标准摘要
[中文适用范围]: 本国际标准规定了 24 S 型 7 极连接器的尺寸特性和具体要求及其触点分配,用于标称电源电压为 24 V 的牵引和被牵引车辆的电气连接,从而确保互换性。 根据 ISO 1185,在需要 7 个以上极数的情况下,除 24 N 连接器外,还应使用 24 S 连接器。 注:对于新开发以及需要超过 7 极的情况,作为使用符合本国际标准和 ISO 1185 的 7 极连接器的替代方案,可能需要使用符合 ISO 12098 的 15 极连接器。 [外文原描述]: ISO 3731:2003 specifies the dimensional characteristics of, and specific requirements for, 7-pole connectors of type 24 S and their contact allocation for the electrical connection of towing and towed vehicles with 24 V nominal supply voltage, thus ensuring interchangeability. A 24 S connector is intended to be used in addition to a 24 N connector according to ISO 1185 where more than 7 poles are required.
