Technical field

The utility model is related to a kind of change-over plug for travel, is also referred to as herein " travelling converter ".Use this turn Parallel operation, the attaching plug of a certain (country) standard can be inserted the power outlet of Reiseziel.Therefore, the travelling conversion Plug needs 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 The change-over plug for travel of the insertion at least power outlet of the first standard and the second standard.Additionally, in the change-over plug for travel One can be selected and use the first standard and the attaching plug of the second standard.

Background technology

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 the travelling conversion of the small-sized, power outlet for being suitable for some various criterions that is easy to carry about with one Plug.

The A of Chinese patent application CN 101872911 disclose a kind of change-over plug for travel with substantially round housing.Electricity Source plug is placed in the enclosure interior and can remove the housing.In this way, it is possible to use at least three kinds different types Attaching plug.Required attaching plug can be selected at relative lower housing section rotatable top shell part.The upper shell Part has a driving sliding block outwardly.The driving sliding block can be made to engage each attaching plug element.Therefore, by its Rotate to the position above the attaching plug, and when the position to the attaching plug is rotated, the power supply Plug will be removed from the housing.

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

The B4 of German patent DE 10 2,011 014 920 discloses another travelling converter, and it is referred to as " general conversion Plug ".Herein in travelling converter, multigroup pin is provided with 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 chute. The control element is guided using the baffle plate being arranged in external shell additionally.The baffle plate has guide rail, and institute Stating control element can be through groove thereon.The guide rail provides upper end position and lower end position.To the baffle plate flexibly 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 discharged from the end position, and move up or down, because except starting the control unit The selector (selector lever) for being also disposed at outside is also started outside part.Pressing the selector can move the baffle plate pair Anti- spring force.In this way, can from it or lower end position is shifted out by using control element pin.

In this scheme, outside control element is both used to be moved to pin group from first end position (standby position) The second end position (uses position), is additionally operable to lock those pin groups in these positions.Its drawback for existing is to make Selector also necessarily be in running status during moving pin group with control element.Comfortable singlehanded behaviour can not thus be carried out Make.The control element has also taken up the big quantity space of plug surface, thus can not freely be designed guidance type configuration, and And succinct structure type can not be obtained.

The content of the invention

The purpose of this utility model be to provide it is a kind of avoid it is of the prior art deficiency improved change-over plug for travel.Should Travelling converter cost-effective and should be able to be manufactured reliably, it is easy to transport and operation, and electricity aspect is very safe 's.

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

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

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

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

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

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

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

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

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

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

Therefore, under background of the present utility model, when the slide selector and the cunning can be moved between the chute At least one driving path between two adjacent sliding positions of dynamic selector be shorter than between two adjacent chutes apart from when, be have .It is typically useful when the slide selector can be just perpendicular or generally perpendicular mobile between the chute.When Whole between two adjacent sliding positions of the slide selector drive paths be all shorter than between two adjacent chutes apart from when, It is favourable.If the slide selector still can in vertical direction provide enough locking effects, then will be described It is useful that slide selector is arranged in an acute angle with perpendicular to the direction of the chute.Such case should be understood herein It is that " basic " is vertical.The sliding path of the slide selector that can be moved between the chute should not be limited by the chute System.

When plug has the engagement protrusion for being bonded on the catch elements, and the catch elements are engaged for each Projection 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.During do so, under background of the present utility model, the distance between two neighboring groove can be shorter than adjacent bond Distance between projection.

The catch elements can be designed to have the pectination cassette tape of the groove and card convex being arranged alternately.System can so be made The compact catch elements for making reliable operation are possibly realized.When the quantity one more than groove of the card convex that the cassette tape is included, Can also be useful.

In an especially succinct changeover plug, the cassette tape can be set to can be substantially perpendicular to the chute movement. During do 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.For the safe handling of change-over plug for travel For, even if when the plug counter pressure inserts power outlet, it is remained at using being critically important on position.At this In the system of utility model, settable stop or locking member are hindered with ensuring that the plug is maintained at using on position and by them Terminate in this.The locking member can prevent at least one plug of the change-over plug for travel；The locking member can also be effectively Multiple or all of plug is prevented using on position.

