Description

Wiring device for multi-conductor cable

Technical Field

The invention relates to a connecting device for connecting conductors of a continuous flat cable having a plurality of conductors, which are each optionally surrounded by an insulating layer and embedded in an overlying cable jacket, having a multi-part base housing which is designed to support the flat cable, wherein a plurality of insulation-penetrating contacts, in particular fork contacts or piercing contacts, are provided on the base housing in order to connect the plurality of conductors of the flat cable.

Background

Such a connection device with contacts penetrating the insulation is known per se. They are used to quickly and reliably wire flat cables having a large number of wires.

DE 3422607C 1 discloses a connecting device which is designed such that it can be slipped onto a flat cable only when the conductor wires or cores are interrupted beforehand in the slipped-on position and have openings in this region. In the region of the interruption, an appendage of one of the sections of the connection device engages the core wire. This serves to orient the position of the connecting device and ensures that it can only be installed if the corresponding opening is provided. The attachment additionally separates and insulates the two ends of the interrupted conductor from each other. This solution has proven itself, especially when used in narrow building shafts, because it can be operated simply. A similar solution is proposed in EP 1518812B 1, which provides for the use of a connection device of the type according to DE 3422607C 2 for elevator shafts, where, for example, the safety circuit is always interrupted.

EP 1936747 a2 discloses a connection device of the type described. The base housing is designed in multiple parts and has a base part and a cover part, which are also designed in multiple parts. A sliding cover is preferably provided which is guided movably on the base plate and has wedges on its inside which cooperate with the wedges of the carrier plate, wherein the carrier plate is pressed together with the cable and the receiving plate for the cable as a whole against the contacts penetrating the insulating layer. This embodiment is compact and at the same time still enables particularly reliable wiring.

Although the same type of structure as that of EP 1936747A 21 has proven itself. There is still a need for an improvement of this type of connection device, in particular with regard to simpler accessibility.

Disclosure of Invention

The task of the present invention is to solve this problem.

To this end, the invention provides a connection device for connecting conductors of a continuous flat cable, which has a plurality of conductors, each of which is surrounded by an insulating layer and is embedded in a superordinate cable jacket, comprising: a. a one-piece or multi-piece base housing designed to support a flat cable; b. providing a plurality of insulation-penetrating contacts on the base housing for contacting a plurality of conductors of a flat cable, c. providing at least one eccentric unit on the base housing, and providing the eccentric unit when contacting the flat cable, with which the flat cable can be pressed against the insulation-penetrating contacts until the contacts are contacted, the eccentric unit having an eccentric housing into which an eccentric roller is inserted, which is mounted rotatably in the eccentric housing and is supported in the base housing counter to the direction of the wiring during the wiring, the eccentric housing being movable relative to the base housing when the eccentric roller is rotated, so that the eccentric unit can press the flat cable against the insulation-penetrating contacts until the flat cable is contacted therewith.

At least one eccentric element can be provided on the base housing (or already provided during the connection) with which the flat cable can be pressed against the insulation-penetrating contact until one or more of its conductors are connected. The connection of the flat cable is thus designed to be simple and without problems.

The eccentric unit particularly preferably has an eccentric housing, into which an eccentric roller is inserted, which is mounted rotatably in the eccentric housing and which is supported in a bearing-like manner against the direction of the cabling during the cabling in or on the base housing, the eccentric housing being moved relative to the base housing during the rotation of the eccentric roller, so that the flat cable can be pressed by the eccentric unit against the insulation-penetrating contact until the contact is closed. The eccentric element unit thus constructed is very compact in size and enables the conductors of the flat cable to be brought into contact with the penetrating insulating layer in a relatively simple and reliable manner.

