RS PRO D-Sub Connector with Solder Cups including Stamped and Formed Contacts

From RS PRO a durable D-Subminiature connector with a robust steel shell, stamped and formed contacts and solder cup terminations for the easy connection of wires. These D-sub connectors are ideal for use for making I/O (input/output) interconnections in a wide range of industrial and commercial applications

What is a D-Sub Connector?

A D-Sub connector is a popular type of I/O (input/output) connector that is commonly used in the computer and datacoms industry to provide power and point-to-point communications between two devices such as a computer and a monitor. The d-sub contains two or more parallel rows of pins or sockets surrounded by a D-shaped metal shell which provides mechanical support and ensures the correct orientation is used when mating. These d-subs are available as female D-sub sockets (or d-sub receptacles) with female contacts or male D-sub plugs with male pin contacts. The socket style female connector mates with the plug style male connector. Please note that a D-sub with a plastic shell cannot be mated with a D-sub with a metal shell.

Features and Benefits

• Robust design
• Durable tin plated steel shell
• Dimples on the shell (plugs only) for improved electrical conductivity and grounding
• Good EMI/RFI protection
• Gold plated stamped and formed contacts
• Flanges with for mounting holes for screw mounting to a panel
• Tinned solder cup terminations for simple wire connection

Applications

This d-sub connector with its robust design and high reliability can be used in communications and network ports in a wide range of industrial and commercial applications. Applications include the following:

• Computers, monitors and scanners
• Networking and communications equipment
• Data processing equipment
• Industrial equipment
• Test and measurement instrumentation
• Remote sensors and data loggers
• Portable electric generation equipment

How do you mount these connectors?

These d-subs are designed to be panel mounted. A hole is cut in the panel which is determined by the panel cut-out dimensions of the plug or socket. Two mounting flanges either side of the connector incorporate mounting holes. Holes are drilled into the panel to align with these mounting holes. The connector is then inserted into the panel cut-out and secured in place by inserting screws through the holes in both the connector and panel.

How do you terminate the wires into the connector?

These d-subs feature solder cups which are hollow cup-like cavities into which the wire is inserted and secured by soldering. Firstly make sure the connector is held securely while working on it. Strip the ends of each wire using the depth of solder cups to gauge how much insulation you need to remove. Tin the exposed wire strands with a soldering iron and partially fill the solder cup with solder. Apply a soldering iron to the edge of the cup allowing the solder to melt. Insert the end of the tinned wire into the cup and hold it in place until the solder becomes solid. If the wire gauge is large enough to support itself in the cup place it in the cup and feed in the solder whilst applying the soldering iron to the back of the cup.
