Definitions

  • Connectors typically include prong type terminals, generally referred to as plugs, and female connectors designed for receiving the prong type terminals, generally referred to as receptacles, often described as electrical outlets, or simply outlets.
  • the most common types of outlets include a pair of terminal contacts that receive the prongs of a plug that are coupled to "hot” and "neutral" conductors. Further, outlets include a terminal contact that receives a ground prong of a plug.
  • the design of aforementioned plug and receptacle system generally incorporates a friction only means of securing the two in the mated position.
  • the frictional coefficient varies depending on a variety of conditions, including, but not limited to, manufacturing processes, foreign materials acting as lubricants, and wear and distortion of the assemblies. This characteristic results in a non-secure means of interconnecting AC power between two devices. It is arguably the weakest link in the power delivery system to electrical or electronic devices utilizing the system. However, it has been adopted worldwide as a standard, and is used primarily due to low cost of manufacture, ease of quality control during manufacture, and efficient use of space for the power delivery it is intended to perform.
  • connection technique simply the friction fit component.
  • a technique to secure the mated connection may be desirable to improve the reliability. This may especially be true in mechanically active locations, such as where vibration is present, or where external activity may cause the cords attached to the plugs and receptacles to be mechanically deflected or strained in any manner.
  • GB 2 383 202 A discloses a locking electrical connector comprising a socket for receiving a plug having a plurality of pins, wherein the socket presents a greater resistance to withdrawal of at least one pin than to insertion of the pin. It does not disclose a release element extending from said a first front surface of a first housing portion at a location spaced from said opening such that said release element is accessible by a user when said male and female assemblies are in a connected state.
  • US 6 533 598 B1 discloses a lockable wall outlet electrical receptacle having a housing with a pair of vertically spaced electrical plug aperture set formed in its front wall surface.
  • US 4 586 770 A discloses an electrical receptacle comprising a housing having apertures for receiving blade-type contacts of a plug in which the plug is formed with an aperture at its free end, and a pair of contacts secured in the interior of the housing in longitudinal alignment with the apertures for electrically conductively contacting plug contacts inserted through the apertures, each contact member having a flexible contact portion having a projection releasably interlockable with the aperture of a plug contact to prevent inadvertent withdrawal of the plug contacts from the housing and an arrangement for selectively manually displacing the contact portions for releasing the plug contacts.
  • the present invention is directed to securing an electrical connection.
  • mating plug and socket electrical connections may be the least secure link in the power delivery system.
  • these connections are secured only by means of a friction fit. A number of factors may affect the security of this connection.
  • the present invention provides a clamping mechanism whereby the very forces that would otherwise tend to pull the connection apart serve to actuate the clamping mechanism thereby securing the mated pair.
  • the invention is of simple construction and highly reliable in operation. Moreover, the invention can be implemented simply in connection with new or retrofitted receptacle devices. Thus, the system is compatible with existing plugs and other infrastructure.
  • an apparatus according to claim 1 is provided for use in securing an electrical connection.
  • a method according to claim 4 for using a securing device is provided.
  • Figures 1A-1C illustrate the operation of an embodiment of a clamping mechanism for securing a mated electrical connection that may be included in a locking receptacle of the present invention.
  • the bottom portion represents a side view of a prong 16 and a clamping mechanism 12, while the top portion represents a perspective view.
  • the prong 16 of a plug is shown prior to insertion into a receptacle 10.
  • the prong 16 is a ground prong, may be of a standard plug (e.g., an IEC 320 plug, a NEMA 5-15, or the like) and may be various sizes and shapes.
  • the receptacle 10 may be the ground receptacle of a standard outlet (e.g., a NEMA standard cord cap, an IEC 320 cord cap, or the like) that is operative to receive a standard plug.
  • the receptacle 10 also includes the clamping mechanism 12 that is coupled to a pivot 14.
  • the clamping mechanism 12 includes an aperture that is sized to be slightly larger than the prong 16, such that the prong 16 may only pass through the aperture when the length of the clamping mechanism is substantially perpendicular to the length of the prong 16. That is, the design of the clamping mechanism 12 is such that a simple slide on and capture technique is utilized.
  • Figure 1B illustrates the prong 16 when inserted into the receptacle 10.
  • the prong 16 passes through the aperture in the clamping mechanism 12 and into the receptacle 10, such that the corresponding plug and outlet are in a mated position.
  • the clamping mechanism 12 further may include a stop (not shown) to prevent the clamping mechanism 12 from pivoting during the insertion of the prong 16.
