The socket of Fig. 1 comprises first receptacle area 1 and second receptacle area 2 of the plug that is used to receive the first kind and second type.Two receptacle area are set in the present invention catering to the plug of various pin sizes and structure, thus make plug not too loose ground be received in the contact receptacle, to eliminate overheated and/or may cause the danger of the arc discharge of fire or personal injury.
Referring to figs. 1 through Fig. 4 and Table A and B, second receptacle area 2 is suitable for receiving the plug (2 type socket) that appended table B is second type listed of the purpose of illustration.More particularly, the second type plug comprises the plug that meets following standard, and British Standard BS1363 (250V, 13A), BS546 (250V, 5A), Chinese Industrial Standards (CIS) GB1002 (250V, 10A), Australian Standard AS3112 (250V, 10A), IEC standard IEC 60884-1 (250V, 16A).Second hurdle among the table B shows how various plugs are assembled in second receptacle area and how second receptacle area holds various plugs usually.For example, Chinese Industrial Standards (CIS) plug GB1002 comprises that two cross sections are the parallel pin of essentially rectangular, and this long limit to pin is parallel to each other.This contact apertures to parallel pin that is suitable for receiving this GB1002 plug partly is formed on a pair of contact apertures down close to each other.In addition, hithermost each other a pair of contact apertures part also forms a pair of pin of dispersing that receives AS3112.In addition, the 3rd contact apertures on second receptacle area also forms and is configured as at plug and comprises the three-prong that receives plug under the situation of three-prong.The similar of IEC60884-1 plug and GB1002 but have three-prong, second receptacle area is provided with the 3rd contact apertures of suitable shaping and structure.The BS1363 plug comprises that a pair cross-section is the pin of essentially rectangular, and this is to the longitudinal axis conllinear of pin.The three-prong of BS1363 plug has the cross section of essentially rectangular, and its longitudinal axis is substantially perpendicular to a pair of line of pin down that forms summit under the isosceles triangle.Should be for what hold the BS1363 plug to following pin, the size of the contact apertures of second receptacle area is set at a pair of pin down shown in the row 13 among the reception table B.Similarly, the size in upper contact head hole also is set at the last pin that receives this plug.Similarly, the BS546 plug comprises that the cross section is the pin of circular, and the size respective settings of contact apertures is for preferably holding the pin of these three circular in the tight fit mode.
First receptacle area is suitable for receiving the various plugs that are referred to as 1 type plug, has listed embodiment in first hurdle of Table A.More particularly, 1 type plug comprises that the cross section is a pair of substantially parallel pin of circular.As embodiment easily, the size of the following contact apertures of this first receptacle area be set at can be under the press contacts effect of the elastic metallic contact below the contact apertures with the tight fit mode receive diameter at 3.7mm to the circular pin between the 5.1mm.Certainly, the diameter range for the treatment of the pin that received by following hole can change according to purposes separately and is without loss of generality.Typical 1 type plug has been shown in second hurdle of Table A, and it comprises the plug of conform European standard EN50075, Spain standard SEV 1011, Unificazione Italian CEI23-16, Scandinavia standard C EE7.Also, shown in as directed regional 1, in the middle of described a pair of contact apertures down, be provided with a pair of optional circular port in order to cater to 1 type plug with the 3rd circular pin.More particularly, this comprises and first circular port of described a pair of contact apertures conllinear down and second circular port of setovering from the line in these two following holes optional rounded contact hole.The first optional circular port of embarking on journey with described a pair of down hole is configured to receive the three-prong of the plug (the Italian CEI23-16 plug that for example, has three contact pins) of counter structure.Equally, the middle contact apertures of biasing is used to receive the biasing pin of Switzerland's plug/Spain plug SEV 1011.Put it briefly, the size of the following contact receptacle of first receptacle area is suitable for receiving the plug of the pin with circular section shape and size, and comprises that the plug of the pin of one or more non-circular cross sectional shape is suitable for second receptacle area.By second receptacle area is distributed to the plug that comprises one or more non-circular pins, treat that the variation of the pin that received by a pair of down jack of second receptacle area is less, thereby the safe contact mechanism that pin is had tighter resilient clamp can be provided.
