Description

Description card contactor

The invention relates to a Kartenkontaktiervorrichtung, in particular a

Kartenkontaktiervorrichtung for detecting a card when inserted into the

Reader and a Vorwahnung when ejecting the card from the reader. Brief description of the prior art

Electronic card devices, or generally card contactors, such as memory card readers, are known in portable electronic devices, such as cell phones, digital cameras, and game consoles. ,

The user or user of such a device can insert different cards depending on the use in the Karteniesevorrichtung the device.

It is known in the art that some readers are provided with a switch for detecting a memory card in the reader.

Furthermore, the readers may have a second separate switch which is in front of the

Disconnect the read contacts of the card gives a prewarning signal before the card is removed from the reader or ejected from it.

Such switches serve for the effect of the so-called "hot swapping". One

Hot-swap effect is the disadvantageous effect that cards during the reading process, consciously or unconsciously from the reading position, thus removed from the reader or ejected without the reading of data from the memory card is interrupted by a switch, thus the reading process by removing or ejecting the card.

This leads to difficulties and problems and partly to data loss. In WO 2006/129170 A1, both the prior art and an alternative embodiment for preventing a hot-swapping effect are disclosed. In this respect, FIG. 1 of the description shows an exemplary output of the prior art described there.

This diagram shows a conventional system, for example in a portable electronic device. The card reader is coupled to a controller. The device itself contains a card recognition switch and a prewarning switch. The two switches are coupled to the controller for indicating the presence of a memory card in the reader and an advance warning of the removal of the memory card from the reader via the controller. The switches are electrically connected so that they are connected to the controller via separate connections.

A special design for this push-push card reader is the mechanism in which the card is inserted into its reading position at the first push and locked there and for removing the card by a second push on the card, the card from their

Reading position is removed, so briefly a little deeper into the card reader is pushed to be unlocked or unlocked from its Verrastposition and then removed from the card slot or is transported via a spring ejection out of the card slot out.

In this case, a first contact arm is used as a switching arm for a second contact with, wherein the second operable by the card switching arm contacted with its free end in the state of a non-inserted card with one end of the first contact.

When inserting a card, the second contact arm is released from the first contact arm and works in this way as a pre-warning switch.

If the card continues to be inserted, the contact end of the second arm close to the free end is brought into contact with the first contact arm at another contact point and is thus returned to a closed position.

Now it is detected that the card has arrived in its reading position or is about to reach the reading position. In this state, the reading process of the

Start inserted card. In this respect, the combined switch of a first and second reading arm functions both as a pre-warning switch and as a card presence switch.

However, this embodiment requires a card reader of the push-push type, thus a card reader, in which the card insertion and removal take place via a push. A disadvantage of this embodiment is, inter alia, the limited use of the previously described push-push card reader and on the other hand, the relatively short switching paths, which can be very sensitive to interference depending on card outer dimensions and tolerances of such cards. It is therefore an object of the present invention to provide a universally usable and inexpensive to produce card reader for different types of cards and

Karteniesevorrichtungen provide, in which, for example, SIM cards with a arranged in the center of the card contact field can be safely read in and out and at the same time the insertion of the card or the removal of the card is detected before the read contacts are moved by their mating contacts at Inserting or removing a card.

This object is achieved with a Kartenkontaktiervorrichtung according to claim 1. The Kartenkontaktiervorrichtung invention is designed so that initially a plurality of existing in at least one row reading contacts are formed with contact tips, and one of an open position to a read position back and forth operable

Card carriage for receiving a card, as well as an actuatable by means of a card Vorwarnschalter with a switching path for detecting the movement of the card slide, if a card is inserted in the card slide, wherein the Kartenkontaktiervorrichtung has a manually operable or movable card operating slide for actuating the card slide over the back card edge, so that the

