Description

The change-over plug for travel of safety

Technical field

The present invention relates to a kind of change-over plug for travel, it is also referred to as " travelling converter " herein.Using this converter, The attaching plug of a certain (country) standard can be inserted into the power outlet of Reiseziel.For this purpose, the travelling conversion plug Head needs the socket of the first standard and the attaching plug of another standard.In this application, more precisely, be related to it is a kind of can insert Enter the change-over plug for travel of at least power outlet of the first standard and the second standard.In addition, can in the change-over plug for travel To select an attaching plug for using the first standard and the second standard.

Background technique

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 which the travelling of the power outlet for being suitable for several various criterions that is small-sized, being easy to carry about with one turns Insert head.

101872911 A of Chinese patent application CN discloses a kind of travelling converter with substantially round shell.Power supply Plug is placed in the enclosure interior and can remove the shell.In this way, can be used at least three kinds it is different types of Attaching plug.It can choose required attaching plug at opposite lower housing section rotatable top shell part.The upper housing portion Dividing has an outwardly projecting driving sliding block.The driving sliding block can be made to engage each attaching plug element.For this purpose, being revolved Go to the position above the attaching plug, and when being rotated to position below the attaching plug, the power supply is inserted Head will be removed from the shell.

The change-over plug for travel has many purposes.But the relatively described lower housing section machinery rotatable top shell part Accurate shell production process is needed, to allow the rotary motion of lower resistance and guarantee that the driving sliding block is reliably made to exist Each shell position engages attaching plug element.In addition, round itself is also a kind of limitation.In many cases, for example, it is blocky Change-over plug for travel perhaps can be considered as more easily transporting.It, cannot be from a certain also, on round change-over plug for travel Angle sees all selectable attaching plug elements.

10 2,011 014 920 B4 of German patent DE discloses another change-over plug for travel, is referred to as " general turn Insert head ".In this change-over plug for travel, multiple groups pin is provided in external shell.Every group of pin connects a control element, It can be mobile from outside by every group of pin described in those control elements.Guide the control member on the housing by sliding slot Part.Additionally the control element is guided using the baffle being arranged in external shell.The baffle has guide rail, and The control element can pass through groove thereon.The guide rail provides upper end position and lower end position.To the baffle 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 released from the end position, and be moved up or down, this is because except the control is started The selector for being also disposed at outside is also started outside element.The baffle confrontation spring force can be moved by pressing the selector.With This method, can be from thereon or lower end position is shifted out by using control element pin.

In this scheme, external control element had both been used to for pin group being moved to from the first end position (standby position) The second end position (uses position), is also used to lock those pin groups in these positions.Its existing drawback is to make Operating status necessarily also is in selector during the mobile pin group of control element.Comfortable singlehanded behaviour is not can be carried out thus Make.In addition, the control unit cannot move freely in the sliding slot, this is because flexibly pre-add is answered in moving process The baffle of power continuously squeezes always the control element.And when operating the selector, faulty operation can also make two groups to insert Foot is moved to using on position, or at least towards using position mobile.

Summary of the invention

The object of the present invention is to provide one kind to avoid insufficient improved travelling converter in the prior art.The travelling turns Parallel operation should be able to save cost and reliably be manufactured, and be easy to transport and operate, and electricity aspect is very safe.

Change-over plug for travel of the invention has shell, which can have various shape.For example, in general, bulk is to fortune It is very practical for defeated.But the function mode of change-over plug for travel of the invention be designed to can largely freely Select the shape of shell.It is advantageous when shell has at least one flat face, but function mode of the invention is also suitable for Curved surface of shell.The shell may include one or more pieces.It has been proved that it is useful, tool that the shell, which includes two parts, It is lower housing section and upper case portion for body.It is removably connected to each other, such as using mechanical means, is made It is useful with screw connection.

