    What is the difference between a terminal and a splice?

    • Splices are used to typically join two conductor ends together without a mechanical connection. Wire splices feature a metal insert which cuts into the plastic insulation of the wires and crimps them. Wire splicing using a s splice connector means you do not need to solder the joint.
    • Terminals are used to "terminate" a conductor mechanically by crimping or soldering to a component. Crimp terminals, like splices, provide a quick and easy connection, without the need for soldering.

    Selecting a terminal

    Wire terminal connectors are available in various shapes, materials and mounting types. There are also specific colour codes to them that designate the size. When choosing a terminal, here are some points to consider:

    • Receptacle size
    • Wire/cable size (AWG/mm²)
    • Termination method
    • Terminal orientation
    • Insulation type
    • Operating temperature
    • Terminal material

    Understanding wire and cable sizing can be tricky when you are confronted with unfamiliar sizes in the form of millimetres (mm) or American Wire Gauge (AWG). Use our helpful AWG Conversion Calculator to determine the diameter or Cross-Sectional Area of your wire.

    What are crimp connectors?

    Crimp Connectors are a form of electrical connection which is formed by reshaping the wire. Wire crimps are sometimes referred to as a cold welding. Crimping is used to terminate a wire and to attach a connector, such as a ring terminal. Crimping is achieved using a crimp tool. There are various levels of crimping and a well-performed crimp can provide a seal around the wire which prevents moisture getting in. This enables the connection to last longer and avoid corrosion.
