19544-1 refers to an international standard for crimping of electrical terminations mainly on the cables and conductors. This is used mainly in the manufacturing and electrical equipment installation sector for connecting two or more wires securely. Having a tight and strong electrical connection is essential to link different electrical components. It is also necessary to ensure that the connection works efficiently and lasts a lifetime.

This standard makes provision for crimping configuration, detail, performance, electrical testing and assembly. The requirements specified here are very important to ensure reliability of the electrical terminations and also improve the safety of the electrical installation.

Application Fields

The crimp tool of this standard is applicable for the electrical connectors and terminals used in construction sites, automotive industry, and manufacturing machines for inter-connecting wires and cables. It is also applicable in the audio-visual electronics and other electronic assembly fields.

Working Principle

The crimping tool consists of two main parts – the nose and the crimping die. The large, sharp nose holds the connector securely and also directs it to the crimping die. The crimping die is a set of two adjustable die jaws which pinch the negative and positive terminals of the electrical connector. The mechanical pressure applied is enabled by two threaded handles, one to the left of the jaws and other to the right.

The position of the dies are very important for creating the sufficient pressure for a reliable connection. When tightened, the crimping dies apply a uniform pressure which is applicable on both the terminals. A predetermined torque is necessary to ensure that a complete connection is made.

In addition, a depth setting gauge is also included on the tool for controlling the crimping depth. The depth setting gauge is adjustable according to the size and depth requirements of the electrical terminals.

The crimped electrical connector is also subjected to a variety of tests like current, voltage and continuous testing to make sure that the connection is reliable and safe.

By adhering to this international standard, users can be confident that their electrical connections are robust and can be used in harsh environments.
