Easy-operating change-over plug for travel

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 change-over plug for travel Need the socket of the first standard and the attaching plug of another standard.In this application, more precisely, being to be related to a kind of energy insertion At least change-over plug for travel of the power outlet of the first standard and the second standard.In addition, can be in the change-over plug for travel 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 travel plug.It is therefore desirable to small-sized, the power outlet for being suitable for several various criterions that is easy to carry about with one travelling conversion Plug.

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

The travelling converter has many purposes.But the relatively described lower housing section machinery rotatable top shell part needs Accurate shell production process is wanted, to allow the rotary motion of lower resistance and guarantee reliably to make the driving sliding block each A shell position engages attaching plug element.In addition, round itself is also a kind of limitation.In many cases, for example, it is block-like Perhaps, change-over plug for travel can be considered as more easily transporting.It, cannot be from a certain angle also, on round change-over plug for travel Degree sees all selectable attaching plug elements.

10 2,011 014 920 B4 of German patent DE discloses another travelling converter, is referred to as " general conversion Plug ".It is travelled in converter herein, multiple groups pin is provided in external shell.Every group of pin connects a control element, by Every group of pin can be mobile from outside described in those control elements.Guide the control element on the housing by sliding slot. Additionally the control element is guided using the baffle being arranged in external shell.The baffle has guide rail, and institute Stating control element can be across groove thereon.The guide rail provides upper end position and lower end position.Flexibly to the baffle Prestress, so that control element can be firmly held in the upper end position or lower end position.The control element and correspondence Pin group can be released from the end position, and move up or down, this is because first except the control is started The selector (selector lever) for being also disposed at outside is also started outside part.The baffle pair can be moved by pressing the selector Anti- spring force.It in this way, 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.The control element has also taken up the big quantity space of plug surface, thus cannot freely be designed guidance type configuration, and And succinct structure type cannot be obtained.

Summary of the invention

The object of the present invention is to provide one kind to avoid insufficient improved change-over plug for travel in the prior art.The travelling Converter 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 It moves and uses on position.Second plug is also connect with a driving sliding block, is used for the second plug is mobile from standby position To using on position.Therefore, the change-over plug for travel at least has the first driving sliding block and the second driving sliding block.Those drivings Sliding block can effectively be designed to button-like mode, mobile with a finger to make it easier to.It, can in order to accommodate the driving sliding block Sliding slot is set on shell.Those sliding slots can also be connected with each other to form the guide rail for the driving sliding block.In general, One sliding slot is set for each driving sliding block, and these sliding slots are arranged parallel to each other, is useful.

Slide selector is set on the change-over plug for travel, the slide selector can at least be moved to first position and On 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.For This, the slide selector has catch elements.

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.

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, being guided in sliding slot to it will usually become if loading onto spring to the driving sliding block It is less handy, this is because sliding block in this way tends to tilt, is run meeting " as hook ", just have bigger resistance certainly Power.

Therefore, in the context of the present invention, select when the slide selector and the sliding can be moved between the sliding slot Select at least one driving path between two adjacent sliding positions of device be shorter than between two adjacent sliding slots apart from when, be useful 's.It is usually useful when the slide selector can be just perpendicular or generally perpendicularly mobile between the sliding slot.Work as institute State whole driving paths between two adjacent sliding positions of slide selector be all shorter than between two adjacent sliding slots apart from when, be It is advantageous.If the slide selector still can provide enough locking effects in vertical direction, by the cunning Dynamic selector is arranged in an acute angle with the direction perpendicular to the sliding slot be useful.Such case should be construed as herein " basic " is vertical.The sliding path for the slide selector that can be moved between the sliding slot should not be by the limit of the sliding slot System.

When plug has engagement protrusion for being bonded on the catch elements, and the catch elements are directed to each engagement Convex block includes a groove, and the engagement protrusion may pass through the groove and be moved on a certain sliding position of the slide selector When, it is useful.When doing so, in the context of the present invention, the distance between two neighboring groove can be shorter than adjacent bond convex block Between distance.

