Description

The invention relates to a method for wiring of connection points of electrical devices or assembly elements and one in particular for performing this method installed pipe laying equipment.

From DE 42 18 741 A1 (corresponding to US Pat. No. 5,515 606 and EP 0 573 791 A1) is a method for wiring of connection points of electrical devices or assembly units known that is with a high degree of rationalization through operational safety and extensive avoidance characterized by possible errors. The procedure is generally applicable and in particular also for wiring usable by electric lights. It ensures one rational complete automation of the wiring electrical devices and assembly elements and allows on pre-assembled cables and partial or full cable harnesses to do without because there is a direct assembly of the lines in the device or the component element.

The process is controlled with the help of mechanical Cable laying equipment carried out in such a way that initially a pre-assembled electrical device or Module element with fixed connection points provided and then by a relative movement between the pre-assembled device or assembly element and the line laying means a first connection point brought into the work area of the pipe laying equipment and is positioned correctly in relation to these. By means of the line laying means the end of this one endlessly fed line into a contact zone of the first connection point introduced and under production an electrical contact fixed at this junction. Through a further relative movement along each a predetermined path between the pre-assembled electrical Device or assembly element and the cable laying means is successively laying the line every further connection point in the work area of the cable laying equipment brought and relative to these in the correct position positioned. Give during these relative movements the line laying means at least one of the line laying route between the two respective connection points Length of the line fed to them endlessly. The endlessly fed line is from the line laying means at each junction in a contact zone introduced and producing an electrical contact fixed to this junction, which means that at through-wiring takes place at these connection points.

The line laid in this way is then at the end of the line laying route in the area of the corresponding junction cut off. The cut off At the same time, the end of the cable is touch-proof at the connection point secures. The one to carry out this procedure Cable laying equipment used have a laying tool on that protruding with a on a case arranged laying finger is formed, in which a cable duct is included and the controlled feed means assigned to the line. The laying tool is, for example, by an industrial robot on a preprogrammed cable routing moves and on each positioned to be contacted. The Contacting zone of this connection point is with a Insulation displacement contact formed in the insulation displacement slot the line to be contacted from the line laying tool is pushed in.

For this is on the laying tool near the mouth of the cable routing channel essentially across the axial direction of the guide channel, in the mouth area movably mounted and coupled with its own adjusting means Pressure member provided that with respect to the mouth of the Cable routing channel between a distant from the mouth remote rest position and a working position is adjustable, with one on the out of the mouth protruding line aligned printing area the Mouth edge of the guide channel protrudes on one side or essentially with the top of the muzzle flees.

There is still between the pressure member and the laying finger a separately controllable knife blade available with the opening edge of the guide channel serving as counter knife interacting at the last junction of the line routing can cut the line.

The connection points are designed in such a way that they each contain the contacting zone comprise having a housing made of insulating material at least one edge-open insertion slot for a line and at least one disposed in the housing Insulation displacement contact with an aligned on the insertion slot cutting clamp slot open to the edge exhibit. The insulation displacement contact is surrounding it Housing parts added safe to touch.

In the housing is on at least one side, subsequently to the insertion slot, a line receiving Extension in the form of a slot or groove-like Well available, the width of which is greater than the width of the Insertion slot and its dimensions are dimensioned in this way are that in the vicinity of the insulation displacement contact free end one in the insulation displacement contact Contacted cable in a contact-safe manner in this slot or groove-like extension can be added.

At the same time, the slot or groove-like extension, just like the housing to the dimensions of the laying finger and the pressure member of the laying tool of the line laying means matched so they double Can perform the task:

On the one hand, it takes on the last junction of the The cut end of the cable is protected against accidental contact so that its bare conductor end for the standardized test finger is not accessible from the outside; on the other hand, it acts as a guide for the Laying finger of the laying tool when positioning the Laying tool over the connection point and when pressing in the line into the insulation displacement slot of the insulation displacement contact through the pressure member.

