It is suit
11、able 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 outside diameter. 1 Scope This standard specifies the general characteristics, the conditions for qu
12、alification, 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 indispensable for the application of this document.

17、sings. 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 opt
18、ical 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 removable sleeve holder. The inserts can be installed and removed from the shell by m
19、ean of 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

21、 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 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 a
22、lignment 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. prEN 4639-001:20065 4.4.4 Metallic or non-metallic materials The materials used for modules, seals and grommets shall hav
23、e a hardness and mechanical characteristics consistent with the required use. 5 Design 5.1 Housing The connector 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, fl
24、aking 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 hard module. The front face of the module shall be
25、 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 external diameter of the cable The design shall perm
26、it individual installation of the contacts without removal of the module. Fitting 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 position identification shall be permanent and contrasted on the
27、 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 EN EPX-xxx (GT3). 6.3 Plug All housing dimensions are defi
