Description
2.1mm x 5.5mm DC Power Jack Female Connector (Screw Terminal Block) The Solderless DC Power Jack Female Connector is a highly practical adapter that allows you to easily connect bare wires to a standard female barrel jack socket. Designed to save installation time, it features a heavy-duty 2-pin screw terminal block on one end and a standard 5.5mm x 2.1mm female barrel socket on the other. This connector eliminates the need for soldering or wire splicing, making it an indispensable component for quick field configurations, security setups, and low-voltage electrical projects. Key Features Connectors: 1 x DC Barrel Female Socket (5.5mm outer diameter, 2.1mm inner pin diameter) to a 2-Pin Screw Terminal Block. Solderless Convenience: Features integrated screw-clamp terminals that secure stripped wire leads firmly with a simple turn of a screwdriver. Polarity Matching: Clearly stamped with [ + ] (Positive) and [ – ] (Negative) markings to ensure proper electrical phasing and protect equipment from reverse-polarity damage. Electrical Capacity: Rated for standard low-voltage applications, typically up to 12V–24V DC at 5A. Build Quality: Molded PVC plastic body with standard nickel-plated contact sleeves to prevent oxidation and maintain a steady power delivery. Compatibility Guide This adapter is a universal low-voltage interface part widely used across security surveillance systems, DIY prototyping, and decorative LED lighting setups. 1. Compatible Power Sources (Input via Male Plug) AC/DC Wall Adapters: Accepts standard “wall wart” power supply bricks with a 5.5mm x 2.1mm male plug from generic or name-brand manufacturers. CCTV Power Distribution Boxes: Connects standard multi-channel centralized power supply feeds directly to line distributions. 12V/24V Battery Packs: Connects straight to the output lines of custom lithium-ion or lead-acid battery packs using raw wiring. 2. Compatible Equipment & Cabling (Output via Terminals) CCTV Surveillance Cables: Connects bare power strands of Siamese coaxial cables (RG59 + DC Power) or Cat5e/Cat6 UTP networking cables using wire pairs to run power to security cameras. LED Strip Lighting Spools: Feeds incoming DC power lines directly into single-color or RGB LED controller boards and strips (SMD 3528, 5050, 5630). Development Boards: Connects custom power arrays to the raw pin lines of Arduino, ESP32, ESP8266, and Raspberry Pi hobbyist projects. Matching Connectors: Pairs seamlessly with its direct counterpart, the 2.1mm x 5.5mm DC Power Jack Male Screw Terminal Adapter, to create a quick-disconnect inline cable joiner.