  • the length of the clamping mechanism 12 will remain substantially perpendicular to the length of the prong 16, which permits the passage of the prong through the aperture of the clamping mechanism 12.
  • Figure 1C illustrates the gripping function of the clamping mechanism 12 in reaction to a force on the prong 16 that tends to withdrawal the prong 16 from the receptacle 10.
  • the clamping mechanism 12 In reaction to a withdrawal of the prong 16, the clamping mechanism 12 angularly deflects (i.e., rotates) about the pivot 14, causing the aperture in the clamping mechanism 12 to grip the prongs 16.
  • the very force that tends to withdraw the prong 16 from the receptacle acts to actuate the clamping mechanism 12 to engage the prong 16, thereby preventing the withdrawal of the prong 16, and maintaining the electrical connection of the mated assembly.
  • the clamping mechanism 12 may be constructed of any suitable material, including a high strength dielectric with an imbedded metallic gripping tooth. An all-metallic clamping mechanism may also be used since the prong 16 is a ground prong.
  • Figures 2A-2B illustrate a cross section of one embodiment of a locking electrical receptacle 20 not forming part of the invention.
  • the receptacle 20 is an IEC type 320 cord cap receptacle that includes a locking mechanism.
  • the receptacle 20 includes an inner contact carrier module 24 that houses contact sockets 26 and 28. Attached to the contact sockets are wires 36 and 38 that extend out of the receptacle 20 though a cord 34.
  • the carrier module 24 may be attached to a cord strain relief 32 that functions to prevent the breaking of the electrical connections when a force is applied to the cord 34.
  • a spring prong retainer 40 is disposed adjacent to a surface of the carrier module 24, and extends across a prong-receiving portion 44 of the receptacle 20. One end of the spring prong retainer 40 bent around the end of the inner contact carrier module 24, which secures it in the assembly.
  • the spring prong retainer 40 includes an aperture sized to permit the passage of the ground prong of a plug into the socket 26.
  • the aperture in the spring prong retainer 40 may be sized to be slightly larger than one prong (e.g., the ground prong) in a standard plug such that the aperture may function as the clamping mechanism for the locking receptacle 20.
  • the operation of the clamping feature of the spring prong retainer 40 is discussed in detail below.
  • Figure 2A illustrates the locking receptacle 20 when there is little or no strain on the cord 34.
  • the portion of the spring prong retainer 40 disposed in the prong-receiving portion 44 of the receptacle 20 is not in a substantially vertical position.
  • the apertures of the spring prong retainer 40 in this configuration will allow the prongs of a plug to pass freely into the socket 26 when the prong is inserted. This is due to the unrestricted change of position of the spring prong retainer 40 to the substantially vertical position as the prongs of a plug acts upon it.
  • Figure 2B illustrates the locking receptacle 20 when a force is applied to the cord 34 of the receptacle 20 in the opposite direction of the grip release handle 30. This is the "release position" of the receptacle 20 and is shown without the mating prongs for clarity of operation. Actions that initiate this position are illustrated in Figures 3A and 3B .
  • FIG 3A illustrates the operation of the locking electrical receptacle 20 shown in Figures 2A-2B .
  • a prong 54 of a plug 50 When a prong 54 of a plug 50 first enters the receptacle 20 via an aperture in the lock release grip 22, it encounters the spring prong retainer 40, which is not in the perpendicular orientation at that time. Upon additional insertion, the spring prong retainer 40 is deflected into the perpendicular position by the force applied to it by the prong 54. The prong 54 passes through the aperture in the spring prong retainer 40 and into the contact socket 26, making the electrical connection as required. Upon release of the insertion force, and when no axial strain is applied to the mated plug 50 and receptacle 20, the spring prong retainer 40 is only partially displaced from the perpendicular axis.
  • Figure 3B illustrates in an exaggerated manner the condition of applying axial tension to the cord 34 of the receptacle 20.
  • the slight retraction motion pulls on the spring prong retainer 40, thereby increasing the angle of grip and subsequent tightening of the offset angle of the spring prong retainer 40 and prong 54.
  • the receptacle 20 and the plug 50 are then fully locked in this condition.
  • the position of the spring prong retainer 40 is returned to the near-perpendicular position as illustrated in Figure 3A , thereby releasing the spring prong retainer 40 from the prong 54.
  • the receptacle 20 is easily separated from the plug 50.
  • the safety of the receptacle 20 may be greatly improved.
