Embodiment 1

[0032] Such as Figure 1-3 As shown, the heat-dissipating split junction box for solar modules of the present invention includes a negative terminal box 10, an intermediate terminal box 20, and a positive terminal box 30 that are independent of each other, and the intermediate terminal box 20 is arranged between the negative terminal box 10 and the positive terminal box. Between the boxes 30, the negative wire box 10 is connected to the negative pole of the photovoltaic connector, and the positive wire box 30 is connected to the positive pole of the photovoltaic connector. Each wire box includes a box body 1 and a box cover that can close the box body. At the starting end of the negative electrode of the module, there is only one terminal 3 for connecting the lead wire 2 of the module, and the terminal 3 is connected to the negative terminal of the photovoltaic connector through the cable 103 at the same time; the positive terminal box 30 is arranged on the solar cell module A...

Embodiment 2

[0035] Such as Figure 4-6 As shown, the difference between this embodiment and Embodiment 1 is that the bypass diode 4 is located on one side of the terminal 3. For the convenience of description, the two conductors are named as the first conductor 6 and the second conductor 6 here. Conductor 7, the two ends of the first conductor 6 are bent to form two first connecting parts 6a parallel to the second conductor 7, and a transverse direction is formed between the two first connecting parts 6a and the second conductor 7 Two connection bits 5 are distributed, so that the bypass diode 4 and the terminal post 3 are horizontally arranged side by side. The second conductor 7 is located between the two first connection portions 6 a of the first conductor, and two second connection portions 7 a connected to the first connection portions 6 a are formed on the second conductor 7 .

[0036] In this embodiment, the arrangement of the bypass diodes and the binding posts connected to the lea...

Embodiment 3

[0038] Such as Figure 7 As shown, another aspect of the present invention provides a solar cell module 100 using the heat dissipation type split junction box for the solar module, including several double-sided battery sheets 101, upper glass and transparent backplane or glass, and the battery sheet They are connected through interconnection bars and bus bars 102 and are connected to the terminal post 3 of the heat-dissipating split junction box for solar modules through component lead-out lines. Several battery pieces 101 are vertically divided into groups. In this embodiment, each The module includes 60 double-sided battery pieces, and the battery pieces are divided into 6 groups longitudinally, and each group includes 10 double-sided battery pieces 101. The solar modules are connected by a heat dissipation split junction box, an intermediate junction box 20 is connected in the middle of every two groups of cells, and the edges of a group of cells on both sides of the modul...

Abstract

The invention discloses a heat-dissipation split-type conjunction box used for a solar assembly. The heat-dissipation split-type conjunction box comprises a cathode wire box, intermediate wire boxes and an anode wire box which are mutually independent. The intermediate wire boxes are arranged between the cathode wire box and the anode wire box, and each wire box comprises a box body and a box cover which is capable of covering the box body. The heat-dissipation split-type conjunction box is characterized in that the cathode wire box is arranged at a cathode initiating terminal of the solar cell assembly, the box body is only internally provided with one binding post used for being connected with an assembly leading-out wire, and the binding post is simultaneously connected with a cathode terminal of a photovoltaic connector through a cable; the anode wire box is arranged at an anode initiating terminal of the solar cell assembly, the box body is only internally provided with one binding post used for being connected with an assembly leading-out wire, and the binding post is simultaneously connected with an anode terminal of the photovoltaic connector through a cable; and the number of the intermediate wire boxes is three. In addition, the invention further discloses the solar cell assembly using the heat-dissipation split-type conjunction box used for the solar assembly.

Description

technical field [0001] The invention relates to a junction box, in particular to a heat dissipation split junction box for a solar module and a solar cell module thereof, which belong to the technical field of solar modules. Background technique [0002] The solar junction box is the connector between the solar battery array and the solar battery charging control device.
