20、:20074 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 2591-100 apply. 4 Description 4.1 General This document describes an optical connector insert to be installed in plug and receptacle housings. Plug and receptacle housings conform to ARINC Specifi
21、cation 600. The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder. The plug connector contain male insert as specified in EN 4640-003. The receptacles connector contain female insert as specified in EN 4640-004. The female insert is comp
22、osed of an insert and a removable sleeve holder as specified in EN 4640-004. The sleeve holder is delivered with the female insert. It is considered as a part of the female insert (specific design per manufacturer). The sleeve holder can be supplied separately only for repair purpose. The optical co
23、ntact is in accordance with EN 4639-101. The connectors are keyed as specified in ARINC Specification 600. Connector type designation as specified in ARINC Specification 600. 4.2 Receptacle Receptacle description as specified in ARINC Specification 600. 4.3 Plug Plug description as specified in ARIN
24、C Specification 600. 4.4 Materials and surface treatment 4.4.1 General 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 (see EN 3197). 4.4.2 Housings The connector housing description as spec

26、of suitable materials as specified in EN 4639-101. The optical alignment sleeves shall be of suitable materials as specified in EN 4640-002. The optical contacts are sprung-loaded. The spring force is defined in the product standard (EN 4639-101). 4.4.4 Metallic or non-metallic materials The materia
27、ls used for inserts, seals and grommets shall have a hardness and mechanical characteristics consistent with the required use. 5 Design 5.1 Housing The connector housing design as specified in ARINC Specification 600. 5.2 Connector inserts The connector insert carrying the optical contacts shall be
28、in hard material and have a cross section and radii such that no cracks, flaking or breaks can occur in normal operation. The mechanical contacts retention system shall be integrated in the connector insert. Sealing of the rear face of the connector insert can be provided by a grommet adapted to the
29、 external diameter of the cable The design shall permit individual installation of the contacts without removal of the connector insert. Fitting and removal of the contacts shall be from the rear. For ease of operation, tools as per MIL-I-81969/14-03 (P/N for size 16) may be used. Contact position i
30、dentification shall be permanent and contrasted on the rear face of the insert or grommet. 6 Definition drawings 6.1 General The general dimensions and the masses of receptacles, plugs and protective covers are given in the product standards. 6.2 Receptacle All housing dimensions are defined in ARIN
