Background technology

When global tourism and trade increasingly increase, such change-over plug for travel is just more and more used Or travelling converter.It is therefore desirable to the travelling of the power outlet for being suitable for some various criterions that is small-sized, being easy to carry about with one turns Insert head.

Chinese patent application CN 101872911A disclose a kind of travelling converter with substantially round housing.Power supply Plug is placed in the enclosure interior and can remove the housing.In this way, it is possible to use at least three kinds different types of Attaching plug.Required attaching plug can be selected at relative lower housing section rotatable top shell part.The upper housing portion Dividing has a driving sliding block outwardly.The driving sliding block can be made to engage each attaching plug element.Therefore, being revolved The position above the attaching plug is gone to, and when the position to the attaching plug is rotated, the power supply is inserted Head will be removed from the housing.

The change-over plug for travel has many purposes.But, relatively described lower housing section machinery rotatable top shell part Accurate housing production process is needed, to allow the rotary motion of lower resistance and guarantee reliably to make the driving sliding block exist Each shell position engages attaching plug element.Additionally, circle is also in itself a kind of limitation.In many cases, for example, block Change-over plug for travel perhaps can be considered as easily to transport.Also, on circular change-over plug for travel, it is impossible to from a certain Angle sees all selectable attaching plug elements.

The 920B4 of German patent DE 10 2,011 014 discloses another change-over plug for travel, and it is referred to as " general turn Insert head ".In this change-over plug for travel, multigroup pin is provided with external shell.Every group of pin connects a control element, Can be mobile from outside by every group of pin described in those control elements.Guide the control unit on the housing by chute Part.The control element is guided using the baffle plate being arranged in external shell additionally.The baffle plate has guide rail, and The control element can pass through groove thereon.The guide rail provides upper end position and lower end position.To baffle plate elasticity Ground prestress, so that control element can be firmly held in the upper end position or lower end position.The control element and right The pin group answered can be discharged from the end position, and be moved up or down, because except the startup control The selector for being also disposed at outside is also started outside element.Pressing the selector can move the baffle plate confrontation spring force.With This method, can from it or lower end position is shifted out by using control element pin.

In this scheme, outside control element is both used to be moved to pin group from first end position (standby position) The second end position (uses position), is additionally operable to lock those pin groups in these positions.Its drawback for existing is to make Selector also necessarily be in running status during moving pin group with control element.Comfortable singlehanded behaviour can not thus be carried out Make.Additionally, the control unit can not be moved freely in the chute, because flexibly pre-add should in moving process The baffle plate of power continuously extrudes the control element always.And when the selector is operated, faulty operation can also make two groups to insert Pin is moved to and used on position, or is at least moved towards using position.

The content of the invention

The purpose of this utility model be to provide it is a kind of avoid it is of the prior art deficiency improved travelling converter.The trip Row converter cost-effective and should be able to be manufactured reliably, it is easy to transport and operation, and electricity aspect is very safe.

Change-over plug for travel of the present utility model has housing, and the housing can have variously-shaped.For example, generally, it is block It is very practical for transport.But, the function mode of change-over plug for travel of the present utility model is designed to can be in very great Cheng The shape of unrestricted choice housing on degree.It is favourable, but running of the present utility model when housing has at least one flat face Mode is also suitable for the surface of shell of bending.The housing can include one or more pieces.It has been proved that the housing includes two parts It is useful, specifically lower housing section and upper case portion.It is removably connected to each other, for example, use Mechanical means, is useful using mode connects for screw.

The housing should have at least one socket.The socket is effectively arranged on the housing upper face.The socket can With different shapes, this depends on the type of the attaching plug to be assigned thereon (hereinafter referred " plug ").For example, such as Schuko plugs are really assigned on the socket, then just there is substantially cylindrical sunk part on the socket, additionally had Female joint (female connector) for assigning the Schuko plugs.For other kinds of plug, it is not necessary to have Depression or groove.It is useful to set flat upper casing dignity, and multiple female joint (female contact) can be set on the face. Generally, at least two female joints should be set, and it forms the female joint pair for assigning standard plug.In order to assign multiple not With the plug of standard, multiple female joints are set to being useful.If plug also has earth conductor, and socket meaning will be carried For the chance being grounded, generally, the 3rd female joint is set, or the 3rd joint is provided according to the plug to be assigned, be also necessary 's.

