Description

The invention relates to a cable connection component for electrically connecting a shielded multicore cable, having an internal thread having a union nut, with a multiple incisions splice piece of insulating material for singling the wires of the cable and with a shielding element for contacting the shield of the cable, wherein the core insulation of in the splice part introduced wire ends when screwing the nut on a provided with an internal thread corresponding to the external thread provided electrically conductive connection body arranged in the connection body and plunging into the incisions in the splice cutting terminals and contacts the conductors of the wires.

In addition, the invention also relates to a cable connection device and a cable connection device with a cable connection component according to the invention and a device connection component or a cable connection component and a method for mounting a shielding element in a splice part of a cable connection component according to the invention.

From the DE 199 51 455 C1 and the DE 10 2011 108 123 A1 In each case, a cable connection component is known as part of a cable connection device with which the wires of a multicore cable can be connected in a simple manner to the connection elements of a device connection component or a cable connection component, without first having to remove the core insulation of the individual conductors. For example, in the Fig. 6 of the DE 199 51 455 C1 and Fig.1 of the DE 10 2011 108 123 A1 shown cable connection component, the individual wires of the cable are first introduced into the splice part, which is referred to there as a wire receiving and -führungsteil. Then the wire ends are bent and inserted into recesses in the splice part, which serve as restraint locks for the wires during radial deflection. Subsequently, the protruding through the recesses wire ends are cut off, so that then the union nut can be screwed onto the corresponding external thread of a connector body. When screwing the union nut onto the connection body the splice member is pressed into the connector body, wherein the cutting terminals arranged in the connector body penetrate into the incisions provided in the splice part, thereby penetrating the core insulation of the individual wires crossing the incisions and contacting the individual conductors.

Such constructed cable connection or connection devices, which basically already made DE 198 36 662 C2 are known, have proven in practice for over fifteen years extremely well and in particular by the applicant under the product name QUICKON® in various embodiments extensively distributed (see. Prospectus "PLUSCON 2011" pages 92 and 93, Phoenix Contact GmbH & Co. KG ).

Also from the DE 10 2012 103 708 B3 a similar cable connection component is known as part of a connector. The connection component consists of an inner clamping part, along the lateral surface of which a plurality of recesses for the individual wires are arranged, in which clamping ribs are formed, which clamp the wires in the recesses. In addition, the connection component has a positioning sleeve which can be pushed onto the clamping part. The positioning sleeve has radially inwardly directed, wedge-shaped webs which force the individual conductors into an S-shaped path. When mating the connection component with a contacting part, cutting terminals arranged in the contacting part penetrate the insulation of the individual conductors and contact them electrically.

In industrial process and measurement technology, high immunity to interference is often required. It is a decisive factor in the availability of industrial plants in measurement and control technology. In the construction of low-noise system increasingly shielded cables are used to prevent capacitive and inductive electromagnetic couplings in the cable. In this case, one end of the shielded cable is often connected via a plug connector or a cable connection device to an electrical device, for example a sensor-actuator box, and the other end to the supply connection, for example via a terminal block. The contacting of the shield of the cable is done on the side of the device mostly via the metallic sleeve of the connector or the Connecting body, via which the shield is connected to the metallic housing of the electrical device.

The DE 37 34 667 C1 discloses a cable end plug for mounting on a coaxial cable, which is inserted together with the remote end of the coaxial cable in a plug device of a connection device. The cable end plug has two plug sleeve parts made of plastic, between which an annular contact sleeve is arranged. The contact sleeve has an annular disk as a central portion and on both sides of the central portion angeodnete, individual contact tongues. The outer contact tongues serve for contacting the conductive inner wall of the plug-in device and the inner contact tongues for contacting the outer conductor of the coaxial cable.

