In the superincumbent execution mode, kettle 1 comprises two independent heating element 8a and 8b.In alternative, kettle 1 can comprise single heating element.For example, in Britain, the rated value of single heating element can reach 6kW, and is arranged to draw power from two power outlets or socket.In this less preferred alternative, must comprise the interlocking (not shown) in multi-cable plug 10 or the kettle 1, unless thereby provide power from two power outlets or socket, otherwise kettle 1 will be can not operate to avoid single power outlet or socket overload, perhaps make not the socket that connects charged.

Top execution mode and alternative provide the kettle of the maximum power application with increase, but feature of the present invention is applicatory to other household electrical appliance, and be favourable to high-power household electrical appliance especially, for example air-conditioning, electric heater, water heater are such as owing heat radiation (under-sink) or crossing heat radiation (over-sink) heater, display, portable or interim display, jet washing machine, Jacuzzi (Jacuzzi), sauna, immersion heater and kitchen range of heating.

The present invention is preferably helping intermittently use and is therefore implementing in the electrical equipment that the maximum power place can't operate with the time of an elongated segment, for example kettle, food blender, drink manufacturing electrical equipment, cooking appliance, electric tool, garden furniture etc.The present invention also is particularly conducive to be needed Fast Heating or recovery and relies on the electrical equipment that thermostat is kept and control apparatus is operated.The example of this electrical equipment is baking box, drier, drinking water boiler, kettle, refrigerator, battery charger, bread baker, deep fat fryer, grill, pan, teppanyaki plate, system wafer machine and electric barbecue.Recognize that as those skilled in the art according to the type of electrical equipment, electric loading need not as having heating element in the kettle.Substitute or in addition, electric loading can be made up of pump, motor, cooling element etc.An example can be the refrigerator refrigerator, comprises extra cooling element that very fast refrigeration is provided or such as providing extra heating element for the hot drink racking machine.In addition, electrical equipment need not to comprise two electric loadings of same type or function, but can comprise two dissimilar electric loadings on the contrary.For example, the food blender of heating can comprise motor that drives blender and the heating element that food is incubated.

Recognize that as those skilled in the art though the electrical equipment of many examples discussed above is household electrical appliance, the present invention can be applicable to the electrical equipment of other types equally.For example, the racking machine of semi-commercial can be benefited from the power that two supply sockets are drawn to carry out extra function, for example the ability of two of packing simultaneously or quickening packing.As another example, help: be used for electric automobile, golf go-cart, send the battery charger of milk car and other motor vehicles to add charging quickly from the electrical equipment supply power of two supply sockets, for example to big wattage; Kitchen appliance, for example mixer, food processor and ice-cream freezer; Garden electrical equipment, for example trees or plant cutting machine, hay mover and shrub trimmer; Heater, for example fan heater, pharoid and filling type radiator; Air-conditioning unit; Office equipment, for example file crushing machine; Giant scale integration, for example server, large-scale computer and supercomputer; And instrument that in building industry, uses and electrical equipment, for example therefore concrete mixer, annular saw, drilling machine and other electric tools of typically having more high-power demand, can benefit from the present invention when using in such as family.

In another alternative, the present invention also is particularly conducive to and comprises the flow through electrical equipment of formula (flow-through) heater of fluid, for example the neat promise coffee maker of coffee/espresso/Kapp, washing machine, packing hot water machine etc. as required.Fluid is flowed through the formula heater can be benefited from the power supply that increases, for example, use the power of 4.5kW through two power lines (and selectable interlocking, described in top alternative), with only use 3kW to compare through single power cable, increased by 50% flow.In another example, use from the first fluid formula heater of flowing through and with linear series two independent fluids formula heater of flowing through is set to the flow through heating outlet of formula heater of second fluid.Two independent fluids formula heater of flowing through replacedly, can parallel way be set.In another alternative, can be by being used to realize improved flowing velocity from flow through two independent outlets of formula heater of fluid.In another alternative, dimeric electrical equipment can utilize first fluid to flow through the formula heater heating a certain amount of water in advance, and utilizes second fluid to flow through the formula heater to heat the temperature of this pre-heated water to expection.As another example, dimeric espresso coffee maker can utilize first fluid to flow through the formula heater with heating milk, and utilizes second fluid to flow through the formula heater to add hot water or to be used for the coffee of espresso coffee.As another example, dimeric electrical equipment can comprise cooler that the liquid that turns cold is provided and the heater of warm or hot liquid is provided.

