For the purpose of this article, we will focus only on connectors that are used in residential and small commercial projects and as part of craft works. If you are an enthusiastic handyman, you will need to use quality electrical connectors to bring your projects to life.

However, we&#;d like to mention that if you are not a trained electrician, we strongly advise against complex electrical installations on your own.

What Are Electrical Connectors? 

Electrical connectors serve a specific purpose in an electrical application. They create an electrical connection between two components, enabling the electrical signal to pass. Additionally, connectors also need to protect the signal to ensure a safe and reliable transfer between the components.

Electrical connectors such as butt connectors can connect different parts of the same circuit together, but they can also build a connection without different circuits and even different electrical networks.

At Wirefy, we are committed to providing high-quality wire connectors that can function in both simple and complex electrical setups. We supply connectors to applications in industrial settings such as RC, automotive and marine, but also in residential projects.

Electrical Connectors - Basic Composition

There are two main components to an electrical connector, namely the housing part and the terminal block. 

Terminal blocks refer to the part of the electrical connectors equipped to carry the electric current. This part is made out of a conducting material, typically metal. 

The housing is the part of the connector you can touch without risking an electrical shock. It is made of insulating material and designed not to conduct any current. The housing is typically the visible part of the electrical connector and is designed to be sturdy and stable to protect the connection. 

Electrical Connectors - Types

Electrical wire connectors can come in a variety of shapes. The shape of connectors allows for easy connection and is designed to reduce the strain of current transfer. 

At Wirefy, our terminal blocks are available in the following shapes:

Electrical Connectors - Gender

Electrical connectors are labeled either male or female as a reference to their shape and function.

For clarity, male electrical connectors are generally plug or pin connectors. Female connectors, on the other hand, are receptacle connectors that allow the connection of a separate male connector. The plug or pin part is inserted into the female ends to form a coupling. Each connector is attached to a wire or an application with a conductive terminal.

At Wirefy, all our electrical connectors are designed for long-term or permanent coupling, making them an ideal solution for marine heat shrink connectors.

Essential Consideration for Electrical Connectors

When it comes to choosing the right electrical connectors for your projects, you want to consider the pressure and environment relevant to your electrical installation.

Choosing the right connectors is crucial to effectively connect wires and ensure a reliable electrical system.

Environmental Protection

Depending on your electrical project, the connection may require additional environmental protection from external factors. For example, harsh environments can expose connectors to extreme weather. So, it is important to look for electrical connectors that can create the type of seal you need for your circuit. 

Whether you are looking for weatherproof, waterproof, or UV resilient, these considerations will influence the choice of your connectors. Typically, heat shrink wire connectors and heat shrink connector kits are preferred for their environmental protection features, keeping rain, wind, and more at bay. 

Durability

Electrical connectors must be resistant. If they are part of a permanent circuit, they need to be able to remain in place even when exposed to some tugging, stretching, or any other external pressure. 

Here again, the focus is on working with electrical connectors that can guarantee a tight and secure connection designed for long-term usage. This is where heat shrink connectors can elevate your installation. 

Ease of Installation

Essentially, electrical connectors need to be easy to use. The last thing you need during an electrical project is to waste precious time and effort establishing a connection between two different electrical parts. You want to be able to set up a quick connection without needing cable ties to hold your installation. 

Electrical Connectors - AWG

To cater to a variety of electrical projects, electrical connectors need to match your requirements.

It is important to ensure the appropriate current rating, the size of your wire will help determine the amperage to expect. As a rule of thumb, the wire with a high diameter will carry more power. The size of your wire is determined by the AWG (American Wire Gauge), and the smaller the AWG the larger the wire. 

When looking for the right connector size, it is important to consider that the AWG doesn&#;t include the size of any insulating layer protecting the wire. 

Using the Right Tools: Crimping or Soldering?

Lastly, installing electrical connectors requires the use of specialist tools. As explained, for durable and resilient installation, the priority is to select electrical connectors that are easy to set up and solid. 