From practice, various ways are known as the electrically conductive connection between the shield of the cable and the metallic plug sleeve of a connector, which then acts as Schirmungshülse, can be produced. In this case, the shield can be connected either directly or via an additional shielding element with the metallic plug sleeve. From practice connectors are known in which the shield, which is often designed as a shield braid, is soldered directly to the connector sleeve. However, this type of connection of the shield with the plug sleeve requires a relatively high installation cost, and moreover, the soldering process is relatively difficult due to the relatively high mass of the plug sleeve.

In an alternative embodiment of the direct connection of the shield to the connector sleeve, a portion of the cable jacket is removed at the free end of the cable and the shield is pushed back over the adjacent cable jacket before the cable thus prepared is inserted into the connector sleeve. Subsequently, the plug sleeve in the region in which the shield has been pushed back over the cable sheath, deformed so far that the shield between the cable sheath and the connector sleeve is clamped. Such a direct connection of the shield of the cable with a metallic plug sleeve is not without in the previously described cable connection device or the described cable connection component Further possible, because the cable is surrounded within the cable connection component of the existing of insulating material splice part.

The DE 20 2008 004 892 U1 Therefore proposes the use of a cup-shaped, a bottom and an angled collar having screen transfer element that is plugged onto the cable to be connected facing side of the splice. For electrical connection of the shielding of the cable with the metallic plug sleeve of the device connection part, the exposed shielding of the cable is guided outwardly over the collar of the shielding element such that the shielding contacts the external thread of the plug sleeve when the screwed connection is screwed onto it in an electrically conductive manner. The disadvantage here is that to ensure safe forwarding of the shielding the shielding must be placed before connecting the wires of the cable by hand on the collar of the screen transfer element.

From the DE 10 2010 017 265 B4 a cable connection component described above is known in which a shielding element is arranged inside the splice part, where it is referred to as a guide device. The shielding element is designed as a funnel-shaped catching device, which has an annular base part and four in the direction of the longitudinal axis of the splice part or the cable connection component inwardly bent spring elements. In addition, one of the spring elements is connected to a line element extending in the longitudinal direction of the cable connection component, which, like the wires of the cable to be connected, is inserted into the splicing part. When screwing the union nut on the external thread of the connector body, the line element as the cores of the cable is then contacted by an arranged in the connection body insulation displacement terminal. At the time of the DE 10 2010 017 265 B4 Known cable connection device, the electrically conductive connection of the shielding of the cable via the shielding element and the line element thus takes place only with one of the contacts arranged in the connection body.

The invention is therefore based on the object to provide a cable connection component or a cable connection device and a cable connection direction, which is a simple connection of a shielded multicore Cable allows. On a special preparation of the shielding of the cable should be omitted as possible.

This object is achieved in the cable connection component described above with the features of claim 1, characterized in that the splice part on the wire guide part facing side a plurality of latching arms and the wire guide part on the cable receiving part facing side more to the latching arms Has corresponding, inwardly projecting latching hooks. In addition, the shielding element has an annular central portion, a plurality of extending from the central portion in the direction of the wire guide member side facing inner spring arms and a plurality of the central portion in the direction of the wire guide part remote from the side extending outer spring arms. The inner spring arms are bent inwardly in the direction of the longitudinal axis of the cable connection component in such a way that their ends contact the shielding of a connected cable, while the outer spring arms are bent away from the longitudinal axis of the cable connection component in such a way that the outer spring arms between the cable receiving part and the wire guide member, wherein the ends of the outer spring arms protrude from the splice member.

Like the one from the DE 10 2010 017 265 B4 Known cable connection component also serve in the cable connection component according to the invention, the inner spring arms of the electrical contacting of the shielding of the cable. However, in the case of the cable connection component according to the invention, electrical transmission does not take place via a single line element to a single contact of a device connection component, but via the outer spring arms to the metallic connection body of a device connection component or a cable connection component which functions as the shielding sleeve.

