Technical Field

[0001] The utility model relates to the technical field of photovoltaic junction boxes, in particular to a solar junction box with aging resistance. Background Art

[0002] The solar junction box belongs to a kind of connector, mainly used for connecting solar panels and solar charge controllers, and is one of the important components in the solar system. By connecting relevant circuits inside the junction box, the circuit can be protected from external interference.

[0003] When the solar junction box is in use, it will be installed outside the solar panel and directly fixed during use. There is no additional protective structure installed outside the junction box. Since the solar junction box is directly exposed to the environment during installation, it will be eroded by external environmental factors such as rainwater and moisture during use. These environmental factors can accelerate the aging of the solar junction box and affect the normal use of the solar box. To solve this technical problem, the utility model proposes a solar junction box with aging resistance. Content of the Utility Model

[0009] Preferably, two groups of the rotating rod and the clamping plate are arranged up and down and are symmetric with each other. The outer surface of the connecting wire is in contact with the inside of the clamping plate.

[0010] Preferably, a support rod is fixedly installed on the outer surface of the rotating rod, a spring is sleeved outside the support rod, and both ends of the spring are fixedly installed on the outer surfaces of the upper and lower rotating rods.

[0011] Preferably, a connecting plate is fixedly installed on the outer surface of the clamping plate. A positioning hole is formed inside the connecting plate. A positioning plate is fixedly installed on one side of the connecting plate. The outer surface of the positioning plate is slidably connected to the inside of the positioning hole.

[0014] In the utility model, through components such as the spring and the positioning plate, under the pulling of the spring, the upper and lower clamping plates can be controlled to approach, and the clamping plates can be controlled to be tightly attached to fix the connecting wire. When in use, it is convenient to quickly fix the position of the connecting wire part. During installation, the positioning plate can enter the inside of the positioning hole. Relying on the connection between the positioning plate and the positioning hole, the connecting plates on the left and right sides can be positioned, preventing the clamping plate from tilting during fixing and causing gaps at the connecting wire sealing part, ensuring the stability during use.
