EN 2997-001:2017 (E) 4 Introduction This family of connectors is derived from MIL-DTL-83723 series III, type T which it is intermateable with. It is particularly suitable for use on aircraft engines and in zones of severe environmental conditions on board aircraft, applying EN 2282. These connectors are distinguishable from MIL-DTL-83723 by: a) the mechanical stop for coupling being achieved manually; b) the coupling system having a self-locking nut that features a greater resistance to decoupling; c) the variety of the functional classes and models, including models with integrated cable outlets. SIST EN 2997-001:2017



EN 2997-001:2017 (E) 5 1 Scope This European Standard specifies the general characteristics, the conditions for qualification acceptance and quality assurance, and the test programs and groups for threaded ring coupling circular connectors, fire resistant or non-fire resistant, intended for use in a temperature range from − 65 °C to 175 °C continuous, 200 °C continuous or 260 °C peak according to the classes and models. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

These connectors use crimp or solder contacts of sizes 22, 20, 16 and 12. The receptacles and plugs contain either male contacts or female contacts. The contacts fitted in the classes Y and YE receptacles are exclusively of the male non-removable solder type. The connectors are polarized by means of keyways and keys; 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. Masking of the blue colour band on the receptacle provides visual indication of full coupling. Only the connectors housing sizes 8, 10 and 12 with size 22 contacts are mechanical scoop proof.

EN 2997-001:2017 (E) 7 4.2 Receptacle The receptacle may be attached by: • square flange; • the jam-nut with O-ring sealing; for spare parts, see EN 2997-002; • round flange for attachment by soldering/brazing/welding, classes Y and YE only. The receptacle contains five keyways into which the keys of the plug engage. The main keyway is fixed and is wider than the others. Polarization is ensured by different positions of the secondary keyways. The position of the insert is 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 different positions of the secondary keys. 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 coupling torque shall be at least 50 % lower than the uncoupling torque. The internal thread of the coupling ring may be treated during manufacture with a suitable lubricant compatible with the performance required in this standard. The plug of classes S, SE, SF, SV, RS and WS is fitted with 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 the cell not to exceed 0,25 V (see EN 3197). 4.4.2 Housings The material of the housing for the connectors and for the fittings may either be passivated stainless steel or aluminium alloy protected against corrosion by nickel or cadmium plating (see EN 2997-002). 4.4.3 Contacts Unless otherwise specified, the contacts shall be in ferrous alloy for classes Y and YE and in copper alloy for the other models. The contacts for classes Y and YE shall be gold-plated on an appropriate undercoat (silver undercoat shall not be used). Selective protection is authorized provided that it is sufficient to ensure that performance is not affected. Measurement of the thickness of the protective treatment shall be effected in accordance with EN 2591-508. For removable contacts, see EN 2997-002. SIST EN 2997-001:2017



EN 2997-001:2017 (E) 8 4.4.4 Non-metallic materials The materials used for insert, seals and grommets shall have hardness and mechanical and electrical characteristics consistent with the required use. 5 Design 5.1 Housings The connector housings shall be in one unit. They shall contain teeth at the rear over the entire periphery and shall accommodate the cable outlet accessory and other fittings except for connectors with integrated cable outlet. The receptacle shall furthermore be fitted with an O-ring 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. The threads shall conform to ISO 263. The coupling ring shall be designed so that the male and female contacts engage when it is rotated clockwise and disengage when it is rotated anti clockwise. The coupling ring shall be knurled to aid gripping by hand. On completion of tightening of the coupling ring, mechanical metal to metal contact shall exist between the receptacle and the plug mating faces, indicated by masking of the blue colour band (see Figure 1). The cable outlet accessories shall compress the grommet of the connectors without twisting it. A blue colour band indicating that the crimp contacts of the connectors are intended for rear removal shall be provided: • behind the flange of the receptacles with square flange; • on the flange of receptacles with jam nut attachment; • on the coupling ring of the plugs. The position of the blue colour bands shall be such that at least one of them is visible at all times on the coupling ring of the plug. 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 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 2997-002 and shall not be removable. SIST EN 2997-001:2017



EN 2997-001:2017 (E) 9 The mechanical contacts 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. Insertion and removal of the contacts shall be from the rear with the tools specified in the product standards. 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. 6.2 Receptacle mating dimensions The mating dimensions of receptacles are shown in Figures 1 and 2 including details A, B, C and D as well as in Tables 1 and 2.

6.6 Contact arrangements The contact arrangements in the inserts are specified by Figures 10 to 44, which show the front face of the female inserts. The following tolerances apply to the inserts fitted in the housings (A and B reference Figure 5): • centre of each hole:  ∅ 0,36 A B
• centre of each contact end:  ∅ 0,61 A B
Identification of the contact position shall be permanently applied in contrasting colour on the front face of the insert or interfacial seal and on the rear face of the wire sealing grommet. Identification shall not be recessed or raised on the sealing surfaces. Symbols for contact sizes are given in EN 3155-001. Housing sizes and contact arrangements (see Figures 10 to 44).
