Introduction to the principle of terminal crimping

Crimping open terminals is a skill that can efficiently and easily create a durable connection with minimal training. There are various crimping effects on the market. Perhaps one of the most exciting fundamental subject areas for electronics practitioners is connectors. There are so many different types of connectors on the market today that it is often difficult for users to know what to buy, especially when buying for general use or for stock.

1. What is crimping?

Crimping is a process in which pressure is applied to the contact area between the wire and the terminal to form it and achieve a tight connection. Solderless connection technology was first proposed by AMP in 1941.

2. Requirements for crimping

Provides an inseparable, long-term reliable electrical and mechanical connection between the crimp terminal and the wire. The crimp should be easy to manufacture.

3. Advantages of crimping

✸The crimp structure suitable for a specific wire diameter range and material thickness can be obtained by calculation.

✸It can be used for crimping of different wire diameters only by adjusting the crimping height

✸Low cost through continuous stamping production

✸Stable performance in harsh environments

4. crimping principle

During the crimping process, the conductor is squeezed by the sleeve and deformed in both the longitude and latitude directions, forming a cold weld.

5. crimping process

✸The crimping tool is opened, the terminal is placed down, and the wire is brought into place by hand or mechanical equipment.

✸The upper knife moves down and presses the wire into the barrel.

✸The barrel is bent with the upper knife and formed by crimping.

✸Set crimp height ensures crimp quality.
