BS EN 2997-001:2017EN 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
27、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;
28、 c) the variety of the functional classes and models, including models with integrated cable outlets. BS EN 2997-001:2017EN 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 progra
29、ms 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 i

39、 4 Description 4.1 General Different variants of materials, housings and contact arrangements are provided according to the model and class. 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 contac
40、ts 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
41、 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. 2) Published by: Defense Logistic Agency (DLA), htt

The rec
43、eptacle 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,
44、 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 cou
45、pled 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 W
46、S 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
47、 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, t
48、he 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 th
49、at 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. BS EN 2997-001:2017EN 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
