Definitions

  • the present invention relates to a travel plug adapter, which is also referred to herein as a travel plug for short.
  • a travel plug adapter With the help of such an adapter, power plugs of a specific (domestic) standard can be plugged into the sockets available at the travel location.
  • the travel plug adapter requires a plug socket of the first standard and a mains plug of another standard.
  • the present case is more specifically about travel plug adapters, which enable plugging into sockets of at least a first and a second standard.
  • mains plugs of a first and a second standard can be used alternatively with the travel plug adapter.
  • Travel plug adapters or travel plugs of this type are being used more and more in times of increasing global travel and business activity. Therefore, there is a need for compact, highly portable travel plug adapters that accommodate multiple standard outlets.
  • the Chinese patent application CN 101872911A discloses a travel plug adapter having a generally circular body.
  • Mains plugs are housed inside the housing, which can be selected and pushed out of the housing. At least three different mains plug types can be used in this way.
  • the desired mains plug is selected by twisting the upper part of the housing in relation to the lower part of the housing.
  • the upper part of the housing has a single outwardly projecting actuating slide. This operating slide can be brought into engagement with various mains plug elements. He does this by twisting into one position placed above the mains plug, which is to be pushed out of the housing at the bottom.
  • This travel plug may be useful for many purposes. However, it would be desirable to provide a travel plug that is even easier to use. In particular, it appears advantageous if different operating elements are assigned to different plugs, and the plug can be transferred into the use position directly by operating the assigned operating element. It should also be possible to return to a clearly recognizable and secure stand-by position.
  • the German patent DE 10 2011 014 920 B4 discloses another travel plug referred to as a universal plug adapter.
  • This travel plug several sets of plug pins are provided in an outer housing. Each pin set is connected to a control panel that allows it to be moved from the outside.
  • the controls are guided through sliding slots in the housing.
  • the controls are additionally guided through a locking plate provided within the outer housing.
  • This blocking plate has a connecting link through the recesses of which the operating parts can move.
  • the backdrop provides an upper and a lower end position.
  • the locking plate is spring-loaded so that a control panel can be held firmly in the upper or lower end position.
  • the control panel and thus the corresponding plug pin set can be released from the end positions and moved up or down by actuating a selector lever that is additionally provided on the outside next to the control panels. By pressing this selector lever, the locking plate is moved against the spring force. This allows the pins to be moved from their upper or lower end position using the controls.
  • the external controls are used both to move the pin sets from a first end position, a ready position, into a second end position, a use position, and to lock the pin sets in these positions.
  • the disadvantage of this is that while the sets of plug pins are being moved by the operating parts, the selector lever must also be operated. This stands in the way of convenient one-handed operation. Incidentally, the controls take up a lot of space on the connector surface. This stands in the way of free design-oriented design and the achievement of a compact design.
  • the object of the present invention is to provide an improved travel plug adapter that avoids the disadvantages of the prior art.
  • the travel adapter should be inexpensive and reliable to produce, easy to transport and operate, and offer a high level of electrical safety.
  • Claim 1 discloses the travel plug adapter of the invention.
  • the travel plug adapter according to the invention has a housing which can have different shapes. For example, a cuboid shape is usually convenient for transportation. However, the mechanics of the travel plug adapter are designed in such a way that the shape of the housing can be chosen freely. It is advantageous if the housing has at least one flat side, but the mechanism can also be adapted to curved housing surfaces.
  • the housing can be designed in one piece or in several pieces. It has proven to be expedient to design the housing in two parts, namely with a lower housing part and an upper housing part. Both can be detachably connected to one another, for example by mechanical means, expediently by a screw connection.
  • the housing should have at least one plug receptacle. This is expediently provided on the top of the housing. Depending on the type of mains plug to be plugged in (hereinafter referred to as: plug), the Plug receptacle have different shapes. If, for example, a Schuko plug is to be accommodated, the plug receptacle will have an essentially cylindrical recess and, in addition, contact sockets for accommodating the contact pins of the Schuko plug. Other connector types do not require a recess or pit. It may be appropriate to provide a flat housing top, in which several contact sockets are provided. As a rule, at least two contact sockets should be provided, which form a contact socket pair for receiving a plug of a standard.
  • the travel plug adapter should also have at least one plug of a first standard and a second plug of a second standard. (Such plugs are also sometimes referred to as pin sets.)
  • the first standard plug may be an EU plug and the second standard plug may be a US plug.
  • the plugs can be two-pole, ie ungrounded, or three-pole, so that a ground pole can be provided.
  • the present travel plug adapter is suitable for use in more than one country. It is expedient and usually also necessary if the first plug and the second plug are used alternatively.