This latter function of the slot-like or groove-like Extension or deepening at the junction but requires a certain minimum width of the deepening, the is considerably larger than the diameter of the insulation the contacted line. The reason is that the Laying fingers dipping into the recess around both sides of its cable duct wall parts is thicker than the outer diameter of the conductor insulation the electrical line contained in the guide channel, this thickness measure additionally by the for a slight advancement of the line in the guide channel required oversize whose diameter is increased.

This considerably increases the outside diameter of the conductor insulation exceeding width of the slot or groove-like Deepening the housing at each connection point means that in the case of multi-pole terminals, the distance between adjacent Connection points a certain minimum dimension can fall below, due to the width of the laying finger and respectfully between the connection points wall thicknesses required for the air and creepage distances is specified.

However, there are use cases where it is, for example Adjacent connection points are necessary for reasons of space move closer together or the individual connection points to make it narrower than this in consideration of the slot or groove-like depression or extension of the Housing immersed laying finger was possible. Because now in practice it must be expected that in a Device both connection points of the known known Kind with width matched to the thickness of the laying finger the slot or groove-like depression in the housing as well narrower connection points must be used, the possibility remain guaranteed regardless of the special Design of the connection points in one work step fully automatically without changing tools or the like wire.

This results in the basis of the invention Task, namely the wiring method mentioned at the beginning to develop in such a way that it is also automatic Wiring of connection points allowed, their dimensions regardless of the laying finger only in With regard to the clearances and creepage distances to be observed are selected, but at the same time the Contacting at the contact points designed in a known manner remains possible in the same way. Also wants the invention a suitable for performing this method Create laying materials.

To achieve this object, the invention Process the features of claim 1 while the line laying means according to the invention by the features of claim 7 are characterized.

The laying finger remains with the new cable laying method when contacting the line outside the Housing parts determining the external dimensions of the connection point the connecting clamp. The dimensions of the housing parts can therefore be completely independent of the laying finger be selected as this for the needs of the respective application, taking into account the necessary Clearances and creepage distances are necessary. Nevertheless the line remains in perfect contact the respective connection point, as well as none Slowdown or obstruction of automatic You have to put up with the wiring yourself. At connection points, which in the known way with one on the dimensions of the laying finger matched slot or groove-like Are provided, the wiring is done in the usual way without any Changes would be necessary.

The new line installation means itself is compact in its structure and easy to control, i.e. it does not require additional measures on the one serving to move it Industrial robot or portal. The line is working properly into the insulation displacement slot of the insulation displacement contact indented, with a guide of both the pressure member and thus also the line laying means as well as - if necessary - a pre-fixation and positioning of the line when inserting into the insertion slot of the connection point possible are.

To the further state of the art of cable laying equipment reference is made to DE-AS 1 290 210, US Pat. No. 3 930 525 and U.S. Patent 4,703,543 and DE 43 12 777 A1 just to mention a few examples. All these Pipe laying equipment is not used to carry out the method set up according to the invention. Interchanges, whose contact zones contain insulation displacement contacts, are also known in various forms. As An example of this is DE 32 36 868 A1, whose connection points a safe touch safe custody of a Allow the wire end to be cut off, but overall this way are designed so that they do not fit into a grid.

Advantageous further developments of the new method and of the new line installation means are the subject of subclaims.

The method of direct wiring electrical Devices and assembly elements can advantageously be used for Wiring of lights can be used like this in the DE 42 18 741 A1 is explained. It is from a pre-assembled Luminaire box from which to operate the Electrical discharge elements required for gas discharge lamps contains the correct position according to a given site plan are firmly attached to the bottom of the box and from only an electrical ballast in FIGS 1, which is illustrated with the invention designed connection points is formed. These junctions 2 are all based on the same basic principle with a contact zone according to the insulation displacement technique designed. Their training is exemplary in detail 2 to 5 can be seen from which the principle to be explained:

Each connection point 2 is in an insulating material (Plastic) existing housing 4 of a clamping means, For example, a connecting terminal, formed, the single pole or, as shown in FIG. 2, bipolar or else can be multi-pole, as shown in FIG. 3. The insulating housing 4 is essentially cuboid in FIG. 2 and below with a fastener in shape provided a bracket 5 with which it is on a bent up cut out tab 6 a base plate 7 of the ballast 1 is attached.

