First of all, it will be explained in the following which of the terms used in the following description, first of all of the prior art, then of the invention, which meaning should or should have:

a) The term cable stands for an electrical line that has at least one wire, but usually has multiple wires; if there are several wires, it is called a multi-core cable.

b) The wires of a cable consist of a conductor and a wire insulation.

c) In a cable, the conductors which are insulated per se, that is to say the conductors each provided with a core insulation, are surrounded in their entirety by further insulation, the cable insulation.

In the introduction it is said that the invention is a cable connection or connection device For the electrically conductive connection of a cable to an electrical device or relates to the electrically conductive connection of two cables. Is it about that Connecting a cable to an electrical device, there is a cable connection device in front; if two cables are to be connected to one another, it is a question of a cable connection device. In the following, we will always focus on one Cable connection device turned off. Nevertheless, there is always a cable connection device in the sense explained above.

In the introduction it is also said that the cable connection device for the electrically conductive Connecting a cable to an electrical device is intended. Here is electrical To understand the device in general; in particular, the term electrical Device also includes electrical components, devices and devices.

The cable connection in question exists from its basic structure Connection device from a cable connection component and a device connection component or from a first cable connection component and a second cable connection component. If it is a cable connection device, then belong for this purpose a cable connection component and a device connection component. There is a cable connector before, this includes a first cable connection component and a second cable connection component.

It is initially deliberately left open which of the individual parts of the union nut, wire receiving and guiding part, clamping and connection unit and connection or connection body belong to the cable connection component or the first cable connection component or to the device connection component or the second cable connection component. In this respect, it should be added

that the union nut generally belongs to the cable connection component or the first cable connection component, but an embodiment is also conceivable in which the union nut belongs to the device connection component or the second cable connection component,

that the wire receiving and guiding part belongs to the cable connection component or the first cable connection component,

that the clamping and connection unit belongs to the device connection component or the second cable connection component and

that the connection or connection body usually belongs to the device connection component or the second cable connection component, but an embodiment is also conceivable in which the connection or connection body belongs to the cable connection component or the first cable connection component, namely when the union nut is closed belongs to the device connection component or the second cable connection component, as is shown as a possible embodiment further above.

In the introduction it is further stated that those contacting the insulation displacement terminals or the wire ends to be clamped in by the insulation displacement terminals and the associated Insulation clamps run at an angle of less than 180 °. At first that only says that the wire ends and the assigned insulation displacement terminals are not parallel to each other run because then a functional function of the insulation displacement clamps on the Wire ends is not possible. The angle between those with the insulation displacement clamps contacting or to be clamped by the insulation displacement wire ends and Both the pointed and the right one can be assigned to the assigned insulation displacement clamps Be angle; an obtuse angle is also not excluded.

Finally, it is said in the introduction that when screwing the union nut on Connection or connection body or when screwing in the connection or Connecting body in the union nut the insulation displacement connectors the wire insulation cut the wire ends and contact with the conductors. The screwing on the union nut on the connecting or connecting body or screwing in of the connector body in the union nut leads to one Relative movement between the wire receiving and guiding part and the clamping and Connection unit and thus to a relative movement between the wire ends and the insulation displacement clamps. This relative movement leads to the insulation displacement terminals Cut the wire insulation of the wire ends and then contact the conductors.

One reduces, only for better understanding, in no way restrictive, the speech in question standing cable connection or connection device to a cable connection device with preferred assignment of the individual components to the cable connection component on the one hand and on the device connection component on the other hand, so it is about a Cable connection device for electrically conductive connection of a preferably Multi-core cable to an electrical device, with a cable connection component and with a device connector, with a cable nut to the cable connector and a wire receiving and guiding part and to the device connection component a clamping and connection unit provided with insulation displacement terminals and with connection elements and a sleeve-shaped one with an internal thread of the union nut corresponding external thread provided connector body, where those to be contacted with the insulation displacement terminals or to be clamped in by the insulation displacement terminals Wire ends and the assigned insulation displacement clamps at an angle run less than 180 ° and when screwing on the union nut cut the connector body the insulation piercing the wire insulation of the wire ends and contact with the leaders.

