Abstract
A connector (1) for an apparatus for reading smart cards (C), comprising a body supporting brush contact elements (BC1, BCX) for electrically contacting the conductive pads of a chip on a card (C) inserted into the connector. The connector comprises an electronic circuit connected to at least some of the brush contact elements (B) and connectable to the electronic circuit of the card reader. The electronic circuit on the connector comprises means for controlling the insertion of the card (C) into the card reader and its withdrawal therefrom, and one of the brush contact elements (BCX) is at a second predetermined potential and offset in relation to the other brush contact elements (BC1) so that once the card (C) has been properly inserted into the connector, one of two events occurs when the card is withdrawn and before the other brush contact elements are disengaged from the conductive pads (C1) of the card (C) that they are contacting. Specifically, either the brush contact element (BC1) at said predetermined potential and the brush contact element at a so-called earth potential are short-circuited, or said second potential varies with a magnitude no smaller than a predetermined threshold.
Description
The present invention relates to a kind of connector that is used for the microcircuit card reader device.
In the context of the present invention, " card " means all cards that a mixing or monolithic integrated optical circuit or " chip " are housed.Will be at following use term " microcircuit ".For example, they are cards of " credit card " form, also are called " memory card ".The microcircuit of card generally includes such microprocessor or microcontroller, and it comprises some memory circuits, such as " PROM " type storer.Such card is designed to insert and is used to read and/or the special device of write data.For the sake of simplicity, below these devices are called reader, even if their write datas and guarantee hereinafter mentioned other subsidiary function (supply of electrical energy, test etc.) naturally.Data storage is generally taked the form of encrypting in aforesaid memory circuit.Therefore, it is read or is written into all storage single-pieces from all storage single-pieces.
Also used other logical organization, especially for " stored value card (electronic purse) " or similar application.
All have the input-output member that is made of several contact regions under any situation, these contact regions are also referred to as " contact chip (pads) ", surperficial concordant with one of interarea (main face) of card.Various standards (ISO, AFNOR etc.) have defined the position of these contact regions.They not only are used for aforesaid data input-output, and based on related application (exist check etc.), also are used for to the microcircuit power supply and carry out various inspections.Reader comprises the brush contact that several are such, and when card was correctly inserted the connector that provides for this purpose, these brush contacts and aforementioned all zones formed and electrically contact (galvanic contact).
Currently various trend occurred, comprised:
The requirement of the security of-raising card reader device;
Therefore-miniaturization also makes the thinner trend of card reader; And
The surge that-microcircuit card is used adds falling rapidly of connector price, with the direct ratio that is expanded into of respective market;
As a result, a series of problems have to be solved simultaneously, comprise:
1. must be only when all brush contacts correctly are positioned on the contact region of card the microcircuit of card just powered on (powered up).When correctly not locating, power on, not only stop the operation of reader system, and may damage all electronic circuits of microcircuit.
2. especially, before supply voltage was imposed on microcircuit, all brushes that are used for data-signal must put in place.
3. the user can recall card (this is called as " extracting ") during handling.Therefore needing reader to arrive disabled position (promptly threatening all positions of the circuit integrity of microcircuit) at all brushes before, extremely fast reacts and cuts off power supply.
4. use any non-standard body,,,, also can cause fault no matter be unscheduled event or deliberately deceive no matter for any reason such as a current-carrying plate or pseudo-card (faked card).
Under all these situations, reader was lost efficacy, and cut off supply of electrical energy to reduce the danger that circuit damaged or cheated attempt.
Have many at some or all the reader system that reduces in these problems.They can be divided into three major types:
The first kind comprises some electronic detector system.
In this type systematic, before being added to microcircuit, carries out voltage a kind of electrical testing, for example by measuring the resistance between all brush contacts.If these tests do not produce the expectation value in the given range, then card has correctly been inserted or an incoherent object has been inserted into its position.
There are many shortcomings in this system, comprises:
All types of microcircuits operations that-this system is installed on must corresponding commercial existing various cards, corresponding at least a kind of given application (bank card etc.).Yet the kind of microcircuit is not too much so that allow single simple program.
-detect and to betide by between prohibited area and the perform region time.Obviously, under " extracting " situation, this system must react extremely apace.Suitable electronic circuit is complicated and so and expensive.
Second class comprises some so-called " landing (landing) " system.An example of this system has been described among the french patent application FR-A-2628 901.
In these systems, be able to before all brushes contact, card is located with respect to a composition surface (abutment).Form contact by card to the relative displacement of all brushes perpendicular to the surface (all interareas) of card.
Have only the proper operation of the mechanical part by system could guarantee security.Yet the latter can be supported by such " stroke end " contact (" end of travel " contact), if card is not in correct position, this " stroke end " contact lost efficacy electric sequence.Electric sequence can be set up by the height of all brushes or by initialization electronic circuit when contact (" card present " contact) " blocks and exist " to closure.
