JIYAYI 9+2 Mixed-Signal Power Connector for VTOL Fixed-Wing Aircraft - High Current Quick Release Plug

The JIYAYI 9+2 Mixed-Signal Power Connector provides enterprise drone builders with a professional, space-saving hub designed to handle high-stress flight connections and rapid field assembly routines.

Integrated Mixed-Contact Layout Architecture :

Setting up large-scale VTOL platforms or multi-servo fixed-wing aircraft usually requires routing messy independent bundles of high-amp ESC leads and delicate signal wires through narrow wing roots. JIYAYI eliminates this structural clutter by housing a hybrid terminal array inside a single plug. The dual power terminals isolate high-current battery loads, while the 9 adjacent gold-plated pins route multi-channel servo commands, navigation lights, and sensor telemetry lines cleanly.

Rugged High-Current Capability & Low Resistance :

Don't let its compact footprint fool you. The two primary power terminals feature solid, gold-plated brass bullet contacts engineered to sustain a heavy 30A continuous current (up to 60A instantaneous burst drops) at DC 500V. Boasting an ultra-low contact resistance of just 0.3mΩ, this connection block prevents restrictive thermal build-up and voltage drops during demanding vertical takeoff transitions.

Vibration Resistant Aviation-Grade Housing :

High-frequency multirotor vibrations and harsh aerodynamic wing-flex can loosen low-grade consumer plugs during flight. This aviation-focused quick plug is molded from high-impact flame-retardant PA plastic (UL94 V-0 Rated) and designed to maintain a high-friction mechanical lock. It reliably handles up to 1000 plug cycles, resisting structural wear from recurring field teardowns and rough grass landings.

Frequently Asked Questions :

Q1: What are the primary advantages of utilizing this mixed plug on a VTOL drone?

Ans: It allows for a single-point connection at the wing root. When assembling your VTOL or fixed-wing aircraft at the field, you simply slide the wing into place and insert one quick plug to instantly power your boom motors while simultaneously linking your aileron servos, flaps, and navigation lights. This saves significant setup time and removes the risk of miswiring individual leads.

Q2: What thickness of silicone wire should I solder to the rear terminal cups?

Ans: The two high-power solder cups are optimized to accept heavy-duty 12AWG or 14AWG high-flex silicone wire, making them ideal for high-amp ESC connections. The 9 smaller signal terminals are custom-sized to comfortably take standard 20AWG to 26AWG multi-strand servo leads or telemetry lines.

Q3: The connection feels incredibly tight when pulling it apart. Is this normal?

Ans: Yes, this is a conscious structural design feature for aviation hardware. The high separation force ensures that the connector blocks maintain a reliable connection through severe airframe vibrations, rapid wind shear transitions, and aggressive aerodynamic loading. When mounting, ensure your wing-root and fuselage backplates are structurally reinforced to handle the pull force during field teardowns.

Q4: Can I pass raw high-voltage battery power through the two main pins?

Ans: Absolutely. Rated for up to DC 500V and 30A continuous draw, these power terminals can comfortably route lines directly from standard 6S, 12S, or even higher voltage LiPo/Solid-State battery packs directly to your wing-mounted transition motors or primary ESC distribution modules.