The catch elements can be designed to have the pectination cassette tape of the groove and card convex that are arranged alternately.It can make to make in this way The compact catch elements for making reliable operation are possibly realized.When the quantity for the card convex that the cassette tape includes one more than groove, It is also possible to useful.

In an especially succinct changeover plug, the cassette tape can be set to can be substantially perpendicular to the sliding slot movement. When doing so, at least one engagement protrusion can be connected to corresponding plug by guid arm.

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.

The locking member is designed to the component independently of the slide selector.Alternatively, the locking member is also It can be a component being connected with the slide selector.As individual components embodiment its potentially have production on Advantage.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 lock Enough power must be applied being maintained at the plug of every kind of standard using on position by determining element.

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 Connection Release button be it is useful, which is set to hull outside and along release Direction is driven.When by a plug by using position to be moved back to standby position, such release button can make the locking member It discharges intuitively and safely.Such design is compared with those by driving sliding block or certain fortune of slide selector, even plug itself It moves to discharge the design of plug and seem safer, it is also more reliable.It, can also so that the release button will not be driven unintentionally Equipped with warning indicator or design warning coloration, such as red.The release button can be shell a part, for example, when by When a part for suitably designing the shell can be pressed.In general, a recess is arranged on shell and is set in this recess The release button is set as the part independently of shell, is useful.Usefully, the release button can be selected with the sliding Device and/or the driving sliding block are positioned opposite.

Against the release direction, to the locking member (if if being provided with), flexibly prestress is (typically: bullet Spring biasing) it is useful.To the locking member, flexibly prestress can make the plug once entering using position by can Lock state is caught in by ground.When the spring is accurately acted against the release direction, it is also advantageous in mechanical aspects.

One effective embodiment of (optional) locking member is the locking member at least one locking supporting leg, and The locking supporting leg has sliding surface and locking projections.It can be slided on the sliding surface with one by the element that mobile plug is connected. The element may be stuck at the locking projections later, 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 is run and can be in the locking projections (if setting on the sliding surface If having set) on lock state is presented.

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 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 at low cost, when first function Energy element and the second function element are useful when constructing in the same manner.First function element and second Functional Unit Part can all be made 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.Usefully, the function element includes 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 sunken on latch guide member (latch guide). 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.

Fig. 2 shows the change-over plug for travel from same visual angle.But in this change-over plug for travel, one of them Plug has been moved to using on position.Therefore, sliding select button 20 is located on the position of its sliding path left end.In this position Place, the driving sliding block on the left side are set, i.e., the first driving sliding block 22 is released, and driving sliding block 22 is moved to from upper position On lower position.European plugs 30 extend downwardly as a result,.The European plugs have header body 32 and the first haptic element 34A and the Two haptic element 34B.Meet in the power outlet of European standard in this way, change-over plug for travel 10 can be inserted into.Then travelling can be used to turn The female connector pair for inserting overhead allows not meeting the plug insertion of European standard.Specifically, these female connectors are to for UK English female connector to 18C and is used for the English grounding pin of UK to the American female connector of 18B, das US to 18A, AUS Australia formula female connector Connector 18D.

Fig. 3 shows same plug from another visual angle.The plug is in be moved with position identical in Fig. 2, i.e. European plugs To using on position.More haptic elements 36 (that is, haptic element of other standards) are also provided with it can be seen from housing bottom.This Outside, fuse insertion piece 38 is additionally provided on bottom.The insertion piece, to outer closure, a such as coin can be used to turn by visible lid The dynamic gap covered, to remove the lid and replace fuse.

In addition, release button 40 (invisible in view in front) is set in housing side.Release button accommodating In in shroud notch.More precisely, in recess is arranged in 14 the two of upper case portion 12 and lower housing section, and these are total With around release button 40.Pressing the release button can be such that the plug (European plugs 30 in such situation) pushed away down returns In shell.However, plug will not be pushed back in shell when not starting the release button, plug is inserted into power supply to work as Such case will not occur unintentionally when socket.

