Description

The invention relates to a connection device for contacting conductors of a continuous flat cable having a plurality of conductors, which are optionally each surrounded by insulation and embedded in a parent cable sheath, with a multi-part base housing, which is designed for supporting the flat cable, wherein on the Base housing a plurality of insulation piercing contacts, in particular fork contacts or Piercingkontakte, arranged for contacting a plurality of the conductors of the flat cable.

Such connection devices with insulation-penetrating contacts are known per se. They are used for fast and reliable wiring of flat cables with relatively many conductors.

From the DE 34 22 607 C1 It is known to form the connection device such that it can be placed only on the flat cable when a conductor or a wire has been previously interrupted at the Aufsetzstelle and has a breakthrough in this area. In the interrupted area of this wire approaches engage on one of the parts of the connection device. This serves to position the connection device and ensures that can only be mounted if corresponding openings are provided. In addition, the approach separates and isolates the two ends of the interrupted conductor. This solution has proven itself, especially when used in confined building shafts, as it is easy to handle. An analog solution shows the EP 1 518 812 B1 , which a connection device according to the type DE 34 22 607 C2 intended for use in lift shafts, where, for example, the safety circuit is to be interrupted in each case.

The EP 1 936 747 A2 discloses a generic connection device. Whose base housing is constructed in several parts and has a base portion and a cover portion, which in turn are configured in several parts. Preferably, a sliding cover is provided which is guided displaceably on a base plate and having on its inside wedges, which cooperate with wedges of a support plate, wherein the support plate with the cable and a receiving plate for the cable as a unit pressed together on the insulation piercing contacts becomes. This version is compact and still realizes a particularly safe wiring.

Although the structure of the generic EP 1 936 747 A 21 proven in itself. However, there is still the need to further develop the generic connection device, in particular with regard to an even easier contactability.

The solution to this problem is the object of the invention.

The invention solves this problem by the subject matter of claim 1. Thereafter, on the base housing at least one eccentric unit can be arranged (or arranged when contacting), with which the flat cable can be pressed on the insulation piercing contacts until one or more of its conductors are contacted. The contacting of the flat cable is so simple and easy.

Particularly preferably, the eccentric on an eccentric housing, into which an eccentric roller is inserted, which is rotatably mounted in the eccentric housing and which is supported against abutment-like in a wiring in or on the base housing against a Beschaltungsrichtung, wherein upon rotation of the eccentric roller, the eccentric housing moved relative to the base housing, so that the flat cable with the eccentric unit can be pressed onto the insulation piercing contacts until it is contacted. The eccentric unit formed in this way has very compact dimensions and still allows a simpler and more secure contacting of the conductors of the flat cable with the insulation-piercing contacts.

The invention also provides the training - and according to a variant and independent invention - the claim 28th

Thus, claim 22 provides a connection device according to one of the preceding claims or according to the preamble of claim 1, wherein the contact plate unit is formed as a printed circuit board unit which has at least one printed circuit board which is placed on the base plate, at least in the region of the insulation-penetrating contacts on the Circuit board is placed a protective plate having openings, in particular slots, which at least partially pass through the protective plate, and from which protrude the insulation piercing contacts, wherein the protective plate recesses for receiving and supporting base portions the insulation piercing contacts when contacting the insulation piercing contacts, which are conductively connected to the circuit board. In this way, it is possible in a simple manner to support the relatively large forces which occur when contacting the insulation-penetrating contacts over a larger area on the printed circuit board or even on a component under the printed circuit board in order to protect the printed circuit board.

It is advantageous if offset to a housing in the main direction of extension of the flat cable and two or more eccentric units are movably guided, in particular are displaceable in order to contact the flat cable in its longitudinal direction at different locations. It is advantageous if the housing of these connection devices can be connected to positive locking means (and / or adhesion means), for example to corresponding geometries of one or more dovetail connections.

According to the characteristic of claim 23, a punching device for severing one or more conductors of the flat cable is attached to the connecting device in the main extension device of the flat cable. Since the punching device is not integrated into the housing of the connecting device but is formed separately therefrom, it is possible to provide it selectively only in cases in which a severing of the conductor, e.g. For the realization of a safety circuit is absolutely necessary. It is particularly advantageous if the connecting device and the punching device corresponding positive locking means - one or more. corresponding, one another plug-in grooves and pins - have, at which they can be arranged in the main extension direction.

