Terminals – quick connects, quick disconnect connectors – are widely used in a variety of applications, but their 63646-2 application field and working principles are a particular set of standards that provide rigorous guidelines for safety and longevity. Each application field is associated with a specific type of terminal, and the principles of the 63646-2 standard cover the appropriate specifications that need to be met for each scenario.

Terminals and Connectors Types

It is important to choose the appropriate terminal for each application field, using the guidance from the 63646-2 standard. Generally, the most common types of terminals and connectors used are:

• Crimp ring terminals: These are crimped to a wire or device to make a sound connection. There are different size terminals available, and the force needed to be applied during the crimping process can vary.
• Solder cup terminals: made for permanent connections, these terminals require soldering to connect the wire to the device.
• Quick-connect terminals: Providing a convenient way to connect and disconnect wires, this type of terminal is most commonly used in mobile devices and temporary wiring.
• Wire spiral for fastening: A simple wind-up type connection that uses a metal coil to hold the wiring. This type of terminal is often used in motors and other circuits that require rapid connection and disconnection.
• Cable clamp terminal: Used to protect and keep the wiring secure, this type of terminal is often used in vehicles and machinery.

63646-2 Application Fields and Working Principles

The 63646-2 standard is used in the electrical industry to ensure that the safety, durability and quality of the terminals and connectors used in any application field is valid. This standard covers installation, measurement, testing, and maintenance of terminals, quick connect and ball bearing devices. The principles are meant to provide guidance on using the appropriate type of terminal for a given application and extending the lifespan of the terminal.

Installation

When installing terminals, it is important to ensure that all connections are correctly electrically terminated and firmly secured. The terminal should fit snugly in the housing without any loose parts. Any excess wire should be stripped, cleanly and securely. During the installation process, it is important to consider the short and long-term stresses that will be placed on the terminal, which calls for an appropriate gauge of the terminal. The contacts should also be selected to meet the required electrical conditions.

Measurement

Having the correct measurements for all terminals is essential to ensure optimum performance and safety. It is important to measure the length, overall width, width between connector posts, conductor size supported, and voltage and current capacity of the terminal. It is also important to consider environmental factors when selecting the appropriate terminal and to have a good understanding of the application field that the terminal will be used in.

Testing and Maintenance

Once a terminal is installed, it is important to ensure that it is tested for any potential defects and that it meets the safety and longevity requirements of the application field. In addition, the 63646-2 standard provides guidance on how to properly maintain terminals. Maintenance includes visual inspections, cleaning, and tightening of screws when necessary.

Conclusion

Terminals and connectors have numerous applications and a range of types to choose from. The 63646-2 standard provides the necessary guidance to ensure the safety and longevity of the terminal installation. This standard outlines the appropriate installation, measurement, testing, and maintenance procedures that should be followed in order to get the most out of a terminal or connector.
