Photovoltaic Connectors: 1971131-4 Application Field and Working Principle

Photovoltaic connectors, also known as solar connectors, are crucial in connecting photovoltaic modules to other similar components in solar energy systems. Photovoltaic connectors are designed to operate under severe environmental conditions, such as weathers, temperatures, solar radiation, humidity and so on. Since 1973, connectors for PV modules have changed dramatically and are now commonly used in the solar energy industry. The Solar Panel Connectors Model No. 1971131-4 are the latest type of solar connectors on the market, which is designed for photovoltaic array connection, so as to ensure the utility scale solar projects running safely and effectively. These connectors fulfill IEC 61215 and IEC 61730 safety standards, and are applied to the string type, disconnected type or hybrid type of solar power station.

What is 1971131-4?

The Solar Panel Connectors Model No. 1971131-4 is a plug-and-socket type, spring loaded, waterproof and reliable photovoltaic connectors, which offers safe, one-handed and concurrent connections, and the locking system provides a high reliability bare copper contact between plug-and-socket pairs. 1971131-4 connectors conform to different safety standards, such as the 1000V DC IEC 61215 Standard and the 2000V DC IEC 61730 Standard. They offer matching options for various conditions, with a broad range of sizes to fit with various solar power systems. They are especially designed for large solar panel fields, offering the highest service life and reliable working environment.

Benefits

The Solar Panel Connectors Model No. 1971131-4 is designed for large solar power stations for various benefits. First, it is waterproof, dustproof and salt-mist proof, which means it can offer a high standard of protection to the system. Second, it can be used for both indoor and outdoor applications, and it is easy to use and install. Third, it is anti-aging, sunlight-resistant, and provide high current rating, which makes it a more reliable, efficient and durable choice. Last but not least, it offers reliable, safe, one-handed and concurrent connections, which ensures the utility scale solar projects running safely and effectively.

Working Principle

The Model No. 1971131-4 connector has two contact points, plug and socket. The plug is pre-loaded into the socket, and the contact is made with a double claw locking mechanism. Once inserted, the plug is firmly locked inside the socket and provides electrical continuity. The contact is made with the bare copper strip, which is resistant to corrosion and oxidation. The plug has an inner and an outer plate, and the socket has an outer and a contact plate. When the plug is inserted, the outer plate of the plug is connected to the contact plate of the socket and the inner plate of the plug is connected to the outer plate of the socket. This connection ensures highly reliable electrical connections and prevents accidental disconnects.To sum up, 1971131-4 solar panel connectors are the most reliable connectors for string type, disconnected type or hybrid type of solar power plants, which provide high reliability, wide environmental adaptability and a sure waterproof. It is dustproof, salt-mist proof, anti-aging, sunlight-resistant, easy to install and offers a reliable service life. This Solar Panel Connector Model No. 1971131-4 is the ideal choice for either residential or utility scale solar projects.