Referring again to Fig. 1, Figure 1A and Fig. 3, first receptacle area and second receptacle area are arranged such that the isosceles triangle that is formed by corresponding contact apertures forms mutual inverted relation.More particularly, form trapezoidal summit basically with the corresponding summit of the following contact receptacle of this two couple, this to the last summit of isosceles triangle toward each other.The structure of Fig. 3 presentation graphs 1 is as the application of wall socket, and wherein the front casing mounting panel is made by durable plastic material.
In Fig. 2, Fig. 2 A and Fig. 4, first receptacle area and second receptacle area are arranged such that the also relative to each other inversion of a pair of isosceles triangle that is formed by the respective contacts jack.In this structure, first receptacle area (comprising 211,212 and 213) is arranged on a pair of down contact receptacle 221,222 and the 3rd of second receptacle area in the middle of the jack 223 fully.Although still be arranged on the trapezoidal summit by two pairs of following jacks 221,222 and 211,212 four summits that form, but trapezoidal size reduces greatly, this has formed compacter design, thereby makes the size of occupied effective area of whole contact receptacle and common single standard socket basic identical.Similarly, the structure of the blanket socket of Fig. 2 and Fig. 2 A is implemented as the exemplary embodiment of the wall socket shown in Fig. 4.Although two receptacle area are arranged to two pairs of inverted isosceles triangles, it should be understood that not being essential arranges that so these two triangles can be arranged to parallel construction.
It will be understood by those of skill in the art that because the hole dimension of the following contact receptacle 121,122 of second receptacle area is bigger a pair of pin down of 1 type plug can insert in it.
For the plug of eliminating type of error inserts the risk of second receptacle area, protective device is set.Because second receptacle area the best caters to the 2 type plugs that comprise two pin plug and three-prong plug, therefore comprise common closed three contact apertures but traditional fence gate type guard block of the insulation fence gate when rigid column is inserted the 3rd contact receptacle, opened and improper.
With reference to Fig. 5, Fig. 5 A and Fig. 5 B, described protective device comprises the first fence gate sub-component 320 and the second fence gate sub-component 340, and they form fence gate assembly 300 together.Fence gate assembly 300 comprises a plurality of insulated gate parts that can move between make position and open position.In make position, the insulated gate parts be positioned at contact apertures under, and at open position, the insulated gate parts get out of the way contact apertures, thereby can be from the outside near the contact mechanism of contact apertures below.The fence gate assembly is under the spring bias effect, thereby by spring thrust the grid parts is in the close position usually.Use a plurality of helical springs 350 as embodiment.The first fence gate sub-component 320 comprises that by the molded rigid body that forms of durable plastic material this rigid body has a pair of wing grid parts 322,324 that are symmetrically formed about central axial line 326.The first fence gate sub-component can axially moving with respect to the second fence gate sub-component between open position and make position along central axial line 326.In make position, described a pair of wing grid parts be positioned at second receptacle area following contact apertures under, and at open position, a pair of pin that described grid parts are removed with the plug that allows second type from the described a pair of contact apertures down of second receptacle area inserts.
Each wing grid parts of the first fence gate sub-component 320 are axially tapered along central axial line, thereby a pair of pin that drops on the plug on the grid parts when projection is when grid parts 322,324 insert, described taper meeting makes the grid parts be pushed along central axial line 326 axial directions, thereby opens contact apertures.In this preferred implementation, as more high-visible in Fig. 8 D, described taper is towards the axial end portion near the 3rd contact receptacle of second receptacle area of grid parts.Arrange spring assembly at far-end (that is), thereby can form the spring bias voltage towards distal movement when opening contact apertures when the grid parts, the grid parts are returned towards make position away from the end of tapering point.
