Plug and receptacle housings conform to EN 3645-001 standard. The connectors use rear removable optical contacts with a ferrule diameter of 1,25
24、 mm. The receptacles connector with male arrangement as specified EN 4645-003 and EN 4645-004. The plug connector with female arrangement as specified EN 4645-005. The female arrangement is equipped of a removable alignment sleeve holder as specified EN 4645-005. The sleeve holder is delivered with
25、the female arrangement. It is considered as a part of the female arrangement (specific design per manufacturer). 2) Published by: Department of Defense (DoD), the Pentagon, Washington, DC 20301, USA. prEN 4645-001:2008 5 The sleeve holder can be supplied separately only for repair purpose. The conne
26、ctors are polarized by means of keyways and keys; polarization is obtained before the male contacts enter the insert of the female contacts and before the coupling ring is engaged. The position of the keying arrangement is given in EN 3645-001. The visual check of coupling is obtained by masking of
27、a red coloured band on the receptacle. 4.1 Receptacle The receptacle may be attached by: square flange; jam nut. The receptacle contains five keyways in which the keys of the plug engage. The main keyway is fixed and is wider than the others. Polarization is ensured by the different positions which
28、the secondary keyways may take. The position of the insert is fixed relative to the main keyway. 4.2 Plug The plug contains five keys which engage in the keyways of the receptacle. The main key is wider than the others. Polarization is ensured by the different positions which the secondary keys may
29、take. The position of the insert is fixed relative to the main key. The coupling ring permanently fitted on the plug enables the connectors to be coupled and uncoupled. The mating torque shall be lower than the unmating torque. The internal thread of the coupling ring may be treated with a suitable
30、lubricant compatible with the performance required in this standard. 4.3 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 (see EN 3197). 4.3.1 Housings The mat
31、erial of the connector housings and fittings shall be of suitable material protected against corrosion by passivation, nickel or cadmium plating (see EN 3197) as specified in the product standard. 4.3.2 Optical contacts and alignment sleeves The material of the optical contacts and alignment sleeves
32、 shall be of suitable materials as specified in the product standard. The optical contacts in both plug and receptacle are sprung-loaded. The spring force is defined in the product standard. prEN 4645-001:20086 4.3.3 Metallic or non-metallic materials The materials used for insert, seals and grommet
33、s shall have hardness and mechanical characteristics consistent with the required use. The material used for guiding pins shall have hardness and mechanical characteristics consistent with the required use. 5 Design 5.1 Housings The connector housings shall be in one unit. They contain teeth at the
34、rear over the entire periphery and shall accommodate the cable outlets and other fittings. The receptacle shall be fitted with a seal for sealing the coupled housings. The jam nut receptacle housing shall contain an O-ring seal (panel seal). The lock nut shall be provided with wire locking holes. Th
35、reads shall conform to standards ISO/R 68:1973, ISO/R 261:1973, ISO/R 262:1973 and ISO/R 965:1973, except for the triple start threads, which shall conform to standard MIL-STD-1373. The coupling ring shall be designed so that the optical contacts engage when it is screwed clockwise and disengage whe
36、n it is unscrewed counter clockwise. The coupling ring shall be designed to provide a hand grip profile. Full locking of the connectors shall occur at approximately 360. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and plug shells. Masking o
37、f a red colour band on the receptacle shall show that the connectors are correctly mated. The front face of the plug shell shall seal when fully mated with the receptacle connector. 5.2 Inserts The insert carrying the optical contacts shall be in hard material and have a cross section and radii such
38、 that no cracks, flaking or breaks can occur in normal operation. The insert for contacts shall be non-removable; it shall be mechanically held in the housing. Sealing shall be provided between the housing and insert. The mechanical contacts retention system shall be integrated in the hard insert. T
39、he design shall permit individual installation of the contacts without removal of the connector. Fitting and removal of the contacts shall be from the rear. For ease of operation, tools as per MIL-I-81969/1-03 standard (P/N for size 16) may be used. Contact position identification shall be permanent
40、 and contrasted on the rear and the front face of the insert or grommet. The female insert (mounted into the plug connector), including the sleeve holder, shall incorporate two alignment pins for multiway connectors. The male insert (mounted into the receptacle connector) shall incorporate two align
41、ment holes for multiway connectors. prEN 4645-001:2008 7 5.3 Removable sleeve holder The removable sleeve holder must be assembled onto the plug connector. 6 Definition drawings and masses The general dimensions and the masses of receptacles, plugs and protective covers are given in the product stan
