Jumper Harness跳线线束
JST-SM 3-Core HarnessJST-SM三芯连接线束
JST-SM 3-Core Harness can be configured around equipment interfaces and routing. Jumper harnesses are short interconnects used between boards, modules, terminal points or adjacent devices. Their simple appearance can hide different pin routes, orientation and current requirements.JST-SM三芯连接线束可围绕设备接口与安装路径进行配置。跳线线束通常用于电路板、模块、端子点或相邻设备之间的短距离连接。外观虽然简单，但针脚路径、方向和电流要求可能完全不同。

Custom wire harness manufacturing in China中国工厂 · 定制线束制造
Our China factory supports jumper 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 中国工厂围绕跳线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。
Build from a pin-to-pin table依据针脚对应表制作
The approved table records cavity numbers, wire colours, conductor sizes, circuit names, shields, polarity and any crossed route. The harness drawing adds length datums, connector views, labels and inspection points.批准的针脚表记录孔位、线色、导体规格、回路名称、屏蔽、极性与交叉路径；线束图纸再补充长度基准、接口视图、标签和检验点。
Develop from samples without guessing依据样品开发但不猜测
A reference jumper helps confirm dimensions, connector orientation and visible materials. Hidden pin routes, ratings, plating, internal splices and acceptance requirements are verified separately before the sample is copied.参考样品可以帮助确认尺寸、接口方向与可见材料，但隐藏针脚路径、额定、镀层、内部接点和验收要求，需要单独核实后再复制。
Convert between different interfaces不同接口之间转接
When two modules use different connector families, the jumper is designed as a controlled adapter. Pin function, signal pairing, grounding, shield continuity, voltage and current compatibility are reviewed before defining the mechanical conversion.两个模块采用不同连接器系列时，跳线应作为受控转接件开发。先审核针脚功能、信号配对、接地、屏蔽连续性、电压与电流兼容，再定义机械转接。
PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is a jumper harness always wired straight through?跳线线束一定是直通的吗？
No. A jumper can be straight-through, crossed, reversed, split or combined with shields and specified components. The approved pin-to-pin table is the production and test reference.不一定。跳线可以直通、交叉、反向、分支，也可能包含屏蔽或指定元件。批准的针脚对应表才是生产与测试依据。
What information is needed for a quotation?报价需要提供哪些资料？
Provide both connector and mating part numbers, a pin table, circuit function, voltage and current, length datum, wire and colour requirements, environment, quantity and inspection requirements. Photos or samples can supplement missing drawings.建议提供两端连接器及对插件型号、针脚表、回路功能、电压与电流、长度基准、线材与颜色要求、环境、数量和检验要求。照片或样品可以补充不完整的图纸。
Can a jumper be developed from an existing sample?可以依据现有样品开发跳线吗？
Yes, but a sample cannot reveal every rating or hidden circuit reliably. Pin mapping, conductor specification, terminal system, plating, polarity and acceptance criteria still need confirmation before repeat production.可以，但样品不能可靠展示全部额定或隐藏回路。重复生产前仍需确认针脚、导体规格、端子系统、镀层、极性与验收标准。
