  • 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 transportable travel plug adapters that are suitable for sockets of several different standards.
  • the Chinese patent application CN 10187291 1 A discloses a travel plug adapter 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 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.
  • plug adapters With both plug adapters from these disclosures, as with other commercially available plug adapters, high electrical safety is important. In particular, the reliable grounding of the plug adapter plays a role. The plug adapters are grounded regularly when a selected plug is completely transferred to its use position. It is conceivable however, that a user-damaging electrical contact already comes about before.
  • Object of the present invention is to provide an improved travel plug adapter available.
  • the travel adapter should be inexpensive and reliable to produce, easy to transport and operate and provide high electrical safety.
  • the travel adapter according to the invention avoids, despite very compact design, that this is grounded only in the use position and neither in the ready position nor in transition positions between standby position and use position.

  • 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.

If, for example, a Schuko plug is to be accommodated, the plug receptacle will have a substantially cylindrical depression and, in addition, contact sockets for holding 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.
  • connectors may be appropriate to provide multiple pairs of female contact to accommodate several plugs of different standard. If the connectors also have earth conductors and the plug receptacle is to offer the possibility of earthing, then it is usually necessary to provide a third contact socket or a third contact per plug to be picked up.

In the Useful 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.

With its two contact jaws 86A and 86B may slide the movable end 82 along the first contact rail 72 while maintaining electrical contact, and the corresponding sliding along occurs as the ground contact 64 slides downwardly from the ready position to the use position upon transfer of the corresponding plug in the context of the present invention expedient to provide two opposite contact jaws at both ends of a contact clip, but in particular at its movable end.

Consequently, the second contact strip 74 carries two contact clips. This is generally within the framework of present invention, a useful concept. It is also useful in the context of the present invention, when the movable end of a first contact clip (here the clip 78) and the fixed end of a second contact clip (here the clip 80) are connected to a contact pin.

Interestingly, the travel adapter can still be produced inexpensively in this manner and can also be produced inexpensively and reliably, even if larger fault tolerances must be permitted in mass production.
