Connection principle of circular connectors

The main structural components of a circular connector include four main parts: shell, contact, insulator, and attachment. In the connector design, in order to meet the rated current requirements, is realized through the thermal design of the connector. When there is current passing through the connector, the contact pairs will heat up due to the conductor resistance and contact resistance of the connector. However, once the connector heats up beyond the rated limit, the insulation of the circular connector will be damaged, causing softening of the surface plating and malfunctioning of the connector. This is the importance of limiting the rated current of the connector, is to avoid the connector internal temperature exceeds the limit, resulting in damage to the connector. When selecting Tyco circular connectors, it is important to note that for multi-core connectors, the rated current must be derated. In short, in the connector connection operation should start from all aspects, to avoid the connector work when there is a possibility of failure problems, to ensure the normal operation of the equipment.