The individual parts mentioned above are now in need of explanation Wire receiving and guiding part, clamping and connection unit and connection or Connecting body. The following explanation of these items refers to the previously mentioned cable connection device, in which case the connection or Connection body is only referred to as a connector body.

The wire receiving and guiding part belonging to the cable connection component is Usually on the cable side with a receiving or insertion opening for the whole all wires or with a number corresponding to the number of wires Provide receiving or insertion openings for the individual wires. Moreover the wire receiving and guiding part is provided with wire guiding channels. Know the wire receiving and guiding part on the cable side only one receiving or insertion opening on, this receiving or insertion opening branches out then into the individual wire guide channels. However, the cable side is one of the number of cores to be inserted corresponding number of receiving or insertion openings realized, then go to the individual intake or insertion openings into the wire guide channels.

The wire guide channels implemented in the wire receiving and guiding part are taking into account the geometry and the arrangement of the insulation displacement terminals the clamping and connection unit designed and guided so that the with the insulation displacement terminals wire ends making contact or to be clamped in by the insulation displacement terminals and the assigned insulation displacement clamps run at the desired angle, for example at an acute angle or at a right angle.

The clamping and connection unit belonging to the device connection component is on the the side facing the wire receiving and guiding part with insulation displacement clamps the other side with connection elements. It is in the Usually one-piece metal parts, on one side as insulation displacement clamps and are designed on the other side as connection elements. In addition, like insulation displacement clamps function and can be carried out in detail, reference is made to German Offenlegungsschriften 24 59 069, 26 21 507, 27 25 551, 28 56 549, 197 49 622, the German interpretations 19 13 992, 2 010 436, 2 339 800, the German patents 29 02 536, 32 39 708 and the German utility model 298 02 412. The design and configuration of the connection elements depends on the type of connection for the internal wiring of the corresponding electrical device is desired or available. In particular can the connection elements as flat plug, wire wrap or as solder connection elements be executed.

As with the cable connection device in question, the union nut and the core receiving and guiding part the two essential functional elements represent the cable connection component, form the sleeve-shaped, with an internal thread connecting body corresponding to the union nut and the clamping and provided with insulation piercing and connection elements Connection unit, the two essential functional elements of the device connection component. In the screwed state, d. H. then when the cap nut is on the connection body is screwed on, form the union nut and the connection body a closed housing that the inner functional elements, namely the Wire receiving and guiding part and the clamping and connection unit and encloses.

The state of the art initially includes insulation displacement clamps, which includes the publications may be referenced, which have already been mentioned above.

The prior art also includes cable connection devices as described above Type in which, however, the wire ends are radial or essentially radial are inserted into appropriately designed and arranged insulation displacement terminals, the radial movement of the wire ends is derived from an axial movement, namely the screwing of a union nut onto a connector body, the one has the external thread corresponding to the internal thread of the union nut (see German patents 31 50 568 and 32 20 006).

The cable connection or connection device, of which the invention concretely is known from German utility model 295 12 585, which in essential content-equivalent PCT-Offenlegungsschrift WO 97 / 06.580 and from Company brochure of the company Phoenix Contact GmbH & Co. "QUICKON Q 1.5 ...", "Schnellanschlußtechnik" part catalog 2 (March 1997). There are still several further individual parts are provided and details realized which have not been described previously have been.

First of all there are at least one sealing element for axial and radial sealing and a strain relief available when screwing on the union nut the connecting or connecting body as the corresponding items of a so-called Pg screwing act, whereby the strain relief affects the cable Strain relief is. Where electrical conductors contact with insulation displacement terminals, it is of particular importance that the contact points between the conductor and the insulation displacement "are immobilized" so that the contact points largely are sealed gastight and remain locked. Therefore at the Cable connection or connection device from which the invention is based, in addition to the previously described strain relief for the cable implemented a strain relief for the individual conductors. Are specific the wire guide channels provided in the wire receiving and guiding part circumferential ribs.