Top execution mode and alternative also advantageously allow the electrical equipment of large-size to be easier to move, and needn't be wired to main power source regularly in order to satisfy its power supply requirement.For example, large-scale hot-water bottle need not to be wired to regularly main power source, but can be arranged in the parts top and be inserted into two power outlets or socket, still provides operation required large level power simultaneously.

Can also advantageously be used to van that power is provided the present invention, use two existing sockets and typically in camping, do not found such as the large power supply that the electric current that reaches 16 amperes is provided.As another advantage, family is provided with for example kitchen, when no longer installing or reset high-power electric appliance, in the time of for example high-power cooker, refrigerator refrigeration machine, washing machine and dryer etc., the double plug socket can be installed throughout so that the flexibility of increase to be provided.For example, in Britain, because the qualified electrician who the lead-in wire in the cooker is connected to new position is had legal requirements, so the position of mobile cooker is not a simple thing.Therefore, prepare for shifting electrical equipment that to make cooker be provided with according to the multi-cable plug of the present invention converter of multi-cable plug (or be suitable for) be favourable, thereby electrical equipment can be inserted any double socket that be arranged in the kitchen.

In the superincumbent execution mode, the base portion 3 of kettle comprises two heating elements.In a preferred embodiment, the discrete component in the electrical equipment is designed so that to use standardized size, thereby need not specific design or make internal components.For example, two 3kW elements that heating element can be a standard are compared with the kettle of single element, and it can provide heating faster.In another example, one in the heating element can be the 3kW element of standard, and another heating element can be the 1kW element of standard, this can utilize the 4kW power of combination and the improvement heating mode of operation is provided, and then only utilizes the heating element of lower-wattage that the insulation pattern of operation is provided.Under this mode, present embodiment is used the device of the low wattage of a plurality of standards, and has advantageously provided the electrical equipment of big wattage.

Can in other execution mode, develop this identical advantage---thereby the remarkable saving of individual devices and wiring harness is provided in the mill.The various aspects of each electrical equipment are treated as lower (standard) wattage, also allowed the producer to use production technology, test equipment and the test specification of standard.Each stage in supply chain all will embody this advantage.

In another alternative, multi-cable plug can comprise the intercalation part greater than two.For example, bigger electrical equipment can comprise four power terminations, and each all is connected to corresponding power supply, and compares with the electrical equipment with single plug, final electrical equipment can utilize four times power, and does not surpass each the power supply rated power in four power outlets or the socket.

Recognize that as those skilled in the art the plug and socket design will change according to the countries and regions that intention is used.For example, the power outlet or the socket panel of Europe and North America typically do not comprise corresponding on-off switch.Therefore, can change the interval of intercalation part 10a and 10b to adapt to switch arbitrarily.Also must adapt to other distortion of intercalation part 10a and 10b, for example different shape (using the circular plug head sometimes), variable width, change clockwise or counterclockwise angle, change the right angle (using angled socket panel sometimes) of plug face, perhaps change towards (for example vertically rather than side by side).

First execution mode and alternative have advantageously provided the single unit that cooperates with the multi-cable plug with two plugs, thereby in two plugs any all inserted or two plugs all disconnect.In this mode, prevent that the careless disconnection of user is inserted in two plugs in the power supply, and in two plugs another be become flexible and might be charged.And, disconnecting two plugs simultaneously by making the user, this guarantees that electrical equipment will complete and isolated from power.

Second execution mode

As shown in Figure 8, second execution mode provides the bread baker 51 of combination and wireless kettle 53 as integrated device 55.Integrated device 55 comprises base unit 57, and base unit 57 comprises bread baker 51 and integrated pedestal 59, is used to support kettle 53 and provides power to kettle 53.Base unit 57 has the power cable 61 that is used for connecting through the multi-cable plug 10 of first execution mode power supply.As described below, multi-cable plug 10 is provided with two independent power supplys that offer integrated device 55, and a power supply is offered bread baker 51, and another power supply is offered wireless kettle 53.

Socket panel 31a shown in Figure 8 shows the exemplary layout of outlet or socket and switch 33.As mentioned above, might carry out different layouts, and multi-cable plug 10 can be adjusted to adapt to various possible layouts according to socket panel.

