3 Basic Types of Electrical Connectors

Any electrical equipment will have different types of electrical connectors within. Each connector comes in different shapes, sizes, and materials. Function is another key factor that classifies the connectors.

From connecting a wire to a board to joining key elements on a PCB, connectors play diverse roles and serve many applications. Despite their simple design, they connect and bring power/signals to the system. Key factors that determine the quality of a good connector is its reliability, signal integrity, speed performance, power rating durability, and ease of assembly.

Connector manufacturers offer an extensive array of tried and tested product solutions.

There a few common connectors which are worth the mention:

8P8C Connector

8P8C connector, where 8P8C stands for “eight positions, eight conductors” have eight positions, with corresponding conductors in the mating socket assigned to each. It is basically a modular connector and was primarily used in telephone wire applications. Today, they serve many applications and functions like being used to interface Ethernet jacks.

The 8P8C connectors have a male plug and a corresponding female socket connection. It carries eight contacts and when they get aligned with the corresponding eight conductors within the sockets, electrical signals get transmitted. Apart from Ethernet and telephone wires, they are also used in computer applications and other communication cables.

Generally, most modular connectors are technically named after the number of positions and conductors. They include sizes like -4-,-6-, 8-, and -10-. For instance, a 10P8C will have ten positions with eight conductors.

D-Subminiature Connectors

D-subminiature is much similar to 8P8C, as they are used in computer and play a critical function on modems. Though the name states “subminiature”, these are larger than most modern computer connectors. The connector has a D-shaped metal component that defines its shape and protects it. It also consists of two or more rows of pins with varying numbers in the male connector and a similar set of receiving ends in the female part. The male connector with a pin is called a plug whereas the receiving part that houses the contacts that connect these pins is called a socket. This connection is established to transmit electrical signals. This variant has the capability to provide protection against electromagnetic interference, commonly known as EMI.

USB Connectors

USB or Universal Serial Bus is a very common type of connector. They are small interfaces used to attach multiple devices to a computer. You can see at least two USB ports in any standard laptop that support external USB connectors and cables, while desktops have up to 4 USB ports in general. USB connectors gained much popularity and recognition, as it can be connected and disconnected easily while the device is still working. This contributed to its widespread use in computer applications that constantly require plugging and unplugging external devices, especially for transferring data.

Simple, Yet Effective Techniques To Reduce Transformer Noise

A transformer is an electronic device made of stainless steel windings and cores and performs the function of supplying power from one source to another through electromagnetic induction. The device is very useful in commercial as well as industrial sectors and more and more people switch to the technology for better power supply. Though, the device in some cases creates a lot of noise that can be harmful to the users and the device itself. Therefore, it is important to take some serious actions to get rid of the transformer noise, but before you hit the head and looking for a way, it is important for you to understand what the main cause behind such noise is. Identifying the main cause helps you solve the problem more efficiently and effectively. So, what are you waiting for? Just scroll down to get the answer to your query.

Basically, There Are Two Major Causes Of The Transformer Noise Such As:

  • Magnetostriction: It is basically a property of ferromagnetic materials that leads them to extract or contract their shape or dimension during the magnetization, which may create vibration in the device that automatically leads to transformer noise. You can simply control the Magnetostriction by the transformer design, so, you have to be very particular while making the choice of its type, model, and size.
  • Mechanical Abrasion: Another major reason of transformer noise is Mechanical Abrasion. Any sort of force and stress on the device creates vibration. Any vibration comes from the core is transferred to anything else attached to it that may cause the transformer noise.

Simple Techniques To Fix The Issue:

  • Reducing flux density can be very helpful in eliminating the transformer noise. Though, it is an expensive method because for reducing flux density you have to increase the amount of stainless steel in the core that requires investment.
  • Don’t worry, if your budget doesn’t allow you to pick the above technique, so you can go for another option that is the use of suitable adhesive to minimize the vibration that automatically reduces transformer noise. Putting adhesive between lamination layers is not so expensive and delivers you the effective and expected results. But you have to be sure that sheets are free from any contamination and also don’t have any oil scum.

These simple tricks and techniques help you get rid of transformer noise and all of are very easy to adopt. But make sure you consult an expert before picking any of the techniques as the method can be varied as per the model of your device.
