BS EN 4626-001:2008EN 4626-001:2008 (E) 4 Introduction This family of fibre optic contact sub-assemblies are suitable for use in ARINC 600 connectors with size 8 Quadrax cavities in aerospace onboard applications. It provides easy acc
18、ess for optical contact end face cleaning. 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 fibre sub-assembly contact in rack and panel connectors, intended for use in a tempe
19、rature range from 65 C to 125 C continuous (cable dependent). This standard specifies a pair of adaptors to fit with standard Quadrax cavities and EN 4531-101 optical contact. 2 Normative references The following referenced documents are indispensable for the application of this document.

BS EN 4626-001:2008EN 4626-001:2008 (E) 5 4 Description 4.1 Optical sub-assembly and adaptor The optical sub-assembly comprises of an EN 4531-101 fibre optic contact, male an
25、d female adaptors allowing 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 optica
26、l ferrules. The optical 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
27、 force of the cell not 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 a
28、daptor shall be of suitable 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 desi
29、gned to provide mechanical 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 individu
30、al adaptors and contacts without removal of the connertor insert. Fitting and removal of the adaptor will be from the rear of the connector insert using the tool specified in the relevant adaptor product standard.
