Understand the Process of Ring Terminal Crimping

August 31, 2021 2 min read

Ring terminals are an essential part of the electrical circuit when forming new connections or repairing the existing ones. This makes it important for you to understand the whole process of ring terminal crimping.

WHAT IS A RING TERMINAL?

Ring terminals are connectors for electrical cables. They are designed to connect the end of an electrical cable to a circuit point.

Airplanes have dozens of electrical components, all of which require power. To hardwire an electrical component, a ring terminal may be used. An electrical cable may plug directly into the back of an electrical component on one end and a circuit point on the other end. To connect the electrical cable to the circuit point, a ring terminal may be used.

It is a terminal with an open space fitted over the stud. The result of this setting is a solid connection without the risk of its frequent disconnection. Instead, people use it for longevity and easy use of the connection.

Of course, there are other types of connectors available for electrical cables. While they are all used to connect the end of an electrical cable to a circuit point, ring terminals have a unique design that distinguishes them from the rest. They are known as “ring terminals” because they feature a circular ring at the end.

STEP 1: SELECTING THE RING TERMINAL:

Before you continue forming the new connection, you will have to choose the right ring terminal from the insulated and non-insulated options available.

Insulated: provides multiple installation options, but the connection might not be very secure.

Non-Insulated: economical, usable in high temperatures, visible crimp point for better connection

STEP 2: STRIP THE WIRE

Measure the length of insulation in the ring terminal to find the exact measurement for stripping. Now place your stripping tool at the desired distance, twist, and pull the insulation to reveal the copper wire beneath.

STEP 3: INSERT THE WIRE INTO THE TERMINAL:

Now, you should insert the exposed copper wire into the ring terminal. Keep pushing it inside until the insulation of the ring terminal comes in contact with the wire’s insulation.

STEP 4: CRIMP THE TERMINAL:

Use the crimping tool to form a secure connection by placing the end of the terminal inside the crimping tool. Make sure that the casing must be inside the middle of the tool's rise. Apply pressure to ensure a connection.

STEP 5: CHECK THE CONNECTION:

To check if you have crimped the ring terminal properly, you can pull the wire slightly. If it remains inside, you might wait to add a bit more pressure so you can be sure of your connection.
