Circular Connectors Demystified: Understanding the Basics of Design and Functionality


Ever wonder what circular connectors are and what they are used for? What are the common types of these connectors? If you struggle to choose a good connector, you have landed on the right site. We have gathered all the information you need to know about circular connectors. From basic design to functionality, this guide covers it all. Stay tuned and keep reading to find out!

What Are Circular Connectors?

Circular connectors are cylindrical electrical devices with various sizes and multiple circular mating surfaces. Numerous pins attached to connectors that connect with applicable parts to transfer signals, electric power, and even data. You may also know them by circular interconnects. Internal contacts are mated with wires or cables to carry out signals and data.

It's rugged structure and vibration resistance are the most fascinating things. But why is that? A rugged structure and good resistance will eventually save it from impact, temperature, and extreme pressure damage. It will also make connectors catch outside signals, interference, and incursion from gases or dust.

An array of circular connectors is currently available in various materials, including metal, plastic, and composite. You can also choose from a vast range of connector types, including Hermetic, Push-Pull, Mixed Signal, Keyed, DIN, Metric, Micro, and Nano. A hybrid type can be an excellent option because it combines power, signal, and data into a single device. If you wish to tailor a connector product to a particular application, you should get a modular or custom solution.

What Are The Characteristics Of Circular Connectors?

Circular connectors have a cylinder shape that provides a higher strength-to-weight ratio than any other shape. It also allows the resistance to accidental coupling, outside elements, and impact damage. More strength means more resilience. However, it frequently requires mating cycles. Similarly, the number of internal pins in a circular connector varies throughout the application.

The contract layouts and internal keys are assured through proper alignment and insertion into a mating device. Usually, connectors are connected to threaded areas on the shells, but not always. The main purpose of forming this screw-in connection is to allow them to lock securely and freely into position. It remains intact despite the vibrations and impact due to its robust structure.

How Are Circular Connectors Designed?

Let's demystify the complex structure of a circular connectors.

1. Contracts

Contracts are the basic material that holds the connectors in place. It includes pins and sockets housed internally to form an electrical connection through mating. A pair of contracts in each cylindrical connector consists of a male contract pin and a female socket.

2. Insulators

Insulators are used to insulate the material that is encapsulated in the contracts. It insulates them from each other alongside a connector shell. It holds the contracts in the right place and properly distorts them from each other.

3. Shell

The shell is the outer cover of the connector. It's a house for insulators and contracts. When mating the connector halves, a shell provides a secure connector section to each other.

4. Accessories 

Additional parts are essentially used to position, clamp, secure, guide, and seal the various parts of a connector. Accessories include pins, rings, keys, clamps, gaskets, and more.

How To Select a Good Connector?

When choosing a good connector, you need to be very considerate. You must look for a good connector with high-speed digital surveillance equipment. The circuit performance and speed should also ensure high signal integrity. However, there are a lot of factors that you should keep in mind when it comes to choosing a connector, which are listed below.

● Consider the number of wires you are connecting with your device and connector.

● What type of wire are you using?

● What kind of receptacle will be required in the connector?

● What type of back shell is essential?

● Is the connector easily serviced or field-attachable?