On a box-shaped indicated in Fig. 4 at 8 Base wedge of the housing 4 are at equal intervals parallel, vertical walls 9, 10 formed, each limit a contact zone 3 (Fig. 5) laterally. In Each contacting zone is a metallic insulation displacement contact 11 transverse to the longitudinal extent of the walls 9, 10 arranged arranged in a known manner Insulation displacement slot 12, which to the Line insertion side opens, the top in Fig. 2 of the housing 4. The one not shown in Way with the winding of the ballast 1 electrically Conductively connected lamellar or tab-shaped IDC contact 11 is at its opposite Narrow sides in parallel grooves 13 in the associated Walls 9, 10 added with play, such that the IDC slot 12 delimiting leg of the IDC contact 11 when pressing in to be contacted Dodge line elastically.

Both sides of the insulation displacement contact 11 are connected to the both side walls 9, 10 rib-like or strip-like inside Projections 14 are formed, each in pairs opposite each other and each have a cable entry slot 15 limit, the open to the entry side and has a substantially U-shaped shape. The rib-like or strip-like projections 14 are in Seen longitudinal direction of the walls 9, 10, at a distance from that Insulation displacement contact 11; they also form the side Limitation of the contact zone 3, which is thus in a Chamber of substantially rectangular cross-sectional shape is included. At the two insertion slots 15 each junction 2 close on both sides two slot-like or groove-like depressions, the extensions the insertion slots 15 form and to the Front or rear of the housing 4 and to the cable entry side open up. The slot-like or groove-like Extensions 16, the insertion slots 15 and the IDC slot 12 are each in a common Plane of symmetry, which is indicated in Fig. 5 at 17. The Depth of extensions 16 is in this embodiment slightly larger than that of the insertion slots 15, which, 3 and 4, essentially is equal to the depth of the insulation displacement slots 12.

However, embodiments are also conceivable for which the extensions 16 the same depth as that Have insertion slots 15 and the insulation displacement slots 12, i.e. that the bottom wall 18 of the respective extension 16 with the lower edge 19 of the insulation displacement slot 12 is essentially aligned, as shown in FIG. 13 is illustrated. This ensures that the in the Insulation displacement slot 12 indented contacted line on both sides of the insulation displacement contact 11 on the bottom of the slot or groove-like depressions or extensions 16 rests. This results in security against one possible overpressing or cutting the line in the Bottom of the cutting contact slot 12 while at the same time the overall height of the entire terminal at the connection point can be reduced.

To insert the cable into the insertion slots 15 to facilitate the walls 9, 10 in the area of rib-like or strip-like projections 14 with inward pointing insertion bevels 19, which correspond Insertion bevels 19a on the adjacent ones Are assigned to wall areas (cf. Fig. 2).

The length, depth and width of each of the slit or groove-like extensions 16 is chosen so that the end one in the insulation displacement slot, for example in accordance with FIG. 21 12 of the insulation displacement contact 11 of the respective Junction contacted line 20 in the extension 16 is kept safe from touch. It means that the "standard test finger" when testing for touch safety not up to the free bare end of the in the Close to the insulation displacement contact 11 cut line 20 can penetrate. Here is the width of the depressions 16 on the outer diameter of the insulation to be contacted Line 20 tuned; it is, as for example Fig. 21, 22 show only slightly larger than this outer diameter, but can also be the same or even be slightly smaller than this outer diameter. The Width of the insertion slots 15 is in any case such that they somewhat smaller or at most essentially the same Outside diameter of the insulation to be contacted Line 20 is so that they are elastically compressed Isolation held and thus strain relieved or but is at least guided sideways.