Main shortcoming is the following fact: it is complicated and expensive to finish the required mechanical layout of aforementioned all functions.
The 3rd class comprises the system with some brush contacts and " stroke end " contact.For example, such system is disclosed among the french patent application FR-A-2 623 314.
In these systems, the connector that is inserted in wherein of card provides such " stroke end " contact, its powering on of initialization microcircuit when card is in the tram.
Mechanical layout is simple and cheap.
Yet these systems are not immaculate.
In position probing, usually lack accurately, especially when all contacts are level.
If all contacts are vertical, overall dimension is bigger, and this is opposed to one of previous mentioned all requirements: miniaturization.
The applicant makes two discoveries, and is as follows:
1. before powering, only be that all " signal brush " type contact element of reader must forcibly be in the tram by " power supply brush " and " ground brush " type contact element;
2. if only for handling the insertion of the non-permission thing of conduction (for example sheet metal), then electric power system is adjusted all the time to bear short circuit.Therefore, if only be that all brushes that are constituted to the connection on supply voltage or ground are in deviation post when supply voltage is provided, then not dangerous.
Based on these discoveries, the objective of the invention is to alleviate all shortcomings of all prior art systems simultaneously for aforementioned all problems provide a solution, wherein some shortcoming is just by summary description.
For reaching this purpose, according to an important characteristic of the present invention, in the first embodiment, provide an additional contact element, with respect to all other brush contact elements in the delegation (all " signal " contact element) offset slightly, suitably forward or backward.
In second embodiment, " power supply brush " or " ground brush " type contact element are also with respect to all other brush contact elements in the delegation (all " signal " contact element) offset slightly, suitably forward or backward.
As a result, when inserting or recalling card, this skew contact element will be in " forbidding " position prior to all other contact elements.
Rely on various situations:
-or aforementioned additional contact be charged or uncharged at that time, make the supply of electrical energy that can will be instructed cut off;
-or power supply by short circuit, with its cut-out.
Under these two kinds of situations, active procedure is terminated or the starting of active procedure is prevented from.Thereby this layout prevents from a too high voltage is added to all terminals of the microcircuit of card.
Thereby, the invention reside in a kind of connector that is used as the reader device of microcircuit card, it comprises a body of supporting some brush contact elements, these brush contact elements are suitable for electrically contacting when card is inserted into this connector with the relevant all conductive region formations of described microcircuit, this connector is characterised in that it comprises an electronic circuit, this electronic circuit links to each other with some of described all brush contact elements at least, and be suitable for being connected to the electronic circuit of card reader, connector with electronic circuit comprise and be used for the device that monitors that card is inserted into card reader and recalls from card reader, and this connector is characterised in that one of described all brush contact elements of being in second specific potential are offset with respect to all other brush contact elements, make after card is correctly inserted connector one of following two kinds of situations of appearance before will block from connector all contact areas that other all brush contact element in the revocation procedure leaves the card that they contact:
-be in the described brush spare of this specific potential and be in earthy described brush spare short circuit; Or
-the specific change of described second current potential reaches the amount of a certain threshold level.
Thereby (read frame) comprises according to reading structure of the present invention: the electronic circuit described in the PCT patented claim FR 96/00156 that declared on January 30th, 1996 combines with an additional brush contact described in the EP-A-0 595 305.
In a kind of form of the present invention, this brush contact is not an additional brush contact, but such single contact element of distributing to one of described all contact areas, it is offset with respect to all brush contacts of distributing to other all contact area.

In a kind of form of the present invention, an additional contact element B
CXBackup " voltage brush " type contact element B
C1In the manufacture process of connector (referring to Fig. 5 b), this additional contact element B
CXCan on same, cut out with all standard contacts, and enter the connector body with their mold pressings simultaneously.Under this situation, it is favourable reducing the width of single diaphragm and increasing the 5th by its avris.
Additional contact element B
CXThe insertion of test card C with recall and correspondingly be connected or cut off the electricity supply, this point will be in following explanation.
It also can play the effect of " stroke end " contact element, perhaps replenishes the latter so that improve performance.
Still under card C situation according to the ISO standard, Fig. 7 a shows brush contact element B

RefThe circuit of the comparer of voltage---such as 0V---, regional M is assumed to be ground connection.In the reality, can use any reference voltage.The function of comparator circuit 3 is to detect additional contact element B
CXThe place has the potential change greater than predetermined threshold.This threshold value has been considered supply voltage tolerance, predictable interference or the like.
Suppose that also power supply 2 comprises several short circuits that is used to detect output (voltage V
CCGround connection) and output the electronic circuit that opens circuit.This operation will be performed the incident " a/ " that detects top indication: the detection of short circuit.