The change-over plug for travel should also have the plug of at least one first standards and the second plug of the second standard. (these plugs are also sometimes referred to as " plug-in type pin group (plug-in pin sets) ").The plug of first standard can be with It is, for example EU European plugs that the plug of the second standard can be the American plugs of US.These plugs can have two pins, i.e. it It is earth-free；Or, they can have three pins, to provide grounding pin.Therefore, change-over plug for travel of the present utility model It is suitable to be used in more than one country.

Usefully, in general, it is also necessary first plug and second plug select one and use.Institute State change-over plug for travel and may also include three or more plugs.It has been proved that with the three or four travelling conversions of plug Plug is highly useful.At least one of which plug (but typically all of plug) can by from standby position (in this position, Plug is placed in housing substantially) move to using on position.Position is being used, plug is placed in completely or at least partially usablely Outside housing.Regularly, when plug is back to standby position, plug can be moved back in housing completely.Plug can be moved back in housing As far as its without prejudice to, other plugs are useful enough.

First plug is connected with a driving sliding block, and the driving sliding block is used to move first plug from standby position To using position.Second plug is also connected with a driving sliding block, and it is used to move to the second plug from standby position and uses Position.Therefore, the change-over plug for travel at least has first to drive sliding block and second to drive sliding block.Those driving sliding blocks can have Button-like mode is designed to effect, to make it easier to be moved with a finger.In order to house the driving sliding block, can be on housing Chute is set.Those chutes can also be connected with each other to form the guide rail for the driving sliding block.In general, it is each drive Movable slider all sets a chute, and these chutes are arranged parallel to each other, and is useful.

Slide selector can be set on the change-over plug for travel, the slide selector can at least be moved to first position And the second place.In its first position, the slide selector discharges first plug；Or, in its second place, the slip Selector discharges the second plug, thus, it is possible to first plug or the second plug are alternatively moved to using on position.

In this way, the slide selector provides the additional advantage of practicality for the change-over plug for travel.By trip Row changeover plug band to same destination country is not repeatedly uncommon.A destination country by required plug at it By it from standby position is moved back to using position it is also very common when being not needed.Therefore, when can it is described slide choosing It is highly advantageous to select when adjusted on device corresponding type of plug.It is very simple that the slide selector is marked, can Understand destination country easily to distinguish and can be adjusted thereon.Once the slide selector is moved on appropriate location, then only Having corresponding plug can be moved to using on position.Generally, it means that be only possible to mobile driving sliding block.

Due to change-over plug for travel should always be configured to it is compacter, therefore, it is described driving sliding block be generally within close proximity each other. So, such as finger is not precisely placed to drive on sliding block will inadvertently while the neighbouring driving sliding block of movement Situation will be easy to occur.However, only allowing to drive a plug due to the utility model, thus (usual) is also only allowed A driving sliding block is driven, (or it will not at least move related inserting so the driving sliding block that touches of imprudence will not be moved Head).This can make the operation of the change-over plug for travel become more fault-tolerant.

However, setting, a plug and a slide selector for driving sliding block can only be discharged also with important security Advantage.If removing more than one plug simultaneously, then electric current will be flowed by those joints for being not used to this standard. Can so damage change-over plug for travel, it is the worst in the case of, can also damage connected equipment, or even wound is caused to user Evil.

