This application claims the benefit under 35 USC §119(a)-(d) of German Application No. 10 2009 016 825.7 filed Apr. 9, 2009, the entirety of which is incorporated herein by reference.
The invention relates to an adapter for a micro USB socket or a mini USB socket, and to an arrangement comprising a mobile device, a mount and an adapter.
The prior art discloses adapters in which a micro USB plug contact is converted into a USB-A socket contact, with a gripping body being arranged between the contacts. Furthermore, DE 198 35 017 C2 discloses an arrangement comprising a mobile device, a mount and an adapter, in which arrangement the adapter is in the form of a block with plug contacts which project in the direction of the mount.
One object of the invention is to provide an adapter which is suitable for use in mobile devices and, in particular, is also suitable for being used with the mobile device when the mobile device is inserted into a mount. A further object of the invention is to provide an arrangement in which the adapter can remain permanently in the mobile device.
In the adapter according to the invention for a micro USB socket or a mini USB socket which is arranged in a mobile device, provision is made to equip the adapter with a contact body, in addition to a micro USB plug contact or mini USB plug contact, the contact body being connected to the USB plug contact, with the contact body having at least one abutment face for resting against a surface of the mobile device, and with the contact body having at least one contact face with flat contacts. An adapter of this type renders possible a contact-making and contact-breaking process between the mobile device and, for example, a mount, it being possible for this process to be carried out virtually without any particular attention since the contact body, together with its contact faces, is designed to be mechanically substantially more robust than the sockets in the mobile device and is insensitive to contamination. Furthermore, the adapter additionally adopts the function of a protective cap for the socket of the mobile device, and therefore has a function even when the adapter is not used as an electrical component. The essence of the invention is an adapter which not only simplifies the process of making contact with a highly sensitive socket in the mobile device, but which also permanently protects the socket of the mobile device, without adversely affecting the usability of the mobile device in the process.
In one embodiment the flat contacts are in the form of strips and/or dots. This results in a smooth contact face with which contact can easily be made and on which, in particular, clothing fabrics do not get caught.
In another embodiment the contact body is formed with at least one gripping recess, and in particular two gripping recesses which are opposite one another. This makes it possible to remove the adapter from the socket of the mobile device with a fingernail, without using a tool.
In another embodiment the contact body is in the form of a covering cap which seals off the mini USB socket of the mobile device from a surrounding area. This prevents, in particular, the ingress of fluff (e.g., lint) which accumulates in the socket of the mobile device and makes the mobile device unusable. It is also possible according to the invention for the abutment face of the body to be of rubberized form or for the abutment face of the body to be covered by a flat sealing ring. This allows the socket of the mobile device to be sealed off in accordance with the provisions of IP54, which are met, for example, by outdoor mobile telephones. Therefore, an outdoor mobile telephone maintains its IP54 classification in spite of the use of the adapter.
In the arrangement according to the invention, which comprises a mobile device with a socket for making contact, a mount and an adapter, the adapter is formed from a plug contact and a contact body which is connected to the plug contact, with the contact body having at least one abutment face for resting against a surface of the mobile device, with the contact body having at least one contact face with flat contacts, and with the contact body forming a covering cap for the socket, the covering cap protecting the socket even when the mobile device is used without the mount. This makes it much easier to make contact with the mobile device in the mount, since the mount does not have to have any contact plugs which have to be inserted into the socket of the mobile device, but instead a contact strip which is arranged in the mount suffices for making contact with the contact face of the adapter. This design also makes it possible to use sprung contacts in the contact strip of the mount, and therefore a contact-connection of higher quality and with less sensitivity to vibration and manufacturing tolerances is possible. After the mobile device is removed from the mount, the adapter also serves as a protective cap for the socket of the mobile device.
The specific embodiments explained above with respect to the adapter analogously apply to the arrangement according to the invention, as well.
For the purposes of the invention, a mobile device is understood to be any electronic device which is suitable for storing and/or interchanging information. In particular, an electronic device is understood to be a mobile telephone or a personal digital assistant (PDA).
For the purposes of the invention, a mount is understood to be both a motor vehicle mount in which the mobile device is fixed in all spatial directions by a fixing means, and also a charger into which the mobile device can be inserted without being fixed.
Further details of the invention are described with reference to exemplary embodiments which are schematically illustrated in the drawing, in which:

The mobile device 17 which is removed from the mount 20 is illustrated in
The invention is not restricted to illustrated or described exemplary embodiments. Instead, it comprises developments of the invention within the scope of the patent claims.
