Definitions

  • the present invention relates to power connection means and, more particularly, to electrical power sockets and outlets. More specifically, the present invention relates to power sockets more commonly known as universal power sockets.
  • Electrical power connection means is essential for power delivery between a power source and a load.
  • power coupling means such as plugs and socket pairs
  • plugs and socket pairs are widely used.
  • power outlets more commonly known as wall sockets are available in many buildings or structures at distributed locations so that power can be more convenient coupled to electrical appliances using compatible plugs.
  • connection means more commonly known as universal sockets or adaptors are known.
  • Such universal sockets and adaptors are, for example, described in US Patent Nos. 5,007,848 , 5,836,777 and 6,010,347 .
  • Conventional universal-type sockets typically comprise a pair of base contact receptacles and a third contact receptacle which are disposed at the vertices of an isosceles triangle.
  • the pair of base contact receptacle is disposed at the base vertices of the isosceles triangle and the third contact receptacle is disposed at the top vertices of the isosceles triangle.
  • Each of the contact receptacles and the associated metallic contacts are configured so that various types of electric plugs of different prong sizes can be inserted into the corresponding contact receptacles for making electrical connections.
  • conventional universal-type sockets are designed to fit as many varieties of plugs as possible which means some plugs may be very loosely received within the contact receptacles while other plugs may be too-tightly received.
  • the circular prongs of the more commonly available standard plugs have a diameter between 3.7 - 5.1 mm.
  • Such a range when translated into the design of a universal socket or adaptor, means that if a contact mechanism can lightly receive a 5mm circular prong and a prong with non-circular cross-section, such as a base prong of a British BS1363 13A plug, is tightly received, an electrical plug with a 3.7mm circular prong will be in loose contact and this may lead to overheating, fire or other hazards.
  • GB-A-2336478 discloses an adapter and socket structure adapted for use on a securing frame of a socket of European specification including a socket body provided with an electrically conductive frame at either side thereof to which a corresponding wire clamping reed having a wire clamping portion may be assembled.
  • a German plug adapter seat may normally be connected to a European socket so that a guide post therein pushes aside a safety slide cover plate inside the European socket so that, when using the plug of a European made electric appliance, there is no need to use a tool to push aside the safety slide cover plate.
  • an electrical socket according to claim 1.
  • the isosceles triangular arrangement formed by the contact receptacles of a first socket region and said second socket region are in inverted relationship with respect to each other.
  • An axis joining the base pair of contact receptacles of said first socket region is preferably parallel to an axis joining the base pair of contact receptacles of said second socket region, wherein the contact receptacles of said first and second socket region are on the vertices of a trapezium.
  • the first socket region is preferably disposed between the pair of base contact receptacles and the third contact receptacle of said second socket region.
  • Each of said first and second protective members preferably comprises an inclined surface which is below the contact receptacle it is covering, the inclined surfaces tapering away from the axis joining the base contact receptacles of said pair of second contact receptacles in a manner such that said first and second protective members are urged towards to the open position upon insertion of an electrical plug of the second type.
  • the second protective member is pivotally movable about an axis which is substantially orthogonal to an axis joining the base contact receptacles of said second socket region.
  • the second protective member is preferably arranged so as to pivot about said axis upon non-symmetrical insertion of a pair of prongs into said pair of base contact receptacles.
  • Each one of the pair of base contact receptacle of said first socket region is preferably adapted for receiving a prong of an electrical plug of diameter between 3.7 to 5.1 mm.
  • an electrical socket which is adapted for receiving electrical plugs of different standards are more commonly referred to as a “universal socket” or an "international type socket".
  • the term “universal socket” is only used for convenience and is not meant to incorporate any specific technical meaning for the avoidance of doubt.
  • a universal socket includes an international type socket which is for receiving plugs conforming to various national standards.
  • FIG. 1 there is shown a first preferred embodiment of a socket of this invention.
  • This socket 100 is adapted to receive electrical plugs of various national and international standards with some examples illustrated in Tables A and B below for convenience.
  • the socket of Fig. 1 comprises first (1) and second (2) socket regions for receiving electrical plugs of a first type and a second type.
