Terminals - Ring Connectors

31114, also known as ring connectors, is a type of electrical connectors commonly used in wiring installations. They are designed to hold conductors stead and provide reliable electrical connections. The connectors are made from metal and feature an insulated plastic sleeve to provide extra insulation and protect against shorts and arcing. They come in a range of sizes to fit various cable diameters.

Application Field

31114 connectors are most commonly used in automotive and household wiring applications. They are used to secure wiring in automobiles, boats, and other motor vehicles. For household applications, they are also used to secure wiring for outdoor lighting, along with other electrical appliances such as a microwave, ovens, refrigerators, dishwashers, and dryers. Generally, the larger sizes, 5-9 mm, are more commonly used in industrial applications such as in large-scale buildings, while the smaller sizes, 2.5-4mm, are used for general household wiring.

Working Principle

31114 connectors feature an inner and outer sleeve made from metal. The two sleeves fit together via interlocking and compressed spring fittings which secure the connection. As the sleeves fit, the inner sleeve slides and expands outward, gripping the wire. This ensures the conductor is secure and will remain secure even after multiple uses. It also ensures a good electrical connection, as the conductive material is in contact with the metallic surfaces of the connectors.

Typically, 31114 connectors come pre-insulated with an injected plastic or vinyl sleeve, offering extra insulation from external electrical sources and additional protection against short circuiting. The insulation significantly reduces the risk of arcing. It is also commonly used in conjunction with heat-shrink tubing, providing an additional layer of insulation and strain relief due to its insulating properties.

Conclusion

Overall, 31114 connectors are reliable and easy to use in a variety of electrical wiring applications. Their simple design and the pre-insulated plastic sleeve make it easy to install and fast to use. The interlocking and compressed spring fittings feature ensures a secure connection and better protection against shorts and arcing. Both the small and large sizes are suitable for use in automotive and household applications, as well as in larger scale industrial buildings.
