CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the usb-a to 2-way screw-mount socket harness form as a starting point and confirm these design points against drawings and the actual equipment.以USB-A转双路螺丝安装插座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。
End transition layout端头转接与组合
The assembly organizes a transition or combined connection, with end directions, transition sections and fixing arranged around the equipment positions.组件以转接或组合形式组织连接，可围绕两端设备位置安排端头方向、过渡段与固定。
Signal path信号路径
Define signal type, pair allocation, shield continuity and termination as well as the connector shape. Establish transmission performance from the actual cable, length and system validation.在接口外形之外确认信号类型、线对分配、屏蔽连续性和端接方法；传输能力应按实际线材、长度及整机验证结果确定。

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。