  • the travel plug adapter can also include three or more plugs. Travel plug adapters with three or four plugs have proven to be very useful. At least one of the plugs, but usually all plugs, can be moved from a ready position, in which the plug is essentially in the housing, to a use position. In the use position, the plug is usable in its entirety or at least partially outside the housing. It is often possible for the plug to be moved completely back into the housing when it is returned to the ready position. It is expedient if the plug can be moved back into the housing at least far enough so that it does not get in the way of other plugs.
  • the first plug is connected to an actuating element for transferring it from the ready position to the use position.
  • the second plug is also connected to an actuating element for transferring it from the ready position to the use position.
  • the travel plug adapter thus has at least a first actuating element and a second actuating element.
  • the actuating elements can expediently be designed in the manner of buttons, so that they can be easily moved with a finger.
  • Sliding slots can be provided in the housing for the actuating elements. Sliding slots can also be connected to one another, resulting in a guide link for the actuating elements. As a rule, it is expedient to provide one sliding slot per actuating element and to arrange these sliding slots parallel to one another.
  • a selection slide can be provided on the travel plug adapter, which slide can be brought into at least a first position and a second position. Alternatively, in its first position, this selection slide releases the first plug or, in its second position, releases the second plug for transfer into the use position.
  • this selection slide has a blocking element; cams, for example, which engage in the displacement path, can serve as a blocking element. In the context of the present invention, however, it is not necessary to provide such a selection slide. It is optional and can be used in addition to the means described later.
  • the travel plug adapter should always be compact, the operating elements are usually close together.
  • the actuating elements are often designed as slides, which is why their function and advantages are explained below with regard to actuating slides. It can therefore easily happen that a finger, for example, is not placed exactly on the actuating slide, and an adjacent actuating slide could inadvertently be displaced as well.
  • the present invention only enables the actuation of one plug and thus (usually) also one actuating slide, the actuating slide accidentally touched does not move (or at least it does not move the associated plug). This makes the operation of the travel plug adapter more fault-tolerant.
  • the housing of the travel plug adapter has sliding slots or similar recesses.
  • the operating slides can run in these sliding slots.
  • a sliding slot for a selection slide can also be provided in addition.
  • Sliding slots allow movement of a slider while guiding it. They therefore represent an advantageous and inexpensive mechanical solution. Since, as a rule, several actuating slides are provided on the travel plug adapter, it is particularly advantageous if these can be guided in sliding slots in a simple manner. Within the scope of the present invention, the actuating slides only have to cause the plug to move, usually an up or down movement.
  • actuating slides do not have to ensure that the plugs are locked in the use position, nor do they have to ensure that only one plug can be selected at a time.
  • the operating slides are allowed to perform only one function within the scope of the present invention, they can be easily and reliably guided in sliding slots. If an actuating slide were spring-loaded, for example, the guide would be in a sliding slot in the Less user-friendly as a rule, the slide tended to jam, would run "notchy" and would have a higher resistance in any case.
  • a locking element is assigned to at least the first plug. This can be used to lock the plug in the ready position. The locking thus reduces the free displacement of the plug, in the ready position the resistance to a shift into the use position is then higher than in a middle position of the actuating element (a position between the ready position and the use position).
  • the locking element can assume an open position and a closed position, it being possible for the locking element to be transferred from the open position to the closed position by moving the first plug.
  • the locking element can be transferred from the open position to the closed position by moving the first plug.
  • the first plug is usually pushed up, ie in its ready position.
  • the additional actuation of a bolt or element for transferring the locking element into the closed position is not required.
  • the locking element is also transferred from the closed position to the open position by moving the first plug.
  • the additional actuation of a bolt or element for moving the locking element into the open position is then also not required. So that the element does justice to its function as a locking element, this transfer must take place at least against a resistance and can also be blocked in certain cases, for example if another plug is already in the use position.
  • the locking can be done by a selector slide or in some other way, for example by a locking mechanism.
  • the locking element ensures that the plug is locked in the ready position. If the travel plug adapter has only a first plug, a mechanism is provided for this that does not interact with other plugs. For example, a separate release lever could be provided. In certain embodiments, an element for resilient prestressing of the locking element into the closed position could also be provided.
  • the locking element ensures that there is a clearly defined ready position.
  • the user can, for example, cause two plugs to jam halfway into the use position by simultaneously actuating two actuating elements.
  • the locking element is designed as a component that is completely separate from the actuating element.
  • the locking element can be designed as a movable lever.
  • a tiltable lever is useful here, in particular a lever that tilts about a single axis of rotation, preferably an axis of rotation transverse to the direction of movement of the actuating element.