In this way, according to one specific embodiment of the invention, a connection device is achieved in which the contact plate unit is designed as a circuit board unit having at least one circuit board which is placed on the base plate, wherein a cover plate is always placed on the circuit board in the region of the insulation-penetrating contacts, said cover plate having openings, in particular slots, which penetrate the cover plate at least partially, and the insulation-penetrating contacts project through said openings, said cover plate having recesses for receiving and supporting the base parts of the insulation-penetrating contacts when the insulation-penetrating contacts are closed. This makes it possible to easily support the high forces occurring when the contacts penetrating the insulating layer are connected over a large area on the circuit board, even on components located underneath the circuit board, in order to protect the circuit board.

It is advantageous if two or more eccentric units are also guided on the housing in a displaceable manner, in particular in a translatory manner, in the main direction of extension of the flat cable, in order to switch the flat cable at different positions in its longitudinal direction. It is advantageous here if the housing of such a connection device can be connected to a form-locking (and/or force-locking) structure, for example to one or more corresponding geometries of a dovetail connection.

According to one embodiment of the invention, a punch is attached to the connecting device in the main direction of extension of the flat cable for cutting one or more conductors of the flat cable. Since the punch is not integrated in the housing of the connecting device, but is formed separately therefrom, it is possible to provide the punch only in a targeted manner if the conductor has to be cut off, for example, to implement a safety circuit. It is particularly advantageous if the connecting device and the punching device have corresponding positive-locking structures, i.e. one or more corresponding grooves and tongues that can be inserted into one another, on which the connecting device and the punching device are arranged in the main extension direction.

Detailed Description

Fig. 1 shows a perspective view, while fig. 2 shows an exploded view of a first embodiment of a connection device 1. Fig. 8a-c show another embodiment. The connection device 1 is designed for connecting a flat cable 50 (see also fig. 5 and 8a for this purpose), which generally has a plurality of conductors 51, which are preferably each surrounded by an insulating layer 52 and embedded in an overlying cable sheath 53.

The flat cable 50 has a main direction of development X and extends in a plane X-Y. The flat cable is terminated in the Z-direction by a termination device. The X-Y plane is oriented horizontally in the exemplary application position in fig. 1. At this time, the Z direction is a vertical direction. The concepts employed below, such as up, down, right, left, etc., all refer to the assembled position of fig. 1 in which the wiring device is placed on a horizontally oriented base, not shown. The concepts described in the further assembly positions on the vertical wall or the like are correspondingly modified or the like, so that the situation other than the assembly positions should therefore not be understood as limiting.

The connection device 1 is used in particular for connecting flat cables in building shaft structures, for example elevator shafts. The wiring device has a one-piece or multi-piece base housing 2 (fig. 3, 8a) with a base portion 3 and a cover portion 4. In a preferred embodiment, the base part 3 is configured as a substantially rectangular floor 3. The base plate 3 may have, for example, in the region of one or more corners thereof, fixing regions 5, on which the base can be mounted on a foundation, such as a wall. For this purpose, the fastening regions 5 can have, for example, fastening holes, on which the base plate 3 can be fastened to the foundation by means of fastening elements (not shown here), for example screws. The cover part 4 can for example be snapped or otherwise fixed to the base part 3. The

parts

3 and 4 are integrally formed or connected as described in connection with fig.8 a-c.

The base plate 3 extends parallel to the plane of the flat cable 50 to be terminated. The base plate also has lateral strips 6 which project parallel to one another upward from the plane of the base plate 3 on the upper side facing away from the lower fastening side.

A contact plate unit (fig. 1, 2) can be placed or can be supported on the base plate 3. The contact plate unit according to fig. 1, 2 and 6 is designed as a first type of construction as a printed circuit board unit 7. The circuit board unit 7 has at least one circuit board 8, which can be mounted directly on the base plate 3 or can be arranged thereon. A plurality of insulation-penetrating contacts 9 (also referred to as insulation-penetrating contacts), preferably soldered on the circuit board, are arranged on the circuit board 8, which preferably project vertically upwards from the circuit board 8. The contacts 9 penetrating the insulating layer are each designed as fork contacts with a cutting edge which narrows towards their free ends. Each fork contact is designed as an insulating layer for the partial cutting of the conductor and rests against the conductor exposed therefrom in order to connect the conductor.