  • Two socket regions are provided in this invention to cater for electrical lugs of various prong sizes and configuration so that plugs will not be too loosely received in the contact receptacles to mitigate the risk of overheating and/or arcing which may cause fire hazards or personal injuries.
  • Each of the first socket region (1) and the second socket region (2) comprises a pair of base contact receptacles and a third contact receptacle, with the three contact receptacles forming the vertices of an isosceles triangle.
  • Each contact receptacle comprises a contact aperture and a contact mechanism which is directly underneath the contact aperture.
  • the contact aperture defines the size and shape of an aperture which is accessible to a contact prong of an electrical plug upon insertion.
  • the contact aperture is typically formed on a rigid front housing which is usually made of durable plastics so that the prong contact mechanisms and the underlying wiring connections are insulated from the outside.
  • the contact mechanism typically comprises metallic contacts which form a resilient bracket-type catch so that an appropriate prong of an electrical plug can be compressively held for good electrical contact.
  • the pair of base contact receptacles (121, 122) (111, 112) is on the base vertices of the isosceles triangle while the third contact receptacle (113, 123) is on the top vertice.
  • the respective electrical connection of each of the individual contact receptacles of the first and second socket regions of this socket is more particularly illustrated in Fig. 1 using various standard nomenclatures for easy reference.
  • the pair of base receptacles is respectively connected to the N (neutral) and L (live) terminals with the third contact receptacle (113, 123) is for connection to the E (earth) terminal. It can be seen from Fig.
  • contact receptacles are arranged so that contact receptacles of the first socket region and the second socket region on the same side of the third contact receptacles are for connection to the terminal of the same marking.
  • contact receptacles on the left side of the third contact receptacles are connected to the "N" terminals while those on the right side are connected to the L terminals with the third contact receptacles for connection to the E terminals.
  • the second socket region (2) is adapted for receiving electrical plugs of the second type (Type 2 sockets) as set out in Table B below for illustrative purposes.
  • the second type plugs include plugs conforming to the following standards, British standard BS1363 (250V, 13A), BS546 (250V, 5A), Chinese standard GB1002 (250V, 10A), Australian standard AS3112 (250V, 10A), IEC standard IEC60884-1 (250V, 16A).
  • the second column on Table B illustrates how the various plugs are fitted into the second socket region and how the second socket region universally accommodates the various plugs.
  • the Chinese standard plug GB1002 comprises two parallel prongs of a substantially rectangular cross-section with the longer sides of the pair of prongs parallel to each other.
  • the portion of the contact aperture adapted for receiving the pair of parallel prongs of this GB1002 plug is formed on the pair of base contact apertures proximal to each other.
  • the portion of the pair of contact apertures closest to each other are also shaped to receive a pair of divergent prongs of the AS3112.
  • the third contact aperture on the second socket region is also formed and shaped to receive the third prong of the plugs where an electrical plug comprises a third prong.
  • the IEC 60884-1 plug is similar to the configuration of GB1002 but with a third prong and the second socket region is provided with an appropriately shaped and configured third contact aperture.
  • the BS1363 plug comprises a pair of prongs having a substantially rectangular cross-section with the longitudinal axis of the pair of prongs substantially co-linear.
  • the third prong of the BS1363 plug has a substantially rectangular cross-section with the longitudinal axis substantially orthogonal to the line joining the pair of base prongs forming the base vertices of an isosceles triangle.
  • the contact apertures of the second socket region are dimensioned to receive the pair of base prongs as shown in row 13 of Table B.
  • the top contact aperture is also dimensioned to receive the top prong of this plug.
  • the BS546 plug comprises prongs of a substantially circular cross-section and the contact apertures are accordingly dimensioned to accommodate the three substantially circular prongs, preferably in a closely-fitted manner.
  • the first socket region is adapted for receiving various plugs which are collectively referred to as type-one plugs, examples of which are set out in column 1 of Table A.
  • the type-one plug comprises a pair of substantially parallel prongs with a substantially circular cross-section.
  • the base contact apertures of this first socket region are dimensioned so that circular prongs with a diameter between 3.7mm and 5.1 mm can be received in a closely-fitted manner under compressive contact of the resilient metallic contacts underneath the contact apertures.
