D-sub Connectors

A D-subminiature connector, also known as a D-sub, is a ubiquitous connector type named for its distinctive D-shaped metal shell. It is used in a broad variety of applications from consumer products to satellite equipment.

D-sub Connectors Defined

D-Sub. D-Sub连接器包含由特征D形金属壳包围的两个或多个平行行。壳牌不仅提供机械支持并确保正确的方向,而且还可以筛选电磁干扰(EMI)。ManBeTX2018万博官网使用几种方法将系统电路连接到D-Sub连接器中的触点,包括压接,焊接杯,PCB焊料,PCB压配合和钢丝包装连接。许多次锁定系统被实施以确保连接器remain in a mated state despite shock and vibration conditions.

D-Sub连接器有时会与Micro-D系列和SCSI附件系列混淆(以HD-50和HD-68这样的连接器为特色)。这些产品与D-Sub连接器分开且不同。D-DIM有时被称为“矩形机架和面板”连接器,并且通常携带诸如DB9,DB15,DB25,DB37和DB50的白话引用,其中数字是指连接器的PIN计数。

USES

D-Sub连接器使用各种电子设备。它们通常在通信端口上找到,创建不同产品之间的连接,如计算机,打印机和电源单元。DB9连接器用于令牌环网以及其他计算机网络和控制器区域网络(CAN)。D-Sub连接器还用于计算机视频输出,游戏控制器端口,多通道模拟和录音工作室中的AES数字音频。

Over the years, the connectors’ use has varied with the technology available at the time. For example, early Macintosh computers used them to connect to external floppy disks, and theCommodore Amigaused a D-sub for external floppy disks as well as video output. But due to their size and cost, D-sub connector use in consumer products has all but disappeared. However, they are still popular in non-consumer applications where its form factor, size, density and cost combination offer significant value to the end user.

PRODUCTS

Positronic carries a wide variety of D-sub connector families andD-sub accessories。标准和高密度D-MixInIture系列高度可靠,具有六种封装尺寸和多种性能选项,以获得性能比的最佳成本。所有正极D型液都采用固体,机加工触点,以确保可靠性,耐用性和强度。

Combo-D连接器是D-Sub连接器的子类别,其特征在于混合密度绝缘体,其组合尺寸8和尺寸20或22触点,允许信号,电源,光纤,同轴器和/或单个封装中的高压触点。理想的是作为输入/输出连接器接口,这些连接器具有许多封装尺寸和接触式变体以及各种配件和选项,包括盲交配和顺序配合。

Or if you’re looking for something a bit more cosmic, try the high performance D-sub connector, which is designed for use in space flight. Available with a lightweight aluminum hood for protection and low magnetic characteristics, many of these connectors are qualified to the NASA GSFC S-311 specification.