In the region of the contacts 9 penetrating the insulating layer, a shield 11 is mounted on the circuit board 8, the area of the shield being smaller than the circuit board 8. The cover plate 11 has an opening, in particular a slot 12, which at least partially penetrates the cover plate 11. As can be seen in the exemplary loaded conductor board arrangement of fig. 6, the insulation-piercing contacts 9 are preferably advantageously supported downward in the openings 12, so that the cover plate 11 forms a support when switched on. The actual contacting of the printed circuit board 8 takes place laterally to the bearing region, preferably laterally to the slot 12 of the cover plate 11 (not visible here).

In this respect, the cover 11 serves to support and stabilize the insulation-penetrating contacts 9 and to protect the printed circuit board 8 (not shown in fig. 6) when the flat cable is pressed into the conductors 51. A preferred form of the contact structure here penetrating the insulating layer is explained in detail below with reference to fig. 10 and 11.

In addition, one or more termination contacts, such as socket or

latch plates

13, 14, can be provided on the circuit board 8, to which termination contacts electrical/electronic component wire ends or plugs or similar structures, not shown here, can be connected. The connection direction Y-Y of the socket and/or

latch plates

13, 14 is preferably always oriented partially perpendicular to the main direction of extension X of the flat cable. The connection direction can also be oriented completely or partially in the direction of alignment or main extension of the flat cable. In this case, the connection can be made via corresponding pin/blade and socket contacts, which preferably make a direct electrically conductive connection between the connecting devices arranged one above the other (not shown here). These socket boards and latch boards or other terminals are preferably accessible from the outside between the base plate 3 and the cover part 4.

A cover part 4 (fig. 1) can be placed or placed on the base part 3 with the circuit board unit 7. The covering part 4 has a lower frame part 15 from which two

slats

16, 17 extend laterally and vertically upwards. The cover part 4 is thus substantially U-shaped in a view in the Y-Z plane (fig. 2).

In the region between the

parallel strips

16, 17, a receiving space, here rectangular, is formed, into which the cable support plate 18 can be inserted. The cable support plate 18 serves to support the actual flat cable 50. The cable support plates can have grooves 19 which are parallel to one another, so that the cable support plates can be well adapted to the correspondingly shaped flat cable 50, whereby the conductors of the flat cable lie securely parallel to one another on the cable support plate 18. In addition, the cable support plate 18 has openings, in particular slots 20, which are passed through it and which, in the switched-on state, are passed through by the free ends of the contacts 9 which penetrate the insulating layer.

The cable support plate 18 is guided on the guide grooves 21 of the

strips

16, 17 of the cover part 4 so as to be movable perpendicular to the plane of the flat cable 50 but not parallel to its plane (X-Y plane). The cable support plate may also have snap hooks 55 (fig. 2, 8a) or similar structures on two or more sides, in particular on three sides. The cable support plate 18 is locked with the snap hooks in the contour (see, for example, edge 66) of the housing 4 (not shown in detail here). This is preferably achieved in such a way that the cable support plate 18 remains somewhat movable in the Z-direction relative to the housing 2.

The cable support plate 18 is advantageously also resiliently supported on the frame part 15 of the cover part 4 of the housing 2 with one or more springs 54. These springs 54 are here constructed as helical springs in the preferred embodiment. It is contemplated that other configurations of springs may be used. These springs may also be configured as one or more resilient segments (not shown) on the housing 2 and/or on the cable support plate 18. Advantageously, the cable support plate 18 is prestressed against the switching direction (Z) by means of a spring, which helps to ensure a precise switching operation.

The

slats

16, 17 are here of a triangular shape in the view of the X-Z plane and project from the frame part 15 in the Z direction, so that at least one or more (here many not shown) eccentric units 22 can be arranged, moved and stored.