Incidentally, in the known cable connection or connection device Provide the core receiving and guiding part with incisions that differ from that of the clamping and Project connection side facing inwards. When assembling of cable connection component and device connection component or of the first cable connection component and second cable connection component, specifically when screwing on the union nut on the connecting or connecting body, penetrate the Insulation displacement of the clamping and connection unit successively into that in the Incisions and guide part provided incisions, penetrate the Wire insulation of the individual wires and then contact the individual conductors.

Is the known cable connection or connection device as a cable connection device executed, the connector body is preferably on its the cable connection component specially designed opposite side, namely with a hexagon and a screw-in or plug-in part extending away therefrom. Relevant details result in particular from the company brochure of the Phoenix Contact GmbH & Co. "QUICKON Q 1.5 ...", "Quick connection technology", Partial catalog 2 (March 1997).

Finally, in the known cable connection or connecting device between the wire receiving and guiding part and the device connection component or effective coding elements are provided for the second cable connection component, for example a groove or grooves on the wire receiving and guiding part and an associated one Spring or associated springs on the device connection component or on the second Cable connection component (or vice versa). The part of the coding elements that on Device connection component or on the second cable connection component is realized, can on the connecting or connecting body, on the clamping and connection unit or both on the connection or connection body as well as on the clamping and connection unit be realized. The coding elements can only do one task, however also have two tasks. If the coding elements have only one task, there is these in the correct assignment between the wire receiving and guiding part on the one hand and the clamping and connection unit on the other hand, to the extent that to ensure that the insulation displacement clamps are inserted into the incisions with which the wire receiving and guiding part is provided. To solve The coding elements also have a second task, so this is the correct assignment a specific wire of the cable to a specific insulation displacement terminal Ensure the clamping and connection unit.

The known cable connection or connection device described in detail above, which is a fundamentally new quick connection or quick connection technology has already proven itself extremely well in practice. Nevertheless are improvements, refinements and Further developments displayed, which is to teach the object of the invention.

In the known cable connection or connection device are the union nut and the wire take-up and guide part two individual parts that go together are not fixed. A radial fixation is also not permitted, because yes when screwing on the union nut on the connecting or connecting body itself The wire receiving and guiding part must not turn or cannot turn. The Axial fixation which has not been achieved has the consequence that when the Connection or connection after unscrewing the union nut from the connecting or connecting body, the cable is initially connected or remains connected because the insulation displacement terminals of the clamping and connection unit "hold" the clamped ladders. It is therefore necessary to disconnect the connection or the connection after unscrewing the union nut from the Connection or connecting body still an additional loosening of the Insulation-locked conductor.

A first embodiment according to the invention of the cable connection or connection device described in the introduction, in which the problem shown above has been solved is, is initially and essentially characterized in that the wire receiving and guiding part is axially fixed in the union nut. That has the most significant Advantage that the axial relative movement between unscrewing the union nut from the connecting or connecting body the union nut and the connecting or connecting body also an axial Relative movement between the wire receiving and guiding part and the connecting or connecting body, which inevitably leads to the fact that the previously in the Insulation displacement clamps free the clamped conductor. Is realized in the cable connection or connection device according to the invention, as also in the prior art, the clamping and connection unit fixed in the connection or connecting body, so then according to the invention there is a cable connection or connection device, which - functionally - consists of only two components, namely the cable connection component or the first cable connection component on the one hand and the device connection component or the second cable connection component on the other.

In the known cable connection or connection device, of which the invention goes out for the wire receiving and guiding part that it with the cable side a receiving or insertion opening for all the wires is that this receiving or insertion opening then into individual wire guide channels branches and that the wire guide channels at an acute angle to the longitudinal axis of the wire receiving and guiding part and thus to the longitudinal axis the cable connection or connection device. As in the prior art already realized, is achieved in that the axial insertion of the cable into the Cable connection or connection device or the axial insertion of the wires into the receiving or insertion opening of the wire receiving and guiding part causes the individual wires to the levels of the corresponding insulation displacement terminals cross, - so that when the cable connection component or the first cable connection component relative to the device connection component or to the second cable connection component is moved (or vice versa), in the areas of the introduced Wires that cross the levels of the corresponding insulation displacement connectors make contact between the insulation displacement terminals and the conductors of the individual wires. The previously described in detail the routing of the individual wires of a to be connected or to be connected cable has the advantage that the axial insertion of a cable or the individual wires of a cable "automatically" leads to that the wires cross the levels of the assigned insulation displacement terminals. In certain circumstances However, it can be disadvantageous that the insertion of the cable or the individual Cores "stiff" is because when inserting the cable or the individual Veins are the wires routed to the wire routing channels.

