Photovoltaic junction box with good sealing performance and dismounting method

Abstract

The invention discloses a photovoltaic junction box with good sealing performance and a dismounting method, and the junction box comprises a housing, the interior of the housing is fixedly connected with a convex block, the two side walls of the convex block are fixedly connected with first sliding blocks, one side wall of the housing is provided with a limiting groove, the interior of the limiting groove is provided with a movable mechanism, and one side, close to the limiting groove, of the housing is fixedly welded with a first limiting housing. An inserting block is arranged at the top of the first limiting housing, a limiting mechanism is arranged in the first limiting housing, a sliding cover is arranged at the top of the housing, two sliding grooves are symmetrically formed in the sliding cover, the first sliding block is matched with the sliding grooves, and a fixing box is arranged on the side, away from the limiting grooves, of the housing. The junction box has the beneficial effects that the sliding cover can be limited and fixed through the fixing mechanism, the shell and the sliding cover can be fixed through the movable mechanism, the inserting block can be limited and fixed through the limiting mechanism, when the inserting block is fixed, the first fixing block is shrunk, therefore, the sliding cover is convenient to move.

Description

technical field [0001] The invention relates to a junction box, in particular to a photovoltaic junction box with good sealing performance, and belongs to the technical field of junction box processing. Background technique [0002] The photovoltaic junction box is mainly used to connect and protect solar photovoltaic modules. If the sealing effect of the photovoltaic junction box is not good, dust will enter the interior of the junction box, so a photovoltaic junction box with good sealing is required. [0003] However, most of the existing junction boxes do not have a good sealing effect, which makes it easy for too much dust or rainwater to enter the interior of the junction box during long-term use. At the same time, because most junction boxes are fixed and connected by bolts, Furthermore, when it is necessary to disassemble and assemble the junction box, it takes a lot of disassembly and assembly time, thereby affecting work efficiency.
