[0011] Referring to FIG. 2, an apparatus 100 for retaining a plug in a receptacle is shown with retention device 120 inserted within receptacle body 1 10. It is contemplated that retention device 120 may be inserted within the receptacle body 1 10 and may retain a plug with a shroud without requiring any modification to the shroud.
[0012] Referring to FIGS. 3-5, a retention device 120 in accordance with various embodiments of the present disclosure is shown. It is contemplated the retention device 120 may be operable with at least one prong 124B as shown in FIG. 5. In alternative embodiments, retention device 120 may include three prongs (124A-124C) and four prongs (124A- 124D) as shown in FIG. 4 and FIG. 3 respectively. Additionally, retention device 120 may include two prongs or may include five or more prongs without departing from the scope and intent of the present disclosure. It is further contemplated that the placement of the at least one prong may be adjusted without departing from the scope and intent of the present disclosure. As shown in FIG. 3, four prongs 124A-124D may be placed to make contact with corners of a shroud 220 of plug 200 as shown in FIG. 6. However, it should be understood that prongs 124A-124D may be placed to make contact with sides of shroud 220 of plug 200 as shown in FIG. 6. Similarly, placement of the at least one prong may be placed in alternate locations to make contact with one or more corners and one or more sides of a shroud 220 of plug 200 as shown in FIG. 6.
[0013] Each prong 124A-124D may include at least one barb 128 and a ridge 130. Barb 128 may refer to a projection extending from the prong which is configured to contact a shroud of a plug. It is contemplated that barb 128 may be formed of metal, such as stainless steel, and may project from the prong which may be formed of plastic. It is contemplated that barb 128 may project from the prong at a desired angle in order to enhance the retention of the plug. As shown in FIG. 3, in one embodiment, each barb extends from each prong at an angle, Θ, of about 120-150 degrees from the prong as the prong extends from the face portion 122 of the retention device 120. The desired angle of about 120- 150 degrees from the prong as the prong extends from the face portion 122 of the retention device 120 may apply to one or more barbs of one or more prongs of the retention device 120.
[0014] Referring to FIG. 6, an exemplary plug 200 which is retained in the retaining apparatus in accordance with an embodiment of the present disclosure is shown. Plug 200 may include a male electrical fitting for making an electrical connection with a corresponding female fitting, such as receptacle 1 14. It is contemplated that plug 200 may be electrically coupled with cable 230. Plug 200 may include a shroud 220. In an alternative embodiment, plug 200 may include a female electrical fitting for making an electrical connection with a corresponding male fitting, such as an inlet mechanism as shown and described in FIG. 9 and a connector as shown and described in FIG. 10.
[0015] Referring to FIG. 7 and FIG. 8, cutaway views of the apparatus for retaining a plug are shown. FIG. 7 depicts a cutaway view of the apparatus for retaining a plug in a receptacle in a retention position in accordance with an embodiment of the present disclosure. FIG. 8 depicts a cutaway view of the apparatus for retaining a plug in a receptacle in a release position in accordance with an embodiment of the present disclosure.
[0016] As shown in FIG. 7, barb 128 of each prong of a plurality of prongs contact shroud 220. Each prong is forced toward the shroud 220 by contact from a second side or exterior side of the prong by tapered wall portion 136 of the receptacle body 1 10. As can be seen, the tapered wall portion 136 puts more force on each prong as the plug is pulled from the receptacle body 120 while still remaining in electrical contact with the receptacle. The tapered wall portion 136, or ramp, reduces the space in the receptacle body as the plug is removed from the body. This causes more force to be applied to each prong of the retention device and causes each barb of each prong to make contact with the shroud. The plug may be jammed between the prongs of the retention device and retained within the receptacle body, also referred as an interference fit or contact fit.
