Result and Pin Configuration of J1939 to OBD2 Cable

Cable structure and materials

The internal structure of J1939 to OBD2 cable usually adopts a multi-layer design to ensure the stability and durability of data transmission. The core conductor is usually made of high-purity copper, which has excellent conductivity and can reduce signal attenuation and improve data transmission efficiency. The insulation layer is made of high-quality PVC material, which has excellent insulation performance and wear resistance, and can effectively protect the conductor from external environmental interference and damage. In addition, the outer layer of the cable is also equipped with a shielding layer, which can effectively shield electromagnetic interference and further enhance the stability of data transmission.

In terms of material selection, the J1939 to OBD2 cable is also quite sophisticated. The joint part is usually made of high-quality metal materials, such as gold plating or nickel plating, to enhance conductivity and corrosion resistance. At the same time, the cable sheath is also made of high-quality PVC or nylon materials, which not only have good flexibility, but also can resist the erosion of harsh environments such as oil and water stains, ensuring the stability and reliability of the cable in long-term use.

Connector and Pin Configuration

The connector part of J1939 to OBD2 cable is one of its core components, which directly affects the connection quality and data transmission efficiency between the cable and the equipment. At the J1939 end, cables typically use 9-pin connectors that comply with the standard configuration of the J1939 protocol. At the OBD2 end, a 16 pin connector is used to be compatible with the OBD2 interface on passenger cars.

In terms of pin configuration, the 9 pins of the J1939 connector correspond to different signal lines, such as power lines, ground lines, CAN bus lines, etc., to support the complex communication requirements inside commercial vehicles. The 16 pin OBD2 connector covers more diagnostic functions, such as emission monitoring, fault code reading, etc., to meet the needs of passenger car diagnostic systems.
