Description

Wiring an elevator shaft.

Field of the Invention

The present invention relates, in general, to a wiring of the elevator shaft and, for example, a wiring of the elevator shaft with a flat hybrid cable and devices connection as well as a hollow wiring installation system of the elevator

Background of the invention

In the wiring of elevator installations, you must connect, on the one hand, the elevator car to power lines supply and control, which is normally done through a mobile cable, for example a cable that hangs below the elevator car On the other hand, an elevator wiring it also usually includes one or more cables that are fixedly installed in the elevator shaft and running from floor to floor These serve on each floor for sensor connection of elevator doors, actuators of elevator doors and / or transport and signaling devices located in the floors (with which an elevator user can signal a wish of transport, and receives information on the acceptance of the desire to transport, the momentary state of the elevator, the address of elevator gear, etc.). For these purposes, they are installed usually in the elevator shaft a data bus line and a low voltage supply line. The information about the Door security can be transmitted in a coded way by middle of the data bus line. In some facilities, in the elevator shaft is also installed a circuit of its own door security. The latter joins in a serial connection the door switches located on each floor to each door corresponding elevator, which are open with the door of the elevator open and closed with the elevator door closed, and thereby interrupting the door safety circuit when One of the elevator doors is open. So far it has been used, instead of a data bus - as usual formerly- a wire harness with individual conductors for each device connected; They are also conventional, partially, mixed forms, in which some devices are connected individually, others are connected by middle of a data bus, so that then a Wire harness with individual conductors and a data bus. In Some installations also have a power cable high voltage (typically for supply voltage, for example 200 volt alternating voltage) in the gap, which typically runs without ramifications on the floors from the elevator shaft to the excavation ditch (and serves, for example, for a disconnection of security of the elevator when surpassing the last floor), although you can also present in some facilities ramifications to the floors for the supply of floor devices with high voltage current. Finally, a supply line usually runs in the elevator shaft for lighting of the gap that supplies the lights distributed along the hole.

Usually, the individual cables are joined together to form one or more cable harnesses, which in the construction of an elevator are individually shaped in situ or pre-assembled in the workshop by the manufacturer, and then simply mounted and connected on site in the elevator shaft.

A document EP0187876B1 is known as a installation system for elevators, in which a data line formed by means of a flat cable with a voltage supply Two conductors are provided for laying in the hollow of the elevator, which contacts each floor with the help of connectors Pluggable with cutting tips and connected to floor modules uniforms on each floor. It is mentioned that three are available data line conductors for the transmission of three signals specials, such as "firemen", "special march", and "output signals from a door control". In the case of the latter should be special signs for jobs of maintenance on the doors.

Description of the preferred embodiments

Fig. 1 schematically shows a wiring of the elevator shaft in an elevator shaft. Prior to A detailed description of Fig. 1 is found first place, different explanations of the embodiments.

In the embodiments, the flat cable hybrid is pulled into the elevator shaft in such a way that it passes through several or all floors of the elevator. Present at least one data line and a door safety circuit. Flat cable hybrid presents a fundamentally flat, approximately unlike a round cable. The concept of "cable flat ", however, does not imply that all drivers of the flat cable must be in a flat (for example, the conductors of a crooked data line are not arranged in the fixed plane by the flat cable). In the embodiments, however, the center lines of the different lines (eg the center line imaginary in a crooked data line) are in the plane fixed by the flat cable. The concept of flat cable either it implies, for example, that the surface of the cable must be flat; on the contrary, in some embodiments, the cable has the shape of individual wires in a circular shape in its section transverse, which are joined by nerves with a formation flat. With the addition of "hybrid", it is expressed in the forms of embodiment that the flat cable has at least two lines of different types, for example, the mentioned data line and the door safety circuit.

The connection devices can be placed as exits of the floors in the flat hybrid cable through, and it can guide them to make contact with some or all drivers that run inside. In the ways of embodiment, the connection devices are made up of such way they perform a shunt on the through conductors without that a separation of these conductors is necessary - with the exception of the safety circuit.

In the safety circuit, on the contrary, for the achievement of a serial connection of the switches the doors located on each floor in the corresponding door of the elevator, there are other relationships, and in particular, it interrupts the least one driver of the door safety circuit in the region of the connection device. The connection device establishes contact for the achievement of the serial connection with the interrupted driver of the door safety circuit to both sides of the interruption position.