A second embodiment of the cable connection or connection device described at the outset, in which the problem outlined above is solved is, is initially and essentially characterized in that the in the Wire receiving and guiding part provided wire guide channels at least in run essentially coaxially to one another and are open on the one hand and on the other hand, open into contact pockets that are open radially outwards. While thus in the known cable connection or connection device, of which the invention goes out when inserting the cable or the individual wires of the cable in the wire receiving and guiding part the individual wires in the wire guide channels are deflected, such a deflection takes place in the previously described embodiment according to the invention does not take place. Rather, the individual Lead wires through the wire guide channels until they emerge from the front. Then the individual wires are made by hand - or by using one prepared tool - turned to the outside, namely in the contact pocket brought; then protruding from the contact pockets Wire ends are cut off. By moving the face out first in the contact pockets then what takes place in the prior art from which the invention is based already by inserting the veins or by passing the Cores are made through the core guide channels; which is initially on one side of the plane of the assigned insulation displacement leads come with the wire ends to the other side of the levels of the insulation displacement clamps, so cross these levels. As in the prior art, the relative axial movement of the cable connection component then leads or first cable connection component and device connection part or second cable connecting part to each other so that the insulation displacement connectors first Cut the wire insulation of the individual wires and then contact the individual conductors.

The invention relates to a cable connection or connection device for the electrically conductive connection of a cable 1 to an electrical, not shown Device or, which is not shown, for the electrically conductive connection of two cables. As shown, it is about connecting a cable 1 to an electrical one Device, there is a cable connection device; are supposed to be two cables together are connected, it is a cable connection device. In the following, for the sake of simplicity, only one cable connection device is used switched off. As from the cable connection device shown, a cable connection device arises, the person skilled in particular takes from the PCT-Offenlegungsschrift WO 97 / 06.580, cf. the cable connection device shown in Figs. 1 to 4 with the cable connection device shown in FIG. 5.

In terms of its basic structure, there is the one shown overall in FIG. 4 only Cable connection device from a - shown in all figures - cable connection component 2 and a - only shown in Fig. 4 - device connection component 3. In individual belong to the cable connection device shown a union nut 4, a wire receiving and guiding part 5, one with insulation displacement terminals 6 and with Connection elements 7 provided clamping and connection unit 8 and a sleeve-shaped, with an external thread corresponding to the internal thread 9 of the union nut 4 10 provided connector body 11.

It can be seen from all the figures, in particular FIG. 1, that the cable 1 is multi-core, namely has three cores 12. The individual wires 12 of the cable 1 each consist of a conductor 13 and a core insulation 14. In their entirety the wires 12 are surrounded by a cable insulation 15.

As in the prior art, those to be contacted with the insulation displacement terminals 6 or the wire ends 16 of the wires 12 to be clamped in by the insulation displacement terminals 6 and the associated insulation displacement terminals 6 at an angle of less than 180 °, specifically at an acute angle or at a right angle. When screwing on the Union nut 4 on the connector body 11 is the core insulation 14 of the Wire ends 16 severed; then the insulation displacement contacts 6 contact the conductors 13 of the individual wires 12.

As can be seen in all the figures, the union nut 4 and that belong Wire receiving and guiding part 5 to the cable connection component 2, while how 4 shows the clamping and connecting unit 8 and the connecting body 11 the device connection component 3 belong.

The wire receiving and guiding part 5 belonging to the cable connection component 2 is provided on the cable side with a receiving or insertion opening 17. Moreover the wire receiving and guiding part 5 has wire guiding channels 18. The receiving or insertion opening 17 merges into the wire guide channels 18.