It is advantageous and preferable, because practical and constructive compact and simple, if the connection device and the punching device have corresponding positive locking means, to which they can be arranged in the main extension direction and / or that in and against the Hauterstreckungsrichtung to the housings of the connecting device and / or the Punching device one or more. corresponding grooves and pins are formed, which together form a kind of dovetail joint.

It is also expedient and thus advantageous if the punching device has a housing with a housing lower part and an upper housing part, wherein preferably the upper housing part has one or more openings which are aligned perpendicular to the flat cable and radially aligned with this, and that in the respective opening respectively at least one punch can be used, with which a lying below the opening conductor of the flat cable is severed, wherein preferably the lower housing part is designed for placing the flat cable and that the upper housing part on the lower housing part attachable, in particular can be latched

Fig. 1 shows a perspective view and Fig. 2 an explosive view of a first embodiment of a connection device 1. A further embodiment is in Fig. 8a - c shown. The connection devices 1 are for contacting a flat cable 50 (see also Fig. 5 and 8a ), which generally has a plurality of conductors 51, which are preferably each surrounded by an insulation 52 and embedded in a parent cable sheath 53.

The flat cable 50 has a main extension direction X and extends flat in the X / Y plane. It is contacted by the contacting device in a direction -Z. The X / Y plane is in the exemplary application of the Fig. 1 aligned horizontally. The direction Z is then the vertical direction. The following terms used as above, below, right, left, etc. are in the installed position of Fig. 1 to relate, in which the connecting device is placed on a horizontal support, not shown, oriented. They change accordingly in a different mounting position on a vertical wall or the like. And are therefore beyond the installation position not restrictive to understand.

The connection device 1 is used in particular for contacting flat cables in building shafts, for example in lift shafts. It has a one- or multi-part base housing 2 ( Fig. 3 . 8a ), which has a base portion 3 and a cover portion 4. The base section 3 is in a preferred embodiment as Base plate 3 formed with a substantially rectangular shape. The base plate 3 may have - for example in the region of one or more of its corners - attachment areas 5, to which it can be attached to a base such as a wall. For this purpose, the attachment regions 5 can have attachment openings, for example, to which the base plate 2 can be fastened to the base with fastening means (not shown here) such as screws. The cover portion 4 may be fixed to the base portion 3, for example, latching or otherwise. To Fig. 8a-c These sections 3 and 4 are integrally formed or connected.

The base plate 3 extends parallel to the plane of the flat cable 50 to be contacted. Here, it also has lateral webs 6, which project from the plane of the base plate 3 parallel to one another at the upper side remote from the lower fastening side.

On the base plate 3, a contact plate unit is placed or placed ( Fig. 1 . 2 ). This contact plate unit is after Fig. 1 . 2 and 6 formed according to a first type as a printed circuit board unit 7. The printed circuit board unit 7 has at least one printed circuit board 8 which can be placed directly on the base plate 2 or is designed. On the circuit board 8, a plurality of insulation piercing contacts 9 (also called insulation piercing contacts) arranged (preferably soldered to this), which preferably protrude perpendicularly from the circuit board 8 upwards. Here, the insulation piercing contacts 9 each form a contact fork with cutting edges, which taper towards their free ends. Each of the contact forks is designed to cut through the insulation of a conductor and to contact the thus exposed conductor contacting this.

In the region of the insulation-penetrating contacts 9, a protective plate 11 is applied to the printed circuit board 8, which has a smaller area than the printed circuit board 8. This protective plate 11 has openings, in particular slots 12, which at least partially pass through the protective plate 11. As in the exemplary populated printed circuit board assembly of Fig. 6 can be seen, the insulation-penetrating contacts 9 in the openings 12 are preferably supported advantageously downwards, so that the protective plate 11 forms an abutment in the contacting. The actual contacting of the circuit board 8 takes place laterally of the support areas and preferably laterally of the slots 12 of the protective plate 11 (not visible here).

The protective plate 11 serves to support and stabilize the insulation-penetrating contacts 9 and to protect the (in Fig. 6 not shown) printed circuit board 8 when pressing the flat cable into the conductor 51. The preferred embodiment of the embodiment of the insulation piercing contacts will be further below with reference to Fig. 10 and 11 described.

