If required by the procuring .activity,connectors shall be potted as specified on the applicable assemblydrawing (see 6.2).3.3.3 Shield termination. When ferrule shieldingterminations are being made, extreme care shall be exercis
37、ed inselecting the proper size ferrule rings and crimping tools toassure a reliable joint. Because of the danger of damaging theconductor insulation, solder shall not be used inmaking shieldingterminations with ferrules. All shields terminating with ferrulesShall have the ferrule assembly covered wi
38、th a snug, flexibleinsulating sleeve except where preinsulated ferrules are used. Thesleeve shall fit snugly over the ferrule assembly so that it doesnot slip during handling. The sleeve shall extend approximately0.250 inch beyond each ferrule end. A spot tie may be used betweeneach ferrule end and
39、the end of the insulating sleeve. Lacingcord, when required, shall be used for the spot tie. Clear heat-shrinkable sleeving may be used in lieu of the above, upon approvalof procuring activity. When a cable or harness assembly containsindividually shielded conductors, the shields may be terminatedwi
40、th the use of ferrules. If the assembly contains less than fiveindividuals shielded conductors, each shield may be terminated witheither a one- or two-piece ferrule assembly. The ferruleassemblies shall be staggered in the cable or harness as shown infigure 1 except where radio frequency interferenc
41、e attenuationrequirements demand that all ground leads to be the shortestpossible length. If the harness, cable, or wire bundles containsfive or more individually shielded conductors, each conductor shallbe prepared as described in 3.3.3.3.6 or 3.3.3.3.7.3.3.3.1 Jumpers. Jumpers and ground wires sha
42、ll befabricated from insuiatedr flexible, stranded wire (insulation oftype used in the assembly), or as specified on the detail drawing.In genqral, jumpers shall not cause strain on the terminationpoints.10Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-

The installation ofstandard one-piece ferrules (see 3.8 and 6.4.9) to terminate orground a braided shield shall be as follows:a Strip the insulation jacket, the braided shield, “and theconducorinsulation to the approximat
45、e length as shown in figure2.b. Flare the braid slightly by rotating the insulatedconductor as shown in figure 3.c. Select the proper ferrule by measuring the diameter of.-theconductor insulation and selecting theferrule in accordance“ithrespective dimensions shown, on applicable drawings.d. Select
46、the crimping dies recommended for the applicationin accordance with applicable drawings. Determine that thecrimping tool has been checked for proper adjustment. Gagesconforming to drawing requirements shall be used.Place ferrule in position, ferrule inner support ringunderehe cable shielding and the
47、 outer ring (as shown in figure 3)over the cable shielding as shown in figure 4.f. Place the ground wire between the braid and outer ring ofthe ferrule as shown in figure 5.9- Insert preassembled ferrule flush against the stop plateof the crimping tool (inspection holes of ferrule in visible andvert
48、ical position) as shown in figure 6 and close the crimping tooluntil dies are completely closed (dies closed to minimum opening orthe crimping tool ratchet releases) .h.
