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

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.
