Problems solved by technology

Existing solar photovoltaic junction boxes generally use a sealing ring with a circular cross-section between the box body and the box cover to increase waterproof performance. This waterproof structure is used in practical applications, especially in working conditions that require a high waterproof level. Under the environment, the waterproof performance is unreliable, and it is easy to cause the components in the junction box to be damp and reduce the service life of the solar photovoltaic junction box

Abstract

The invention discloses a solar photovoltaic connecting box, and belongs to the field of solar photovoltaic power generation devices. In order to solve the waterproof problem of the solar photovoltaic connecting box, the solar photovoltaic connecting box enlarges the contact areas among a box body, a box cover and a sealing ring, and at the same time protruding ribs are added on the sealing surfaces of the box body and the box cover. When the solar photovoltaic connecting box works, the protruding ribs of the box body and the box cover are pressed into the sealing ring, waterproof performance is increased, and service lifer of the solar photovoltaic connecting box is prolonged.

Description

technical field [0001] The invention relates to a solar photovoltaic junction box, which belongs to the field of solar photovoltaic power generation equipment. Background technique [0002] At present, solar technology is developing rapidly, and the waterproof requirements for solar photovoltaic junction boxes are also getting higher and higher. Existing solar photovoltaic junction boxes generally use a sealing ring with a circular cross-section between the box body and the box cover to increase waterproof performance. This waterproof structure is used in practical applications, especially in working conditions that require a high waterproof level. Under the environment, the waterproof performance is unreliable, and it is easy to cause the components in the junction box to be damp and reduce the service life of the solar photovoltaic junction box. Contents of the invention [0003] In view of the above-mentioned defects in the background technology, the technical problem ...
