- manipulation protection according to the invention can be applied in many ways, the manipulation and puncture protection should be described in particular for a magnetic head recording with magnetic head.
- a hybrid reader 10 which has a housing 11, are arranged in the contact elements for contacting a chip card.
- a connection flexprint 13 is connected to the contact elements of the smart card connector provided by the hybrid reader.
- a magnetic head receptacle 15 with an inserted magnetic head 16 (not visible in FIG. 1) is provided on a housing 1 1 forming an insertion slot 12 for a chip card or a smart card, so that the hybrid reader 10 is formed.
- the magnetic head receptacle 15 is fixed by means of a screw 18 to the housing 11, and is guided with its guide lug 17 between two webs which are fixed on the housing 11.
- the magnetic head receptacle 15 has an elongated plate 19, which has a bottom 21 and an upper side 22 (with respect to FIG. 1).
- a magnetic head receiving portion 23 is formed at one end opposite to a fixing end of the plate 19.
- the magnetic head receiving portion (FIG. 11) has four walls 24 to 27 defining a recess 28.
- a housing 30 having magnetic head 16 is inserted into this recess 28 with a top 31 in front and is held therein.
- the magnetic head 16 may be held in the recess 28 by gluing.
- the magnetic head 16 and its housing 30 opposite to its upper side 31, a bottom 32, which comes into contact with the magnetic strip of the magnetic card.
- the magnetic head housing 30 has four preferably perpendicular to each other side walls 33 to 36, wherein the housing 30 is substantially cuboid.
- (insulating) feet 37 to 40 protrude upward in each of the corners.
- solder pad 47 serving as a ground terminal contact is provided on a side edge of the side wall 35, between filling elements 48, 49 disposed on its upper side 31 on both sides thereof, for preventing penetration of a drill on this side of the Magnetic head 16 serve where the Schutzflexprint 14 is led out of the magnetic head 16.
- the above-mentioned fastening screw 18 extends through a hole 67 in the protective flexprint 14 and further through a hole 20 in the elongate plate 19 and is screwed into the housing 11 so as to fix the magnetic head receptacle 15 on the housing 11.
- the protective flexprint 14 generally has the structure of a known flexprint, but has a special construction which provides manipulation security for the magnetic head 16 and also for the protective flexprint itself, resulting in the term "protective flexprint.”
- the protective flexprint 14 has, for example, FIG , a magnetic head connection region or inner region 80, and then an intermediate region 81, which is followed by a device connection region 82 at the other end of the protective flexprint 82, contact surfaces or contact zones 83 are formed (on a data transfer layer 62 to be described later) 12. Twelve contact zones 83 are provided in the exemplary embodiment shown, and the protective flexprint 14 is preferably constructed with five layers in the outer region of the magnetic head receptacle 15 s will be explained in detail.
- the centrally located data transfer layer 62 is used, in particular, to transfer data between the magnetic head 16 and a device (not shown).
- Each outer layers 60, 61 serve as protective layers and are in detail as a first or upper protective layer 60 and second or lower protective layer
- the protective flexprint 14 in the outer region 81, 82 is preferably of a five-ply design
- the protective flexprint 14 is constructed in the interior region, ie in the contact area between the magnetic head 16 and the protective flexprint 14, preferably in three layers.
- the data transfer layer 62 to the top 31 of the magnetic head 16 and the first or upper protective layer 60 faces outward.
- the Structure of the first protective layer 60 and the second protective layer 61 is preferably identical.
- the structure is provided such that in the protective layers 60, 61 conductor tracks run in such a way that when the protective layer 60 or 61 is drilled or pierced, it is sufficient for a conductor or a conductor track to be severed in the one protective layer, or Connection of two tracks is produced in a protective layer, which can be determined as a corresponding change in the resistance behavior at certain of the contact zones 83, which are connected to the corresponding conductors in the protective layers.
- the three-layer structure of the protective zigzag 14 changes to a two-layer structure in the magnetic head connection region 80.
- the protective flexprint 14 is connected (or soldered) to the magnetic head 16 or its contacts, preferably by an electrically conductive adhesive. This happens in such a way that the line 87 where the second or lower protective layer 61 ends already falls in the region protected by the magnetic head 16 itself, in particular by its filling elements 48, 49 and the ground contact or ground connection 47.
- the data transfer layer 62 continues to be located in the inner region 80 and forms the contact surfaces 91 to 96 which serve for contacting the connection contacts 41-47 and the ground contact 47.
- the upper protective layer 60 continues, in the case of FIG. 9 in the flap 71 running around the side wall 33 of the magnetic head 16 knocked around and attached to it.
- the upper protective layer 60 further forms the flaps 70 and 72, the protective layer 60 of course is formed such that the necessary interconnects run inside to make a piercing or drilling of these flaps 71-72 detectable.
- FIG. 2 and more clearly in FIG.
- the flaps 71-72 preferably sit in recesses 74 formed by the side walls 24, 25 and 26, so that additional protection is achieved (FIG. the recess 74 is easy to see only for the side wall 24). Also formed by the side wall 27, the side wall 27 by cutting through recess 29, acts protectively and allows the introduction of Schutzflexprints 14 in the read head sixteenth
- the tamper protection is realized via two parallel separate lines located at different potential.
- the lines are laid, for example, in a width of 0.2 mm and at a distance of 0.2 mm from each other in a sheet-like insulating material.
- the lines thereby form a continuous loop, which preferably extends over the upper protective layer 60 and the lower protective layer 61. There is always a conductor loop between the located at a potential separate conductor loop.
- the printed conductors laid in the protective layers are connected at the corresponding points to printed conductors in the data transfer layer 62, which are preferably not only for data transfer but also for connection to the printed conductors in the protective layers 60, 61 serves.