The shell 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 plug is assigned on the fruit socket, then just there is basically cylindrical depressed section on the socket, additionally have For assigning the female connector (female connector) of the Schuko plug.For other kinds of plug, do not need to have Recess or groove.It is useful, settable multiple female connectors (female contact) on the face that flat upper casing dignity, which is arranged,. In general, at least two female connectors should be arranged, the female connector pair for assigning standard plug is formed.In order to assign it is multiple not With the plug of standard, multiple female connectors are set to being useful.If plug also has earth conductor, and socket meaning will mention For the chance of ground connection, in general, setting third female connector, or the plug to be assigned of foundation provide third connector, and necessary 's.

The change-over plug for travel should also have the plug of at least one the first standard 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, such as EU European plugs that the plug of the second standard can be the American plug of US.These plugs can have there are two pin, that is, it It is earth-free；Alternatively, they can have, there are three pins, to provide grounding pin.Therefore, change-over plug for travel of the invention is suitable for It is used in more than one country.

Usefully, in general, select one using being also necessary to first plug and second plug.Institute Stating change-over plug for travel may also include three or more plugs.It has been proved that band there are three or four plugs travelling conversion Plug is highly useful.At least one of which plug (but usually all plugs) can by from standby position (in this position, Plug is placed in shell substantially) it is moved to using on position.Position is being used, plug is placed in completely or at least partially usablely Outside shell.Regularly, when plug is back to standby position, plug can be moved back in shell completely.Plug can be moved back in shell It is useful for not interfering other plugs as far as it enough.

First plug is connect with a driving sliding block, which is used to move first plug from standby position To using position.Second plug is also connect with a driving sliding block, is used to the second plug moving to use from standby position Position.Therefore, the change-over plug for travel at least has the first driving sliding block and the second driving sliding block.Those driving sliding blocks can have It is designed to button-like mode to effect, it is mobile with a finger to make it easier to.It, can be on shell in order to accommodate the driving sliding block Sliding slot is set.Those sliding slots can also be connected with each other to form the guide rail for the driving sliding block.It in general, is each drive A sliding slot is all arranged in movable slider, and these sliding slots are arranged parallel to each other, and is useful.

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

By this method, the slide selector provides the additional advantage of practicability for the change-over plug for travel.By trip It is not repeatedly uncommon that row changeover plug, which is brought to same destination country,.In a destination country by required plug at it It by it from using position to be moved back to standby position is also very common when being not needed.Therefore, when can be selected in the sliding It is highly advantageous for selecting when adjusting corresponding type of plug on device.It is very simple that the slide selector, which is marked, can Understand destination country easily to distinguish and can be adjusted on it.Once the slide selector moves on appropriate location, then only There is corresponding plug that can be moved to using on position.Usually, it means that be only possible to a mobile driving sliding block.

Due to change-over plug for travel should always be configured to it is compacter, the driving sliding block is usually within close proximity each other. So such as finger is not precisely placed to inadvertently move neighbouring driving sliding block on driving sliding block simultaneously The case where will be easy to occur.However, thus (usual) also only allows to drive since the present invention only allows to drive a plug One driving sliding block, so the driving sliding block accidentally touched will not move (or it will not at least move associated plug). This can make the operation of the change-over plug for travel become more fault-tolerant.

However, setting, which can only discharge a plug and the slide selector of a driving sliding block, also has important safety Advantage.If removing more than one plug simultaneously, electric current will be not used to the connector flowing of this standard by those. Change-over plug for travel can be damaged in this way, in the worst case, can also damage equipment connected to it, or even cause to hurt to user Evil.

The plug can be moved to using on position using the driving sliding block.Safe handling for change-over plug for travel For, even if remaining at when the plug counter pressure is inserted into power outlet using being critically important on position.At this In the system of invention, settable stop or locking member with ensure the plug be maintained at using on position and by they prevent in This.The locking member can prevent at least one plug of the change-over plug for travel；The locking member can also effectively will be more A or all plug is prevented using on position.

