Heavy Duty Connectors - Housings, Hoods, Bases

When selecting a heavy duty connector, the various components that make up the that particular electrical interconnection are just as important as understanding the connector’s application field and working principle. The three main components of a heavy-duty connector are the housings, hoods and bases, which together include the electrical and environmental protection required for a safe and reliable connection.

Connector Housings

Connector housings are the largest component of a connector system. Apart from a mechanical structure to protect the contacts, housings come with different elements that enhance its reliability and safety conditions. This includes a proper connection system, such as a bayonet, threaded or snap-in locking mechanism to ensure a lasting connection and prevent accidental disconnection.

Connector housings also come with sealing elements, like aluminium core-gaskets, deformable plastic gaskets, viton-rubber gaskets, etc. Sealing elements offered by the housing mechanisms helps prevent water and dust ingress and other environmental pollutants. It is important to choose the right sealing system according to the application environment where the connection needs to operate.

Connector Hoods and Bases

Connector hoods are the covers that fit over the housing components and come with polarity devices to ensure the contacts are correctly wired on the back end. They also offer seal elements to protect against water and dust ingress and are available in different materials according to specific requirements. Those made from stainless steel offer easier cleaning advantages over other materials.

Connector bases are the components that are inserted into the rear housing piece. The base is usually fitted with sockets to which the wires can be attached. The electrical contacts used are usually made from metal and require proper insulation to ensure safe and secure connection.

Application Field and Working Principles

Heavy duty connectors are used for a variety of applications, from industrial machines and controllers, to automotive sector, transportation systems, and medical equipment. Generally, the connector type and number of contacts needed depends on the application, and each application has its own criteria for selecting the proper type of interconnect and connectors’ components.

The working principle of these connectors is to provide a secure and reliable electrical connection between two points. Heavy duty connectors help prevent accidental connections, and the housing, hoods, and bases provide the reliable mechanical connection and environmental protection needed to ensure the quality of electrical connection between the two devices.

When selecting a heavy duty connector, it is important to consider the type of application and environment where the connector will operate, as well as to select the right components that will match the application’s requirements. By selecting quality components and connectors, a secure and reliable connection is guaranteed.