Fig. 4 shows the bottom of same change-over plug for travel, and other details can be more accurately seen from the figure, because This, will be described in detail these details in conjunction with this figure.The bottom view shows driving sliding block 22-28 and sliding select button 20 Without much stretching out lateral surface of shell.Succinct and convenient to use arrangement is allowed in engineering design of the invention, in this arrangement In, driving sliding block is within close proximity to each other.It slides select button 20 and is slightly higher than the driving sliding block, therefore stretch out ground and be slightly distal to They.

The haptic element of European plugs 34 is guided in header body 32, the haptic element of other standards plug is by from shell bottom Portion's export, and it is not provided with additional header body.Every two haptic element (i.e. a pair of of haptic element) is for being inserted into country variant standard In power outlet.Haptic element is used for Britain, the English haptic element of hereinafter also referred to as UK to 36A；Haptic element is used for Australia to 36B, under AUS Australia formula haptic element pair is also referred to as in text；Haptic element is used for the U.S., the American haptic element pair of hereinafter also referred to as US to 36C.It is additionally provided with and connects Ground terminal 36D, the ground terminal are used for Britain, therefore the English ground terminal of also referred to as UK, can be grounded using this connector.So And in general, such connector can also be provided when no ground terminal is available.It that case, this connector is for being inserted into UK The first pin (opening pin) of English power outlet, the first pin make it possible to be inserted into other two connector.

As can be seen that release button 40 is oppositely arranged with the driving sliding block and the sliding select button just.At this It is quite useful in a housing side by the sliding select button and all setting of driving sliding block under the background of invention 's.It for safety and intuitively operates, in general, release button 40 is arranged to corresponding thereto to be also useful.

Fig. 5 shows the component of the selected collaborative work of the change-over plug for travel in exemplary embodiment in perspective view, It illustrates lower housing sections 14.The header body 32 for belonging to European plugs is placed in below shell.The position of corresponding plug ontology 32 It sets, the first driving sliding block 22 is illustrated on lower position.On the front face, the shell has sliding slot 42.It can from figure To there are four the sliding slots 42 being disposed adjacent, wherein each sliding slot can receive a driving sliding block.However, rising for ease of understanding See, depicts only the first driving sliding block 22.It can be seen that slide selector ontology 44 is located at the top of the sliding slot, for accommodating The recess 46 and slide selector ontology 44 of the release button are opposite.

In addition, the slide selector ontology is illustrated in position when it is used in complete change-over plug for travel, but do not have Have and shows the component for maintaining it in this position.Description that this simplifies is also for being easy to understand.By slide selector ontology 44 are set to above the driving sliding block, i.e., relatively with housing bottom (haptic element can be exported by it and moved to using on position), It is useful.

Fig. 6 essentially shows the component shown in Fig. 5 from one side visual angle, depicts lower housing section 14 again And slide selector ontology 44.Slide selector ontology 44 is illustrated in its position kept by other component (not shown) again On.What is be also shown as is the second driving sliding block 24 of neighbouring first driving sliding block 22.First driving sliding block 22 is illustrated in lower portion And armed bit it sets, i.e., with the use position corresponding of plug, the second driving sliding block 24 is illustrated on upper position, i.e., Set corresponding position.

In this view, it can be seen that the back side (its inside towards change-over plug for travel) of slide selector ontology 44 has There is card convex 48.It can further be seen that the first driving sliding block is connected with guid arm 50.The guid arm 50 can be additionally by unshowned Component support, and ensure to drive the position of sliding block 22 and movement not only to be limited by sliding slot 42.However, in general, only in institute It has been enough for stating the guiding driving sliding block in sliding slot.The upper end of guid arm 50, which has, combines convex block 52.

So as to engage engagement protrusion 52 with card convex 48, so that the downward movement of the second driving sliding block 24 is suppressed.

