Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to an aluminum alloy core flexible cable for a photovoltaic connection plate. Background Art

[0002] As we all know, with the vigorous development of the photovoltaic industry, the demand for efficient and stable power transmission components is growing. Aluminum alloy core flexible soft cables for photovoltaic connection panels have emerged. They use aluminum alloy as the conductor, have good conductivity and lightweight properties, and are matched with flexible insulation and sheath materials to adapt to complex installation environments. In photovoltaic systems, this cable is used to connect photovoltaic modules and connection panels, transmit the DC power generated by the modules to the connection panels, and then transmit it to the inverter after collection and distribution, realizing the conversion of electrical energy from DC to AC. It is a key component of the electrical connection of photovoltaic power stations.

[0003] At present, the Chinese invention with publication number: CN117095861B discloses a flexible multi-core aluminum alloy cable, which relates to the field of cable technology. Buffer springs are connected between the two ends of the movable block and the adjacent damping blocks. The bottom of the movable block is connected to a connecting block. A fixed ring is sleeved on the outside of the insulating layer and located between the support plate and the support ring. A connecting box is welded on the outside of the fixed ring. The connecting block is embedded in the adjacent connecting box. Limiting strips are filled between adjacent insulating layers. Limiting edges are evenly arranged on the outside of the limiting strips. When this invention is subjected to torsional force, the movable block is driven to move along the inside of the support ring through the fixed ring, and the buffer spring and the spring sheet are compressed. Under the elastic force of the buffer spring and the spring sheet, the conductor is prevented from being significantly deflected, and the cable is prevented from being seriously deformed. The limiting edges isolate the insulating layers on different conductors to prevent the conductors from rubbing against each other and causing damage to the insulating layer, thereby avoiding cable short circuit. There are gaps between adjacent limiting edges to ensure the flexibility of the cable.

[0004] The existing aluminum alloy core flexible cables for photovoltaic connection panels have the following disadvantages during installation: 1. Due to the lack of an auxiliary guide structure for real-time and quick positioning on the photovoltaic panel, the cable cannot be quickly positioned on the photovoltaic panel when connected to the photovoltaic connection panel, which reduces the flexibility of the cable when installed on the photovoltaic connection panel; 2. Due to the lack of an automatic sealing structure when connected to the photovoltaic connecting plate, the connection cannot be automatically sealed after connection, which reduces the sealing effect after connection. Summary of the Invention

Due to the auxiliary guide structure that can quickly limit the position on the photovoltaic panel in real time, it can be quickly limited on the photovoltaic panel when connected to the photovoltaic connection panel, which improves the flexibility of the cable when installed on the photovoltaic connection panel; 2. Because it has an automatic sealing structure when connected to the photovoltaic connecting plate, the connection can be automatically sealed after connection, which improves the sealing effect after connection.

The connecting mechanism can automatically seal the connection between the cable body and the photovoltaic connection board, thereby increasing the stability of the cable body when connected to the photovoltaic connection board.

The limit cone plate is limited by the limit ring, and the limit cone plate can limit the limit shell, so that a distance is maintained between the limit shell and the cable body, so that a space can be formed between the cable body and the limit shell, so as to facilitate the subsequent addition of protective gas to the internal space.

When a certain part of the limiting shell is damaged due to external force, only the space separated by the partition plate will be affected by the damaged part, thereby protecting the gas separation space from its influence.

Through its own soft thermal properties, the cable body can be bent and deformed outside the protective hose, thereby changing the installation direction of the cable body. The protective clamp can allow multiple protective plates to cover the surface of the protective hose in a ring shape, so that the surface of the protective hose can be protected by the shielding of the protective plate.

[0023] By adopting the above technical solution, an extrusion assembly is set up, and the extrusion shell can cooperate with the guide groove and the extrusion ring. The extrusion shell and the guide groove limit the sealing assembly, so that the extrusion ring can be placed in the sealing assembly. When the extrusion ring is connected to the threaded tube along the connecting end of the photovoltaic connecting plate, the extrusion ring is pushed along the connecting end, so that the extrusion ring applies the required pressure for the sealing of the sealing assembly.

[0025] By adopting the above technical solution and setting up a sealing component, the air-supplying airbag can cooperate with the pressing airbag and the sealing airbag. When the pressing airbag is subjected to pressure from the extrusion ring, its own gas can be delivered to the sealing airbag through the air-supplying airbag, so that the sealing airbag expands with the gradually increasing gas, and finally contacts the connection end of the photovoltaic connection board, so as to achieve the effect of sealing the connection end of the photovoltaic connection board and the cable body.

The guide component can reduce the friction between the cable body and the ground by rolling when it contacts the ground, thereby improving the flexibility of users when transporting the cable body. The positioning component can magnetically adsorb the limit component to the surface of the photovoltaic connection board, so as to quickly limit the cable body to the surface of the photovoltaic connection board, thereby improving the flexibility when connecting the cable body to the photovoltaic connection board.

By setting up a connecting mechanism, the installation component can cooperate with the extrusion component and the sealing component. The extrusion component can be limited by the installation component. When connected to the connection end of the photovoltaic connection board, the pressure generated when the connection end is connected can be used to allow the extrusion component to transmit the pressure to the sealing component, so that the sealing component can convert the pressure into its own deformation, thereby sealing the connection end of the photovoltaic connection board, thereby achieving the effect of automatic sealing during connection.
