Can safe transport change-over plug for travel

Technical field

The present invention relates to a kind of change-over plug for travel (travel plug adapter), " trip is also referred to as herein Row converter (travel adapter) ".Using this converter, the attaching plug of a certain (country) standard can be inserted into trip In the power outlet of row destination.For this reason, the change-over plug for travel needs the socket of the first standard and the power supply of another standard Plug.In this application, more precisely, being to be related to a kind of power outlet that can be inserted at least the first standard and the second standard Change-over plug for travel.For this reason, a power supply using the first standard and the second standard can be selected in the change-over plug for travel Plug.

Background technology

When global tourism and trade increasingly increase, such travelling conversion plug is just more and more being used Head or travelling converter.It is therefore desirable to it is succinct, be easy to the trip of the power outlet for being suitable for some various criterions that transports Row changeover plug.

101872911 A of Chinese patent application CN disclose a kind of travelling converter with substantially round housing.Electricity Source plug, which is placed in the enclosure interior, can simultaneously remove the housing.In this way, at least three kinds of different types can be used Attaching plug.Required attaching plug can be selected at opposite lower housing section rotatable top shell part.The upper shell Part has an outstanding driving sliding block.The driving sliding block can be made to engage each attaching plug element.For this reason, will The sliding block, which is rotated to the position above the attaching plug, the attaching plug, to be removed from lower section from the housing.

The change-over plug for travel has many purposes.But people are still intended to provide a kind of upper easier travelling of operation Converter.Especially, if distributing different plugs different control elements and by being carried out to allocated control element The plug can be transferred to using seemingly favourable on position by operation.Also, the plug is back to and can clearly be recognized And firm standby position should also be what is be easily achieved.

10 2,011 014 920 B4 of German patent DE discloses another travelling converter, it is referred to as " general turn Insert head ".Travel at this in converter, 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.For this by sliding slot on the housing to the control Element processed is guided.Additionally the control element is guided using the baffle being arranged in external shell.The baffle With guide rail, and the control element can be to pass through groove thereon.The guide rail provides upper end position and lower end position. To the baffle flexibly prestress, so that control element can be firmly held in the upper end position or lower end position.Institute Stating control element and corresponding group pin can discharge from the end position, and move up or down, herein except startup The selector for being also disposed at outside is also started outside the control element.Pressing the selection bar can move the baffle confrontation bullet Spring force.In this way, can from it or lower end position is shifted out by using control element pin.

In this scheme, exterior control element was both used for those group of pin from first end position (standby position) The second end position (using position) is moved to, is additionally operable to those group of pin locking over these locations.Its existing one Drawback is that selector also necessarily be in operating status during pin group is moved using control element.It cannot thus relax Suitable one-handed performance.The control element has also taken up the big quantity space of plug surface, thus cannot freely be designed Guidance type configures, and cannot obtain succinct structure type.

The content of the invention

Insufficient improved change-over plug for travel of the prior art is avoided the object of the present invention is to provide a kind of.The trip Row converter should be able to be economical and be reliably manufactured, and is easy to transport and operates, and electricity aspect is very safe.

The change-over plug for travel of the present invention has housing, which can have variously-shaped.It is for example, in general, block to fortune It is very practical for defeated.But be designed to can be largely for the structure (mechanics) of change-over plug for travel of the present invention The shape of upper unrestricted choice housing.Favourable when housing has at least one plane, but invent structure be also suitable for it is curved Bent surface of shell.The housing may be designed to one or more.Have confirmed, it is useful that the housing is configured to two parts , specifically lower housing section and upper case portion.It is removably connected to each other, such as uses machinery Means, are useful using screw connection.

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, If to assign Schuko plugs on the socket, just there is substantially cylindrical sunk part on the socket, additionally have It is useful for assigning the female connector (female connector) of the haptic element (contact pins) of the Schuko plugs.For it The plug of his type, it is not necessary to which there is depression or groove.It is useful to set flat upper casing dignity, can be set on the face more A female connector (female contact).In general, at least two female connectors should be set, it, which is formed, is used to assign standard plug Female connector pair.In order to assign the plug of multiple and different standards, multiple female connectors are set to being useful.If plug is also With earth conductor, and socket meaning will provide the chance of ground connection, in general, setting the 3rd mother to each plug to be assigned Connector or the 3rd connector (contact) are also necessary.

