Description

Technical Field

[0001] The main topic of this article is electrical connector systems. Background Technology

[0002] Modern vehicles increasingly rely on sophisticated electronic control systems to manage various engine functions, including fuel injection, ignition timing, emissions control, and turbocharging. At the heart of these systems is the engine control unit (ECU), a microcontroller-based device that interacts with numerous sensors and actuators throughout the vehicle. Communication between the ECU and these peripheral components is typically facilitated via serial communication buses, such as Controller Area Network (CAN), Local Interconnect Network (LIN), or similar proprietary or standardized networks.

[0003] In such systems, proper signal integrity and network performance are essential for accurate and timely data exchange. To achieve this, terminating networks are typically used at the ends of the communication bus to match impedance, reduce reflections, and ensure reliable data transmission. These terminating networks usually include resistors and / or capacitors configured on the ECU's printed circuit board (PCB).

[0004] However, implementing termination and signal conditioning circuitry directly on the ECU's PCB presents several challenges. First, the ECU is a highly space-constrained environment where available space on the PCB is extremely valuable. The addition of termination networks and associated signal processing components consumes precious board space that would otherwise be allocated to basic processing, memory, or power management components. Second, the design and integration of these components increases the overall complexity of the ECU, raising design time, cost, and potential points of failure in the system. Summary of the Invention

[0071] In the illustrated embodiment, the data module 400 is located at the center of the mating end 230 of the plug housing 210. The power contact 300 is located on a first side of the data module 400, and the end node termination module 500 is located on the opposite second side of the data module 400. In alternative embodiments, other arrangements are possible. In an exemplary embodiment, the end node termination module 500 may be electrically connected to one or more of the data module 400 and / or the power contact 300.

In an exemplary embodiment, signal lines 404 are a stranded pair of signal lines. In an exemplary embodiment, signal lines 404 are an unshielded stranded pair of signal lines. Signal contacts 402 terminate at the ends of signal lines 404. For example, signal contacts 402 may be crimped to the ends of signal lines 404. In an exemplary embodiment, a portion of the insulator 406 is stripped to expose the ends of signal lines 404. A length of signal line 404 is unstretched forward from the insulator 406 to terminate at signal contacts 402.
