DESC:The present disclosure will now be described with reference to the accompanying drawings wherein the same numerals are used to denote the same part. However, the drawings only illustrate the disclosure and in no way limit the disclosure.

The terms and words used in the following description and claims are not limited to the bibliographical meanings but are merely used by the inventor to enable a clear and consistent understanding of the disclosure. The description given herein is only representative of the illustrative embodiments and examples. Only for the sake of convenience, the description has focused on a limited number of representative examples of the drawings. However, the drawings and/or illustrations in no way limit the scope of the disclosure. It is understood that modifications and/or alterations of the drawings/illustrations of this disclosure other than those specifically set forth herein may be achieved by those skilled in the art and that such modifications and alterations are to be considered as falling within the overall scope of this disclosure.

Terms used herein are used only in order to describe an exemplary embodiment rather than limiting the present disclosure. In this case, singular forms include plural forms unless interpreted otherwise in context.

A high current electrical outlet and plug disclosed herein facilitates the high current connectivity by way of a simplified and space saving compact solution by providing adequate creepage distances between the conductive contacts. The high current connectivity is possible by using a set of conductive contacts of unique profile by which the physical contact area between the forks of conductive contacts of outlet and the conductive pins of mating plug is greater. The shape and size of the high current outlet of the present disclosure is similar to 16 Amp rated IEC-60320 C-21; however, the non-conductive housing of the outlet is modified to prevent use of standard C-20 electrical plug. Referring to Figure 5, 6 and 7, the high current electrical outlet (50) comprises a nonconductive housing (50A) similar to IEC-60320 C-21 and a set of conductive contacts (50B). As detailed in Figure 8, the non-conductive housing (50A) of the high current electrical outlet (50) is profiled with a central projecting core (50A2) which accommodates the conductive contacts (50B). A set of three pockets (50A4) is disposed on the central projecting core (50A2) for the entry of conductive contact pins (60B), (60C) of the mating plug (60) to establish the connection. The peripheral shroud (50A1) surrounds the central projecting core (50A2) where cantilever snaps (50A5) are disposed on at least two sides of the housing (50A). A pair of projections (50A3) are profiled out of the central projecting core (50A2) to prevent the entry of any conventional electrical plugs.
The conductive contacts (50B) are profiled with a top portion (50B1) formed like inverted V-shape which deflect elastically towards outward directions and revert to nearly original shape while the contacts (50B) are inserted and pressed inside the pockets (50A4) of the non-conductive housing (50A). The middle portion (50B2) of the conductive contact (50B) is flat on either arm which assists for stability of contact inside the pocket (50A4) of non-conductive housing (50A). The bottom portion (50B3) is a combination of V and inverted V shape generated by a converging profile (50B4) and a diverging profile (50B5) on the fork arms which creates a connecting face (50B6) at the interface of the V and inverted V. The connecting face (50B6) is the connecting face between the conductive parts of the outlet (50) and the plug (60) and this is the portion of the fork arm which generates a retention force between the two when coupled. Further, an additional connecting face (50B9) is formed in the middle portion (50B2) with a combination of V and inverted V shape generated by a converging profile (50B7) and a diverging profile (50B8). This unique arrangement ensures high current conductivity since the conductive pins (60B) and (60C) of the mating plug (60) physically touch at two faces (50B6) and (50B9) thereby adding higher surface area of contact. The higher surface area supports better electrical conductivity which is necessary for higher current connectivity.
The mating plug (60) is profiled with a non-conductive housing (60A) and a set of conductive contact pins (60B) and (60C) therein. Slots (60A1) are disposed inside either side of the shroud wall of the non-conductive housing (60A). The projections (50A3) of the non-conductive housing (50A) of the high current outlet (50) fit into the slots (60A1) of the mating plug (60) to ensure that the high current electrical outlet (50) can mate only with the corresponding plug (60) of the present disclosure. Therefore, other conventional low current plugs cannot be coupled with it.

Figure 9 shows the top view of the high current electrical outlet (50) showing the non-conductive housing (50A), the shroud (50A1), the central projecting core (50A2), the projections (50A3) and the pockets (50A4).

Figure 10 shows the conductive pin (60B) of the mating plug (60) inserted into the contact (50B) such that conductive pins (60B) and (60C) of the mating plug (60) physically touch at two faces (50B6) and (50B9).

Figure 11 shows the top view of the mating plug (60) showing the shroud wall of the non-conductive housing (60A), the slots (60A1) and the conductive pins (60B) and (60C).

In an alternate embodiment of the present disclosure as shown in Figure 12, 13 and 14, a high current outlet (70) has pin entry pockets (70A4) oriented vertically.

Figure 13 shows the conductive contacts (50B) as per original embodiment detailed above and the nonconductive housing as per alternate embodiment (70).

A mating plug (80) as disclosed in Figure 14 can be coupled with the outlet (70) as the conductive pins (80B and 80C) of plug (80) are located vertically to suit the entry pockets (70A4) of the electrical outlet (70).
Further, various child parts of mating plug (80) namely a non-conductive housing (80A), a holding strip (80C), a cable grommet (80D) and screw fitments (80E), (80G) are shown in the exploded view as per Figure 15. A set of conductive pins (80B and 80C) are placed inside the nonconductive housing (80A). The cable holding strip (80C) and cable grommet (80D) act as a strain relief to the cable.

In another embodiment a high current outlet (100) having pin entry pockets (100A4) oriented vertically is disclosed as shown in Figure 16, 17 and 18 which offers a lockable fitment (100A6) to lock the mating plug (80). The cantilever locking arm (100A7) is integrally formed with the non-conductive housing (100A) of the outlet (100). The said arm has a projection (100A8) and locking tip (100A9). The locking tip (100A9) latches with the peripheral step on the outer face of the surrounding shroud of the non-conductive housing (80A). It offers protection against unwanted extraction of the plug from outlet. The projection (100A8) acts as a handle for actuation of the arm for locking and unlocking purposes.
