Contact failure
1.In the cable assembly when using tin or lead contact, is the common problems of wear and tear, when two kinds of metal oxides formed when contact with each other, when test the conductivity or perform other routine test, will not be able to detect this problem, therefore, cable components manufacturers need extra attention to avoid the wear and tear.
2.When the force is not correct, when contact with intermittent failure could occur, there are several reasons why this may cause, such as pollution of the contact, the contact of wear, etc., if the contact has some manufacturing defect, may appear the same problem, for example, crimping pin lock is not sufficient.
Contact line fault
1.Has the pressure welding connection cable components may suffer manufacturing defect, therefore, using tensile test pressure or any other relevant test to test the pressure connection is very important.
2.Improper welding process may be the main reason for the intermittent failures, therefore, must follow the appropriate welding process to ensure a reliable connection.Contact wire fault Witness if cable component respectively two contact or contact and cooperation between wires or combination of components will experience elv connections or no electrical connection. This leads to intermittent failures.