  • the effect of the application of various electrical potentials to clamping mechanism of the assembly is avoided, which may simplify the manufacturing of the receptacle, as well as improve its overall safety.
  • Figures 4A-4C illustrate a locking device 60 not forming part of the invention for providing a locking feature for a standard receptacle.
  • the locking device 60 includes a top holding member 62 and a bottom holding member 64 for positioning the locking device 60 onto a standard receptacle.
  • the locking device 60 also includes a portion 66 that couples the holding member 62, 64 in relation to each other to provide a secure attachment to a receptacle.
  • the locking device 60 also includes a clamping mechanism 68 that is coupled to a pivot 70. The operation of the clamping mechanism 68 is similar to that of the clamping mechanism 12 illustrated in figures 1A-1C .
  • the locking device 60 may also include a release mechanism 72 that is operative to enable a user to disengage the clamping mechanism 68 when it is desired to remove a receptacle from a plug.
  • Figure 4B illustrates the locking device 60 positioned on to a standard receptacle 80.
  • the holding members 62 and 64 may be made of an elastic material such that a user may bend them outward and position the device 60 onto the receptacle 80.
  • the holding members 62, 64 may be made of plastic.
  • the holding members 62, 64 are shaped such that once installed onto the receptacle 80, the device 60 is not easily removed without a user deforming the holding members 62, 64. That is, the holding members 62, 64 may be shaped to closely fit onto standard receptacle, such that normal movements will not disengage the device 60 from the plug 80.
  • Figure 4C illustrates the operation of the locking device 60 when the receptacle 80 is mated with a standard plug 84.
  • the ground prong 86 of the plug 84 passes through an aperture in the clamping mechanism 68 and into the receptacle 80. If a withdrawing force tending to break the mated connection is applied to either the cord of the standard plug 84 or the cord of the receptacle 80, the clamping mechanism 68 will rotate, causing it to grip the ground to prong of the standard plug 84, thereby maintaining the electrical connection.
  • a locking device 60 may be engaged to release element 72, which is operative to maintain the clamping mechanism 68 in a substantially perpendicular position relative to the ground prong 86, thereby permitting the prong 86 of the standard plug 84 to be withdrawn from the receptacle 80. It should be appreciated that although one particular embodiment of a locking device 60 has been illustrated, there may be a variety of ways to implement a locking device that may be retrofitted to a standard receptacle that uses the techniques of the present invention.
  • FIG. 5 illustrates an embodiment according to the present invention of a standard duplex locking receptacle 100
  • clamping mechanisms 112 and 114 are integrated into the receptacle 100.
  • the top portion of the receptacle 100 includes sockets 102, 104 for receiving the prongs 128, 130, respectively, of a standard plug 126.
  • the bottom portion of the receptacle 100 includes sockets 106, 108 for receiving a second standard plug.
  • the clamping mechanisms 112, 114 are each pivotable about the pivots 116, 118 respectively.
  • the receptacle 100 also includes release elements 120, 122 that are operative to permit a user to break the connection when desired.
  • the operation of the clamping mechanism 112, 114 is similar to that in previously described embodiments.
  • the clamping mechanism 112 rotates in the direction of the plug 126, and engages the ground prong 130, preventing the mated connection from being broken. If a user desires to intentionally remove the plug 126 from the receptacle 100, the user may activate the release mechanism 120 and withdraw the plug 126.
  • Figures 6A-6B illustrate side views of a receptacle 150 not forming part of the invention that includes a cam lock 152 for locking the prong 162 of a plug 160 to preserve a mated connection between the receptacle 150 and the plug 160.
  • Figure 6A illustrates the receptacle prior to the insertion of the plug 160, and the cam lock 152 may hang freely from a pivot 153.
  • an end of the cam lock 152 is positioned in the opening of the receptacle 150 that is adapted for receiving the prong 162 of the plug 160.
  • Figure 6B illustrates the mated connection of the plug 160 and the receptacle 150.
  • the prong 162 has deflected the cam lock 152 about the pivot 153, causing the cam lock 152 to be angled away from the plug 160 and abutted with the prong 162.
  • the friction between the cam lock 152 and the prong 162 will tend to force the cam lock 152 downward toward the prong 162, which functions to retain the plug 160 in its mated position.
  • a user desires to intentionally remove the plug 160 from the receptacle 150, they may press the actuating mechanism 154, which may be operable to rotate the cam lock 152 out of the way of the prong 162, thereby enabling the user to freely withdraw the plug 160 from the receptacle 150.