  • the lever can be spring-biased in the direction of its closed position; this can be provided as an alternative or in addition to another locking mechanism.
  • a travel plug adapter is expedient in which each plug is assigned a support element and in which the locking element acts on the support element, ie blocks it if necessary and thus locks the plug in the ready position.
  • the support element can, for example, be designed as a support arm which, on the one hand, carries the contact pins of the plug and, on the other hand, establishes a connection with the actuating element. It is particularly expedient if the support element has a depression and the locking element has a lug and the lug of the locking element can engage in the depression in order to hold the plug in the locked position. Such a lug at the end of the lever can be formed in a particularly simple and expedient manner.
  • the locking element can also be designed in other ways; many solutions are familiar to those skilled in the art in this area.
  • a mechanical solution is preferably selected; an electromechanical or friction-based or adhesion-based solution is also conceivable.
  • the locking element comprises a first unit, which is used to ensure that the transfer from the ready position to the use position takes place against increased resistance, preferably immediately after moving out of the ready position, but not along the entire displacement path.
  • the locking element can also include a second element, which serves to block the transfer to the usage position, for example because another plug is already in the usage position.
  • Mechanical locking elements can conveniently be designed using two interlocking elements. For example, a protrusion may engage a depression, a cam may engage a pit or recess, a pin may engage a guide, etc.
  • a travel plug adapter is expedient, in which a second plug of a second standard is also provided, which is also assigned an actuating element which is used to move the second plug between a ready position, in which the second plug is located essentially inside the housing, and a use position, in which the second plug is usably located outside the housing.
  • the second plug is assigned a second locking element, with which the second plug can be locked in the ready position and which in turn can assume an open position and a closed position.
  • the displacement paths of the first actuating element and of the second actuating element define a displacement plane.
  • the locking elements are expediently arranged behind this level. This allows a particularly compact design of the travel plug and prevents the mechanics of the actuating elements from affecting the mechanics of the locking elements. Moreover, it is perceived as optically more pleasing if the mechanism of the locking elements is not visible through the passages of the actuating elements through the connector housing, usually sliding slots.
  • the locking elements rotate around a pivot point behind the displacement axis.
  • rotary axes can be provided there, about which rocker arms rotate. Below the position "behind” the shift plane is a position toward the inside of the case to understand.
  • the locking elements are also arranged above the actuating elements and thus generally above the sliding slots (or corresponding to the housing openings).
  • the locking element of the second plug can be transferred from the open position to the closed position by moving the first plug.
  • This transfer can also consist of a mere fixation in the closed position.
  • the locking element then not only assumes the function of precisely defining the safety-relevant readiness position of the plug, but also ensures that the second plug is influenced by the position of the first plug.
  • the locking element can then take over the function that has, for example, rotating the connector housing to select a connector or the function that can have a selection slide in this context.
  • the at least one locking element are connected to a control lever which allows or blocks the transfer of the at least one locking element (or possibly all locking elements) into the open position.
  • the control lever or finger can be designed as a separate element and connected to the locking element or also be designed in one piece with the locking element.
  • a U-shaped lever has proven itself, one end of which has an element or, in particular, a lug that can interact with the plug or, in particular, with a support element of the plug. The other end of the U-shaped lever can then serve as a control lever or finger.
  • the blocking unit can expediently have at least one Have blocking carriage, which can be moved substantially parallel to the axis of rotation of the at least one locking element. It is expedient if the at least one blocking carriage (preferably all blocking carriages) is arranged on a displacement path. It is also expedient if the at least one blocking carriage is resiliently pretensioned towards one end of the displacement path. All of these measures related to the blocking unit bring about an effective interaction between the different plugs.
  • the location information (useful position or blocking position) is passed on to further control levers and thus to further locking elements via the position of the locking element and the control lever and then via the position of the locking carriage.
  • first blocking carriage of a first length and a second blocking carriage of a second length are provided.
  • the second length can be identical to the first length, but the second length can also be greater than the first length.
  • a greater second length makes it possible to design the distances between the different plugs unequally and even to choose them relatively freely, by means of adapted lengths of the blocking carriages, but to achieve reliable functioning of the blocking unit.
  • the plugs can be brought into the use position using the actuating elements.
  • Advantageous for the safe use of the Travel plug adapter is that the plugs also remain in the use position, for example when they are inserted into a socket against pressure.
  • a locking or latching element can be provided within the scope of the present invention. This locking element can lock at least one plug of the travel plug adapter, but the locking element can also lock several or all of the plugs in the use position.
  • the locking element is connected to a release button which is provided on the outside of the housing and can be actuated in a release direction.
