Abstract

With today's servers there can be as many five friction-retained cables (3 power, 1 mouse and 1 keyboard) connected to the rear of the unit. When a server is mounted in a rack, a cable management arm (CMA) is used to guide the cables from the back of the server to a vertical rail on the rear of the rack. Often, when the unit is rolled out on the guides for service, the cables which are not strain relieved (i.e. not screwed into the server) may become disconnected because the cables are too taught in the CMA. The disclosed invention is a single unit which addresses this problem. Slots in the plastic are designed in such a way as to accommodate a common range of diameters among these cables. After the cables are placed, the door is closed and latches into the finger clips. Split protrusions on the bottom of the unit are inserted into holes (existing) on the rear of the server. The pins are pressed through the entire unit and the protrusions flare to hold the unit in place. As stated, the unit uses friction from the press fit cables to strain relieve the cables. When the cables are inserted in the unit, they become 'pressed' into the slots so they can not slide in the slot relative to the unit. Previously, designers used five P-clips and screws to hold the cables. The new retention module is advantageous in that it requires no screws and thus no pierce and extrude holes. Being that there are no screws, assembly time is reduced. 1