In addition to the mentioned data line and the mentioned door safety circuit, the hybrid cable it presents in some embodiments, additionally, a line Low voltage supply. Some of the embodiments of the connection device are shaped in such a way that They also make contact with this low voltage supply line. The entire line serves, for example, for the supply of the devices arranged on each floor, such as the sensors of the elevator doors, the actuators of the elevator doors, the transport and signaling devices of the elevator, control devices, etc.

In some embodiments, the flat cable hybrid additionally presents a high current line tension. In the high voltage current line it is placed, by for example, the voltage (s) of a supply network single-phase or three-phase voltage with for example 220V / 380V of Nominal voltage. This line runs in certain facilities from the digging trench to the head of the elevator shaft, without be derived on each floor. For example, it serves for safety disconnection of the elevator when exceeding the floor more top, or for the supply of high current appliances tension arranged in the head of the hole. The device of connection is shaped for these embodiments of such so that it does not foresee any contact, or at least no contact coercive of the high voltage current line, so that You can go through it without any derivation. In other embodiments, the connection device or devices are shaped in such a way that they also make contact with the line of high voltage current, to supply high current voltage to appliances arranged on floors or devices of lighting.

The door safety circuit is formed in some of the embodiments for low voltage (for example 20 V or 48 V), in other embodiments for the rated voltage of the high voltage power supply network (for example 220V). In some of the embodiments, the corresponding conductor of the safety circuit to be interrupt in the region of the connection devices, run on the outside of the hybrid flat cable. This conformation facilitates the accessibility of the driver to be interrupted, for example in embodiments in which the interruption of the driver must be carried out before authentic placement of the connection device on the hybrid flat cable.

In some embodiments with conductors interrupted from the safety circuit, which runs external to the hybrid flat cable, the cable cover has a perforation or notch between this driver and the next driver. This one works for easy removal of a cut portion of the conductor in the area in which the connection device must be placed at cable. In other embodiments, the interruption and / or the Safety circuit contact take place through the cover of the cable.

In some of the embodiments, the Data line presents at least two drivers. It is about example of a data line, in which a couple of two drivers of the same type that run the same distance It forms a symmetrical line. In some of the ways of realization, the conductors of a couple run parallel between Yes being on a plane. To reduce asymmetric couplings in the data line, in other embodiments, the drivers of a couple are twisted together (or also several couples, as in the case of a star quadrant line).

In some embodiments, the contact of the data line is carried out by means of penetration both of the cable cover as of the conductor insulators. In These embodiments do not remove the cable cover before of the application of a connection device in the region of the data line In other embodiments, on the contrary, it you must remove at least the cable cover on the data line; contact with the data line is carried out in this case, by example, only under the penetration of the insulators of the drivers. To more easily remove the cable cover which is around the data line, it presents in some embodiments in the data line a perforation or notch.

As mentioned, in some ways of realization the contact of some or all of the hybrid flat cable conductors without removing insulation from the insulators of the conductors by means of the penetration of the insulators of the conductors. In some of these ways of realization, the contact of some or all the conductors is also performs without removing the cable cover, causing the cable cover is also penetrated. To do this, in the connection device are arranged penetration contacts suitable in places where the corresponding drivers that have to be contacted are found in the flat through cable. To ensure a unique definition of the relative position of the connection device and flat cable, in some of the ways of realization, the outer contour of the hybrid flat cable is complementary to the internal contour of the connection device; in In this case, the contours are chosen in such a way that the device connection can only be contacted in a unique position in relationship with the hybrid flat cable.

This type of pinch contact causes certain difficulties on lines whose drivers do not have a invariable position in relation to the outer contour of the cable plane in the longitudinal direction of the cable, as is the case, for example, in the data line in those embodiments with crooked conductors. In some of the embodiments with twisted data line, the hybrid flat cable presents, by example, on the cable cover, marks that are repeated on the longitudinal direction of the cable, which indicate for installation where the connection device for the contact should be placed of the twisted data line in the hybrid flat cable (or -in other embodiments - where the device should not be placed Connection). Alternatively, the hybrid flat cable presents in other embodiments records that are repeated in the address cable length (for example, in the form of elevations or notches in the cable cover) that allow a contact of the data line with the connection device only in points appropriate (which can also be done through the registration prohibits contact at inappropriate points). Points suitable for making, characterized by means of the brand or prefixed by means of registration are, for example (in the case of contacts in the direction transverse to the plane fixed by the cable flat) those points in the longitudinal direction of the cable in the that twisted conductors are arranged, respectively, parallel to the plane of the flat cable.