Furthermore, one or more connection contacts such as socket or pin strips 13, 14 can be arranged on the printed circuit board 8, to which conductor ends or plugs or the like of an electrical / electronic assembly, not shown here, can be connected. In any case, the connection direction Y / Y of these sockets and / or pin strips 13, 14 is in some cases oriented perpendicular to the main extension direction X of the ribbon cable. They may also be wholly or partially aligned in the direction of arrangement or main extension direction of the flat cable. In this case could be realized by corresponding pin / knife and socket contacts, preferably a direct conductive connection between juxtaposed connection devices (not shown here). The female and male headers or other connections are preferably accessible from the outside between the base plate 3 and the cover section 4.

On the base portion 3 with the circuit board unit 7 of the cover 4 is placed or placed ( Fig. 1 ). The cover section 4 has a lower frame section 15, from which two webs 16, 17 extend vertically upwards. In a view in the YZ plane, the cover section 4 thus substantially has a U-shape (FIG. Fig. 2 ).

In the area between the parallel webs 16, 17 a rectangular receiving space is formed here, in which a cable support plate 18 can be inserted. The cable support plate 18 serves to support the actual flat cable 50. It may have mutually parallel grooves 19 so that it adapts well to a correspondingly shaped flat cable 50, so that its conductors are defined parallel to each other on the cable support plate 18. The cable support plate 18 also has openings passing through it, in particular slots 20, which in turn are penetrated in the contacted state by the free ends of the insulation-penetrating contacts 9.

The cable support plate 18 can perpendicular to the plane of the flat cable 50 slidably but parallel to the plane (X- / Y-plane) immovably on Führungsausnehmungen 21 of the webs 16, 17 of the cover 4 to be performed. It can also be attached to two or more sides, in particular on three sides - catch 55 ( Fig. 2 . Fig. 8a ) or the like, with which the cable support plate 18 in (not to be recognized in detail here) contours (see, for example, the edge 66) of the housing 4 is latched. This is preferably done in such a way that a certain displaceability of the cable support plate 18 is maintained in the Z direction relative to the housing 2.

The cable support plate 18 may also be resiliently supported with one or more springs 54 on the frame portion 15 of the cover 4 of the housing 2. Here, these springs 54 are formed in a preferred embodiment as coil springs. A use of differently designed springs is conceivable. The springs may also be formed as one or more resilient portions on the housing 2 and / or the cable support plate 18 (not shown here). It is advantageous that a bias of the cable support plate 18 against the contacting direction (-Z) is achieved by the springs, which helps to ensure a precise contacting process.

The webs 16, 17 have a kind of triangular shape in a view from the X / Z plane and are so far from the frame portion 15 in the Z direction that they arranging, moving and storing at least one or more (the latter not here shown) eccentric unit (s) 22 allow.

Two different types of eccentric units are considered below ( Fig. 4 . Fig. 7 ). Each eccentric unit 22 has a substantially cylindrical eccentric roller 23, which has on its axial sides lateral bearing journals 24 of smaller diameter, which serve to support the eccentric roller 23.

The bearing pins 24 are arranged eccentrically to an imaginary center axis M of the eccentric roller. The eccentric roller 23 preferably has on its outer circumference at least one flattened region 25 (see Fig. 8a-e ). The eccentric roller 23 is further provided with a radially extending slot 26 which extends from the outer diameter preferably through the central axis M a piece in the eccentric roller 23 inside. The slot 26 serves as a neck contour for an actuating tool, here a screwdriver.

The eccentric roller 23 is - inserted here from the side in a one- or multi-part eccentric housing 27 of the eccentric unit 22 and rotatably mounted in this. The eccentric housing 27 here has a rectangular shape in the X / Y plane. It is designed to fit into the frame section 15 (in its opening 28, see FIG Fig. 2 ) of the cover section 4.

The eccentric housing 27 surrounds the eccentric roller 23 according to the first type of Fig. 4 almost complete. But it preferably has on its side facing away from the base portion a window 31 which is formed so that the actuating tool in the approach contour (here the slot 26) can be inserted and that the eccentric roller 23 can be pivoted so far as it is for a Wiring is necessary.

The eccentric housing 27 further has a section, in particular a (or two mutually parallel) side wall 29, in which a senkreckt (in the Z direction) extending slot 30 (FIG. Fig. 4 ) or a slot 30a is formed. The slot or the slot are penetrated by the bearing pin 24 of the eccentric roller 23.

The eccentric roller 23 is rotatably mounted in the eccentric housing 27. The eccentric housing 27 has a pressure side 27a in the direction of the insulation-penetrating contacts 29.

