Female DC Power (2.1mm) Plastic Connector for Box (DC1)

Description

Female DC Power (2.1mm) Plastic Panel Mount Connector (Model: DC1)

Product Overview

The DC1 Female DC Power Plastic Connector is a lightweight, high-isolation barrel jack receptacle engineered specifically for mounting onto plastic project boxes, custom enclosures, and electronic equipment chassis. Featuring the industry-standard 2.1mm center pin within a 5.5mm outer sleeve socket, this component allows your hardware devices to accept direct low-voltage power from ubiquitous commercial AC/DC wall adapters and benchtop power supplies.

Unlike heavy metal-threaded alternatives, the DC1 is molded from a high-impact, electrically insulative engineering polymer body that eliminates the risk of accidental chassis grounding or short-circuits against panel walls. Designed for clean, front- or rear-loading box installation, it secures tightly via an included hex locking nut, ensuring a stable, wobble-free interface that withstands repeated plug insertion and extraction cycles.

Key Features

• Universal 2.1mm x 5.5mm Footprint: Precision-machined to form a tight, snap-fit physical connection with standard 2.1mm male barrel plugs, entirely preventing intermittent power drops from cable tugs.

• High-Isolation Plastic Housing: Molded from premium, non-conductive engineering plastic (Model: DC1) that provides absolute electrical isolation, making it ideal for non-grounded plastic enclosures.

• Integrated Internal Shunt Switch: Features a clever three-pin contact layout that automatically disconnects an internal battery circuit when a male DC wall plug is inserted, switching the system seamlessly to external power.

• Secure Box-Threaded Mounting: Equipped with a dedicated backing washer and heavy plastic/metal hex nut that locks the socket firmly into pre-drilled box holes, preventing rotation during use.

• Excellent Solder Heat Resistance: Outfitted with heavy-duty internal terminal tabs that maintain structural pin alignment even under high manual soldering temperatures.

Technical Specifications

Applications

The ideal, low-isolation power entry interface for small plastic enclosures, custom instruments, and prototyping boxes:

• Plastic Project Box Power Inputs: Serving as the primary power entry node on 3D-printed cases, ABS junction boxes, and hand-held device housings to pipe in 5V, 12V, or 24V DC paths cleanly.

• Automatic Battery-to-Mains Switching: Utilizing the internal shunt pin to build automatic power-selection circuits that bypass internal AA or Li-ion battery packs the moment an external wall adapter is plugged in.

• Smart Home & IoT Sensor Boxes: Providing an easily disconnectable, low-profile power input node for localized ESP32/Arduino smart nodes, relay modules, and environmental telemetry cases.

• DIY Bench Equipment Prototyping: Ideal for building or modifying small desktop hardware tools, logic trainer kits, and dedicated battery-charging bays housed in plastic enclosures.
