Embodiment Construction

[0021] Figure 1 is There are four terminal and three diode implementations.

[0022] exist Figure 1 , two cables ⑧ are respectively locked by two fixing rings ⑥, respectively connected to the rear ends of the two terminals ④. Insert the fixing ring ⑥ into the limiting groove inside the box body ①, and use the screw ③ to press the cable ⑧ onto the junction box through the pressing block ⑦. A diode ② soldered to the front end of the terminal ④ connected to the cable, and then soldered to the front end of the other terminal ④. If only two terminals ④ are installed inside the junction box, only one diode ② is needed to connect the two terminals ④ in series; if three terminals ④ are installed inside the junction box, two diodes ② are needed to connect the three terminals ④ The terminals ④ are connected, and the terminal ④ with the cable ⑧ is only connected to a diode ②, and there are two diodes ② welded on the terminal ④ without the cable ⑧ in the middle of the two terminals ④ ...

Abstract

The invention provides a special junction box for a solar module, which is used for electrical installation of the solar module and can ensure reliable operation of the solar module. The special junction box is characterized in that a fixed ring is added to the box for locking a connecting cable so as to really realize separation of mechanical connection and electrical connection; tables for installing diodes are arranged on the box and a box cover respectively so that the diodes can be directly contacted with the box and the box cover, which shortens the radiating path of the diodes and improves heat dissipation of the diodes; radiating fins are arranged on the box cover, which increases radiating area of the box cover; and steps are arranged at the bottom of the box and are used for limiting relative position between the junction box and a conductor at a lead-out terminal of the solar module so as to further limit installation location.

Description

Technical field [0001] The invention is a special junction box for solar battery components, which is used for electrical installation of solar battery components and ensures reliable operation of solar battery components. Background technique [0002] A solar cell module is a photovoltaic power generation device that encapsulates and assembles series or parallel solar cells to achieve a certain mechanical and electrical stability and is easy to install and use. The power output of the solar cell module requires the use of a junction box that can be connected to an external circuit. At the same time, the junction box should also have the ability to make the solar cell module work under abnormal conditions. [0003] In order to ensure the ability of the solar cell module to work under abnormal conditions, a bypass diode is installed inside the junction box dedicated to the solar cell module. The function of the bypass diode is to enable the current flowing through the solar...