While in some of the ways of realization the drivers of the crooked data lines are twisted together in helical form, in other forms of realization a special torsion is performed in which the conductors run parallel in some sections (i.e. no twisted), according to what this type of sections follows a twist of the two conductors (for example 180º or a smaller angle, for example, 90º). The conductors are arranged in a suitable plane for contact in parallel sections (or in some of the parallel sections), for example in the plane of the flat cable or parallel to this one. In some of these embodiments They are provided on the outside of the cable cover trademarks or records mentioned above, which indicate where are the parallel sections suitable for the contact (or -in embodiments where brands or records indicate points not suitable for contact - where not these parallel sections are found).

In other embodiments with a line of twisted data (twisted helically or twisted with sections parallel), the hybrid flat cable does not have any type of marks or records of the type mentioned. On the contrary, in this case it make the contact of the conductors after they have taken without cover and to a position suitable for Contact. In some of these embodiments, the device of connection presents for this in the region of the data line a clamping contour that holds the conductors without cover in one defined position suitable for the contact.

In some embodiments, the circuit of security must be interrupted before the placement of the connection device on the hybrid cable, which, for example, is Can perform manually. To ensure that the circuit of security is really interrupted at the point of placement in the connection device, in some of these ways of embodiment the connection device is shaped in such a way that this - or the part of the connection device necessary for the contact - can only be placed in the installation on the cable hybrid plane when the safety circuit has been interrupted previously at the point of placement. To do this, for example, you can serve an insulating projection disposed at a suitable point in the connection device, which acts at the breakpoint of the corresponding driver of the safety circuit, in such a way that when the driver is not interrupted yet, the device of connection or the part that serves for the contact of the device connection cannot be placed.

In other embodiments, by the otherwise, it is not necessary to interrupt the safety circuit before placing the connection device. For him on the contrary, in this case the connection device is shaped in such a way that he himself, when placed on the hybrid flat cable, interrupts the safety circuit. In some of these ways of It is necessary to remove the cover of the driver to be interrupted; the connection device is arranged only for driver interruption without cover, and not, however, of the driver with cover. In other ways of embodiment, it is not necessary to remove the driver cover that it has to be interrupted; the connection device is capable in this case of interrupting the corresponding driver in state no covered. For example, the connection device is equipped with a cutting blade and with a penetration projection, which are shaped in such a way that when placing the connection device (or its part that serves for the contact), first, the cutting blade cuts the conductor with the insulation of the conductor and if necessary the cable cover, and then the penetration projection curves out the conductor and penetrates into the breakpoint created in this way.

In some embodiments, the device connection is built in two or more parts, being at least two parts of the connection device arranged to surround the flat hybrid cable. In some embodiments, the contact It is then carried out by means of screwing or introduction of pressure penetration contacts in the flat cable surrounded. In other embodiments, the contacts of penetration are fixedly arranged in one of the parts of the connection device; the contact of the conductors takes to then place with the placement of this part on the flat cable and the clamping of this part in the other part that makes up the piece opposite of the connection device.

In some embodiments, the device of connection is shaped in such a way that with the clamping of the mentioned parts you can also perform a wall mount of the connection device. For example, for fastening they serve screws protruding on the floor part of the device connection, and with it can be used for wall mounting.

Usually the elevator gaps They are equipped for safety reasons with lighting hole. This typically serves a cable pulled especially in the hollow, which supplies lights arranged at uniform distances (for example on each floor or every two floors). In one of the ways of realization present, the lighting of the gap, on the contrary, It is integrated in the wiring of the hole described here. For it, The lights are arranged in the connection devices. The connection devices are shaped in such a way that the lights are connected with the placement of the connection device in the hybrid flat cable without additional installation so refers to the power supply. For example, it can be provided with a flat conductor circuit (low supply voltage or voltage) for the supply of the lights; alternatively, the lights may be powered by the line General low voltage or high voltage current supply on the flat cable; its connection and disconnection is carried out then, for example, by means of the controlled coupling to the data line The lights, for example, are light emitting diodes (LEDs), since these, as a result of their energy consumption relatively reduced, its reduced heat emission and its voltage reduced supply are especially indicated for the arrangement in the installation system connection device described

