Barrel - Power Connectors

Barrel - Power Connectors are devices that safely facilitate the connection and provide electrical power between two devices. The PJ-102A is a barrel - power connector that is used in electrical and electronic applications. This article covers the application fields and working principles of the PJ-102A.

Application fields

The PJ-102A is a 2.1mm power connector that is designed to provide electrical power from one device to another. It can be used in a wide range of applications, from powering computer peripherals to connecting audio/visual equipment. Other applications include: automobiles, robotics, security systems, medical equipment, and leisure projects.

The PJ-102A is available in a variety of dimensions and types, with a vast range of connection configurations and styles. These include right angle, straight, PCB mount, screw thread, and panel mount. Additionally, this type of connector is available with different types of electrical insulation, such as rubber, nylon, thermoplastic, and polyurethane, allowing it to safely fit applications with different levels of mechanical and electrical stress.

Working Principle

The PJ-102A follows the same working principle as other barrel power connectors. It is a simple, yet reliable, electrical connection that uses a system of conductive pins or blades. Two mating halves are used to secure an electric connection between the two parts. The pins or blades usually come in pairs, with one side connected to a source of power and the other side connected to the device requiring power, such as a battery, adapter, or motor.

When the halves of the PJ-102A connector are mated together, a secure electric connection is made. The system is designed so that the pins or blades easily fit into the corresponding slots or holes on the opposing half, creating an interlocking, tight fit. This ensures that the connection will remain secure and safe, even when exposed to excessive vibrations.

The size and shape of the pins or blades determine what type of connection they are best suited to, as different designs guarantee different levels of power transfer. The PJ-102A is a two-pole, five-insulated system, meaning it is ideal for transferring medium amounts of power.

Conclusion

The PJ-102A barrel - power connector is an essential device for powering and connecting electronic applications. It is available in a variety of sizes, configurations, and insulation types, providing the user with a wide range of options for their application. Additionally, its simple yet effective system of pins and blades ensures a secure electrical connection between sources of power and devices.
