AECO ABC-1471 Male 70-ohm Beryllium Copper BNC plug, Gold-plated

Designed for 75 ohm systems, the ABC-1471 BNC plug maintains consistent conductor and insulation diameter ratio for optimal transmission performance. With the conductors being connected via soldering or crimping and the contact material being high-purity beryllium copper, nickel-free plating.

Specifically engineered for 75 Ω use—ideal for video and SAT systems.

Main contact pin supports various secondary pins for increased compatibility. Secondary pins have cross-cut, shrink-fit design; support both solder and crimp methods.

Materials & Finish

• Contact Pin: Beryllium Copper (C17300 ≥97% Cu), 10 µ″ gold plating (no nickel)

• Shell and Body: Brass Zinc Alloy (C3604), satin-nickel + topcoat

• Spring & Washer: Steel, nickel-plated

• Screws: Stainless Steel (SUS304), natural finish

Mechanical Structure

• Main contact pin uses barb hooks into insulation during assembly

• Secondary pin secured via crimping method

• Body and insulation interlock via barb hooks; middle shell piece fixed by punch riveting

• Front shell riveted with spring & washer; independently rotatable

• Middle and rear shells locked by screwing; secured to cable with screw

Assembly Instructions

1. Cable Preparation

1.1 For Cable OD < 7.5 mm

1. Fit rear shell part (301); remove sleeve (311/312) if needed.

2. Peel shield 6.0 mm back.

3. Remove braid + dielectric by X − 2 mm (X = cable OD)

4. Spread braid radially (~12 mm diameter); remove foil/dielectric in area.

5. Ensure core protrudes 3.0 mm beyond braid

1.2 For Cable OD 7.5–10.5 mm

1. Peel shield 20 mm back.

2. Remove braid + dielectric by X − 2 mm.

3. Fit rear shell (301); remove sleeve (311/312) if needed.

4. Spread braid (~12 mm diameter); remove foil/dielectric.

5. Ensure core protrudes 3.0 mm beyond braid

2. Contact Pin Installation

1. Select secondary contact pin (2 of each):

   • 201: ID 1.3 mm

   • 202: ID 0.9 mm

   • 203: ID 0.5 mm

2. Chamfer cable core tip via chipping or milling

3. Choose method:

   • Crimp: Clamp pin and insert onto conductor.

   • Solder: Clamp and solder pin to conductor.

3. Final Assembly

1. Insert contact pin and cable into main pin inside shell (100).

2. Ensure braid is radial; lock rear shell (301) into middle shell

3. Secure cable to rear shell with screw (321/322).