For this purpose, we recommend choosing electrical connectors that can be installed using crimping. This process will guarantee long-term use and solidity, holding both parts of the connection in place. Make sure to select heat crimping tools that are suitable for a heat shrink connector. 

Unlike soldering, which can be time-demanding and still expose the electrical circuit, crimping adds a protective layer for the electrical connectors without affecting their functions.

Using compatible and high-quality connectors will ensure reliable and safe electrical connections.
What are the benefits of using heat shrink connectors over traditional connectors?

Heat shrink connectors offer several advantages over traditional connectors. They provide a secure and durable connection by combining crimping with heat shrink tubing, which insulates and protects the connection from moisture, dust, and mechanical strain. This added protection enhances the longevity and reliability of the connection, making heat shrink connectors ideal for applications in harsh environments, such as automotive, marine, and outdoor electrical projects.

The Ultimate Guide to Electrical Connectors and Wiring ...

Electrical connectors are indispensable in any wiring project. These humble components ensure that electrical wire is securely joined, allowing the uninterrupted flow of electricity. From wire nuts to DC connectors, understanding your options is important for any electrician or DIY enthusiast.

Types of Connectors

Wire Connector

Wire connectors come in various types, such as wire nuts, Wago connectors, and crimp connectors. Wire nuts are simple but effective, sometimes used to splice together small AWG (American Wire Gauge) wires. The twist and insulating properties of wire nuts make them popular in residential wiring projects.

Crimp Connectors

Crimping involves placing a metal conductor inside a crimp and using a crimping tool to deform the crimp, enclosing and pressing together the conductor securely. Crimped connections are durable and reliable when done correctly. Crimping is often used for electrical wire splicing and terminal applications.

Solder Connectors

In solder connectors, the conductor is soldered to ensure a robust electrical connection. While soldering requires a soldering iron and solder, the resulting connection is extremely stable and strong. These are common in PCB (Printed Circuit Board) and other high-stake electrical wiring.

Other Types

Wago connectors provide a lever-action to clamp down on the wire. They are often used for stranded wire and offer a reusable solution. DC connectors are used in low-voltage applications and are color-coded for positive (RED) terminal and negative (BLACK) terminal to prevent mistakes.

Key Considerations

Insulation

Insulation is another crucial factor. The insulation around the wire should be stripped using a wire stripper to expose the conductor before using any connector. Insulated connectors provide an extra layer of safety.

Wire Gauge

The gauge wire chosen should match the requirements of the circuit and the connector. Using a wire gauge that's inappropriate can lead to overheating or inefficiency. Can sometimes lead to intermittent connection.

The American Wire Gauge (AWG) is a standard system used primarily in the United States to denote the diameter of electrically conducting wire. The current capacity of a wire varies depending on several factors, such as the insulation type, ambient temperature, and whether the wire is in free air or bundled with other wires.

This table provides a rough estimate of the current-carrying capacity of copper wires with different AWG sizes, typically used for chassis wiring.

| AWG Size | Diameter (mm) | Current (Amps) for Chassis Wiring | | :=== | :=== | :=== | | | 11.684 | 302 | | 000 | 10.405 | 239 | | 00 | 9.266 | 190 | | 0 | 8.252 | 150 | | 1 | 7.348 | 119 | | 2 | 6.544 | 94 | | 3 | 5.827 | 75 | | 4 | 5.189 | 60 | | 5 | 4.621 | 47 | | 6 | 4.115 | 37 | | 7 | 3.665 | 30 | | 8 | 3.264 | 24 | | 9 | 2.906 | 19 | | 10 | 2.588 | 15 | | 11 | 2.304 | 12 | | 12 | 2.053 | 9.3 | | 13 | 1.828 | 7.4 | | 14 | 1.628 | 5.9 | | 15 | 1.450 | 4.7 | | 16 | 1.291 | 3.7 | | 17 | 1.150 | 2.9 | | 18 | 1.024 | 2.3 |

Conductor Material