The change-over plug for travel should also have the plug of at least one 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 To be, such as EU European plugs, the plug of the second standard can be the American plugs of US.These plugs can have two pins, That is, they are earth-free；Alternatively, they can have three pins, to provide grounding pin.Therefore, travelling conversion plug of the invention Head is suitable for using in more than one country.Usefully, and usually, select one is using first plug and the second plug It is necessary.

The change-over plug for travel may also include three or more plugs.Have confirmed, with three or four plugs Change-over plug for travel be highly useful.At least one of which plug (but typically all plugs) can be by from armed bit (in this position, plug is placed in housing substantially) is put to be moved to using on position.Using position, ground can be used completely in plug Or it is at least partially disposed in outside housing.Regularly, when plug is back to standby position, plug can be moved back in housing completely.Insert It is useful that head, which can be moved back in housing enough as far as it without prejudice to other plugs,.

First plug is connected with a driving element, which is used for first plug from standby position Move to and use position.Second plug is also connected with a driving element, it is used to move to the second plug from standby position and makes Use position.Therefore, the change-over plug for travel at least has the first driving element and the second driving element.Those driving elements Button-like mode can be effectively designed to, to make it easier to be moved with a finger., can be in order to house the driving element Sliding slot is set on housing.Those sliding slots can also be connected with each other to form the guide rail for the driving element.In general, One sliding slot is set for each driving element, and these sliding slots are arranged parallel to each other, is useful.

Slide selector can be set on the change-over plug for travel, which can at least be moved to first Put and the second place.The slide selector alternatively discharges first plug in its first position, is discharged in its second place Second plug, thus, it is possible to move to the plug using on position.For this purpose, the slide selector has locking member Part (blocking element), such as convex block (cam) can be used to be used as catch elements, the convex block and moving guide rail (displacement track) is engaged.But within the scope of the invention, it is not necessary that slide selector as setting. The slide selector is optional, can select to use the slide selector in addition to means described below.

Since change-over plug for travel should be always configured to succinctly, the driving element usually each other from very Closely.The driving element is usually designed to sliding block, therefore, hereinafter puts up with driving sliding block and its function and advantage are described. So be not precisely placed on driving sliding block will inadvertently while mobile neighbouring driving cunning for such as finger The situation of block will be easy to occur.However, since the present invention only allows to drive a plug, thus (usual) also only allows One driving sliding block of driving, so the driving sliding block that touches of imprudence will not move, (or it will not at least move related insert Head).This can make the operation of the change-over plug for travel become more fault-tolerant.

As mentioned, it is useful when having sliding slot or similar groove on the housing of the change-over plug for travel.Institute Stating driving sliding block can run in these sliding slots.Can also be that the slide selector sets a sliding slot.These sliding slots can make cunning Block is moved while being directed to.Therefore, it embodies a kind of favourable and efficient mechanical conceptual of cost.Due to usual Multiple driving sliding blocks are set on change-over plug for travel, so work as to guide in the sliding slot in a simple manner During multiple driving sliding blocks, it is particularly advantageous.In the context of the present invention, the driving sliding block must only cause the plug Movement, movement typically up and down.(compared with other common converters) described driving sliding block need not be by described in Plug is locked in using on position, need not also ensuring a plug whenever only may be selected.Because the drive under background of the present invention Movable slider, which is only allowed, performs a kind of function, it is possible to easily and reliably it is guided in sliding slot.For example, such as Fruit to it is described driving sliding block load onto spring, then carrying out guiding to it in sliding slot will become poorly to use, this be typically by Tend to tilt in such sliding block, run meeting " as hook (hook-like) ", just have the resistance of bigger certainly.

According to the present invention, first plug is allocated a stopping element (arresting element).Stopped by this Dynamic element, the plug can be stopped on standby position.Due to this interception, the free mobility of the plug by This is reduced, i.e. the resistivity for using being moved to position in standby position is more than on the centre position of the driving element (standby position and use the position between position).

An open position and a closing position can be presented in the stopping element, wherein, pass through the movement of first plug The stopping element can be transferred in the closing position by the open position.

The stopping element can be transferred to by the closure position by the open position by the movement of first plug Put.Here, being typically to move up first plug, that is, move to its standby position.For the stopping element to be moved Extra driving to the screw (bolt) or element of the closing position is unnecessary.Following setting can also be done, passes through institute The movement for stating the first plug can also be moved on to the stopping element on the open position by the closing position.For inciting somebody to action The extra driving that the stopping element moves to the screw or element of the open position is also unnecessary.Thus, it is described Element is suitable for its function as a stopping element, and still, this transfer must be implemented at least for a resistance, and And in some cases, this transfer can also be prevented from, for example, when another plug is in using on position.It is this Prevention can be by a slide selector or otherwise (such as passing through a locking mechanism) provides.

