Problems solved by technology

The disadvantage of this structure is: the number of parts is large, and the processing accuracy of any part is slightly flawed, which will affect the wiring effect; in addition, the vertical edge of the elastic sheet is attached to the inner surface of the outer vertical edge of the concave part of the conductive sheet, The free end of the elastic sheet is fixed to the outer vertical edge, so it is difficult to separate the vertical edge of the elastic sheet from the conductive sheet with a wedge tool

Embodiment 1

[0018] see figure 2 The circlip 5 is "C" shaped with an upward opening, and the two sides of the opening on the upper surface are respectively equipped with a flanging 4. see image 3 , the front end of the metal conductive sheet 1 has a storage hole 2, the size of which matches the circlip 5; the two sides of the bottom of the storage hole 2 each have a movable buckle 3 that can be opened and closed, and the opening and closing direction of the movable buckle 3 and the accommodation The opening direction of the side of the hole 2 is parallel;

[0019] see figure 1 and Figure 4 , the metal conductive sheet 1 and the circlip 5 are installed in the box body 8. When assembling, first open the movable buckle 3, push the circlip 5 into the accommodating hole 2 from one side, and then close the movable buckle 3 to fix the circlip 5 In the storage hole 2. When in use, just use tools, such as pliers, to clamp the two flanges 4 on the circlip 5, and there will be a gap between t...

Embodiment 2

[0021] see Figure 5 , different from Example 1, there is a through hole 7 besides the flange 4 on both sides of the opening of the upper end of the clip spring 5. In use, in addition to clamping the clip spring 5 through the flange 4, it can also be clamped through the through hole 7. Tighten the circlip 5.

Abstract

The invention discloses a quick junction box. The quick junction box comprises a box body, wherein a metal electric conduction sheet and a clamping spring are arranged in the box body; the section of the clamping spring is in a C shape with an upward opening; two sides of the opening are respectively provided with an upward turned-over edge; one end of the metal electric conduction sheet is bent to form a holding hole corresponding to the clamping spring, and the clamping spring is located in the holding hole; and bottom two sides of the holding hole of the metal electric conduction sheet are respectively provided with an openable moving buckle. The quick junction box has the advantages that the manufacture is convenient, the operation of inserting omnibus bar is simple and the junction effect is good.

Description

technical field [0001] The invention relates to a quick junction box, which comprises a box body, and a metal conductive sheet and a retaining spring are arranged in the box body. Background technique [0002] As the application of solar power generation becomes more and more common, the junction boxes closely related to its application are constantly being introduced. Solar power generation uses multiple sets of solar cell modules arranged in a matrix to convert light energy into electrical energy. Each set of solar cell modules and wiring The box is connected, and the junction box is connected with other parts of the solar power generation system. Since the junction box works outdoors for a long time, the rationality and quality of the mechanical structure design are directly related to the efficiency of power transmission. [0003] The solar battery module is connected with the junction box through the bus bar, and the firmness of the connection between the two directly a...
