10、97 O Introduction This family of connectors is derived from MIL-C-83723 series III type T, EN 2997-001 and MIL-C-39029 for the contacts. 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 d
11、istinguishable from EN 2997-001 by: - the contact protection effectiveness (scoop-proof). 1 Scope This standard specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups for threaded ring coupling circular conne
12、ctors, fire-resistant, intended for use in a temperature range from - 65 OC to 260 OC peak. 2 Normative references This European Standard incorporates by dated or undated reference provisions from others publications. These normative references are cited at the appropriate places in the text and the
13、 publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

23、rovided according to the models depending on the service conditions. These connectors use crimp or solder contacts of sizes 20 and 16. The receptacles and plugs contain either male contacts or female contacts. The contacts fitted in the model YE receptacles are exclusively of the male solder type. T
24、he 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 4. The visual check of coupling is obtained by
25、masking of a blue colour band on the receptacle. 2) Published by: Department of Defense (DODI, the Pentagon, Washington, D.C. 20301 USA. 3) Published by: Society of Automotive Engineers, Inc.

27、067-001 : 1997 4.1 Receptacle The receptacle may be attached by: - square flange; - nut, with sealing by O-ring at the attachment; - round soldered, brazed or welded flange for model YE connectors. The receptacle contains five keyways in which the keys of the plug engage. The main keyway is fixed an
28、d is wider than the others. Polarization is ensured by the different positions which the secondary keyways may take. The position of the insert is fixed relative to the main keyway. 4.2 Plug The plug contains five keys which engage in the keyways of the receptacle. The main key is wider than the oth
29、ers. Polarization is ensured by the different positions which the secondary keys may take. 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 screwing up torque shall be lower than the
30、 unscrewing torque. The internal thread of the coupling ring may be treated with a suitable lubricant compatible with the performance required in this standard. The plug of model SE is fitted with a grounding spring device ensuring electrical continuity between the coupled connector housings. 4.3 Ma
31、terials and surface treatment 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 31971. 4.3.1 Housings The material of the housing for the connectors and for the fittings shall be passi
32、vated stainless steel (see EN 4067-002). 4.3.2 Contacts Unless otherwise specified, the contacts shall be in ferrous alloy for model YE 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 t
33、o ensure that performance is met. Measurement of the thickness of the protective treatment shall be effected in accordance with EN 2591-508. 4.3.3 Nonmetallic materials The materials used for insert, seals and grommets shall have a hardness and mechanical and electrical characteristics consistent wi
34、th the required use.

35、 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 accomodate cable outlet accessories. The receptacle shall furthermore be fitted with an O-ring seal for sealing the coupled housings. Receptacles for attachment
36、by nut shall contain an O-ring seal. The nut shall have holes for the passage of locking wire. The threads shall conform to IS0 263. 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
37、 coupling threads may have a lubricant applied during manufacture. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and the plug. Masking of the colour band (see figure 1) shall show that the connectors are correctly coupled. The outlet accessor
38、ies 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 for nut attachment;
39、 - on the coupling ring of the plugs. The position of the colour bands shall be such that at least one of them is visible when the connectors are fitted and when they are coupled or uncoupled. 5.2 Inserts The insert carrying the male and female contacts shall be in hard material and have a cross sec
40、tion 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 ens
41、ured 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 4067-002 and shall not be removable. The mechanical contacts retention system shall be integrated
42、 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. 6 Definition drawings and ma
43、sses The general dimensions and the masses of receptacles and plugs are given in the product standards.