Under any circumstance, the stopping element, which may ensure that, prevents the plug on the standby position.When When the change-over plug for travel only has first plug, a kind of mechanism not cooperated with other plugs is set.Citing For, a single unlocking lever (unlocking lever) can be set.In some implementation profits, use can also be set In be resiliently biased the stopping element enter the closing position element.

Under any circumstance, the stopping element may ensure that the standby position of clear definition.There is no such stop In the known travelling converter of element, the driving element (can usually be started for example, sliding along the direction using position Device) movement is a bit of, and when there is provided preventing that two plugs from moving on to using mechanism on position at the same time, such case is usual It can also occur.Therefore, these plugs just have the defects of standby position is not presented in a well defined manner.For example, user can lead to Two plugs are stuck in on using the midway of position by driving while crossing two driving elements.In addition, for conversion plug of travelling Such a is the situation of an allergen for its conductive security, even driving element from standby position only Part mobile (and the plug is not moved on to fully using on position) is possible, is also not for a user Allow what people trusted.The stopping element thus provides the standby position of clear definition.Herein, the stopping element closes Position correspondence is closed in the standby position of plug.When plug moves on to it using on position, in contrast, the stopping element is then It is transferred to its open position.

When the stopping element be configured to one be kept completely separate with the driving element component when be favourable.It is described to stop Dynamic element for example can be configured to a movable rod (movable lever).Here, wise is structured to a tiltable bar (tiltable lever), particularly around the inclined bar of single rotation axis (lever), the rotation axis is preferably laterally in described The rotation axis of the direction of motion of driving element.Can be to the direction of the bar closing position to the bar flexibly prestress；Also This can be alternatively or additionally supplied to another close mechanism.

Such change-over plug for travel is favourable：Each of which plug is all allocated support component and the stopping element Act on the support component, i.e. optionally it prevent and thus prevent the plug on standby position.Institute State support component and for example may be configured to support arm, its one side carries the haptic element of the plug, on the other hand establishes and the drive The connection of dynamic element.Particularly when the support component with depression (depression) and the stopping element have it is raised, And the stopping element the protrusion it is engageable in the depression the plug is maintained at stop position (arrested Position it is favourable on).Such protrusion can be formed at the rod end in a manner of extremely simple and is favourable.

Such change-over plug for travel is useful：It is additionally provided with the second plug of the second standard, it is same allocated One driving element, which is designed to mobile second plug between standby position and using position, in armed bit Put, second plug is placed in the housing substantially, in using position, second plug can land used be placed in the housing Outside.Here, second plug is allocated the second stopping element, second plug can be hindered by second stopping element Only in the standby position, and an open position and closing position can be presented.

For such change-over plug for travel, the mobile route of first driving element and the second driving element Define a plane of motion.The stopping element is advantageously placed in this planar back side.So permissible travelling converter is extremely Succinct design and the structure for structure (mechanics) the interference stopping element for preventing the driving element.In addition, work as The structure of the stopping element pass through for the put-through channel (be usually the sliding slot) of the driving element it is invisible when, recognize It is aesthetic more to meet.

It is favourable when pivoting point of the stopping element behind the shifting axle rotates.For example, can be at that In rotation axis is set to rotate the toggle link (toggle lever).The position of the plane of motion " below " is understood as It is directed toward the position in enclosure interior direction.In addition, when the stopping element is arranged at the driving element top and thus basic bit It is favourable when above the sliding slot (or correspondingly described shell nozzle).

In the case of change-over plug for travel with two plugs, when the movement by first plug can be by institute It is favourable to state when the stopping element of the second plug is transferred in closing position by open position.This transfer may also include only It is fixed in closing position.Then the stopping element is not only with the security-related standby position for accurately defining plug Function, but also have the function of to ensure that second plug is influenced by the position of first plug.Therefore, the stop Element can have the function of to be, for example, that the rotation for selecting plug casing described in a plug has, or have the slide selector The function that can have in this context.

It is favourable, institute when at least one stopping element (or possible whole stopping elements) is connected with control-rod Stating control-rod allows or prevents at least one stopping element (or possible whole stopping elements) from moving on on open position.Institute State control-rod or refer to and may be configured to a single element, and can be connected with the stopping element or can be with the stopping element one It is body formed.For example, it has already been proven that U-shaped bar (lever) is useful, one rod end has an element or particularly one Protrusion, can coordinate with the support component of plug or particularly plug.The other end of the U-shaped bar can then be used as control-rod Or refer to.

