Single Loop Cable Retention Hook

     The problem addressed by this invention is one of restraining or relieving a cable coming off a wall. In particular this pertains to the strain relief of power supply cables on the back of servers and the need to add cable restraint so that the action of the cable management arm does not pull the cable loose. Other considerations are that the invention needs to not impede airflow out the back of the unit, that the invention allow for the cable or power supply cord to be pulled out in an emergency, and that the invention fold flat for shipping (on the unit) when not in use.

     The invention is that of a wireform in such a design as to satisfy the above problem requirements. One such idea is that of a 'Single Loop Cable Retention Hook' similar in shape to a fishhook but mounted on the wall or bulkhead that the power supply cable exits from. The power cord would exit the back of the power supply and route through the 'hook' and thereby by restrained in motion alleviating the strain on the cord.

     Another idea is that of a 'Double Loop Cable Retention Hook' which has a lower portion similar in shape to the single loop fishhook. It also has an upper loop in which the power cord is made to go through first before the lower loop. The power cord would exit the back of the power supply and route through the 'upper loop' and then back around down through the 'hook' of the lower loop and thereby by restrained in motion alleviating the strain on the cord. The advantage of this design over the Single Loop Cable Retention Hook is that when the cable is routed through the upper hook the bend radius of the cable is not as severe as that of the single hook design also disclosed.

     For the single loop idea the invention mounts to the w...