Turning now to Fig. 1, this schematically shows an embodiment of a wiring of the elevator shaft 1 in an elevator shaft 2. The wiring 1 passes several floors of the elevator, of which in Fig. 1 are two shown (these are designated 3 'and 3''). The wiring 1 of the embodiment shown in Fig. 1 comprises a flat hybrid cable 4 and a high voltage current cable 5 running separately from it, for example, in the form of a round cable. The cables 4, 5 run in the elevator shaft 2 from the excavation ditch 6, passing along the floors 3 ', 3'', to the head of the elevator shaft 7. The hybrid flat cable 4 comprises a data line 8 two-conductor (which, for example, is operated as a data bus), a two-pole low voltage supply line 9, and a door safety circuit 10. The latter is formed by means of a conductor connection of door switches 11 and a return conductor 11 (which is connected, for example, to
land).

The conductors of lines 8, 9, 10 mentioned are arranged in the flat cable cable plane 4, the conductors of the safety circuit of the doors 10 on the outside, and the data bus 8 and the line Low voltage supply 9 inside. The data bus 8 It is represented in Fig. 1 with conductors that run parallel Fig. 1 serves at the same time for the graphic illustration of embodiments with bus drivers of data that run parallel (i.e. not crooked), as well as schematic abstract representation of embodiments with Twisted data bus drivers.

In each of the floors 3 ', 3' 'is planned, respectively, an exit from the floor 13 ', 13' '. This is shaped by means of a connection device 14 ', 14' 'placed in the hybrid flat cable 4 and 15 ', 15' 'output lines extracted from East. With the help of the connection device 14 ', 14' ', the conductors are punctured to all lines 9, 10, 11 of the cable plane 4 to the junction conductor of the switches of the doors 11 without interruption; the output lines linked with these Drivers, with it, are branching lines. The driver of junction of the door switches 11, however, is interrupted in each of the connection devices 14, 14 '', and in connection device 14 ', 14' 'is provided, respectively, in front of and behind the breakpoint 16 ', 16 '', a connection to an output line, respectively. These last output lines are connected respectively with the two terminals of a door switch 17, 17``. The switches of the doors 17 are coupled with the elevator doors of such so that they are open with the door open and closed with the door closed. In the representation according to Fig. 1 is represented by way of example a case in which the door is open on the upper floor of the two floors 3 ', 3' 'represented; correspondingly, the upper door switch 17 '' it is open, while the lower 17 ', on the contrary, is closed. With this, in the door safety circuit 10 a serial connection of all the circuit breakers is made doors 17, the safety circuit of the doors 10 when -as in the case represented in Fig. 1- no all elevator doors are closed. A starting line 15 ', 15' 'branched from the return conductor 12 serves, by example, for the grounding of the switch housing the doors 17 ', 17' '. The rest of the output lines 15 ', 15' 'join the elevator transport and signaling devices 18 ', 18 '' located on each floor 3 ', 3' 'with data bus 8 and with the low voltage supply line 9.

For example, at the height of the ditch of excavation 6 is provided an elevator control apparatus 19 which is connected to all lines 8, 9, 10 of the hybrid flat cable 4 and, in some embodiments, with the power cord of high voltage 5. It controls the elevator and devices 18 depending on the signals received from them, as well as the fact that the safety circuit of the doors 10 is closed or disrupted.

Fig. 2 shows another embodiment of a wiring of an elevator shaft 1 similar to Fig. 1, in the that, however, the high voltage current line (designated in this case with the number 5 ') it is not guided as a special cable, but it is part of the hybrid flat cable 4. So correspondingly, the connection device 14 also envelops the 5 'high voltage current line. In some ways of embodiment, this runs through the connection device 14 without taking takes. In other embodiments, the connection device 14 is shaped to also take the 5 'high voltage current line; the corresponding shots and the branching lines are plotted in Fig. 2.

Another difference regarding the way embodiment of Fig. 1 (which is independent of the conformation mentioned of the high voltage current line 5 as part of the hybrid flat cable 4), lies in the fact that for the circuit of safety of the doors 10 a return conductor is provided 12 separated from the ground line, which is arranged in the cable hybrid plane 4, in this case, for example, between the driver of junction of door switches 11 located outside and the data bus 8.

Fig. 3 illustrates driver interruption of connecting the door switches 11 in the device connection 14. To do this, on connection device 14 on the breakpoint region 16 a path is planned insulator 19, on whose two sides a contact of the conductor 20 makes contact, respectively, with the ends of the connecting conductor of the door switches 11 interrupted, and joins them with the output lines 15.

