A splice connector consists of a plastic clip that has a sharp metal insert that will safely cut through the plastic insulating jackets of two wires and crimps them together. Splice Connectors are used to make quick splices or connections with two or more pieces of wire. These splices are normally crimped or soldered so that the power conducted from the source cable to the next cable is transferred at inacceptable conductivity and pull-out resistance performance level.

## **How Splice Connectors Work**

Splice connectors, including common types like butt connectors and barrel crimp connectors, provide a simple and efficient way to join wires. They typically feature a conductive metal insert or blade housed within an insulated plastic body.

To connect wires, they are stripped and inserted into the connector's openings. In the case of barrel crimp connectors, the metal barrel is then crimped using a specialised tool. Butt connectors, on the other hand, often have a seamless metal sleeve that is crimped over the joined wires, creating a compact and reliable connection.

## **Types of Splice Connectors**

### **Crimp Butt Splice Terminal**

Crimp butt splice terminals are tube-shaped connectors with two crimps for joining wires in-line. Crimp butt splice terminals can be used to either change, lengthen or repair conductors in an electrical circuit.

Crimp butt splice terminals are attached by inserting the stripped ends of two stranded wires into both ends of the terminal. A crimping tool is then used to crimp both ends to ensure a tight connection between the wires.

Crimp closed-end connectors are used to terminate wires as well as seal them from oxygen and moisture, which would otherwise cause corrosion.

### **Crimp Closed End Terminal**

Similar to a butt splice, a crimp closed-end terminal features one closed end, making it ideal for [terminating a wire](https://nz.rs-online.com/web/content/discovery/ideas-and-advice/comprehensive-guide-to-ferrules-types-applications-and-more) onto a stud or post. They are favoured for providing excellent strain relief and preventing wires from fraying or pulling out of the connection.

### **Crimp Barrel Foil Terminal**

A crimp barrel foil terminal incorporates a barrel-shaped crimp with an internal foil lining. This foil conforms to the wire shape, ensuring maximum contact and conductivity. This type of connector is particularly suitable for demanding applications where vibration and environmental factors are concerns, as it creates a highly reliable and gas-tight connection.

### **Push Wire Terminal**

Push wire terminals stand out for their convenience, allowing for quick and tool-free wire insertion, often with a spring-loaded mechanism to secure the wire in place. They are a time-saving option, perfect for applications that require frequent wire changes or maintenance.

## **Benefits of Using Wire Splice Connectors**

Wire splice connectors offer numerous advantages, making them an essential tool for various electrical applications:

- **Quick and Easy Splicing: **Wire splice connectors simplify the process of connecting wires, eliminating the need for soldering or complex techniques.
- **Protection from Environmental Factors:** Providing insulation and a secure barrier to safeguard a connection from moisture, dust, and other contaminants is another essential role of wire splice connectors.
- **Reliable Performance:** Wire splice connectors also create strong and consistent electrical connections, minimising the risk of voltage drops or signal loss.**

## **Applications of Butt Connectors**

Butt connectors, known for their versatility and ease of use, find applications in a wide range of electrical projects:

- **Electrical repairs:** When a wire is damaged or needs to be replaced, butt connectors offer a quick and reliable way to mend the break and restore the electrical connection.
- **Extending wire lengths:** If you need to lengthen a wire, butt connectors provide a secure and seamless way to join two wires together.
- **Terminating wires in electronics:** In various electronic devices and circuits, butt connectors can be used to neatly and efficiently connect wires to terminals, ensuring a solid electrical contact.
- **Automotive and industrial applications:** Due to their robust construction and ability to handle higher currents, butt connectors are commonly employed in automotive wiring harnesses and various industrial settings where vibration and harsh conditions are prevalent.