  • the range of diameter of the prongs to be receivable by the base apertures can be varied according to individual applications without loss of generality.
  • Typical type-one plugs are shown in the second column of Table.
  • a pair of alternative circular apertures are provided intermediate the pair of base contact apertures as shown in the region one illustration. More particularly, the pair of alternative circular contact apertures comprises a first circular aperture co-linear with the pair of base contact apertures and a second one which is offset from the line joining the two base apertures. The first alternative circular aperture which is in line with the pair of base apertures is provided to receive a third prong of a plug of a corresponding configuration such as the Italian CEI23-16 plug with three contact prongs.
  • the offset middle contact aperture is for receiving the offset prong of Swiss plug/Spanish plug SEV1011.
  • the dimension of the base contact receptacle of the first socket region is adapted for receiving a plug with prongs of a circular cross-sectional shape and dimension, while a plug comprising a prong or prongs of non-circular cross-sectional shape is for the second socket region.
  • the first socket region and the second socket region are disposed so that the isosceles triangles formed by the corresponding contact apertures are in inverted relation to each other.
  • the vertices corresponding to the two pairs of base contact receptacles substantially forms the vertices of a trapezoid with the top vertices of the pair of isosceles triangles pointing towards each other.
  • Fig. 3 illustrates the application of the Fig.1 configuration as a wall socket with a front housing mounting plate made of durable plastics.
  • the first and second socket regions are disposed so that the pairs of isosceles triangles formed by the respective contact receptacles are also inverted relative to each other.
  • the first socket region (comprising 211, 212 and 213) is completely disposed intermediate the pair of base contact receptacles (221, 222) and the third top receptacle (223) of the second socket region.
  • the size of the trapezoid is substantially reduced, resulting in a more compact design so that the effective area to be occupied by all the contact receptacles are substantially identical to the dimensions of a typical single-standard socket.
  • the configuration of the Figs. 2 and 2A universal socket is applied as an illustrative example of a wall socket as shown in Fig. 4 .
  • the two socket regions are arranged as two pairs of inverted isosceles triangles, it will be appreciated that it is not necessary so and the two triangles can be arranged in a parallel configuration.
  • protective means is provided. Because the second socket region is best catered for type-two plugs which comprise both two-pronged and three-pronged plugs, conventional shutter-gate type protective members comprising an insulated shutter gate which normally closes the three-contact apertures but will be opened when a rigid post is inserted into the third contact receptacle is inappropriate.
  • the protective means comprises a first shutter-gate sub-assembly (320) and a second shutter-gate sub-assembly (340) which together form a shutter-gate assembly (300).
  • the shutter-gate assembly (300) comprises a plurality of insulated shutter members which are movable between a closing position and an opening position. In the closing position, the insulating shutter members are directly underneath the contact apertures while, at the opening position, the insulating shutter members are clear of the contact apertures so that the contact mechanisms underneath the contact aperture can be accessible from the outside.
  • the shutter-gate assembly is under spring bias so that the shutter members are normally at the closing position by spring urge.
  • a plurality of coil springs (350) is used as example.
  • the first shutter-gate sub-assembly (320) comprises a rigid body moulded of durable plastics with a pair of wing-like shutter members (322, 324) symmetrically formed about a central axis (326).
  • the first shutter-gate sub-assembly is movable relative to the second shutter-gate sub-assembly along the axial direction of the central axis (326) and between an opening position and a closing position. In the closing position, the pair of wing-like shutter members is directly underneath the base contact apertures of the second socket region and, at the opening position, the shutter members are cleared away from the pair of base contact apertures of the second socket region to allow insertion of a pair of prongs of an electrical plug of the second type.
  • Each of the wing-like shutter member of the first shutter-gate sub-assembly (320) is tapered along the axial direction of the central axis so that when a pair of prongs of an electrical plug with a projection falling on the shutter members is inserted towards the shutter members (322, 324), the tapering will cause the shutter members to be urged in a direction along the axial direction of central axis (326), thereby opening the contact apertures.
