[Product Overview] DC-028 Horizontal Right-Angle PCB-Mounted DC Power Jack

DC-028 is a classic horizontal right-angle 90° PCB-mounted DC power jack (female connector)5.5×2.1mm and and 5.5×2.5mm designed to standard adapter power plugs, fully aligned with PCB Through-Hole Mount industrial-grade connector design standards.

DC-028 is specifically designed for board-edge mounting, with pins in a 90-degree bent DIP through-hole configuration that can be directly inserted into PCB pads for wave soldering or manual soldering. The front features a precision square plastic mounting frame and enclosure latch, which, once installed, fits perfectly against the device chassis, effectively withstanding lateral stress and push-pull forces when plugging and unplugging power adapters, protecting PCB solder joints from cracking.

[Expert-Level B-Side Selling Points and B2B Procurement Decision Factors]

1. 90° right-angle horizontal DIP pins, specifically designed for PCB board-edge layouts

The standard 90-degree bent DIP structure is compatible with automated wave soldering and insertion assembly lines, offering strong solder joints and excellent pull-out resistance. It is the preferred specification for board-edge power interfaces in various enclosed electronic products.

2. Square housing slot design, excellent crush resistance and protection

The front section of the housing features a square countersunk frame with side slots, allowing direct snap-fit into the chassis opening, preventing the force from plugging/unplugging the male connector from being transmitted directly to the PCB solder pads, greatly enhancing the device's drop resistance and plug/unplug durability.

3. High-elasticity copper alloy contact springs, low contact resistance without overheating

The internal springs and center pin are crafted from high-conductivity beryllium copper/phosphor bronze, with nickel/silver plating on the surface, achieving a contact resistance as low as ≤0.03Ω, ensuring stable power supply without overheating during prolonged operation under high current loads.

4. UL94V-0 flame-retardant high-temperature engineering plastic

The base is injection-molded from high-grade flame-retardant engineering plastic, offering strong thermal shock resistance, with no collapse, deformation, or displacement during wave soldering (260°C), and excellent internal insulation performance.
