This application is filed on June 6, 2007 and is entitled US Patent Application No. 60 / 933,358 entitled “VIRTUAL ELECTRICAL AND ELECTRONIC DEVICE INTERFACE AND MANAGEMENT SYSTEM”; Filed on June 6, 2008 and claims priority to US Patent Application No. 12 / 134,454 entitled “HYBRID CABLE FOR CONVEYING DATA AND POWER”. These patent applications are hereby incorporated by reference.

  It is the goal of many developers to form an integrated network that handles both digital communications and power supply throughout the electrical system of a vehicle or other man-made structure. The properties of the physical connection elements that connect the various electrical / electronic devices that make up the networked electrical system are very important. Preferably, the physical connection element facilitates the construction, maintenance, and simplification of networked electrical systems in both data communication and power supply.

  Conventional transportation electrical systems, such as those used in mass-produced vehicles, typically use a wire harness with a dedicated wired circuit to distribute power, with each dedicated wired circuit being a separate electrical / Extends from the electronic device to a power supply and / or control switch connected to the device. In addition, most conventional vehicle wiring systems utilize physically separate power conductors (if necessary) and signal conductors. Such conventional wiring systems are usually for specific models, have limited (if any) networking possibilities and do not provide any overall control and data collection functions. Therefore, such a wiring system cannot be easily applied with an integrated network communication and power supply. Furthermore, once production begins, it is very difficult and expensive to change a wiring system that uses a fixed wire harness.

  Another drawback of conventional vehicle electrical systems is that the chassis or frame of the vehicle can be used as a common neutral connection (ie ground connection) for multiple electrical circuits (particularly common in the automotive field). It is widely used and implemented. This has been done since the early days of vehicle development, probably for reasons of cost control. However, the use of a vehicle frame or chassis as a ground connection or neutral point connection can cause problems. First, the ground connection of the transportation means to the frame or chassis tends to loosen during the life of the transportation means. As the ground connection is loosened, the voltage drops before and after the deteriorated connection, which hinders the power supply of the system. In addition, loose ground connections can cause electromagnetic noise that may be captured as "noise" by other subsystems in the vehicle, such as the vehicle's radio or acoustic system. . If the data network is in a vehicle, such electromagnetic noise can interfere with network communication operations.

  Currently, when microcontrollers and other electrical / electronic components are interconnected within a vehicle, the interconnection is usually via a local bus that is device specific (eg, across the instrument panel). Either through a dedicated low speed bus such as using the Controller Area Network (CAN) protocol. Such interconnections are expensive to design and typically depend on dedicated architecture and software. In addition, these interconnections generally cannot accommodate data collection related to comprehensive diagnosis, fault detection, and maintenance due to limited data transfer rates, at least in part.

  Higher data rates are needed to better incorporate the large number of electrical devices, sensors, and controls used in modern transportation into the network. When the data transfer rate becomes good, the individual devices can be sequentially connected to each other (for example, “connected in a daisy chain”), and can be controlled and monitored at a high level using a host computer. Also, eliminating electromagnetic noise is important to achieve the desired data transfer rate.

  For high-speed networking of computers, the widely used 10Base-T system, 100Base-T system, and 1000Base-T (Gigabit Ethernet (registered trademark)) (Gigabit Ethernet (registered trademark)) system are used. (Registered trademark) (Ethernet (registered trademark)) "and the like that use standard networking physical connectivity methods (standard networking physical connectivity methods) are known. For example, it is insufficient to network most of the electric / electronic devices constituting the electric system of a mass-produced automobile. This is because these physical connections usually cannot satisfy the power supply aspect. For example, Category 5, 5e, 6 cables that are typically used for 10Base-T, 100Base-T, and 1000Base-T physical connections inherently have limited power capacity, and this power capacity is It is insufficient to reliably handle the high current devices found, such as automotive DC electric motors, electromagnetic clutches, solenoids, lighting, and the like. Even improved power supply schemes such as Power over Ethernet (POE) generally do not provide sufficient power to the network of electrical systems across the vehicle.

  Accordingly, there is a need for a hybrid cable that physically connects the networked electrical system and satisfies both the data communication and power supply aspects of the networked system.

