What is crimp terminal?
High-quality crimp terminals: the electrical connection in which you will insert the wire. Stranded wire (not solid core): a metal wire comprised of several smaller wires. Heatshrink Tubing: a plastic tube used to insulate the joint between the electrical connector and the wire.
What is electrical connector?
Electrical connectors are a type of hardware that affixes to a receptacle to complete an electrical circuit and deliver electricity to a piece of equipment. This connection can be between two wires or a wire to a terminal.
Do you need a crimping tool?
You will need a specialized crimping tool. They can look similar to pliers or ratchets. Ratchet crimping tools are typically recommended over plier tools because they produce a more reliable crimp. In either case, crimpers are not one-size-fits-all. There are dozens of variations in shape and mechanical performance.
How to crimp a connector?
The general theory for crimping all types of connectors is to strip a little bit of insulation off the wire. Then, put the connector into a suitably sized space in the jaws, insert the wire, and crimp it down. For non-ratcheting pliers, it’s suggested the connector be re-crimped with the next smallest hole in the jaws.
What tool do you use to crimp wires?
Crimping connectors onto wires requires the right tool, and the most important for this task is – surprise – the crimping pliers. These pliers press the crimping wings of the connector into each other, a task made much easier on the non-ratcheting pliers if you use a rubber band to hold the jaws of the crimping pliers open just enough ...
Why does solder break wire?
Adding solder will cause the wire to break due to the solder wicking up under the insulation and stiffening the wire behind the terminal. Standardize on a connector type and buy the correct crimper for it. They’re expensive, but you will never regret buying one.
How much do ratcheting pliers cost?
At least buy a set of ratcheting pliers on ebay from China. They will be about $30 or so and work really well with a decent range of most crimp sizes. Don’t waste your time with crappy tools.
How to test crimps?
Test your crimps by pulling on the wire. A good crimp will break the wire before it pulls out of the crimp.
Why do I need to drill out two solder cups on a DB-25 connector?
I remember drilling out two solder cups on a DB-25 connector because an engineer misread the mA rating as A on two signals, and the engineer had a custom eighteen+two wire cable ordered up with a six month delay.
What is the pitch of a Dupont connector?
There are a few connector-specific tips for the most common connector types, too. Dupont connectors – those flat, black connectors with a 0.1″ pitch – go together like you think they would, but for larger connectors – VH and XH-style – it’s important to use the right wire gauge and not to squish the square female part of the connector.
How to crimp a red wire?
1. Place 1⁄4 inch (0.64 cm) of the end of the wire into the crimping die. Locate the hole designated for your wire's gauge in the crimping die. For example, if you're crimping a 15-gauge red wire, select the hole designed for a range that covers this gauge range.
How to seal crimp terminal?
Seal the terminal with electrical tape or heat shrink. Use a pair of scissors to remove a small piece of electrical tape big enough to cover the crimp terminal. Wrap about 2 layers of tape over it to help prevent the metal from corroding.
How to connect a wire to a connector?
Carefully place the exposed portion of the wire into the connector. Continue to do so until the insulation makes contact with the barrel of the connector. Make sure the wire is not extending past the barrel more than 1⁄4 inch (0.64 cm). 2. Place the barrel of the connector into the appropriate crimper slot.
What is crimping die?
The crimping die is the piece at the top of the crimper that does the crimping, and almost all crimpers come with one. However, it's important to make sure the die is appropriate for your wire gauge, as each piece is designed for a specific range.
Why buy a ratchet crimper?
Purchase a ratchet crimper for simplicity and durability. Ratchet crimpers have a built-in ratchet, which means all you have to do is apply enough pressure to the handles and the crimper will do the rest. These tools also have wider jaws, which helps them cover more connector surface area.
What does the crimper slot do?
For ratchet crimpers, the crimper slot will align the crimper over the barrel automatically— simply apply pressure to the crimper handles and you're good to go!
How to use electrical connector?
Electrical connectors are necessary to join electric circuits together. But to use an electrical connector, you need to attach it to a wire via crimping. Whether you're joining 2 pieces of wire or a wire directly to an electrical terminal, the quality of the connection depends on how well you crimp the wire to the connector.
Why are hydraulic crimpers so high maintenance?

What size crimps are used for threaded fasteners?
There are many, many variations of crimp, but there are a handful of very common ones, most shown in the image. Crimps designed to fit to threaded fasteners can be simply specified by the bolt size (e.g M4/ ¼”). Others may have different names dependent on the industry and manufacturer (eg lucar, faston, ¼” blade).
What is the best shrink ratio for wire crimp?
Typically 3:1 shrink ratio, adhesive lined heat shrink would ensure that good support of both the wire and crimp is made. A length at least 2 times the crimp barrel will usually give a good grip. Other sleeving can be used- in particular neoprene sleeves (Hellermann Sleeves) also work well.
How many times do you crimp a terminal?
If you are using some of the cheaper/ non-ratchet tools, you may have to crimp each terminal twice, possibly with two settings on the tool. If you need to do this, crimp the conductor end of the crimp first, followed by the insulation. If using heatshrink, or other sleeving.
How are tube terminals made?
Tube terminals are manufactured by cutting a piece tube to length, flattening one end and punching a hole. The tube type tend to be heavier duty and therefore are more common in the larger sizes- for example you might encounter these on a starter motor feed. Open Barrel Un-insulated Crimps.
How are sheet formed terminals made?
The sheet formed ones are manufactured by cutting the material out of flat sheet and then shaping to make a tube on one end . Better quality ones of this type will have thicker material and the seam brazed. Tube terminals are manufactured by cutting a piece tube to length, flattening one end and punching a hole.
Does soldering the rear of a crimp affect the corrosion resistance of the joint?
This stops both moisture and oxygen entering the crimp and therefore prevents corrosion from occurring. If this is correctly carried out, soldering the rear of a crimp (as some people will recommend) will have no effect on the corrosion resistance of the joint as there will be no space for the solder to enter.
Can you twist wire strands together?
It is not recommended to twist the strands together. Carefully place the crimp in the wire in to the tool (you may find it easier to put the crimp into the tool prior to the wire with some crimps), and ensure the wire is seated home. Cycle the tool- if a ratchet tool, until the tool releases.
