Do-It-Yourself Insulated BNC (M) Connector, 50 Ohm
Assembly Instructions
Step 1: Gather the following items.
1. 5 BNC connector parts (front insulator, contact pin, main metal part with knurled area, crimping
ferrule, main insulator)
2. Crimping tool with crimp die cavity hex size of 0.213” (5.4mm)
3. Coaxial cable
4. 80 watt maximum soldering iron
5. A piece of tin wire
Step 2: Slip the main insulator on the coaxial wire and slip the crimping ferrule on the coaxial wire.
Step 3: Strip the coaxial wire as shown below.
Step 4: Solder the pin on the inner conductor of the coaxial wire. Insert the pin into the main metal part by
holding the coaxial wire and push it unti it locks into place.
Step 5: Lay the braiding on the knurled area of the main metal part. Slip the crimping ferrule on the
braiding. Crimp the crimping ferrule with crimping tool and die cavity hex size of 0.213” (5.4mm).
Step 6: Assemble the front insulator with the main insulator by taking care of the indexing plastic pin. Push
until it locks into place.
The BNC male connector is ready to use.
