DC Power Jack Female Connector with 2-Pin Screw Terminal (PBT)

The DC Power Jack Female Connector with 2-Pin Screw Terminal (PBT) is a high-quality DC barrel socket adapter designed to provide fast, secure, and solder-free power connections for a wide range of low-voltage electronic devices. Featuring a standard 5.5mm × 2.1mm female DC jack and a convenient 2-pin screw terminal, this connector allows wires to be connected quickly using a simple screwdriver, eliminating the need for soldering and making installation clean, efficient, and reusable.

Constructed with a durable PBT (Polybutylene Terephthalate) housing, the connector offers excellent mechanical strength, high electrical insulation, and outstanding resistance to heat, wear, and environmental conditions. The high-quality metal contacts ensure excellent electrical conductivity, low contact resistance, and stable power transmission, while the screw terminal securely holds the wires in place to prevent accidental disconnection caused by vibration or movement.

The connector is compatible with standard 5.5mm × 2.1mm DC male barrel plugs, making it suitable for powering a wide variety of electronic equipment and low-voltage DC systems. Its compact and lightweight design enables easy installation in confined spaces, making it ideal for both temporary prototypes and permanent installations.

The DC Power Jack Female Connector with 2-Pin Screw Terminal (PBT) is widely used in CCTV camera systems, LED strip lighting, Arduino, ESP32, ESP8266, Raspberry Pi, STM32, DC power supplies, WiFi routers, alarm systems, battery packs, robotics, IoT devices, embedded systems, home automation, industrial electronics, educational projects, and DIY electronics. It is also commonly used for repairing damaged power connectors, extending DC power cables, and creating custom power distribution systems.

Whether you are building a new electronic project, installing surveillance equipment, repairing power connections, or designing custom DC wiring solutions, this connector offers a reliable, safe, and professional method for connecting low-voltage DC power without soldering.

Working Principle

The DC Power Jack Female Connector with 2-Pin Screw Terminal functions by connecting a standard 5.5mm × 2.1mm DC male barrel plug to two securely clamped wire terminals.

The connector consists of a female DC socket connected internally to a positive (+) and negative (−) screw terminal. After stripping the wire ends, they are inserted into the terminal openings and tightened using a screwdriver. Once secured, plugging a compatible DC male connector into the socket provides a stable electrical connection, allowing power to flow safely from the power source to the connected device.

The screw terminal design eliminates soldering, simplifies maintenance, and allows the connector to be reused multiple times without damaging the wiring.