The adjacent connection points 2, i.e. the lateral distance between the centers of adjacent insulation displacement slots is achieved by minimizing the wall thickness Side walls 9, 10, the cutting contact width, the width of the click or groove-like extensions 16, etc. one small predetermined latching distance of e.g. 3.5 mm accordingly educated. The whole connection point corresponds to their latitude, longitude and, if necessary, also in their depth dimension a predetermined grid dimension, the minimum size due to the requirements of at least clearances and creepage distances to be observed.

The slit or groove-like depressions or reductions 16 can at their of the insulation displacement contact 11 remote end each to the Recess-delimiting walls 9, 10 molded onto one another have opposite rib-like projections 22, as this is illustrated, for example, in FIGS. 8, 14 and 17 to 19 is. These opposed to each other in pairs limit rib-like or strip-like projections 22 in each case towards the insertion side, open-edge receiving slots 23 for line 20, which on the inlet side with provided on the outside to widen insertion chamfers 19 are and their width is usually smaller or at most equal to the outer diameter of the insulation to be contacted Line 20 is dimensioned. That way the contacted line 20 also on this from the insertion slot 15 distant point held tensile, where at the same time an outer closure of the recess 16 inserted line is reached.

Otherwise, the insertion and the receiving slots need 15, 23 not have a constant width over their depth. It is often convenient to use the rib-like or strip-like Place projections 14 and 22 over the groove depth, such that, for example, in the vicinity of the groove bottom a smaller width and thus a stronger clamping for the pressed line. This area decreased Width is for the insertion slots 15 in the 3 at 15a. Both Embodiments according to FIGS. 6, 12 and 15 are the Areas of reduced slot width in the receiving slots 23 between opposite pairs Retention lugs 24 present. The retention lugs 24 are on the rib-like or strip-like projections 22 in Molded on distance from the slot bottom; they have one tapered profile shape towards the slot floor on and are formed with retention shoulders 25, which an unintentional release of one in the respective Prevent receiving slot from pressed line 20. Appropriate measures can also be taken on the insertion slots 15 delimiting rib-like or strip-like Projections 14 may be provided. Otherwise extend the rib-like or strip-like projections 14 and 22 the air and Creepage distances so that they further minimize the Dimensions of the connection point when fitting into the Allow grid size.

In order to achieve sufficient stability despite this minimization and clamping action of the insulation displacement contacts 11 ensure it can be useful with very small dimensions be, the insulation displacement contacts 11 no longer, as in Fig. 5, 19 shown as a simple flat leaflet train, but profiled in cross section shape. Examples of this are shown in FIGS. 17, 18 illustrated. 17 in the embodiment of FIG the insulation displacement contact 11a in cross section U-shaped and in the contact zone 3 on one side by molded Ribs 26 on the side walls 9, 10 of the junction of an axial direction while the fixation in the other axial direction through the rib-like or strip-like Projections 14 of the insertion slot 15 happens.

In the embodiment according to FIG. 18, the insulation displacement contact is 11b S-shaped in cross section. He is supported in the axial direction of the extensions 16 on both sides of the delimiting the insertion slots 15 rib-like or strip-like projections 14.

Depending on the purpose of the respective connection point 2, embodiments are also conceivable for which are adjacent to the insulation displacement contact 11 Insertion slot 15 only on one side to the Slit or groove-like extension leading outside the housing 16 connects. The one described below Wiring procedures also allow the connection points to train so that one of the groove or slot-like Wells 16 on their of the insulation displacement contact 11 remote end face by a molded End wall 27 is closed, as is shown in FIGS. 7, 8 is shown. Such a junction is special for use at the beginning or end of the line suitable. In continuation of this thought the end wall 27 also in the form of a thin spray skin or be designed with predetermined breaking lines or the like, so that when you press the line 20 into the extension 16 can be broken out. You can also use both extensions 16 of junction 2 with correspondingly break-out End walls.

