The present invention relates to electrical power strips and, more particularly, to the retention of power cord plugs plugged into electrical power strips.
Electrical power strips are utilized to distribute electrical power to various devices, such as desktop computers, servers, and rack systems. These electrical power strips generally have multiple outlets, which are engaged by the power cord plugs of the various devices.
Power cord plugs may inadvertently or unintentionally become disengaged from a power strip. Contributing to this problem is low mating forces between the power cord plug and the electrical power outlet of the power strip.
The present invention relates to an electrical power strip assembly for retaining power cord plugs. According to one aspect of the invention, an electrical power strip assembly is provided. The electrical power strip assembly includes electrical outlets for receiving power cord plugs. Strap mounts are also provided. Each strap mount includes a connection point associated with one of the electrical outlets. A housing defining a connection plane supports the electrical outlets in the connection plane and supports the strap mounts. Each strap mount connection point is proximal to the connection plane and to the electrical outlet associated with that strap mount connection point. Straps are coupled to the strap mounts to releasably secure a power cord plug received by one of the electrical outlets to the associated strap mount at the connection point.
According to another aspect of the invention, an electrical power strip is provided. The electrical power strip includes electrical outlets for receiving power cord plugs. Strap mounts are associated with respective electrical outlets. Each strap mount includes a connection point associated with one of the electrical outlets for receiving a strap to releasably secure a power cord plug received by the associated electrical outlet. A housing defining a connection plane supports the electrical outlets in the connection plane and supports the strap mounts. Each strap mount connection point is proximal to the connection plane and to the electrical outlet associated with that strap mount connection point.
The invention is best understood from the following detailed description when read in connection with the accompanying drawings, with like elements having the same reference numerals. When a plurality of similar elements are present, a single reference numeral may be assigned to the plurality of similar elements with a small letter designation referring to specific elements. When referring to the elements collectively or to a non-specific one or more of the elements, the small letter designation may be dropped. This emphasizes that according to common practice, the various features of the drawings are not drawn to scale. On the contrary, the dimensions of the various features are arbitrarily expanded or reduced for clarity. Included in the drawings are the following figures:
Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.
The power strip 14 includes multiple electrical outlets (represented by four electrical outlets 18a-d in the illustrated embodiment). The illustrated electrical outlets 18 each accept a single power cord plug 12. The straps 16 are configured to releasably secure a power cord plug 12 to one of the electrical outlets 18. It is to be understood that the power cord plugs 12 are not a component of the electrical power strip assembly 10.
The illustrated electrical power strip 14 includes a housing 15 having a substantially rectangular shape and a hollow interior for accommodating the electrical outlets 18 and associated circuitry, wires, and other hardware. Although four electrical outlets 18 are depicted, the electrical power strip 14 may include more or fewer electrical outlets 18. The electrical power strip 14 further includes a conventional power cord plug 19 that is electrically coupled to each electrical outlet 18 (electrical coupling not shown). The power cord plug 19 of the power strip 14 is adapted for insertion into a conventional electrical wall outlet (not shown) to provide electrical power to the electrical outlets 18.
The housing 15 supports multiple strap mounts (represented by four strap mounts 20a-d) in the illustrated embodiment. Straps 16 are mounted to the strap mounts 20 at connection points (represented by four connection points 21a-d). Each connection point 21 is associated with one of the electrical outlets 18. For example, connection point 21a is associated with electrical outlet 18a. In use, the straps 16 are wrapped around the power cord plugs 12 to retain the power cord plugs 12 in the electrical outlets 18 such that the power cord plugs 12 are prevented from being unintentionally or inadvertently disengaged from the electrical outlets 18.
The illustrated housing includes a flange 24 extending in a direction substantially orthogonal with respect to the connection plane 27. The flange 24 may be integral with the housing 15, or a separate component mounted to the housing 15, e.g., by a series of fasteners 17, as best shown in
The illustrated strap mounts 20 include apertures and, more particularly, rectangular slots 29 disposed along the flange 24. Each strap mount 20 accommodates a strap 16, as shown in
A strap 16 is mounted to the strap mount 20 at the connection point 21 of that strap mount 20. Each strap mount connection point 21 is associated with one of the plurality of electrical outlets 18. More particularly, and according to one aspect of the invention, adjacent electrical outlets 18 are separated by a predetermined distance “X” along the longitudinal axis “L” of the housing 15. Adjacent strap mounts 20 are also separated by the same predetermined distance “X.” Each strap mount 20 is substantially aligned with an electrical outlet 18 along the longitudinal axis “L” of the housing 15. By aligning each strap mount 20 with an electrical outlet 18, each strap mount connection point 21 is associated with one of the plurality of electrical outlets 18.
Each strap mount connection point 21 is positioned proximal to the connection plane 26 and proximal to the electrical outlet 18 associated with that strap mount connection point. In an exemplary embodiment utilizing slots 29 (as best shown in
Furthermore, the electrical outlets 18 are arranged along a longitudinal axis “L” of the housing 15 and the connection points 21 of the strap mounts 20 are arranged along a mounting axis “M” that is parallel to the longitudinal axis “L.” The mounting axis “M” is separated from the longitudinal axis “L” by a dimension “E” that includes at least one directional component that is parallel to the connection plane 26. By maintaining the parallel component of dimension “E” as small as possible, but large enough to accommodate a power cord plug 12, and minimizing any perpendicular component, each strap mount connection point is positioned proximal to its associated electrical power outlet 18.
The strap 16 includes a mounting portion 28, in the form of a loop, for mounting to a strap mount 20 of the power strip 14 at a connection point, and an extended portion 30 for releasably securing a power cord plug 12. An aperture 32 is formed in the mounting portion 28 of the strap. The height dimension “H1” of the mounting portion 28 of the strap 16 is greater than the height dimension “H2” of the extended portion 30 to accommodate the height of the aperture 32.
In use, the extended portion 30 is inserted through the slot 29 of the power strip 14. The extended portion 30 is then inserted through the aperture 32 of the strap 16 thereby forming a loop around the slot 29. The extended portion 30 of the strap 16 is then wrapped around a power cord plug 12 and releasably fastened to itself, thereby securing the power cord plug 12 to the power strip 14, as best shown in
According to the exemplary embodiment shown in
The mounting portion 28 of the strap 16 is not limited to a loop. By way of non-limiting example, the mounting portion 28 may comprise a button, a connector, a releasable adhesive, a fastener, an aperture, a snap, a plug, hook material, loop material, or any other means for fastening known in the art, so long as the mounting portion 28 is engageable with the strap mount 20 of the power strip 14.
The strap 16 and strap mount 20 arrangement disclosed herein possesses several benefits over prior art power cord retention solutions for power strips 14. Unlike the prior art power cord retention solutions that are intended for use with an often non-conventional single power cord plug style, the strap 16 described herein may be fastened around any conventional or non-conventional power cord plug.
While exemplary embodiments of the invention have been shown and described herein, it will be understood that such embodiments are provided by way of example only. Numerous variations, changes and substitutions will occur to those skilled in the art without departing from the spirit of the invention.
