3 Basic Types of Electrical Connectors


In practically all the electrical equipment’s, the connector plays a very important role in determining the performance of the device. But, sometimes, these connectors are also responsible for the failure of a specific product and damages the equipment. Electrical connectors are responsible for connecting the wires to one another and they are also responsible for protecting them. Since, they are responsible for protecting the wires, most of the electrical plug adapter are weather resistant and waterproof, so that they can function in extreme weather conditions also.

Theoretically, connectors should be resistant to factors such as oil, water and pressure, and they should also be relatively easy to connect, while confirming a secure connection when joined with other connectors. Connectors generally play diverse function when incorporated in an electrical circuit. They join the key elements of a PCB to the board, and at the same time bring the signal/power to the system. The most important factor, that determine that if the connector is reliable or not are, speed performance, reliability, ease of assembly etc. Now in this article, we will discuss the three basic types of electrical connectors which are used in most of the electrical or electronic devices we use nowadays.

8P8C Connector

In the 8P8C connector, there is an array of 8 pins, and it generally stands for “8 Positions and 8 Conductor’s”, which means, that for every position of the connector, there is a subsequent conductor for each in the mating socket. Initially, the 8P8C connector, since it is a modular connector was used for telephone jacks, but today, it has its wide application in ethernet jacks.

Now, how does the 8P8C connector works? As we said, it has eight positions with eight conductors. Now, when these conductors get in contact with the other 8 conductors in the socket, the transmit electrical pulses or signals between them. The conductors in the 8P8C connector is the male plug, and hence, it gets aligned with the female conductors in the socket. Before, these connectors were used in telephone lines, but now it is used in ethernet interfacing and also other communication cables.

Most of the modular connectors has names according to their positioning, and the conductors. So, for instance, 9P8C would mean that, the connector has 9 positions and 8 conductors.

D-Subminiature Connectors

The D-Sub or D-Subminiature connector is also a common type of connector, and gets their name from the D shaped face. When the connector was introduced, it was one of the smallest connectors for computers and hence, the name, miniature. The connector generally has two or more rows of pins, which are the male pins, which gets connected to an equal number of female pins in the socket. The connector with the male pins is called the male plug, while the acceptor is called the socket. A successful connection between them enables electricity to flow through.

USB Connectors

USB connectors are a trademark connector in today’s world, and is immensely important in today’s world. From mobile chargers to laptop chargers, from computer accessories to flash drives, everything gets connected through USB today. You can find two or more USB sockets in your laptop or desktop. Some of the variants of USB connectors are USB 1.0, USB 2.0 and USB 3.0. There is also a USB 4.0, which is available in the market now.
