18、owing positioning of the fibre optic contact in either a plug or receptacle Quadrax size 8 cavity, or a single part which integrates the EN 4531-101 contact and adaptor. The female adaptor is characterised by the integral alignment sleeve providing precise alignment of the optical ferrules. The opti
19、cal contact sub-assemblies are polarized by means of keyways in the adaptors and keys on the contact body. 4.2 Materials and surface treatment 4.2.1 Requirements When dissimilar metals are in close contact, adequate protection against corrosion shall be used for the electromotive force of the cell n
20、ot to exceed 0,25 V (see EN 3197). 4.2.2 Housing and inserts The connector housing and insert arrangement information are detailed in ARINC 600 standards. 4.2.3 Optical contacts Details of the optical contacts and alignment sleeves are detailed in EN 4531-101. 4.2.4 Adaptor The adaptor shall be of s
21、uitable material as specified in the product standard. 5 Design 5.1 Housing Connector housing is defined in the ARINC 600 standard. Quadrax cavity arrangements will be defined in Technical Report in preparation. 5.2 Optical contact See EN 4531-101. 5.3 Adaptor The adaptor is designed to provide mech
22、anical retention, and accurate alignment of the EN 4531-101 fibre optic contact within an ARINC 600 housing containing Quadrax size 8 cavities. The adaptor is keyed and mechanically retained in the ARINC 600 Quadrax size 8 insert cavity. The design permits installation of individual adaptors and con
23、tacts without removal of the connertor insert. Fitting ant removal of the adaptor will be from the rear of the connector insert using the tool specified in the relevant adaptor product standard. prEN 4626-001:20065 5.4 Connector and optical contact coupling sequence During normal coupling the mechan
24、ical properties of the connectors provide the following coupling sequence: Shells Polarizing keys Optical contacts Adaptor. Refer to the ARINC 600 specification for mechanical interconnecting requirements. 6 Drawings 6.1 Definition drawings The general intermateability dimensions of receptacles and
25、plugs are given below. Optical contact dimensions are defined in the product standard. 6.2 Coupling condition The stated dimensions are included to ensure that no mechanical interference occurs between the ferrule of the female adaptor and male adaptor body during the coupling cycle.
