10、46-001 : 2001 O Introduction This family of connectors is derived from MIL-C-26482G, series 2, the NAS 1599 bayonet connector with which it is intermateable and which uses MIL-C-39029D for the contacts. It is particularly suitable for use on aircraft applying EN 2282. These connectors are distinguis

11、hable from MIL-C-26482G and NAS 1599 by: - being of a lower mass; - having reduced dimensions; - accepting smaller cables. 1 Scope This standard specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programmes and groups for ba

12、yonet coupling circular connectors, intended for use in an operating temperature range of - 65 “C to 175 “C or 200 “C continuous according to the class and models. 2 Norm ative references This European Standard incorporates by dated or undated reference, provisions from other publications.

24、on the service conditions. These connectors use crimp or solder contacts of sizes 20, 16 and 12. The receptacles and plugs contain either male contacts or female contacts. The contacts fitted in the model Y receptacles are exclusively of the male non removable solder type. The connectors are polariz

25、ed by means of keyways and keys. When all the male contacts are in place, polarization is obtained by different angular positions of the insulator in relation to the main slot or locking key and shall occur before the coupling ring can carry out its function. The visual check of coupling is obtained

26、 by viewing the locking pins through the inspection holes in the coupling ring of the plug. 4.2 Receptacle The receptacle may be attached by: - square flange; - nut, with sealing by O-ring at the attachment; - round soldered or brazed flange for model Y connectors. The receptacle contains five keywa

27、ys 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 angular positions of the inserts. 4.3 Plug The plug contains five keys which engage in the keyways of the receptacle. The main key is wider than the others. Polari

28、zation is ensured by the different angular position of the inserts. The coupling ring permanently fitted on the plug enables the connectors to be coupled and uncoupled. The internal guides of the coupling ring may be treated with a suitable lubricant compatible with the performance required in this

29、standard. The plug of models RS and WS is fitted with a grounding spring device ensuring electrical continuity between the coupled connector housings. 3) Published by: Department of Defense (DOD), the Pentagon, Washington, DC 20301, USA 4) Published by: Aerospace Industries Association of America, I

32、. 4.4.2 Housings The material of the housing for the connectors and for the fittings may either be passivated stainless steel or light alloy protected against corrosion by nickel or black anodized cadmium plating (see EN 3646-002). 4.4.3 Contact s Unless otherwise specified, the contacts shall be in

33、 ferrous alloy for models Y 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 to ensure that performance is respected. Measurement of the thickness of the protective treatment shall be ef

34、fected in accordance with IS0 4524-1. 4.4.4 Non-metallic materials The materials used for insert, seals and grommets shall have a hardness and mechanical and electrical characteristics consistent with the required use. 5 Design 5.1 Housings The connector housings shall be in one unit. At the rear of

35、 the connector housing there shall be either three teeth at 120“ intervals or teeth around the entire periphery. These teeth shall accomodate back shells or other fittings. The receptacle shall furthermore be fitted with an O-ring seal for sealing the coupled housings. Receptacles for attachment by

36、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 in the right and disengage when it is turned an

37、ticlockwise. The coupling ring shall be knurled . The rear fittings shall compress the grommet of the connectors without twisting it. 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 o

38、ccur 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 o

39、f 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 3646-002 and shall not be removable. The mechanical contacts retention system shall be integrated in the hard insert. The design of non-hermetic connectors s

40、hall 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.
