Solderless Gold-Plated RCA Plugs – Metal AV Audio/Video Connectors for Amplifier, Speaker & DIY

Solderless gold-plated RCA (phono) plugs with screw clamp termination — no soldering iron required. The screw clamp mechanism grips the center conductor and shield/braid separately, providing a secure connection without heat. Metal body construction provides better shielding and mechanical durability than plastic-body RCA plugs. Suitable for DIY audio cable assembly, amplifier connections, speaker wiring, and AV equipment interconnects where soldering equipment is not available or practical.

Solderless vs Solder-Type RCA Plugs

• Solder-type: Wire soldered to the center pin and outer shell. Lowest contact resistance. Permanent — requires desoldering to change. Best for permanent installations and highest-quality audio connections.
• Solderless screw clamp (this product): Wire clamped by screws. No soldering required — assemble with a screwdriver only. Slightly higher contact resistance than solder type. Allows wire removal and reinsertion. Best for: field assembly without soldering equipment, temporary connections, and applications where the cable may need to be changed.
• Crimp-type: Wire crimped to the contact. Requires a coaxial crimp tool. Provides consistent, low-resistance connections. Best for production environments with crimp tooling.

Frequently Asked Questions

How do I assemble a solderless RCA plug?

1. Slide the outer shell and strain relief over the cable. 2. Strip the cable jacket 20–25mm. 3. Fold the braid/shield back over the jacket. 4. Strip the center conductor insulation 8–10mm. 5. Insert the center conductor into the center pin clamp screw and tighten. 6. Fold the braid into the outer shell clamp and tighten. 7. Slide the outer shell forward and tighten onto the body. 8. Test with a multimeter: verify continuity from center conductor to center pin, and no short between center pin and outer shell.

What cable is compatible with these plugs?

Standard coaxial audio cable with OD 4–7mm: RG174 (thin, flexible), RG59 (standard), or dedicated audio coaxial cable (Mogami, Canare, Belden). Verify the cable OD fits within the plug’s cable entry range before cutting. The cable must have a center conductor and a braid/foil shield — two-conductor non-coaxial cable is not suitable for RCA plugs.

Are solderless RCA plugs suitable for high-end audio?

For critical listening applications, solder-type RCA plugs provide lower and more consistent contact resistance than screw clamp types. Solderless plugs are suitable for home theater, AV equipment, and general audio use where the slight increase in contact resistance is not audible. For audiophile applications where every connection is optimized, use solder-type plugs with silver solder and high-quality cable.

Typical Applications

• Home theater: Subwoofer cables, source-to-amplifier interconnects
• AV installation: Composite video and analog audio cable assembly
• DJ equipment: Turntable and mixer interconnect cables
• DIY audio: Custom-length RCA cables without soldering equipment
• CCTV: Composite video cable assembly for analog camera systems
