EN 4531-001:2012 (E) 6 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 2591-100 apply. 4 Description 4.1 General The connectors utilise rear removable optical contacts with a ferrule diameter of 2,5 mm. 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 6.4. The connectors with shell size 9, 11 and 13 are 100 % scoop proof. The visual check of full mating is obtained by masking of a red coloured band on the receptacle. 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 internal thread of the coupling ring may be treated with a suitable lubricant compatible with the performance required in this standard. 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 Shells The material of the connector shells and fittings shall be of suitable material and/or finish to protect against corrosion (see EN 3197) as specified in the product standard.
SIST EN 4531-001:2012
EN 4531-001:2012 (E) 7 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 spring-loaded. The spring force is defined in the product standard. 4.4.4 Metallic or non-metallic materials Insert, seal, grommet and alignment pin materials shall have a hardness and mechanical characteristics consistent with the required use. 5 Design 5.1 Shells The connector shells shall be in one inseparable unit. They contain teeth at the rear over the entire periphery and shall accommodate accessories. The receptacle shall be fitted with an internal seal for a good sealing the coupled shells. The jam nut receptacle shell shall contain an O-ring seal (panel seal). The lock nut shall be provided with wire locking holes. Threads shall conform to standards 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 shell. Sealing shall be provided between the shell and insert. The mechanical contacts retention system shall be integrated in the hard insert. The design shall permit individual installation of the contacts without removal of the insert. Insertion and removal of the contacts shall be from the rear. For ease of operation, tools according to MIL-I-81969/8-10 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 alignment pins improve the guiding of the inserts before optical contacts touch each other. The female insert shall incorporate two optical contact alignment holes for multiway connectors and a guiding sleeve. Under EN 61300-3-33 test conditions, the zirconia sleeve force shall be [1,9 N – 3,5 N]. SIST EN 4531-001:2012
