AECO ABC-1451 Male 50-ohm Beryllium Copper BNC plug, Gold-plated

The ABC-1451 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.

Ensure that the connectors and cables have matching specifications and impedance. Examples of standard systems: Japan: 4C, 5C & USA: RG-59, RG-6U.

Main contact pin supports various secondary pins for increased compatibility. Secondary pins feature a cross-cut and shrink-fit design.

Materials & Finish

• Contact Pin: Beryllium Copper (C17300), minimum 97% copper content, 10µ" gold plating, no nickel base.

• Body & Shell: Brass Zinc Alloy (C3604), gold or satin nickel plating with topcoat.

• Spring & Washer: Steel, nickel plated.

• Screws: Stainless Steel (SUS304), natural finish.

Mechanical Structure

• Main contact pin uses barb hooks to anchor into insulation.

• Secondary contact pin is secured using the crimp method.

• Shell body and insulation interlock using barb hooks; middle piece fixed with punch riveting.

• Front shell is riveted to the body and can rotate independently via a spring and washer.

• Rear and middle parts of the shell are screwed together and secured to the cable using a screw.

Assembly Instructions

1. Cable Preparation

1.1 For Cable OD < 7.5mm

1. Place the rear shell part (301) on the cable. Remove the sleeve (311/312) if necessary.

2. Peel back the shield by 6.0mm.

3. Remove the braid and dielectric by X - 2 mm, where X = cable OD including braid.

4. Spread the braid radially with the core pointing vertically. Spread diameter ≈ 12.0mm.

5. Remove any aluminium foil and dielectric in the spread area.

6. Ensure the core protrudes 3.0mm beyond the spread braid.

1.2 For Cable OD 7.5–10.5mm

1. Peel back the shield by 20.0mm.

2. Remove braid and dielectric by X - 2 mm.

3. Place the rear shell part (301) on the cable. Remove the sleeve (311/312) if necessary.

4. Spread the braid radially with the core pointing vertically. Spread diameter ≈ 12.0mm.

5. Remove any aluminium foil and dielectric in the spread area.

6. Ensure the core protrudes 3.0mm beyond the spread braid.

2. Contact Pin Installation

1. Select the appropriate secondary contact pin:

   • 201: Inner diameter = 1.3mm after shrink

   • 202: Inner diameter = 0.9mm after shrink

   • 203: Inner diameter = 0.5mm after shrink

2. Chamfer the cable core surface by chipping or milling.

3. Connect the secondary contact pin using one of the following methods:

   • Crimping: Clamp the pin and insert onto the centre conductor.

   • Soldering: Clamp the pin and solder it to the core.

3. Final Assembly

1. Insert the secondary contact pin and cable into the main contact pin in the shell’s middle section (100).

2. Ensure the braid is fully spread and radial.

3. Lock the rear part of the shell (301) into the middle shell section.

4. Secure the cable to the shell’s back using screw (321/322).
