Description

Technical Field

[0001] The utility model relates to the field of cable connection protection, in particular to a connection device for irradiation cross-linked photovoltaic cables. Background Art

[0002] Irradiation cross-linked photovoltaic cable is a special cable that uses radiation cross-linking technology in the production process and is used in solar photovoltaic systems. This cable uses high-energy radiation to act on polymer materials to rearrange and cross-link the molecules in the polymer chain, thereby improving its heat resistance, aging resistance and electrical properties. Irradiation cross-linked photovoltaic cables usually use special materials such as cross-linked polyethylene or cross-linked polyvinyl chloride as insulation layers to ensure long-term stable operation in high temperature and outdoor environments. This cable has good weather resistance, UV resistance and chemical corrosion resistance, and is suitable for solar photovoltaic power generation systems under various climatic conditions, providing reliable power transmission and connection for solar power generation. This cable often requires a connection device to ensure the safe operation and long-term stability of the photovoltaic system.

[0003] In traditional photovoltaic cable connection devices, the connector housing is the outer shell of the connection device, usually made of weather-resistant and corrosion-resistant materials, such as engineering plastics or metal alloys. The cable clamp is used to fix the cable to prevent it from moving or falling off due to external forces. It is usually made of elastic materials or metals. The conductor connector is used to connect the cable conductors, usually using crimping or threaded connection methods to ensure stable and reliable current transmission.

[0004] However, the connector shell fixing method used in traditional photovoltaic cable connection devices is often a metal plastic shell and bolt fixing. This fixing method often makes it impossible for the photovoltaic cable to twist when it is fixed inside, restricting the movement, bending and twisting of the photovoltaic cable, increasing the stress and damage to the wire due to movement, making the wire unable to adapt to various installation scenarios and movement requirements, and reducing the practicality and protection function of this connection device for photovoltaic cable applications. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a connection device for irradiation cross-linked photovoltaic cables, aiming to improve the problem that traditional photovoltaic cable connection devices make the conductors unable to adapt to various installation scenarios and movement requirements, reducing the practicality and protection function of this connection device for photovoltaic cable applications.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a connection device for irradiation cross-linked photovoltaic cables, including a connecting plate, the side wall of the connecting plate is slidably connected to a slide, the side wall of the slide is fixedly connected to a fixed plate, the bottom of the fixed plate is fixedly connected to a connecting column, the side wall of the connecting plate is fixedly connected to a support, the outer wall of the connecting column is provided with a spring, and the side wall of the connecting plate is provided with a rotating component.

[0007] Furthermore, the rotating assembly includes a rotating plate, and a side wall of the rotating plate is rotatably connected to the side wall of the slide.

[0008] Furthermore, the side wall of the connecting plate is fixedly connected with a slide rail.

[0009] Furthermore, a flexible clamp is slidably connected inside the slide rail.

[0010] Furthermore, the rotating plate side wall is rotatably connected to the flexible splint side wall.

[0011] Furthermore, a stranded flexible conductor is provided on the side wall of the flexible clamping plate.

[0012] Furthermore, both ends of the stranded flexible conductor are fixedly connected with elastic insulating sleeves.

[0013] Furthermore, a telescopic sleeve is arranged inside the elastic insulating sleeve.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, firstly, the slide is pressed to make the slide slide on the side wall of the connecting plate, and then the fixed plate drives the connecting column to slide inside the support platform. Through this operation, the rotation of the turn plate can be activated. The rotation of the turn plate makes multiple flexible splints slide inside the slide rail to achieve rapid disassembly and assembly of the cable, thereby making the fixing method of this irradiated cross-linked photovoltaic cable more flexible, which is convenient for maintaining the insulation performance and stability of the connecting part when the wire is bent or moved.

[0016] 2. In the utility model, the wires have good flexibility and bendability through structures such as twisted wire flexible conductors and telescopic sleeves, and can move freely when bending or twisting is required without being damaged. They can bend and twist within a certain range to adapt to different installation scenarios and movement requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figures 1 to 3 The utility model provides an embodiment: a connection device for irradiation cross-linked photovoltaic cables, including a connection plate 1, a slide 2 is slidably connected to the side wall of the connection plate 1, a fixed plate 3 is fixedly connected to the side wall of the slide 2, a connection column 4 is fixedly connected to the bottom of the fixed plate 3, a support 6 is fixedly connected to the side wall of the connection plate 1, a spring 5 is sleeved on the outer wall of the connection column 4, and a rotating component is arranged on the side wall of the connection plate 1.

