12、 Introduction This family of fibre optic connectors is derived from EN EPX-xxx (GT3). It is suitable for use on aerospace onboard applications. It provides easy access for optical contact end face cleaning. The optical contacts are capable of accepting single cable sizes up to a maximum of 2 mm outs
13、ide diameter. 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 rectangular multipin fibre optic connectors. 2 Normative references The following referenced documents are indisp

19、 Plug and receptacle housings conform to EN EPX-xxx (GT3). 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 optical contacts with a ferrule diameter of 1,25 mm. The precise alignment of the optical c
20、ontacts 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 removable sleeve holder. The inserts can be installed and removed from the shell by mean of
21、 a tool as specified EN EPX-xxx (GT3). The modules are keyed to prevent mismating (“A” module for connector housing cavity “A” and “B” module for connector housing cavity “B.”) as specified EN EPX-xxx (GT3). The connectors are keyed as specified EN EPX-xxx (GT3). Connector type designation as specif
22、ied EN EPX-xxx (GT3). 4.2 Receptacle Receptacle description as specified EN EPX-xxx (GT3). 4.3 Plug Plug description as specified EN EPX-xxx (GT3). 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 t
23、he 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 EPX-xxx (GT3). 4.4.3 Optical contacts and alignment sleeves The contacts shall be of suitable materials as specified in the product standard. The optical alignme
24、nt sleeves shall be of suitable materials as specified in the product standard. The optical contacts are sprung-loaded. The spring force is defined in the product standard.

26、ctor housing design as specified in EN EPX-xxx (GT3). 5.2 Modules The modules carrying the optical contacts shall be in hard material and have 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 hous
27、ing by retention clips, and removable with the use of an extraction tool. The mechanical contacts retention system shall be integrated in the 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 mal
28、e 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 external diameter of the cable The design shall permit individual installation of the contacts without removal of the module. Fitting and removal of the contact
29、s 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 position 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
