Abstract
Description
- THIS INVENTION relates to a power supply structure having sockets into which plugs can be inserted.
- For use in places such as laboratories and kitchens, power supply units which are mounted in an opening provided in a working surface have been commercially exploited. An example of such a unit is found in the PCT specification
W02006/34513 - The movable centre column of such a unit has a raised, operative position in which the sockets are accessible above the working surface and a stored inoperative position in which all but a top cap of the column is below the working surface.
- The type of socket used in Germany is referred to as a Schuko socket. It comprises a cylinder which is closed at one end by a transverse wall. Guides in the form of ribs and grooves extend axially of the cylinder and the transverse wall has two holes in it. A Schuko plug is in the form of a short cylinder with external ribs and grooves that match those of the socket. The plugs can consequently be inserted into the sockets in only predetermined orientations. Two metal pins protrude from one end of the plug cylinder and these pass through the holes in the transverse end wall of the socket.
- All the electrical connections of the Schuko socket, apart from two earth connections, are on the side of the transverse end wall opposed to the space where the plug is located. As a consequence the depth of a Schuko socket plus its related electrical connections is significant.
- The transverse dimensions of the movable column of the type of power supply unit discussed are limited for practical reasons and for aesthetic reasons. Also, the distance through which the movable column can be lifted is also limited for reasons of stability and aesthetics.
- The consequence of this is that only a single vertical array of Schuko sockets can be provided with generally not more than three sockets in the vertical array.
- The depth of the Schuko socket cannot be reduced or cannot be reduced sufficiently to enable two vertical arrays of sockets to be provided back-to-back and thereby to enable an increased number of sockets to be provided on a column of acceptable dimensions.
- The present invention seeks to overcome this problem by reducing the space required for the electrical connectors of the sockets.
- According to the present invention there is provided a power supply structure comprising two rows of Schuko sockets, the rows being arranged back-to-back, the Schuko sockets having transverse end walls with plug pin holes in them and there being a shutter behind each end wall, electrical connectors for the sockets being in units located between the shutters, each unit including a pair of receptacles which are connected to the live bus bar and a pair of receptacles which are connected to the neutral bus bar.
- Each unit can comprise a moulding of synthetic plastics material which is in the form of a complete loop with a cross bar extending across the loop to provide receptacle spaces on each side of the cross bar, there being walling defining spaced pathways for live and neutral bus bars, the pathways extending generally transversely with respect to the cross bar, there being a pair of plug pin receptacles on each side of the cross bar externally of the mouldings, one pair of receptacles being connected to the live bus bar and the other pair of receptacles being connected to the neutral bus bar.
- Each bus bar can include projecting tabs, and the receptacles of each pair of plug pin receptacles can be joined by a bar, each bar being formed adjacent one end with a tab which is connected to one of the tabs of one of the bus bars thereby to connect the receptacles to the neutral and live bus bars.
- In this form the live and neutral bus bars preferably extend one along each side of the row of units.
- In the preferred embodiment each shutter is mounted for rotation about its centre, there being a skew surface on each side of the centre mounting which surfaces are encountered by the pins of a plug being inserted into the associated one of said sockets.
- Spring strips can be provided for returning said shutters to the positions in which they close off the plug pin holes upon withdrawal of a plug.
- To ensure that the pins of plugs being inserted into the sockets do not touch, the back-to-back sockets are arranged with a line joining the plug pin openings of one socket at right angles to a line joining the plug pin openings of the other socket whereby the pins of plugs inserted through back-to-back sockets enter different receptacles.

- The
column 10 illustrated in the drawings comprises two identical mouldings 12.1 and 12.2 arranged back-to-back. The moulding 12.1 (Figures 1A and1B ) comprises two elongate, spaced, parallel side walls 14.1, 14.2 and aplatform 16. Three cylindrical sockets 18.1, 18.2 and 18.3 are moulded integrally with theplatform 16, the cylindrical walls of the sockets extending in both directions from theplatform 16.Ribs 20 are provided on the inner surfaces of the cylindrical walls. The plugs (not shown) which fit in the sockets have complementary grooves thereby to predetermine the position of the plugs with respect to the sockets.Transverse end walls 22 with plug pin holes 24 in them close off one end of each socket 18.1, 18.2 and 18.3. Lines joining the pin holes 24 are at 45° with respect to the side walls of the moulding. Consequently, when the mouldings are placed back-to-back, the pin holes 24 of one moulding are not aligned with the pin holes of the other moulding. - The side walls of the moulding 12.2 are designated 14.3 and 14.4 (
Figure 1 ) and its platform is designated 16.1. The sockets of the moulding 12.2 are designated 18.4, 18.5 and 18.6. -
Latches 26 are provided for holding the mouldings 12.1, 12.2 together. Eachlatch 26 has arib 28 along its free end. The wall 14.1 has tworectangular holes 30 in it. The moulding 12.2 is similarly configured. When the two mouldings are presented to one another the walls 14.1 to 14.4 cam thelatches 26 inwardly until theribs 28 snap into theholes 30. - Turning now to