The width of the eccentric housing 27 (the distance of the side walls 29) in the Y direction corresponds to the distance Y1 (see Fig. 3 ) between the webs 16, 17 of the cover 4. In the webs 16, 17 of the cover 4 each have a receiving contour 32 is further formed, which allows insertion of the bearing pin 24 of the eccentric unit 22. Preferably, the receiving contour 32 is formed such that the eccentric housing 27 can be inserted with a movement component in the X direction until it comes to a stop 33 in the X direction to the plant, which is easy to feel when inserting the eccentric 22.

Preferably, each receiving contour 32 of the cover 4 also has upwardly in the direction away from the base plate direction advantageously a vertical abutment 34, which is preferably (for example in the manner of a semi-cylindrical space) rounded and against the contacting direction -Y a stop in the manner of a Abutment and seat for the journals 24 forms. The bearing pin 24 of the eccentric shaft 23 may also be formed as ends of a continuous shaft (not shown here).

At its in the mounted state on the cover section 4 of the housing 2 to the flat cable 50 facing lower side, the plunger 27a of the eccentric housing 27 of the eccentric unit 22 each at least in one or more areas one or more projections 35 as an abutment to the contacts on the pressure side 27a, in which the flat cable is to be pressed onto the insulation piercing contacts 9 and in which it is cut by these. In this way, it is advantageously possible to apply the wiring force in a more targeted or relatively "punctiform" manner into the region of the flat cable 50 in which it is to be contacted ( Fig. 8a ).

The function of the connecting device with eccentric unit 22 described above with respect to its construction when contacting a flat cable is as follows.

The housing 2 of the connecting device 1 is pre-assembled to the eccentric unit 22 (see Fig. 3 ), placed on a mounting base and this preferably firmly mounted (for example, it is screwed to the mounting base, not shown here).

Now the flat cable 50 is placed on the pressed by the springs 54 cable support plate 18 between the webs 16 and 17. Then, the eccentric unit 22 is guided with a movement component parallel to the flat cable in the space between the webs 16 and 17, so that the bearing pin 24 engage in the receiving contour 32. The eccentric unit 22 is moved as far as the stop 33 of the receiving contours 32. The journals 24 are - unlike in Fig. 1 shown in the oblong holes 30 (or in the slots 30a, see Fig. 9b ) in the lower position. Then, the eccentric roller 23 is rotated from the outside with an actuating tool (compare the positions of the slot 26 in the Fig. 8a, 8b . 8c ). Thus, on the inside of the lower side or wall 27a of the eccentric housing 27 inside a compressive force in the direction of switching (- Z) is exerted, which moves the eccentric housing 27 with the pressure side or wall 27a and their projections 35 in the direction of the insulation-penetrating contacts 9 ,

Further pivoting of the eccentric roller 23 presses, since the bearing journals 24 in the cover section 4 in the Z direction are supported and fixed in the abutment manner at the contour 34, the pressure side 27a continues perpendicular to the flat cable 50 in its direction (direction -Z, Fig. 8b ). As soon as the lower side 27a (here with the projections 35) reaches the flat cable 50, the flat cable 50 is pressed onto the free ends of the insulation-penetrating contacts.

The pivoting is continued until the flat cable 50 is pressed onto the insulation-penetrating contacts 9 so far that they pass through the cable sheath 53 and the insulations 52 and contact the one or more conductors 51 to be contacted securely (FIG. Fig. 8c . 9c ). This position is here advantageous to reach the flattened portion 25 of the eccentric roller 23, which increases the security when wiring ( Fig. 9c ). The wiring thus requires only relatively small forces and is easy and easy to carry out manually. The flattened area also ensures a defined position in the manner of a "rattle" and thus prevents rotation of the eccentric roller.

In the first embodiment of the eccentric unit 22 of the Fig. 4a ) to e) latching in a first position before contacting and after wiring or contacting in the simplest way by a small projection 67 is reached here in both positions before and after contacting each detent in a small opening 68, 69th engages in the side wall 30 of the eccentric housing 27 with the slot 30 ( 4 b) to d) , This facilitates the contacting process and keeps the eccentric roller 23 in the respective position reached.

