Embodiment Construction

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0020] see figure 1 , figure 2 shown, figure 1 It is a schematic diagram of the front structure of the solar junction box of the present invention; figure 2 It is a schematic diagram of the back structure of the solar junction box of the present invention. The invention provides a solar junction box with a waterproof and breathable structure, which mainly solves the problem that the current solar junction box has poor waterproof and breathable performance when it is used outdoors, and is easily oxidized or blocked by wind and dust. Requirements for decompression inside the box.

Abstract

The invention provides a waterproof and ventilating structure of a solar junction box. A cover plate is installed on a hole in the front end of a body of the solar junction box, the cover plate is connected with the body in a sealed mode through a seal ring, exhaust holes are formed in the cover plate, a waterproof ventilating membrane is correspondingly arranged in the exhaust holes, the air in the solar junction box can be exhausted through the waterproof ventilating membrane, and water vapor outside the solar junction box cannot enter the solar junction box. In addition, due to the facts that sealing clamping grooves are further formed in the positions of connection between the solar junction box and cables of a cable connector, and sealing is carried out through corresponding cable seal rings, and the possibility that the water vapor enters the solar junction box through the positions of the connection between the solar junction box and the cables is eliminated. The waterproof and ventilating structure of the solar junction box is applicable to the solar junction box which is installed outdoors, and has the advantages that the effect of water resistance and the effect of ventilation are good, the service life is long, and the problem that devices inside the solar junction box can be easily influenced by the environment to cause reduction of performance is solved.

Description

technical field [0001] The invention relates to a solar junction box, in particular to a waterproof and breathable structure of a solar junction box. Background technique [0002] The photovoltaic solar junction box is used to connect the solar cell components. When in use, several photovoltaic solar junction boxes are used to connect several solar cell components in series according to the needs. The existing photovoltaic solar junction box structure includes: a box body, a box cover arranged on the box body and cooperating with the box body, and a positive bus bar and a negative bus bar that can be drawn out from the bottom of the solar cell module are arranged at the bottom of the box body. A number of connecting pieces are arranged in the box body in turn, diodes are arranged between the connecting pieces, and wiring holes are respectively arranged on the box body at the corresponding positions of the two connecting pieces on the left and right ends. When in use, the ca...