The clamping and connection unit 8 belonging to the device connection component 3 is open the side facing the wire receiving and guiding part 5 with the insulation displacement terminals 6, provided on the other side with the connection elements 7. It deals are one-piece metal parts with the insulation displacement clamps on one side 6 and on the other side have the connection elements 7. About how the insulation displacement terminals 6 function and can be carried out in detail referred to the previously published pre-published publications; in particular 1 to 4 of the German utility model 295 12 585th and to FIGS. 1 to 5 of the substantially identical PCT laid-open specification WO 97 / 06.580 and further on page 2, right picture, of the company's prospectus Phoenix Contact GmbH & Co. "QUICKON Q 1.5 ...", "Quick connection technology", partial catalog 2 (March 1997). As shown in FIGS. 1 and 2 of the German utility model 295 12 585 and PCT publication WO 97 / 06.580 show, in the present case is only hinted at in the figures, is the wire receiving and -guide part 5 provided with incisions 19 by the of the clamping and connection unit 8 facing side inwards, ie into the inside of the wire receptacle and - Guide part 5 protrude. When joining cable connection component 2 and device connection component 3, specifically when screwing the union nut 4 onto the Connection body 11, penetrate the insulation displacement terminals 6 of the clamping and connection unit 8 successively into the incisions provided in the wire receiving and guiding part 5 19, penetrate the wire insulation 14 of the individual wires 12 and contact then the individual conductors 13.

According to the first teaching of the invention, the wire receiving and guiding part is 5 in the union nut 4 axially fixed. This has the very significant advantage that with unscrewing the union nut 4 from the connector body 11 axial relative movement between the union nut 4 and the connecting body 11 then an axial relative movement between the wire receiving and guiding part 5 and the connector body 11, which inevitably leads to the previously now free conductor 13 clamped in the insulation displacement terminals 6. Since in the invention Cable connection device, the clamping and connection unit 8 in the connector body 11 is fixed, namely an integral part of the connector body 11, there is a cable connection device according to the invention which is functional - Consists of only two components, namely the cable connection component 2 and the Device connection component 3.

In the illustrated and previously described special embodiment of a cable connection device according to the invention is the previously in its essential Structure of the first teaching of the invention explained and developed what in following will be explained.

First, in the illustrated embodiment, between the cable end of the wire receiving and guiding part 5 and the cable-side end of the union nut 4 a cable receptacle 20 is provided. This cable holder 20 could be made in one piece with the wire receiving and guiding part 5. In the illustrated In the exemplary embodiment, the cable receptacle 20 is, however, designed as a separate component from the wire receptacle and guide part 5 and is axially fixed to the wire receptacle and guide part 5 by a non-positive or positive connection; axial fixation is sufficient, radial fixation can be achieved be, but need not be realized.

The first measure according to the invention - axial fixation of the wire receptacle and guide part 5 in the union nut 4 - is in the illustrated embodiment concretely realized in that the union nut 4 at its cable end a circumferential fixing flange 21 is provided and the cable receptacle 20 a Fixing flange 21 of the union nut 4 assigned circumferential fixing groove 22.

As again shown in the figures, one applies to the illustrated embodiment Cable connection device according to the invention that the cable receptacle 20 a - preferably made of a soft elastic material - sleeve-shaped strain relief 23 has. The strain relief 23 can and is tensioned in the axial direction effective by axial clamping as strain relief, namely that the axial Clamping leads to a reduction in the inner diameter.

Otherwise, the figures, in particular Fig. 4, show that in the illustrated embodiment the cable receptacle 20 is provided with a sealing ring 24 and the Sealing ring 24 with the union nut 4 screwed onto the connector body 11 the end of the connecting body 11 facing the union nut 4 lies sealingly. It is easy to understand that screwing on the union nut 4 on the connector body 11 for an axial tensioning of the sealing ring 24 and - accompanying this - leads to a radial expansion.