Top execution mode and alternative provide the kettle and the bread baker of combination, but feature of the present invention can be applicable to other household electrical appliance, for example the microwave of the kettle of Zu He bread baker and coffee machine, combination and system evaporation coffee machine or combination and barbecue electrical equipment.

The 3rd execution mode

As shown in Figures 9 and 10, comprise having a pair of intercalation part 105a that is slidably mounted on it and the back casing 103 of 105b according to the multi-cable plug assembly 101 of this execution mode.Each intercalation part 105a and 105b comprise the plug terminal group 107 of the correspondence outlet socket 109 that is used for being inserted into twoport supply socket 111 separately.As described below, intercalation part 105 is adjusted the adjustment of the change of the interval between intercalation part 105a and the 105b being carried out to consider slidably, with variation that adapts to the interval between the adjacent outlet and/or the position that adapts to adjacent isolating switch 113, thereby the plug terminal 107 of two intercalation part 105a and 105b can be inserted in two outlets of twoport supply socket 111 simultaneously.

In this embodiment, intercalation part 105 effectively is provided with the gap of about 10mm between back casing 103 and twoport supply socket 111.By this way, the back casing 103 of multi-cable plug assembly 101 is avoided and is contacted adjacent to all isolating switches 113 as shown in Figures 9 and 10 of any switch that export.When withdrawing from multi-cable plug assembly 101 from twoport supply socket 111 when, the also favourable permission user in gap keeps or catches back casing 103.Can understand, the gap between back casing 103 and the twoport supply socket 111 should minimum be 5mm.

Figure 11 a and 11b are respectively the perspective view of multi-cable plug assembly 101 in plug terminal 107 sides, show the variable interval between the adjustable intercalation part 105.Figure 11 a shows and intercalation part 105 is arranged on immediate each other position two intercalation part 105a and 105b is inserted in the twoport socket that each outlet more closely is set together allowing.Position shown in Figure 11 a can also allow the lid 121 by the fuse that is arranged on back casing 103 back sides to enter separately fuse 123, and described fuse 123 is coupled to the power supply of being arranged to pass each intercalation part 105a and 105b.In the execution mode that illustrates, fuse 123 is arranged on the associated end place of the back casing 103 of multi-cable plug assembly 101.Fuse 123 can be arranged for the electrical equipment of 240V, for example the fuse of 13A.Figure 11 b shows the intercalation part 105 of the position that is arranged on separate De Gengkai, with allow with two intercalation part 105a and 105b be inserted into corresponding outlet be provided with in the twoport socket more opened at interval.

Return with reference to Fig. 9 and 10, locking 117 can be set on intercalation part 105a and 105b, when engaging with the back 118 of the width on the upper and lower surface of the back casing 103 that crosses multi-cable plug assembly 101, prevent that intercalation part 105 from sliding with convenient locking 117.In this embodiment, two lockings 117 are arranged on each intercalation part 5 upper surface that is arranged on intercalation part, a lower surface that is arranged on intercalation part.In the use,, must depress locking 117 to discharge lockable mechanism in order to adjust each intercalation part 105 slidably along the length of back casing 103.Recognize as those skilled in the art,, prevent that any slip from being favourable when multi-cable plug assembly in use the time.Therefore, inserted link or other devices that is fit to can be set, prevent that locking breaks away from or do not lock when multi-cable plug assembly 101 is inserted in the socket 111.Another benefit of anti-sliding stop is when the multi-cable plug assembly is inserted in the plugs and sockets, effectively prevents the hole that intercalation part is separately clamped socket, and this can cause and be difficult to the multi-cable plug assembly is broken away from from socket.Replacedly, can avoid clamping by discontinuous the increasing progressively of moving slidably is set.For example, this can realize by a plurality of grooves are set on the back casing on the multi-cable plug of all Fig. 9 as shown, be used to engage the outstanding tooth on each wall that is arranged on intercalation part.Outstanding tooth can have the thickness littler than each groove, thereby a spot of activity is provided, and perhaps Tu Chu tooth is flexible, thereby prevents to be clipped between plug terminal and the socket aperture.

Replacedly, have only a needs locking or locking in the intercalation part 105, to prevent with respect to 103 slips of back casing; Intercalation part 105a, 105b only need to align with socket and to be inserted in the socket, in case and intercalation part be inserted in the socket a then slip that will prevent the back casing in the blocking plug portion 105.In another alternative, but any of intercalation part 105 all is sliding with respect to the back casing preventing of locking, but because when intercalation part 105 all inserts when, back casing 103 is understood slidably, so this is not less preferred.

