Solar energy wiring box with reliable connection

Abstract

The invention relates to a solar energy wiring box with reliable connection in the solar energy technology field. The solar energy wiring box comprises a wiring box body and a wiring box cover covering the wiring box body in pair. A positive electrode joint and a positive electrode joint are arranged at the front end of the wiring box body, and a cross beam formed through integration with the wiring box body is arranged in the holding cavity. Three metal wiring posts and two diodes are fixed on the cross beam through bolt connection. The front ends of the first wiring post and the third wiring post are external wiring ends, and the external wiring ends have hollow cylindrical structures. The positive electrode joint and the positive electrode joint comprise a plastic nut and a gold plating guide pillar respectively. Elastic nets sleeves the front end and the rear end of the gold plating guide pillar. Two ends of each elastic net are clamped on the surface of the gold plating guide pillar tightly. The middle end of each elastic net is composed of a plurality of protruded arc-shaped elastic sheets. Through design of the positive electrode joint and the positive electrode joint with gold plating guide pillars, the connection process is convenient and simple, tight connection can be achieved after direct insertion, any loosening phenomenon cannot happen, and passing of a large current can be ensured.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar junction box with reliable connection. Background technique [0002] Solar energy is an inexhaustible clean energy source. The use of solar panels to generate electricity has become popular. As a very important component on solar panels, solar junction boxes have achieved certain innovations and optimizations with the efforts of countless technicians. But the traditional solar junction box also has the following defects: 1) the connection between the connecting column and the external cable is only fixed by simple welding, and the reliability is not strong after the connection; 2) the method of fixing the connection by welding or other screws will This leads to inconvenient installation, and cannot effectively achieve tight connection, resulting in poor contact and affecting the stability of current transmission.
