These connectors

18、use crimp contacts. The receptacles and plugs contain either male contacts or female contacts. The connectors are polarized by a master key ; polarization shall be obtained before the male contacts enter the insulator of the female contacts and before the coupling ring is engaged. The visual control

19、 of coupling is obtained by color markings on the plugs coupling ring. 4.1 Materials and surface treatment When dissimilar metals are in close contact, adequate protection against corrosion shall be used for the electromotive force of the cell not to exceed 0,25 V. 4.1.1 Housings The material of the

20、 connector housing shall be steel protected against corrosion by a passivated cadmium plating. 3) Published by : Department Of Defense (DOD), the Pentagon, Washington, D.C. 20301, USA. 4) Published by : EUROCAE (Organisation Europeenne pour IEquipement Electronique de lAviation Civile) 11, rue Hamel

Non-resilient material used in the

22、 production of the insulators shall have electrical and mechanical characteristics compatible with the required use. 5 Design 5.1 Housings They shall be in one unit. The plug shall also be fitted with an O-ring to ensure that the housings are tightly sealed when mated. The coupling ring shall be des

23、igned so that the male and female contacts engage when it is screwed to the right and disengage when it is unscrewed to the left. The coupling ring shall be knurled. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and the plug. Appearance of co

24、lor (orange or red) in six lock displays located on the coupling ring shall show that the connectors are correctly coupled. The contacts are fitted in the housings by compressing them with the various insulators. These insulators are fixed inside the connector housings and held in place by tightenin

25、g a rear screw fitting that shall have at least three holes for passage of a lockwire. Threads shall comply with FED-STD-H28. 5.2 Insulators The insulator supporting the male and female contacts shall be in rigid material and have a cross section and radii such that no cracks, flaking or breaks can

26、occur in normal operation. The front face of the insulator shall be such that sealing is ensured when the connectors are coupled. The interface seal of the insulator of the male contacts shall be bonded on the rigid insulator. The grommet shall permit suitable sealing for all cable diameters indicat

27、ed in EN 6047-002. It shall be removable. The insulators shall be removable and mechanically polarized by a keyikeyway system and held tight in place by the connector backshell. An O-ring shall be fitted to ensure correct sealing between the rear insulators and the housings. AECMA PRENub047- 001 95
