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 certain (domestic) standard can be plugged into the sockets there at the travel location.
  • the travel plug adapter requires a plug receptacle of the first standard or an alternative power supply (e.g. via a cable) and a power plug of another standard.
  • it is more precisely about travel plug adapters, which enable the plugging into sockets of at least a first and a second standard.
  • mains plugs of a first and a second standard can alternatively be used with the travel plug adapter.
  • Travel plug adapters or travel plugs of this type are used more and more in times of increasing global travel and business activity. There is therefore a need for compact, easily transportable travel plug adapters that are suitable for sockets of several different standards.
  • the Chinese patent application CN 101872911 A discloses a travel plug adapter with a substantially round housing. Power plugs 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 plug can be used.
  • the desired power plug is selected by rotating the upper part of the housing relative to the lower part of the housing.
  • the upper housing part has a single outwardly projecting operating slide. This actuating slide can be brought into engagement with various mains plug elements. To do this, it is turned into a position brought above the power plug to be pushed out of the housing below.
  • 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 and that can also have a cuboid shape.
  • the German patent specification DE 10 2011 014 920 B4 discloses another travel plug, which is 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 unit with which it can be moved from the outside.
  • the control units are guided through sliding slots in the housing.
  • the control units are additionally guided through a locking plate provided inside the outer housing.
  • This locking plate has a backdrop through which the control panels can move.
  • the backdrop provides an upper and a lower end position.
  • the locking plate is resiliently biased so that an operating part can be held firmly in the upper or in the lower end position.
  • the control unit and thus the corresponding pin set can be released from the end positions and moved up or down by actuating a selector lever additionally provided on the outside next to the control units. Pressing this selector lever moves the locking plate against the spring force. This allows the pins to be moved from their upper or lower end positions using the control panels.
  • the outer operating parts are used both to transfer the pin sets from a first end position, a standby position, to a second end position, a use position, and to lock the pin sets in these positions.
  • the disadvantage of this is that during the movement of the pin sets by the control panels the selector lever must also be operated. This stands in the way of convenient one-hand operation. 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 Chinese patent application CN105576408A1 discloses a travel plug adapter which has a selection slide for selecting plugs of different standards. Four actuating slides are arranged opposite. However, the provision of a large number of such actuation slides in the model presented means that one side of the housing is quite open, so that dirt can penetrate, for example. This is not conducive to the robustness of the adapter or the electrical safety.
  • the U.S. Patent 7,220,139B1 discloses a travel plug adapter which has a slotted link in the housing wall. An actuating slide can be moved in this setting. Depending on the position of the actuating slide in the backdrop, various plugs are pushed out of the housing so that they can be used. This type of actuation in turn has the disadvantage that a housing side must be designed to be relatively open. In addition, many users will find moving the actuating slide within the setting not user-friendly.
  • the object of the present invention is to provide an improved travel plug adapter which avoids the disadvantages of the prior art.
  • the travel adapter should be inexpensive and reliable to manufacture, easy to transport and operate and offer high electrical safety. It should also be compact and robust.
  • the travel plug adapter according to the invention has a housing which can have different shapes.
  • a housing which can have different shapes.
  • the mechanics of the travel plug adapter are designed so that the housing shape can be largely freely selected. 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 or more parts. 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 releasably connected to one another, for example by mechanical means, expediently by means of a screw connection.
  • the housing should generally have at least one connector receptacle. This is expediently provided on the top of the housing. Depending on the type of power plug to be plugged in (hereinafter briefly: plug), the plug receptacle can have different shapes. If, for example, a Schuko plug is to be received, the plug receptacle will have a substantially cylindrical recess and, moreover, contact sockets for receiving the contact pins of the Schuko plug. A recess or pit is not required for other connector types. It may be expedient to provide a flat top of the housing 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.
  • plugs may be expedient to provide several pairs of contact sockets in order to be able to accommodate several plugs of different standards. If the plugs also have ground conductors and the plug receptacle is to offer the possibility of grounding, it is usually necessary to provide a third contact socket or a third contact for each plug to be accommodated.
  • Housings without a plug receptacle are also conceivable.
  • a power supply can take place, for example, via cables.
  • Such an embodiment can also be referred to as a connector.
  • she can Applications that go beyond those of a travel plug adapter.
  • the housing of the connector can be separate or integrated into the housing of another device. Accordingly, the plug can sit at the end of an electrical cable or can be extended directly out of the housing of an electrical device.
  • 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 sometimes also referred to as pin sets.)
  • the plug of the first standard can be an EU plug, for example, and the plug of the second standard can be a US plug.
  • the plugs can be two-pole, that is, ungrounded, or three-pole, so that an earth pole can be provided.
  • the present travel plug adapter is therefore suitable for use in more than one country. It is expedient and generally also necessary if the first connector and the second connector are used alternatively.
  • a plug in the sense of this application essentially consists of contact pins.
  • at least two contact pins are provided (as positive and negative poles), and a third contact pin can also be provided, which then usually serves as an earth contact.
  • the contact pins usually have some form of mechanical limitation of the insertion depth. This can be a connector plate, for example, as described below.
  • Some plugs also have a plug body, for example a Schuko plug has an essentially cylindrical plug body.
  • the travel plug adapter can also comprise 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 as a rule all plugs, can be brought from a standby position, in which the plug is essentially in the housing, to a use position.