In the second embodiment of the eccentric unit 22 according to Fig. 7 the eccentric housing 27 is open at another, in particular the upper, side, so that the eccentric roller 23 can be inserted into the eccentric housing 27 from this side. The eccentric housing 27 then has the two upwardly open slots 30a, which are traversed by the bearing pin 24 after insertion of the eccentric roller. At the bottom, one or both slots may have a taper 36 (FIG. Fig. 9b ), so that the bearing pins 24 can be latched in the slots 30a in a lower mounting position, from which they are moved into the contacting position.

The preassembled eccentric housing 27 is just as used for contacting the flat cable 50 as the previously described eccentric housing. If the eccentric roller 23 is pivoted, its outer circumference again presses against the housing wall 27a lying in the direction of the insulation-penetrating contacts, which is advanced in the direction of the insulation-penetrating contacts 9 until the flat cable is pushed down on the insulation-penetrating contacts 9 so that they contact the contacting conductors securely ,

The insulation piercing contacts 9 may, but need not be, mounted on a circuit board unit 7. They can also be preassembled on another contact plate unit.

The mounting base may, for example, as a contact plate 8 '(see Fig. 8a ), in which blind-hole-like bores or slots or stepped bores or slots 37 are configured, so that the contacts with base sections 40 are arranged and supported in the contact-receiving plate 8 '. These base sections 40 may also be part of conductor connections.

After the variant of the connecting device of Fig. 1 to 6 the contact-receiving plate is designed as a printed circuit board. According to another variant of the connecting device of Fig. 8a By contrast, the contact-receiving plate is not a printed circuit board, but is provided with terminal contacts 72 for connecting conductor ends 75 or the like, which are conductively connected to the insulation-piercing contacts 9. The connection contacts 72 are preferably accessible from the rear side of the housing 2 ( Fig. 8b . c ). To Fig. 8 the base portion 2 and the cover portion 4 are integrally formed, that is, that the housing 2 is in one piece, which is possible due to the still to be discussed other design of the contact-receiving plate. The actual contacting of the flat cable but designed according to the variants of Fig. 7 and 8th analog or even the same as after Fig. 1 to 6 ..

To Fig. 8a ) to e) and f), the contact-receiving plate 8 is preferably also provided with openings 68 in the region of the slots or openings 37 from the opposite side. In one of the openings 68 conductors are inserted. Here is another of the openings 68 formed for insertion of an actuating tool. The openings 68 open into contact chambers 71 for connection contacts 72 for conductor ends 75 of conductors 76 or the like. Arranged ( Fig. 8c ). The contact chambers 71 are formed by the openings 37. In the contact chambers 71, the insulation piercing contacts 9 are supported in the wiring. These connection contacts 72 can be designed as spring contacts or screw contacts or the like. In the present case, they are designed as compression spring contacts in direct plug-in technology (push-in). The openings 68 are preferably accessible from the rear of the housing (they Fig. 8a ), b) and c). In this case, connections on the sides (strips 13, 14) are not required. The conductors are preferably led out through recesses or openings 74 in the housing 2 ( Fig. 8a, b . c ).

In the direction of the eccentric unit 22 may be a cover plate 38 (here with locking webs 73) placed on the contact receiving plate / surface 8 ', which itself has smaller openings, in particular slots 39, as the contact receiving plate 8', from which the free ends of the insulation piercing contacts with the cutting edges projecting outward in the direction of the eccentric unit 22. Also, the insulation piercing contacts 9 are securely guided and held. Of the base portions 40 of the insulation piercing contacts 9, a conductive connection preferably extends to at least one of the external conductor or plug connections 13, 14.

If a printed circuit board arrangement 7 with a printed circuit board 8 (FIG. Fig. 1 to 6 ), the following arrangement of the insulation-penetrating contacts 9 on the printed circuit board assembly 7 is particularly advantageous. Each insulation piercing contact 9 has the actual contact cutting edges, to which at the side remote from the tips of the insulation piercing contacts side again a base portion 41 connects, which is inserted into openings 12 in the protective plate 11 on the circuit board 7. If a force is exerted on the free end of the insulation piercing contact 9, this is so securely supported on the protective plate 11 as an abutment. In this way, the forces exerted selectively on the insulation penetrating contacts 9 can be distributed over the protective plate 11 either in a distributed manner in the printed circuit board 8, which protects them in a simple manner from too high a load, possibly leading to destruction ( Fig. 10 ). Alternatively, it is also possible, the protective plate 11 by means of webs 42, which pass through the circuit board 8 at the base portion 3 of To support the housing ( Fig. 11 ), so that the circuit board 8 almost completely free of wiring forces.

