Page 58 of 114 NASA-STD-8739.4 with Change 6 Figure 11-5. Group-Grounding of Individual Shield Terminations 11.7 Large Compression Ring Grounding Individual shields and overall shields may be grounded using large compression rings. Shields should be dressed across the inner collector ring either forward towards the connector (Figure 11-6B) or backwards away from the connector (Figure 11-6C). Grounding wires shall exit the front or rear of the compression ring as required by design, and shall be formed in accordance with Figure 11-6A (Requirement). Grounding exiting the side of the compression ring away from the rear of the connector shall be dressed beneath the compression ring when terminating to a connector pin (Figure 11-6D). The outer compression ring shall be crimped securely over the shields and inner collector ring (Figure 11-6E) (Requirement). The grounding wire detachment force from the crimped sleeve shall meet the requirements of paragraph 13.7 (Requirement). Figure 11-6. Large Compression Ring Grounding (Typical Applications)
11.8 Floating Shield Terminations Figure 11-6. (continued) Page 59 of 114 NASA-STD-8739.4 with Change 6 The outer jacket shall be trimmed to expose the shielding braid (Requirement). The braid shall be folded back over the outer jacket as illustrated in Figure 11-7 (Requirement). Combing the braid is optional. Heat-shrinkable sleeving shall be installed over the trim point (Requirement).
