There are several power connection types, and selection comes down to the kind of electrical current being carried and an application’s requirements. By looking at how electrical power connections are classified and the characteristics of each variation, you will be able to decide which connector is most appropriate.
Any device that allows the transfer of power between a power source and a component is considered a power connector in the broad sense of the term. Because of the numerous applications that benefit from the implementation of power connectors, they come in an array of forms. Some of the most common power connections include plugs used to connect appliances to wall outlets, specialized connectors found in computer cases, and battery cables utilized to link batteries to vehicles.
When discussing electrical components, a specific type of power connection is usually also in conversation. These power connections offer characteristics that make them perfect for certain applications, especially those of which are demanding in nature. Conductivity principles govern how a power connection operates. In simplistic terms, a power connection is made of a conductive substance and some form of adaptor that enables the interaction between a power supply and a load.
In general, some connectors feature a rating to ensure that any single connector is not linked to a power supply that is too strong for the devices it powers. For instance, an electrical plug cannot be connected to certain appliances using an extension cable because the power connector’s cord may experience an oversurge of current flow. This can lead to the cord heating up and causing a fire or other incident. More than that, power connectors must also be insulated to avoid other forms of injury.
In order for the user to avoid contact with the metal leads that actually create the connection, the power connector on a wall socket is encapsulated in an insulated substance. This way, the user would need to intentionally make contact with the metal prongs after inserting the connector into the socket. Despite this danger, it is not very common for users to stick their fingers in wall sockets. If there are children present, outlet covers can be used when a socket is not in use.
Various Types of Electrical Power Connectors
There are many types of electrical power connectors, some of which we will cover in this section.
Automotive Connectors allow for multiple connections to be established to different low-current electrical circuits used in cars. They are often made of materials that are resistant to petrochemicals present in varying car parts and made to withstand the severe weather that every automobile is subjected to.
DC Power Plugs are available in many different styles with the most common variations having a metal cylindrical shape that allows it to fit into a certain kind of pin. Typically, they are used alongside a transformer plug to reduce the voltage to a level suitable for the equipment in question.
Compact Power Connectors are manufactured in numerous types and are made to be used in equipment where power connections must be as discreet and seamless as possible. In most cases, they are equipped with many safety precautions to keep users away from the leads themselves.
DC Power Sockets are the receptacles for DC power plugs, and the single prong in the center of the cylindrically-shaped socket makes them easy to identify.
Industrial Interlocks are a type of safety tool that is used to prevent the unintentional activation of machinery, electrical circuits, or other forms of industrial equipment. They ensure that the worker operating any particular machine avoids being hurt or killed by live wires.
