The new press-fit and IDC connection technology for automotive applications is a new type of connector that combines industry-proven bonded PCB end and IDC discrete wire connections into a single, simple wire-to-board connection. In the system, such connections are mostly used in discrete wires. This new solution provides designers with a reliable, cost-effective alternative to the current market upper and lower connector, with current ratings up to 6–10A depending on wire size, operating temperature range -40 degrees to 125 degrees.
The benefits of this new modular connector technology include: redundant connection systems that enhance cable retention and PCB bonding capabilities; are highly resistant to extreme temperatures, shock, vibration and thermal expansion; The overmolding and coating processes are compatible and there is no risk of any material intrusion.
These new connectors allow the user to connect two adjacent PCBs with different orientations or positions, which is better than cables that are typically used to jump between two zero-pull connectors, especially This feature is reflected in high vibration applications. It also enables the performance of connectors with large current multi-color discrete lines to be more prominent. It also makes assembly and maintenance of the vehicle easier.
In addition, the dual assembly method allows for pre-installation during the manufacture of the board. This means that the wires can be inserted and pressed in place using any standard tool, or pre-installed, and the user simply presses the connector PCB to complete the final assembly.
Electronic modules used in automobiles used to use complex, expensive, resealed cast metal housings, with a mounting or removal procedure to configure the connector PCB module with a lid and gasket for sealing. Due to modern advanced molding and manufacturing processes, these types of modules have been replaced by integrated, molded plastic housings or covers that are lighter and much cheaper.
