Photovoltaic anti-reflection diode

Abstract

The invention provides a photovoltaic anti-reflection diode. The photovoltaic anti-reflection diode is characterized by comprising a package body, an anode connector and a cathode connector, wherein the package body comprises a shell and at least two diode chips; the at least two diode chips are arranged in the shell; anodes of the diode chips are connected into a whole through a connecting bridge; the connecting bridge is provided with an anode terminal; the anode terminal is arranged at the upper part of the connecting bridge; elastic connection of the anode terminal and the connecting bridge is achieved through an elastic bending part; the anode connector is led out from the side surface of the package body and is connected to the anode terminal; the cathodes of the diode chips form independent cathode terminals respectively; the cathode connector is led out from the side surface of the package body; the cathode connector is connected to the cathode terminals; fastening components which are fastened to and fixedly connected with a photovoltaic combiner box and a photovoltaic module are arranged at the end parts of the anode connector and the cathode connector; and a radiating base is fixedly arranged at the bottom part of the shell. The photovoltaic anti-reflection diode can achieve quick installation and fault detection, and has a relatively small size.

Description

technical field [0001] The invention relates to the field of diodes, in particular to a photovoltaic anti-reverse diode. Background technique [0002] With the rapid development of the photovoltaic industry, solar modules have higher and higher requirements on the cooling capacity and service life of photovoltaic diodes. Photovoltaic diodes currently on the market generally include a package body. A plurality of terminal posts with fixed nuts are placed on the package body. The terminal posts are exposed outside the package body, and then the connection between the photovoltaic combiner box and the photovoltaic module is realized through the terminal posts; Heat dissipation metal sheets are installed at the bottom; in order to avoid being affected by the external environment, the photovoltaic diodes are generally placed in the photovoltaic combiner box during installation, but due to the long-term use of the photovoltaic combiner box, affected by its structure, it is easy fo...

AI Technical Summary

Problems solved by technology

Due to the large number of connection terminals on the photovoltaic combiner box and photovoltaic modules, the installation of such a structure needs to be installed one by one, which is too time-consuming, and once a fault occurs, it needs to be checked and repaired one by one, which affects the maintenance efficiency
