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 retaining spring 5 is "C" shaped with an upward opening, and a through hole 7 is respectively provided 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 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. During use, only need to use tools, such as pliers, insert the two through holes 7 on the circlip 5 and clamp them...

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 rapid junction box, which comprises a box body; a metal conductive sheet and a clamp spring are arranged in the box body; the section of the clamp spring is C-shaped with an upward opening; a through hole is arranged at each of the two sides of the opening respectively; one end of the metal conductive sheet is bent to form a holding hole corresponding to the clamp spring; and a movable buckle that can be opened and closed is arranged at each of the two lateral sides of the bottom of the hollow hole of the metal conductive sheet respectively. The rapid junction box is convenient to manufacture, and simple to insert bus bar, along with good wiring effect.

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...
