Termination and shield treatment are inspected before continuity, shorts, polarity, mating, locking, dimensions and project-specific signal or environmental validation.工程在首件前冻结连接器、针脚方向、回路、线缆、尾罩和固定硬件。端接与屏蔽处理完成检查后，再进行导通、短路、极性、插合、锁紧、尺寸以及项目专项信号或环境验证。 |
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。
Serial interfaces and equipment setup串行接口与设备联调
Define serial connections from equipment interfaces and a pin table. Instruments or setup fixtures can then check signal paths and required service access. Identify shell size with standard, high-density or mixed contact layouts.从设备接口和针脚表定义串行连接，再通过仪器或联调工装确认信号路径与所需服务接入点。选配时，壳号与标准、高密度或混合触点排列一起识别。
Multichannel control多通道控制
Record channel numbers, shields and common terminals in the pin table. Define pin/socket gender and solder-cup, crimp or IDC termination.将通道编号、屏蔽和公共端落实到针表。选配时，针式孔式和焊杯、压接、IDC端接分别定义。
Service interfaces and circuit checks服务接口与回路检查
Arrange service-lead length and branches around accessible connections, with a clear pin definition for circuit-by-circuit checks. Match hoods, shielding and jackscrew threads to the panel.检修引线按可接近的连接位置安排长度与分支，并为逐回路检查保留清楚的针脚定义。选配时，尾罩、屏蔽与螺钉螺纹匹配实际面板。
Panel I/O connections面板I/O连接
Define service access from jackscrews, hood and mating-face orientation. Record pin-to-pin and crossover wiring with defined connector views.锁紧螺钉、尾罩与插合面方向共同定义维护入口。选配时，以明确视图记录逐针连接及交叉关系。
Interface replacement for existing equipment既有设备的接口替换评审
For an existing interface, first compare the original connector, mounting dimensions and circuit definition. Similar appearance does not establish mating or wiring compatibility. Identify shell size with standard, high-density or mixed contact layouts.替换旧接口时，先核对原接头、固定尺寸和电路定义；外形接近不能代替对插与接线检查。选配时，壳号与标准、高密度或混合触点排列一起识别。
Multipin numbering and adapter definition多接点编号与转接定义
Use cavity numbering, wire order and the opposite-end function table to define a multipin adapter. Confirm mounting dimensions and service clearance at the same time. Define pin/socket gender and solder-cup, crimp or IDC termination.多接点转接以孔位编号、线序和对端功能表为依据，同时确认连接器的安装尺寸与检修空间。选配时，针式孔式和焊杯、压接、IDC端接分别定义。

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Are DB9 and DE-9 the same connector?DB9 和 DE-9 是同一种接口吗？
DB9 is a common market name for the nine-contact connector, while DE-9 is the more accurate shell designation. Always confirm the mating face, contact sex, hardware and equipment interface rather than relying on the name alone.市场常把九针接口称为 DB9，而 DE-9 是更准确的外壳称呼。应核对插合面、触点性别、固定硬件和设备端接口，不能只依赖名称。
Can D-Sub cables with the same contact count be interchanged?针数相同的 D-Sub 电缆可以互换吗？
No automatic interchangeability exists. Pin map, contact sex, shell, screw hardware, shielding, cable and hidden components can differ even when the contact count is equal.不能直接互换。即使针数相同，针脚、触点性别、外壳、螺钉、屏蔽、线缆和隐藏元件也可能不同。
What is different about high-density D-Sub?高密度 D-Sub 有什么不同？
It places more contacts into a comparable shell size. Cavity pattern, pitch, terminals, wire range and tooling generally differ from standard-density versions.高密度结构在相近壳体尺寸内布置更多触点，其孔位、节距、端子、线径范围与工装通常不同于标准密度版本。
