CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the dq250 02e transmission circular main plug pigtail form as a starting point and confirm these design points against drawings and the actual equipment.以DQ250 02E变速箱圆形主插头尾线的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Plug-in connection end插接式端头
The end uses a plug-in form, with clearance arranged for insertion, removal and cable bends.端头采用插接形式，可围绕安装位置安排插入、退出及线缆弯曲空间。
Pigtail connection form尾线连接形式
A lead section extends behind the connector, allowing length, further termination and support to follow the equipment connection.插接端后保留引线段，便于按设备接线位置确定长度、后续端接与支撑。
Trunk and branch layout主干与分支
Locate trunk and branch datums from equipment fixing points. Allow room for mating, bends and servicing so branches do not transfer installation loads to contacts.以设备固定点确定主干和各支路的尺寸基准，预留插拔、弯曲和维护空间，避免支路把拉力传递到端子。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is an external transmission lead the same as an internal mechatronic harness?箱外变速箱引线等同于箱内机电液线束吗？
No. They have different installation, fluid exposure, connector and cleanliness requirements. Define the breakpoints and whether a through-case interface belongs to the assembly.不等同。安装位置、油液暴露、连接器和洁净度要求都可能不同。必须明确断开点，以及穿壳接口是否属于供货范围。
Can a matching gearbox plug prove interchangeability?变速箱插头能对插就能互换吗？
No. Compare transmission and controller references, cavity view, circuit assignment, terminal system, sealing parts and software variant. A mating shell does not validate shifting behavior.不能。还要比较变速箱与控制器料号、孔位视图、回路分配、端子体系、密封件与软件变型。能插上不等于换挡行为正确。
Does continuity testing prove the feedthrough will not leak?导通测试能证明穿壳接口不漏油吗？
No. Continuity tests electrical mapping. Fluid containment needs the correct approved seals and installation, followed by the project-specific leak or pressure test.不能。导通只检查电气映射。油液密封需要正确的批准密封件和安装，并按项目规定进行渗漏或压力试验。
