Abstract

The invention discloses a photovoltaic assembly junction box with electrical connection protection. The photovoltaic assembly junction box comprises a box body; a wiring terminal row is arranged in the box body; a wire outlet is formed in the left side of the box body; a wire inlet sleeve is arranged on the right side of the box body; a wire inlet groove is formed in the wire inlet sleeve; fixingpieces are connected to the upper side and the lower side of the box body; screw holes are formed in the fixing pieces; a box cover is arranged on the box body; inclined plates are connected to the left end and the right end of the box cover respectively; the inclined plates are made of thin steel sheets; rubber strips are arranged at the upper parts and the lower parts in the wire inlet groove ofthe wire inlet sleeve and the wire outlet; a groove is formed in the joint between the top of the box body and the box cover; and a strip column is arranged in a position, corresponding to the groove, of the box cover. When the box cover is closed, the strip column on the box cover is embedded into the groove, and meanwhile, a sealing gasket on the box cover is tightly attached to the box body, so that the situation that wires in the box body are affected with damp to be corroded and even are short-circuited to start fire because rainwater permeates into the box body from the joint is avoided, and the safe use capability is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wire connection equipment, in particular to a junction box for photovoltaic modules with electrical connection protection. Background technique [0002] With global climate change and increasingly serious environmental pollution problems, the green and renewable energy industry has developed rapidly in the past ten years. Solar energy is a renewable resource, and the solar cell technology that uses the photovoltaic effect to generate electricity has attracted worldwide attention. Solar cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium selenide copper and other materials, which can convert light energy into electrical energy. At present, photovoltaic modules composed of multiple solar cells are widely used to build various photovoltaic power generation systems, or used as building curtain walls to build energy-saving and environmentally friendly b...