  • a release button allows the intuitive and safe release of the latching element when a plug is to be transferred back from the use position to the ready position.
  • This construction appears safer and more reliable than those in which certain movements of the actuating element or a selection slide or the plug itself lead to the release of the plug.
  • the release button can also be provided with warnings or be designed in a warning color, for example red.
  • the release button can be part of the housing, for example if a part of the housing can be pressed in by means of a suitable design. As a rule, it is expedient to provide a recess in the housing and to provide the release button as a part independent of the housing in this recess.
  • the release button can expediently be arranged opposite the selection slide and/or the actuating slides.
  • the latching element is optionally resiliently prestressed against the release direction.
  • the resilient preloading of the latching element allows the reliable automatic latching of plugs into a detent as soon as the plugs are in the usage position. It is mechanically advantageous if the springs act exactly in the opposite direction to the release direction.
  • An expedient embodiment of an (optional) locking element is one in which the locking element has at least one locking bar and this locking bar has a sliding surface and a locking projection. An element that is connected to a moving plug can slide along the sliding surface. This element can then snap into place on the latching projection, so that the plug connected to the element is locked.
  • a travel plug adapter is expedient in which at least one plug has a sliding lug or is mechanically firmly connected to one and the sliding lug runs on the sliding surface and can optionally assume a locking position on a locking projection.
  • a travel plug adapter is also expedient in which the latching means has a large number of latching ribs, for example two, three or four latching ribs.
  • the number of locking webs can be as large as the number of plugs. It can also be expedient and sufficient if the number of latching webs is less than the number of plugs.
  • both plugs are each connected to a sliding lug and both sliding lugs run on the same locking web of the locking element. Since both slide lugs run on the same latching web, both slide lugs run on the same sliding surface and on the same latching projection on which both slide lugs can assume a locking position. Since two plugs are not to be transferred into the use position at the same time in the travel plug adapter, the sliding lugs alternatively assume this locking position on the locking projection. But by two sliding lugs, for example two sliding lugs of adjacent plugs, share a suitably sized latching web, the number of Locking bars are reduced and the travel plug adapter can be built even more compactly.
  • FIG. 1 shows a perspective view of a travel plug adapter 10 according to the invention, which is ready for use but is not yet in the use position. Rather, all plugs are in the ready position, ie in the housing.
  • the travel plug adapter has a housing which consists of an upper housing part 12 and a lower housing part 14 .
  • the upper housing part 12 and the lower housing part 14 together form the main connector housing.
  • the plug receptacle 16 is located on the upper side of the travel plug adapter and thus in the area of the upper housing part 12 . It has a large number of contact sockets 18 .

  • FIG. 2 shows a perspective view of the embodiment of the travel plug adapter according to the invention, in which the actuating slide 22 has been transferred to its lower position. Accordingly, the contact pins for the US plug 28 protrude from the housing.
  • the US plug 28 includes two live contact pins, pins 30A and 30B, and a grounding pin 32. In the position shown, the travel plug is suitable for insertion into a US standard outlet. This standard does not require that a connector body be used. The underside of the housing of the travel plug adapter 10 then lies flush on the flat surface of the US standard plug.

  • ground contacts 44 are located on the sides of the plug body.
  • figure 5 shows a perspective view of selected interacting components of the travel plug 10. With the upper part of the housing removed, the view goes into the interior of the plug, so essentially the components that are accommodated by the lower part of the housing 14 can be seen. It should also be noted that not all components required for the function of the connector are shown. A selection has been made for the sake of clarity.
  • the openings 36A and 36B are provided for the current-carrying contact pins of the Schuko plug.

  • Another opening can also be seen in this representation, the opening 56 for the ground pin of the AU plug.
  • the conductive pins 30A and 30B for the US plug are in their ready position, ie they have been withdrawn into the housing. Accordingly, the first actuating slide 22 is in the upper position. The actuating slide 22 can be held in this position by the locking mechanism 48 .
  • the actuating slide 22 moves the supporting beam 50.
  • the contact pins 30A and 30B are suspended on this supporting beam 50. Accordingly, when the first actuating slide 22 is displaced, the supporting beam 50 moves downwards in the direction of the bottom of the housing.
  • the contact pins 30A and 30B are guided in the plug body 40 of the Schuko plug.
  • the Schuko plug thus offers a guide for contact pins of a different standard.

  • Beam ends 54A and 54B support the current conducting contacts of the AU plug. They mechanically guide these contacts from the ready position (shown) to the use position.
  • Beam end 54C carries the AU ground pin. The ground pin is thus removed from the ready position (shown) by the in figure 5 visible opening 56 transferred to the use position.