Two different types of construction of the eccentric unit are considered below (fig. 4, fig. 7). Each eccentric unit 22 has a substantially cylindrical eccentric roller 23 which has lateral bearing journals 24 of smaller diameter on its axial sides for supporting the eccentric roller 23.

The bearing journal 24 is arranged eccentrically to the imaginary center axis M of the eccentric roller. The eccentric roller 23 preferably has at least one flattened area 25 (see fig. 8a-e) on its outer circumference. In addition, the eccentric roller 23 is provided with a radially extending slit 26, which preferably extends a distance into the eccentric roller 23 from the outer diameter through the centre axis M. The slot 26 serves as a working contour for the operating tool, here a screwdriver.

The eccentric roller 23 is inserted laterally into an integrated or multi-part eccentric housing 27 of the eccentric unit 22 and is rotatably mounted therein. The eccentric housing 27 here has a basic shape which is rectangular in the X-Y plane. The eccentric housing is designed to sink into the frame part 15 of the cover part 4 (in its opening 28, see fig. 2).

According to the first type of construction according to fig. 4, the eccentric housing 27 surrounds the eccentric roller 23 almost completely. The eccentric housing preferably has a window 31 on its side facing away from the base part, which is configured such that the operating tool can introduce the working contour (here the slot 26) and the eccentric roller 23 can be pivoted by the required extent for the wiring.

In addition, the eccentric housing 27 has a section, in particular one (or two mutually parallel) side walls 29, in which a vertically (in the Z direction) extending slot 30 (fig. 4) or slot 30a is formed. The bearing journal 24 of the eccentric roller 23 passes through the slot or slit.

The eccentric roller 23 is arranged in the eccentric housing 27 so as to be rotationally movable. The eccentric housing 27 has a pressing side 27a in the direction of the contact 29 penetrating the insulation layer.

The width of the eccentric housing 27 in the Y-direction (spacing of the side walls 29) is equal to the distance Y1 (see fig. 3) between the

slats

16, 17 of the cover part 4. In addition, a receiving contour 32 is formed in each of the

webs

16, 17 of the cover part 4, which contour makes it possible to introduce the bearing journal 24 of the eccentric unit 22. The receiving contour 32 is preferably designed such that the eccentric housing 27 can be introduced with a movement component in the X direction until it rests against the stop 33 in the X direction, which is clearly perceptible when the eccentric unit 22 is introduced.

In addition, each receiving contour 32 of the cover part 4 advantageously has, preferably upwards, a vertical stop contour 34 in the direction facing away from the base plate, which is preferably rounded (for example in the form of a semi-cylindrical free space) and forms a stop in the form of a seat and a base for the bearing journal 24 counter to the switching-on direction Y. The bearing journal 24 of the eccentric shaft 23 can also be configured as an end of a continuous shaft (not shown here).

The pressure heads 27a of the eccentric housing 27 of the eccentric unit 22 each have, in their mounted state on the cover part 4 of the housing 2, one or more projections 35 on the underside of the flat cable 50, at least in the region or regions where the flat cable is to be pressed against the insulation-piercing contacts 9 and into which the flat cable is cut by the contacts, as an abutment for the contacts on the pressure side 27 a. This advantageously makes it possible to apply the wiring force in a targeted or more precise "punctiform" manner exactly in the region in which the flat cable 50 is to be connected (fig. 8 a).

The function of the connection device with the eccentric unit 22 described above in terms of its construction when connecting flat cables is as follows.

In addition to the eccentric unit 22, the housing 2 of the preassembled wiring device 1 is preassembled (see fig. 3), placed on a mounting base and preferably fixedly mounted thereon (for example, the housing is screwed to the mounting base, not shown here).

