25、ct arrangements are provided according to the models depending on the service conditions. The pair of connectors is characterized: - by the mechanical stop of the shells on the coupling; - by its triple threaded and self-locking coupling system; - by plugs with shielding ring providing protection ag

26、ainst radioelectrical interference; - by the scoop-proof shells. These connectors use the following contacts: - crimped sizes 22, 20, 16, 12 and 10, - soldered (model Y) sizes 22, 20, 16 and 12, For arrangements comprising the letter GI all contacts are grounded to the receptacle ho us in g - coaxia

27、l crimped or soldered sizes 16, 12 and 8, - triaxial crimped or soldered size 8. The receptacles and plugs contain either male contacts or female contacts. The contacts fitted in the model Y receptacles are exclusively of the male solder type. The connectors are polarized by means of keyways and key

28、s; polarization shall be 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 table 5. The visual check of coupling is obtained by masking of a red colour band on the receptacle. 2) Publi

31、ng at the attachment; - round soldered or brazed flange for model Y connectors. 4.3 Plug The coupling ring is permanently fitted to the plug and allows coupling and uncoupling of the connectors. The lanyard release version may also be uncoupled by pulling on the lanyard. The plug is fitted with a se

32、lf-locking mechanism and a grounding spring device ensuring electrical continuity between the coupled connector housings. 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

33、the cell not to exceed 0,25 V (see EN 3197). 4.4.2 Housings The material of the housings for the connectors and fittings may be either aluminium alloy, passivated stainless steel or composite. Aluminium alloy and composite shall be plated as defined by the model (composite coupling rings may be unpl

34、ated) (see EN 3645-002). 4.4.3 Contacts Unless otherwise specified, the non-removable contacts shall be in ferrous alloy for models Y and in copper alloy for the other models. They shall be gold-plated on an appropriate undercoat. Selective protection is authorized provided that it is sufficient to

35、ensure that the specified performance is achieved. Measurement of the thickness of the protective plating shall be effected in accordance with IS0 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

36、mechanical and electrical characteristics consistent with the required use. 5 Design 5.1 The connector housings shall be one-piece. They shall contain teeth at the rear over their entire periphery and shall accomodate the rear accessories. The receptacle shall be fitted with a seal for sealing the c

37、oupled housings. Jam nut receptacles shall contain an O-ring seal. The nut shall have holes for the passage of locking wire. 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 confo

38、rm to standard MIL-STD-1373, threads shall conform to standards IS0 68-1, IS0 261, IS0 262 and IS0 965-2.

39、se from IHS-,-,-Page 6 prEN 3645-001: 2002 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 con

40、nectors shall occur at about 360“. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and plug housings. Masking of a red colour band on the receptacle by the coupling nut shall show that the connectors are correctly coupled. The receptacle has fi

41、ve keyways which engage 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

42、crimped contacts of the 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 w

43、hen they are mated or unmated. 5.2 Inserts The insert carrying the male and female contacts shall be in hard material and have a cross section and radii such that no cracks, flaking or breaks can occur in normal operation. provided between the housing and insert. The front face of the insert shall b

44、e such that sealing is ensured when the connectors 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

45、system shall be integrated in the hard insert. 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. Co

46、ntact position identification shall be permanent and contrasted on the front face of the insert or the interfacial seal and on the rear face of the grommet as indicated in 6.5.
