EN 3646-001:2015 (E) 4 Introduction This family of connectors is derived from MIL-DTL-26482, series 2, the NAS 1599 bayonet connector with which it is intermateable and which uses AS-39029 for the contacts. It is particularly suitable for use on aircraft applying EN 2282. These connectors are distinguishable from MIL-DTL-26482 and NAS 1599 by: — being of a lower mass; — having reduced dimensions; — accepting smaller cables. SIST EN 3646-001:2016



EN 3646-001:2015 (E) 5 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 bayonet 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 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 3646-001:2015 (E) 6 4 Description 4.1 General Different variants of materials, housings and contact arrangements are provided according to the models depending on the service conditions. These connectors use crimp or solder contacts of size 20, size 16 and size 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 polarized 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 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 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 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. Polarization 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 standard. The plug of models 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 different 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 light alloy protected against corrosion by nickel, black anodized or cadmium plating (see EN 3646-002). SIST EN 3646-001:2016



EN 3646-001:2015 (E) 7 4.4.3 Contacts Unless otherwise specified, the contacts shall be in 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 effected in accordance with ISO 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 the connector housing there shall be either three teeth at 120° intervals or teeth around the entire periphery. These teeth shall accommodate cable outlets or other fittings. 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 turned clockwise and disengaged when it is turned counter-clockwise. The coupling ring shall be knurled. The cable outlets shall compress the connector grommets without distorting 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 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 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 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 contact product standards. SIST EN 3646-001:2016