According to the second teaching of the invention is that shown and described so far Cable connection device further characterized in that the wire guide channels 18 provided in the wire receiving and guiding part 5 are coaxial with one another run and on the one hand are open at the end and on the other hand in radially contact pockets 25 open on the outside. So while with the known Cable connection device, from which the invention is based, when inserting the cable or the individual wires of the cable in the wire receiving and guiding part individual wires in the wire guide channels will be redirected Not deflection in the embodiment of the invention described above instead of. Rather, in the embodiment according to the invention, the individual Cores 12 of the cable 1 passed through the wire guide channels 18 until they emerge at the end, as shown in Fig. 2. Then the individual Cores 12 by hand - if necessary also using a tool provided for this - turned outwards, namely brought into the contacting pockets 25, as in 3 and 4 is shown. By moving the front end of the Wire receiving and guiding part 5 leaked wires 12 into the contacting pockets 25 then takes place what is in the prior art of which the invention starts, already by inserting the veins or by passing the Cores are made through the core guide channels; which is initially on one side of the plane the associated insulation displacement terminals 6 wires 12 arrive with the wire ends 16 to the other side of the levels of the insulation displacement terminals 6, that is to say cross them Levels. As in the prior art, the relative axial movement of Cable connection component 2 and device connection part 3 to each other, that is, the screwing the union nut 4 on the connector body 11, so that the insulation displacement contacts 6th first cut the wire insulation 14 of the individual wires 12 and then the individual Contact conductor 13.

In the illustrated and previously described special embodiment of a cable connection device according to the invention is the previously in its essential Structure explained second teaching of the invention designed and further developed what will be explained below.

In the cable connection device from which the invention is based, it is necessary for the function to that the wire receiving and guiding part separate wire guide channels has, because these wire guide channels have the task of the introduced To redirect the wires so that the wire ends cross the levels of the insulation displacement terminals. Since in the cable connection device according to the invention the previously explained necessity is not given, it is also not necessary that the wire intake and guide part 5 has separate wire guide channels 18. Rather, they can Wire guide channels 18, which are functionally required for each wire 12 of the cable 1, in the present case, three wire guide channels 18 are combined spatially and structurally be, i.e. merge into one another without material separation.

In the embodiment of a cable connection device according to the second teaching the invention, which has been explained above, it is also possible that the recording or. Insertion opening 17 into the entirety of the wire guide channels 18 without further ado transforms. But it can also offer itself between the receiving or insertion opening 17 and the entirety of the wire guide channels 19, for example to realize step-by-step transition. The stage can then Transition between the receiving or insertion opening 17 and the whole the wire guide channels 18 as it were a stop for the inserted cable 1, represent more precisely for its cable insulation 15.

In connection with the explanation of the second teaching of the invention has so far been shown that the provided in the wire receiving and guiding part 5 wire guide channels 18 are open at the end, - so that the individual wires 12 of the cable 1, as shown in Fig. 2, the end face of the wire receiving and guiding part 5 can exit. This is not absolutely necessary. Rather, it is also conceivable an embodiment in which the provided in the wire receiving and guiding part Wire guide channels are closed at the end, a variant, however is not preferable.

For the embodiment of an inventive embodiment shown in the figures Cable connection device now applies that that in the wire receiving and guide part 5 realized contact pockets 25 on the front side "check valve type" are trained. "Check valve type" means that the end-face training of the contacting pockets 25 is such that the wire ends which initially emerge on the end face 16 of the individual wires 12 in the contacting pockets without further ado 25 can be spent, but then "caught" in it, so not without further, also not by the restoring force of the individual wires 12, emerge again can. This "check valve-like" design is in the illustrated embodiment realized in that the contact pockets 25 each end have two passage and closing elements 26, which are designed as elastic tongues are in such a way that they are in the direction of passage, that is to insert the wire ends 16 of the individual wires 12 in the contact pockets 25, "relatively compliant", however are executed "little compliant" against the direction of passage.

Details are not described in connection with the illustrated embodiment, which are realized in the cable connection device, of which the invention goes out, but also realized in the cable connection device according to the invention can be. This applies, for example, to the one explained above individual strain relief, but also for those also above explained coding elements.