  In one aspect of the invention, a hybrid cable includes a signal conducting core having at least one twisted pair of signal conductors. A first braided metal power conductor and a second braided metal power conductor are disposed circumferentially around the signal conductor, and an insulating layer is disposed between the power conductors. An outer insulating cover is disposed around the first braided metal power conductive layer and the second braided metal power conductive layer and the core. A first connector located at the end of the hybrid cable has one of a connection pin or a receptacle with a contact for each signal conductor and has a power contact connected to each braided metal power conductor. In one variation, the hybrid cable has two twisted pairs of signal conductors and can transmit up to 10 megabits / second (up to 10 megabits per second) or up to 100 megabits per second (up to 100 megabits per second). . In another variation, the hybrid cable has four twisted pairs of signal conductors capable of sending up to 1000 megabits / second (up to 1000 megabits per second) of data. The signal conducting core can have one of an insulator or a reinforcing member disposed inside the first power conductor, with the twisted pair of signal conductors disposed within the core. The hybrid cable can further include a second connector disposed at the second end of the hybrid cable, wherein the first braided power conductor, the second braided power conductor, and the signal conductors of the twisted pair are each It extends continuously from the first connector to the second connector.

  In another variation, the hybrid cable has at least one twisted pair of signal conductors with a metal shield disposed around the signal conductors. A first metal power conductor and a second metal power conductor are disposed substantially parallel to the signal conductor, and an outer insulating cover is disposed surrounding the signal conductor, the metal shield, and the power conductor. A connector disposed at the first end of the hybrid cable has one of a connection pin or receptacle for each signal conductor and a contact connected to each power conducting layer. In one variation, the hybrid cable has two twisted pairs of signal conductors that can carry up to 10 megabits / second of data. In another variation, the hybrid cable has four twisted pairs of signal conductors, which can carry up to 1000 megabits / second of data. The hybrid cable can have a second connector disposed at a second end of the hybrid cable, wherein the first metal power conductor, the second metal power conductor, and the twisted pair of signal conductors are each It extends continuously from one connector to the second connector.

  In another aspect, a vehicle comprising an electrical system having an electrically activated sensor and a power powered device comprises at least one hybrid cable having a signal conductor for transmitting data and a power conductor for conducting power. The signal conductor can send up to 10 megabits / second of data. An outer cover is disposed over the signal conductor and the power conductor, and a plurality of devices powered by electric power are sequentially connected using a hybrid cable.

  Referring now to the drawings, like reference numerals have been used throughout to designate like elements. Various views and embodiments of hybrid cables for transmitting data and power are shown and described, as well as other possible embodiments. The figures are not necessarily drawn to scale, and in some cases the drawings are exaggerated and / or simplified in several places for illustrative purposes only. Those skilled in the art will appreciate many possible applications and variations based on the following examples of possible embodiments.

  Referring now to FIG. 1a, a schematic diagram of a hybrid cable 20 according to the present disclosure is shown, which is a digital signal and power throughout a networked electrical system in a vehicle or other man-made structure. Is configured to carry both. In this application, the term “transportation” includes, but is not limited to, automobiles, trucks, unicycles, trains, light rail vehicles, monorails, aircraft, helicopters, boats, ships, submarines, and spacecraft. Any movable man-made structure can be pointed out. The term “other man-made structures” can refer to immovable man-made structures including, but not limited to, office buildings, commercial buildings, warehouses, apartment buildings, and single-family homes.

  The hybrid cable 20 includes a first inner conductor set (eg, conductor 114 in FIG. 2a) that carries digital data and a second inner conductor set (eg, conductors 104, 108 in FIG. 2a) that carries power (current and voltage). ). A connector member 24 is provided at each end of the cable portion 22. Each connector member 24 has a plurality of first electrical terminals 26 attached to the connector member 24 and operably connected to each of the first internal conductor sets, and a second internal portion attached to the connector member 24 And a plurality of second electrical terminals 28 operably connected to each of the conductor sets. Of course, the first electrical terminal 26 and the second electrical terminal 28 of one connector member 24 are always electrically connected to the first electrical terminal and the second electrical terminal of the other connector member. Since they are connected, the cable 20 carries a data signal from the terminal 26 at one end to the terminal 26 at the other end, and carries power from the terminal 28 at one end to the terminal 28 at the other end. Is possible. In some embodiments, the hybrid cable 20 includes a waterproof connector (not shown) that meets a particular ingress protection standard (e.g., that qualifies as an IP-67 or equivalent level protective seal). This ingress protection standard can provide a robust interface to connected network devices.

