Overview

The AINEX DC-023 Connector Cover Set is a practical accessory designed to protect unused ports on gaming PCs, workstations, and peripherals from dust and debris. Each single set includes 37 caps covering USB Type-C (with tab, 3 pcs), USB Type-A (with tab, 10 pcs), USB Type-A (no tab, 4 pcs), DisplayPort (4 pcs), HDMI Type A (3 pcs), DVI (1 pc), VGA mini D-Sub15 (1 pc), 3.5mm mini jack (8 pcs), RJ-45 LAN (2 pcs), and wireless LAN antenna (2 pcs). The caps are molded in black (except the antenna caps which are natural) and made from PE, PP, Nylon 66, or ABS depending on the connector type. The product is RoHS compliant. This package contains three complete sets, making it ideal for covering multiple PCs or devices at once. The caps are simple to install and remove, and the tabbed USB versions offer easy grip for frequent plugging/unplugging.

Connectivity & Compatibility

The DC-023 covers the most common ports found on modern desktop and laptop PCs. USB Type-C caps fit standard USB-C ports; USB Type-A caps (both with and without tabs) fit standard USB-A ports. DisplayPort and HDMI caps protect video outputs on graphics cards and monitors. DVI and VGA caps are for legacy video ports. Mini jack caps fit 3.5mm audio jacks (headphone, microphone, line-in). LAN caps cover RJ-45 Ethernet ports. Wireless LAN antenna caps fit the threaded antenna connectors commonly found on Wi-Fi cards and routers. The tabbed USB caps are easier to remove when you need to use the port, while the tabless versions sit flush and avoid interfering with adjacent ports. All caps are designed to stay securely in place but can be removed without tools.

Product Info

The AINEX DC-023 was released around 2024 and is widely available through Japan and other online retailers. The three-pack typically costs around ¥2,000, offering excellent value per cap. The product comes with no additional accessories; just the caps themselves. Warranty is the standard manufacturer defect coverage. In terms of market positioning, this is an entry-level to mid-range accessory. It doesn't offer any active functionality or flashy design, but it fulfills a basic need for port protection at a very low cost. It's a practical purchase for anyone who wants to keep their PC clean and tidy.

Best Use Cases

DIY PC builders: After assembling a new system, many ports remain unused. Placing caps on rear USB, audio, and video ports prevents dust buildup and keeps the interior looking fresh for years. Gamers with multiple peripherals: If you frequently swap cables (e.g., different headsets, controllers), having caps on unused ports ensures they stay clean and ready for use. The black color blends well with most gaming PC aesthetics. Office and creative professionals: A tidy desk improves workflow. Caps on unused ports reduce visual clutter and prevent accidental insertion of foreign objects. Users managing multiple PCs: With three sets in the package, you can protect a desktop, a laptop, and a monitor or docking station simultaneously. This product is less useful for users who constantly use every port on their system, or for those who don't mind a bit of dust. Also, caps may not fit recessed or oddly shaped ports, so check compatibility before buying.
