Terminal and connector for photovoltaic module connector

Abstract

The invention provides a terminal for a photovoltaic module connector. The terminal is used for a module connector of a photovoltaic system with voltage output of 1500V or above. The terminal for the connector comprises a contact pin and a plug sleeve, wherein each of the contact pin and the plug sleeve comprises a riveting part, a connecting and fixing part and a plugging part; each riveting part is fixedly connected with a plastic shell of the connector; each connecting and fixing part is provided with a plurality of wedge bump structures and is fixed to a lock catch structure in the connector; the length of the riveting part of the contact pin is 4.0+ / -0.5mm and the total length is 24.8+ / -1mm; and the length of the riveting part of the plug sleeve is 4.0+ / -0.5mm and the total length is 28.76+ / -1mm. The invention further provides the connector with the terminal. According to the connector, the resistance is low and the work calorific value is small on the basis of meeting the security requirements of an electric clearance and a creep distance; and a more serious accident of the photovoltaic system due to the fact that the connector is burnt out by a high temperature generated at work is avoided.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a terminal for a connector of a photovoltaic system component applied to a voltage output of 1500V and above and a connector with the terminal. Background technique [0002] With the global climate change and the increasingly severe environmental pollution caused by traditional fossil energy, the green and renewable energy industry has developed rapidly in the past ten years. Solar energy is a renewable resource, and the solar cell technology that uses the photovoltaic effect to generate electricity has attracted worldwide attention. Solar cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium selenide copper and other materials, which can convert light energy into electrical energy. At present, photovoltaic modules composed of multiple solar cells are widely used to build various photovoltaic power generation s...

Problems solved by technology

[0003] The photovoltaic power generation system needs to connect multiple photovoltaic modules to each other through cables to form a photovoltaic module array and then output a large voltage to the outside, and the electrical connector is an indispensable device for the interconnection of photovoltaic modules. The male plug and female plug of the connector There are conductive copper terminals in the electrical connector. At present, the design of the copper terminals in the electrical connector is mainly based on the requirements of electrical safety, that is, to meet a certain electrical clearance and creepage distance, and lack other details. to consider

For photovoltaic module connectors used for 1500V and above or even higher voltage output, it is also necessary to consider the safety risk caused by the heat of the connector itself. For example, when the copper terminal in the connector is too long, its resistance will increase. If it increases, more heat will be generated, which will easily burn out the connector, which will affect the safe use of the entire photovoltaic module and photovoltaic array