Can also be for each intercalation part 105a and 105b be provided with indicator light 119 on the front end face of back casing 103, LED for example, back casing 103 is relative with plug terminal 107.Indicator light can be set to indicate, for example, when when separately intercalation part 105 provides power, when electrical equipment when intercalation part 105 is separately drawn power, and/or the state of indication fuse 123 separately, for example, whether fuse 123 blows.

Insulating sleeve 125 extends from the back casing 103 of multi-cable plug assembly 101, is used for power line is delivered to the device of connection, and is as described in more detail below.By the cord grip part 127 of reinforcing insulating sleeve is connected to back casing 103 securely.As alternative, the cord grip of reinforcing partly can be replaced with rotatable cord outlet (typically on the family expenses flatiron, finding), rotatable cord outlet can rotate freely about the tie point of back casing 103 or pivot.As another alternative, the cord outlet that the oneself forms can be set, it is providing flexibility aspect the shape formation outlet lead-in wire of required any expection.

In the reference power supply outlet that can be fixed to typical twoport socket 111, independent intercalation part 105a and 105b have and standard plug similar forms and size.Recognize as those skilled in the art, have many dissimilar twoport sockets.Figure 22 a to Figure 22 e shows five kinds of dissimilar twoport sockets respectively, and each has two groups of outlet sockets 109 of the plug terminal that is used to receive corresponding intercalation part 105.Twoport socket 111-1, the 111-2 of example and 111-3 show corresponding outlet and are arranged to the diverse location of the isolating switch 113 adjacent with corresponding outlet, and so different distance between the socket of corresponding outlet.The upright position of outlet also can change.Twoport socket 111-4 and 111-5 show the example outlet with residual current device switch 115, and residual current device switch 115 is arranged on the different distance between the socket that has also caused corresponding outlet between the corresponding outlet again.Multi-cable plug assembly structure of the present invention can be become adapt to all standards and typical Britain twoport socket.

Figure 12 and 13 shows decomposition diagram, and this exploded perspective illustrates the device portion of the multi-cable plug assembly 101 of present embodiment.As shown in the figure, form each intercalation part 105 by housing 129, housing 129 has the arm 131 and 133 of two extensions of the top of the back casing 103 of being arranged to engage multi-cable plug assembly 101 and lower surface.In the time of assembling multi-cable plug assembly 101, for example, by plug 135 being ultrasonically welded to the arm 131 and 133 of extension, perhaps by after the not accessible trip bolt (not shown) that maybe can not operate plug 135 is fixed to the housing 129 of intercalation part 105, the housing 129 of intercalation part 105 engages back casings 103 and the arm 131 and 133 that extends is fixedly attached to plug 135.In this mode, make the user can not rewiring effectively to multi-cable plug assembly 101, cross over electrode and the lead-in wire in the back casing 103 that is contained in multi-cable plug assembly 101 to prevent the user.In this case, also must lead-in wire be connected to bus, absent-mindedness with link that can not rewiring thereby internal components can not become.

In this embodiment, multi-cable plug assembly 101 is designed to use with the standard Britain three end sockets of coplane.Therefore, the plug terminal 107 of each intercalation part 105a and 105b comprises earth terminal 107a, fire line terminal 107b and neutral terminal 107c, and they extend through the opening in the housing 129 and are configured for standard Britain plug in Britain's electrical socket of the standard of being inserted into.In this embodiment, through outstanding small embossment 137 plug terminal 107 is electrically connected to the back casing 103 of plug-assembly 101, small embossment 137 is formed on an end of plug terminal 107, and is relative with the end in being inserted into socket 109.As shown in figure 13, three outstanding small embossments 137 of intercalation part 105 are provided with in mode straight line, parallel, that separate, and be fixed in separately the groove 139, to be used for engaging slidably the respective electrical device of back casing 103, groove 139 is arranged on the back side of the back casing 103 of multi-cable plug assembly 101, and is as described below.Earth terminal 107a is provided with outstanding small embossment 137, and small embossment 137 basic ends from terminal 107a extend straight and received by the first groove 139a.Fire line terminal 107b is provided with outstanding small embossment 137, small embossment 137 from the arm of the lower surface that is connected to terminal 107b extend and by be arranged on the first groove 139a below the second groove 139b receive.Neutral terminal 107c is provided with outstanding small embossment 137, and small embossment 137 extends and received by the three-flute 139c that is arranged between the first groove 139a and the second groove 139b from the arm of the upper surface that is connected to terminal 107c.In fact, thereby because by making a terminal 180 with respect to another anglec of rotation upper and lower surface of overturning, fire line terminal 107b and neutral terminal 107c can use the identical plug terminal 107 with the outstanding small embossment 137 that is connected, so it is multi-form only need to make two kinds of plug terminal 107.The identical setting of terminal 107 and outstanding small embossment 137 all is provided for each of two intercalation part 105a and 105b.

