Crimp tools are used to secure wires into electrical connectors and fittings. The crimping is often done with a wire crimper, which applies pressure to the wire, usually with a pair of tongs or jaws, to firmly insert it into the connector. The 457266-3 is a widely-used crimp tool, and its application field and working principle are as follows.

Application Field

The 457266-3 is a dual-action crimping tool for use with solid terminal pins, and is designed for high-speed manual operations. This crimp tool can accommodate a range of wire gauges, including 0.3 – 6.5mm² and 8 – 28 AWG. It is suitable for larger volumes of production for both insulated and non-insulated solid terminals. It is widely used in aviation, automotive, electronics, instrumentation, medical, and telecom industries.

Working Principle

The 457266-3 uses a two-stage crimping technique. In the first stage, pressure is applied to the wire in order to compress it and form a complete contact with the terminal. This ensures that the resistance of the electrical contact is minimized. Then, in the second stage, the crimp tool applies a rotational force to the wire in order to securely fasten it to the terminal. This ensures that the wire is unable to move or become detached from the terminal, ensuring a reliable electrical connection.

Conclusion

The 457266-3 is a popular and versatile dual-action crimp tool, designed for fast and reliable connections of solid terminals. It is used in a wide range of industries, from aviation to automotive and electronics. This crimp tool is a reliable and cost-effective way to ensure that wires are securely connected and that electrical contacts are minimized.
