Security cable, a method for making the same and a method for securing an electronic device
A security cable for electrically connecting an electrical device, such as, for example, a digital camera, a cam-corder, digital audio player, or like device are provided. Also provided is a method for making the security cable and a method for securing the electrical device using the security cable. A housing, or tubing, may be provided which may have one or more electrical wires. Preferably, the security cable may have six signal-transmitting wires, each of which may transmit a different type of signal. The signal-transmitting wires may be wound around a metal cord within the housing in a spiral manner. The metal cord may have a tensile strength which may prevent cutting of the security cable by conventional tools, and may, therefore, prevent theft of the electrical device from a display area.
1. A security cable to electrically connect and to mechanically secure an article to prevent theft of the article from a display area, the security cable comprising:
a plurality of wires to electrically connect the article wherein each wire has a core wherein the core is separately encased within an insulating material without connection to any other wire of the plurality of wires wherein the core has a diameter and the insulating material has a thickness wherein the thickness of the insulating material is greater than the diameter of the core and further wherein a first wire in the plurality of wires transmits a first signal and a second wire in the plurality of wires transmits a second signal;
a metal cord to mechanically secure the article wherein the metal cord has a length defined between a first end and a second end wherein the metal cord has a tensile strength of at least 400 pounds wherein each of the plurality of wires is independently wound around the length of the metal cord at a pitch that is angularly oriented with respect to the length of metal cord without electrical connection between the metal cord and the plurality of wires;
a housing having a length defined between a first end and a second end wherein the housing has walls enclosing an interior of the housing wherein each wire and the metal cord extend within the interior of the housing from the first end of the housing to the second end of the housing wherein each wire is located between the metal cord and the housing wherein the housing is made of a nonconductive material wherein the nonconductive material of the housing is adjacent to the insulating material of each wire; and
a fastener connected to the first end of the metal cord to mechanically secure the article wherein the fastener extends from the first end of the metal cord.
2. The security cable of claim 1 wherein the metal cord is constructed from galvanized steel.
3. The security cable of claim 1 wherein the first signal and the second signal are electrical signals.
4. The security cable of claim 1 wherein the core is constructed from a conductive material.
5. The security cable of claim 1 wherein the fastener has a female portion wherein the fastener is attached to the metal cord.
6. The security cable of claim 1 wherein the insulating material for each wire is distinctly colored.
7. A security cable comprising:
a plurality of wires wherein each wire has a core wherein the core is separately encased within an insulating material without connection to any other wire of the plurality of wires wherein the core has a diameter and the insulating material has a thickness wherein the thickness of the insulating material is greater than the diameter of the core and further wherein a first wire in the plurality of wires transmits a first signal and a second wire in the plurality of wires transmits a second signal;
a metal cord having a length defined between a first end and a second end wherein the metal cord has a tensile strength of at least 400 pounds wherein each of the plurality of wires is independently wound around the length of the metal cord at a pitch that is angularly oriented with respect to the length of metal cord without electrical connection between the metal cord and the plurality of wires;
a housing having a length defined between a first end and a second end wherein the housing has walls enclosing an interior of the housing wherein each wire and the metal cord extend within the interior of the housing from the first end of the housing to the second end of the housing wherein each wire is located between the metal cord and the housing wherein the housing is made of a nonconductive material wherein the nonconductive material of the housing is adjacent to the insulating material of each wire; and
a fastener connected to the first end of the metal cord wherein the fastener extends from the first end of the metal cord.
