The internal structure of the OBDII connector includes pins, sockets, insulation materials, and shielding layers. Needles are usually made of high-quality metal materials to ensure good conductivity and durability. The socket part adopts a design that matches the pins to ensure that the pins can be firmly inserted and maintain good contact.
Insulation materials are used to isolate between pins and between pins and the casing to prevent electrical short circuits and electric shock risks. The shielding layer is used to reduce the impact of electromagnetic interference (EMI) and radio frequency interference (RFI) on diagnostic communication, ensuring accurate data transmission.
Protection level and durability of OBDII connectors
OBDII connectors typically have a high level of protection, such as IP67 or higher, which means they can resist the intrusion of dust and water. This level of protection ensures that the connector can maintain good performance even in harsh working environments.
In addition, OBDII connectors also have good durability. They can withstand harsh conditions such as frequent plugging and unplugging operations, vibration, and temperature changes without damage or affecting performance. This durability ensures that the connector can work reliably for a long time, providing a stable diagnostic interface for technicians.