The plug can be moved to using on position using the driving sliding block.For the safe handling of change-over plug for travel For, even if when the plug counter pressure inserts power outlet, it is remained at using being critically important on position.At this In the system of utility model, settable stop or locking member are hindered with ensuring that the plug is maintained at using on position and by them Terminate in this.The locking member can prevent at least one plug of the change-over plug for travel；The locking member can also be effectively Multiple or all of plug is prevented using on position.

Usefully, the locking member is designed as the part independently of the slide selector.As the reality of individual components It has the advantage on producing to apply mode.The slide selector is need not to transmit or undergo part more energetically.However, due to The property of its own, the locking member must apply enough power and is maintained at using on position with by the plug of every kind of standard.

It is useful when the locking member is also independently of the part of the driving sliding block based on the reason for similar. In the case, when the locking member has at least one part for being not belonging to the slide selector or driving sliding block During part, the locking member should be construed as individual components.Generally, when whole parts of the locking member are designed to both Independently of the part of the slide selector, but independently of it is described driving sliding block part when, be useful.

It is useful when the locking member (if there is provided if) Connection Release button, the release button is arranged at shell External body is simultaneously driven along release direction.When by a plug by being moved back to standby position using position, such release button can Make the locking member directly perceived and safely discharge.Such design is compared with those by driving sliding block or slide selector, even inserting Some designs of motion to discharge plug of head itself seem safer, also more reliable.So that the release button will not be by nothing Driven between meaning, it can also be for example red equipped with warning indicator or design warning coloration.The release button can be the one of housing Part, for example, when that can be pressed due to suitably designing a part for the housing.Generally, a recess is set on housing And the release button is set in this recess used as the part independently of housing, it is useful.Usefully, the release button can It is positioned opposite with the slide selector and/or the driving sliding block.

Against the release direction, to the locking member, flexibly prestress is (typically：Spring biasing) it is useful 's.To the locking member, flexibly prestress can make the plug reliably be snapped in locking shape using position once entrance State.When the spring is accurately acted against the release direction, it is also advantageous in mechanical aspects.

One effective embodiment of the locking member is that the locking member has at least one locking supporting leg, and the lock Determining supporting leg has sliding surface and locking projections.The element being connected by mobile plug with one can be slided on the sliding surface.Afterwards The element may be stuck at the locking projections, to lock the plug being connected with the element.

Such change-over plug for travel is useful：Its at least one plug have slide protrusion or mechanically with it is such Slide protrusion is firmly connected, and the slide protrusion runs and can be presented in the locking projections on the sliding surface Lock-out state.

Such change-over plug for travel is also useful：Its locking mechanism has multiple locking supporting legs, such as 2,3 or 4 locking supporting legs.The quantity of the locking supporting leg is identical with the quantity of plug.When the quantity of the locking supporting leg is less than slotting It is also useful and enough during the quantity of head.

Especially later in the case of, when at least two plugs each of be connected with slide protrusion, and the two Slide protrusion is useful when all being run on the same locking supporting leg of the locking member.Because the two slide protrusions exist Run on same locking supporting leg, therefore, this means that the two slide protrusions in same sliding surface and same locking projections Run on (two slide protrusions can thereon be presented lock-out state).Because two plugs on the change-over plug for travel are not Can be simultaneously displaced using on position, so the slide protrusion can alternatively be presented this locking shape in the locking projections State.If however, two slide protrusions, such as two slide protrusions of adjacent header, share a size and suitably lock branch If leg, then the quantity of locking supporting leg can be reduced, thus the change-over plug for travel can be configured to more succinct.

Under background of the present utility model, the slide selector can be set to any suitable form.In general, its Mechanically should only allow a plug to move and suppress other plugs to move.Usefully, the slide selector may act on institute Driving sliding block is stated, each drives sliding block to be connected with certain plug.And work as the slide selector and act on and the plug phase It is also useful during another element for connecting.

The slide selector can have slide selector body, and the slide selector body is placed in the travelling conversion Inside plug casing.In addition it is useful that a groove is set on housing, and the groove can make to grasp the slide selector Make.For example, an activation button (hereinafter also referred to " slide selector button ") can be used by the groove.The slide selector Body can also be placed in housing outside, be that this acts on the driving sliding block outside housing, or be this by a through hole Internally act on the driving sliding block.