The flat cable 50 is now placed between the

strips

16 and 17 on the cable support plate 18, which is urged upwardly by the spring 54. The eccentric unit 22 is then introduced with a parallel component of movement of the flat cable into the space between the

strips

16 and 17, so that the bearing journal 24 engages in the receiving contour 32. This moves the eccentric unit 22 up to the stop 33 of the receiving contour 32. In contrast to the illustration in fig. 1, the bearing journal 24 is in the lower position in the elongated hole 30 (or in the slot 30a, see fig. 9 b). The eccentric roller 23 is then rotated from the outside with the operating tool (compare the position of the gap 26 in fig.8a, 8b, 8 c). This applies a pressure force in the wiring direction (Z) on the inside of the lower side or side wall 27a of the eccentric housing 27, which pressure force moves the eccentric housing 27 with the pressure side or side wall 27a and its projection 35 in the direction of the contact 9 penetrating the insulating layer.

Further pivoting of the eccentric roller 23 continues to push the pressure side 27a perpendicularly to the flat cable 50 in the direction of the flat cable (Z direction, fig. 8b), since the bearing journal 24 is supported and fixed in the cover part 4 in the Z direction in a seated manner upwardly on the contour 34. Once the underside 27a (with the projections 35 here) reaches the flat cable 50, the flat cable 50 is pressed against the free ends of the insulation-piercing contacts.

The pivoting is continued until the flat cable 50 is pressed against the insulation-piercing contact 9 to such an extent that the contact pierces through the cable jacket 53 and the insulation 52 and reliably connects the one or more conductors 51 to be connected (fig. 8c, 9 c). This position can advantageously be felt here when the flattened region 25 of the eccentric roller 23 is reached, which increases the reliability during the wiring (fig. 9 c). In this way, the wiring requires only a small force and can be performed manually in a simple and problem-free manner. The flattened area furthermore ensures that a defined position is achieved in the form of a "snap-in" and thus prevents the eccentric roller from rotating.

In the first exemplary embodiment of the eccentric unit 22 of fig. 4a) to e), the latching in the first position is effected in a very simple manner before the connection and after the wiring or connection by means of small projections 67, which engage in two positions in a snap-in manner in

small openings

68, 69 in the side wall 30 of the eccentric housing 27 with the elongated hole 30 before and after the connection (fig. 4b) to d)), respectively. This simplifies the switching-on process and keeps the eccentric roller 23 in the respectively reached position.

In the second embodiment of the eccentric unit 22 according to fig. 7, the eccentric housing 27 is open on the other side, 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 two slots 30a which open upwards and through which the bearing pin 24 passes after the installation of the eccentric roller. In the lower region, the slot can have a constriction 36 (fig. 9b), so that the bearing pin 24 can be engaged in the slot 30a in the lower installation position, from which it is moved into the switched-on position.

The pre-mounted eccentric housing 27 is used to connect the flat cable 50 exactly as the eccentric housing described above. If the eccentric roller 23 is pivoted, its outer circumference is pressed again against the housing wall 27a in the direction of the insulation-penetrating contact, which is moved forward in the direction of the insulation-penetrating contact 9 until the flat cable is pressed against the insulation-penetrating contact 9 to such an extent that the contact reliably connects the conductor to be contacted.

The contacts 9 penetrating the insulating layer may be, but need not be, mounted on the circuit board unit 7. The contacts may also be mounted on another contact plate unit in advance.

The mounting base can be configured, for example, as a contact receptacle plate 8 '(see fig.8a) in which blind-hole-like or stepped holes or slots 37 are arranged, so that the contacts are thereby arranged and supported in the contact receptacle plate 8' with a base portion 40. This base portion 40 may also be part of the terminal.

In the case of the connection device according to fig. 1 to 6, the contact receptacle plate is designed as a circuit board. In contrast, according to a further variant of the connection device according to fig.8a) to e), the contact receptacle plate is not a circuit board, but rather is provided with terminal contacts 72 for connecting conductor ends 75 or the like, which are electrically conductively connected to or formed with the insulation-penetrating contacts 9. The termination contacts 72 are preferably accessible from the back of the housing 2 (fig. 8b, c). According to fig.8, the base part 2 and the cover part 4 are integrally formed, i.e. the housing 2 is one-piece, which is possible due to other configurations of the contact-receiving plate that will be explained further on. However, according to the solutions of fig. 7 and 8, the actual contacting of the flat cable is designed similarly or even identically to that of fig. 1 to 6.

