标准摘要
[中文适用范围]: 本国际标准规定了标称电源电压为 12 V 的牵引车(客车或轻型商用车)和被牵引车辆的电气连接的 12 S 型 7 极连接器的尺寸和要求及其触点分配,从而确保互换性。 根据 ISO 1724,在需要 7 个以上极数的情况下,除 12 N 连接器外,还应使用 12 S 连接器。 注:对于新开发以及需要超过 7 极的情况,作为根据本国际标准和 ISO 1724 使用 7 极连接器的替代方案,可能需要使用符合 ISO 11446 的 13 极连接器。 [外文原描述]: ISO 3732:2003 specifies the dimensions of, and requirements for, 7-pole connectors of type 12 S and their contact allocation for the electrical connection of towing (passenger cars or light commercial vehicles) and towed vehicles with 12 V nominal supply voltage, thus ensuring interchangeability. A 12 S connector is intended to be used in addition to a 12 N connector according to ISO 1724 where more than 7 poles are required.