Usefully, the locking member is designed as the component independently of the slide selector.Reality as individual components Applying mode, it has the advantage in production.The slide selector is the component that need not be transmitted or be subjected to more energetically.However, due to The property of its own, the locking member must apply enough power being maintained at the plug of every kind of standard using on position.

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

When the locking member (if if being provided with) Connection Release button be it is useful, which is set to shell It is driven outside body and along release direction.When by a plug by using position to be moved back to standby position, such release button can Keep the locking member intuitive and safely discharges.Such design is compared with those by driving sliding block or slide selector, even slotting Certain movements of head itself seem safer to discharge the design of plug, also more reliable.So that the release button will not be by nothing It is driven between meaning, it can also be equipped with warning indicator or design warning coloration, such as red.The release button can be the one of shell Part, for example, when a part due to suitably designing the shell can be pressed.In general, a recess is arranged on shell And the release button is set in this recess as the part independently of shell, 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 (typically: spring biasing) is useful 's.To the locking member, flexibly prestress can make the plug be reliably caught 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.

The effective embodiment of the one of the locking member is that the locking member has at least one locking supporting leg, and the lock Supporting leg is determined with sliding surface and locking projections.It can be slided on the sliding surface with one by the element that mobile plug is connected.Later 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 securely connects, and the slide protrusion runs and can present in the locking projections on the sliding surface Lock state.

Such change-over plug for travel is also useful: its locking mechanism have 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 when the quantity of head.

Especially later in the case where, when each of at least two plug is connected with slide protrusion, and the two Slide protrusion is all useful when running on the same locking supporting leg of the locking member.Since the two slide protrusions exist It is run on same locking supporting leg, therefore, this means that the two slide protrusions in same sliding surface and same locking projections It is run on (lock state can be presented in two slide protrusions on it).Because two plugs on the change-over plug for travel are not It can be simultaneously displaced and use on position, so this locking shape can be alternatively presented in the slide protrusion in the locking projections State.However, if two slide protrusions, such as two slide protrusions of adjacent header, a shared size 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.

In the context of the present invention, the slide selector can be set to any suitable form.In general, mechanical On should only allow a plug to move and inhibit other plugs move.Usefully, the slide selector may act on the drive Movable slider, each driving sliding block are connected with certain plug.And it is connected when the slide selector is acted on the plug It is when another element and useful.

The slide selector can have slide selector ontology, which can be placed in the travelling conversion Inside plug casing.Furthermore be arranged on shell a groove be it is useful, which 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 Ontology can also be placed in outside the shell, act on the driving sliding block outside shell thus, or thus by a through-hole The driving sliding block is acted in inside.

At least one plug or whole plugs can connect a joint element, which cooperates with the slide selector To prevent the plug from being moved to using on position.Usefully, which may be designed as a convex block or substantially one convex It rises.The movement of the joint element can be prevented by a catch elements of the slide selector, such as be hindered by strip, 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 also should can not prevent the movement of joint element, but it is allowed to pass through.For this purpose, advantageously, the locking member Part can have multiple grooves for passing through the joint element.For example, can be arranged in the slide selector a series of Protrusion and recess.

It is useful when having sliding slot on the shell of the change-over plug for travel.The driving sliding block can be in these sliding slots Interior operation.It may also set up a sliding slot in the slide selector.These sliding slots can be such that sliding block is moved while being directed to. Therefore, a kind of advantageous and cost-effective mechanical conceptual is embodied.Since multiple drives being usually arranged on change-over plug for travel Movable slider, so being particularly advantageous when multiple driving sliding blocks can be guided in the sliding slot in a simple manner. In the background of the invention, the driving sliding block must only cause the movement of the plug, movement usually up and down. The plug need not be locked in using on position, need not also ensuring primary a plug only to may be selected by the driving sliding block.Cause It is only allowed for the driving sliding block in background of the present invention and executes a kind of function, it is possible to easily and reliably to it in sliding slot It is guided.For example, guiding in sliding slot to it will become less if loading onto spring to the driving sliding block Handy, this is often as such sliding block and tends to tilt, and runs meeting " as hook ", just has bigger resistance certainly Power.