According to fig.8a) to e) and f), the contact receptacle plate 8 is preferably also provided with openings 68 in the region of the slot or opening 37, starting from the opposite side. A wire may be introduced into one of these openings 68. The other opening 68 is here configured for the introduction of an operating tool.

The opening 68 is arranged to open into a contact chamber 71 for a terminating contact 72 for a wire end 75 or the like of a wire 76 (fig. 8 c). The contact chamber 71 is formed by the opening 37. The contacts 9 penetrating the insulating layer are supported in the contact cavities 71 during wiring. The termination contacts 72 may be configured as spring contacts or as spiral contacts or the like. In the present case, the terminal contacts are embodied as pressure spring contacts In direct plug technology (Push-In plug-In). The openings 68 are preferably accessible from the back of the enclosure (see fig.8a), b), and c). In this case, no connection terminals are required on the side faces (cover plates 13, 14). The wires are preferably led out through a recess or opening 74 in the housing 2 (fig. 8a, b, c).

In the direction of the eccentric unit 22, a cover 38 (here with a snap-in strip 73) can be placed on the contact receiving plate/contact receiving surface 8', which cover itself has the same small opening as the contact receiving plate 8', in particular a slot 39, from which the free end of the insulation-piercing contact with the cut-out edge projects outwards in the direction of the eccentric unit 22. This also reliably guides and holds the contacts 9 penetrating the insulating layer. Preferably, an electrically conductive connection extends from the base part 40 of the insulation-piercing contact 9 to at least one external terminal or plug terminal 13, 14, respectively.

If a circuit board arrangement 7 with a circuit board 8 is used as the contact board arrangement (fig. 1 to 6), it is particularly advantageous if the contacts 9 penetrating the insulating layer are then arranged on the circuit board arrangement 7. Each insulation-piercing contact 9 has its own contact cutting, to which is in turn connected a base part 41 on the side facing away from the insulation-piercing contact tip, which base part is inserted into an opening 12 of a cover plate 11 on the printed circuit board 7. If a force is applied to the free end of the contact 9 penetrating the insulating layer, the contact is thus reliably supported on the cover plate 11 as a support. In this way, the forces exerted on the insulation-penetrating contacts 9 during the wiring process, each in the form of a point, are introduced into the printed circuit board 8 via the cover plate 11 in a surface-distributed manner, which simply protects the printed circuit board from excessive loads that could lead to damage (fig. 10). Alternatively, the cover plate 11 can also be supported on the base part 3 of the housing by means of strips 42 which pass through the printed circuit board 8 (fig. 11) in order to keep the printed circuit board 8 nearly completely free of wiring forces.

The actual connection of the printed circuit board 8 is effected by an electrically conductive connection, for example a busbar section 43, which is oriented on the base part 41 at an angle, in particular at right angles, to the wiring direction and is preferably soldered on or in the printed circuit board 8 via a pin section 65 which passes through the cover plate 11 and is again oriented at an angle to the busbar section 43. Such a "soldering site" is preferably spaced apart from the cut edge of the insulation-piercing contact 9 perpendicularly to the wiring direction (-Z). The busbar section 43 can also be U-shaped and then merges into the pin section 65. The U-shaped busbar section 43 can thus be easily elastically deformed in the Z-direction.

Advantageously, the plurality of terminal devices are arranged next to one another in the main direction of extension of the flat cable. For this purpose, corresponding positive-locking structures are preferably formed on the sides of the housings 2 of two adjacently arranged connecting devices 1 facing each other, so that the connecting devices 1 are held together in a positive-locking manner. For example, one or more corresponding grooves 44 and tongues 45 (see fig. 1, for example) can be formed in the housing, in particular in the strip, in the main extension direction, which together form a dovetail connection.

