Crimping Basics

Because they have an impact on the overall effectiveness and dependability of the connection, crimp height, width, draw force, and compression are all significant aspects in terminal crimping.

The amount of material bent during the crimping process is referred to as crimp height. A appropriate crimp height guarantees that the terminal is firmly fastened to the wire and that the terminal and wire have enough electrical contact.

The size of the distorted area on the terminal is referred to as the crimp width. A correct crimp width aids in uniformly distributing the crimp's stress across the terminal, making the connection dependable and strong.

The amount of force needed to pull the terminal away from the wire is referred to as the "pull force." A stronger link is indicated by a greater draw force.

Compression describes the degree of deformation of the terminal during the crimping operation. In order to guarantee that the terminal and wire are linked securely and that there is good electrical contact between the two, a correct compression is necessary.

One method for evaluating the quality of a terminal crimp is the process capability index (CPK). This measurement helps find any problems or places for improvement by comparing the process' actual performance to the desired performance. Measure the process's actual performance (such as crimp height, width, pull force, and compression) and compare it to the desired performance in order to determine CPK. Using the mean and standard deviation of the process performance data, the CPK value is then determined. While a lower score suggests opportunity for progress, a higher CPK value denotes a more capable and reliable process.
