Use the dual circular plugs y-branch power branch harness form as a starting point and confirm these design points against drawings and the actual equipment.以双圆形插头Y型电源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。
Circular connection end圆形连接端
The end uses a circular interface form, with connection positions planned around mating direction, retention and cable exit.端头具有圆形接口形式，可围绕对插方向、端部固定和线缆出口规划连接位置。
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。
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。

Custom wire harness manufacturing in China中国工厂 · 定制线束制造
Our China factory supports pigtail & branch harness projects through custom wire harness manufacturing and OEM/ODM development. Interface, circuit and installation data guide material selection, sample builds and manufacturing-document approval before repeat production.Super Smile-Tech 中国工厂围绕尾线与分支线束的项目需求提供定制线束制造与 OEM/ODM 支持。我们从接口、电路与安装资料开始，协同物料选配、样品制作和制造文件确认，再按批准要求组织重复生产。
Develop from branch drawings and pin tables依据分支图与针脚表开发
The drawing defines a main datum, every branch length, connector view, cavity routing, splice position, protection and labels. Dimensions state whether the harness is straight, naturally laid or formed.图纸明确主基准、每条支路长度、接口视图、孔位路径、接点位置、防护和标签，并说明尺寸是在拉直、自然放置还是成型状态下测量。
Reverse an existing pigtail without hidden assumptions依据样品开发但不保留隐藏假设
A sample establishes visible dimensions and interfaces, while circuit function, ratings, internal joints, plating and sealing are verified separately. The result becomes a controlled part rather than an undocumented copy.样品用于确认可见尺寸和接口，回路功能、额定、内部接点、镀层与密封则单独核实，使结果成为受控零件，而不是无记录复制品。
Create serviceable repair branches制作便于维修的替换分支
Damaged ends can be replaced with defined overlap, staggered joints, labels and protective sleeves. The repair position, access space and joint method are planned so the repaired section can be inspected and supported.损坏尾端可通过明确搭接、错位接点、标签和防护套管替换。维修位置、操作空间和接点方式需要提前规划，使修复段可以检查并获得支撑。
PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
What is the difference between a pigtail and a branch harness?尾线和分支线束有什么区别？
A pigtail usually has a connector or terminal system at one end and free or prepared leads at the other. A branch harness divides one or more circuits into two or more controlled tails. Some products combine both structures.尾线通常一端带连接器或端子系统，另一端为开口或已处理引线；分支线束把一个或多个回路分成两条以上受控尾端，有些产品会同时包含两种结构。
What information is needed for a quotation?报价需要提供哪些资料？
Provide connector and mating part numbers, pin table, branch drawing with datums, each tail length, conductor sizes, loads, splice and sealing requirements, environment, quantity and inspections.建议提供连接器与对插件型号、针脚表、带基准的分支图、各尾端长度、导体规格、负载、接点与密封要求、环境、数量和检验项目。
Can you reproduce a pigtail from a sample?可以依据样品复制尾线吗？
Yes, but hidden pin routes, conductor ratings, plating, internal splices and acceptance criteria still require confirmation. A sample is evidence, not a complete specification.可以，但隐藏针脚、导体额定、镀层、内部接点与验收标准仍需确认。样品是开发依据，不是完整规格。

Share mating interfaces, a circuit table, target lengths or a sample for the dual circular plugs y-branch power branch harness. We can use them to review configuration and sample requirements.提供双圆形插头Y型电源分支线束的对插接口、回路表、目标长度或参考样品，我们据此梳理选配与样品确认事项。