Such an end closure of the slot or groove-like depressions 16 can also be used in other ways will be realized. An example of this is shown in FIG. 9 to 11 illustrates. In this embodiment are on the side walls 9, 10 in the vicinity of the housing end walls molded on the inside elastically pivotable wing 28, the arranged overlapping each other and on the insertion side are each provided with an insertion bevel 29. At the Pushing a line 20 into the respective slot or groove-like extension 16 give way to the wings 26 elastically to the side, with the inside against the side walls 9, 10 put on and in the soft insulation material of the cable press in so that they simultaneously have an additional Form strain relief.

Automatic wiring from the described Connection points 2 trained devices or components is carried out using a cable laying device in the form of a line laying tool, like it is basically shown in Fig. 1. The cable laying means has a housing 30 attached to an industrial robot or attached to a portal handling device is that it allows the line laying means in terms of a standby position, device to be wired to the programmed To move cable laying routes. This is in detail DE 42 18 741 A1 (US Pat. No. 5,515,606). On the In this respect, disclosure of this publication is referred to. At the bottom of the housing 30 is a vertical one Line laying finger 31 arranged, its substantially rectangular cross-sectional shape at 32 for example in Fig. 20 is indicated. The laying finger rounded below 31 contains a cable routing channel 33, which then to a straight piece of canal near the lower end of the laying finger 31 is curved by 90 ° and in a flat side surface 34 of the laying finger 31 with a line outlet opening 35 at a short distance opens from the bottom side 36 of the laying finger 31. The Cable routing channel 33 takes place in the housing 30 Continued in a guide tube one out of two at 34 (Fig. 1) indicated pairs of tape rolls and looped around it endless drive belts 35 existing belt drive is assigned for line 20, which is in the range of Housing 30 only indicated by a dashed line is. The belt drive is a measuring system for that Line 20 upstream of which only one measuring wheel 70 is indicated. The training of this belt drive is known and therefore not explained further. So far also referred to DE 42 18 741 A1 (US Pat. No. 5,515,606). The belt drive allows that from a supply roll endlessly fed line 20 in synchronization with to promote the movement of the laying finger 31 in such a way that the line emerging from the outlet opening 35 voltage-free between the connection points to be contacted is relocated.

An image processing system attached to the housing 30 360 forms 370 with its image recording device Position sensor, which allow the laying finger 31 when Control of a junction 2 exactly in the correct position relative to position this.

On the vertical side surface 34 of the laying finger 31 is designed in the manner of a pressure stamp Pressure member 37 (Fig. 20, 21) vertically displaceably mounted, that with its own actuator 380 in the housing 30 (Fig. 1) is coupled, which allows it Pressure member 37 program-controlled relative to the laying finger 31 to move vertically. On its side surface 34 of the pressure member 3 adjacent side is Pressure member 37 designed to act as a cutting means. To this purpose is in the illustrated embodiment the pressure member of a replaceable as a wear part Knife blade 38 attached, the part-circular designed Cutting edge 390, the movement of the pressure member 37 join in, directly along the side surface 34 slides and with the edge forming the counter knife the line outlet opening 35, the line 20 on the Can cut off line outlet opening 35. The knife blade 38 is narrower than the laying finger 31 and points only a small thickness, as shown, for example, in FIG. 20 can be seen.

