Connectors are used where wires lines need to be connected and disconnected. Using a connector provides a huge amount of flexibility. Electronic circuit boards, i.e. printed circuit boards can be assembled and tested. When they are complete they can be quickly connected into the final unit or system.
Although the basic concept of connectors is relatively straightforward, there are some features about connectors that are useful to define before moving on.
- Gender: Connectors are referred to as being male and female types. The female connector is generally a receptacle that receives and holds the "male" connector. The male connector has the pins that enter the female side of the connector.
- Orientation: It is essential that connectors are plugged together with the correct orientation. Although some two pin connectors may be able to be plugged in either way, in most instances ensuring the correct contacts mate is essential to make sure the right connections are made.
- Strain relief: One of the issues with connectors that have cables or wires entering them is that the connections to the pins can be fragile. If the cable is pulled or the connections are strained in any way the connections of the wire to the connector can break. To help overcome this, the cable entering the connector can be clamped so that once inside the connector there is no movement and the joints between the cable and the connector contacts remain intact through the life of the connector, thereby considerably improving the reliability.
Connector circuit symbols
Connectors are represented within schematic circuit diagrams in a number of ways. Normally the symbols are quite obvious, but dependent upon the actual system used, the notations used for the connector circuit symbols may vary slightly.

Key connector topics
Connector technology has developed a long way and as a result there are numerous connector topics that are of importance.
- Connector types: Connectors are used in huge number of different areas where they have a large variety of different requirements. As a result there are many different types on connector: circular, straight, those for PCBs, RF connectors and many more.
As might be expected there are many series of popular connector formats that are used in vast quantities. Connectors like jack or phone connectors, IDS connectors, XLR connectors, D-type and many more.Read more about . . . . Connector Types.
- Connector specifications: When selecting a connector it is very useful to be able to understand the various specifications and how they affect performance. In any connector datasheet there is a lot of different parameters quoted. Understanding which ones are important and how they affect the performance of the particular circuit or application is key to selecting the right connector.