The locking member is designed to the part independently of the slide selector.Or, the locking member is also It can be a part being connected with the slide selector.As individual components implementation method its potentially have production on Advantage.The slide selector is need not to transmit or undergo part more energetically.However, due to the property of its own, the lock Determine element and must apply enough power to be maintained at using on position with by the plug of every kind of standard.

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

It is useful when the locking member Connection Release button, the release button is arranged at hull outside and along release Direction is driven.When by a plug by being moved back to standby position using position, such release button can make the locking member Discharge intuitively and safely.Such design compared with those by drive sliding block or slide selector, even plug itself some transport Move the design to discharge plug and seem safer, it is also more reliable.So that the release button will not be driven unintentionally, it also may be used It is with equipped with warning indicator or design warning coloration, such as red.The release button can be housing a part, for example, when by When the part for suitably designing the housing can be pressed.Generally, a recess is set on housing and is set in this recess The release button is put as the part independently of housing, is useful.Usefully, the release button can slide selection with described Device and/or the driving sliding block are positioned opposite.

Against the release direction, to the locking member (if there is provided if), flexibly prestress is (typically：Bullet Spring is biased) it is useful.To the locking member, flexibly prestress can make the plug once entering using position by can Lock-out state is snapped 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 that the locking member has at least one locking supporting leg, and The locking supporting leg has sliding surface and locking projections.The element being connected by mobile plug with one can be slided 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 it is such Slide protrusion is firmly connected, and the slide protrusion runs and can be in the locking projections (if setting on the sliding surface If having put) on lock-out state is presented.

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

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

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

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

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

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

With the first function element for being cooperated with first plug and for cooperated with second plug The latch component of two function element is useful.In order that the latch component is simple to manufacture and low cost, when first work( Energy element and the second function element are useful when constructing in the same manner.First function element and second Functional Unit Part all can be made from identical component or similar components.

It is special when the latch component has can be bonded on the finger in consolidating the receiver member being connected with housing It is not useful.Usefully, the function element includes finger form.The latch component can also have raised or projection, Rather than finger.The receiver member may be configured to, such as raised or sunken on breech lock guide member (latch guide). The receiver member can be also configured to groove or hole on the part that is connected on housing or with housing.

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

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

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

So as to engagement protrusion 52 can be made to be engaged 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.In the figure 7, again can be with It is seen in the lower housing section 14 and slide selector body 44 of its appropriate location in complete change-over plug for travel.Slide The back side of selector body 44 engages with the guid arm 50 of the described second driving sliding block.At its back side, the slide selector sheet Body has multiple card convexs, card convex 48A, 48B, 48C, 48D and 48E.Groove (groove 54A, 54B, 54C are provided between each card convex And 54D) form passage.Although in position shown in the figure, card convex 48C is engaged with the engagement protrusion of guid arm 50, When the slide selector body is in another location, the engagement protrusion of guid arm 50 is just no longer engaged with card convex.Conversely, moving Holding slide selector body 44 can make the card convex 48 of the guid arm be placed in groove top.Thus position, can be towards using position Put and move down the guid arm and and then entirely drive sliding block.

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

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

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

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

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

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

Figure 11 is the oblique view from slide selector body 44 and the lower section of latch component 56, 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 body 44.

Latch component 56 has four legs, its function element for forming the latch component, and end includes finger-like thereon Part 58A, 58B, 58C and 58D.The function element of these leg may pass through passage 54, and thus provide latch component 56 and slide Simple firm connection between selector body 44.In this view, it can be seen that latch component 56 in its lower end there is connection to block Son, more precisely with three connecting clamps 57A, 57B and 57C.These three connecting clamps can be placed in and be arranged at slip In through hole 59 on selector body 44.

