[0002] The subject matter of the present invention generally relates to electrical connector systems.
[0003] Modern vehicles increasingly rely on sophisticated electronic control systems to manage various engine functions, including fuel injection, ignition timing, exhaust aftertreatment, and turbocharging. At the heart of these systems is the engine control unit (ECU), a microcontroller-based device connected to numerous sensors and actuators throughout the vehicle. Communication between the ECU and these peripheral components typically occurs via serial communication buses such as Controller Area Network (CAN), Local Interconnect Network (LIN), or similar proprietary or standardized networks.
[0004] In such systems, proper signal integrity and network performance are essential for accurate and timely data exchange. To achieve this, termination networks are often used at the ends of communication buses to match impedance, reduce reflections, and ensure reliable data transmission. These termination networks often include resistive and / or capacitive components configured for this purpose on the ECU's printed circuit board (PCB).
[0005] However, integrating termination and signal conditioning circuits directly onto the ECU's printed circuit board (PCB) presents several challenges. First, the ECU is a space-constrained environment where PCB space is highly valuable. Integrating termination networks and associated signal processing components consumes valuable PCB space that could otherwise be used for critical processing, memory, or power management components. Second, the design and integration of these components increase the overall complexity of the ECU, leading to increased design time and costs, as well as potential points of failure within the system.

The connector includes a common-mode end-node termination module housed in the second module channel. The common-mode end-node termination module includes a termination module housing with a pocket. The common-mode end-node termination module includes a common-mode signal processing assembly housed in the pocket. The common-mode signal processing assembly includes an end-node printed circuit board (PCB) with common-mode control circuitry. The common-mode signal processing assembly includes a common-mode signal processing component mounted on the end-node PCB to process signals on the common-mode control circuitry. The connector includes jumper contacts held by the connector housing.Each bridge contact comprises a signal contact connector that is electrically connected to the corresponding signal contact, and an end-node connector that is electrically connected to the common-mode end-node termination module to electrically connect the signal contacts to the common-mode control circuitry within the connector.

In an exemplary embodiment, a housing seal 219 is located in the housing shaft 217 to engage with the sheath 138 when the connector 200 is connected to the head connector 100. The housing seal 219 provides a seal between the connector housing 210 and the head housing 110. The outer housing 216 can surround the sheath 138 of the head housing 110. The inner housing 218 is configured to be inserted into the receptacle 114 of the head housing 110.While the outer housing 216 and the inner housing 218 are separate housing structures configured to be joined together, it is conceivable that in alternative embodiments the outer housing 216 and the inner housing 218 could be integral structures. For example, the outer housing 216 and the inner housing 218 could be formed together to create a single, monolithic, or one-piece housing.
[0031] The connector housing 210 extends between a top 220 and a bottom 222. The connector housing 210 extends between a front 224 and a back 226.

In an exemplary embodiment, the power contact channels 212 and the module channels 214 are open at the rear 226 to allow the power contacts 300 to be inserted into the power contact channels 212, and the data module 400 and the end-node termination module 500 into the module channels 214. The power cables 204 and the data cables 206 extend from the power contact channels 212 and the module channels 214 to the cable end 232 (for example, the rear 226).
[0033] In an exemplary embodiment, the plug housing 210 includes a locking element 240 configured to be lockably coupled to the head connector 100. In the illustrated embodiment, the locking element 240 is located on the top 220. Alternative positions are possible in alternative embodiments. The locking element 240 includes a deflectable lock 242 that is movable between a locked position and an unlocked position. In an exemplary embodiment, the deflectable lock 242 includes an actuator 244 that can be pressed or actuated to move the lock 242 between the locked and unlocked positions. In the illustrated embodiment, the locking element 240 includes a locking cover 246 that covers the deflectable lock 242.In an exemplary embodiment, the locking element 240 comprises a locking detent 248 that can be moved from an unlocked position to a locked position. For example, the locking detent 248 can be moved along the connector housing 210, for example, from front to back or from side to side between the unlocked and locked positions. When the locking detent 248 is in the locked position, it prevents movement of the locking mechanism 242 (for example, into the unlocked position). The locking mechanism 248 can define a position-locking device that is used to ensure the positioning of the locking mechanism 242 and / or to ensure the correct positioning of the connector 200 and the head connector 100 in a mated condition.For example, the locking mechanism 248 can only be moved into the locked position if the connector 200 is correctly plugged into the head connector 100.
[0034] In the illustrated embodiment, the data module 400 is located at a central position at the mating end 230 of the connector housing 210. The power contacts 300 are 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. Alternative arrangements are possible in other embodiments. In one exemplary embodiment, the end-node termination module 500 can be electrically connected to the data module 400 and / or one or more of the power contacts 300. For example, internal contacts or connections can be established between the end-node termination module 500 and the data module 400 and / or the power contacts 300 to enable signal processing within the connector 200.For example, the end-node termination module 500 can perform common-mode signal processing, differential-mode signal processing, or other types of signal processing within the connector 200. This eliminates the need for signal processing to take place on the circuit board 102 connected to the connector 100, thereby saving space on the circuit board 102 and / or reducing its size.
