Problems solved by technology

Usually, the bypass diodes are connected to the conductors of each phase by welding, the manufacturing process is complicated, the manufacturing efficiency is low, and the connection reliability is poor.
In addition, due to the large heat generated by the bypass diode during the operation of the junction box, the junction box with the traditional structure has poor heat dissipation capacity, which makes the temperature rise in the junction box higher during operation and reduces the operating reliability.

Abstract

The invention relates to a photovoltaic junction box structure used for a photovoltaic solar power generation system and especially relates to an axial diode photovoltaic junction box. The axial diode photovoltaic junction box comprises a box body. A bottom of the box body is provided with multiphase electric conductors. An electric conductor end portion is provided with a terminal. A bypass diode is connected between the conductors. The bypass diode is an axial diode and possesses a cylindrical pipe body and a pair of pins which are located on two ends of the pipe body and are coaxial with the pipe body. The pair of pins of the bypass diode are overlapped on the two conductors respectively and a radiator is pressed on the pins. The radiator is connected and fixed with the conductors through bolts. In the invention, the connection is firm and conductive contact is reliable; simultaneously welding operation is omitted and manufacturing efficiency is increased; the radiator is used to carry out heat dissipation on the diode and the conductors so that a heat dissipation capability is increased; a temperature rise is reduced; simultaneously the radiator is also taken as a fixation pressing component so that the structure is simplified and manufacturing is convenient.

Description

Technical field [0001] The invention relates to a photovoltaic junction box structure used in a photovoltaic solar power generation system, in particular to an axial diode photovoltaic junction box. Background technique [0002] The photovoltaic junction box is a component used for circuit tapping in a photovoltaic solar system. A common photovoltaic junction box includes a shell and a multi-phase conductor installed in the shell. A bypass diode is connected between the conductors of each phase. Generally, the bypass diode and the conductors of each phase are connected by welding, and the manufacturing process is complicated, the manufacturing efficiency is low, and the connection reliability is poor. In addition, since the bypass diode generates a large amount of heat during the operation of the junction box, the traditional structure of the junction box has a poor heat dissipation capacity, which results in a higher temperature rise in the junction box during operation and redu...
