Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0021] like figure 1 As shown, the intelligent junction box of the present invention includes a box body 1 and a cover body (not shown). The inside of the box body 1 is provided with an accommodating cavity 8 and a number of cooling fins 2 laid on the bottom surface of the accommodating cavity 8 and arranged side by side. In this embodiment, the cooling fins 2 are thin copper sheets. Of course, other metal materials with good heat dissipation effects can also be used. . Diodes 3 are placed between adjacent heat sinks 2, and each diode 3 is provided with two pins, one of which is in contact with a heat sink 2, and ...

Abstract

The invention provides an intelligent junction box. The intelligent junction box comprises a box body which is provided with a containing cavity, wherein a plurality of cooling fins and diodes are arranged in the containing cavity, the cooling fins are arranged in an abreast mode, the diodes are arranged between every two adjacent cooling fins, each diode is provided with a pin which contacts the adjacent cooling fins, and one end of each cooling fin is connected with a metal sheet. The intelligent junction box further comprises a plastic block, wherein the plastic block is connected with the metal sheet in a press mode, and is clamped with the side portion of the box body. Due to the facts that the plastic block is connected with the metal sheet in the press mode, and is clamped with the side portion of the box body, firm crimping can be guaranteed, and contact between the metal sheet and the cooling fins are enabled to be stable.

Description

technical field [0001] The invention relates to a junction box, in particular to a solar junction box. Background technique [0002] At present, the solar junction boxes on the market are generally provided with diodes, and the function of the diodes is to prevent hot spots from being generated when the solar cell modules are partially shaded. If the diode is damaged, the junction box will not work properly, so the diode is connected with a thin copper plate to dissipate heat to the greatest extent. Metal sheets are connected to one side of the copper plate and connected by spring clips, which can ensure that all metal sheets and copper sheets are firmly fixed. However, the elasticity of the spring will become weak due to long-term use, and the metal sheet cannot be well clamped, which eventually leads to the separation of the metal sheet and the copper sheet, resulting in poor electrical contact. [0003] Therefore, it is necessary to provide an intelligent junction box t...