At least one plug or whole plugs can connect a joint element, and the joint element cooperates with the slide selector To prevent the plug from moving to using on position.Usefully, the joint element may be designed as a projection or substantially convex Rise.The motion of the joint element can be prevented by a catch elements of the slide selector, for example, hindered by card article, card convex etc. Only.Those card convexs are effectively continuously arranged, so that those card convexs form the cassette tape (blocking strip) of pectination.According to selection The position of element, can not also prevent the motion of joint element, but allow it to pass through.Therefore, advantageously, the locking unit Part can have the groove that multiple can pass through the joint element.For example, can set a series of in the slide selector Raised and depression.

It is useful when having chute on the housing of the change-over plug for travel.The driving sliding block can be in these chutes Interior operation.A chute is may also set up in the slide selector.These chutes can be such that sliding block is moved while being directed to. Therefore, it embodies a kind of favourable and efficient mechanical conceptual of cost.Due to setting multiple drive generally on change-over plug for travel Movable slider, so being particularly advantageous when multiple driving sliding blocks can be guided in the chute in a simple manner. It is in background of the present utility model, described to drive the sliding block only to cause the motion of the plug, typically up and down Motion.Need not be locked in for the plug and use on position by the driving sliding block, need not also ensure that once only may be selected one inserts Head.Because the driving sliding block in the utility model background is only allowed a kind of function of execution, it is possible to easily and reliably exist It is guided in chute.If for example, loading onto spring to the driving sliding block, then it is guided just in chute Not so good use can be become, this is often as such sliding block and tends to incline, and is run meeting " as hook ", just has certainly Bigger resistance.

As already described, it is have when cannot again change the position of selection element when plug one is moved to using on position Profit.Therefore, a latch component can be provided.The latch component is effectively arranged in the slide selector or coupled. Latch component and slide selector can be a global facility or at least one connected whole parts.

With the first function element for being cooperated with first plug and for cooperated with second plug The latch component of two function element is useful.In order that the latch component is simple to manufacture and calculates, when first function Element and the second function element are useful when constructing in the same manner.First function element and the second function element can be all Obtained from identical component or similar components.

It is special when the latch component has can be bonded on the finger in consolidating the receiver member being connected with housing It is not useful.The function element can effectively be designed to finger form.The latch component can also have raised or convex Block, rather than finger.The receiver member may be configured to, such as raised or recessed on breech lock guide member (latch guide) Fall into.The receiver member can be also configured to groove or hole on the part that is connected on housing or with housing.

It is useful when the latch component includes spring element.The latch component even can all by a spring Element is formed, for example, formed by plane spring (flat spring) (or flat spring).Such spring can be used to the breech lock The flexibly prestress of the finger of element.The direction of spring force is directed to the receiver member on housing.As long as all All on standby position, then the spring will be prevented from advancing by leaps and bounds in corresponding receiver member plug.

When plug one is moved to using on position, a finger of the latch component is just at once towards the spring Elastic force is pressed into when in a groove, is favourable.

When the spring element of the latch component is in the storage unit for accommodating the finger and being connected with housing It is useful when flexibly preloading its finger on the direction of part.Afterwards, as long as plug is on standby position, so that it may make The finger is effectively prevented to be bonded in corresponding receiver member with the element connected with the stabilizing plugs.For example, working as It is useful when the part of the driving sliding block undertakes this work.For example, the driving sliding block can connect the sliding surface, when The driving sliding block is moved to during using on position, the sliding surface is slided in the finger, but when the driving sliding block During in using on position, the sliding surface then discharges the finger and drives the finger of sliding block to fall into distribution so as to distribute to To in the groove of the finger.