Card slide is moved out of its fully inserted into the Kartenkontaktiervorrichtung reading position. The read contacts are mounted with their contact points in the Kartenkontaktiervorrichtung that the contact blades for contacting the contact pads of a card are arranged with corresponding contact fields to these read contacts. Here, the contact fields of a card to be inserted with a contact zone length L and a contact zone width B are formed. This means that when moving the card in the Kartenkontaktiervorrichtung, ie when moving the card carriage by the length L, the contact tips leave the contact zones or the contact fields of the card. As a rule, a shift by a length smaller than the contact zone length L will suffice, so that the contact tips of the read contacts are of the corresponding one

Sliding contact fields of the card, since in practice is almost never guaranteed that the contact points contact exactly on the edge along the contact zone width B, ie the outermost measure of the contact zone length L, either on one or the other side of the contact fields.

It is rather to assume that the contact points in an ideal reading position of the card contact approximately in the front third of the card or the contact fields of the card. The Kartenkontaktiervorrichtung invention is reciprocally actuated from an open position to a reading position by means of a card slide which receives the card, the card carriage has arranged on its front side in the insertion direction a handle portion to manually grab the handle section and the hand To be able to pull card slide out of the card contacting device, in particular in order to insert a card or to remove the inserted card.

The Kartenkontaktiervorrichtung further comprises an actuable Vorwarnschalter, preferably an actuatable by means of a card Vorwarnschalter with a switching path S ₃ , which is designed so that upon actuation of the card actuating slide the card slide is pushed out of the Kartenkontaktiervorrichtung only so far that the handle portion by hand comfortably is to grab, but the read contacts and the contact points of the

Read contacts still contact the corresponding contact fields.

This ensures that the so-called hot-swap effect does not occur and that the data flow is not interrupted during the read-out of data. Since the switching path S3 is selected to be smaller than the contact zone length L or approximately 60% to 70% of the contact zone length L, it is ensured in this state that there is a contact between contact tips and contact fields of the card. If the contact blades contact the contact zones in each case in the front third of the contact zones, when the card is in the intended inserted state. The front third is located to the insertion direction, ie towards the insertion opening of the card reader. The removal takes place with the card actuation slider according to the invention, which actuates the card carriage, preferably via the rear card edge.

The Kartenkontaktiervorrichtung invention is designed so that the card actuating slide can actuate the card to an actuating travel of length S1, which is smaller than the switching path S3 of the pre-warning.

The length S1 for micro SIM cards is preferably approximately 1.5 mm.

In a preferred embodiment, the condition is satisfied that the actuating travel ST is greater than the switching path S ₃ but at the same time the switching path S _{3 is} smaller than the contact zone length L of the contact fields of the card, in any case the smallest contact field of a card to be inserted.

The Kartenkontaktiervorrichtung invention is further such that the handle portion of the card actuating slide for manually pulling out of

Card carriage protruding from the Kartenkontaktiervorrichtung only when the card carriage is pushed out of its reading position by the card operating slide to the distance Si. In an advantageous embodiment of the card actuating slide with a

Warehouse equipped, where he by means of a pivot bearing in the

Kartenkontaktiervorrichtung is rotatably mounted and near the rear end of

Card slide positioned.

The card actuation slider is advantageously by means of a linear

slidable actuating slide actuated. This actuating slide is preferably along the actuating direction of

Card slide arranged laterally or parallel to the card slide and has at its end via an end-side coupling means for actuating a corresponding coupling arm of the card actuating slide.

Further, the card operating slider advantageously has a coupling arm and a card actuating arm with an end operating section for actuating the card or the card carriage, wherein the coupling arm and the card operating team are connected to each other via a bearing section.

This results in a rotatably mounted card actuating slide, wherein the end-side actuating portion in the drawer actuating direction can be actuated by the distance Si.

In other words, this means that the operating section covers an actuating path opposite to the card insertion direction K of the length when it is actuated by the user via the coupling arm of the actuating slide. Particular embodiments of the invention can be found in the subclaims.

