29、0B, Department of Defense interface standard: insert arrangements for 1)3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 2591-100 apply. 4 Description 4.1 General Different variants of materials, housings and contact arrangements are provided according

30、 to the classes depending on the service conditions. The pair of connectors is characterized: by shell to shell bottoming; by its triple threaded and self-locking coupling system; by plugs with shielding ring providing protection against radioelectrical interference; by the scoop-proof shells. These

31、 connectors use the following contacts: crimped sizes 22, 20, 16, 12, 10 and 8; soldered (model Y) sizes 22, 20, 16 and 12; coaxial crimped or soldered sizes 16, 12 and 8; For arrangements comprising the letter G or Q, all contacts are grounded to the receptacle housing triaxial crimped or soldered

32、size 8; quadrax crimped size 8. The receptacles and plugs contain either male contacts or female contacts. The contacts fitted in the class Y receptacles are exclusively of the male solder type. The connectors are polarized by means of keyways and keys; polarization shall be obtained before the male

33、 contacts enter the insert of the female contacts and before the coupling ring is engaged. The position of the keying arrangement is given in Table 5. The visual check of coupling is obtained by masking of a red colour band on the receptacle. 4.2 Receptacle The receptacle housing may be attached: sq

34、uare flange; nut, with sealing by O-ring at the attachment; round soldered or brazed flange for class Y connectors. BS EN 3645-001:2015EN 3645-001:2015 (E) 7 4.3 Plug The coupling ring is permanently fitted to the plug and allows coupling and uncoupling of the connectors. The lanyard release version

35、 may also be uncoupled by pulling on the lanyard. The plug is fitted with a self-locking mechanism and a grounding spring device ensuring electrical continuity between the coupled connector housings. An anti-decoupling device shall be provided to maintain complete coupling. 4.4 Materials and surface

36、 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 Housing The material of the housings for the connectors and fittings may be either aluminium all

37、oy, passivated stainless steel or composite. Aluminium alloy and composite shall be plated as defined by the class (composite coupling rings and Hex nut may be unplated) (see EN 3645-002). 4.4.3 Contacts Unless otherwise specified, the non-removable contacts shall be in ferrous alloy for class Y and

38、 in copper alloy for the other classes. They shall be gold-plated on an appropriate undercoat. Selective protection is authorized provided that it is sufficient to ensure that the specified performance is achieved. Measurement of the thickness of the protective plating shall be effected in accordanc

39、e with ISO 4524-1. For removable contacts, see EN 3645-002. 4.4.4 Non-metallic materials The materials used for insert, seals and grommets shall have a hardness and mechanical and electrical characteristics consistent with the required use. 5 Design 5.1 Housings The connector housings shall be one-p

40、iece. They shall contain teeth at the rear over their entire periphery and shall accommodate the rear accessories. The receptacle shall be fitted with a seal for sealing the coupled housings. Jam-nut receptacles shall contain an O-ring seal. The nut shall have holes for the passage of locking wire.

41、During coupling the grounding spring shall be engaged a minimum of 1,02 mm in the receptacle before the contacts engage. Except for the triple start threads, which shall conform to standard MIL-STD-1373, threads shall conform to standards ISO 68-1, ISO 261, ISO 262 and ISO 965-2. BS EN 3645-001:2015

42、EN 3645-001:2015 (E) 8 The coupling ring shall be designed so that the male and female contacts engage when it is turned in a clockwise direction and disengage when turned anticlockwise. The coupling threads may have a lubricant applied during manufacture. Full locking of the connectors shall occur

43、at about 360. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and plug housings. A red band shall be located on the receptacle so as to be visible when unmated and fully covered when completely mated. The receptacle has five keyways which engag

44、e with corresponding keys on the plug. The major key is fixed and is wider than the others. Polarization is ensured by the different positions which the minor keys may take. The position of the insert is fixed relative to the major key. A blue-coloured band indicating that the crimped contacts of th

45、e connectors are rear-releasable shall be provided: in front of the flange on square flange receptacles; on the flange of jam-nut receptacles; on the coupling ring of plugs. This band shall be positioned so that at least one is visible when the connectors are fitted and when they are mated or unmate

46、d. Hermetic receptacles do not require blue colour band. 5.2 Inserts 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 front face of the insert shall be such that sealing is ensured when the con

47、nectors are coupled. The interfacial seal of the insert of the male contacts shall be bonded on the hard insert. The grommet shall permit sealing for all cable diameters indicated in EN 3645-002 and shall not be removable. The mechanical contacts retention system shall be integrated in the hard inse

48、rt. The design of non-hermetic connectors shall permit individual installation of the contacts without removal of the insert or grommet. Fitting and removal of the contacts shall be from the rear with the tools specified in the contact product standards. Contact position identification shall be perm

49、anent and contrasted on the front face of the insert or the interfacial seal and on the rear face of the grommet as indicated in 6.6. The marking shall not be recessed or raised on the surfaces providing a seal. 6 Definition drawings and masses 6.1 General The general dimensions and the masses of receptacles, plugs and protective covers are given in the product standards.
