Learning About Connectors

Let’s face it – learning about connectors isn’t easy. It’s a complicated business, and one that takes time and effort to understand.

Take the sheer variety involved. There are power connectors, d-sub connectors, rectangular connectors, circular, fiber optic, hermetic, and thermocouple. And that’s just for starters!

So where should one begin? One way would be to start with the classic d-sub connector. It doesn’t get a ton of respect in 2014, but let’s look at it’s past for a moment, shall we?

A d-sub connector, of course, is named for it’s d-shaped shell. Years ago, these connectors were used for floppy drives on Macintosh computers. This was also the case for the Commodore Amiga. But due to their size and cost (and the prevalence of smaller, less expensive connectors), the poor d-sub connector has really dropped in popularity. Such is life.

But what is a d-sub connectors? It’s a connector that contains two or more parallel rows of contacts surrounded by the classic D-shaped metal shell. The shell provides mechanical support and guarantees the correct orientation, but it also screens against electromagnetic interference.

So there you go. There’s one example of what you can learn about connectors. But there are many more! Let’s take another example: power connectors.

A power connector is the link between a device and the device’s source of power. It’s as simple as that. Well…no…not really. Let’s move on. These are common in popular consumer electronics, such as T.V.’s. You surely use them yourself, plugging your flat screen into your wall for years worth of enjoyable entertainment. But that’s not the type of power connector we are here to talk about. We’re going to be talking about connectors that are used in non-consumer equipment.

But that’s a conversation for another day. For now, we’re signing out. Tune in later for more information from the Connector Learning Hub.
