Photovoltaic connector special for sea surface

Abstract

The invention discloses a photovoltaic connector special for sea surface, which comprises a plastic connecting shell, a metal connecting piece is arranged in the plastic connecting shell, the metal connecting piece is electrically connected with a cable, one end, extending out of the plastic connecting shell, of the cable is sealed and is provided with a plastic protective shell, and the plastic protective shell is electrically connected with the metal connecting piece. A flexible protective sleeve is formed at the sealing position of the cable and the plastic connecting shell through hot melt adhesive, and the flexible protective sleeve is located in the plastic protective shell. A plurality of salt discharging grooves are formed in the plastic protective shell. A plurality of ventilation openings which are communicated with one another are formed in a shell body of the plastic connecting shell. A plurality of exhaust holes are formed in a shell body of the plastic connecting shell, the exhaust holes penetrate into the plastic connecting shell, and waterproof breathable films are arranged on the exhaust holes. The cable is arranged to be of a spiral elastic structure. The photovoltaic connector provided by the invention has very good corrosion resistance and firmness, and is suitable for an environment with a relatively severe sea surface.

Description

technical field [0001] The invention relates to a photovoltaic connector, in particular to a sea surface photovoltaic connector used in sea areas. Background technique [0002] Due to the large area occupied by photovoltaic power stations and the limited land available at present, the location of photovoltaic power stations began to choose water surfaces, especially sea surfaces. The conventional construction method is to build a photovoltaic power station on the sea surface. The photovoltaic modules are installed on the floating board on the sea surface. The connector is very close to the sea surface. When the sea surface is stormy, the waves will directly hit the photovoltaic connector. Strong capacity, resulting in a significant shortening of the life of conventional connectors, and because there will be salt deposits on the connector, a large amount of salt will slowly deposit at the outlet of the connector, and as time accumulates, the salt will slowly corrode the conne...

Problems solved by technology

The conventional construction method is to build a photovoltaic power station on the sea surface. The photovoltaic modules are installed on the floating board on the sea surface. The connector is very close to the sea surface. When the sea surface is stormy, the waves will directly hit the photovoltaic connector. Strong capacity, resulting in a significant shortening of the life of conventional connectors, and because there will be salt deposits on the connector, a large amount of salt will slowly deposit at the outlet of the connector, and as time accumulates, the salt will slowly corrode the connection The sealing ring at the end of the connector, and then invade the inside of the connector, making the connector invalid, so there is a huge safety hazard in the use of traditional connectors on sea power stations