It is favourable when the control-rod is bonded in a blocking unit, the blocking unit will be described at least one Stopping element is fixed in closing position.Advantageously, the blocking element can have at least one blocking sliding block, it can be with base This is moved parallel to the rotation axis of at least one stopping element.When at least one blocking sliding block (preferably whole blockings Sliding block) it is favourable when being arranged on a moving guide rail.When towards one end of the moving guide rail at least one blocking Sliding block flexibly prestress when be also advantageous.All these measures on the blocking unit result in each plug Between effective cooperation.Here, the positional information (using position or locking position) passes through the stopping element and control-rod Position and then (forwarded) is passed to control-rod by the position of the blocking sliding block, and then is transferred to stopping element.

It is extremely to have above the sliding slot to set at least one blocking sliding block (or possible whole blocking sliding blocks) Profit.At least one blocking sliding block (or possible whole blocking sliding blocks) is set to be also advantageous behind the sliding slot. The operating principle of favourable simple design and the optimization with attractive appearance can so be produced --- such as above for described Mentioned by the position of stopping element.

It is also to have when the second blocking sliding block of the first blocking sliding block and the second length that set at least one first length Profit.Here, second length can be equal to first length, still, second length can also be more than described first Length.The distance that the second larger length allows between each plug differs, or even can pass through the suitable of the blocking sliding block Closing length makes the distance between each plug relatively free to select, and still provides the reliability service of the blocking unit.

The plug can be moved to the help of the driving element using on position.For change-over plug for travel For safe handling, even if when the plug counter pressure is inserted into power outlet, it is remained at using being favourable on position 's.In the system of the present invention, stop or locking member (arresting or locking element) can be set to ensure The plug is maintained to be prevented in this using on position and by them.The locking member can prevent the change-over plug for travel At least one plug；The locking member effectively can also prevent multiple or all plugs using on position.

It is useful when the locking member connects a release button, which is arranged at hull outside and edge Release direction is driven.When by a plug by being moved back to standby position using position, such release button can make the locking Element is directly perceived and safely discharges.Such design is compared with those by driving sliding block or slide selector, even plug itself Design of some movements to discharge plug seems safer, also more reliable.So that the release button will not be driven unintentionally Dynamic, it can also be equipped with warning indicator or design warning coloration, such as red.The release button can be a part for housing, For example, when due to suitably design a part for the housing can be pressed (depressed) when.In general, set on housing The one recess and release button is set in this recess is useful as the part independently of housing.Usefully, it is described to release Putting button can be positioned opposite with the slide selector and/or the driving sliding block.

Against the release direction, to the locking member (if if being provided with), flexibly prestress is useful. To the locking member, flexibly prestress can make the plug be reliably caught in locking shape using position once entrance State.When spring is accurately acted against the release direction, it is also advantageous in mechanical aspects.

One effective embodiment of (optional) locking member is that the locking member has at least one locking supporting leg, and The locking supporting leg has sliding surface and locking projections.It can be slided with one by the element that mobile plug is connected on the sliding surface. The element may be stuck at the locking projections afterwards, 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 so Slide protrusion firmly connect, and the slide protrusion is run and can be in the locking projections on the sliding surface Lock-out state is presented, if if being provided with.

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 few It is also useful and enough when the quantity of plug.

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 all when being run on the same locking supporting leg of the locking member.Due to the two slide protrusions Run on same locking supporting leg, therefore, this means that the two slide protrusions in same sliding surface and same lock tab Rise and run on (lock-out state can be presented on it for two slide protrusions).Because two on the change-over plug for travel are inserted Head, which will not be simultaneously displaced, to be used on position, so this alternatively can be presented in the locking projections in the slide protrusion Lock-out state.However, if two slide protrusions, such as two slide protrusions of adjacent header, a shared size are suitable If locking supporting leg, then the quantity of locking supporting leg can be reduced, thus the change-over plug for travel can be configured to more succinct.

Other features and advantage of the present invention can be obtained from following attached drawing and its associated description.With reference to diagram and its The feature of the present invention is described in associated description.However, these features can also be included in other combinations of present subject matter In.Therefore, disclosed each feature combines it will be also be appreciated that being disclosed in rational on other feature technologies.Part illustrates Slightly it is simplified, and is schematical.

