21、nts are provided 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 solde
22、r 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 4. The visual check of coupling is obt
23、ained by 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.

STD-AECMA PREN 40b7-001-ENGL 1777 LOL231L DOL33b7 47-7 Page 5 prEN 4067-001 : 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 co
25、nnectors. The receptacle contains five keyways in which the keys of the plug engage. The main keyway is fixed and 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 Pl
26、ug 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 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 fitte
27、d on the plug enables the connectors to be coupled and uncoupled. The screwing up torque shall be lower than the 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 fit
28、ted with a grounding spring device ensuring electrical continuity between the coupled connector housings. 4.3 Materials 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
29、(see EN 31971. 4.3.1 Housings The material of the housing for the connectors and for the fittings shall be passivated 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
30、 be gold-plated on an appropriate undercoat. Selective protection is authorized provided that it is sufficient to 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
31、for insert, seals and grommets shall have a hardness and mechanical and electrical characteristics consistent with the required use.

32、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 by nut shall contain an O-ring seal. The nut shall have holes for the passage of lock
33、ing 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 coupling threads may have a lubricant applied during manufacture. On completion of t
34、ightening 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 accessories shall compress the grommet of the connectors without twisting it. A blue colour b
35、and 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; - on the coupling ring of the plugs. The position of the colour bands shall be such
36、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 section and radii such that no cracks, flaking or breaks can occur in normal operation.
37、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
38、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 in the hard insert. The design of non-hermetic connectors shall permit individual in
39、stallation 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 masses The general dimensions and the masses of receptacles and plugs are given in the
40、product standards. 6.1 Receptacle mating dimensions The mating dimensions of receptacles are shown in figure 1 and details A, B, C and D as well as in tables 1 and 2.