[0024] Specifically, first press the slide 2, and the slide 2 slides on the side wall of the connecting plate 1 after being subjected to force. The movement of the slide 2 also drives the fixed plate 3 on its side wall to move synchronously, and the fixed plate 3 then makes the connecting column 4 at its bottom slide inside the support 6. This process drives the rotation of the rotating plate 7, affecting the activation of the bottom fixed structure. This design makes the fixing method of the irradiation cross-linked photovoltaic cable more flexible, which is convenient for maintaining the insulation performance and stability of the connecting part when the wire is bent or moved. When the rotating plate 7 is rotated by force, the slide rail 8 on the side wall of the rotating plate 7 slides inside the flexible splint 9. The movement of the flexible splint 9 relative to the rotating plate 7 can effectively fix or unlock the irradiation cross-linked photovoltaic cable, thereby realizing the rapid disassembly and assembly of the cable. This design scheme greatly facilitates the maintenance and repair of the irradiation cross-linked photovoltaic cable, and improves work efficiency and operational convenience.

[0025] Reference Figure 2 and Figure 3The rotating assembly includes a rotating plate 7, the side wall of the rotating plate 7 is rotatably connected to the side wall of the slide table 2, the side wall of the connecting plate 1 is fixedly connected to the slide rail 8, the inside of the slide rail 8 is slidably connected to the flexible clamping plate 9, the side wall of the rotating plate 7 is rotatably connected to the side wall of the flexible clamping plate 9, the side wall of the flexible clamping plate 9 is provided with a stranded flexible conductor 10, the two ends of the stranded flexible conductor 10 are fixedly connected with an elastic insulating sleeve 11, and a telescopic sleeve 12 is provided inside the elastic insulating sleeve 11.

[0026] Specifically, the stranded flexible conductor 10 is made of high-quality copper stranded wire or soft copper wire, which has excellent flexibility and conductivity. They can remain stable under different degrees of bending and torsion, and are therefore suitable for various installation scenarios and dynamic movement requirements. In order to further enhance its durability and protection, a telescopic sleeve 12 is usually used to cover and protect it. These sleeves are usually made of elastic materials such as rubber or silicone, which can effectively protect the conductor part from damage by the external environment and provide good insulation protection when the conductor moves or bends. At the same time, the elastic insulating sleeve 11 has a rotatable or retractable design, so that it can adapt to various connection requirements. This design enables the flexible connection device to flexibly cope with wire connections in different situations and ensure the stability and electrical performance of the connection. The working principle of the flexible connection device lies in its material and design characteristics, which make it have sufficient flexibility and elasticity, can adapt to the movement, bending and torsion of the wire, and maintain the reliability and stability of the connection. The use of a flexible connection device can effectively reduce the stress and damage to the wire due to movement, while providing reliable insulation protection to ensure the safety and reliability of the connection. The design of this device can not only meet complex engineering requirements, but also extend the service life of the wire.

[0027] Working principle: when it is necessary to connect and fix the irradiated cross-linked photovoltaic cable, first press the slide 2. After the slide 2 is subjected to force, it slides on the side wall of the connecting plate 1. While the slide 2 slides, it drives the fixed plate 3 on its side wall to move synchronously. The fixed plate 3 then makes the connecting column 4 at its bottom slide inside the support 6. This process can drive the rotation of the rotating plate 7, thereby affecting the activation of the bottom fixed structure, thereby making the fixing method of this irradiated cross-linked photovoltaic cable more flexible, which is convenient for maintaining the insulation performance and stability of the connecting part when the wire is bent or moved. While the rotating plate 7 is subjected to force and rotates, the slide rail 8 on the side wall of the rotating plate 7 then slides inside the flexible splint 9. The relative movement of the flexible splint 9 can effectively fix or unlock the irradiated cross-linked photovoltaic cable, thereby realizing the rapid disassembly and assembly of the cable, which is convenient for the maintenance and inspection of the irradiated cross-linked photovoltaic cable. The stranded flexible conductor 10 is made of copper stranded wire or soft copper wire, and has high flexibility and conductivity. They can bend and twist within a certain range to adapt to different installation scenarios and movement requirements. The telescopic sleeve 12 is usually made of elastic materials such as rubber or silicone to cover and protect the conductor part. They can maintain the stability of the connection when the conductor moves or bends, and provide good insulation protection. The elastic insulating sleeve 11 has a rotatable or retractable design, which enables it to flexibly adapt to the connection requirements in various situations. The working principle of these soft connection devices lies in their materials and designs that make them flexible and elastic, able to adapt to the movement, bending and twisting of the wires, and maintain the stability and electrical performance of the connection. The soft connection device can reduce the stress and damage to the wires due to movement, while providing good insulation protection to ensure the safety and reliability of the connection.
