Some problems and solutions in automotive wiring harness processing

Cutting process - the results of poor cutting: 1, stripping size is bad: resulting in the next process (crimping) can not be operated properly, which also leads to the failure of the finished product. 2, wire size is bad: wire size is too short, resulting in the finished product line is unqualified. 3, core damage, oxidation: poor crimping, false connection. Defective product handling process: (size bad for example) 1. Operator: found that the size is too short, immediately find the reason for failure, communicate with the inspector to solve the problem, to prevent the emergence of a batch of defective products, and will be the size of the short directly scrapped, shall not be mixed with the qualified products transferred to the next process; the size of the long reworking with the stripper pliers by the inspector to confirm that it is qualified. 2. Inspector: sampling found that the defective products, and required to find out the cause and immediately Rectification and evaluation of defective products will be dealt with, if there is a batch of defective products, it should be immediately shut down for rectification, and reported to the immediate leadership.

Crimping process - the results of poor crimping: 1, pull-off force is too small: the core and the terminal false connection or fall off. 2, generally poor crimping will lead to a large amount of waste of costs, and rework is difficult, very easy to scrap. Defective product handling process: (pull off force is too small) 1. operator: pull off force is too small should immediately stop crimping, and contact the mechanic on the crimping mold rest, reported to the inspector. 2. inspector: the same type of crimped terminals (the last test qualified to find bad), all according to the 2% sampling test, the test found to have defective products will be determined that the batch of all failed to do a good job of marking and isolation, and notification of return to the maintenance.