It as already described, is to have when cannot change the position of selection element again when plug one is moved to using on position Benefit.Thus, it is possible to provide a latch component.The latch component is effectively arranged in the slide selector or coupled. Latch component and slide selector can be integral component or at least one connected whole parts.

With the first function element for cooperating with first plug and for cooperating with second plug The latch component of two function element is useful.In order to make the latch component be simple to manufacture and it is cost-effective, 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 It is obtained from identical component or similar components.

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

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

As soon as a finger of the latch component is at once towards the spring when plug is moved to using on position When elastic force is pressed into a groove, it is advantageous.

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

Other features of the invention and advantage can be obtained from following attached drawing and its associated description.In conjunction with diagram and its phase Description is closed feature of the invention is described.However, these features also may include in other combinations of present subject matter. Therefore, during disclosed each feature it will be also be appreciated that be disclosed in reasonably is combined on other feature technologies.Part diagram is slightly Simplification, and be schematical.

In another side view, Fig. 7 shows the cooperation relation of known elements in Fig. 5 and Fig. 6.It, again can be in Fig. 7 It is seen in the lower housing section 14 and slide selector ontology 44 of its appropriate location in complete change-over plug for travel.Sliding The back side of selector ontology 44 is engaged with the guid arm 50 of the 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 equipped between each card convex And 54D) form channel.Although in position shown in the figure, card convex 48C is engaged with the engagement protrusion of guid arm 50, When the slide selector ontology is in another location, the engagement protrusion of guid arm 50 is just no longer engaged with card convex.On the contrary, moving Holding slide selector ontology 44 can be such that the card convex 48 of the guid arm is placed in above a groove.Thus position, can be towards using position It sets and moves down the guid arm and entirely drive sliding block in turn.

Fig. 8 is the side view similar with Fig. 6, but in this figure, depicts an additional component.Under being shown again Housing parts 14, second drive sliding block 24 and slide selector ontology 44.Front has illustrated, and drives sliding block 24 (also like other Drive sliding block the same) there is guid arm 50.In its end, guid arm 50 has engagement protrusion 52, can be caused and card convex 48 Engagement.

Other than component already shown in Fig. 6 and Fig. 7, latch component 56 has also been shown in this view.Latch Element 56 substantially with the shape of flat spring, is bonded the inside (side towards the guid arm of slide selector ontology 44 Face).It holds on it, latch component 56 has the finger 58 for stretching out 44 top of sliding selection ontology.The latch component also has Pressure-bearing surface 60 also includes 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 shown, engagement protrusion 52 Pressure is applied to pressure-bearing surface 60.When slide selector ontology 44 is located at position appropriate, one moves down the driving sliding block, Engagement protrusion 52 (alternatively, when necessary, another component of guid arm 50) just no longer squeezes pressure-bearing surface 60.Flexibly to finger 58 Prestress, so that it is mobile (left side i.e. into Fig. 8 is mobile) towards the center of change-over plug for travel due to spring force.

Once there is no pressure to be applied on pressure-bearing surface 60, which will generate effect, and finger 58 will be moved to On latch position.In this latch position, the engageable element for fixedlying positioning connection with shell of the finger, which usually may be used It is described as finger receiver member.Slide selector ontology 44 can be caused to be also held at the position fixed relative to shell in this way It sets.

Fig. 9 is the perspective view of slide selector ontology 44 and latch component 56 (or, being more accurately its finger 58). Latch component 56 can be fabricated by for example curved flat spring.The upper end of slide selector ontology 44 has recess.Latch member The finger 58 of part 56 can be inserted by four recesses shown.Firstly, which ensure that latch component 56 and slide selector Ontology 44 is also connected in upper area well each other；Secondly, these recesses make four finger 58A of latch component 56, Movement is possibly realized after 58B, 58C and 58D come between latch position and selection position (or standby position).

