Let’s get one thing straight about Connectors. We aren’t here to talk about people that connect other people. We are here to talk about a different kind of connector – that is, electro-mechanical devices that join two or more electrical circuits together. So if you are here to learn about electrical connectors, you are in the right place.


Most of these connections are permanent, but not all. Some are temporary, making the equipment portable. This is nice, because it allows it to be assembled, dis-assembled, and then moved if necessary. Power connector types have nearly endless varieties. They come in different lengths, sizes, shapes, capabilities, and specs. There are even connector accessories.

Features vary according to the need of your application. Differentiating factors include:

  • how rugged they are
  • their size
  • shape
  • how they handle environmental changes
  • ease of connection
  • mating type
  • construction
  • pin insulation
  • durability

No matter what type of connectors you seek, you are bound to find what you need.

Connectors can be confusing. To address this, many connector manufacturers try to draw parallels to the human world. For example, there are male connectors with protruding pins. Female connectors have sockets.

To reduce the risk of incorrect mating (see what I mean about parallels to the human world?), connectors can be “keyed”. This means a mechanical component is added to prevent incorrect mating (or attachment).

Connectors serve a variety of purposes. Terminals connect two or more wires. A terminal block connects singular wires (without splicing them). Regardless, they all serve a basic task – which is to make a connection (just not in the human way).

Well, we hope you’ve enjoyed our brief tutorial on connectors. While the information is (admittedly) basic, it’s a start. For more information on connectors, click here. Come back later, as we’ll be adding more information as the weeks progress.
