Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic connectors, in particular to a connector for offshore photovoltaics. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of independent operation and grid-connected operation. Photovoltaic power generation system needs to connect multiple photovoltaic modules to form a photovoltaic module array through cables, and then output voltage to the outside. Photovoltaic connectors are indispensable devices for connecting photovoltaic modules to each other. The connector has a male end and a female end, and is equipped with conductive terminals inside. The internal conductive terminals are generally divided into pins and needle sleeves. The male end of the connector is connected to the female end of the connector, and the pins and needle sleeves are connected to each other.

[0003] In addition, the sealing structure on the traditional photovoltaic connector is mostly set on the plug-in rod structure. If multiple sets of sealing rings are set on the plug-in rod structure in order to improve the waterproof performance, there will be a problem of difficulty in plugging in.

[0004] Existing photovoltaic connectors are mostly made of plastic one-piece injection molding, and the terminals are mostly conventional copper terminals, with a generally low waterproof rating. This type of photovoltaic connector can meet normal use conditions, but in offshore photovoltaic applications, traditional photovoltaic connectors are easily corroded by seawater, and the waterproof rating of traditional photovoltaic connectors is also difficult to cope with marine climate conditions, which greatly shortens the service life of the photovoltaic connector.

[0005] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a connector for offshore photovoltaics to solve the above problems. Utility Model Content

[0008] The preferred technical solution is: a first annular groove is provided on the outer peripheral wall of the plug-in rod structure, and a first sealing ring is embedded in the first annular groove; a second annular groove is provided at the end of the plug-in rod structure, and a second sealing ring is embedded in the second annular groove.

[0009] The preferred technical solution is: a window communicating with the locking groove structure is provided on the outer wall of the socket body.

[0010] The preferred technical solution is: there are two locking groove structures, which are evenly distributed around the circumference of the plug hole structure; there are two locking buckle structures, which are evenly distributed around the circumference of the plug rod structure.

[0011] The preferred technical solution is that the socket body and the plug body are both made of nylon.

[0012] A preferred technical solution is that the surfaces of the male terminal and the female terminal are plated with a nickel layer and a tin layer in sequence.

[0013] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0014] The utility model provides a connector for surface photovoltaics, which improves the waterproof performance of the connector by arranging a sealing ring at the end of the plug-in structure. Compared with arranging the sealing ring on the outer periphery of the plug-in structure, this structure can avoid the problem of difficulty in plugging the socket connector and the plug connector due to too many sealing rings.
