33、describe optical connector arrangements for plug and receptacle housings. Plug and receptacle housings conform to EN 3645-001 standard. The connectors use rear removable optical contacts with a ferrule diameter of 1,25 mm. The receptacles connector with male arrangement as specified EN 4645-003 and
34、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 the female arrangement. It is considered as a part of the female arrangement (spec
35、ific design per manufacturer). The sleeve holder can be supplied separately only for repair purpose. The connectors 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 posit
36、ion of the keying arrangement is given in EN 3645-001. The visual check of coupling is obtained by masking of a red coloured band on the receptacle. 4.2 Receptacle The receptacle may be attached by: 2) Published by: Department of Defense (DoD), the Pentagon, Washington, DC 20301, USA. BS EN 4645-001
37、:2010EN 4645-001:2010 (E) 7 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 the secondary keyways may take. The position of the insert is
38、 fixed relative to the main keyway. 4.3 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 take. The position of the insert is fixed relative to the mai
39、n 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 lubricant compatible with the performance required in this st
40、andard. 4.4 Materials and surface treatment 4.4.1 General 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). 4.4.2 Housings The material of the connector housings and fittings sh
41、all be of suitable material protected against corrosion by passivation, nickel or cadmium plating (see EN 3197) as specified in the product standard. 4.4.3 Optical contacts and alignment sleeves The material of the optical contacts and alignment sleeves shall be of suitable materials as specified in
42、 the product standard. The optical contacts in both plug and receptacle are sprung-loaded. The spring force is defined in the product standard. 4.4.4 Metallic or non-metallic materials The materials used for insert, seals and grommets shall have hardness and mechanical characteristics consistent wit
43、h 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 rear over the entire periphery and shall accommodate the cable outl
44、ets and other fittings. The receptacle shall be fitted with a seal for sealing the coupled housings. BS EN 4645-001:2010EN 4645-001:2010 (E) 8 The jam nut receptacle housing shall contain an O-ring seal (panel seal). The lock nut shall be provided with wire locking holes. Threads shall conform to st
45、andards 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 when it is unscrewed counter
46、 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 of a red colour band on th
47、e 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 that no cracks, flaking
48、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. The design shall permit in
49、dividual 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 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 con
