Good cable management also makes working inside a computer much easier by providing safer hardware installation, repair, or removal. The organized routing of cables inside the computer case allows for optimal airflow and cooling. Power cables often need to be grouped separately and suitably apart from data cables, and only cross at right angles which minimizes electromagnetic interference. Some cables have requirements for minimum bending radius or proximity to other cables, particularly power cables, to avoid crosstalk or interference. The cable management needs at either end are different.īuildings and office furniture are often designed with cable management in mind for instance, desks sometimes have holes to pass cables, and dropped ceilings, raised floors and in-floor cellular raceway systems provide easy access. The other end of a cable ends at the desk. Generally, one end of a cable is terminated in the data cabinet. Strain relief components are also used in applications where cables, conduits and hoses are exposed to constant dynamic stress ( cable carriers / drag chains).Ĭomputer data cabling, structured cabling, LAN cabling For PROFINET, for example, which is used in automation it is recommended to set the strain relief component approx. At which point the lines have to be strain relieved depends on the application. Strain relief is often required for terminated electrical lines that are plugged into sockets or ports to prevent unplugging or accidentally ripping out of the connector. Strain relief plates are therefore a more flexible solution which allows a parallel routing of several lines with varying diameters. The installation of the single cable clamps can take a lot of mounting time, depending on the laying length of the lines. That causes higher acquisition and storage costs. In case of industrial applications these strain relief plates are also cost-effective because the packing density (meaning the possible number of lines to be fixed on one plate) is much higher than with common cable clamps which are normally designed for holding one single line.įurthermore, most of the available cable clamps are not very flexible when it comes to routing lines with varying diameters. Ī more cable-friendly alternative is attaching the lines to special strain relief plates using common cable ties. Another possibility is to use so called cord grips which consist of weaved wire strands that put a grip around the cables. Usually, the lines are fixed by clamping them into single cable clamps made of plastic or metal. With a strain relief component, the connection between a flexible electrical line and its connection port is protected against mechanical stress. It is regulated by the European standard EN 62444 (formerly EN 50262. Strain relief plate on the end of a cable carrierĬable strain relief is a mechanical protection for flexible electrical cables, wires, conduits and pneumatic hoses.

Planning is especially crucial for cables such as Thicknet that do not bend around corners easily and fiber optic which is very difficult to splice once cut. Above drop ceilings, hooks or trays are used to organize cables and protect them from electrical interference Documenting and labeling cable runs, tying related cables together by cable ties, cable lacing, rubber bands or other means, running them through cable guides, and clipping or stapling them to walls are other common methods of keeping them organized. For instance, the wires coming out of ATX power supplies are color-coded by voltage. The choice of cables is also important for instance, ribbon cables used to connect Parallel ATA drives to the motherboard can disrupt the airflow inside of computers, making case fans less effective most SATA cables are more compact and therefore do not have this problem.Ĭolor-coding of cables is sometimes used to keep track of which is which. 4 Computer data cabling, structured cabling, LAN cabling.JSTOR ( November 2017) ( Learn how and when to remove this template message).Unsourced material may be challenged and removed.