As mentioned above, in some applications it is necessary to connect one or more conductors of the flat cable 50 at two more positions offset in the main direction of extension. In addition, it is often necessary in this case to interrupt the conductors between these two positions in which the conductors of the flat cable are connected. This can be done with pliers or similar tools, using pliers to punch a hole in the wire. But it is simpler to adopt the following arrangement (see fig. 12 to 14).

In order to contact the flat cable 50 at a distance, two contacting devices are provided on the flat cable, which are offset in the main direction of extension X of the flat cable.

According to a further development, a punching device 46 with a housing 47 and a punching structure for punching one or more wires is provided on one or between two contact devices 1, which can also be regarded as a separate invention and can also be used, for example, in a wiring pattern for the IDC contacts 9 other than an eccentric roller operation.

Form-locking structures, in particular the tongue 44 and the tongue 45, are formed on the housing 47 of the punch 46, which correspond to the form-locking structures of the connector housing 2. In this way, the housing 46 can be arranged in a form-locking manner on two connecting devices 1 adjacent to the housing; 1 between the

shells

2, 2. This arrangement is simple and advantageous.

The housing 47 of the punching device 46 has a lower housing part 48 (fig. 14c) and an upper housing part 49 (fig. 14a, b). The lower housing portion 48 is preferably U-shaped in an X-Z view. The housing lower part 48 makes it possible to accommodate a flat cable 50 which can be inserted between two

webs

57, 58 extending in the Z direction and held centrally. The support region 59 of the lower part of the housing has a recess 60 below the region where the flat cable is to be cut.

The upper portion of the housing has one or more openings 61 oriented perpendicular to the flat cable and radially flush with the flat cable. The opening 61 is above the depression in the Z-direction. If a punch 62 as a punching structure is pushed into each opening 61, for example, the knock-in opening 61, the wire 51 under the opening 61 is cut. This type of interruption of the circuit can be implemented simply and reliably. Since the punch is a structurally separate unit from the connecting device, the punch only has to be used in this application, otherwise it can be dispensed with. The upper housing portion 49 may be secured to the lower housing portion 48, such as with a snap-fit arrangement. The latching arrangement here comprises, by way of example, two preferably releasable latching hooks 63, which are designed for latching onto corresponding latching contours 64 of the housing lower part 48. This makes it possible to interrupt the conductors of the flat cable simply and precisely. Such an operation is advantageously simple, but still achieves very accurate results. The opening can also be closed first and opened in a pretreated form by breaking open, for example by injection-molded projections. The fitter then knows exactly at the site of use where the punch should be introduced.

Fig. 15 shows a third variant of a connection device 1 for connecting flat cables in a) to e), which can be arranged in particular in a shaft-like structure, preferably in an elevator shaft. The connection device also has a two-part base housing 2 (fig. 3, 8a) here, which has a base part 3 and a cover part 4, which are integrally connected or snap-connected or connected in another way. Furthermore, a bottom cover plate 3' is provided, which prevents dust from entering from below. The wiring device 1 is configured in the same manner as the wiring device of fig. 8. Therefore, only the differences of the scheme of fig.8 are explained below. Therefore, this solution also has a second embodiment of the eccentric unit 22 of fig. 7 (see fig. 15 b). In contrast to fig.8, however, more contacts 9, which are also designed as IDC contacts, are arranged in three parallel rows, which are used to connect the conductors or cores of the flat cable 50. Correspondingly, more contacts 72 for the terminals of the conductors are provided, which are each provided for connection to a conductor of the flat cable 50.