The downward face of the pressure member 37 is with a running along its length symmetrical fillet 40 part-circular cross-sectional shape provided, the radius of the outside diameter of the contacting line 20 is adapted. This will achieved that from the outlet opening 345 horizontally exiting line piece taken from the groove 40 and is guided laterally in this. The knife blade 38 is with its cutting edge 390 opposite the fillet 40 light. set back to a possible sharp edge and an undesirable resistance in line promotion to avoid. Possible differences in height of the end face of the pressure member 37 and the upper edge of the line outlet opening 35 can be compensated by that the lower geometry of the pressure member 37 is nearby the side surface 34 of the laying finger 31 at 41 slightly is beveled, which if necessary, a counterpart of the cable end after exiting the laying finger 31 is achieved.

The pressure member 37 has one in its lower part essentially rectangular, laterally delimited Shape up, being its wall thickness or maximum Thickness not much larger than the outside diameter of the Isolation of the line 20 to be contacted. It is on its two opposite broad sides with parallel, profile grooves facing each other in pairs 42, 43 provided that go through to the lower end face and two in a common plane of symmetry 45 (FIG. 25) horizontal web-like, narrow pressure surface sections 46, 47 limit laterally, the width of each width an insulation displacement slot 12 is adapted. she is in in any case smaller than the diameter of the conductor contacting line 20. The two pressure surface sections 46, 47 are of equal length and in a mutual Distance arranged on the grid dimension of the junction is coordinated. As in particular from FIG. 25 can be seen, each of the pressure surface sections 46, 47th in the longitudinal direction by two strip-shaped guide sections 48, 49 larger width or wall thickness limited, whose width with play approximately the width of the insertion slots 15 and the receiving slots 23, if present at the front end of the respective slot or groove-like Extension 16 corresponds. The guide sections 48, 49 can on the side facing the printing surface 46 bevelled or rounded at the edges, like this is indicated at the guide sections 48. In particular Figures 21, 22 and 25 show that the wall thickness 32nd of the pressure member 37 is selected so that it in the slot or groove-like extensions 16 of the junction 2 with side play can immerse.

The width of the grooves 42, 43 is the same size and to that Adjusted grid size of the connection point in such a way that as can be seen in particular from FIGS. 23 to 25, in in the an extension 16 immersing pressure member 37 the two guide sections 48, 49 of the insulation displacement slot 12 inserted pressure surface section 46 in the two insertion slots 15 of this insulation displacement contact 11 are added during the contacting zone 3 delimiting rib-like or strip-like projections 14 between the knife blade 38 and the opposite Side wall of the groove 43 lie with lateral play. In the 20 to 22 by a detent distance displaced position, the pressure member 37 is immersed in both extensions 16 one, the pressure surface section 46 is inserted into the insulation displacement slot 12. The guide sections adjacent to the pressure surface section 46 48, 49 reach into the outside again two guide slots 15 of the contact zone 3, while the knife blade 38 on the outside next to the Housing 4 is located.

The pressure member 37 can therefore when immersed in the slot or groove-like extensions 16 and in the Chamber of contact zone 3 in junction 2 at the same time, an exact correct positioning and positioning of the respective pressure surface section 46 or 47 to the insulation displacement slot 12 on which the contact of the line 20 to be pressed in takes place.

The distance between the two is an indentation zone forming pressure surface sections 46, 47 can thus be found in the junction geometry again. The division edge left - middle of contact edge right of connection point 2 limiting housing parts is thus with the distance and the length of the pressure surface sections 46, 47 formed indentation zones matched so that a collision of the pressure member 37 with housing parts when pressing and Contacting line 20 is excluded.

The automatic wiring of those described at the beginning Junction points 2 by means of the above Line laying means is illustrated in FIGS. 20 to 24:

The pressure member 37 isc by its actuator 380 with respect to the laying finger 31 in three different Positions adjustable:

In a first position, which is used to extend the Pressure member 37 and the laying finger 31 from a connection point serves, is the pressure member 37, after 22 at such a distance above the line outlet opening 35 that it is freely exposed and the laying finger 31, with the simultaneous output of the the junction contacted line 20 without hindrance through housing parts of junction 2 of this can be moved horizontally.

