Embodiment Construction

[0020] see figure 1 and figure 2 and image 3 One side of the head of the metal connecting piece 3 is provided with a first through hole 4 , and the other side is provided with a second through hole 1 and a third through hole 2 . The metal connecting piece 3 includes a head front wall 14 , a head rear wall 15 , a tail end 16 and a support end 10 .

[0021] see Figure 4 and Figure 5 , The short end of the elastic piece 5 has a hook 13, and the long end has a fourth through hole 6.

[0022] see Figure 6 and Figure 7 , the long end of the elastic piece 5 passes through the first through hole 4 of the metal connecting piece 3 and extends into the head of the metal connecting piece 3 until the elastic piece 5 can no longer be inserted, and the round end of the elastic piece 5 touches the metal connecting piece 3, At this time, the long end of the elastic sheet 5 was tightly pressed on the head front wall 14 of the metal connecting sheet 3, as can be seen from the figure...

Abstract

The invention discloses a solar battery junction box, which comprises a box body and a bus bar connecting device. The bus bar connecting device is composed of a connecting piece and an elastic piece. The longitudinal section of the connecting piece is "q" shaped, and its head The part is put into the accommodation hole at the bottom of the box body, the side close to the bottom of the accommodation hole has a first through hole, and the side away from the bottom of the accommodation hole has a second through hole and a third through hole; the elastic sheet It is "Ω" shape, and one end has a fourth through hole; the end of the elastic piece with the fourth through hole extends into the head of the connecting piece through the first through hole, and is placed in the accommodation hole at the bottom of the box together; At least a part of the fourth through hole and the third through hole overlap each other; the edge of the first through hole of the connecting sheet also has an upwardly tilted support end. The invention has only two main parts, which are plugged and matched with each other, has good interchangeability, and is also very simple and convenient to maintain.

Description

technical field [0001] The invention relates to a solar battery junction box, which includes a box body and a bus bar connection device. Background technique [0002] Solar cells are being used more and more widely because of their environmental protection. Usually, the current generated by the solar cell is transmitted to the subsequent power lines through the bus bar and the junction box connected to the bus bar. However, the current bus bar and the junction box are usually connected by a fixed connection. There will be a connection point in the fixed connection method, and the contact resistance at the connection point will consume the power generated by the battery, and because solar power generation has the characteristics of low voltage and high current, the connection point is prone to overheating, which will threaten the safety of the line. In addition, the junction box is fixedly connected to the bus bar. When any problem occurs in the bus bar or the junction box, ...