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.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 is from the oblique view of 56 lower section of slide selector ontology 44 and latch component, card convex 48A, 48B, 48C and 48D It is high-visible in this view.It can be seen that groove 54A, 54B, 54C and 54D between the card convex.The groove not only may be used Pass through the engagement protrusion 52 of guid arm 50, but also latch component 56 can be made to be operatively connected to slide selector ontology 44.

Latch component 56 has four legs, forms the function element of the latch component, and end includes finger-like on it Part 58A, 58B, 58C and 58D.The function element of these leg may pass through channel 54, and thus provide latch component 56 and sliding Being simply bonded between selector ontology 44.In this view, it can be seen that latch component 56 has connection card in its lower end There are three connecting clamp 57A, 57B and 57C for son, more precisely tool.These three connecting clamps, which can be placed in, is set to sliding In through-hole 59 on selector ontology 44.

The finger can be received by being provided in the upper area of slide selector ontology 44 with respect to these three through-holes 59 Recess 55.These recesses on slide selector ontology 44 can make latch component 56 simply be strongly attached to slide selector Ontology 44.Therefore, the latch component can be integrally fabricated by metal plate, be preferably fabricated by flat spring.

It can also be one can easily see five card convexs 48 in this view and form pectination cassette tape 49.

Figure 12 shows identical component in top view.It can see finger 58 to each other from the top view It is within close proximity, the channel is also within close proximity to each other.The length B drawn describes the whole length that the channel passes through.Cause This, length B is the right end from the left end of first passage 54A to channel 54D.Size comparison related with other components sees following Diagram in.

Figure 13 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 (bars).Lock guide groove 62 There are four grooves altogether: 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 14 is the perspective view of multiple selected components, therefrom it can be seen that the carrier supporting leg of each haptic element.Specifically, can To see that the support base 66A for American haptic element, support base 66A are connected to guid arm 50A.With support base 66A phase Adjacent is to be connected to guid arm 50B for the support base 66B of Australia's formula haptic element.It can be seen that adjacent with support base 66B For the support base 66C of English haptic element, it is connected to guid arm 50C.It can be seen that the support bottom adjacent with support base 66C Seat 66D is connected to guid arm 50D and is responsible for the mobile European plugs.

As can be seen, the release of guid arm 50 depends on the position of slide selector ontology 44, and sliding choosing can be used Select the position that button 20 adjusts slide selector ontology 44 from the outside.

Figure 15 is the top view of the component shown in Figure 14.Hereinafter, directional information is for example left and right, upper and lower refers to Description in Figure 15.It can again be seen that guid arm 50 and slide selector ontology 44 from the figure.It can also be seen that have card Convex 48A, 48B, 48C, 48D and 48E, these card convexs form pectination cassette tape 49 inside slide selector ontology 44.Each card Fluted 54 are arranged between convex 48, the guid arm can be made to pass through, can more precisely make the engagement member of the guid arm Part (invisible in this figure) passes through.Corresponding groove is described groove 54A, 54B, 54C and 54D.

On the position of shown slide selector ontology 44, the guid arm 50D for European plugs can make uplink and Downward movement.It can cause this movement using the first driving sliding block 22 (in this figure invisible) for being connected to guid arm 50D.Other Guid arm 50A, 50B, 50C are engaged by its respective engagement protrusion with the pectination cassette tape 49.

Guid arm 50A is prevented by card convex 48A, and guid arm 50B is prevented by card convex 48B, and guid arm 50C is prevented by card convex 48C. On the position of shown slide selector ontology 44, card convex 48E does not engage guid arm 50D.

Guid arm 50 passes through section A, and the center of self-aiming arm 50A extends to the center of guid arm 50D.Section A is also corresponded to The length that the center of the driving sliding block passes through.It can be seen that groove 54 passes through shorter section, section B (referring to Figure 12), from the The left end of one channel 54A extends to the right end of fourth lane 54D.In the context of the present invention, across the section B of the passage length 50% or the 80% of the section A that the center of the comparable driving sliding block passes through wants short.

