Each connector has its own way of protecting itself, called strain relief. You can’t just walk up to any connector out in the wild and catch it though. See the notch on the top of this female XLR cable? It only accepts a connection in one orientation. You’ll find this notch or other similar markings on nearly every connector out in the wild. Īn excellent example of polarity is shown in the image below, with this XLR connector, you’ll notice that it has a notch that only allows it to be oriented in one direction. You might also hear this referred to as a connector being keyed. Each one has its own unique polarity, which means that it can only be connected in one orientation with a particular type of connector. Of course, connectors can’t just make contact with any kind of connector. On each connector, there’s a set of metal parts that press together and form a connection. How do these male and female connectors go about mating? Through a process called contact. A USB male (left) and female (right) out in the wild, ready to be connected. These male and female connectors have what are called definite mating cycles, Which means that they can only be connected and disconnected a certain amount of times until they break! For example, USB connectors are designed to be mated thousands of times, whereas something like a Molex power connector can only mate a few times before going belly up. If you’re planning to track and hunt connectors out in the wild, then you’ll need to know how to talk and act like one, so you can blend in! First off, every connector comes in one of two genders, male or female. Let’s see what else we can find out in the wild today! The Lingo Down Under While you might have seen many of these connectors roaming out in the wild in your own electronics, do you know them by name, and what they do? By the end of this blog post you will, but wait, Crikey look, there she is! We finally spotted the mysterious USB-C connector, what a beaut. Welcome, hobbyists, to the wild savanna of PCB connectors! We’ve got USBs, RCAs, barrel connectors, and more all roaming about in the wild, offering ways to transmit power, bring in data as input, and send out new output.
