19、 371 6-001 : 1997 3 Definitions For the purposes of this standard, the definitions given in EN 2591 and EN 31 55-001 apply. 4 Description The triaxial connectors are the solder or crimp contact type, with mechanical end stop. The coupling system is the screw type ; at the end of coupling the housing

20、s are mechanically stopped. 4.1 Receptacle Fixing is by nut, anti-vibration washer and gasket seal. 4.2 Plug The knurled coupling ring mounted permanently on the plug allows the connectors to be coupled and decoupled. 4.3 Materials and surface treatment When dissimilar metals are in close contact, a

21、dequate protection against corrosion shall be used to ensure that the electro-chemical potential difference does not exceed 0,25 V. 4.3.1 Housing Copper alloy, tin plated. 4.3.2 Contact Copper alloy, gold-plated over an appropriate undercoat. 4.3.3 Insert The materials used shall have electrical and

22、 mechanical characteristics compatible with the required use. 4.3.4 Ferrule Material identical to that used for housing. 5 Design The insert is not removable. It is retained mechanically in the housing. The fronts of the inserts are designed to guarantee the seal when the connectors are mated. 6 Def
