Abstract
The disclosed embodiments relate generally to a multi-conductor ribbon cable provided for power and data transmission to a network of devices. The multi-conductor ribbon cable is keyed for mating with a modular connector. The conductors of the multi-conductor ribbon cable are connected to the network of devices via insulation displacement members and spring connectors contained within a modular connector.
Claims25
A multi-conductor cable for use with a power and data transmission network, the network comprising a plurality of nodes wherein a node comprises at least one of a modular connector and an external electrical power source, or a modular connector, a network interface, and an external electrical power source, and a modular connector, a network interface, and an industrial control, the cable comprising:
- an insulating material forming the body of the cable, the body having at least one of a web forming a spaced apart relation to adjacent conductors greater than the spaced relation between at least two other conductors;
- one or more power conductors disposed within the insulating material extending parallel to one another for transmitting network power to the devices;
- one or more power conductors disposed within the insulating material extending parallel to one another for transmitting switched power to the devices;
- at least two signal conductors for transmitting network signals disposed within the insulating material extending parallel to one another and offset a first distance from the power conductors to minimize electromagnetic interference.
A powered data network comprised of a plurality of interconnected nodes, wherein each of the plurality of nodes comprises at least one of a modular connector and an external electrical power source, or a modular connector, a network interface, and an external electrical power source, and a modular connector, a network interface, and an industrial control device, sharing electrical power and data, the cable comprising:
- an insulating material forming a body of the cable, the body having at least one of a web forming a spaced apart relation to adjacent conductors greater than the spaced relation between at least two other conductors;
- one or more switched power conductors distally disposed within the insulating material extending parallel to one another for transmitting control power to the nodes;
- one or more network power conductors disposed within the insulating material extending parallel to one another for transmitting network interface power to the nodes;
- at least two network data signal conductors for transmitting data between the nodes disposed within the insulating material extending parallel to one another and offset a first distance from power conductors to minimize electromagnetic interference.
A power and data cable system, the system comprising:
- a multi-conductor cable;
- a plurality of modular connectors distributed along the multi-conductor cable;
- a plurality of nodes connected to the multi-conductor cable via corresponding modular connectors, wherein a node comprises at least one of a modular connector and an external electrical power source, or a modular connector, a network interface, and an external electrical power source, and a modular connector, a network interface, and an industrial control device.
