Crimp Profile and Wire Gauge Crimping tools are designed according to the wire gauge they can accommodate, therefore American Wire Gauge (AWG) is an important concern. Just as crucial is the kind of terminal being crimped, since each has a unique crimp profile that necessitates the use of a certain die. Finally, the force required to crimp the connection also plays a role in determining which tool you should buy.
There are two types of crimping tools: open-end and closed-end. Open-end tools have a slot on one end through which you insert the wire before closing the tool over it. The other end has a flat surface that presses against the insulation on the wire while the tool is being rotated. This type of tool is used for general purpose crimps. Closed-end tools have a cylindrical cavity at one end through which you insert the wire before closing the tool over it. These tools are made for specific applications where space is an issue or where close tolerances must be maintained. For example, they're commonly used by hobbyists who build projects with metal components because they don't need to be removed from the workpiece after crimping.
American wire gauges consist of 14, 16, 18, 20, 22, and 24 AWG copper or aluminum cable. Each cable size requires its own tool.
Wire gauges 18–14 can be accommodated by the terminals we've given. Remove 1/4" of the insulation off the wire before crimping it to the terminal with the appropriate terminal crimping tool. These are roll crimp terminals. Painless sells this sort of terminal crimper with the component number 70900. It costs about $10.
For heavier gauge wiring, you'll need a different sort of crimping tool. These tools have several pairs of metal jaws that open and close around the conductor to be crimped. As each pair of jaws closes over the conductor, a knife blade or other sharp edge is brought down on it to crimp the conductor against the next portion of the connector.
The best tool for heavy gauge work is called a cable termination tool. These tools are available from specialty tool suppliers and electrical supply houses. They usually cost between $20 and $100.
Crimping tools should never be used on heavier gauge wiring than what their design allows because they won't give you enough control over the force you're applying to the terminal. If you apply too much pressure, the conductor could break.
Always follow manufacturer's instructions when using any sort of terminal crimping tool. Most companies that make these types of products will have recommendations as to how much pressure should be applied when using their specific tool.
Crimp tools are a diverse group of devices that are used to attach materials or components by pushing them together and generating a seal or crimp. Attaching connections to the ends of electrical wires is one of the most prevalent applications for crimping tools. The two main types of crimping tools are manual and automatic.
Crimp tools can be divided into three general categories based on how they work: single-use tools, single-action tools, and multi-action tools.
Single-use tools are the simplest type of crimper and are only capable of creating a single permanent attachment point before they must be replaced. These tools consist of a metal barrel inside of which a number of spring-loaded pins are mounted at equal distances from one another. When not in use, these tools should be stored with their barrels exposed so that they can be placed back in storage mode when needed.
Single-action tools are designed to create a single attachment point but do so in a multiple step process. In this type of tool, the user first places the end of one wire against the shoulder of the tool. Then they place the other end of the wire next to it so that both ends are facing the same direction. Finally, the user pulls the ends of the wire toward themselves until the crimp connects the two wires together.
A 1mm OD crimp tube of any length is appropriate for use with finer strands of beading wire (. 007 to. 014), 2mm OD crimps are ideal for. 019, and 3mm OD crimps are ideal for heavier.020-.037 gage wire.
Crimp tubes are available in various lengths and diameters. To determine how many inches of tubing you need, multiply the desired diameter by 3.3. For example, if you want a tube that will fit a 0.100" diameter bead, then you would need a 33rds inch long tube.
Most jewelry makers use between 6 and 12 inches of tubing for most beading projects. Longer or shorter lengths can be used depending on the project. Crimp covers are available in different sizes for varying the appearance of your finished product.
The best way to decide which size crimp cover to use is by measuring the inside diameter of your bead strand. If it's less than the inside diameter of your chosen tube, then you need a smaller-sized tube. If it's more, then you need a larger-sized tube.
Also check the packaging for instructions on how to measure the inside diameter of your bead strand. Some packages include special tools for doing so while others don't.
The Value of Crimp Size If you use a crimp with an inner diameter that is too large for your beading wire, even after you shut it with pliers, the crimp may not effectively hold the wire. As a result, they are more difficult to conceal with a crimp cover. It may also make your designs appear unprofessional.
The only time you would want to use a crimp size larger than necessary is if you were planning to use it with heavy-duty wire. Then, the extra thickness of the metal gives it more strength to hold the bead without breaking.
Crimp covers fit over the end of the crimp tool to protect the design on its surface and provide a smooth finish. They are easy to use with any crimping tool. Simply place the cover over the tool before using it to secure jewelry-grade wire. When removing the cover, be careful not to pull it off completely or you will lose access to the crimp tool's grip.
There are two types of crimp covers: plastic and metal. Metal ones are usually shaped like a half-shell with a hole in the middle for the handle of the tool to pass through. They are available in different sizes for different tools. Plastic ones look similar, but instead of a hole, they have a slot with a locking mechanism inside them. These covers can be reused but might require replacement parts to do so.
Both types of covers work well to protect finished jewelry pieces.
A crimper is required to perform a correct crimp. This is because crimping it also presses a locking tab, which is difficult to achieve with pliers. Regular pliers will suffice. If you want it to appear nice, poke a tiny nail or screwdriver into the crease where the terminal's pieces meet. This gives the impression that a bolt is holding them together.
Crimps are used to secure two wires together inside of a conductor, such as an electrical wire or cable. There are three basic methods for securing two wires: bare copper, solid core, and stranded core. The type of crimp used depends on which type of material is being joined. For example, if two bare copper wires are to be connected, use sharp tips to prevent cutting through the insulation later. If two solid core wires are to be connected, use flat-head screws to avoid damaging the inner cores. Finally, if two stranded-core wires are to be connected, use split collets or specialized equipment.
The first step is to prepare the ends of the wires that are going to be connected. Cut off any excess length of wire and remove any oxidation or heat-treated metal using a fine-tipped wire brush. Clean the area around the connection site with alcohol to reduce the risk of corrosion. Do not connect wires that may feed electricity into live circuits!
