CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the usb-a 2-way panel socket branch harness form as a starting point and confirm these design points against drawings and the actual equipment.以USB-A双路面板插座分支线束的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Panel-mounted connection面板安装连接
The interface is arranged at a panel or feedthrough, with front/rear clearance, fixing positions and cable exit defined around the enclosure.接口与面板或穿壳位置配合，前后端连接空间、固定孔位和出线方向可围绕机壳定义。
USB connector endUSB连接端
The USB-form end provides a device connection boundary, with end orientation and lead routing arranged for the installation space.USB形式的端头可作为设备接入边界，端头朝向与引线走向按安装空间布置。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Does every Type-C cable support high-speed data and high power?所有 Type-C 电缆都支持高速数据和大功率吗？
No. Type-C identifies the connector system. Data lanes, power duty, Configuration Channel wiring, electronic marking, directionality and equipment capability determine the usable functions.不能。Type-C 只识别接口系统，实际功能取决于数据通道、供电负载、Configuration Channel 接线、电子标记、方向性与双方设备能力。
Does passing continuity prove a high-speed USB cable is good?导通合格能证明高速 USB 电缆性能吗？
No. Continuity proves point-to-point connection. High-speed performance also depends on impedance, loss, crosstalk, termination, length, bending and the complete channel.不能。导通只证明点对点连接，高速性能还取决于阻抗、损耗、串扰、端接、长度、弯曲与完整链路。
Can you build a charging-only cable?可以制作仅供电 USB 线吗？
Yes, when the required identification, CC or other circuits, current, voltage drop, temperature rise and misuse controls are explicitly defined and approved.可以，但必须明确并批准所需识别、CC 或其他回路、电流、压降、温升以及防误用措施。