Other features of the present utility model and advantage can be obtained from following accompanying drawing and its associated description.With reference to diagram and Its associated description is described to feature of the present utility model.However, these features can also be included in the utility model theme Other combination in.Therefore, disclosed each feature is it will be also be appreciated that be disclosed in combine rational with other feature technologies.

In another side view, Fig. 7 shows the cooperation relation of known elements in Fig. 5 and Fig. 6.In the figure 7, again can be with It is seen in the lower housing section 14 and slide selector body 44 of its appropriate location in complete change-over plug for travel.Slide The back side of selector body 44 engages with the guid arm 50 of the described second driving sliding block.At its back side, the slide selector sheet Body has multiple card convexs, card convex 48A, 48B, 48C, 48D and 48E.Groove (groove 54A, 54B, 54C are provided between each card convex And 54D) form passage.Although in position shown in the figure, card convex 48C is engaged with the engagement protrusion of guid arm 50, When the slide selector body is in another location, the engagement protrusion of guid arm 50 is just no longer engaged with card convex.Conversely, moving Holding slide selector body 44 can make the card convex 48 of the guid arm be placed in groove top.Thus position, can be towards using position Put and move down the guid arm and and then entirely drive sliding block.

Fig. 8 is the side view similar with Fig. 6, but in this figure, depicts an extra part.Under being for showing again Housing parts 14, second drive sliding block 24 and slide selector body 44.Above illustrate, driven sliding block 24 (also like other Driving sliding block is the same) there is guid arm 50.In its end, guid arm 50 has engagement protrusion 52, and it can be caused and card convex 48 Engagement.

In addition to already shown part in Fig. 6 and Fig. 7, latch component 56 has also been shown in this view.Breech lock The substantially shape with flat spring of element 56, the inside of its laminating slide selector body 44 is (towards the side of the guid arm Face).Hold thereon, latch component 56 has the finger 58 stretched out and slide the top of selection body 44.The latch component also has Pressure-bearing surface 60, it is also comprising a height (elevation).

The function mode of latch component 56 is as follows.When driving sliding block 24 to be located at the upper position for showing, engagement protrusion 52 Pressure is applied to pressure-bearing surface 60.When slide selector body 44 is located at appropriate position, one moves down the driving sliding block, Engagement protrusion 52 (or, if necessary, another component of guid arm 50) just no longer extrude pressure-bearing surface 60.To finger 58 flexibly Prestress, so that it is due to spring force towards the center movement (being moved to the left side in Fig. 8) of change-over plug for travel.

Once being applied on pressure-bearing surface 60 there is no pressure, the elastic force will produce effect, finger 58 will be moved to On position latching.In this position latching, the finger is engageable to fixedly positioning the element being connected with housing, and the element generally may be used It is described as finger receiver member.Slide selector body 44 can be so caused to be also held at the position fixed relative to housing Put.

Fig. 9 is the stereogram of slide selector body 44 and latch component 56 (or, being more accurately its finger 58). Latch component 56 can be fabricated by by the flat spring of such as bending.The upper end of slide selector body 44 has recess.Breech lock unit The finger 58 of part 56 can be inserted by four recesses for showing.First, which ensure that latch component 56 and slide selector Body 44 is also connected well each other in upper area；Secondly, these recesses make four finger 58A of latch component 56, Movement is possibly realized after 58B, 58C and 58D come between position latching and selection position (or standby position).

Figure 10 is the stereogram of the other direction of slide selector body 44 and latch component 56, again can be with from the figure It is one can easily see finger 58 and its function mode.Latch component 56 should firmly mechanically connect slide selector body 44. Therefore, slide selector body 44 can have can to make company is easily inserted or engaged between slide selector body 44 and latch component 56 The groove for connecing.The contents of the section can be seen from the bottom of slide selector body 44.

Figure 11 depicts the cooperation relation between latch component 56 and upper case portion 12 in bottom view.The view direction It is the bottom that upper case portion 12 is pointed to from lower housing section 14, it is possible to see female joint 18.Before latch component 56 is close to Shell wall；In feature change-over plug for travel, it is also kept by slide selector body 44, however, for visual simplification, Slide selector body 44 is not shown herein.