Fig. 4 shows a side sectional view of an embodiment of the connection device 14 that only It can be placed on hybrid flat cable 4 when the conductor of junction of door switches 11 has already been interrupted previously at breakpoint 16. In the form of embodiment shown in Fig. 4, the connection device 14 It is built from two construction groups, which in state mounted wrap the flat cable 4 on the bottom or top of the flat cable. In this case it is a basic part 21 and a socket part 22, between which the flat cable 4 passes. For all the drivers to be contacted, in the part of take 22 conductive contacts are arranged, of which in view of side section of Fig. 4 only the two contacts can be seen of the conductor 20 for the contact of the union conductor of the door switches 11. The socket part 22 according to Fig. 4 it is shaped in such a way that it can only be placed on the cable hybrid plane 4 when it has previously been trimmed at the point corresponding flat cable 4 a piece of the junction conductor of the door switches 11, for example with the help of a two-sided cutting device. For them, the insulating path 19 arranged in the socket part 22 is shaped as a projection penetrating the break point 16 of the junction conductor of the door switches 11. In other embodiments a corresponding projection is formed, instead of in the part from socket 22, in basic part 21, which already prohibits an introduction of the flat cable 4 in the basic part 21 in case there is no trimmed the mentioned piece of the union conductor of the door switches 11.

In the case of conductive contacts 20, it concerns, for example, "U" shaped terminal blocks, which they wrap the driver 23 of the driver to be contacted at place the socket part 22 on both sides, thereby sectioning the insulation of the conductor, and contact the conductor that runs in the center of the driver 23. Alternatively, the contacts conductors can be in the form of contact bolts (for example according to the type described in DE 201 11 496), which penetrate conductor insulation and establish contact thanks to fact that they are placed with a contact tip in the conductor that has to be contacted, or even penetrate it. The terminals of mentioned cut or contact bolts are arranged, by example, in a fixed way, in the socket part 22. In other forms of embodiment, the conductor contacts are shaped as screwed contacts arranged in socket part 22, which by example are entered by turning manually with a screwdriver after placement of socket part 22 in the flat cable 4, and thereby penetrate the insulation of the driver and make the driver contact with a contact tip (for example according to the type described in EP 0 665 608 A1). All embodiments of conductor contacts 12 they are preferably shaped in such a way that they can not only penetrate the corresponding conductor insulator but also the flat cable cover 24 4. In these embodiments it is not it is necessary to remove the flat cable cover 4. In other forms of embodiment the flat cable cover 4 is removed at least in the region of some of the lines before the placement of the connection device 14. For example, in the case of the line the one that has to be removed the cover, it can be the bus of 8 data and / or the junction conductor of the circuit breakers of the gates 11. For lines 5 ', 8, 9, 12 interns to be punctures a conductor contact 20 is sufficient for each connection device 14 (as shown in Fig. 1 and 2), while for the contact of the connecting conductor 11 which has if interrupted, a conductor contact 20 is provided in front of and behind the insulating path 19 in the device connection 14.

Fig. 5 shows another embodiment in which the junction conductor 11 is interrupted with the placement of the socket part 22 in the flat cable 4 inserted in the part basic 21. The socket part 22 is equipped with a cutting blade 25 which is made, for example, of plastic insulator (and if necessary, it can be made of one piece with the take part 22). The insulating path 19 is carried out in this embodiment as a beveled projection; in this case not only serves to penetrate the breakpoint 16 of the conductor of junction 11, but also to fold out this when placing the socket part 22 from the plane of the plane plane towards the basic part 21. For this, the basic part 21 has a notch 26 complementary to insulating path 19, that is, also runs inclined. Although basically a single section of junction conductor 11 for separation electric (for example using a cutting blade made of insulating material), in the embodiment according to Fig. 5, with this, the connecting conductor is not only sectioned, but the sectioned end is pressed with the help of insulating travel 19 out of the plane of the cable to the notch 26 of the basic part twenty-one.

