The three coupling nut styles illustrated represent one of the types used to complete an Ordnance Assembly. In all cases; they must be assembled to its respective assembly, prior to soldering operations.
The Crown Flat Flange Gasket of synthetic rubber material is provided to further complete the moisture-proofing and pressure sealing features of Crown connectors. It is for use with flange mounting receptacles.
This assembly provides for a moisture-proof, dust proof sealing for the receptacle when unmated. Chain and eyelet provide permanent attachment under the mounting bolt of the receptacle assembly.
This receptacle, together with its mating plug, is designed to withstand a 17.7 KVAC rms potential at 60 CPS for one minute, using JAN RG-8/U cable (or equivalent). Protection from vibration is ensured through the dampening action of the Crown resilient insert and the strength of special alloy aluminum shells.
The CR1000 Adapter is designed as a functional equivalent to the SM-C-339543. This new design has incorporated the six component parts and eight groups of the Signal Corp. Adapter into only three component parts and three groups. Some advantages offered by the CR1000 are: reductions in cost, overall length, weight and a reduction in the number of parts that are subject to corrosion.