Finger 58A, 58B of latch component 56,58C and 58D laminating housings upside.All fingers are showd that in awaiting orders On position.The driving sliding block and corresponding plug one associated with finger are moved into and use position, and the finger just moves into breech lock position Put.In order to the finger is locked on the position latching, locking gathering sill 62 is provided with the downside of housing.The locking gathering sill With groove.In the embodiment being shown in which, the groove is separated with adjacent grooves by rod.Locking gathering sill 62 has four Individual groove：Groove 64A, groove 64B, groove 64C and groove 64D.

The locking gathering sill of other multi-forms can also be useful；Generally, the locking gathering sill should have phase To the finger receiving element of housing firm position.Finger 58 1 enters groove 64 associated with it, and latch component 56 is in just The state of an existing relative housing firm position.Thus, the latch component just can not be moved with slide selector body 44 again It is dynamic；This up and descending movement on view direction all can be blocked.

Figure 12 is the perspective view of two other part for cooperating of the change-over plug for travel.Two parts also all show Under for its " nature " position, i.e. it is presented on the position in complete change-over plug for travel.What is shown is lower housing section 14 And locking member 66.In a known manner, the lower housing section has four chutes 42 parallel to each other.Locking member 66 With known release button 40.Locking member 66 also has framework 68.On framework 68 equipped with can make locking member 66 with it is described The fixation clamp (not described in detail to it) that the miscellaneous part of change-over plug for travel is connected.Locking member 66 also has three locks Determine supporting leg：First locking supporting leg 70A, the second locking supporting leg 70B and the 3rd locking supporting leg 70C.

Figure 13 illustrates how the locking supporting leg operates.In the figure, locking member 66 not with lower housing section 14 show together, and are shown together with the header body 32 for European plugs.Locking member 66 also with other header bodies and Haptic element cooperates, but the function of locking supporting leg is retouched with the example of European plugs and corresponding plug body 32 only herein State.The header body is firmly connected with the first driving sliding block 22, and first drives sliding block 22 with guid arm 50.Header body 32 is also Connection slide protrusion 72.The slide protrusion can be slided and in the lower end of the first locking supporting leg 70A along the first locking supporting leg 70A Lock-out state is presented.

Figure 14 shows the part in Figure 13, but is shown in the way of side view, can be more preferable from this view See accurate function mode.In this view, it can be seen that the first locking supporting leg 70A (the same also like other locking supporting legs) With sliding surface 74 and locking projections 76.The slide protrusion 72 of header body 32 can be slided on sliding surface 74.In order to start The slip, locking member 66 can transverse shifting, you can (figure is moved in the release direction limited by the direction of release button 40 In direction from right to left).To the flexibly prestress of locking member 66, so that the extruding sliding surface 74 of slide protrusion 72.When slotting Head body 32 reaches it and uses when on position, and slide protrusion 72 reaches locking projections 76.Due to flexibly pre- to locking member 66 Plus stress (so that, in this figure, therefore it be pressed towards right), thus slide protrusion 72 can move on to the lower section of locking projections 76 simultaneously Thus it is stopped.This prevention is mechanically very favorable, because along the principal spread direction of locking supporting leg 70A to this Locking supporting leg is loaded, and thus locking supporting leg 70A substantially need to only absorb compression stress.However, by pressing release button 40, This stop can be positively discharged, also, the header body can be moved back on its standby position along sliding surface 74.

In the way of more specifically being described in be broadly described and accompanying drawing, can production operation as snug as a bug in a rug and hardly There is the travelling converter that operating mistake occurs.However, interestingly, the travelling converter and inexpensive is produced, even and if big Be must be allowed in batch production it is larger it is fault-tolerant in the case of, it is also possible to it is cheap and reliably produce the travelling converter.
