Definitions

  • the present invention relates to a travel plug adapter, which is also referred to herein briefly as a travel plug.
  • a travel plug adapter With the help of such an adapter, power plugs of a specific (domestic) standard can be plugged into the existing outlets at the place of travel.
  • the travel plug adapter requires a plug receptacle first standard and a power plug of another standard.
  • it is more accurate to travel plug adapters that allow plugging into sockets at least a first and a second standard.
  • mains plug of a first and a second standard can be used alternatively.
  • Travel plugs or travel plugs of this type are increasingly used in times of increasing global travel and business. There is therefore a need for compact, well portable travel plug adapters that are suitable for power outlets of several different standards.
  • the Chinese patent application CN 10187291 1 A discloses a travel plug with a substantially round housing. Housing connectors are housed inside the housing, which can be selected and pushed out of the housing. In this way, at least three different types of power connectors can be used.
  • the selection of the desired power plug is done by the upper housing part is rotated relative to the lower housing part.
  • the upper housing part has a single outwardly projecting actuating slide. This actuating slide can be brought into engagement with different power plug elements. It is brought by twisting into a position above the outwardlySchebenden from the housing power plug.
  • This travel plug adapter may be useful for many purposes.
  • the mechanical rotation of the upper housing part relative to the lower housing part requires a precise housing manufacturing to allow a low-resistance rotational movement and also to ensure that the Actuating slide in different housing positions can be reliably brought into engagement with a power plug element.
  • the round shape itself is a limitation. In many cases, for example, a cuboid travel plug adapter is perceived as easier to transport. Furthermore, you do not have all the selectable power plug elements in view from a certain angle with a round travel plug adapter.
  • the German patent DE 10 201 1014920 B4 discloses another travel plug adapter, which is referred to as a universal plug adapter.
  • this travel plug adapter several plug pin sets are provided in an outer housing. Each pin set is connected to a keypad with which it can be moved from the outside.
  • the controls are guided through sliding slots in the housing.
  • the control units are additionally guided by a provided inside the outer housing locking plate.
  • This locking plate has a backdrop through which recesses, the controls can move.
  • the scenery provides an upper and a lower end position.
  • the locking plate is resiliently biased so that a control panel can be held firmly in the upper or in the lower end position.
  • control panel and thus the corresponding pin set can be released from the end positions and moved up or down by an externally provided next to the controls additionally provided selector lever is actuated. By pressing this selector lever, the blocking plate is moved against the spring force. This allows the pins to be moved from their upper or lower end position using the keypads.
  • the outer keypads are used both to transfer the pin sets from a first end position, a standby position, to a second end position, a use position, as well as to lock the pin sets in these positions.
  • the disadvantage of this is that during the movement of the pin sets by the controls in addition the selector must be operated. This is a convenient one-handed operation in the way. Furthermore, the operating parts in the sliding slots do not run freely because the resiliently biased locking plate constantly presses against the operating parts during the movement. While the selector lever is being operated, it would also be possible to transfer two pin sets into or at least in the direction of the useful position as a result of incorrect operation.
  • the object of the present invention is to provide an improved travel adapter which avoids the disadvantages of the prior art.
  • the travel adapter should be inexpensive and reliable to produce, easy to transport and operate and provide high electrical safety.
  • 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 transport.
  • the mechanics of the travel plug adapter is, however, designed so that the housing form can be chosen largely 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 made in one piece or in several parts. It has proved to be expedient to carry out the housing in two parts, namely with a housing lower part and a housing upper part. Both can be releasably connected to each other, for example by mechanical means, expediently by a screw connection.
  • the housing should have at least one connector receptacle. This is expediently provided on the housing top.
  • the plug receptacle may have different shapes. If, for example, a Schuko plug is to be accommodated, then the plug receptacle will have a substantially cylindrical depression and, in addition, contact bushes for receiving the contact pins of the Schuko plug. Other types of plugs do not require a pit or pit. It may be expedient to provide a flat housing top, in which a plurality of contact sockets are provided. As a rule, at least two contact sockets should be provided, which form a pair of contact sockets for receiving a plug of a standard.