As shown in Figure 5, by the axial projections 328 that is formed on grid parts far-end the appropriate location is installed and remained on to helical spring.The lateral dimension of wing grid parts (that is width) is suitable for making the maximum transversal scope of wing grid parts consistent with the maximum magnitude of a pair of contact pin down of two pin two type plugs.By this structure, because the lateral extent of two pin one type plugs falls within outside the maximum transversal scope of described a pair of wing grid parts of this first fence gate sub-component, thereby two pins of 1 type circular columns can not act on conical region and promote the grid parts towards open position.In addition, the shape and size of described a pair of wing grid parts are also set for and are made these two pins of 1 type plug can not act on these two conical regions of grid parts.Therefore, described a pair of grid parts can not be opened by two pin one type plugs.
As additional security measure, the first fence gate sub-component 320 also provides and for example alleviates because single post inserts the risk of the imbalance insertion that causes in one of them following contact receptacle of second receptacle area.This is by following realization, that is: at vertical two end supports first grid assembly of central axial line 326, thereby when being subjected to uneven insertion force, described a pair of grid parts can pivot to central axial line 326 tops, as among Fig. 8 A to Fig. 8 D more specifically shown in.In addition, it is asymmetric or tilt to insert risk in the socket that this layout of first grid assembly has also alleviated two pins.Therefore, except that moving to axial with respect to the second fence gate sub-component, the first fence gate sub-component also can pivot with respect to the second fence gate sub-component around the longitudinal axis of the line " E " in Figure 1A basically.The second fence gate sub-component comprises the forked parts of also being made by durable plastic material, forms first grid parts 342 in a side of fork, forms the grid parts 344,346 of a pair of bifurcated at opposite side, and they extend along the direction opposite with first grid parts 342.Similar with the first fence gate sub-component, the second fence gate sub-component also can move between make position and open position.The grid parts of this second fence gate sub-component under normal circumstances are positioned at three contact apertures belows of second receptacle area, thereby combine with the first fence gate sub-component, unless and up to inserting suitable plug, three contact apertures of all of second receptacle area all are closed.
The 3rd contact receptacle (earth terminal) by second receptacle area can be near the first grid parts 342 of the described second fence gate sub-component, and these grid parts roughly extend axially away from described a pair of forked grid parts.First grid parts 342 are also tapered towards its free end, as Fig. 5 A and Fig. 5 B more specifically shown in.By this pyramidal structure, when the three-prong of 2 type plugs inserts the 3rd contact apertures, three-prong promote towards the downward insertion meeting of tapering point towards open position the second fence gate sub-component (as among Fig. 6 more specifically shown in), thereby open whole sub-component and allow plug to insert.Shown in Fig. 5, Fig. 5 A and Fig. 5 B, the first fence gate sub-component is enclosed between the described a pair of forked parts, the second fence gate sub-component also can promote the first fence gate sub-component towards open position towards the open position motion, thereby the antagonistic spring bias voltage is opened all three contact apertures.In addition because described a pair of forked parts are not tapered, when with this to the corresponding a pair of circular pin of the footprint of forked parts when this inserts forked grid parts, the 3rd post that if there is no acts on the taper first grid parts just can not produce sliding motion.
As shown in Figure 7, when having a pair of plug with the corresponding a pair of down pin of 2 type plugs when inserting, the described a pair of pin parts down of two pin two type plugs can promote the first fence gate sub-component towards open position, and that the second fence gate sub-component keeps is motionless.Fig. 8, Fig. 8 A and Fig. 8 B show when being subjected to uneven insertion force with various views, and the first fence gate sub-component is with respect to the pivoting action of the jack housing and the second fence gate sub-component.
Fig. 9 and Fig. 9 A show the situation when a coupled columns of two pin one type plugs inserts second receptacle area.Because the footprint of 1 type pin is positioned at outside the maximum transversal scope of wing grid parts of the first fence gate sub-component, this is positioned on the forked parts the pin part, lacks the driving for one of them taper grid parts of grid parts, and the grid parts remain closed.Although with reference to comprising that the blanket socket of first receptacle area and second receptacle area described above-mentioned protective device, it should be understood that this protective device can be applicable to only to have in the blanket socket of second receptacle area and is without loss of generality.
