Definitions
- the invention relates generally to a contacting device, in particular for smart cards, and more particularly, the invention relates to a SIM block, i. a contacting device for a simcard.
- the invention aims to provide a super flat Simblock, which can be used universally preferably in a telephone, in particular in a mobile phone, where the greatest possible space savings must be achieved because of the handiness of the mobile phone.
- the super-flat Simblock should preferably be designed so that a Simcard, not only safely in one direction in the region of the contacting side, i. where the contact points of the contact elements are located, can be introduced, but preferably from a relatively large range of insertion particular Einschiebraumen.
- sim cards There are already numerous contactors for sim cards, which are often also in the form of a simblock, i. a contact carrier made of plastic in the contact elements (short: contacts) are fixed, which work together with the contact zones of a sim card.
- a Simblock usually has no cover and the pressing of the Simcard done by in the device (for example, a mobile phone) to be provided investment or support surfaces.
- US-B1-6,955,572 discloses a contactor, in particular a contact, which is arranged in an insulating housing of an electrical connector and is suitable for electrical connection to an integrated circuit, for. B. produce a processor.
- the document shows DE 100 64 137 A1 a smart card connector having a contact carrier in which contact elements are mounted, which are suitable for making contact with the contact zones of a smart card.
- the invention provides a Simblock, in which prevents the arrangement of the contact elements that during grinding operation in the longitudinal or transverse direction with respect to the Simblocks upsetting or damaging the contacts or contact elements occurs through the card and thereby a variable use of the contact block in transverse or longitudinal direction, based on the Receiveeinstory
- the contact tips of a contact element of a Simblock are then spoon-shaped, if it is necessary to be able to insert a Simcard slidably longitudinally and transversely.
- the dome edges must be within the contact body, otherwise the card may hit an edge when inserted.
- the contact tip would no longer be pressed down into the contact body, but deformed, so that the Simblock would be destroyed.
- These geometric conditions mean that the contact body height or the contact body thickness be greater than or equal to the dome height including hitch tolerances, must allow a complete immersion of the dome in the contact body. If you want to reduce the height to a minimum while creating a contact block that allows a variable mounting position in the longitudinal and transverse directions, so suitable contacts must be created in a suitable manner and housed in the contact block in a suitable manner.
- the contact elements are arranged in the direction of the bisecting line between two mutually perpendicular insertion directions, so that it is possible to insert the card without deformation of the contacts.
- the card always touches the contact arm when rubbed against the contacts and pushes them down, including the contact tip. In this way, it is ensured that the card does not first touch the tip end and deforms the contact on further insertion.
- the tip end does not have to be inside the contact body, which means that the dome height is independent of the contact body height.
- the contacts are mounted without orthogonal to the contact plane arranged mounting elements with the contact body, since the height of these mounting elements would also determine the minimum height of the contact body.

Description
Die Erfindung bezieht sich allgemein auf eine Kontaktiereinrichtung insbesondere für Smartcards und insbesondere bezieht sich die Erfindung auf einen Simblock, d.h. eine Kontaktiereinrichtung für eine Simkarte.The invention relates generally to a contacting device, in particular for smart cards, and more particularly, the invention relates to a SIM block, i. a contacting device for a simcard.
Die Erfindung bezweckt einen superflachen Simblock vorzusehen, der universell vorzugsweise in einem Telefon, insbesondere in einem Handy eingesetzt werden kann, wo wegen der Handlichkeit des Handys eine größtmögliche Platzeinsparung erreicht werden muss. Der superflache Simblock soll vorzugsweise derart ausgelegt sein, dass eine Simkarte, nicht nur sicher in eine Richtung in dem Bereich der Kontaktierungsseite, d.h. dort wo sich die Kontaktkuppen der Kontaktelemente befinden, eingeführt werden kann, sondern vorzugsweise aus einem verhältnismäßig großen Bereich von Einführ- insbesondere Einschiebrichtungen. Vorzugsweise soll es möglich sein, dass die Simkarte ohne weiteres aus einem Bereich von insbesondere 90° und mehr eingeschoben werden kann.The invention aims to provide a super flat Simblock, which can be used universally preferably in a telephone, in particular in a mobile phone, where the greatest possible space savings must be achieved because of the handiness of the mobile phone. The super-flat Simblock should preferably be designed so that a Simcard, not only safely in one direction in the region of the contacting side, i. where the contact points of the contact elements are located, can be introduced, but preferably from a relatively large range of insertion particular Einschiebrichtungen. Preferably, it should be possible that the sim card can be easily inserted from a range of in particular 90 ° and more.