The connection device of fig. 15 also has a cover cap 77, which covers the eccentric unit 22 from above, thus protecting the eccentric unit well. This is particularly good at avoiding the entry of dust, which can contaminate the eccentric unit placed in the elevator shaft. The cover cap 77 is preferably fastened directly to the eccentric unit 22 and extends in the mounted position of the base housing 2 preferably between the

slats

16, 17. The width of the covering hood 77 in the Y direction therefore preferably corresponds to the distance Y1 between the

strips

16, 17 of the covering part 4 (see fig. 3). The cover cap 77 is preferably fixed to the eccentric unit 22 in a form-fitting and/or snap-in manner. In addition, the eccentric housing can also have supporting profiles 27b which run obliquely and serve to stabilize and support the covering cap 77. The cover cap 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. Furthermore, before the mounting of the eccentric unit, one or more elements of the eccentric unit, such as its eccentric roller 23, are also fixed to the cover cap in order to prevent falling.

A tension relief contour 78 is molded on the base housing 2, here on its cover part 4, which contour projects in the main extension direction (fig. 15d) of the flat cable 50 to be connected. On the tension relief profile 78, here in the form of a partial flange (Teilkragen), a cable harness (not shown here) can be fixed. Corresponding partial flanges 78 'can be formed on the bottom cover plate 3'. The partial flange 78 and the partial flange 78' are limitedly movable relative to each other perpendicular to the main extension direction of the flat cable 50. The flat cable 50 can be simply clamped and fixed by means of the cable harness, guided by the partial flanges 78 and 78'. This makes it possible to easily relieve the tension of the flat cable 50.

The cover cap 77 and the tension relief contour 78 for the tension relief allow all the shown embodiments of the invention to be realized.

One or more strips 79 are provided on the cable support plate 18. The slats 79 are preferably detachably secured. The slats extend in a direction perpendicular to the plane of the cable support plate 18. The strip is located at a position where one or more core wires of the flat cable are interrupted, for example by a punching device, in order to enable a safety circuit function, for example.

The bottom cover 3' preferably extends only over the width of the flat cable 50 to be connected or at least over said width (fig. 16 d). According to the embodiment of the connection device of fig. 15, no electronics for processing signals, in particular no electronics printed circuit board, is provided on the connection device.

The problem of supplementing the connection device with electronics for processing signals, in particular electronics circuit boards, according to the solution of the type in fig. 15 is solved by providing an electronics housing with electronics, in particular electronics circuit boards, which can be placed on the base housing 2 and can be fastened thereto and which has the electronics.

This arrangement is realized in fig. 16a) to d). An electronics housing 81 with electronics, in particular an electronics circuit board 82, is provided, which is mounted on the base housing 2 in the main direction of extension of the flat cable 50 to be connected and is fixed thereto. One or more circuit board pins 83, 84 are formed on the electronic circuit board. They allow for the connection of cables 85 or wires.

According to the illustrated embodiment, the terminal contacts 77 of the connection device 1 are connected to wires, which in turn connect the conductors or wires of the flat cable 50, which are connected to the corresponding contacts 9 of the connection device 1, to the electronics circuit board 82 via one of the circuit board plugs 83. The cable 85 is connected as an output or input to another circuit board plug 84.

In the preferred embodiment, the electronics housing 81 is configured to be relatively flat and elongated and is configured to be significantly flatter, perpendicular to the direction of the flat cable, than the base housing 2 of the wiring lug 1. The electronics enclosure may have a cover 86 to facilitate connection of wires and/or cables and/or plugs.

Preferably, but not necessarily, the electronics housing 81 is simply snap-fitted on the base housing 2. For this purpose, the electronics housing is preferably moved (arrow P) in the main extension direction of the flat cable 50 and is fixedly clipped to the base housing 2, for which purpose the electronics housing has corresponding clipping structures (only one of said clipping structures: 87 is visible here).

The electronics housing 81 may also be secured below, above, or on another side of the base housing. The solution of fig. 16 is particularly advantageous because the electronics housing 81 is compactly positioned adjacent to the flat cable 50. Corresponding plug-in connectors (not shown here) which can be plugged together can also be provided directly between the electronics housing 81 and the base housing 2.