It is provided with receiving the finger with respect to these three through holes 59 in the upper area of slide selector body 44 Recess 55.These recesses on slide selector body 44 can make latch component 56 simply be strongly attached to slide selector Body 44.Therefore, the latch component integrally can be fabricated by by metallic plate, be preferably fabricated by by flat spring.

Five card convexs 48 can also be one can easily see in this view forms pectination cassette tape 49.

Figure 12 shows identical part in top view.Finger 58 is can see from the top view to each other It is within close proximity, the passage is also within close proximity to each other.The length B for drawing describes the whole length that the passage is passed through.Cause This, length B is from the left end of first passage 54A to the right-hand member of passage 54D.The size comparison relevant with other parts 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 pointed to from lower housing section 14, it is possible to see female joint 18.Before latch component 56 is close to Shell wall；In feature change-over plug for travel, it is also kept by slide selector body 44, however, for visual simplification, Slide selector body 44 is not shown herein.

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

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

Figure 14 is the perspective view of part selected by multiple, therefrom it can be seen that the carrier supporting leg of each haptic element.Specifically, may be used To see that the support base 66A for American haptic element, support base 66A are connected to guid arm 50A.With support base 66A phases That adjacent is the support base 66B for Australia's formula haptic element, and it is connected to guid arm 50B.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, it is connected to guid arm 50D and is responsible for the movement European plugs.

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

Figure 15 is the top view of the part shown in Figure 14.Hereinafter, directional information is for example left and right, upper and lower refer to Description in Figure 15.It can again be seen that guid arm 50 and slide selector body 44 from the figure.It can also be seen that have card Convex 48A, 48B, 48C, 48D and 48E, these card convexs have been internally formed pectination cassette tape 49 in slide selector body 44.Each card Fluted 54 are set between convex 48, it can pass through the guid arm, can more precisely make the engagement unit 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 body 44, for European plugs guid arm 50D can make it is up and Downward movement.Can cause this motion using the first driving sliding block 22 (invisible in this figure) 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 body 44, card convex 48E does not engage guid arm 50D.

Guid arm 50 passes through section A, and the center of its 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), it is from the The left end of one passage 54A extends to the right-hand member of fourth lane 54D.Under background of the present utility model, across the passage length Section B it is 50% or the 80% of section A short than what the center of the driving sliding block passed through.

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

It is convex relative to the engagement of guid arm 50 according to the mathematical principle similar to cursor principle (Nonius principle) Block 52 sets the groove 54 of cassette tape 70.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 projections 52 is identical.However, two adjacent recessed Distance between groove 54 is shorter than the distance between two adjacent bond projections 52 or guid arm.In other words, between two adjacent card convexs 48 Distance guid arm 50 more adjacent than two or drive sliding block 22, the distance between 24,26,28 short.

Using this arrangement, when the slide selector body 44 is slided along the direction of arrow 68, first, 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 body 44 is reached after the position glissile segment B1 in Figure 15.

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

Correspondingly, when by 44 mobile section B3 of slide selector body, the right part of card convex 48A can be located at guid arm 50A Left side.Now can by guid arm 50A slide downwards pass through groove 54A, while other all of guid arm 50B, 50C and 50D is engaged by card convex 48C, 48D and 48E.Then, each in card convex 48 is at least partially disposed within the guiding being locked On the mobile route of arm 50.Therefore, in order to select another plug, most necessary is exactly that will slide to select by slide selector 20 Select the mobile section B3 of device body 44.Section B3 is more described second section long the 3 section.

The design of save space is possibly realized to a certain extent, because working as sunk projection (immersion It will not be completely Chong Die with the card convex when cams) being engaged with the card convex.Although verified only with enough overlaps Length, but even if partly overlapping for projection can also realize reliable locking state.

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

The design can be more convenient travelling converters operation, structure is more succinct, because slide selector 20 only needs to move The dynamic section than section A much shorters, corresponds to section B3 in the description of Figure 15.Under background of the present utility model, the slip The necessary displacement most long of selector be smaller than it is described driving its center across section A 30%, 50% or 80%.

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