A guide to electrical connectors

What are wire connectors? Are there different types of wire connector? How do wire connectors work? Our useful guide tells you everything you need to know about electrical connectors.

What are electrical connectors and terminals?

In electrical work, terminals and connectors, as their names suggest, are used to terminate a wire or cable completely or to connect them to an electrical system.

When to use electrical connectors and terminals

Connectors and terminals are used for new electrical installations and when replacing parts that have become damaged through being bent, cracked, or burnt.

There are several electrical connectors and terminals on the market and at cableties-online, we supply the following:

Closed end connector terminals

A closed end connector requires no solder to seal and terminate stranded wiring. Our closed end connector terminals offer a quick and cost effective way to permanently connect two or more electrical wires. Featuring tin plating for corrosion resistance, our connectors are available in three handy sizes.

Wiring connector strips

We offer strips of terminal blocks that are available from 3 to 60 amps. A terminal block has an insulated frame which secures two or more wires together and is a much safer method than stripping and twisting wires together. Each block has a clamping component plus a conducting strip and will keep connections more secure.

Brass bullet connectors

Bullet connectors offer a great solution for connecting wiring in systems that may need to be moved, such as sound system speakers, and a knowledge of soldering is required when using them. They snap together to make a solid connection but can be disconnected and reconnected easily without compromising the connection. We offer two sizes of brass bullets plus single and double sleeve connectors, which join two and four bullets respectively.

In addition to the above, we also have a range of terminals and low voltage connectors.

Do terminals and connectors need special tools?

When working with any electrical system, the correct tools are essential to avoid malfunction and these include crimping and cutting tools.

Wire and cable cutters

Wire cutters are available in manual and ratchet options. While more expensive, a ratchet tool eases the strain of cable cutting.

Wire and cable strippers

Before using a wire and cable stripper, know the gauge you are working with and the type of cable e.g. flat or round.

Wire strippers/cutters

These are perfect for use with smaller gauge wire and some are available with a tip that doubles as a pair of pliers and also incorporates a crimper.

Your choice of electrical connector will be dependent on what you will be using it for and where. For example, if the connectors will be exposed to the elements, you will need to consider insulated connectors, as extremes of temperature plus moisture may cause damage.
