EN 3372-001:2007 (E) 4 Introduction This family of connectors is similar to MIL-DTL-38999 series I, with which it is not intermateable or inter-mountable. 1 Scope This standard specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups. These bayonet coupling, scoop-proof, medium and high density connectors are suitable for operating temperatures − 65 °C to 175 °C continuous or 200 °C continuous according to class and model. 2 Normative references The following referenced documents are indispensable for the application of this document.

These connectors use crimp or solder contacts of sizes 22, 20, 16, 12 and 8. The receptacles and plugs contain either male or female contacts. The contacts fitted in the class Y receptacles are exclusively of the male solder type. For arrangements comprising the letter G, some contacts are grounded to the receptacle housing. The connectors are polarised by means of keyways and keys; polarisation 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 4.

EN 3372-001:2007 (E) 6 The visual check of coupling is obtained by the appearance of the ends of the bayonet pins (blue) through the coupling ring on the plug. 4.2 Receptacle The receptacle fixing may be attached by: square flange; jam nut, with sealing by O-ring at the attachment; round flange for attachment by soldering/brazing/welding. Class Y only. The receptacle contains five keyways into which the keys of the plug engage. The secondary keyways are fixed and are narrower than the main keyway. Polarisation is ensured by different angular positions of the main keyway in relation to the secondary keyways. The position of the insert is fixed relative to the secondary keyways. 4.3 Plug The plug contains five keys that engage in the keyways of the receptacle. The main key is wider than the oth-ers. Polarisation is ensured by different angular positions of the main key in relation to the secondary keys. The position of the insert is fixed relative to the secondary keys. The coupling ring is permanently fitted to the plug and enables the connectors to be coupled and uncoupled. The internal guides of the coupling ring may be treated during manufacture with a suitable lubricant compa-tible with the performance required by this standard. The plug is fitted with a grounding spring device, which ensures electrical continuity between coupled connec-tor housings. 4.4 Materials and surface treatment 4.4.1 General When different metals are in close contact, protection against shall be ensured. The electromotive force of the cell shall not 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 or passivated stainless steel. Aluminium alloy shall be plated by the class (see EN 3372-002). 4.4.3 Contacts Unless otherwise specified, contacts shall be in ferrous alloy for classes Y and in copper alloy for other classes. They shall be gold-plated on an appropriate undercoat. Selective protection is authorised provided that it is sufficient to ensure that the specified performance is achieved. The use of silver undercoats is prohibited. Measurement of the thickness of the protective plating shall be effected in accordance with ISO 4524-1 (Class Y). For removable contacts see EN 3372-002. SIST EN 3372-001:2009
EN 3372-001:2007 (E) 7 4.4.4 Non-metallic materials The materials used for the inserts, seals and grommets shall have hardness, electrical and mechanical characteristics compatible with the required use. 5 Design 5.1 Housings The connector housings shall be in one unit. The rear of the connector shall contain teeth over its entire pe-riphery that accommodates the rear accessories. The receptacle shall be equipped with a seal for sealing the coupled housings. Receptacles for attachment by nut 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. Threads shall conform to standard ISO 263, Class 2a. The coupling ring shall be designed so that the male and female contacts engage when it is turned in a clock-wise direction and disengage when it is turned anticlockwise. The coupling ring shall be knurled. Full locking of the connectors shall occur at approximately 120° of rotation. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and plug housings. The appearance of the ends of the bayonet pins, coloured blue, through the plug coupling ring is a visual indication that the con-nectors are correctly mated. 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. 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 connectors are coupled. The inter-facial 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 3372-002 and shall not be remov-able. The mechanical contact retention 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. SIST EN 3372-001:2009
