Ring connectors, also known as ring terminals, are commonly used for electronic cable assemblies of chemical equipment. They are the most popular type of terminal, and are essential components in any electrical system, providing a secure connection for a variety of standard and custom-specified applications. In this article, we will discuss the 63446-2 application field and working principle of ring connectors.

Overview of the 63446-2 Application Field

The 63446-2 specification is a standard for ring terminals used widely in the chemical equipment and industrial market. It is designed to single screw, nominal 0.063 inch terminal size, and also includes terminal-to-wire gauge size requirements for the crimp connection. The specification covers ring terminals that have threaded centres, also known as eyelets, insulated barrels, or other types of terminal devices that are crimped or welded onto the end of cables. These terminals are widely used in the manufacture of various electrical components, including switches, circuit breakers, audio and video cables, automotive wiring assemblies, and more.

How Does a 63446-2 Terminal Work?

A 63446-2 terminal works through a two-part connection between the terminal and the wire. The first step is to make sure the wire size meets the gauge size specification of the terminal. Next, the terminal is placed in the appropriate terminal connector, such as a butt splice or an open barrel. Then, the strands of the wire are clamped with a special crimping tool. This provides a secure mechanical and electrical connection between the terminal and the wire. Finally, the terminal is screwed into its end-position, which completes the connection.

Advantages of 63446-2 Terminals

There are several advantages to using 63446-2 terminals. First, the terminal is designed to provide a secure and reliable connection which does not become loose over time. In addition, the terminals are easy to install, and can be crimped in place without the need for solder or adhesive. The terminals also feature a wide range of size, colour and insulation options, allowing the user to select the most appropriate combination for the application. Furthermore, the terminals are RoHS compliant and are designed to meet the latest environmental standards.

Disadvantages of 63446-2 Terminals

There are a few drawbacks to using 63446-2 terminals. As mentioned earlier, the terminals must meet a specific wire size requirement in order to provide a secure connection. If the wrong wire size is used, the terminal will not be adequate for the application. Due to the fact that the terminals are not self-locking, they also require a screw to secure them in place, which can add time and complexity to installation. Finally, although the terminals are RoHS compliant, they are not UL-certified; therefore, they should only be used in non-life-critical applications.

Conclusion

The 63446-2 specification is a widely used standard for ring terminals in the chemical equipment and industrial markets. The terminals provide a secure mechanical and electrical connection between the wire and the terminal, and feature a wide range of size, colour and insulation options. However, it is important to make sure the wire size meets the gauge size requirement of the terminal, and that it is only used in non-life-critical applications. In conclusion, ring connectors are a reliable and cost-effective option for many electronic cable assemblies.