Therefore, it is that the formula plug selection of AU Australia exists compared with the grounding pin in the plug casing 40 of Schuko plugs The outer set-up mode guided to conductive haptic element of the plug casing of Schuko plugs.In contrast, the conduction of the American plugs of US Haptic element is directed in the header body 40 of Schuko plugs.Both schemes all allow favourable and space-saving set Put mode.Different schemes may be selected for different plugs.

Fig. 7 is the stereogram of the component of the selected collaborative work of travel plug 10.First support 60 is shown in figure, its Supported as guide element and guide each haptic element (not particularly pointing out).Second support is also shown, it similarly guides multiple Haptic element.The 3rd stent 64 is also shown in figure.Stent 60 and 62 is illustrated in upper position, the i.e. position corresponding to its standby position Put.3rd stent 64 is illustrated in the position moved down, it, which corresponds to, uses position.Stent 60 is connected with driving element 66.Its Remaining stent is similarly connected to driving element, but it is invisible from this visual angle.In addition, the stent also with head part (head Pieces) it is connected, specifically, 60 connector component 68A of stent, 62 connector component 68B of stent, and stent 64 connect head Part 68C.

It is also provided with three restraint sliding blocks (blocking slides), i.e. restraint sliding block 70A, 70B and 70C.These limits Movable slider is run on moving track 72.This moving track 72 extends between first end 72 and the second end 76.At the both ends Boundary element is set, and which defines the boundary that the restraint sliding block is run at 72 both ends of moving track.In first end component 74 can also set a helical spring (not shown), it applies restraint sliding block 70C pressure with towards the of moving track 72 Two end pieces 76 are to its prestress.This pressure is transferred to restraint sliding block 70B and 70A by restraint sliding block 70C, so that towards The second end component 76 of moving track 72 is to whole restraint sliding block flexibly prestress.

The length available (length i.e. between first end component 74 and the second end component 76) of moving track 72 is slightly longer than The sum of length of restraint sliding block 70A, 70B and 70C.Therefore, gap 78 can be formed between restraint sliding block 70.The head of one stent It is engageable in this gap.In the plug position of Fig. 7, head 68C is bonded on the sky between restraint sliding block 70B and restraint sliding block 70C In gap 78.Head 68C can be moved by the gap, so that it reaches the lower position of diagram, it, which corresponds to, distributes to stent 64 plug uses position.However, in this position, head part 68C is filled with shifting with restraint sliding block 70A, 70B together with 70C Length available on dynamic rail road 72.So as to which there is no gap or any gap to allow head 68A and 68B to be connect with restraint sliding block Close --- in other words, there is no any space for Second gap for allowing another head to pass through.

In this way, locking mechanism 58 is thereby establish, which ensure that whenever only having a plug to move to it makes With on position.Inclined-plane 80 can be set at the edge of the restraint sliding block, so head part 68 can be made easily to pass through.Correspondingly, Head part 68 can have the cone point (tapered point) in 82 form of cutting tip of its lower edge.So also contribute to head Component 68 is inserted into the gap between restraint sliding block 80.However, the length available of moving track 72 all should be in size under any circumstance On make (no matter such insertion and pass through auxiliary member) and be not more than a head component 68 and be movable to using position.Generally, Thus mechanism that is simple and accurately running can be established, it additionally to set slide selector to seem unnecessary.The mechanism also assures Obvious standby position is presented or using position in each driving element.What user is never currently at suspection plug Kind state.In contrast, change-over plug for travel of the prior art allows plug along standby position local motion sometimes, for example, When stopper (blocker) only postpones to be bonded on sliding slot.

Fig. 7 shows the stereogram of selected component, can be determined based on this favourable in the scope of the invention in embodiment Locking mechanism.Three driving elements drive sliding block 84, second for UK British connecting plugs for the first of the American plugs of US Sliding block 86 and the form for the 3rd driving sliding block 88 of AU Australia formula plug is driven to show.Certainly, the locking mechanism 90 shown It can also cooperate with other plugs, such as the set-up mode shown in Fig. 1.Locking mechanism 90 transfers to include 92 conduct of moving track One element.This moving track 92 extends between first end component 94 and the second end component 96.Helical spring 98 is resisted against End member 94 and suitable for towards moving track 92 the second end component 96 with elastic type to each restraint sliding block pre-add Stress.

