This standard replaces the standard previously issued as follows: GB/T 5053.2-1985. Road vehicles - Contactors for the electrical connection of
towing and towed vehicles - 7-pole connector type 12 N
(normal) for vehicles with 12 V nominal supply voltage
1 Scope
This standard specifies the dimensions, application, tests, requirements for a 7-pole connector type 12 N (normal) for vehicles with 12 V nominal supply voltage between a tractor and a trailer.
Note: If the 7-pole electrical connector cannot meet the requirements, the 13-pole electrical connector specified in GB/T 20718 can be used instead of the combination of this standard and the 7-pole electrical connector, which is specified in ISO 3732.