In a second position, the starting position for Contact in particular the beginning of the line and 20, the pressure member 37 is so that its pressure surface 46, 47 at least with that of the laying finger 31 adjacent pressure surface section 47 a smooth transition to the upper edge of the cable duct 33 in the area of the line outlet opening 35 of the laying finger 31 forms. As mentioned earlier, is while the knife blade 38 is set back slightly upwards, so that the knife edge 390 feeds the line 20 is not a hindrance in the way. In this position it is horizontal line piece emerging from the outlet opening 35 on the side facing away from junction 2 supported by the pressure surface 46, 47.

In a third position to cut and contact 24 is the pressure member 35 towards the laying finger 31 down advanced so that when crossing the line outlet opening 37 cut cable ends in the Insulation displacement slot 12 of connection point 2 is pressed in is, while the laying finger 31 at a distance above the Housing parts of junction 2 remains held. The Wiring itself happens in the following way:

At the beginning of the wiring along a given The routing path 31 becomes the one at the beginning of the line brought to the contact point to be contacted. The pressure member 37 is on the laying finger 31 in the second position (Fig. 20) transferred. Line 20 will out of the laying finger until it joins their end under that of the laying finger 31 lying pressure surface section 46, i.e. the grooves 42 lies.

The laying finger 31 is over with the pressure member 37 the junction 2 positioned so that the Pressure surface section 46 formed first indentation zone and the middle of the contact zone 3 are aligned. The Parts now take the position of FIG. 20, in which the horizontal line piece lying in the groove 40 and supported by the pressure surface 46, 47 at a distance stands above the housing 4.

Starting from this position, the laying finger will move 31 and the pressure member 37 down together, i.e. the laying finger 31 retains its fixed spatial assignment to the pressure member 37 during this movement. The Pressure member 37 dips into connection point 2 from above a while the laying finger and the knife blade 38 laterally outside the housing 4 of the connection point 2 remain. The pressure member 37 goes with the laying finger 31 until the line 2 in the Insulation displacement slot 12 is contacted properly (Fig. 21).

Then the pressure member 37 becomes stationary when it remains Laying finger 31, relative to laying finger 31 Move up to the first position in which it is in Distance from the housing 4 and thus the connection point stands. The laying finger 31 is closed with the pressure member 37 brought the next connection point 2, the Laying finger 31 and the pressure member 37 in the starting position 20 are transferred.

For wiring through the line 20 at a connection point go after positioning the laying finger over the junction of the laying finger 31 and that Pressure member 37 from the initial position shown in FIG. 20 in the Position according to FIG. 21, whereupon the pressure member 37 22 and returns to the first position the laying finger to the next connection point 2 moves. The through-wired line is at 20a in Fig. 22 indicated by dashed lines.

When contacting the cable end, the laying finger 31 and the pressure member 37 initially in the starting position 23 above the junction transferred in which the pressure member 37 in its second Position is, so that the 35th emerging pipe section on the connection point 2 opposite side supported by the pressure surface 46, 47 is.

The laying finger 37 is so over the junction positioned that the knife blade 38 adjacent Printing surface section 47 and the one formed by them second indentation zone with the middle of the contact zone 3 align (Fig. 23, 25).

With the laying finger 31 held stationary, 23, the pressure member 37 pushed down into its third position. During this movement, the knife edge first cuts 390 directly at the edge of the outlet opening 35 the line 20, with the opening boundary as a counter knife acts. The cut end of the line is at the very rapid movement of the pressure member 37, also by the Groove 40, on the end face of the pressure member 37 and held in particular the pressure surface 39 and into the insertion slots 15 and pressed into the insulation displacement slot 12, until the position shown in FIG. 24 is reached. How a look at Figs. 24, 25 shows the cutting is done the cable in the immediate vicinity of the insulation displacement contact 11th

The pressure member 37 then returns to the first or second position back, with which the line laying means Drive unhindered to the next junction can.