Incident: " b/ " (additional brush contact element B

Fig. 7 c is display card C also
ArdThe situation of recalling, but in this example, do not have ground area M (Fig. 7 a and 7b).C is removed (arrow F from connector when card
R) time, the current potential C at additional contact element place

Fig. 9 a shows employed structure under the situation of the card C meet the AFNOR standard.The composition surface (not shown) is positioned at zone C
1A relative side.For the purpose of more accurate, this figure shows normal operating conditions.Additional contact element C
BXTo contact element C
B1The place ahead skew but rest on the zone C 1.Therefore, C
BXAnd C
B1Two contact elements are in identical current potential.Also suppose by zone C
5The ground area and the zone C that form
1Adjacent.
When card C is withdrawn, such as being to extract, shown in Fig. 9 b, ground area C
5To additional contact element C
BXMove.
As aforesaid, can detect two kinds of different incidents:
A/ ground area C
5With voltage regime C
1Between short circuit, this is because additional contact element B of a certain moment
CXStay on these two zones;
B/ adds contact element B
CXThe variation of place's current potential, it is by value V
CC(such as+5V) change to 0V.
In the reality, change in voltage gets final product greater than a given threshold value under a kind of situation in back.Therefore, needn't wait for that voltage reduces to 0.
And, as the aforementioned, all other contact element B
C2To B
C8Have little time to leave respectively zone C
2To C
8
As the aforementioned, these two kinds of incidents can be handled by all electronic circuits that use Fig. 8.
At last, shown in Fig. 9 c, if zone C
1Near do not have the ground area, then only have incident " b/ " to take place and can detect by identical circuit (more accurately can by comparer 3).
The embodiment of just having described has reached all purposes of setting for the present invention fully.
Yet, as pointed, two kinds independently state or incident must be detectable, this need have the additional contact element B of control in reader
CXElectronic circuit.ｘ
In the second embodiment (not shown) of the present invention,---all " power source brush "---is offset a little with all other contact elements in the delegation relatively with " voltage brush " type contact element.Under this situation, do not need additional contact element B
CXTherefore, this embodiment is more simple.
Under the situation of according to the ISO standard card, with respect to all other contact elements---" signal brush ", with " voltage brush " type contact element B
C1Skew gets final product to the composition surface.If " power supply " zone C on the composition surface
1No longer than all " signal " zone, then this skew is enough to guarantee correct order.
Yet aforementioned iso standard does not guarantee to satisfy this requirement, and in fact many bank cards have inappropriate " power supply " regional structure.
Therefore, this embodiment is retained to all application-specific.
Under the situation of the card that meets the AFNOR standard, with respect to " signal brush " type contact element, with " voltage brush " type contact element B
C1Be offset on one side on the composition surface.Referring to Fig. 9 a to Fig. 9 c, use contact element B once more
C1Replace additional contact element B
CX
This may guarantee in proper order correct after power supply is by short circuit by cutting off the electricity supply.
Naturally, the major advantage of second embodiment is that the state that is not required to be all brushes provides any control electronic circuit.Further, only need contact element B
C1Revise slightly.
Yet as what mentioned, some card is incompatible, and reason is zone C
1Shape, this shape can not guarantee to satisfy all standards.
Naturally, effective for making the present invention, must satisfy multiple demand.C is in position, composition surface and standard contact elements B when card
C1With additional contact element B
CXBetween exist when departing from (first embodiment), these demands relate generally to and meet fabrication tolerance and contact element B in connector
C1With respect to zone C
1Positional tolerance.
For making this example more concrete, the distance of the centre distance card composition surface b of zone C 1 equals 18.87mm, and tolerance is maximum+0.4mm minimum-0.5mm.As what mentioned, be parallel to F
RZone C on the direction
1Width be minimum 2mm and C
1With one in abutting connection with C
1The zone between distance be 0.2mm.
Must be compatible with the manufacturing accuracy that obtains with these values.This requirement not only relates to all contact elements itself and their relative position, and relates to other operation, such as molded or the like.
Yet all these operations are results of some process choice of understanding of skilled person.
Read above explanation and clearly illustrate that the present invention has many advantages, comprise following pointed all advantages.
When relating to precision, in the prior art connector that provides " stroke end " type contact element, the assurance of correct order is depended on:
The mechanical precision of-aforesaid all contact elements;
-Zhu contact area is the position at the edge of card relatively;
The position of-Zhu brush contact element all relatively " stroke end " type contact element;
Under the situation according to connector of the present invention, precision depends on:
The skew of-desired all brush contact elements, this is by cutting and the processing of crooked all brushes acquisition;
The precision of the size of-Ka and all contact area spacings, this is by cutting or roughly the same process generation;
The overall accuracy that is obtained only is better than the precision that obtained under some " stroke end " type contact element is auxiliary.
Overall dimension can be less than the overall dimension of roughly the same all prior art connectors, and this is that this can allow to reduce thickness because can save all " stroke end " type contact element.
On the contrary, if keep all " stroke end " type contact element, all measures then of the present invention improve reliability because of crowding effect.
At last, if all " stroke end " type contact element is removed then can reduces cost, even if also like this in the first embodiment, this is because additional diaphragm is only introduced additional processing charges.
