26、nt describes an optical connector insert to be installed in plug and receptacle housings. Plug and receptacle housings conform to ARINC Specification 600. The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder. The plug connector contain
27、male insert as specified in EN 4640-003. The receptacles connector contain female insert as specified in EN 4640-004. The female insert is composed 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 par
28、t of the female insert (specific design per manufacturer). The sleeve holder can be supplied separately only for repair purpose. The optical contact is in accordance with EN 4639-101. The connectors are keyed as specified in ARINC Specification 600. Connector type designation as specified in ARINC S

31、terials 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 materials used for in
32、serts, 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 in hard materi
33、al 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 external diam
34、eter 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 identification
35、 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 ARINC Specificati
