Abstract

The proposed invention provides connector strain relief for portable electronic devices such as laptop computers. To that end, the proposed invention calls for an appropriately dimensioned diagonal slot--milled or molded-- in the lower edge of the device chassis (external case, shell, body), located immediately below each standard female connector. Once the cord is connected to the device, the cord can then be quickly squeezed snugly into its respective, appropriately dimensioned slot, so that a continuous surface is formed, flush with the lower edge of the laptop. The fixed, manufactured dimension of the slot, specific to the standard dimensions of each power or data cord used, assures a snug, reliable fit. Appropriate dimensioning of the slot also permits easy removal by the user whenever desired. Actual strain relief is provided by a slight loop of cord that is allowed to form as a buffer between each connector and its respective strain-relief slot. This loop must be sufficiently large so as to not inadvertently introduce the very strain on the mating connectors, that it is intended to prevent.

Problem:

[circle6]Power and data cord connected to laptop computers and other portable electronic devices typically feature little strain-relief protection, leaving connectors vulnerable to damage, faulty connections and disconnection.

Solution:

[circle6]Proposed invention calls for an appropriately dimensioned diagonal slot - milled or molded - in the lower edge of the device chasis (external case, shell, body), just below each female connector. [circle6]Once the cord is connected to the device, the cord can then be quickly squeezed snugly into its respective, appropriately dimensioned slot, so that a continuous surface is formed, flush with the lower edge of the laptop . [circle6]The fixed, manufactured dimension of the slot, specific to each of the power or data cord dimensions used, assures a snug reliable fit. [circle6]Appropriate dimensioning of the slot also permits easy removal by the user whenever desired. [circle6]Actual strain relief is provided by a slight loop of cord that is allowed to form as a buffer between each connector and its repective strain-relief slot. This loop must be sufficiently large so as to not inadvertently introduce the very strain, that is intended to prevent.
