What Are Mil-Spec Connectors Used for – 2022 Guide

If you are an electrical engineer, you will deal with a lot of different types of equipment. One of those that may come to your hand is the so-called Mil-spec connectors. The word “Mil” actually describes the Military and there is a good reason for that. This tool is developed by the military that had only one goal – to help the army develop different aeronautic applications.

Believe it or not, that invention appeared for the first time 80 years ago. However, over time, it managed to drastically improve and adapt to the requirements that today’s army has. It is now one of the features that all parts of national defense have. For instance, marine is using it all the time as well as people that operate in aerospace. It is also an amazing support for the auto industry. It is perfect support for different types of gas and oil applications.

So, What Is Its Purpose?

The purpose of Mil-spec connectors has different purposes. However, the people that created it did that for only one purpose. They wanted to support the resistance of all the military equipment to different sources of damage. Some of them are high or low temperatures, vibrations, corrosion, and other stuff. In other words, its purpose is to reduce the damage that can potentially occur due to some ungrateful conditions.

How Do They Work?

It doesn’t matter if you are an engineer or not. Understanding how this tool works is not difficult at all. Every connector that you can find comes with a mating pair. One part is actually the receptacle while the second one comes in the form of a plug. Professionals like to say that the female contact (that is also known as the socket) needs to 100% match the male contact (that is known as the pin). After you find the matchable sides, the tool gets plated with other metals. These metals can either be conductive or non-corrosive. A good example of that is gold, silver, and other types of metal with similar characteristics.

What about Fiber Optic Connections?

The phrase “fiber optic connections” is also important and worth mentioning in this article. In cases of this type of connection, the connector that is used for the entire process is often a male plug connector. They have to come with one specific characteristic – protruding ferrule. Thanks to that feature, the fiber will get fixed. If there are two fibers, they will be lined up. Without that, the connection won’t be ensured.

Apart from this feature, there is another one that people should put into consideration. You need to know whether the insertion loss does exist or not. This specification is expressed in decibels and it describes the signal power that has to be lost. Without the loss of light or signal power, the connection won’t manage to be ensured. Because of that, you need to read all the characteristics before purchasing one.

Is It Possible to Purchase Mid-Spec Connectors Online?

We have to be grateful for living in the 21st century. Almost every product or service that you need is present online. The same rule counts when we talk about mid-spec connectors. They are available online in a big number of stores like connectorworld.com.au. However, just because we highlighted one of the best online stores for that type of purpose, that doesn’t mean you should not expand your research.

Generally speaking, you do not have to look for other stores. Instead of that, you should focus on the most important characteristics of any mid-spec connector. That way, you will figure out on your own whether some of them deserve your money and can meet the requirements and expectations that you have. That is the reason why we would want to talk about some other things as well!

Important Features to Put Into Consideration

Electronic engineers will always put into consideration the most important feature of these items. They won’t get impressed by low prices. It is important here to know whether an item of this type can actually help you reach the goal that you have. Here are some of the most important features you should put into consideration.

Characteristics of the Contacts

The buyers primarily need to know how many contacts there are. This number actually shows how many elements there are in the connector that you want to purchase. With this fact, you will figure out on your own how exactly the connection of electricity is made between the contacts. That counts for both, sockets and pins.

Additionally, it is worth mentioning that there are different ways of how these two parts connect. For instance, there is bayonet coupling. This type of connection ensures high jacking capability as well as fast locking. But, not everything around it is perfect, For instance, the rotation is extremely limited which may not be suitable for everyone.

Apart from that, we can also highlight the threaded coupling. This type of connection supports the screw threads that are made on the mating connectors. In the end, there is also the so-called ball detent coupling. In this case, you will get a couple of benefits such as self-locking. Apart from that, this option ensures the reduction of damage in cases where the machines are overloading. Cool feature, isn’t it?

Connectors Shells

For those that do not know, shells are actually the main part of the connector. In 99% of cases, this part of the connector is made of aluminum. That ensures the corrosion-resistance. You can find shells in various styles such as dummy and jam nut receptacle, angled, straight, weld-mount or solder, etc.

And, how long are the connector shells? Well, they can come in different shapes and sizes. In most cases, the minimal size is around 0.5 inches. But, they can go up to 2.25 inches in some cases.

Conclusion

We tried to answer all the relevant questions in this article about mil-spec connectors. You now know what is their purpose, what they can ensure, where to buy them, and which specifications you should put into consideration. After reading this article, you are ready to pick the option that is most suitable for you.
