays a role in pre-positioning and temporary fixation, preventing the connecting body 2 from shaking or misaligning relative to the handle part 1 during the installation process and before riveting.

[0025] The two connecting blocks 3 on one side of the connector body 2 are respectively located in the two positioning cavities 12 on one side of the handle part 1. The positioning cavity 12 can pre-accommodate and restrict the connecting blocks 3 on the connector body 2, and provide a circumferential constraint space for the connecting blocks 3 during the installation process, so as to prevent the connector body 2 from accidentally coming loose from the two adjacent handle parts 1 before it is fixed.

[0026] The implementation principle of this first embodiment is as follows: During the installation phase, the connector body 2 is first placed between the handle portions 1 of two adjacent fuses. By aligning the reinforcing ribs 11 on the handle portion 1 and inserting them into the positioning grooves 23 on both sides of the connector body 2, the connector body 2 and the handle portion 1 can be pre-positioned. At the same time, the connecting block 3 on the connector body 2 is correspondingly embedded in the positioning cavity 12 formed by the same group of reinforcing ribs 11 on the handle portion 1. The positioning cavity 12 forms a circumferential constraint on the connecting block 3, so that the connector body 2 is temporarily fixed before subsequent riveting and fixing, preventing it from shaking during the installation process. After the pre-positioning is completed, rivets are used to pass through the connecting holes 31 of the connecting block 3 on the aligned handle part 1 and the connecting holes 31 of the connecting block 3 on the connector body 2 in sequence, and are firmly formed by riveting process; when it is necessary to pull the handle part 1 of the fuse to connect the wires, the operator can act on the guide parts 21 at both ends of the connector body 2. The curved guide parts 21 provide the force point, and the anti-slip protrusions 22 on them increase the friction, thereby driving the connector body 2 to pull together with the handle part 1 connected to it.

[0027] Example 2: As attached Figure 3As shown, a photovoltaic fuse group includes multiple fuse bodies 4 and a handle 1. The fuse body 4 is the core component for realizing overcurrent protection. It is constructed as a closed cavity and contains protective elements such as fuse wires. When an overcurrent occurs in the circuit, the fuse wire will melt, thereby cutting off the circuit and protecting the equipment. The handle 1 is used for operation by the operator. It is constructed as a block structure, which is easy to hold and can be pulled out from the fuse individually. A connecting body 2 is provided between two adjacent handles 1. The connecting block 3 on the handle 1 and the connecting block 3 on the connecting body 2 are connected by rivets, realizing the linkage operation between multiple fuses and improving the efficiency of operating multiple fuses.

[0028] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