Figures 4 to 6 , the moulded plastics material component illustrated is designated 32. The component defines twopaths 34 which are bounded externally byouter walls 36 which stand proud of abase 38. Thebase 38 is of square shape. Two partcircular walls 40 also stand proud of thebase 38 and terminate close to theouter walls 36. - Within the space between the
walls 40 there is across bar 42 and twowalls 44 and 46. Eachwall 44, 46 has generallystraight portions 48 which extend from thecross bar 42. The pairs ofportions 48 are joined bycurved sections 50 which sections are approximately parallel to thewalls 40. - Gaps in the
walls 44, 46 are shown at 52, 54, 56, 58 and 60. - The
cross bar 42 has acentre section 62 consisting of twoparallel walls 64 with a gap between them and two offsetend sections 66. Thesections 66 are offset in opposite directions from the gap bounded by thewalls 64 of thesection 62. - The component shown in
Figures 10 to 14 is designated 68 and comprises a generallyrectangular platform 70 with four plug pin holes 72 in it. The holes are in a rectangular array. - Two
posts 74 protrude from one surface of theplatform 70 and twoangled stops 76 are provided on the same surface. A pair of closely spacedparallel walls 78 define an L-shaped space for receiving and locating a metallic spring strip as will be described. At the centre of theplatform 70 there is apin 80. -
Reference numerals 82 designate rings which are integral with, and protrude upwardly from, theplatform 70. Four lockingelements 84 are provided on the underside of theplatform 70. - One
component 32 and twocomponents 68 are provided in the space between each pair of back-to-backtransverse walls 22, thecomponent 32 being between the twocomponents 68. Theelements 84 interlock with the slots designated 32.1 (Figures 4 and5 ) that the configuration of thecomponent 32 provides thereby correctly to position eachcomponent 68 with respect to the interveningcomponent 32. Onecomponent 68 has been omitted from each ofFigures 3 and7 enable thecomponent 32 to be seen. - An electrically conductive metal strip 86 (
Figure 15 ) forming the neutral component extends along theleft hand paths 34 of all threecomponents 32. Thestrip 86 is bent to conform to the shape of thepaths 34 and punched and bent to formtabs 88. - Each of the structures designated 90 (see
Figures 8 and 9 ) is constituted by a strip of electrically conductive metal slit and bent to provide twoarcuate sections 92 between which the pins of a plug inserted into the associated socket pass. Thesections 92 are pushed apart by the plug pins as the plug enters thereby to ensure that there is electrical contact between thesections 92 and the pins. Thesections 92 are joined by abar 94 which has, at the centre thereof, anotch 96 in one edge and aprotrusion 98 along the other edge. Thebar 94 is slit at 100 and a portion of the bar is pushed out to form a connectingtab 102. - The tabs 88 (
Figure 15 ) co-operate with thetabs 102 so as electrically to connect thestrip 86 to thestructures 90. - Two
structures 90 are mounted on eachcomponent 32 as best seen inFigure 7 and lie one on each side of thecrossbar 42. The pairs ofstructures components 32. - A further electrically
conductive metal strip 86 passes through theright hand paths 34 of thecomponents 32 and forms the live bus bar. Thestrip 86 forming the live bus bar is inverted with respect to the strip forming the neutral bus bar. Thus thestructure 90 on one side of thecross bar 42 is live and thestructure 90 on the other side of thecross bar 42 is neutral. - An electrically conductive earth plate 104 (see
Figure 17 ) is a press fit into a transverse groove (seeFigures 10 and 12 ) of theplatform 70. Theearth plate 104 has twoholes 106 in it. Therings 82 which are integral with, and protrude upwardly from, theplatform 70 enter theholes 106 in theplate 104. This ensures that the plug pins cannot touch the earth plate. - An
upstanding contact 108 of resilient, electrically conductive metal is provided at each end of theplate 104. More specifically a sub-plate with thecontacts 108 at each end thereof is provided underneath theplate 104. Thecontacts 104 pass through holes 110 (Figure 1B ) in theend walls 22 of the related socket and protrude into the space which a plug in the socket occupies (seeFigure 1A ). Theposts 74 limit outward movement of thecontacts 108. Eachearth plate 104 is connected by atab 112 to an earth strip 114 (seeFigure 16 ) which extends along the outside of each component 32 (see particularlyFigure 7 ). Thestrip 114 is punched and bent to providepockets 116 into which thetabs 112 fit. Thestrip 114 has sets ofpockets 116 along each edge thereof. Thestrip 114 can thus be used as the earth for both rows of sockets. - A
shutter 118 is mounted on thepin 80. Anupward extension 120 of the shutter lies immediately adjacent thetransverse wall 22 of the associated socket. Theshutter 118, as best seen inFigure 18 , has skewtop surfaces 122 on either side of theextension 120. Theshutters 118 as shown inFigure 2 cover the plug pin holes 72 of thecomponent 68 which register with the plug pin holes 24 of the socket. As the pins of the plug being inserted encounter the skew top surfaces 122 of theshutter 118, theshutter 118 is rotated to uncover theholes 72 and permit the pins to pass through into the generally circular spaces defined by thestructures 90. The pins enter therings 82 of the opposedcomponent 68. - Spring strips 124 (
Figure 19 ) located in the gaps between thewalls 78 bear on theshutters 118. When the plug is withdrawn thestrip 124, which was deformed as theshutter 118 turns whilst the plug is being inserted, pushes the shutter back to the position illustrated. Such movement is limited by thestops 76. - It will be understood that the opposed sockets such as 18.2 and 18.5 can each receive a plug. The pins of each plug enter the structures on opposite sides of the
cross bar 42 thereby to connect to the live and neutral of the power supply system with the pins of the plugs indifferent sections 92.
