14、OD WILL DEPEND ON THE ACCEPTED TECHNIQUES OF THE USER. THE TERMINATION AND GROUND RING REQUIRES NO SPECIAL ASSEMBLY TOOLS AND CAN BE ASSEMBLED BY HAND. HOWEVER, THE USER MAY FIND IT PREFERABLE TO USE SOFT JAW PLIERS FOR FINAL TIGHTENING OF THE TERMINATION AND GROUND RINGS. IN ALL CASES, A SELF-PIGTA

15、ILING TECHNIQUE FOR THE INDIVIDUAL SHIELDS IS USED, WITH THE POINT AT WHICH THE CONDUCTORS ARE EXTRACTED THROUGH THE SHIELDS TO BE DETERMINED BY THE PARTICULAR CONNECTOR INVOLVED. FOR SOLDER CONTACT CONNECTORS, THE LENGTH OF THE EXTRACTED CONDUCTOR WILL BE SHORTER THAN FOR THE CRIMP CONTACT CONNECTO

16、RS. IT IS SUGGESTED THAT ALL SHIELD PIGTAILS BE FLATTENED BEFORE INSTALLING THE TERMINATION AND GROUND RING. TERMINATION AND GROUND RING: a. PLACE TERMINATION AND GROUND RING ON WIRE BUNDLE OR CABLE WITH CASTELLATED (SLOTTED) FACE OF BODY TOWARD TERMINATION END OF CABLE (SEE FIGURE 2, STEP 1). b. IF

17、 SHIELDED CONDUCTORS HAVE AN OUTER JACKET, STRIP JACKET TO DESIRED LENGTH. EXTRACT CONDUCTORS THROUGH SHIELDS AT LOCATION DESIRED FOR INSTALLATION OF THE TERMINATION AND GROUND RING.
