3.2 receptacle accessory having socket contact(s) designed to engage with the pin(s) of a plug, incorporating means for the electrical connection and insulated mechanical casting for retention of cables and wires 3.3 type test conformity test made on one or more items representative of the production 3.4 production test test that is carried out for samples of certain lot according to ISO 2859-1 3.5 class A connecting device accessory that is completed by insulating material moulded around pre-assembled components that are terminated to cable(s) or wire(s) in factory 3.6 class B connecting device accessory consisting of a pre-moulded housing and interface contacts that are meant to be assembled on the field 3.7 primary circuit electric circuit that transfers energy from a power source to the primary winding of an AGL transformer 3.8 secondary circuit electric circuit that transfers energy from the secondary winding of the AGL transformer to a load 3.9 screen continuity conductor copper wire used to make a connection to the screen of a cable for the purpose of continuity or earthing 4 General requirements Plugs and receptacles shall be so designed and constructed that, in normal use, their performance is reliable, and safety is achieved by reducing risk to a tolerable level in airfield environment. Compliance is checked by meeting all the relevant requirements and tests specified in this document.
8 Marking and documentation 8.1 Connecting devices shall be marked with manufacturer’s name, product identification or catalogue number, style and type reference of a product. Compliance is checked by inspection. 8.2 Markings shall be readily visible. Minimum height of letters/symbols shall be 3 mm. Compliance is checked by inspection. 8.3 Markings shall be made impression, moulding, pressing or engraving or any other method that provides legibility over life time of the product. Compliance is checked by inspection.
11.2 Screen continuity conductor can be insulated or bare. 11.3 Minimum cross-section area of screen continuity conductors shall be at least 2,5 mm 2 . Compliance of 11.1 to 11.3 is checked by inspection. 11.4 The connection between the screen and the screen continuity conductor shall be of low resistance. The total voltage drop across the clamping unit from screen to continuity conductor shall be less than 7,5 mV at a current of 6,6 A. Compliance is checked by the following test. Test current of 6,6 A shall be passed from the screen through the clamping unit to the earthing continuity conductor (as close as possible to the clamping unit) for a minimum of 5 min. At the end of that period the voltage drop shall be less than 7,5 mV. 12 Terminations of conductors 12.1 General Conductors shall be connected to connecting devices with terminations (welded, soldered, crimped). Crimped connections shall fulfil the requirements of IEC 60352-2. NOTE Table 1 of IEC 60352-2:2006 gives separation forces and Clause 7 gives tool information. Screw terminals, screwless terminals or spring loaded terminals for main conductors shall not be used. 12.2 Terminations for connecting devices which are attached to conductor(s) on the field Connecting devices shall have provisions for crimping.
13 Construction of connecting device and their assemblies 13.1 Housing The plug/receptacle housing interface shall conform to the dimensional and construction requirements as indicated on the applicable Table 2 and Table 3. For field attached connect kits the housing plug/receptacle interface shall comply with dimension of Table 2 and Table 3 as indicated. The connecting device housing/encapsulation shall fully enclose the pins of the plug and sockets of the receptacle of the engaged assembly except for the mating interface surfaces. The material shall comply with the environmental criteria of IEC 61820-1. Interface surfaces of connecting devices shall be smooth (shall be free of parting lines) and perpendicular in order to ensure water tightness when plug and receptacle are connected together. Compliance is checked by test of 14.2. 13.2 Pins and sockets The pins and sockets shall conform to the dimensional and construction requirements as indicated on the applicable Table 2 and Table 3. The sockets shall be slotted and have sufficient contact pressure to ensure good electrical contact as required by 15.4. Pins and sockets shall be made of materials that contain at least 60 % copper. For field attached connecting devices, the contact shall be annealed in the crimp area to prevent fracturing the crimp barrel during installation. The remainder of the contact shall remain at its original hardness. The pin and socket shall be electroplated with tin or other suitable material to provide good electrical contact and corrosion resistance as required by 15.4. Compliance is checked by inspection.
