In the world of precision engineering, electrical work, and manufacturing, a crimping tool is an essential tool that serves a variety of purposes. Specifically, a circumferential crimping tool is a tool used for applications where the crimp needs to encircle or cover a terminal completely. Whether you're a professional working on electrical connections, a hobbyist, or someone involved in industrial applications, understanding how and where to use a circumferential crimping tool is key to achieving secure and reliable connections. In this article, we’ll explore what a circumferential crimping tool is, what it's used for, and how it fits into the broader category of crimping tools.
A circumferential crimping tool is used to create a circular, tight seal around the wire and terminal connection. Unlike regular crimping tools, which may only crimp a part of the terminal, the circumferential crimping tool works to apply pressure all around the wire and connector to ensure a strong, uniform, and secure connection. This tool is essential in applications that demand high reliability, such as in heavy-duty connectors, automotive wiring, aerospace, or electrical connections.
The circumferential crimping tool is commonly used in the following applications:
Automotive Wiring: In automotive systems, secure and durable electrical connections are critical, especially in environments subject to vibration, heat, and moisture. Circumferential crimping tools ensure that connections are tight, preventing loosening and ensuring reliability.
Aerospace and Industrial Applications: In industries such as aerospace, where systems must endure extreme conditions, crimping tools are used to make sure that connectors hold up under stress. The uniform pressure applied by a circumferential crimp ensures that connectors don’t fail.
Telecommunications: The network crimping tool often uses circumferential crimping to ensure secure and reliable connections for telecommunications wiring, providing longevity and performance in high-demand networks.
Electrical Systems: When connecting copper wires to electrical terminals or connectors, it’s critical to ensure a secure crimp that provides a high level of conductivity and prevents the connection from coming loose due to physical strain or environmental factors.
Wire Terminals and Splicing: Circumferential crimping tools are particularly important when working with wire terminal crimping tools in splicing, ensuring that connections remain intact and safe.
A crimping tool is used to join two materials together by deforming one or both of them. In most cases, crimping tools are used to attach a connector to a wire or cable. This is achieved by squeezing the crimping tool around the wire and connector, thereby compressing the connector around the wire. The result is a secure, electrical connection that doesn’t require soldering.
Some common applications of crimping tools include:
Wire Terminations: One of the most common uses of a crimping tool is to attach a connector to the end of a wire. This is often used in electrical work, where connectors are needed for easy connection and disconnection of circuits.
Electrical Connectors: In industrial and automotive applications, crimping tools are used to attach electrical connectors to wires. This method provides a strong and durable connection that can withstand vibrations and other stresses.
Network Wiring: Crimping tools are used to create custom network cables for communication systems. Network crimping tools are specialized for Ethernet cables, and they allow for both the proper insertion of pins and the creation of a secure seal around the wire.
Plumbing: Although most commonly used for electrical connections, crimping tools are also used in plumbing to attach fittings to pipes, particularly in systems using copper or other metal piping materials.
Crimping tools are used in many industries and applications, especially when a quick, secure connection is needed. Some common areas where crimping tools are used include:
Automotive Wiring: Whether it’s for lighting systems, sensors, or other electrical components in a vehicle, crimping tools are an essential part of the automotive technician’s toolkit.
Electrical Work: From household electrical systems to large industrial installations, crimping tools are used extensively to connect wires and terminals. They ensure that the electrical connections are safe and reliable.
Aerospace: The aerospace industry relies on crimping tools for aircraft wiring, where secure connections are necessary to prevent failures during flight.
Telecommunications: The creation of custom cables for phone lines, internet networks, and other communication systems is possible with the use of a crimping tool. The network crimping tool ensures that connections are made properly for smooth data transmission.
The main purpose of a network crimping tool is to attach connectors to the ends of network cables. This is particularly crucial for making custom cables in telecommunications, where Ethernet cables and other networking cables are required for connecting computers, routers, and other devices.
Network crimping tools allow users to strip the wire’s insulation, insert the wires into a connector, and apply the necessary force to crimp the connector securely to the wire. This is essential for establishing a proper network connection.
When using a crimping tool, it’s important to use the correct size die and tool for the application. For instance, using the wrong die size can lead to an improper crimp, which may cause the connection to fail. Additionally, make sure to use the right crimping tool for the wire gauge and terminal type to ensure a secure connection.
Lubrication is also essential in some cases when using a crimping tool for metals that may create friction, such as copper or aluminum. This helps to reduce wear on both the wire and the tool and ensures a cleaner crimp.
Crimping is used because it is an efficient, quick, and reliable method of joining two materials, such as wires and connectors. It is preferred over soldering in many cases because it doesn’t require heat, which could potentially damage sensitive components. Additionally, crimping provides a mechanical bond that can be more durable than some other methods.
Crimping offers several advantages:
Speed: It’s a much faster process than soldering, especially when making multiple connections.
Durability: Crimping results in a strong, lasting connection that can withstand vibrations, physical stress, and environmental conditions.
Simplicity: The process is simple and requires minimal skill, which makes it suitable for both professionals and DIY enthusiasts.
No Heat: Unlike soldering, crimping doesn’t require the use of heat, which can damage components.
The copper IDC termination is typically used for applications where insulation displacement connectors (IDC) are involved. A wiring scheme for copper IDC terminations is designed to ensure that the connector properly displaces the insulation of the wire to make an electrical connection. Crimping tools are often used in conjunction with IDC connectors to ensure the correct level of pressure and a secure connection.
On a crimp terminal, the conductor should extend past the inspection hole no more than 1/8 inch (3.175 mm). This ensures that the crimp is secure and that there is no excessive conductor length that could cause short circuits or other issues.
On a 110 block, electrical connections for the cross-connect wires are typically made by using punch-down tools and IDC connectors. Crimping tools may be used in some cases to secure the connectors before they are connected to the block.
A device commonly used during soldering to protect components from heat damage is a heat sink. This device draws heat away from sensitive components, preventing them from overheating and getting damaged during the soldering process.
Field-fabricated modular cords are not recommended for use with Cat 5e or Cat 6 cables because they do not provide the same level of signal integrity and reliability as factory-made cables. Crimping tools are typically used to make custom cords, but these cords should be carefully fabricated to ensure the connection is of high quality.
The purpose of soldering flux is to clean and prepare the metal surfaces for the soldering process. It also prevents oxidation and allows for a smooth and strong bond between the solder and the metal.
A circumferential crimping tool is an invaluable tool used to create strong, reliable connections in a variety of industries. Whether you’re working with heavy-duty connectors, network cables, or automotive wiring, using the right crimping tool is crucial to ensure that your connections are secure and long-lasting. By understanding what a crimping tool is used for, how to choose the right tool, and where it is applied, you can make informed decisions that lead to successful and professional results every time.
