Abstract

A cable retention mechanism includes (1) a clip-like device with spring-gates, and (2) a bracket or a product feature that provides attachment points for the clip-like device(s). The mechanism can be implemented on power distribution units (PDUs), Electronic Industries Alliance (EIA) locations in racks, power suppliy units (PSUs), or other connectors on machines to prevent power cords or cables from being loosened or unplugged by inadvertent force.

Power cord retention mechanism

Machines' power cords or cables can be accidentally unplugged from the power distribution units (PDUs) or the connectors on machines, for example the power supply units (PSUs). Without a

proper mechanism to retain the cords or cables, any inadvertent force (when routing cables, servicing machine components, etc.) may loosen or even detach the cords or cables from their connectors, which can seriously affect the operations of machines.

For solving this problem, there have been a few solutions proposed in the market or patented. However, they have two main drawbacks: First, they are only compatible to specific designs of

products. For users, nevertheless, if a solution can not be compatible to their current racks, machines, and PDUs, the willingness to adopt and purchase the solution would be very limited. Second, the current solutions are useful, but not necessarily very usable. They have the capabilities to retain power cords or cables, but they are not easy for users to do quick installations, un-installations, and adjustments.

The disclosed invention is a mechanism that is useful and usable to retain power cords or cables. The mechanism can be implemented on PDUs, on EIA locations in racks, PSUs, or other connectors on machines to prevent power cords or cables from being loosened or unplugged by inadvertent force. The mechanism includes two parts: (1) a clip-like device with spring-gates, and (2) a bracket or a product feature that provides attachment points for the clip-like device(s) (Figure 1). The attachment point of the clip will be away from the center line of the connector to optimize the retention function. When any inadvertent force is applied to a power cord or cable, it will be transferred to the cable retention mechanism instead of the connector directly.

The invention has four main advantages. First, it is useful and low-cost. Second, it can be applied to the majority of current products in the market. Third, the use of the cable retention mechanism will not affect the operations of running machines. Users do not need to shut down machines and disconnect the cables during the installations, un-installations, and servicing. Lastly, the invention is not only useful but also very usable. The installations, un-installations, and adjustments of the cable...