The actual contacting of the printed circuit board 8 via a conductive connection, such as a busbar piece 43, which is aligned at an angle, in particular at right angles to the Beschaltungsrichtung - at the base portion 41 and preferably via an angle to the busbar piece 43 aligned pin portion 65 which passes through the protective plate 11 and soldered on or in the circuit board 8. Preferably, this "location of the soldering" perpendicular to the Beschaltungsrichtung (-Z) to the cutting edges of the insulation piercing contacts 9 spaced. The busbar piece 43 may also be designed U-shaped and then pass into the pin section 65. The U-shaped busbar piece 43 can thus easily spring in the Z direction.

It is also advantageous to line up several of the connection devices in the main extension direction of the flat cable. For this purpose, it is preferred that on the mutually facing sides of the housing 2 of the two connecting devices 1 to be connected to one another corresponding positive locking means are formed, so that the connecting devices 1 are held together in a form-fitting manner. For example, in the main direction of extension of the housings, in particular on the webs, one or more. corresponding grooves 44 and pins 45 (see, eg Fig. 1 ) formed, which together form a kind of dovetail joint.

As described above, in some applications, it is necessary to contact one or more of the conductors of the flat cable 50 offset in the main extension direction at two locations. In this case, it is also often necessary to interrupt the conductor between the two locations where the conductors of the flat cable are contacted. This can be done with a pair of pliers or the like, with which a hole is punched in the head. But it is easier to use the following arrangement (see Fig. 12 to 14 ).

For spaced contacting of the flat cable 50 two offset in the main extension direction X of the flat cable arranged contacting devices are arranged on the flat cable.

According to a development, which is also to be regarded as a separate invention and, for. is also used in another Beschaltungsart for the IDC contacts 9 as a Exzenterbetätigung is set to one or between two of the contacting devices 1, 1, a punching device 46 with a housing 47 and a punching means for punching one or more conductors.

On the housing 47 of the punching device 46 positive locking means are formed, in particular pins 44 and grooves 45, which correspond to the positive locking means of the housing 2 of the connecting devices. In this way, the housing 46 can form-fit between the housing 2. 2 of the two connecting devices 1; 1 are set. This type of arrangement is simple and advantageous.

The housing 47 of the punching device 46 has a housing lower part 48 (FIG. Fig. 14c ) and an upper housing part 49 ( Fig. 14a, b ). The lower housing part 48 preferably has a U-shape in an XZ view. The lower housing part 48 allows the laying of the flat cable 50, which is held between two Z-directional webs 57, 58 inserted and centered. A support region 59 of the housing lower part has depressions 60 below regions in which the flat cable is to be severed.

The upper housing part has one or more openings 61, which are aligned perpendicular to the flat cable and aligned with this radially. The openings 61 lie in the Z direction above the depressions. If a punch 62 is driven into the respective opening 61 as a punching means, for example punched into the opening 61, the conductor 51 located below the opening 61 is severed. This type of interruption of the circuit is easy and safe to carry out. Since the punching devices is a structurally separate unit from the connecting devices, it must be used only in this application and can otherwise be saved. The upper housing part 49 may be fastened to the lower housing part 48, for example with latching means. By way of example, these comprise two preferably releasable latching hooks 63, which are designed for latching to corresponding latching contours 64 of the housing lower part 48. In this way, the conductors of the flat cable can be interrupted easily and yet precisely. The handling is advantageously simple and yet leads to very precise results. The openings could also initially be closed and in the manner of a prefabrication by breaking out eg be opened by molded surveys. The fitter then knows exactly where he has to punch each punch at the job site.

Fig. 15 shows in a) to e) a third variant of a connection device 1 for contacting flat cables, which may be laid in particular in shafts, preferably in lift shafts. In turn, it shows the here two-part base housing 2 ( Fig. 3 . 8a ), which has a base portion 3 and a cover portion 4, which are integrally connected or latched or otherwise connected. There is also a kind Bodenabdeckplatte 3 'is provided, which prevents ingress of dust from below. This connection device 1 is like the connection device of Fig. 8 built up. Below, therefore, only differences to the variant of Fig. 8 explained. It thus also indicates the second embodiment of the eccentric unit 22 Fig. 7 on (see Fig. 15b ). However, compared to Fig. 8 more of the contacts 9, in turn formed as IDC contacts in three parallel rows - provided, which serve for contacting conductors or wires of the flat cable 50. Correspondingly, more of the contacts 72 are provided for connecting conductors which are provided to be connected to one of the conductors of the flat cable 50, respectively.