  • the travel plug adapter should further comprise at least one plug of a first standard and a second plug of a second standard. (Such connectors are sometimes referred to as pin sets.)
  • the plug of the first standard may be, for example, an EU plug and the plug of the second standard to a US plug.
  • the plug can be bipolar, that is ungrounded, or even three-pole, so that a ground pole can be provided.
  • the present travel plug adapter is therefore suitable for use in more than one country.
  • the travel plug adapter may 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 generally all the plugs, can be brought from a standby position, in which the plug is located substantially in the housing, into a use position. In the use position, the plug is usable completely or at least partially outside the housing. It is often possible for the plug to be completely moved back into the housing during the return to the ready position. It is expedient that the plug can at least be moved back into the housing so far that it is not in the way of other plugs.
  • the first plug is connected to an actuating slide for its transfer from the ready position to the use position.
  • the second plug is also connected to an actuating slide for its transfer from the ready position to the use position.
  • the travel plug adapter has at least a first actuating slide and a second actuating slide.
  • the actuating slide can be conveniently carried out like a button, so that they can be easily moved with a finger.
  • Sliding slots can be provided in the housing for the actuation slides. You can also connect sliding slots together, so that there is a guide link for the operating slide. It is expedient, as a rule, to provide one slide slot per actuation slide and to arrange these slide slots parallel to one another.
  • a selection slide is provided, which can be brought at least in a first position and a second position. This selection slide is alternatively in its first position, the first connector or in its second position the second connector for transfer to the use position free.
  • the selection slider offers a practical added value for the travel plug adapter. Not infrequently, a travel plug adapter is carried several times in the same destination country. It is also contemplated that in a destination country, the required plug from the use position is returned to the standby position while it is not needed. It is therefore advantageous if the corresponding plug type can be set on the selection slide. It is easily possible to label the selection slider in such a way that the destination country can be easily read and adjusted there. After the selection slide is then transferred to the appropriate position, only the corresponding plug can be transferred to the use position. This usually means that only one operating slide can be moved.
  • the actuators are usually close together. It may therefore be easy that about a finger is not placed exactly on the actuating slide, and an adjacent actuating slide could be accidentally moved along. Since the present invention but only the operation of a plug and thus (usually) also an actuating slide is made possible, the accidentally mitzurindt actuating slide does not move (or he does not move at least the associated connector). This makes the operation of the travel plug adapter more forgiving.
  • a selector slide which releases only a plug and an actuating slide also has considerable safety advantages. If more than one plug is pushed out at the same time, current can flow through other than the standard-compliant contacts. This can damage the travel plug adapter and, in the worst case, damage to connected devices or even a user.
  • the plugs can be brought into the use position by means of the actuating slide. Of importance for the safe use of the travel plug adapter is that the plug remain in the use position, for example, even if they are introduced against pressure in a socket.
  • a locking or locking element In order to secure the whereabouts of plugs in the use position and to lock them there may be provided in the context of the present invention, a locking or locking element.
  • This latching element can lock at least one plug of the travel plug adapter, expediently, the latching element can also lock several or all plugs in the use position.
  • the locking element is expediently designed as a separate component from the selector slide.
  • the design as a separate component has manufacturing advantages.
  • the selector slide is a component that does not have to transmit large forces or has to withstand large forces. By its nature, the locking element must, however, apply sufficient force to reliably hold a plug of any standard in the use position.
  • the locking element is also a separate component from the operating slide.
  • the locking element is to be understood as a separate component if it has at least one component which is not part of the selection slide or an actuating slide. It is expedient in most cases when all components of the locking element are designed separately from the components of the selection slide and also the components of the actuating slide.
  • release button which is provided on the outside of the housing and to operate in a release direction.
  • Such release button allows the intuitive and safe release of the locking element when a plug is to be transferred from the use position back to the ready position.
  • This construction appears safer and more reliable than those in which certain movements of the actuating slide or the selection slide or even the plug itself lead to the release of the plug.
