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 in the shape of a "C" with an upward opening, an engaging groove 6 at the bottom, and a through hole 7 on both sides of the opening on the upper surface. 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 bottom of the storage hole 2 has a snap hook 3, and the opening direction of the snap hook 3 is parallel to the opening direction of the side of the storage hole 2; The inner wall of the pocket 2 is provided with a friction edge 9 .

[0019] see figure 1 and Figure 4 , the metal conductive sheet 1 and the clip spring 5 are installed in the box body 8. When assembling, the clip spring 5 is pushed into the accommodating hole 2 from the side of the opening of the engaging hook 3, and the engaging groove 6 is aligned with the engaging hook. At this time The engaging hook 3 hooks the engaging groove 6 of the clip spring 5 so that the clip spring 5 is fixed in t...

Embodiment 2

[0021] see Figure 5 , different from Embodiment 1, there is a flanging 4 between the upper opening of the circlip 5 and the through holes 7 on both sides. 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 a through hole, and the bottom of the opening is provided with a clamping groove; 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 of the holding hole of the metal electric conduction sheet is provided with a clamping hook, which is matched with the clamping groove of the clamping spring. 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...
