Structural characteristics of  OBD2 16 pin to open end cable

OBD2 16 pin to open end cable is a special cable used for automotive diagnostic systems. The following is its related introduction:

Structural characteristics

Interface type: One end is a standard OBD2 16 pin plug, usually with a plastic shell and 16 metal pins inside, used to connect with the vehicle's OBD2 interface. It has good conductivity and mechanical strength, ensuring the stability and reliability of the connection. The other end is an open end without a fixed connector, making it easy for users to customize connections according to specific needs, such as connecting to terminals of specific testing equipment, data acquisition modules, or other electronic devices.

Internal circuit: It contains multiple core wires that are used to transmit different signals and power sources. Common types include power lines, ground lines, CAN bus lines, K-lines, etc. The core wire is usually made of copper material to reduce resistance and improve signal transmission efficiency, and each core wire has an independent insulation layer to prevent signal interference and short circuits between each other.

Shielding layer: In order to improve anti-interference ability, OBD2 16 pin to open end cables generally have a shielding layer. The shielding layer is usually made of materials such as metal woven mesh or aluminum foil, which can effectively block the interference of external electromagnetic radiation on the internal signals of the cable, and also prevent the signals inside the cable from generating electromagnetic interference to the outside, ensuring stable transmission of signals in complex electromagnetic environments.

Outer sheath protection: The outer sheath of cables is generally made of plastic materials with good flexibility and wear resistance, such as polyvinyl chloride (PVC) or polyurethane (PU). This kind of outer skin can protect the internal core wires and shielding layer from external physical damage, such as wear, compression, stretching, etc., while also having certain waterproof and dustproof performance, suitable for various environments inside the car.