In some embodiments, the driver junction 11 must be sectioned in a state devoid of the roof; In these embodiments, the cutting blade 25 only has the mission of sectioning the connecting conductor 11 transversely. Correspondingly, in these embodiments it is enough a cutting blade 25 that is arranged transversely with respect to the direction of the connecting conductor 11. The embodiment represented in Fig. 5, on the contrary, it is indicated to section the connecting conductor 11 also in the state in which the cover has not been removed. In the way of embodiment depicted, the cutting blade 25 not only has the mentioned mission of a section of the junction conductor 11, but that -to make possible the bending of the cable end separated from the cable out of the plane of the cable- also has the mission of section the nerve-shaped junction of the cable cover of the junction conductor 11 with the adjoining conductor in the direction cable length For this purpose, the cutting blade It has a cutting edge that is essentially "L" shaped, the long side of the "L" inclined in the longitudinal direction of the cable.

Figs. 5a and 5b illustrate the process of placement of the socket part 22 and the section caused by that of the connecting conductor 11 in two different stages: Fig. 5th shows the situation at the beginning of the placement process, and the Fig. 5b shows the situation with the taking part 22 completely placed. At the beginning, the cutting blade 25 penetrates the junction conductor 11 and in the nerve-shaped junction of the cover with the adjacent driver, and section both with a pressure increasing part of socket 22. In the subsequent course, the insulating path 19 of one of the ends of the connecting conductor 11 acting as a penetration projection acts at the point of notch gap 26. Additionally, the contacts of conductor 20 penetrates conductor 23 and contacts the conductor of conductor 23. In the final state (Fig. 5b), conductor 23 of the junction conductor 11 is curved out of the cable plane until such that the sectioned conductor ends are no longer oriented towards each other, which guarantees a separation safe electric.

Fig. 6a, 6b and 6c show different shapes of conducting conductive contacts 20 in sectioned views lateral partial connection devices. Contacts conductors 20 are arranged in two of the embodiments mentioned (specifically according to Fig. 6a and 6b) fixedly in the socket part 22, while the third embodiment (Fig. 6c) provides for a mobile provision in socket part 22.

In the first embodiment according to Fig. 6a, the conductor contact 20 'is formed by means of a cutting terminal (illustrated in perspective). In the realization shown here, the cutting terminal wraps the conductor 23 released previously of cover 24, sectioning in the course of the placement of socket part 22 conductor insulator 27 and thus contacting the conductor 28 that is in its inside. In other embodiments it is also possible contact a cut-off terminal of the type shown on the conductors that the cover has not been removed.

In the embodiment according to Fig. 6b, the 20 '' conductor contact is formed as contact pin, that when placing the socket part 22 penetrates the cover 24 and the conductor insulator 27, and with its contact tip 41 penetrates into the driver 28, and thereby contacts this one. In the way of embodiment shown in Fig. 6b, it is not necessary to remove the cover; other embodiments similar to Fig. 6b are formed for the contact of conductors 23 in which previously removed cover; correspondingly, in these cases, the contact bolt does not need to penetrate the cover 24.

For the embodiment according to Fig. 6c what is said for Fig. 6b, with the indication that in Fig. 6c is provided as a conductor contact 20 '' 'a screw of contact, which is seated in a threaded hole in the part of socket 22. In this embodiment, with the contact screw removed by turning, contact with the placement of socket part 22. On the contrary, the screw is determined to be introduced by turning after the placement of socket part 22 on flat cable 4, penetrating with its contact tip 41 the cover 24 and the insulation of the driver 27, and contacting driver 28.

The conductor contacts 20 ', 20' ', 20' '' they are electrically connected with the output lines 15 corresponding, respectively (Fig. 1). The forms of embodiment shown according to Fig. 6a to 6c are suitable for the taking different lines 5 ', 8, 9, 10. When using a data bus 8 shielded, the conductor contact 20 may be equipped with an insulator (such as the one described in DE 201 11 496 U1) to avoid a short circuit with the shield of the bus data above the region with which you contact the driver 28.

To make possible in embodiments according to Fig. 4 a simple manual setting of the point of interruption 16 (Fig. 4), in some embodiments, such and as shown in Fig. 7, the cable cover 24 which conforms a nerve is perforated between the junction conductor of the door switches 11 located outside and the rest of conductors of the hybrid flat cable 4 in the direction length of the cable or, in other embodiments, is weakened in the cross section (for example with a notch). The length of drill holes 42 or regions of weakening corresponds approximately to the length of the breakpoint 16 to be created. Through a simple separation of the connecting conductor 11 in which it has not been removed the cover at the two ends of a hole 42 of this type (for example with the help of cutting pliers Single diagonal or a two-sided cutting device adjusted to a suitable length) can be easily separated from flat cable the piece of conductor to be removed from the perforation 42. The connection device 14 (for example according to the embodiment of Fig. 4) with the insulating path 19 that penetrates the separate point can then be placed in a simple mode

