The coupling system is the screw type; at th
26、e end of coupling the housings are mechanically stopped. 4.2 Receptacle Fixing is by nut, anti-vibration washer and gasket seal. 4.3 Plug The knurled coupling ring mounted permanently on the plug allows the connectors to be coupled and decoupled. 4.4 Materials and surface treatment When dissimilar m
27、etals are in close contact, adequate protection against corrosion shall be used to ensure that the electro-chemical potential difference does not exceed 0,25 V. a) Housing Copper alloy, tin plated. b) Contact Copper alloy, gold-plated over an appropriate undercoat. c) Insert The materials used shall
28、 have electrical and mechanical characteristics compatible with the required use. d) Ferrule Material identical to that used for housing. 5 Design The insert is not removable. 4) Published by Society of Automotive Engineers Inc.