Helical spring 98 is arranged at the first restraint sliding block 100A, it also acts on and (transmitted by the sliding block) the second restraint Sliding block 100B and the 3rd adjacent restraint sliding block 100C.Each restraint sliding block is both provided with guide check (guide cheeks), i.e., Guide check 102A, 102B and 102C.Inclined-plane (bevels), i.e. inclined-plane 104A, 104B are also set up in the end of the restraint sliding block And 104C.

Rocking bar (rocker levers) is arranged at the top of moving guide rail 92.Distribute to each driving element and (thus) inserts The rocking bar of head their own.Rocking bar 106A distributes to driving element 84, and rocking bar 106B distributes to driving element 86,106C points of rocking bar Dispensing driving element 88.(not shown) rotation of rotation axis of the rocking bar around the lower section of moving track 92.Rotation axis is generally flat Row is run in moving track 92.Each rocking bar has refers to (control finger) 108 with its integrally formed control.To be clear Chu Qijian, this has carried out detailed sign just for rocking bar 106C.Card convex 110 refers to 108 with control and is oppositely arranged.This card convex can be with Associated driving element engages and can be fixed in standby position.Below in conjunction with next width diagram to having herein Effect mechanism is described in detail.

What it is from this it can be seen from the figure that is that rocking bar 106C is located at lower position.In this position, control refers to 108 positioned at movement The surface of track 92.In this position, only when having suitable gap between restraint sliding block 100C and the second end component 96 Shi Suoshu controls refer to and could pass through.Control refers to 108 engagements in this gap.Guide check 102C and inclined-plane 104C ensure that with Rocking bar 106C is moved, and control, which refers to 108, can positively stretch into this gap.The gap is dimensionally made once the control refers to and stretches Enter in the gap, then restraint sliding block 100A, 100B and 100C cannot be moved again.It is also one that control to other rocking bars, which refers to, Sample.

When rocking bar 106C is transferred to its upper part position, it corresponds to the standby position of driving sliding block 88, is controlled in this position System refers to 108 above restraint sliding block 100C, has space to move all three restraint sliding blocks.Correspondingly, driving is distributed to slide The rocking bar 106B of block 86 then can be transferred to lower position.Here, its control-rod guided by guide check 102B and inclined-plane 104B will Restraint sliding block 110C is slided to the right towards the second end component 96.However, this is probably because due to the correspondence position of rocking bar 106C Putting makes there have available gap.

Fig. 8 shows the selected component shown in Fig. 7 from different visual angles, again illustrates driving sliding block 84,86 and 88. Driving sliding block 84 and 86 is in standby position with corresponding plug.Driving sliding block 88 is in corresponding plug and uses position.Figure In merely illustrate to describe rocking bar the necessary component of operating principle.For rocking bar 106C, it can be seen that card convex 110C can be with Drive corresponding holding section 112C engagements on sliding block 88.Such holding section can frequently convenient be designed to a groove.The drive Anti- convex (counter cam) 114C is additionally provided with movable slider.When the driving sliding block is moved on to corresponding to its standby position Upper position when, anti-convex 114C can press to the pressure face 116C on rocking bar 106C.So rocking bar 106C can be made to move back to thereon Portion position.Here, card convex 110C is engaged with holding section 112C.Thus the connection of form fit formula is set up, driving sliding block 88 is protected Hold in upper position.The rocking bar can firmly hold institute's rheme with loading spring with the position independently of restraint sliding block Put.However, once restraint sliding block 100C is moved, and the position of rocking bar 106C refers to 108 by control and fixes, and drives sliding block 88 Firmly and its upper part position will be securely maintained at.

It will be clear that the fixation of the upper position of driving sliding block 86 from figure.In this position, card convex 110B is with driving The holding section 112B of movable slider 86 is fixedly connected.In addition, anti-convex 114B is engaged with the rocking bar.Restraint sliding block 100C is prevented Control-rod 108B and rocking bar 106B is moved down as an entirety.

It is also apparent that the fixation in the region of card convex 110C can firmly fix the plug from this view Whole elements.Only when the rocking bar discharges holding section 112, the supporting rod 118 for AU Australia formula plug just can be downward It is mobile.This supporting rod again reliably guides downwards and upwards conductive haptic element 120A, 120B and ground connection haptic element 122.

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 Have the travelling converter of operating mistake generation.However, it is attractive that, the travelling converter and inexpensive is produced, and i.e. Make to must be allowed in mass production it is larger it is fault-tolerant in the case of, can also inexpensively and reliably produce the travelling converter.
