MMCX Straight Crimp Plug for RG178,RG196

MMCX Straight Crimp Plug for RG178,RG196

Information


This MMCX Straight plug connector has snap-on coupling mating and is designed to be crimped with coaxial cable like RG178 and RG196.

The biggest characteristic of MMCX plug is its “C-clip”

This MMCX Straight Crimp plug is machined of RoHS compliant copper, and has gold plating.

Cable Assembly

Cable Assembly Instructions Crimp type

Step1. All parts of MMCX connector are shown as the top line.

Step2. Strip the RG174 into center conductor, insulator, shielding three parts per recommended stripping dimension shown in connector spec.

Step3. Slide the ferrule onto the cable jacket.

Step4. Put the center conductor into the contact pin of MMCX plug and then solder through the hole.

Step5. Put the contact pin into main body until it stops and then spread out the shielding onto the knurled part and then

Step6. Slide the ferrule over the shielding, and proceed the first open-short test to make sure signal can transmit well.

Step7. Crimp the ferrule to let it become tighter.

Step8. Wear the heat shrink onto the ferrule and then shrink it.

Step9. Do the open-short test of every cable assembly before QC examination.