[0017] Receptacle body 1 10 further includes a ledge 134 configured to prevent removal of retention device 120 from the receptacle body 1 10 by contacting ridge 130 of each prong of the retention device 120. When plug 200 should be removed from apparatus for retaining the plug, face portion 122 of retention device 120 is forced inward toward the receptacle body 1 10. By forcing the retention device 120 toward the receptacle body 1 10, the jam caused by the prongs of the retention device 120 may be released. As the retention device 120 is forced toward the receptacle body 1 10, the space within the receptacle body expands as tapered wall portion 136 of the receptacle body 1 10 may be tapered toward the interior of the receptacle body 1 10. When this occurs, there is less force applied to each prong by the tapered wall portion 136 of receptacle body 1 10. As a result, each barb 128 of each prong of the retention device 120 releases the shroud 220 of the plug 200.
[0018] Referring to FIG. 9 and FIG. 10, an apparatus 305 for retaining a connector 260 in an inlet mechanism 250 in accordance with an embodiment of the present disclosure is shown. Inlet mechanism 250 may include a male electrical fitting and may be similar as receptacle 1 10 but may include the male pins. Retention device 120 may operate with inlet mechanism 250 to retain a corresponding female electrical fitting such as connector 260 as shown in FIG. 10. It is contemplated that a barb of at least one prong of retention device 120 may contact and retain a shroud of connector 260. In an embodiment, retention device 120 and inlet mechanism 250 may include a retention position and release position as described and shown in FIG. 7 and FIG. 8 with respect to a receptacle body 1 10. [0019] Referring to FIG. 1 1 , a power strip 300 including an apparatus for retaining a plug in a receptacle in accordance with an embodiment of the present disclosure is shown. Power strip 300 may include a plurality of receptacles 1 14 which supply power to a plurality of electronic devices. It is contemplated that multiple apparatuses 100 for retaining a plug may be employed in a power strip 300 to prevent unintended disconnection of a plug from a receptacle. It is contemplated that face portion of retention device 120 may include one or more tabs 310. One or more tabs 310 may allow easier finger access to the retention device to allow the retention device to be forced toward the receptacle body to allow removal of a plug.
[0020] Referring to FIG. 12, a power strip 320 may include an apparatus 100 for retaining a plug in a receptacle and an apparatus 305 for retaining a connector in an inlet mechanism in accordance with an embodiment of the present disclosure is shown. It is contemplated that multiple apparatuses 100, 305 may be employed in a power strip 320 to prevent unintended disconnection of a plug or connector. It is contemplated that face portion of retention device 120 may include one or more tabs 310. One or more tabs 310 may allow easier finger access to the retention device to allow the retention device to be forced toward the receptacle body to allow removal of a plug.
[0021] It is contemplated that apparatus 100, 305 may provide a number of advantages over locking receptacles known to the conventional art. Conventional locking receptacles may include specialized receptacles or specialized plugs. Specialized receptacles and specialized plugs create additional costs and reduce the flexibility to change power cords in a large scale electrical power distribution system, such as power strips employed in a data center providing power to multiple data servers. Advantageously, apparatus 100, 305 may be operable with power cords supplied by the manufacturers of electronic equipment, such as data servers. [0022] It is contemplated that apparatus 100, 305 may be operable with IEC 60320 couplers, referring to a list of standards from the International Electrotechnical Commission specifying non-locking appliance couplers and interconnection couplers for the connection of power supply cords to electrical appliances up to 250 Volts, including C13, C15, C19 and C21 receptacles. Additionally, it is contemplated that apparatus 100 may be operable with any type of plug that includes a shroud that may cover at least a portion of the pins of the plug. Also, the apparatus 305 may be operable with a female coupler with any type of shroud.
[0023] An additional advantage of the apparatus 100, 305 may include the ability to employ labels and different colors. By adding an identifier such as color or a label to the face portion 122 of the retention device 120, particular receptacles may be more easily identified and separated, particularly when implemented with a power strip 300, 320 as depicted in FIG. 1 1 and FIG. 12.
[0024] It is believed that the present disclosure and many of its attendant advantages will be understood by the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the components without departing from the disclosed subject matter or without sacrificing all of its material advantages. The form described is merely explanatory, and it is the intention of the following claims to encompass and include such changes.
