Terminals - Ring Connectors are widely used in various industrial areas because of their simplicity and reliability. The 3456 and 7 connectors are two of the most popular types of terminals, and they have specific uses. In this article, we will take a look at their applications and working principles.

3456 Connectors

The 3456 connector is designed to provide reliable electrical connections in high voltage applications. It is most commonly used to connect large, robust electrical components, such as transformers and capacitors. The contact housings of the 3456 connector are rated for 600V and have a maximum operating voltage of 400V. The connector also has a current rating of 30A, making it an ideal choice for high-voltage applications.

The 3456 connector is also used in low voltage applications and can be found in control panels,industrial control systems and buildings management systems. It comes in several sizes and can be configured with a variety of pin configurations. Additionally, it is flame-retardant and has an IPX7 protection rating, making it resistant to water and dust.

7 Connectors

The 7 connector is similar to the 3456 connector in that it is designed to provide reliable electrical connections in high voltage applications. However, the contact housings of the 7 connector are rated for up to 300V and have a maximum operating voltage of 250V. The current rating for this type of connector is 15A. It is typically used for lower power applications, such as lighting control, instrumentation and building automation.

The 7 connector also has several optional features that can be included. These include single-core, dual-core and triple-core pins, different pin configurations, and various sealing and termination options. Additionally, it is rated as IP2X for dust and water, making it suitable for industrial environments.

Working Principle

The working principle of the 3456 and 7 connectors is straightforward. The contact housings of these terminals are designed to connect two electrical components and provide reliable electrical connections. The components are held in place by the contact housings, which are connected to one another through a series of pins. The pins are insulated with insulation material to ensure that there is no risk of electric shock or any other adverse effects.

The pins themselves are made from metal and can be configured in various ways depending on the application. For example, the pins may be arranged in a straight line, in a star configuration, or in a rectangular pattern. Additionally, the material of the pins can range from copper to brass, and the contact housings can be made from various materials such as polymeric or plastic.

The terminals are also designed to be vibration-resistant and able to withstand extreme temperatures. This is achieved through the material of the pins and contact housings, as well as the insulation material. Additionally, the terminals are designed to provide electrical insulation when mated, meaning that electricity will only flow from one terminal to another when they are connected.

Conclusion

3456 and 7 connectors are popular for their reliable electrical connections and various applications. They provide a secure and reliable connection between two electrical components, and they are also resistant to water and dust. Additionally, these terminals are simple to use and versatile, making them a great choice for high-voltage and low-voltage applications. Hopefully, this article has provided some insight into the uses and working principles of the 3456 and 7 connectors.
