초록 ▼

A network communications system is provided for allowing a group of computer users in a conference room or similar small work environment to access an Ethernet local area network (LAN) and to provide peer-to-peer group networking without connection to a backbone network.The system includes multiple (for example, 4 or 8) client computer ports each including a removable spring loaded cable dispenser carrying an extendible/retractable Category 5 LAN cable terminated with an RJ-45 plug for connection to a client computer's network adapter. Combined power/Ethernet LAN cables connect the system to an enterprise network and to a source of electrical power, and permit cascading of up to three 8-port systems.In use, a computer user pulls out the cable from one of the client ports and inserts the RJ-45 plug into the RJ-45 jack on the network adapter carried by the computer. After completion of the networking session, the user unplugs the cable which is automatically retracted by the spring loaded cable reel. A cable management system is thereby provided which eliminates the tangle or clutter of multiple cables encountered in existing systems.

1. An apparatus comprising:a housing having a side wall and a plurality of internal wells, the side wall defining a plurality of client computer ports, each client port communicating with one of the wells; a cable take-up device removably mounted within each of the wells, each cable take-up device carrying a cable having a first portion and a second portion, the first portion of the cable being fixed relative to the take-up device and coupled within a respective well, the second portion of the cable being extendible from the take-up device, the second portion of the cable having an extremity carrying a computer connection plug adapted to be received by a corresponding jack of a computer system; and multiport network interconnection circuitry within the housing to provide a communications interface between the respective cable first portions in the housing and an external network. 2. The apparatus of claim 1, further comprising a plurality of computer connection jacks mounted in the housing and corresponding in number to the number of wells, each jack being adapted to receive a computer connection plug; and wherein each cable first portion has an extremity carrying a computer connection plug adapted to be received by one of the computer connection jacks within a well.3. The apparatus of claim 2, wherein the multiport network interconnection circuitry is electrically connected to the computer connection jacks in the housing and provides a communications interface between the computer connection jacks in the housing and the external network.4. The apparatus of claim 1, wherein the cable second portion is extendible against a resilient bias and retractable by the take-up device in response to the resilient bias.5. The apparatus of claim 1, wherein the interconnection circuitry comprises a local area network switch, and the computer connection jacks and plugs are of the RJ-45 type.6. The apparatus of claim 1, wherein the multiport network interconnection circuitry further includes a port adapted to be connected to the multiport network interconnection circuitry of a cascaded network communications system.7. The apparatus of claim 1, further comprising a combined power/network cable having a first set of conductors to connect the multiport network interconnection circuitry to a source of electrical power and a second set of conductors to carry network signals between the system and the network.8. The apparatus of claim 1, wherein the housing includes a cover having an outer surface, and the multiport network interconnection circuitry includes light emitters to indicate the status of the computer ports.9. The apparatus of claim 8, wherein the cover carries light pipes positioned relative to the light emitters so as to transmit light from the light emitters to the outer surface of the cover to provide a visual indication to a user of client port status.10. The apparatus of claim 1, wherein each cable take-up device includes an upper surface carrying a handle facilitating removal of the device from the associated well.11. The apparatus of claim 1, wherein the computer connection plug at the extremity of the second portion of the cable includes a resilient pad to absorb shock resulting from the sudden release of the second portion of the cable from an extended position.12. The apparatus of claim 1, further comprising a power supply to supply power at each second end of each respective cable.13. The apparatus of claim 1 wherein the cable comprises:a first group of conductors comprising two twisted wire pairs to transmit data signals, the first group of conductors having a first end and a second end, the first end being adapted to be connected to a data network; a second group of conductors extending generally parallel with the first group of conductors to transmit electrical power, the second group of conductor having a first end and a second end the first end of the second group of conductors being adapted to be connected to a source of electrical power; and an insulative jacket enclosing the first and second groups of conductors. 14. The apparatus of claim 13, wherein the second group of conductors comprise two twisted wire pairs to transmit electrical power.15. The apparatus of claim 13, wherein the first end of the first group of conductors is coupled to a modular RJ-45 connector.16. The apparatus of claim 13, further comprising a first EMI/RFI shield enclosing the first group of conductors.17. The apparatus of claim 16, further comprising a second EMI/RFI shield surrounding the first shield, the second group of conductors being disposed between the first and second shields.
