GB/T 5053.2-2006Road vehicles - Connectors for the electrical connection of towing and towed vehicles. 7-pole connector type 12 N (normal) for vehicles with 12 V nominal supply voltage (English PDF)

Foreword

This Part is equivalent to ISO 1724:2003 "Road vehicles - Connectors for the electrical

connection of towing and towed vehicles - 7-pole connector type 12 N (normal) for

vehicles with 12 V nominal supply voltage" (English version).

The following editorial changes have been made to this Part:

a) MODIFY the name of the standard;

b) USE "This Part" to replace this "this International Standard";

c) ADD the foreword of Chinese standard;

d) Where there is a national standard that equivalently adopts the international

standard among the cited standards, CHANGE it into the corresponding national

standard;

e) EXPLAIN the selection and numbering of specimens in 6.1;

f) ADD the references.

This Part replaces GB/T 5053.2-1985 "Electrical connections between motor vehicles

and towed vehicles - Type 12N". Compared with GB/T 5053.2-1985, the main

difference between this Part is the addition of tests and requirements (Chapter 6)

This Part was proposed by the Ministry of Communications of the People's Republic of

China.

This part is under the jurisdiction of the Trailer Sub-Technical Committee of the

National Automotive Standardization Technical Committee (SAC/TC 114/SC 13).

Communications, CIMC Vehicles (Group) Co., Ltd., Jiangsu Academy of

Transportation Sciences, Jilin University, Jaeger Baowei Auto Parts (Shenzhen) Co.,

Ltd., Jiangsu Provincial Highway Society.

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.
