Abstract

The invention discloses a connecting assembly of a solar photovoltaic cell junction box, which is characterized in that the connector assembly is in an integrated structure and comprises a diode inserting frame, a cable wiring port and a refluxing strip connecting port, wherein the cable wiring port and the refluxing strip connecting port are integrated with the diode inserting frame; the diode inserting frame is positioned between the cable wiring port and the refluxing strip connecting port; a diode inserting port is arranged in the diode inserting frame; and the diode inserting port is a hollow cylinder formed by oppositely folding and turning a copper piece (sheet) with two semicircular concave surfaces. In the invention, because the connector assembly is changed from combination into integration of a plurality of parts and the connection between the inserting port and each diode pin is changed from line contact or point contact into surface contact, and the connector assembly has the advantages of small current resistance, high transmission efficiency, simple machining and installing processes, low consumption of copper product resources and low production cost.

Description

technical field [0001] The invention relates to a photovoltaic cell, in particular to an improvement of the structure of a connector inside a photovoltaic cell junction box. Background technique [0002] Solar energy is a clean and renewable energy that is inexhaustible. Solar photovoltaic cells are one of the most efficient ways to harness the power of the sun to generate electricity. The junction box in the solar photovoltaic cell is the intermediate link of the solar photovoltaic cell, and is connected to the diode through the connector in the junction box. The connector of the prior art is realized by combining three or more parts. Due to the many contact points of the connector, the current resistance increases and the loss is large, so that the current of the solar panel cannot be effectively transmitted, which affects the effective use of power; at the same time, the copper consumption of the connector is large, the production and installation process is complicated...