Fig. 8 is a plan view from above of a section of a hybrid flat cable 4 showing sectioned the data bus 8. Unlike the embodiments of the Fig. 1-3, in this case the data bus 8 is located outside the flat cable 4 (for example in the location of the 5 'high voltage current line of Fig. 3). In the embodiment represented in Fig. 8 is the case of data bus 8 of a matched twisted line helical. If the data bus 8 is taken by means of penetration of conductor contacts 20, for example, in the direction perpendicular to the plane of the flat cable (i.e. perpendicular to the drawing plane of Fig. 8), then they are only suitable for taking those sections of the cable 4 in which the two data bus conductors 8 are arranged next to each other in the plane of the flat cable, although not those regions in which Be arranged one above the other. To show the installer the suitable points of the flat cable 4 for the socket, the cover of the cable 24 is provided with suitable marks 29 on the outside that repeat over uniform distances. In connection device 14 a suitable opposite mark is applied, having to position the connection device 14, such that, for example, the two marks are aligned on the flat cable 4 in the direction longitudinal. Naturally, the 29 mark may also be arranged at another point relative to the torque of the data bus 8, for example at the points where the two drivers are arranged one above the other, or in each intermediate position. He desired result - that is, a data bus 8 taking only in the points of the shot-track is achieved by means of an arrangement proper relative of the marks on the connection device.

A similar view shows Fig. 9, although another embodiment, in which instead of marks are provided 30 records on the outside on the cable cover 24. These, for example, have the shape of protrusions in those points at which as a result of a crossing of the drivers Data bus 8 cannot take any shots. Through proper conformation of connection devices 14 -by example the lack of complementary notches to the projections 30 in connection devices 14- the basic part is achieved 21 and the taking part 22 can only be closed at those points around the flat cable 4 in which the conductor contacts of the data bus will not stop at a crossing point.

Another difference between Fig. 8 and 9 lies in the fact that the data bus drivers 8 are not crooked helically (as in Fig. 8), but run respectively along long sections in parallel and being arranged in the plane of the cable. This parallel course in some sections it prolongs the sections where it can be done one take and thus facilitate the data bus take. Naturally marks according to Fig. 8 can also be used on a bus data with parallel sections according to Fig. 9 and records according to Fig. 9 also in the case of a shapely twisted data bus helical according to Fig. 8. Both marks and registers according to Figs. 8 and 9 allow a data bus 8 to be twisted to through the cover 24 of the flat cable 4, ie the cover 24 can remain on the flat cable 4.

In other embodiments (see for example the following Fig. 11), on the contrary, the cable cover 24 of the data bus 8 must be removed before taking the bus from data 8 (also on the outer edge of cable 4). For facilitate this, in the embodiment shown in section cross section in Fig. 10, the cable cover 24 is provided with a notch 31 (or weakening in the cross section) that runs longitudinally. This facilitates a separation of the cable cover 24 arranged above data bus 8 before of placing a connection device 14. To separate easily the separate part of the cable cover 24 of the cable cover 24 above the rest of lines 10, given the case 5 ', 9, of the hybrid flat cable 4, is shaped additionally on cover 24 between data bus 8 and the rest of lines 10, given the case 5 ', 9, a reduction of the section cross-shaped neck, for example, in the section cross. In other embodiments, this reduction of cross section is formed, for example, by means of perforations (similar to those shown in fig. 7).

Fig. 11 shows an embodiment of a flat hybrid cable 4 and a connection device belonging to this one as a developed representation. The flat cable 4 it presents, on the outside, respectively, a conductor of junction of door switches 11 as well as a bus 8 data in the form of a twisted paired line. In between run a return conductor 12 (which together with the junction conductor 11 forms a safety circuit of the doors), a 5 'high voltage current line (which in this case is made up of four conductors, for example for three-phase alternating current transmission of for example 380 V), as well as a low voltage supply line 9. The cable plane 4 does not have a uniform thickness in the cross section, but between some of the drivers (for example between the bus of data 8 and the low voltage supply line 9) has nerves of reduced thickness, and thus has an outer contour corresponding with notches. This outer contour is asymmetric with respect to a 180º turn of cable 4 around the axis length of the cable, as well as with respect to a 180º turn that swap the beginning and end of cable 4.