  • the release button is not accidentally pressed, it can also with warnings be provided or in a warning color, for example in red, be designed.
  • the release button may be part of the housing, such as when a part of the housing can be pressed by suitable design. In general, it is expedient to provide a recess in the housing, and to provide the release button as independent of the housing part in this recess.
  • the release button opposite to the selector slide and / or the actuators are arranged.
  • the latching element is resiliently biased against the release direction.
  • the resilient biasing of the locking element allows the reliable automatic engagement of plugs in a lock when the plug is in the use position. It is mechanically advantageous if the springs act exactly opposite to the release direction.
  • An expedient embodiment of a latching element is one in which the latching element has at least one latching web and this latching web has a sliding surface and a latching projection. On the sliding surface, an element connected to a moving plug can slide along. This element can then engage the latching projection, so that the connector connected to the element is locked.
  • a travel plug adapter in which at least one plug has a sliding nose or is mechanically fixedly connected to such and the sliding nose runs on the sliding surface and can assume a locking position on the latching projection.
  • the locking means comprises a plurality of locking webs, for example, two, three or four locking webs.
  • the number of locking bars can be just as large as the number of plugs. Appropriate and sufficient, it may also be, if the number of locking webs is less than the number of plugs.
  • both plugs are each connected to a sliding nose and both slide lugs run on the same latching web of the latching element. Since both Gleitnasen run on the same locking bar, so run both sliding lugs on the same sliding surface and the same locking projection on which both slide lugs can assume a locking position. Since in the travel plug adapter not two plugs should be transferred simultaneously to the use position, the sliding lugs take alternatively this locking position on the locking projection. But by two Gleitnasen, for example, two sliding lugs adjacent plugs, share a suitably sized locking bar, the number of locking bars can be reduced and the travel plug adapter be built so compact.
  • the selector slide can be provided in any suitable form within the scope of the present invention. He will usually allow in a mechanical way, the movement of only one plug and prevent the movement of the other plug. Conveniently, the selector slide can act on the actuating slide, which are connected to the respective plugs. It may also be expedient if the selector slide acts on another element connected to the plugs.
  • the selector slide may comprise a selector slide body. This can be placed inside the housing of the travel plug adapter. It is expedient to then provide a recess in the housing, which allows the operation of the selection slide. For example, an actuation button, which is also referred to as a selector slide button below, be accessible through the recess. It is also conceivable that the selection slider body is placed outside the housing, and it acts on the outside of the housing on the actuating slide or acts by means of a passage inside the operating slide.
  • At least one plug or all plugs can be connected to an engaging element, which cooperates with the selector slide so that the transfer of the plug is prevented in the use position.
  • the engaging element may be designed as a cam or generally as a projection.
  • the movement of the engagement element can be prevented by a blocking element of the selection slide, for example by a locking bar, a locking cam or the like.
  • the arrangement of the locking cam in series, so that the cams form a comb-like locking bar.
  • the blocking element can advantageously have recesses which allow the passage of the engaging element. For example, a number of projections and recesses may be provided on the selector slide.
  • the housing of the travel plug adapter has sliding slots.
  • the actuators can run in these slide slots. It may also be additionally provided a sliding slot for the selection slide.
  • Slide slots allow the movement of a slider while guiding. They thus represent an advantageous and inexpensive mechanical solution. Since usually several actuation slides are provided on the travel plug adapter, it is particularly advantageous if they can be guided in a simple manner in sliding slots. In the context of the present invention, the actuating slide only the movement of the plug, usually cause an up or down movement. The actuating slide must provide neither for the locking of the plug in the use position, nor cause that only one plug can be selected. Inasmuch as the actuators in the present invention are allowed to perform one function only, they can be easily and reliably guided in slide slots. If an actuating slide, for example, spring-loaded, the guide would be in a sliding slot usually less user-friendly, the slide was prone to tilting, would be "hooked" and would certainly have a higher resistance.
  • a locking element can be provided.
  • the locking element is provided on the selector slide or connected thereto.
  • Lock element and selector slide can represent a single component or at least one connected overall component.
