Main Factors Causing OBD Cable Failure

1. Friction: Wear caused by the quality of materials, times of matching, vibration and other reasons. Including plastic wear and metal wear. Good materials have wear resistance, while poor quality materials have poor wear resistance. If the matching time is frequent, there will be wear with connector of OBD cable. If there is wear with the plastic parts, it may cause matching problems. For example, the matching is difficult, or the connection is not firm. If there is wear with metal parts, the conduction performance may be unideal.

2. Corrosion: External environment always bring corrosion to both plastic parts and metal parts. Corrosion of plastic parts will accelerate wear and fracture, which will cause problems for the matching of OBD cable. The liquid, corrosive substances, and oxidation will lead to the corrosion of metal parts. The corrosion of metal parts will lead to weakening of conductive communication performance. If it is serious, it will also cause the fracture of metal parts, which will lead to the scrapping of OBD cable. Good injection materials can effectively delay corrosion. Metal parts can be with gold or silver plating to delay the corrosion process.

3, Process: Refer to crimping, welding process for metal parts and injection, molding for plastic parts. The main process problems are mechanical failure and electrical failure. If the manufacturing process is poor, it may cause many problem. Like deformation of the joint, or the thickness and hardness of some parts are not up to standard. This will affect the matching and firmness of the OBD cable. The position of metal parts should be accurate. If the process is not good, the position of metal parts will be deviated or even deformed. Therefore, it is necessary to adopt advanced technology in the production process of OBD cable.
