61455-2 Connectors, Interconnects

61455-2 or IEC 61455-2 is the 2nd part of the series of IEC 61455 specifications for electrical contact connectors. This part of the IEC 61455 series applies to connectors and accessories used in control or signaling circuits of machines and devices for power operation. The main purpose of the standard is to enable interchangeability of contacts within a specific application field as a means of ensuring safety and proper functionality.

This part of the IEC 61455 applies to the connectors and their accessories used at the interface between cable and appliance. It applies to appliance inlet/outlet connections which are accessible or non-accessible by personnel. In other words, the conditions of insulation, current intensity, surge protection, ground continuity, shock protection and other conditions that could effect safety are all covered by this IEC 61455 part 2.

The general requirements of the IEC 61455-2 are applicable to all types of connectors used in this application field. Some of the requirements are specific to the type of connection and are related to sealing and strain relief. Other requirements relate to the dimensions, electrical wirings, continuous ground paths, protection against over-voltage, short-circuiting and breaking, and isothermal conditions.

The IEC 61455-2 defines the General Principles of Connector Usage, for example, the orientation and orientation with respect to other devices, the types of connection, the selection of contacts, the installation of contacts, the maintenance of contacts, the safety features of the source of the short-circuit current and the means of affixing the connector to the appliance. It also defines the Technical Principles of Connector Usage, including the evaluation of parameters that characterize the performance of the connector.

The working principle of the IEC 61455-2 connectors is to ensure that the source of power (e.g. the appliance) and the cable are properly connected to each other. The IEC 61455-2 connector provides a secure connection, which should be able to withstand harsh environmental conditions, as well as the applicable mechanical and electrical loads. The connectors provide a reliable connection and stable performance over time.

The IEC 61455-2 connector has several advantages over other types of connectors. It is easy to install, supports a wide range of cable sizes, is durable, and has a low profile. Additionally, the connector is able to withstand numerous mechanical and electrical loads, which contribute to its high reliability over time. The connector is also designed to ensure a seal that will prevent the ingress of foreign matter.

In conclusion, IEC 61455-2 is a specialized connector whose main purpose is to ensure safe and reliable operation of machines and devices by providing a secure and reliable connection while supporting a wide range of cable sizes. The IEC 61455-2 connector supports multiple parameters that characterize its performance and provides a durable connection with good environmental resistance.
