In industrial applications, a heavy duty connector is used where it is needed to assemble machinery and facilities in a time-saving and secure way. The connectors are designed for extremely rough environments, and their housings are made of a high-quality metal so that they can protect the internal structure from moisture, water, dirt, and mechanical stress.
Heavy duty connectors feature an exclusive modular design that makes the signal and power distribution simple and makes it possible to integrate several metrics such as data transmissions, pneumatics, power, signals, and more into a single connector.
Different manufacturers produce various types of heavy duty connectors suitable for particular applications. For example, heavy duty power connectors are used in facility engineering, construction machinery, utility vehicles, and other sectors while the flexible connectors are especially suitable for automotive industry and control technology.
Different Parts of a Heavy Duty Connector
Broadly speaking, heavy duty connectors have four main sections – a hood, a protective enclosure or housing, male insert, and female insert.
The outer plug cover of a connector is known as the hood.
Most of the manufacturers use high-quality die-cast aluminum for making the protective enclosure. Aluminum is compact and lightweight, but at the same time it is durable and offers protection against many environmental stresses such as impact, frost, and corrosion.
Connectors made of die-cast aluminum can be used in even the harshest environmental conditions.
It is the part that stays outside and is assembled into the hood.
It is the internal structure of a heavy-duty connector, and it does electrical functioning. Manufacturers use high-grade insulation materials to ensure that the connectors can securely transmit high voltage of current in a tight space.
Heavy duty connectors mainly feature two types of inserts – universal and flexible – that are compatible for all of their applications.
How to Select the Right Heavy Duty Connector
There are some metrics to be considered when choosing heavy duty connectors for an industrial application.
Connectors come in various sizes. So, it’s important to choose the right size and combination because each one is compatible for a particular installation in an industrial application.
Some manufacturers produce connectors with a specific size number such as ‘A’ or ‘B’ while some others use the distance of the screw fixing center as the standard of measurement.
A couple of locking systems are available. You have to choose one that fits your requirements. A single locking system can lock the hood and housing together by rotating a lever. Double locking systems have two levers for added security.
The gasket design is important because it guarantees the sealing of the connectors. A proper gasket design should protect the internal structure and allow proper dissipation of pollution outside so that water and dust can escape easily.