There, as a look at Fig. 25 shows, the knife blade 38 in the associated slot or groove-like extension 16 immersed, this extension 16 can also be front be closed, as already shown in FIGS. 6 to 11 was explained. The same applies analogously to the Conditions at the beginning of the line. This front closure of the line beginning or end of line slot or groove-like extension 16, allowed the terminal connection points even further shorten without touching the bare Endanger cable ends.

In certain cases it can be useful for Cutting the line at the end of the line, take special precautions to prevent the cut off Line end comes free from the pressure member 37, before it enters the insertion slots 15 and if necessary one of the receiving slots 23 is pressed. To this Purpose may line 20 immediately prior to indentation in the insulation displacement slot 12 in the area of the contact zone 3 pre-centered relative to the insulation displacement contact 11 and be pre-fixed. This is achieved in practice, for example. by the training illustrated in Figs. 15, 16 the junction. The two side walls 9, 10 each Junction 2 are in the area of the insertion slots 15 delimiting rib-like or strip-like Projections 14 over the upper edge of the side walls 9, 10 preferred so that molded protruding tongue-shaped Shaped parts 14a, which with insertion bevels 19th are provided and between them an extension of the protrude the insertion slots 15 to the insertion side to let.

26 to 29 is the control of the line laying means when contacting such a connection point illustrated. When contacting the Line beginning corresponding to FIGS. 26, 27 are initially the laying finger 31 and that in the second position standing pressure member 37 above the junction positioned that the printing surface area 46 is centered the contact zone 3 is aligned. The horizontal Line piece 20 already between the tongue-shaped Moldings 14a are brought, so that a pre-centering and pre-fixation of the line is reached before the actual contact is made.

Basically the same applies to through-wiring and for cutting the line, which is based on the Fig. 28, 29 is easy to understand. You can see the line 20 already in the starting position according to FIG. 28 added between the molded parts 14a so that they at the movement into the contact position according to FIG. 29 is not can get free laterally from the pressure member 37.

The rest of the wiring or contacting process is the same as already with reference to FIGS. 20 to 25 described so that on the corresponding explanations Can be referenced.

The automatic wiring method explained above is together with the new line laying equipment, i.e. the laying finger 31 and the pressure member 37, also for wiring connection points can be used according to DE 42 18 741 A1 (US Pat. 5 515 606) with a thickness corresponding to the laying finger 31 Width of the extension 16 of the insertion slots 15 and thus relatively large distances between adjacent connection points are formed. This is of considerable practical importance because in the Practice, e.g. automatic electrical wiring Shine, cases occur where, for example, due to different electrical conditions, connection points both of the known type and that described here new embodiment in one and the same device be used. The full compatibility ensures that regardless of the type of connection points used no hindrance in the automatic Wiring can occur.

The functional sequence when wiring in known Way designed connection points happens in essentially as described in the mentioned publication. In addition, the following should be noted:

When properly in the second position according to FIG. 20 positioned laying finger 31 and pressure member 37 the line 20 passes through the line outlet opening 35 advanced as far as contacting the beginning of the line, that they are below that adjacent to the knife blade 38 Pressure surface section 47, i.e. in the second indentation zone comes to rest. The pressure member 37 and the laying finger 31 then go simultaneously while maintaining their mutual mutual assignment downwards, whereby the laying finger 31 into the associated extension 16 immersed, the width of the thickness of the laying finger is coordinated.

Both when contacting the beginning of the line as well when through-wiring and when contacting the cable end becomes the pressure member 37 with respect to the connection point 2 positioned so that the knife blade 38 is always adjacent Printing area section 47 (second indentation zone) is used.

At the end of the line, the line is cut off contacted. The line is then cut off by a relative movement between the laying finger 31 and the knife blade 38 such that the pressure member holds contacted line in the insulation displacement slot 12, while the laying finger 31 to the insertion side from the Extension 16 is moved out.