  The power carried by the power conductor and power terminal 28 of the hybrid cable 20 can take the form of either a direct current or an alternating current at a desired voltage or in a desired voltage range. For example, some hybrid cable implementations only need to accommodate 12 VDC power applications, while other implementations have higher voltages, such as 24 VDC, There may be a need for DC 48 volts, AC 110 volts / AC 220 volts, etc. at 50 Hz / 60 Hz. In some embodiments, the voltage / power rating of the hybrid cable is different to use a color coded cable portion 22 or connector member 24 and / or to eliminate the possibility of connecting devices that are not power compatible. Identification is made by using a connector member 24 and / or terminals 26, 28 that are shaped and keyed.

  As described further below, in some embodiments, the data conductors and data terminals 26 of the hybrid cable 20 are configured to support one or more high-speed network communication protocols. For example, the hybrid cable 20 can support various levels of Ethernet (eg, 10baseT, 100baseT, and 1000baseT). In other embodiments, protocols such as Universal Serial Bus (USB) protocol, Firewire, CAN, and Flexray may be supported in addition to or as an alternative to Ethernet. In yet another embodiment, the connector member 24 may be manufactured to aerospace standards from a corrosion resistant material having a temperature rating suitable for harsh application environments. In yet other embodiments, the cable portion 22 can have a matching cladding and is shielded enough to maintain crosstalk or other noise at a level that does not interfere with network data traffic. And may be coated.

  In some variations, the hybrid cable 20 incorporates neutral wiring into the single cable concept to prevent ground loops, reduce noise, and improve reliability. As already explained, automobiles, boats, aircraft and similar environments have traditionally used a metal chassis of the vehicle as a return path for the DC operating voltage. This is mainly done as a cost-cutting measure, but it can cause problems downstream. For example, multiple electrical connections to ground can be in different galvanic potential states depending on the finish and composition of the materials used, which accelerates corrosion when already in a poor operating environment. There is a fear. The electrical resistance of a circuit can change over time, thereby changing the voltage transmitted to the same common ground and often causing electrical noise between circuit paths. Thus, by using the hybrid cable 20 as disclosed herein, these problems are minimized or eliminated. And it is that the hybrid cable 20 is configured as a protected ground wire with airtight and reliable connections, which insulates the return path of the electrical circuit and minimizes electrical crosstalk caused This is because it is designed to eliminate or eliminate.

  Referring now to FIG. 1b, there is shown a schematic diagram of a hybrid cable 20 that physically connects within a networked electrical system of vehicles. In this embodiment, the electrical system 30 has a network controller 32, a hybrid data / power switch 34, and three device modules 36, 38, 40.

The controller 32 also has a plurality of power terminals 48 for receiving power 50 from the power source 52. The controller further includes a cable interface 54 that includes a terminal for transmitting / receiving the digital data signal 44 and another terminal for transmitting power 50. The switch 34 has one input port 56 and three output ports 58, each port having a cable interface 54, which has a terminal for transmitting / receiving digital data signals 44, power Including other terminals for receiving 50 (for input ports) or sending (for output ports). Each device module 36, 38, 40 is operably connected to an electrical / electronic device, in this case a light 60, a gas gauge sender 62, and a tachometer 64, thereby connecting to the network controller 32. A low level interface is provided that allows the devices 60, 62, 64 to be monitored and operated.

  Still referring to FIG. 1 b, the hybrid cable 20 is connected between the cable interfaces 54 of each network component 32, 34, 36, 38, 40. The physical configuration of the cable interface 54 is such that the end members 24 of the hybrid cable 20 are interdigitated to provide electrical continuity between the appropriate data terminals or power terminals of the devices at each end of the cable 20. Have been chosen to bring. This provides a physical connection across the network for both the digital data communication and power supply aspects of the network. That is, the data communication signal 44 is allowed to travel bidirectionally from the controller 32 to the device modules 36, 38, 40 (and vice versa) via the switch 34, while at the same time power is routed through the switch. Are distributed from the controller to the device modules and finally allow the devices 60, 62, 64 to be fed into these devices for operation.

As shown in the figure, the connector pin 132 and the pin receptacle 126 are arranged in the connector 116 on the radially inner side of the annular recess 122. A contact 128 is disposed inside the pin receptacle 126. Pins 132 and contacts 128 form a signal path through connector 116. Pins 132 and contacts 128 may be connected to the twisted pair of conductors 114, respectively. In one variation, one pin 132 and one receptacle 126 may be provided for each twisted pair of signal conductors 114 in the cable 100.
