DC power connectors, also known as barrel connectors, are electrical connectors specifically designed to supply direct current (DC) power from the main connection to a device. Typically, they serve to power small and medium equipment with added cable assemblies. These connectors are comprised of three components, i.e., jack, plug, and receptacle, to operate. Read on to explore these exquisite connectors' different types, uses, and selection factors.
Popular Types of DC Power Connectors
The DC power connector is classified into several types; however, the standard connectors include barrel connectors, DIN connectors, and USB connectors.
- Barrel Connectors: The barrel connector is the most standard and cost-effective type, which features an insulated cylindrical tip. The ring (sleeves) within the end accepts a pin from the socket counterpart. This design aims to ensure a smooth disconnect and reconnect action and to make a connection safe and secure. Rather than that, it has many types with varied dimensions that cannot be exchanged.
- DIN Connectors: DIN power connectors encase four socket contacts, or pins, in a circular housing. They are ideal for moderate power applications where barrel connectors cannot carry a specific amount of power.
- USB Connectors: Initially, USB connectors were designed to provide digital signals and DC power. However, the compatibility features such as USB power voltage levels of these connectors make them ideal for power-only applications. They also come in various variants with numerous uses in different environments.
Choosing the Right DC Power Connectors
Special care should be taken before selecting these connectors. It is crucial to consider the insertion depth, the diameter of the inner pin, and the outer sleeve to mate them properly between jacks and plugs.
Why Use a DC Power Connector?
These power connectors are a cost-effective source, and with integral conductors, they help prevent an accidental short. Furthermore, they also avoid component damaging risks of plugging them inappropriately or into incorrect port pins.
What are the Typical Uses of DC Power Connectors?
The DC power plugs are ideal for smaller power appliances. They are mainly used in:
- Electronic Devices
- Portable Computers
- Automotive Accessories
- Battery Packs
- Sound Systems