  • the plug 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 when it is returned to the ready position. It is expedient that the plug can be moved back into the housing at least so far that it is not in the way of other plugs.
  • At least one first actuating slide is provided on the travel plug adapter, which is used to move the first plug or the second plug between the ready position and the use position.
  • the first actuating slide should run in a guide slot in the housing.
  • the first actuating slide is also intended to act on a movable coupling element, the movable coupling element alternatively being able to act on the first connector or on the second connector, so that the first actuating slide can alternatively transfer the first connector or the second connector from the ready position to the use position.
  • only one actuating slide is provided for moving two plugs.
  • the coupling element is moved perpendicular to the guide slot. This allows the coupling and decoupling of different elements by a particularly short displacement of the coupling element. It is expedient if the movement of the coupling element perpendicular to the guide slot is decoupled from the movement of the actuating slide.
  • a guide plate can be provided on which the coupling element is guided.
  • the coupling element can be displaceable parallel to the guide plate. In this way, the coupling element can perform a coupling or decoupling movement without the guide plate moving.
  • the actuating slide or slides can then act on the guide plate. This will cause the movement of the coupling element decoupled from the movement of the actuating slides at right angles to the guide rails.
  • the guide rails can be designed closely.
  • the actuating slide or slides can be firmly connected to the guide plate.
  • the actuating slide (s) act mechanically on the guide plate such that the guide plate can be moved back and forth between the use position of the travel plug adapter and the ready position of the travel plug adapter.
  • the coupling element is further moved between a first coupling position and a second coupling position by a selection element provided on the outside of the housing.
  • the first coupling position allows the first connector to act and correspondingly be transferred from the ready position to the use position
  • the second coupling position can act on the second connector and correspondingly be transferred from the ready position to the use position.
  • the coupling element should decouple / release the second and possibly further connectors in the first coupling position. Accordingly, the coupling element should generally decouple / release the first and possibly further connector in the second coupling position.
  • each plug has a number of contact pins which are arranged on at least one support element.
  • the support elements have first connecting elements and these can mechanically engage with corresponding second connecting elements on the coupling element. This means that a mechanical coupling can be established or released between the first and the second connecting elements. This allows decoupling between the support elements and the coupling elements getting produced.
  • This in turn means that alternatively at least one support element of the first connector or at least one support element of the second connector can be coupled to the coupling element.
  • the at least one actuating slide can then also act on the first connector or on the second connector via the coupling element.
  • the first connecting elements which are provided on the support elements, can expediently be designed as guide lugs.
  • the second connecting elements which are provided on the coupling element, can expediently be designed as guide slots.
  • Other known mechanical solutions are also suitable, such as cams that run in channels or the like.
  • the travel plug adapter also has a second actuating slide, which is designed to move the first plug or the second plug between the ready position and the use position. It would be conceivable that the first actuating slide as well as the second actuating slide can act on both plugs simultaneously. As a rule, however, it makes sense that, alternatively, only the first connector or the second connector is transferred to the use position. It is therefore expedient if the actuating slides only act on one plug at a time. If two actuating slides are provided, it is usually safer and more convenient to move a plug into the use position. Less force is to be used per actuating slide than if only actuating slides are provided.
  • first actuating slide and the second actuating slide are opposite one another. It is particularly expedient if the actuating slides are arranged symmetrically with respect to a mirror plane of the housing.
  • the travel plug adapter will often have a central plane, which lies between the plus and minus poles of the plug. It makes sense to arrange the actuating slides mirror-symmetrically with respect to this central plane.
  • the second actuating slide also runs in a guide slot in the housing.
  • a travel plug adapter which has an essentially cuboid housing, is also expedient.
  • a housing is easy to handle and transport for the user as well as very advantageous for storage and trading.
  • a square housing often allows to accommodate plugs of different standards in a particularly space-saving manner, since the plug standards often provide a contact pin arrangement which can be arranged compactly on a rectangular base area.
  • first guide slot and the second guide slot are arranged centrally on a housing wall.
  • the arrangement in the central third of the housing wall surface is advisable. This is always very useful if the housing of the travel plug adapter has two opposite and essentially parallel walls.
  • the travel plug adapter has a two-part housing. This is favorable for production and also for the stability of the Housing. Accordingly, the travel plug adapter then has an upper housing part and a lower housing part.
  • a travel plug adapter has proven to be particularly stable if the upper housing part and lower housing part are firmly connected to one another. They are then not rotatable or slidable against each other. This allows the formation of a stable housing, which meets all requirements of electrical safety even after prolonged use.
  • the guide slots only in the lower housing half in the case of a housing with an upper housing part and lower housing part.
  • the lower half of the housing is the one from which the plugs are pushed out. Since the upper half of the housing has no guide slots, it can be made particularly stable. The lower half of the housing can easily be dimensioned so that enough space can be provided for guide slots.
  • 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 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 projections below the guide plate 90 produce a form-fitting mechanical connection which prevents the central web from being detached upwards. Movement in the left-right direction is likewise impossible through the groove 91 as well as the clips 96.
  • This sectional view also shows clearly how the actuating slides 20 and 22 are connected to the guide plate by connecting brackets 98 and 98 '.
  • the connecting brackets encompass the guide plate on the side and establish a mechanical connection, in particular with the underside of the guide plate.
  • a travel adapter can be produced which can be operated comfortably and safely and at the same time allows a compact design.
  • the travel adapter can still be manufactured inexpensively in this way.
