458407-9 is a crimping tool accessory made by AMP/TE Connectivity, a worldwide manufacturer of connectors, components and accessories for electronic and electrical systems. It is used in combination with other crimping tools to properly crimp terminals, splices and lugs. It also has fields of application and a working principle.

Fields of Application

The 458407-9 can be used with AMP, Raychem or Raychem-ring type terminal lugs, splices, and harnesses. It is designed for ring-tongue style crimps that are crimped with DIN 46228-4 Class 1 style of crimp. The 458407-9 is also a great choice for stripping round and flat wires quickly, safely, and with little effort.

This accessory can be used in any type of application that requires precise and repeatable crimps. It is suitable for crimping 0.2 - 2.5 mm2 stranded copper conductors, and can also be used with steel or aluminum wire. The soft touch grips provide excellent comfort and control for the operator, making it very user-friendly.

The 458407-9 is a great choice for applications in which extreme vibration or temperature changes are present, due to its shock-resistant frame that absorbs the vibrations and temperature variations and maintains consistent crimp quality. It is also very lightweight at only 170 grams, making it easy to carry around with minimal fatigue on the user\'s part.

Working Principle​

The 458407-9 works by a process of hydraulic crimping. This is achieved by placing the wire and terminal lug in the jaws of the tool. Once the jaws are closed, a hydraulic ram makes contact with the terminal lug, applying pressure to the wire and terminal. This pressure causes the wire and terminal to be crimped together, creating a secure and lasting connection.

The hydraulic ram in the 458407-9 is connected to a trigger release, which is then operated by the operator. The trigger releases the hydraulic pressure from the terminal, and then the jaws of the tool can be opened to release the crimped wire and terminal. The crimped connection is then completed.

The 458407-9 is designed to achieve high-quality, repeatable crimps with precise crimp tolerances and a perfect finish. It also features a self-eject mechanism which ejects the terminals from the tool automatically once the crimping process is complete. This allows the operator to easily switch between different sizes of terminals.

Conclusion

The 458407-9 is a great accessory for any application in which precise and repeatable crimps are needed. Its ability to quickly, safely and effectively crimp wires and terminals makes it an ideal choice for a wide variety of applications. It has been designed to provide high-quality crimps and a perfect finish, and its self-eject mechanism makes it easy to switch between different sized terminals. It is also lightweight and shock resistant, making it highly suitable for applications where vibration or temperature changes are present.
