How To Choose The Right Wire Connector
These are just some of the primary things that are to be considered among many others. It is impossible to outline the perfect connectors for wires in a particular situation without a thorough assessment of various factors.
However, the buying factors dictated in this article are generic and thus become viable in almost all situations.
1. Water Resistance
The right connectors for your wires will always be the one that is covering all of your needs for a specific task. There are no "absolute best" when it comes to wire connectors. It all depends on what you are going to use this wire connector for and whether its attributes correspond to your requirements.
For example, you might want to run a connection that will be submerged underwater. For this, you will want a connector that is water-resistant and is built to withstand the pressure of varying depths of water.
2. Smooth Connection
Let’s say you are in an area where there is constant electromagnetic interference and you want to set up a wired connection without the interference affecting it.
To successfully achieve this, you will want your wire connectors to have special features built-in that can negate and divert these interferences to assure a smooth running connection.
It is necessary to assess and illustrate the application that is going to run a wired connection and its requirements before making a decision.
Some of the things that should be considered are the voltages and current that is going to pass through the wire. If there is a considerably large current path, then we would suggest you get a connector that can house a wire that is bigger and thicker and features an appropriate current rating.
4. Proper Insulation
Another thing to consider is the environment that the wire connectors will be planted on. If the connector is required to work in a hot environment then appropriate insulation is a must-have to prevent any damage.
Similarly, other hazardous invasions such as toxic gas and combustible vapors or liquids can be prevented if the wire connector is built with protection against these ailments.

Benefits of Using Wire Connectors
Time Management and Ease of Use
We cannot stress this fact enough. You don't want to take up hours daily just to work on wiring up one sconce in your house. It all adds up when you are working on multiple projects regularly.
Over time the wiring process will get hectic and tiresome, not to mention that it will be extremely time-consuming. On the other hand, you can use wire connectors to quickly hook up a set of wires and get them functioning in mere minutes.
This becomes especially handy if you are an individual with a lot of DIY projects or someone who is working with small appliances.
This is because these smaller jobs frequently require much smaller wires and intricate connections which can be extremely difficult to get right manually, but that all changes with a connector.
Another important management aspect is the tidiness of the wires you are working with.
You don't want to get jumbled up with wires especially if it's a project that requires a lot of connections. Not only does it create a mess, but it can also be potentially dangerous in the event of a short circuit or a connection malfunctioning.
You can neatly tuck connected wires away from sight, shielding it from any hazardous environment and making the appliance look better. After all, you don’t want pesky wires sticking out from your beautiful garden lights.
Perhaps the most important benefit of using a connector for wire is the safety factor. And this safety factor goes both ways because it applies to both the appliance that you are working with and yourself.
Wire connectors can be used to string together wires in a hazardous area so they can be tucked away from potential threats that they may otherwise be exposed to – shielding them.
If a strong electric current flows through the wires, then a robust connector will do a good job at keeping the connection steadfast and secure.
Moreover, if there are multiple wires packed together in a small circuit box, then these wire connectors will form a barrier. This prevents one wire from making contact with another, resulting in dangerous short circuits and multiple failures.
Types of The Wire Connectors on The Market
There are hundreds of different types of the top quality wire connectors that are used all over the world, and more specialized types are being created over time.
It is impossible to list every single one, however, we will give you the rundown of the most common and the most important types of wire connectors that you will be using in your everyday projects.
1. Butt Splice Connector
One of the most common and widely used connectors, the butt connector is a cylindrical crimp connector with two ends that are used to create a straight splice.
2. C-Tap Compression Connector
These connectors are shaped like a “C” so that it is viable for two way splicing. They compress around their respective ends so that when a wire is joined in, a closed bond is formed, strengthening the joints. Electrical pig tailing requires C tap connectors and is its most desired functionality.
3. Closed-End Crimp Connector
The closed-end crimp connectors act like a seal. They are primarily used to close off stranded bits of wire, terminating their connection and rendering them dormant.
4. Spade Connector
Also known as fork wire terminals, this type of connector is mainly used in plug-and-play scenarios. They allow users to instantly connect or disconnect a running connection in electric boards and screw-type connections. Stereos and DVD players are the finest examples for objects that use this connector.
5. Lug Compression Connector
Similar to the spade connectors, the Lug Compression Connector houses the ends of wire inside them and then attach themselves to a circuit board or a metal conductor. This is designed to physically pass your connection from the wire directly to the circuit without the use of another medium.
6. Pin Type Connector
Pin type connectors link with wires and connect them to terminal blocks. Different variations of pin type connectors exist and it is possible to customize them greatly for specific wire terminals.
7. Split Bolt Connector
The vintage connector used in the past. The split bolt connector targets a set of specific metal wire ends and rigidly hold them together using a bolt and a screw. The metal wires are usually of aluminum or copper origin, although variations can exist.
8. T-Type Connector
A connector designed to have the shape of the letter “T”. It is very similar to C tap connectors. The difference is, it connects the ends of three different wire in a “T” shaped arrangement.
9. Lever Connector
The poster boy of wire connectors. Lever connectors are the most widely used connector in every industry. It is also one of the simplest and beginner-friendly connectors.
It consists of a lever that has to be pulled down before sliding in a wire, after the wire has been placed, the lever is pulled down, ready to form a connection through the other end. Different variations of the lever connector exist such as two or three-way lever connectors.
10. Snap Lock Connector
The snap-lock connector allows connections without cutting or splicing wires beforehand. It consists of a latch that has a blade built inside it. This blade is used to splice the wires in the exact orientation of that specific snap-lock connector.
To use it, simply open the latch, stick the wires in together and close the latch and you are ready to go.
Frequently Asked Questions
Q1. What Is Crimping And Is It Necessary For Every Wire Connector That I Use?
Answer: Crimping is physically deforming the conductive metals inside the wire in specific orientations so that they can be joined together with other crimped wires. Crimping is necessary for every wire connector as it is the most important part of creating a joint between these wires.
Crimping is usually done with special tools such as a crimping plier but some connectors have built-in crimpers in them such as the snap-lock connector.