Further advantages, objects and details of the invention will become apparent from the description of an embodiment with reference to the drawings. In the drawings: Fig. 1 is a first plan view of a card contacting device according to the invention;

Fig. 2 is a second view of the contacting device according to the invention, in which the card actuating slide was actuated by an actuating slide.

In Fig. 1 a Kartenkontaktiervorrichtung invention is shown. The

Kartenkontaktiervorrichtung has received a card 2 in their card slide 10. The card 2 has a contact pad 3 with a plurality of contact zones 4. In the present embodiment, three contact zones, in each case in a row spaced on the card 2 are arranged. The position of the contact studs 6 of the read contacts 5 is shown in FIG. 1 in the front third of the contact zone 4 of the card 2. Thus, Fig. 1 shows a state in which the card carriage 10 is fully inserted with the card 2 in the Kartenkontaktiervorrichtung. This represents the reading position of the card 2.

The card carriage 10 has a handle portion 10a at the front end which terminates in the reading position plan with the housing 40 so that it can not be manually grasped.

The card 2 has a coding 7 at its front end.

The card insertion direction is labeled K. The grip portion 10a describes the front end of the card slide 10. The

opposite rear section describes the rear end of the card slide 10. Similarly, the card can be defined. The front end of the card 2 represents the shorter end in FIG. 1, which overflows into the coding 7. The end opposite the short end of the card 2 is considered as the rear end.

The side edges lying between the front and the rear end run parallel to the card insertion direction K. Along the card slot 10 there is an actuating slide 11, which, as shown in FIG. 2, can be displaced by means of an actuator by a user or operator in the card insertion direction K. ,

At the rear end of the card carriage 10 in the Kartenkontaktiervorrichtung 1 is a card actuating slide 12. The card actuating slide 12 is rotatably mounted on a pivot bearing 13 on a bearing portion 32. At the bearing portion 32 is a coupling arm 30 and a Kartenbetätigungsarm 31 with an end

Operating section 33.

Further, a pre-warning switch 14 is disposed adjacent to the rear card end.

The pre-warning switch 14 has a spring arm 14a as a first contact and a

Counter contact 14b on. The way the spring arm 14a has to travel from this position to close the contact with the mating contact 14b corresponds to the actuating travel S ₃ of FIG

Pre-warning switch 14. This path is referred to as switching path S ₃ .

The contact zones 4 have a contact zone width B.

In Fig. 1, the prewarning switch 14 is in its open position. In this position, a card is detected in the card reader and can start or continue a read operation. To ensure that the reading process is not performed by manual removal of the

Map slide is interrupted, a switch position is provided, as this in

Fig. 2 is shown as an example. In Fig. 2 it can be seen that the contact tips 6 of the reading contacts 5 still with

Contact zones 4, although this map carriage to the distance S _! has been pushed out of the Kartenkontaktiervornchtung.

Consequently, the read operation may continue while the pre-warning switch 14 is already closed. The prewarning switch was operated by turning the card confirming slider 12 about the pivot bearing 13, i. H. an arm, namely the spring arm 14 a, are coupled to the card actuating slide 12.

The end-side operating section 33, which conveys the card or the card slide 10 out of the Kartenkontaktiervornchtung 1 and indeed by the distance S ^ Since the distance S _{1 f} has covered the map slide, in Fig. 2 is less than the switching path S ₃ of Vorwarnschalters, this is already closed and can interrupt the reading of the data in the Kartenkontaktiervornchtung 1 in this state. Therefore, the actuating slide 1 1 is formed with such a stroke that the

Card actuation slider 12 performs such a rotational movement that its end-side operating portion 13 moves the card and thus the map slide to the actuation path Si from the Kartenkontaktiervornchtung 1. Furthermore, since the condition must be satisfied that the actuation path S1 must be smaller than the length L of the map reader contact card 4, preferably less than about 60% to 70% of the length L of the contact zones, it is always ensured that a hot-swap effect can be prevented.