In order to select another plug, firstly, European plugs 30 are slided to lower housing section 14 using driving sliding block 22.In It is that the groove 54D that the engagement protrusion 52 of guid arm 50D will pass through cassette tape 49 is moved up.Then, by sliding select button 20 select another plug by sliding the slide selector ontology 44 along the direction of arrow 68.Then, card convex 48E is fixed The guid arm 50D of sliding block 22 is driven, and according to slide selector ontology 44 or the release of the position of the cassette tape 70 with groove 54 is another The guid arm 50 of one plug.

It is convex relative to the engagement of guid arm 50 according to the mathematical principle similar to cursor principle (Nonius principle) The groove 54 of the setting cassette tape 70 of block 52.For whole grooves 54, the distance between two adjacent grooves 54 is identical.Equally Ground, for whole engagement protrusions 52, the distance between two adjacent bond convex blocks 52 is identical.However, two adjacent recessed Distance between slot 54 is shorter than the distance between two adjacent bond convex blocks 52 or guid arm.In other words, between two adjacent card convexs 48 Distance than two adjacent guid arms 50 or driving sliding block 22,24,26,28 between distance it is short.

Using this arrangement, when sliding the slide selector ontology 44 along the direction of arrow 68, firstly, just When the left side that the right part of card convex 48C is slided into guid arm 50C or the left side of engagement protrusion 52 for sliding into guid arm 50C, just Guid arm 50C can be discharged.Then, guid arm 50C and engagement protrusion 52 can be moved downwardly through groove 54C.Slide selector This position of ontology 44 is reached after the position glissile segment B1 in Figure 15.

If further sliding the slide selector ontology 44 along the direction of arrow 68 now, guid arm 50C is just It can be engaged by card convex 48D.The plug of guid arm 50C cannot remove outside shell again.Equally, guid arm 50D is still by card convex 48E Engagement fixed.One is removed to the right part of card convex 48B in the left side of guid arm 50B, will discharge guid arm 50B and be somebody's turn to do Guid arm and engagement protrusion 52 together can slide downward pass through groove 54B.This position is the slide selector ontology 44 from Figure 15 Position set out and reach after the displacement of section B2, section B2 is the second segment compared with first segment B1 long.

Correspondingly, when by 44 mobile section B3 of slide selector ontology, the right part of card convex 48A can be located at guid arm 50A Left side.Now can by guid arm 50A slide downward pass through groove 54A, while other all guid arm 50B, 50C and 50D is engaged by card convex 48C, 48D and 48E.Then, each of card convex 48 is all at least partially disposed within the guiding being locked In the movement routine of arm 50.Therefore, in order to select another plug, most necessary is exactly to select sliding by slide selector 20 Select 44 mobile section B3 of device ontology.Section B3 is more described second section long third section.

The design of section space-efficient is possibly realized to a certain extent, this is because working as sunk convex block (immersion It will not be completely Chong Die with the card convex when cams) engaging with the card convex.Although verified only with enough overlappings Length, but reliable locking state may be implemented partly overlapping even if convex block.

In this way, compared with the legacy card band only with a groove, slide selector 20 can be obtained obviously more Short driving path.If only having a groove, in order to select to have the plug of guid arm 50A, slide selector 20 is necessary By from for showing that a section A is removed in position shown in the Figure 15 of selection with the plug of guid arm 50D.This section of A is equal to first and drives The distance between guid arm 50D and the guid arm 50A of 4 wheel driven movable slider of movable slider 22, and obviously than above-mentioned section B3 long. For other guid arms 50C and 50B, section B1 and B2 as driving path are also than with only with the card of a groove Wanting for item is short.

The design can be such that travelling converters operation is more convenient, structure is more succinct, this is because slide selector 20 only needs to move The dynamic section than section A much shorter, corresponds to section B3 in the description of Figure 15.In the context of the present invention, the sliding selection Device longest necessity displacement be smaller than it is described driving center across section A 30%, 50% or 80%.

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.
