Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cables, and particularly relates to an aluminum alloy core flexible flexible cable for a photovoltaic connecting plate. BACKGROUND

[0002] As is known to all, with the vigorous development of the photovoltaic industry, the demand for efficient and stable power transmission components is increasing, and the aluminum alloy core flexible flexible cable for the photovoltaic connecting plate emerges as the times require. The cable has good electrical conductivity and light weight characteristics with aluminum alloy as the conductor, and is matched with flexible insulation and sheath materials, and can adapt to complex installation environment. In the photovoltaic system, the cable is used to connect the photovoltaic components and the connecting plate, and transmit the direct current generated by the components to the connecting plate, and then transmit to the inverter after collection and distribution, so as to realize the conversion of electric energy from direct current to alternating current, and is a key component for electrical connection of photovoltaic power stations.

[0003] At present, a flexible multi-core aluminum alloy cable is disclosed in Chinese invention CN117095861B, which belongs to the technical field of cables. The movable block is connected with the adjacent damping block through the buffer spring at both ends, and the movable block is connected with the connecting block at the bottom. The fixed ring is sleeved between the support disc and the support ring outside the insulation layer, and the connecting box is welded outside the fixed ring. The connecting block is embedded in the adjacent connecting box. The limiting strips are filled between the adjacent insulation layers, and the limiting edges are uniformly arranged outside the limiting strips. When the cable is subjected to torsional force, the movable block is driven to move along the inside of the support ring through the fixed ring. The buffer spring and the spring sheet are compressed. Under the action of the elastic force of the buffer spring and the spring sheet, the conductor is prevented from being deflected greatly, and the cable is prevented from being deformed seriously. The limiting edges isolate the insulation layers on different conductors to prevent the conductors from rubbing against each other to damage the insulation layer, thereby avoiding cable short circuit. The gaps are left between the adjacent limiting edges to ensure the flexibility of the cable.

[0048] As shown in Figure 3 The limiting assembly 21 comprises a limiting shell 211, a limiting cone plate 212 and a limiting ring 213.

By arranging the indication assembly 23, the limiting plate 231 can cooperate with the limiting clamping plate 232 and the fluorescent plate 233. The limiting clamping plate 232 is limited by the limiting plate 231, so that the limiting clamping plate 232 can be clamped to the limiting plate 231 for easy disassembly. The fluorescent plate 233 can absorb ambient light during the day and store it at night to provide auxiliary lighting.

The protection plate 263 is rotatably connected to the surface of the protection clamping ring 262. By arranging the protection assembly 26, the protection hose 261 can cooperate with the protection clamping ring 262 and the protection plate 263. The protection hose 261 can limit between each limiting ring 213. By its own soft thermal property, the cable body 1 can be bent and deformed in the protection hose 261 to change the installation direction of the cable body 1. The protection clamping ring 262 can make the multiple protection plates 263 cover the surface of the protection hose 261 in a ring shape, so that the surface of the protection hose 261 can be protected by the shielding of the protection plate 263.

[0054] The use process is briefly described as follows: first, the protective gas is injected into the limiting shell 211 until the protective gas is contained in each partition plate 221, then the limiting ring 213 and the protection hose 261 are sequentially sleeved on the surface of the cable body 1 until the installation of the surface of the cable body 1 is completed, then the cable body 1 and the positioning mechanism 2 are transported to the connecting end of the photovoltaic connecting plate. When the positioning mechanism 2 and the cable body 1 are transported, the guide ball 243 will roll along the guide sliding groove 242 when it is in contact with the ground, and will roll with the movement of the limiting shell 211 to reduce the friction between the limiting shell 211 and the ground. Then, the magnet plate 253 corresponding to the cable body 1 at the photovoltaic connecting plate is attached to one side of the magnet plate 253 containing a magnetic metal at the photovoltaic connecting plate, until all the limiting shells 211 corresponding to the cable body 1 are adsorbed on the photovoltaic connecting plate by the magnet plate 253. When it is from day to night, the fluorescent plate 233 will emit fluorescence to the surrounding, and when the fluorescent plate 233 is damaged by external force at the corresponding position, the user can quickly find the damaged position by the limiting shell 211 without the fluorescent plate 233 when he normally patrols and checks at night.
