CONFIGURATION结构与选配
Construction & customization options结构与定制配置
The table describes the construction and available configuration choices. Materials, dimensions, circuits and inspection requirements are agreed for each project.以下说明展示结构与可配置内容。具体材料、尺寸、电路和检验要求按项目确认。
| Full JST series, housing and terminal part numbersJST完整系列、壳体与端子料号 | Retain the full series, housing and contact combination rather than a pitch nickname.保留完整系列、壳体与端子组合，避免仅用间距俗称。 |
|---|---|
| Measured pitch, rows and mating direction实际间距、针排与插合方向 | Verify pitch, row count and mating direction from drawings.以图纸尺寸核对节距、排数与插合方向。 |
| Wire size, strip length and crimp-height evidence线径、剥皮与压接高度依据 | Both conductor size and insulation diameter must fit the contact processing range.细线导体与绝缘外径均须落入端子加工范围。 |

APPLICATIONS连接的应用
Application directions应用方向
These are connection directions for project discussion. Suitability depends on interfaces, circuits, installation conditions and project validation; configuration can be adapted to the equipment.以下为可讨论的连接方向。实际适用性取决于接口、电路、安装环境和项目验证，可按设备需求调整。
Equipment control-board connections设备控制板连接
Document pin-row views, mating direction and nearby wire support. Check access to the latch and contacts after assembly. Retain the full series, housing and contact combination rather than a pitch nickname.板端连接要给出针排视图、插合方向和近端线缆支撑；检查装配后是否仍能操作锁扣并查看接点。选配时，保留完整系列、壳体与端子组合，避免仅用间距俗称。
Leads for small electronic modules小型电子模块的引线
Define contact mapping, fine-wire processing limits and enclosure clearance for compact modules. Locate support close to the cable ends. Verify pitch, row count and mating direction from drawings.小型模块的接口定义需要覆盖针位、细线加工范围和壳内空间，靠近端头的支撑位置尤其重要。选配时，以图纸尺寸核对节距、排数与插合方向。
Contact and fine-wire termination端子与细线端接
Contact selection depends on conductor construction, insulation diameter and tooling limits. Set wire preparation and crimp inspection for the actual contact part. Both conductor size and insulation diameter must fit the contact processing range.端子选择同时取决于导体结构、绝缘外径和工具范围；备线尺寸与压接检查应落到实际接点型号。选配时，细线导体与绝缘外径均须落入端子加工范围。
Display-module and control-board connections显示模块与控制板连接
Check insertion direction, contact orientation and frame clearance at display modules. Mark fixed folds on the assembly drawing. Use the actual header or mating lead to check locking and mating space.显示模块连接需核对插入方向、触点朝向与边框空间，并将固定折弯的位置标入装配图。选配时，用实际板端或线端对插件确认锁止和插接空间。
External interfaces on portable equipment便携设备的外部接口
Consider handling, plug grip and cable bends together. Align the exit direction with the device position during use. Retain the full series, housing and contact combination rather than a pitch nickname.便携设备连接要同时考虑操作手势、插头握持和尾部弯曲空间，线缆出口方向应与实际使用姿态协调。选配时，保留完整系列、壳体与端子组合，避免仅用间距俗称。
Module wiring within enclosures机箱内部的模块配线
Coordinate board positions, module removal and wire bends within the enclosure. Preserve insulation clearance and support behind each termination. Verify pitch, row count and mating direction from drawings.机箱内部配线需要协调板卡位置、模块拆装和导线转弯空间；端接后的绝缘与支撑不能被外壳挤压。选配时，以图纸尺寸核对节距、排数与插合方向。