  • the tapering is towards the axial end of the shutter members which approaches the third contact receptacle of the second socket region, as is more clearly seen in Fig. 8D .
  • a spring means is disposed at the distal end (that is, the end which is away from the tapered end) so that when the shutter member is moved towards the distal end for opening the contact aperture, spring bias will be built-up to store energy to return the shutter members towards the closing position.
  • a coil spring is installed and retained in position by an axial protrusion (328) formed at the distal end of the shutter member.
  • the lateral dimension (that is, the width) of the wing-like shutter members are adapted so that the maximum lateral extent of the wing-like shutter members corresponds to the maximum extent of a pair of base contact-prongs of a two-pronged type-two electrical plugs.
  • the pair of wing-like shutter member are also shaped and dimensioned so that the two prongs of a type-one plug cannot act on the two tapered regions on the shutter members. As a result, the pair of shutter members cannot be opened by a type-one two-pronged plug.
  • the first shutter-gate sub-assembly (320) further provides means to alleviate the risk of unbalanced insertion, for example, due to insertion of a single post into one of the base contact receptacles of the second socket region. This is achieved by supporting the first shutter assembly at the longitudinal ends of the central axis (326) so that the pair of shutter members will be pivoted above the central axis (326) when subject to an unbalanced insertion force as more particularly depicted in Figs. 8A to 8D . In addition, this arrangement of the first shutter assembly also alleviates the risks of unsymmetrical or tilted insertion of the two prongs into the socket.
  • the first shutter-gate sub-assembly is also pivotable relative to the second shutter-gate sub-assembly and about a longitudinal axis substantially along the line "E" in Fig. 1A .
  • the second shutter-gate sub-assembly comprises a fork-like member made also of durable plastics with a first shutter member (342) formed on one side of the fork-like body and a pair of bifurcated shutter member (344, 346) formed at the other side and extending along an opposite direction to the first shutter member (342).
  • the second shutter-gate sub-assembly is also movable between a close position and an opened position.
  • the shutter members of this second shutter-gate sub-assembly are underneath the three contact apertures of the second socket region under normal circumstances so that, in combination with the first shutter-gate sub-assembly, all the three contact apertures of the second socket region are closed unless and until an appropriate electrical plug is inserted.
  • the first shutter member (342) of this second shutter-gate sub-assembly is accessible through the third contact receptacle (the Earth Terminal) of the second socket region and the shutter member extends substantially axially away from the pair of fork-like shutter members.
  • the first shutter member (342) is also tapered towards its free end, as more particularly shown in Figs. 5A and 5B . With this tapered arrangement, when a third prong of a type-two electrical plug is inserted into the third contact aperture, the downward insertion of the third prong towards the tapered end will push the second shutter-gate sub-assembly towards the opening position, as more particularly shown in Fig. 6 , thereby opening the entire sub-assembly to allow plug insertion.
  • the first shutter- gate sub-assembly is embraced between the pair of fork-like members, the movement of the second shutter-gate sub-assembly towards the opening position will also drive the first shutter-gate sub-assembly towards the opening position, thereby opening all the three contact apertures against spring bias. Furthermore, since the pair of fork-like members are not tapered, when a pair of circular prongs corresponding to the foot-print of the pair of fork-like members is inserted against the pair of fork-like shutter members, there will be no sliding movement unless there is a third post acting on the tapered first shutter member.
  • Figs. 8, 8A and 8B illustrate in various views the pivotal movement of the first shutter-gate sub-assembly relative to the socket housing and the second shutter-gate sub-assembly when subject to an unbalanced insertion force.
  • Figs. 9 and 9A illustrate the situation when a pair of posts of a type-one two-pronged electrical plug is inserted into the second socket region. Because the foot-print of the type-one prongs are outside the maximum lateral extent of the wing-like shutter members of the first shutter-gate sub-assembly, the pair of prongs will fall partially on the fork-like member and, in the absence of the driving of a tapered and of one of the shutter members, the shutter members will remain close.
  • the protective means described above have been described with reference to a universal socket comprising a first socket region and a second socket region, it will be appreciated that this protective means can be applied in a universal socket with only a second-socket region without loss of generality.
