A typical computer includes a plurality of input and output cables coupled to a back panel of the server, including power cables, data cables, communication lines, and keyboard lines, etc. Cables are used to connect the monitor, printer, speakers and input devices to the processor housing. Flexprint cable is typically used in computer systems to connect, for example, a transmitter on the motherboard to a receiver included in the LCD display device. The transmitter is located in the bottom portion of the notebook computer and the receiver is located in the top portion of the notebook computer. Generally, a flexprint cable includes multiple signal conductors surrounded by flexible layers of insulating tape, such as a mylar tape. Another type of cable typically used in computer systems to electrically connect components is a shielded cable or wire, such as copper. These types of cables using shielded wire include a point-to-point wire connection, a twisted wire pair, or a standard coaxial cable. Power cables are also required to connect the processor housing, and usually the monitor, to a power source. To achieve high performance data transfer interfaces between the host computer system and a given peripheral device, computer users typically use hardware that can take advantage of the small computer system interface (SCSI) protocol. Typically, a computer is provided with SCSI capabilities via SCSI controller cards that connect to the host computer or via a SCSI chip that is integrated as part of the computer's motherboard. Once a computer is provided with SCSI capabilities, the user is able to connect either internal or external SCSI peripheral devices to the computer. SCSI ribbon cables are internally used to interconnect the peripheral devices to the computers controller card or a motherboard's connector. SCSI peripheral devices can be externally coupled to the computer's connector receptacle via an external SCSI cable. Nowadays, many peripherals such as scanners, cameras, printers, network switches, audio players, video player, etc., are connected to computers. The more peripherals that are connected, the more cables of various sizes and colors of cables are used. Computer cables typically provide a monochromatic exterior appearance, often in black, grey or beige. This appearance is typically provided by having an opaque outer insulator about the cable in the desired color.
Typical cables used for cabling computer components are made up of a plurality of electrical conductors, typically wires made of copper, which are insulated individually and then gathered together in a bundle and surrounded by a metal foil and a braided metal wire shield. The braided wire shield or cable shield sleeve typically is further surrounded or is wrapped around a thin metal foil, forming the cable shield. To complete the formation of the bulk cable, the cable shield and insulated electrical conductors and the foil wrap are encased in a vinyl, rubber or similar polymeric insulating sleeve. Typically for computer cables, there are a plurality of individually insulated conductive wires. The wires typically correspond to the various pins used in a computer connection and are individually held in a connector for easy connection to the appropriate computer or peripheral. The individual wire insulation is often color coded for ease of following the connections through the cable. In a personal computer system, a signal cable is connected between a monitor and a computer main body conveying a video signal and a synchronizing signal from the computer main body to the monitor. A coaxial cable is generally used as the signal cable thereby transmitting stable signals and preventing electromagnetic waves in a stable manner. A coaxial cable is used for providing R, G and B signals, a vertical synchronizing signal, and a horizontal synchronizing signal between the computer main body and the monitor. Flexible ribbon cable assemblies are widely used today within personal computers. Ribbon cables are flat, flexible cables containing a plurality of electrical wires that are aligned in a row. These cables are commonly used to establish a communication path between two computer devices, such as between a computer motherboard and a floppy disk drive. This is accomplished by using a ribbon cable connector, which is a connecting device that is attached to both ends of the cable. A standard ribbon cable connector includes a plurality of female slots that are arranged in the same predetermined pattern as the pins or teeth on the hardware device. The pin slots are sized to slidingly receive the pins on the hardware device. A user connects the ribbon cable to the hardware device by inserting the pins into the corresponding pin slots in the ribbon cable connector. Some types of computers have cable management devices, such as a cable management arm, that allow the various cables to be collected at the back of the computer server and rack for convenience and organization. Known cable management arms generally are devices that include two arm sections that are connected together at a hinged joint. Managing the position of a number of cables is typically carried out by cable clips, nylon cable ties or tape that position the cables adjacent to a computer frame. Reusable cable clips and nylon cable ties are used to fasten cables. Reusable cable clips generally hold one large diameter cable. Nylon cable ties are used to fasten or bundle several cables. Cable clips often allow several cables to be bundled together to facilitate better organization of the cables along a computer frame. Conduits have been used to arrange the cables.
A universal aerial bus (USB) cable is used to electrically connect a computer and other apparatuses. For example, input devices such as a mouse and a keyboard are connected through the USB cable to the computer. The universal serial bus (USB) is a serial bus standard that provides a method of coupling peripheral devices to a computer system. USB connections provide a flexible and adaptable method for connecting peripheral devices to computers. USB supports data exchange between a host computer and a wide range of simultaneously accessible devices which share USB bandwidth through a token scheduled protocol. The bus allows peripherals to be attached, configured, used, and detached while the host is in operation. The USB allows many devices to be daisy-chained with a single standard connector. The ability of USB devices to "plug and play" as well as the wide array of USB devices available make USB devices a common staple of computing accessories. USB peripherals may include keyboard, mouse, phone and answering machine, printer, scanner, fax/modem, ISDN, tablet, game controller, light pen, digital audio, and any other USB compliant device. The USB cable is a four wire cable, and the maximum cable length is about 5 meters. There are typically two connector types, and no cross-over cables and adapters are needed. USB cable lengths greater than about 5 meters may generate longer return times than the specified threshold value, and thus 5 meters is the maximum USB cable length. Five different types of plugs (male) or receptacles (female) are used on the ends of the USB cables to form these configurations. Any one of these plugs or receptacles may be found on either end of a USB cable. A USB connector is disposed at an end of the USB cable. The USB connector is inserted into a mount port disposed on a computer. When the USB connector is inserted into the mount port, a fastening claw in the USB connector is fastened to a fasten protrusion formed in the mount port, then the USB connector is fastened to the computer.