  • FIG. 7 shows selected components in a perspective view, from which an embodiment of a locking mechanism useful within the scope of the present invention can be recognized.
  • Three actuating elements are shown in the form of a first actuating slide 84 for a US plug, in the form of a second actuating slide 86 for a UK plug and in the form of a third actuating slide 88 for an AU plug.
  • the locking mechanism 90 shown can also interact with other plugs, for example the one shown in 1 arrangement shown.
  • the locking mechanism 90 in turn comprises a sliding track 92 as one element. This sliding track 92 extends between the first end piece 94 and the second end piece 96.
  • a spring 98 is provided adjacent to the first end piece 94, which is suitable for moving the various blocking carriages to the second End piece 96 of the sliding track 92 to be resiliently biased.
  • the spring 98 is arranged in the first blocking carriage 100A. It also acts (through this carriage) on the second blocking carriage 100B and on the adjacent third blocking carriage 100C.
  • the blocking carriages are each equipped with guide cheeks, the guide cheeks 102A, 102B and 102C. Furthermore, inclined surfaces are provided at the ends of the blocking slides, the inclined surfaces 104A, 104B and 104C.
  • Rocker levers are arranged above the sliding path 92 . Each actuating element and thus plug is assigned its own rocker arm. Rocker arm 106A is associated with actuator 84 , rocker arm 106B is associated with actuator 86 , and rocker arm 106C is associated with actuator 88 . The rocker arms rotate about an axis of rotation (not shown) below the travel path 92. The axes of rotation are substantially parallel to the travel path 92. Each rocker arm has a control finger 108 integrally formed therewith. For the sake of clarity, this is only identified for the rocker arm 106C. A locking cam 110 is provided opposite the control finger 108 . The locking cam can engage with the associated actuating element and fix it in the ready position. The mechanics involved are explained in more detail in connection with the figure below.
  • the rocker arm 106C is in a lower position. In this position, the control finger 108 is located directly above the sliding track 92. The control finger can only reach this position if a suitable gap is created between the blocking carriage 100C and the second end piece 96. The control finger 108 engages in this gap.
  • the guide cheek 102C and the inclined surface 104C ensure that when the rocker arm 106C moves, the control finger 108 can reliably enter this gap.
  • the gap is just dimensioned so that after dipping a control finger It is no longer possible to move the blocking slides 100A, 100B or 100C. This also applies accordingly to the control fingers of the other rocker arms.
  • rocker arm 106C When the rocker arm 106C is moved to its upper position, which corresponds to the ready position of the actuating slide 88, in which the control finger 108 is located above the blocking carriage 100C, there is room for the displacement of all three blocking carriages. Accordingly, the rocker arm 106B associated with the actuating slide 86 could then be moved to a lower position. In doing so, his control lever, guided by the guide cheek 102B and the inclined surface 104B, would push the blocking carriage 100C away to the right onto the second end piece 96. This would be possible, however, since a gap would be available there due to the corresponding position of the rocker arm 106C.
  • FIG. 8 shows the in from a different perspective 7 selected components of one embodiment shown, and again the actuator slides 84, 86 and 88.
  • the actuator slides 84 and 86 and the corresponding plugs are in the ready position.
  • the operating slide 88 and the corresponding plug are in the use position. Only the parts that are essential for the description of how the rocker arms work have been identified.
  • the locking cam 110C can engage in a corresponding engagement 112C on the actuating slide 88.
  • Such an engagement can generally expediently be designed as a groove.
  • a counter cam 114C is additionally provided on the actuating slide.
  • the counter cam 114C presses against the pressure surface 116C on the rocker arm 106C. This causes rocker arm 106C to move back to its up position. In doing so, the locking cam 110C engages in the engagement 112C. This creates a positive connection that keeps the actuating slide 88 in the upper position.
  • the rocker arm could also be spring-loaded to run regardless of the position position of a blocking carriage to hold securely. However, as soon as the blocking carriage 100C is displaced and the position of the rocker arm 106C is fixed via the control finger 108, the actuating slide 88 is held securely and firmly in its upper position.
  • the locking cam 110B is fixedly connected to the catch 112B of the operating slide 86.
  • the counter cam 114B engages the rocker arm.
  • the blocking carriage 100C prevents the control lever 108B and thus the rocker arm 106B from being able to move downwards as a whole.
  • a travel adapter can be produced which is very easy to use, but in which operating errors are hardly to be expected.
  • the travel adapter can still be manufactured inexpensively in this way and can also be manufactured inexpensively and reliably, even if greater error tolerances have to be allowed for in mass production.
