EN 4531-001:2007 (E) 4 Introduction This family of fibre optic connectors is derived from MIL-DTL-38999K series III and EN 3645-001. It is suitable for use on aerospace onboard applications. It provides easy access for optical contact end face cleaning. The connectors with shell size 9, 11 and 13 are 100 % scoop proof. The optical contacts are capable of accepting single cable sizes up to a maximum of 2,5 mm outside 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 threaded ring coupling circular fibre optic self-locking connectors, fire-resistant or non fire-resistant, intended for use in a temperature range from − 65 °C to 150 °C (cable dependent) continuous. 2 Normative references The following referenced documents are indispensable for the application of this document.

The receptacles and plugs contain either male insert or female insert. The female insert is characterized by its ability to precisely align the optical contacts. The precise alignment of the optical contacts is accomplished by alignment sleeves. The connectors are polarized by means of keyways and keys; polarization is obtained before the male contacts enter the insert of the female contacts and before the coupling ring is engaged. The position of the keying arrangement is given in 6.5. The visual check of full mating is obtained by masking of a red coloured band on the receptacle. Connector accessories are defined in EN 4531-002. 4.2 Receptacle The receptacle contains five keyways in which the keys of the plug engage. The main keyway is fixed and is wider than the others. Polarization is ensured by the different positions which the secondary keyways may take. The position of the insert is fixed relative to the main keyway. 4.3 Plug The plug contains five keys which engage in the keyways of the receptacle. The main key is wider than the others. Polarization is ensured by the different positions which the secondary keys may take. The position of the insert is fixed relative to the main key. The coupling ring permanently fitted on the plug enables the connectors to be mated and unmated. The mating torque shall be lower than the unmating torque. The internal thread of the coupling ring may be treated with a suitable lubricant compatible with the performance required in this standard. SIST EN 4531-001:2009
EN 4531-001:2007 (E) 6 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 material of the connector housings and fittings shall be of suitable material and/or finish to protect against corrosion (see EN 3197) as specified in the product standard.
4.4.3 Optical contacts and alignment sleeves The material of the optical contacts and alignment sleeves shall be of suitable materials as specified in the appropriate product standard. The optical contacts in both plug and receptacle are sprung-loaded. The spring force is defined in the product standard. 4.4.4 Metallic or non-metallic materials The materials used for insert seals, grommets and alignment pins shall have a hardness and mechanical characteristics consistent with the required use. 5 Design 5.1 Housings The connector housings shall be in one unit. They contain teeth at the rear over the entire periphery and shall accommodate the accessories. The receptacle shall be fitted with an internal seal for sealing the coupled housings. The jam nut receptacle housing shall contain an O-ring seal (panel seal). The lock nut shall be provided with wire locking holes. Threads shall conform to ISO 263, except for the triple start threads, which shall conform to standard MIL-STD-1373. The coupling ring shall be designed so that the optical contacts engage when it is screwed clockwise and disengage when it is unscrewed counter clockwise. The coupling ring shall be designed to provide a hand grip profile. Full locking of the connectors shall occur at approximately 360°. On completion of tightening of the coupling ring, mechanical contact shall exist between the receptacle and plug shells. Masking of a red colour band on the receptacle shall show that the connectors are correctly mated. The front face of the plug shell shall seal when fully mated with the receptacle connector. 5.2 Inserts The insert 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 insert for contacts shall be non-removable; it shall be mechanically held in the housing. Sealing shall be provided between the housing and insert. The mechanical contacts retention system shall be integrated in the hard insert. SIST EN 4531-001:2009
EN 4531-001:2007 (E) 7 The design shall permit individual installation of the contacts without removal of the insert. Fitting and removal of the contacts shall be from the rear. For ease of operation, tools as per MIL-I-81969/8B-10 standard (P/N for size 12) may be used. Contact position identification shall be permanent and contrasted on the front face of the insert and on the rear face of the insert or grommet. The male insert shall incorporate two optical contact alignment pins for multiway connectors. The female insert shall incorporate two optical contact alignment holes for multiway connectors. 6 Definition drawings and masses 6.1 General The general dimensions and the masses of receptacles, plugs and protective covers are given in the product standards. 6.2 Receptacle mating dimensions 6.2.1 Receptacle with male insert The mating dimensions of receptacles with the male insert are shown in Figure 1 for shell sizes 11, 13, 17, 21, and 25, Figure 2 for shell size 09 and in Table 1.
