EN 4639-001:20075 4 Description 4.1 General This document
26、 describes an optical connector module to be installed in plug and receptacle housings. Plug and receptacle housings conform to EN 4644-001. There are two sizes of connector housings: Housing size 1 with 1 module cavity. Housing size 2 with 2 module cavities. The connectors use rear removable optica
27、l contacts with a ferrule diameter of 1,25 mm. The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder. The receptacles and plugs contain either male or female module. The female module is characterised by its ability to receive the remova
28、ble sleeve holder. The modules can be installed and removed from the shell by means of a tool as specified in EN 4644-003. The modules are keyed to prevent mismatching (“A” module for connector housing cavity “A” and “B” module for connector housing cavity “B”) as specified in EN 4644-001. The conne
29、ctors are keyed as specified in EN 4644-001. Connector type designation as specified in EN 4644-001. 4.2 Receptacle Receptacle description as specified EN 4644-001. 4.3 Plug Plug description as specified EN 4644-001. 4.4 Materials and surface treatment 4.4.1 General When dissimilar metals are in clo
30、se 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 specified in EN 4644-001. 4.4.3 Optical contacts and alignment sleeves The contacts shall be of suitable mat
31、erials as specified in the product standard. The optical alignment sleeves shall be of suitable materials as specified in the product standard. The optical contacts are spring-loaded. The spring force is defined in the product standard. EN 4639-001:20076 4.4.4 Metallic or non-metallic materials The
32、materials used for modules, 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 EN 4644-001. 5.2 Modules The modules carrying the optical contacts shall be in hard material and hav
33、e a cross section and radii such that no cracks, flaking or breaks can occur in normal operation. The contact module is mechanically held in the connector housing by retention clips, and removable with the use of an extraction tool. The mechanical contacts retention system shall be integrated in the
34、 hard module. The front face of the module shall be such that sealing is ensured when the connectors are coupled. The interfacial seal of the module of the male contacts shall be permanently fastened on the hard module. Sealing of the rear face of the module is provided by a grommet adapted to the e
35、xternal diameter of the cable. The design shall permit individual installation of the contacts without removal of the module. Installation and removal of the contacts shall be from the rear. For ease of operation, tools as per MIL-I-81969/14-03 standard (P/N for size 16) may be used. Contact positio
36、n identification 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 E
