USB AF Black Plastic Reverse Female Connector (Reverse/Inverted Mount Horizontal 90-Degree DIP/4Pin USB 2.0/Black High-Temperature Resistant Plastic Core/Dual Side Positioning Pins Reinforced/Specifically for Industrial Control Motherboards and Automotive Electronics)
Black glue reverse inverted structure | Adapts to special height and structural designs | 4Pin standard USB 2.0 transmission | High-temperature resistant black glue material | Multi-point positioning feet anti-prying | Free samples and CAD drawings
This USB AF black plastic reverse female connector (USB Type-A Female Reverse/Inverted Mount Receptacle) features a precision design combining a "reverse/inverted structure + 4Pin precision conductive terminals + black high-temperature resistant engineering plastic (black plastic) + sturdy metal positioning pins." It is specifically tailored for hardware terminals where the motherboard and enclosure are constrained, requiring reversed plug-in orientation or adjustment of terminal contact surface height differences. The reverse structure effectively resolves the issue of plug insertion interference for standard forward female connectors with U-disk/cables at specific PCB layer heights. Internally, it uses 4Pin high-conductivity copper alloy terminals, fully compatible with USB 2.0 480Mbps high-speed data transmission and stable 1.5A~2.1A power supply. The outer shell is equipped with thickened positioning and fixing pins on both sides, which firmly secure it to the PCB after wave soldering/reflow soldering, offering outstanding pull-out resistance and anti-peeling performance. Widely used in industrial control motherboards, automotive multimedia head units, network set-top boxes, smart gateways, and various electronic devices with special structural openings. 2D/3D drawings and free sample requests are available.

【Product Overview】USB AF Black Plastic Reverse Female Connector (Reverse/Inverted Structure / Resolves Spatial Misalignment / 4Pin USB 2.0 Transmission / Black High-Temperature Resistant Plastic Core / Sturdy Positioning and Reinforcing Pins)
USB AF Black Plastic Reverse Female Connector (USB Type-A Female Reverse / Inverted Mount Receptacle) is a product specifically designed for Industrial control boards, automotive multimedia, set-top boxes, routers, and special enclosure structures A high-reliability reverse/inverted connector built for these applications.
In many hardware developments, due to enclosure opening constraints or motherboard and stacked board height issues, using standard forward female connectors may result in the plug being unable to insert or poor contact. This reverse (inverted) product addresses this through Reverse/inverted structure + black high-temperature resistant plastic + dual side reinforced solder pins , with the following core advantages:
- Reverse/inverted (reverse port) structure design (overcoming layer height and clearance constraints): Unlike standard forward female connectors, the internal tongue and terminals are arranged in reverse, effectively avoiding other low-profile components above the PCB and precisely aligning with asymmetric openings on the chassis side.
- Black high-temperature engineering plastic (black plastic, UL94-V0 rated): Made of high-insulation, high-temperature-resistant LCP/PBT engineering plastic, compatible with reflow soldering and wave soldering high-temperature baking, with no deformation or displacement at high temperatures.
- High-strength metal shielding shell + positioning reinforcement feet (strong peel resistance): The shell is wrapped in precision-stamped brass/stainless steel, with sturdy positioning reinforcement feet on both sides that lock firmly to the PCB after soldering, resisting high insertion/withdrawal forces and lateral prying.
- 4Pin standard USB 2.0 transmission and stable power supply: High-conductivity copper alloy terminals with gold-plated contact areas ensure ultra-low contact resistance, fully supporting USB 2.0 480Mbps high-speed data communication and stable power delivery of 1.5A~2.1A.
[Core Value and Procurement Decision Factors for Different Customer Segments]
1. For PCB Layout and mechanical engineers: avoid hole-opening interference and simplify structural modification costs
No need to rework the entire device housing mold; simply replace with a reverse-mount connector to perfectly match the panel opening, significantly reducing R&D trial-and-error costs.
2. For PE and process engineers: tight pin tolerances, full solder fillet after reflow
Pins and side positioning feet have good coplanarity, compatible with SMT/DIP hybrid soldering processes, with strong solder pull strength and extremely low rates of cold joints and misalignment.
3. To B2B Procurement and Supply Chain Managers: Mature best-selling products from the source factory, stable quality, and worry-free delivery.
Manufactured on Dongguan Sinyin Electronic's mature automated production line, with 100% implementation of continuity and contact resistance testing, large batch stock availability ensures rapid sampling and efficient material delivery.