The perspective view of the back casing 103 of the multi-cable plug assembly of Figure 14 is removing of present embodiment intercalation part 105.Figure 15 shows the back casing 103 that does not have the multi-cable plug at back side assembly 101, and shows the inner member of back casing 103.As shown in the figure, back casing 103 comprises the sidewall that is provided with circular edge in this embodiment, the common flat upper wall that is provided with the sunk part of a plurality of back 118 with the width that passes upper surface, also advantageously be provided with effective grip area, being used for removing multi-cable plug assembly 101 with comparalive ease from socket, and flat reinforcing diapire usually.Opening is set in diapire is inserted in the back casing 103 of multi-cable plug assembly 101 to consider a plurality of leads 141, a plurality of leads 141 is enclosed in the insulating sleeve 125 that is connected to back casing 103.

In this embodiment, lead-in wire 141 comprises wall scroll ground wire 141a, two independent live wire 141b and two independent neutral line 141c, the insulated from each other and insulating sleeve by separately and be not subjected to unintentionally contact.Recognize that as those skilled in the art the size of lead-in wire depends on the load of single power demand.Ground wire 141a is electrically connected to common ground bus 143a, common ground bus 143a is arranged to pass the outstanding small embossment 137 separately that groove 139a receives two earth terminal 107a, groove 139a is located in the back casing 103 of multi-cable plug assembly 101.Two live wire 141b are electrically connected among two live wire bus 143b corresponding one, and live wire bus 143b is arranged on each side of back casing 103 through corresponding fuse 123.Two live wire bus 143b are arranged to pass the outstanding small embossment 137 separately that groove 139b receives two live wire 107b, as mentioned above.Similarly, two neutral line 141c are electrically connected to corresponding of two neutral bus 143c, two neutral bus 143c are arranged to pass the outstanding small embossment 137 separately that groove 139c receives two neutral terminal 107b, as mentioned above.In this embodiment, the structure intercalation part 105 physical size so that bus 143 always covered by intercalation part 105.According to present embodiment, in order to realize covering and move to adapt to all standards and typical Britain twoport socket, intercalation part 105 has the width of 50mm, is used to enter the groove 139 wide 22mm of bus 143, and small embossment 137 wide 6mm.Certainly, it will be understood by those skilled in the art that many sizes that other are fit to are possible.For example, intercalation part 105 can have 25 in the 55mm scope width and 25 to 55mm height.The width of groove 139 can be between 5 to 30mm.The width of small embossment 137 can be between 1 to 10mm.

As mentioned above, in this embodiment, outstanding small embossment 137 is arranged in the intercalation part 105, the bus 143 that inside is connected is arranged in the back casing 103 of multi-cable plug assembly 101.Figure 16 is the feature profile that crosses the multi-cable plug assembly 101 of present embodiment, and the inside that shows between outstanding small embossment 137 and the bus 143 connects, as mentioned above.Shown in close-up illustration, outstanding small embossment 137 is slidably received within the U-shaped part of bus 143 and with this U-shaped and partly is electrically connected, the U-shaped part of bus 143 has effectively limited the slide relative of outstanding small embossment 137 along the length of bus 143, has kept constant internal electrical to connect simultaneously.Recognize as those skilled in the art, in interchangeable execution mode, outstanding small embossment 137 can be arranged in the back casing 103 of multi-cable plug assembly 101, and bus 143 is arranged in the intercalation part 105.In addition, will recognize that it is schematically that the inside that illustrates connects, and the small embossment that the shape of bus must be fit to be easy to outstanding is electrically connected fully to satisfy the load needs.