Figure 10 is the perspective view of the other direction of slide selector ontology 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 ontology 44. For this purpose, slide selector ontology 44, which can have, can make that company is easily inserted or engaged between slide selector ontology 44 and latch component 56 The groove connect.The contents of the section can be seen from the lower part of slide selector ontology 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 directed toward from lower housing section 14, it is possible to see female connector 18.Before latch component 56 is close to Shell wall；In functional change-over plug for travel, also kept by slide selector ontology 44, however, for visual simplification, Slide selector ontology 44 is not shown herein.

On the upside of finger 58A, 58B, 58C and 58D fitting shell of latch component 56.All fingers are showd that in awaiting orders On position.As soon as moving into the associated driving sliding block of finger and corresponding plug and using position, which moves into latch position It sets.In order to which the finger to be locked on the latch position, locking guide groove 62 is provided on the downside of shell.The locking guide groove With groove.In the embodiment being shown here, the groove is separated with adjacent grooves by rod.Locking guide groove 62 shares four A groove: groove 64A, groove 64B, groove 64C and groove 64D.

Other various forms of locking guide grooves are also possible to useful；In general, the locking guide groove should have phase To the finger receiving element of shell firm position.As soon as finger 58 enters groove 64 associated with it, latch component 56 is in The state of an existing opposite shell firm position.The latch component just can not be moved with slide selector ontology 44 again as a result, It is dynamic；This uplink and downlink movement on view direction can be all blocked.

Figure 12 is the perspective view of other two component to cooperate of the change-over plug for travel.Two components also all show For under its " nature " position, that is, it is presented on the position in complete change-over plug for travel.Showing is lower housing section 14 And locking member 66.In a known manner, there are four sliding slots 42 parallel to each other for the lower housing section tool.Locking member 66 With known release button 40.Locking member 66 also has frame 68.On frame 68 equipped with can make locking member 66 with it is described The fixation clamp (it is not described in detail) that the other component of change-over plug for travel is connected.Locking member 66 is locked there are three also having Determine supporting leg: the first locking supporting leg 70A, the second locking supporting leg 70B and third 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 show together with the header body 32 for European plugs.Locking member 66 also with other header bodies and Haptic element cooperates, but is only retouched herein with function of the example of European plugs and corresponding plug ontology 32 to locking supporting leg It states.The header body is securely connect with the first driving sliding block 22, and the first driving sliding block 22 has guid arm 50.Header body 32 is also Connect slide protrusion 72.The slide protrusion can slide along the first locking supporting leg 70A and in the lower end of the first locking supporting leg 70A Lock state is presented.

Figure 14 shows the component in Figure 13, but is shown in a manner 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 slide on sliding surface 74.In order to start The sliding, locking member 66 can transverse shifting, can move and (scheme in the release direction that limits of direction by release button 40 In direction from right to left).To the flexibly prestress of locking member 66, so that slide protrusion 72 squeezes sliding surface 74.When slotting When head ontology 32 reaches it using on position, slide protrusion 72 reaches locking projections 76.Due to flexibly pre- to locking member 66 Add stress (so as in this figure, being therefore 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, this is because along the principal spread direction of supporting leg 70A is locked to this Locking supporting leg is loaded, and thus locking supporting leg 70A substantially need to only absorb compressing force.However, by pressing release button 40, This stop can be certainly discharged, also, the header body can be moved back on its standby position along sliding surface 74.

In a manner of more specifically being described in be broadly described and attached drawing, can production operation as snug as a bug in a rug and hardly The travelling converter for thering is operating mistake to occur.However, interestingly, the travelling converter and inexpensive is produced, and even if big Must be allowed in batch production it is larger it is fault-tolerant in the case where, can also inexpensively and reliably produce the travelling converter.