Es gibt bereits zahlreiche Kontaktiereinrichtungen für Simkarten, die häufig auch in der Form eines Simblocks ausgebildet sind, d.h. einem Kontaktträger aus Kunststoff in dem Kontaktelemente (kurz: Kontakte) befestigt sind, die mit den Kontaktzonen einer Simkarte zusammenarbeiten. Ein Simblock hat üblicherweise keinen Deckel und das Andrücken der Simkarte erfolgt durch im Gerät (beispielsweise einem Handy) vorzusehende Anlage- bzw. Abstützflächen.There are already numerous contactors for sim cards, which are often also in the form of a simblock, i. a contact carrier made of plastic in the contact elements (short: contacts) are fixed, which work together with the contact zones of a sim card. A Simblock usually has no cover and the pressing of the Simcard done by in the device (for example, a mobile phone) to be provided investment or support surfaces.

Im Allgemeinen sind die Kontaktkuppen eines Kontaktelements eines Simblocks dann löffelförmig ausgebildet, wenn es erforderlich ist, eine Simkarte schleifend längs und quer einschieben zu können. Dabei müssen sich die Kuppenkanten innerhalb des Kontaktköpers befinden, da andernfalls die Karte beim Einschieben auf eine Kante treffen kann.In general, the contact tips of a contact element of a Simblock are then spoon-shaped, if it is necessary to be able to insert a Simcard slidably longitudinally and transversely. In this case, the dome edges must be within the contact body, otherwise the card may hit an edge when inserted.
Sollte dies passieren, so würde die Kontaktkuppe nicht mehr nach unten in den Kontaktkörper hineingedrückt, sondern deformiert, so dass der Simblock zerstört würde. Diese geometrischen Bedingungen führen dazu, dass die Kontaktkörperhöhe oder die Kontaktkörperdicke größer bzw. gleich der Kuppenhöhe einschließlich Kuppentoleranzen sein, muss ein vollständiges eintauchen der Kuppe in den Kontaktkörper zu ermöglichen. Will man die Bauhöhe auf ein Minimum reduzieren und gleichzeitig einen Kontaktblock schaffen, der eine variable Einbaulage in Längs- und Querrichtung ermöglicht, so müssen geeignete Kontakte in geeigneter Art geschaffen und in dem Kontaktblock in geeigneter Weise untergebracht werden.If this happens, the contact tip would no longer be pressed down into the contact body, but deformed, so that the Simblock would be destroyed. These geometric conditions mean that the contact body height or the contact body thickness be greater than or equal to the dome height including hitch tolerances, must allow a complete immersion of the dome in the contact body. If you want to reduce the height to a minimum while creating a contact block that allows a variable mounting position in the longitudinal and transverse directions, so suitable contacts must be created in a suitable manner and housed in the contact block in a suitable manner.
Erfindungsgemäß sind die Kontaktelemente in Richtung der Winkelhalbierenden zwischen zwei senkrecht zueinander verlaufenden Einschubrichtungen angeordnet, so dass es möglich ist, die Karte ohne Deformation der Kontakte einzuschieben. Durch die erfindungsgemäße Anordnung wird erreicht, dass die Karte bei schleifender Betätigung die Kontakte immer zuerst den Kontaktarm berührt und diesen einschließlich der Kontaktkuppe nach unten drückt. Auf diese Weise ist gewährleistet, dass die Karte nicht zuerst das Kuppenende berührt und bei weiterem Einschieben den Kontakt deformiert. Das bedeutet: das Kuppenende muss sich nicht innerhalb des Kontaktkörpers befinden, was zur Folge hat, dass die Kuppenhöhe unabhängig von der Kontaktkörperhöhe ist. Ferner werden erfindungsgemäß die Kontakte ohne rechtwinklig zur Kontaktebene angeordnete Montageelemente mit dem Kontaktkörper montiert, da die Höhe dieser Montageelemente ebenso die Mindesthöhe des Kontaktkörpers bestimmen würde.According to the invention, the contact elements are arranged in the direction of the bisecting line between two mutually perpendicular insertion directions, so that it is possible to insert the card without deformation of the contacts. By the arrangement according to the invention it is achieved that the card always touches the contact arm when rubbed against the contacts and pushes them down, including the contact tip. In this way, it is ensured that the card does not first touch the tip end and deforms the contact on further insertion. This means that the tip end does not have to be inside the contact body, which means that the dome height is independent of the contact body height. Furthermore, according to the invention, the contacts are mounted without orthogonal to the contact plane arranged mounting elements with the contact body, since the height of these mounting elements would also determine the minimum height of the contact body.