The connection device 14 can be mounted on the embodiment shown in Fig. 11 from three parts, namely a basic part 21, a socket part 22 and a cover part 33. The first two parts mentioned, that is, the basic part 21 and the socket part 22, are shaped to, in state mounted, tightly wrap flat cable 4 or to Contact some or all of the drivers located inside. For this, the basic part 21 and the socket part 22 have a inner contour that is complementary to the outer contour of the cable 4. As a consequence of the asymmetry mentioned above, connection device 14 can only be mounted on one of four Possible positions, essentially, on the flat cable 4. Additionally, by means of an insulating path 19 in the form of a outgoing, similar to Fig. 4, it is guaranteed that the device connection 14 can only be mounted on flat cable 4 when a corresponding section of the driver has previously been separated of connection of the switches of the doors 11. Unlike the embodiment of Fig. 4, the projection that forms the insulating path is formed here in the basic part 21, and it reaches a corresponding notch 34 in the socket part 22

In the embodiment shown in Fig. 11, the cable cover 24 above the data line 8 has been to withdraw along a certain length that is somewhat shorter that the length of the connection device 14, at the point of connection, before connection device 14 is placed. This makes it possible to rotate the twisted conductor of the data line 8 in this region and introduce it in a clamping contour 34 in the basic part 21, which has for example the form of three blocks that they run parallel in the longitudinal direction of the cable, and thanks to this it guarantees a separation and a parallel position of The drivers mentioned. In some embodiments in the socket part 22 an opposite contour is provided correspondent.

In socket part 22 they are arranged so fixed different conductor contacts 20, in this case in the form of "U" shaped cutting bolts. In the embodiment example shown in Fig. 11 are two of these contacts of conductor 20 in front and behind notch 34 for contact of the junction conductor 11 interrupted, as well as other contacts of conductor 20 in the position of the conductors running in the clamping contour 35 of the data bus 8, as well as of the Low voltage supply line conductors 9 (contour clamping 35 has, for example, suitable slots to allow the passage of cutting bolts). The output lines 15 guide, respectively, from the conductor contacts 20 towards the Exterior.

The cover part 33 is equipped with two protruding sleeves 36 that when placing the lid part 33 they enter complementary holes 37 in the socket part 22 and in the basic part 21, and thanks to this guarantee a centering of the three parts 21, 22, 33 and, by lightly pressing these parts, a correct relative positioning of flat cable 4 and device connection 14 already before the conductor contacts 20 completely penetrate the flat cable 4. When using long screws protruding from the sleeves 36 at the bottom of the part Basic 21, wall mounting and clamping can be performed of the connection device 14 in a working step. And in particular, the cover part 23 presses through the rotation of the screws mentioned and of the tightening at the base (for example the wall of the hole of the elevator) the socket part 22 fixedly in the basic part 21, and the flat cable 4 that runs between them, thanks to which the conductor contacts 20 - already positioned correctly - penetrate the cable cover 24 and the corresponding insulator of the driver, and make contact with the driver's driver correspondent. In this case, a seal 38 is also compressed. surrounding the contact region, which is arranged, for example, in the basic part, which prevents the penetration of water and dirt into The contact region.

Fig. 12 shows an embodiment similar to Fig. 11, in which, however, on the lid part 33 a light 39 is arranged. This is formed, for example, by means of several LEDs (in this case four). For the supply of light stream 39, in the embodiment of Fig. 12, a pair of conductors 40 is provided. The socket part 22 is Equipped with 20 'conductor contacts specifically for making this pair of conductors 40. The tension taken with these contacts of 20 'driver, however, is not removed - as in the case of other conductor contacts 20- through output lines; by the opposite, at the top pointing towards the part of the cover 33 of the socket part 22 connectors are provided plug-ins that act in conjunction with plug-in connectors corresponding in the cover part 23. With the placement and the connection of the connection device 14 is made pair of conductors 40 and said union is established plugged in with the light 39. With this, the embodiment of the Fig. 12 makes it possible to install a through lighting of the elevator shaft, without doing so - except the equipment represented of cable and connection devices - be necessary No additional cost of installation for lighting of the hole.

The described embodiments provide wiring of elevator shafts that can be installed at a cost reduced work, being able however to adapt to relationships individual (for example, different floor heights) without a precondition