The connection device of Fig. 15 also has a cover 77, which covers the eccentric unit 22 from above, so that it is well protected. In particular, such a penetration of dust is well avoided, which prevents fouling of the eccentric unit in the elevator shaft. The cover 77 is preferably attached directly to the eccentric unit 22 and extends in the mounted position on the base housing 2 preferably between the webs 16, 17. Therefore, preferably corresponds to the width of the cover 77 in the Y direction the distance Y1 (see Fig. 3 ) between the webs 16, 17 of the cover 4. At the eccentric 22, the cover 77 is preferably fixed in a form-fitting and / or latching. The eccentric housing may further include a Abstützkontur 27 b, which extends obliquely and which serves to stabilize the cover 77 and support. The cover 77 also optimizes the design of the connection device 1, since it is adapted to the contour of the webs 16, 17 on the base housing. In addition, it secures one or more elements of the eccentric unit such as its eccentric roller 23 against a failure before the eccentric unit is mounted.

To the base housing 2, here at its cover section 4, a strain relief contour 78 is formed, which in the main direction of extension of the flat cable 50 to be contacted (FIG. Fig. 15d) protrudes. At this strain relief contour 78 - here in the manner of a partial collar - a cable tie is fixed (not shown here). At the Bodenabdeckplatte 3 ', a corresponding partial collar 78' may be formed. The partial collar 78 and the partial collar 78 'are limitedly movable relative to each other perpendicular to the main extension direction of the flat cable 50. With the cable tie, guided by the partial collar 78 and 78 ', the flat cable 50 can be fixed in a simple manner by clamping. Such a strain relief for the flat cable 50 can be realized in a simple manner.

The cover 77 and the Zugentlastungskontur 78 for the strain relief can be implemented on all variants of the invention shown.

On the cable support plate 18, one or more webs 79 are provided. Preferably, these webs 79 are releasably attached. They extend perpendicular to the plane of the cable support plate 18. They are located at points at which one or more wires of the flat cable are interrupted, for example by a punched - so that, for example, a safety circuit function can be realized.

The Bodenabdeckplatte 3 'preferably extends in width only or at least over the width of the flat cable to be contacted 50 ( Fig. 16d ). After the variant of the connecting device of Fig. 15 is no electronics, in particular no electronic circuit board for processing signals to the connection device provided.

The problem, a variant of the type Fig. 15 To supplement an electronics, in particular an electronic circuit board for processing signals to the connection device is achieved in that an electronics housing with electronics, in particular an electronic circuit board is created that can be attached to the base housing 2 and fixed thereto and this electronics ,

Such an arrangement is in Fig. 16 a) to d) been implemented. Thereafter, an electronics housing 81 with electronics, in particular an electronic circuit board 82, created that in the main extension direction of the flat cable to be contacted 50 is attached to the base housing 2 and fixed thereto. At the electronic circuit board one or more printed circuit board connectors 83, 84 are formed. They allow the connection of cables 85 or conductors.

To the terminal contacts 77 of the connection device 1 conductors are connected according to he illustrated variant, which thus connect wires or conductor of the flat cable 50 which are connected to the corresponding contacts 9 of the connection device 1 via one of the PCB connector 83 with the electronic circuit board 82. The cable 85 is connected as an output or input to another of the PCB connectors 84.

The electronics housing 81 is formed here in a preferred embodiment relatively flat and elongated and is perpendicular to the flat cable significantly flatter than the base housing 2 of the connection device 1. It may have a cover 86 to the connection of conductors and / or cables and / or plugs facilitate.

Preferably - bar not mandatory - the electronics housing 81 is simply fixed to the base housing 2 latching. For this purpose, it is preferably pushed in the main extension direction of the flat cable 50 (arrow P) and locked to the base housing 2, to which this housing corresponding locking means (to see here is only one of these locking means: 87).

The electronics housing 81 could also be mounted below, above or on the other side of the base housing. The variant of Fig. 16 is particularly advantageous because the electronics housing 81 is housed compactly close to the flat cable 50. Between the electronics housing 81 and the base housing 2 also directly corresponding, plug-in connector could be provided (not shown here).