Recognize as those skilled in the art, can make between the live wire part of molded outer side surface of the plasticity of back casing 103 and bus 143 apart from optimization to improve leakage distance.The part of the small embossment 107 in the bus 143 can be inserted into the insulating material encapsulation, thereby, then the live wire part can be do not entered if intercalation part 105 disconnects with back casing 103 unintentionally.And, thereby electric leakage and clearance distance can need not independent groove in the enough big formwork on bus.

One of skill in the art will appreciate that because some electric devices (for example, electric lead and/or fuse) are not arranged in the intercalation part 105, but in back casing 103, so do not have typical plug complexity according to the intercalation part 105 of present embodiment.Therefore, it is fairly simple to make intercalation part 105, for example, inserts forming technique by using around terminal.

The 4th execution mode

Figure 17 a is the perspective view of the multi-cable plug assembly 151 of the 4th execution mode of the present invention to 17c.In this embodiment, multi-cable plug assembly 151 is provided with handle 153, the handle 153 pivotable back casings that are installed to multi-cable plug assembly 151 are used for moving between the favorite places shown in Figure 17 a and the expansion shown in Figure 17 b, the position that can hold with a firm grip.Shown in Figure 17 a and 17b, the multi-cable plug assembly engages with twoport socket 111.By from favorite places to the position pivoting handle 153 of can holding with a firm grip, the user can grasp handle 153 and is drawn multi-cable plug 153 easily so that it breaks away from from twoport socket 111, shown in Figure 17 c.

In addition, in this embodiment, the shank end of handle 153 is provided with projecting part 161, and this projecting part 161 is arranged to move to can hold the position with a firm grip the time surface in abutting connection with twoport socket 111 when handle 153.When projecting part 161 contacted the surface of twoport sockets 111, projecting part 161 actions began multi-cable plug assembly 151 is broken away from from twoport socket 111, are relatively easy to break away from further favourable considering.

Figure 18 is another perspective view of the multi-cable plug assembly of the 4th execution mode.Shown in Figure 17 and 18, except intercalation part is not to fix connection by described plug before, intercalation part 105a and 105b are also to be connected to the back casing 157 of multi-cable plug assembly 151 slidably with the same way as described in the 3rd execution mode.Anchor clamps by passing the back casing (be in clearly purpose is not shown), perhaps, intercalation part 155 fixedly can be remained to back casing 157 by himself being connected to any other clamping device (thereby pulling force is applied to intercalation part rather than back casing) that is fit to of back casing 157 or intercalation part 155.

In addition, as shown in figure 18, handle 153 has and stretches out or the outstanding part that surpasses back casing 157, can lead to handle 153 easily when handle 153 is in favorite places.And, for favourable guiding user holds the mid portion of handle 153, have balanced pulling force on the multi-cable plug assembly 101, and form the profile of handle 153 thereby make.In addition, the support bar (not shown) can be set so that handle 153 is connected to intercalation part 105, even thereby the user holds handle 153 in off-centered position, support bar will work so that load disperses to pass intercalation part, thereby guarantee that the basic while of intercalation part all breaks away from from its socket separately.

Figure 19,20 and 21 shows the decomposition diagram of the multi-cable plug assembly 151 of the 4th execution mode, and shows the intercalation part 155 of multi-cable plug assembly and the inner member of main body 157.Similar device in this execution mode provides and the identical Reference numeral of its homologue separately described in top the 3rd execution mode, and the inside of these devices connects and the mode of operation identical with described in the 3rd execution mode.

Therefore shown in Figure 20 and 21, in this embodiment, fuse 123, can lead to through separately fuse cover 121 when intercalation part 105 is positioned to be separated from each other farthest between intercalation part 105a and 105b and its electric device separately in central authorities.

Execution mode above proposing still one of skill in the art will appreciate that the combination in any of plug described in above-mentioned execution mode and the alternative and electrical equipment is possible as independent execution mode.

For example, in described in the above the 3rd execution mode, the multi-cable plug assembly is provided with and is used for two intercalation parts being electrically connected with the corresponding outlet of twoport socket.One of skill in the art will appreciate that as alternative, can adjust the multi-cable plug assembly be provided for a plurality of outlets in corresponding one be electrically connected greater than two intercalation part.In addition, will recognize, for example, different intercalation parts can be used together with identical back casing, with the various plug adapters that are provided for using together with identical back casing.