  • a locking element which has a first functional element for interacting with the first connector and a second functional element for interacting with the second connector.
  • first functional element and the second functional element are identical.
  • the first functional element and the second functional element can each be made available from identical components or similar component sections.
  • the locking element has fingers, which can engage firmly connected to the housing recordings.
  • the functional elements can be conveniently carried out in the form of fingers.
  • the locking element may also have projections or cams instead of fingers.
  • the recordings may be designed, for example, as projections or recesses in a detent gate.
  • the receptacles could also be designed as recesses or holes in the housing or in a component connected to the housing.
  • the locking element comprises a spring element. It is even possible if the locking element is formed entirely of a spring element, such as a leaf spring. The fingers of the locking element can be resiliently biased by means of such a spring. The direction of the spring force goes into the recordings on the housing. The projection of the springs into the corresponding receptacles is prevented as long as all the plugs are in the ready position.
  • the spring element of the locking element resiliently biases its fingers in the direction of the receptacles connected to the housing for the fingers.
  • the engagement of the fingers in the corresponding recordings can then be conveniently prevented by firmly connected to the connectors elements, as long as the plug are in the ready position.
  • parts of the actuating slide take on this task.
  • the actuating slide can be connected to sliding surfaces, which slide in the transfer of the operating slide in the use position on the fingers, but release them in the use position, so that the Actuator assigned fingers immersed in a finger associated recording.

  • the fingers 58A, 58B, 58C and 58D of the latch member 56 conform to the housing top. All fingers are shown in the ready position. As soon as an assigned actuating slide and the corresponding plug are transferred to its position of use, a finger moves into the locked position. In order to effect the locking of the finger in the latch position, the locking link 62 is provided on the housing bottom. This locking link has recesses. In the embodiment shown, the recesses are separated by webs of adjacent recesses. The locking link 62 has a total of four recesses, the recess 64A, the recess 64B, the recess 64C and the recess 64D.
  • locking linkage may also be appropriate, in general, the locking link to the housing should have fixed finger holders. As soon as a finger 58 dips into an associated recess 64, takes the locking element 56 a stationary position to the housing. It can thus no longer be displaced together with the selector slider body 44, in the viewing direction the relevant displacement is blocked upwards or downwards.

  • the locking element 66 has the already known release button 40. It also has a chassis 68.
  • the chassis 68 is equipped with unspecified mounting clips that allow the attachment of the locking element 66 to other elements of the travel plug adapter.
  • the latching element 66 also has three latching webs, the first latching web 70A, the second latching web 70B and the third latching web 70C.

  • the plug body 32 is further connected to a slide nose 72.
  • the sliding lug can slide along the first latching web 70A and can assume a locking position at the lower end of the first latching web 70A.
  • Fig. 14 shows the known from Fig. 13 elements, but this time in a side view, from which the exact operation can be seen even better.
  • the first latching web 70A (as well as the remaining latching webs) has a sliding surface 74 and a latching projection 76.
  • the slide nose 72 of the plug body 32 can slide along.
  • the locking element 66 is laterally movable, ie in the predetermined by the orientation of the release button 40 release direction (in this view a Direction from right to left).
  • the latching element 66 is resiliently biased so that the slide nose 72 is pressed against the sliding surface 74.
  • the sliding nose 72 When the plug body 32 reaches its use position, the sliding nose 72 reaches the latching projection 76. Since the latching element 66 is spring-biased (such that it is thereby pushed to the right in this illustration), the slide nose 72 moves under the latching projection 76 and is thus locked , This locking is mechanically very favorable, since the latching web 70A is loaded along its main extension direction and thus essentially has to absorb only compressive forces. By pressing the release button 40, however, the lock can be reliably released, and the plug body can be moved back along the sliding surface 74 in its standby position.
  • a travel adapter can be produced which can be operated very comfortably, but in which incorrect operation is scarcely to be expected.
  • the travel adapter in this way is still inexpensive to produce and can also be produced inexpensively and reliably, even if larger error tolerances must be allowed in mass production.