Characterized in that the splice part is formed in two parts, namely consists of a cable receiving part and a wire guide part, the possibility has been created in a simple manner to contact the arranged inside the splice part shielding of the cable via the shielding element on the outer circumference of the splice. Due to the fact that the shielding element has a plurality of outer spring arms, a connection of the shield to the metallic connector body at several distributed over the circumference points, which is desirable for a good shield connection. Due to the resilient property of the inner spring arms, the contacting of the shielding of the cable takes place automatically upon insertion of the cable into the cable connection component or into the cable receiving part of the splice part, so that a special, additional preparation of the shield is not required. The connection of the shielded cable is rather as the installer knows from the connection of an unshielded cable to a known from the prior art cable connection component.

According to a preferred embodiment of the cable connection component, the latching arms of the cable receiving part are arranged concentrically to the longitudinal axis of the cable connection component, wherein in the assembled state of cable receiving part and wire guide part facing the cable connection component sleeve-shaped portion of the wire guide part surrounding the latching arms. The sleeve-shaped region of the wire guide part is thus simply plugged onto the latching arms for connection to the cable receiving part, wherein the latching arms engage with the corresponding latching hooks arranged in the interior of the sleeve-shaped region, so that the cable receiving part and the wire guide part are securely connected to one another. Characterized in that the sleeve-shaped portion of the wire guide part surrounds the latching arms of the cable receiving part in the assembled state, the connection area between the cable receiving part and the wire guide part is mechanically protected and beyond the sealing of extending within the latching arms of the cable receiving part wires of the cable.

As has been stated above, the two-part design of the splice part has made it possible to contact via the shielding element the shielding of the cable to be connected outside the splicing part, namely the metallic connecting body, arranged in the interior of the splicing part. For this purpose, the shielding element between the cable receiving part and the wire guide part is arranged, wherein according to a preferred embodiment of the invention, the annular central portion of the Schirmungselements, which connects the inner spring arms with the outer spring arms, is surrounded by the latching arms of the cable receiving part, ie the annular central portion is disposed within the cable receiving portion. The outer spring arms of the Schirmungselements extend through the individual free spaces between the latching arms of the cable receiving part. The annular central portion and the latching arms of the cable receiving part are thereby protected during the locking of cable receiving part and wire guide part by the locking arms of the cable receiving part from damage. For this purpose, the inner spring arms of the shielding element are preferably arranged corresponding to the latching arms of the cable receiving part, ie the inner spring arms and the latching arms have the same angular position in the mounted state.

According to a further advantageous embodiment of the cable connection component according to the invention also the inner spring arms and the outer spring arms are arranged evenly distributed on the circumference of the central portion. As a result, both a good electrical connection of the shield and a simple production of the shielding element, which is preferably a stamped and bent part, made possible. If, as described above, the inner spring elements are arranged corresponding to the latching arms, the outer spring arms are arranged offset to the inner spring arms, since the outer spring arms extend through the spaces between the latching arms.

In addition to the cable connection component described above, the invention also relates to a cable connection device for the electrically conductive connection of a shielded multicore cable to an electrical device. The electrical device may be, for example, a sensor / actuator box. Regardless of this, however, the term "electrical device" is to be understood here in a general way, that is to say, "electrical device". H. The term "electrical device" is intended to include other electrical components, devices and devices.

Such a cable connection device has, in addition to the previously described cable connection component, a device connection component which has a metallic connection body with an external thread corresponding to the internal thread of the union nut. In addition, a plurality of insulation displacement terminals and connection elements connected to the individual insulation displacement terminals are provided in the connection body, wherein the insulation displacement terminals are arranged on the side facing the cable connection component side and the connection elements on the side facing away from the cable connection component side. Often these are integrally formed metal parts which are formed on one side as insulation displacement terminals and on the other side as connection elements. The connection elements may preferably be designed as pin or socket contacts.

Moreover, the present invention also relates to a cable connection device for the electrically conductive connection of two shielded multicore cables. Such a cable connecting device, which is often referred to as a cable connector, in addition to the cable connection component according to the invention still has a cable connection component. The cable connection component has a connection body with an external thread corresponding to the internal thread of the union nut and a plurality of insulation displacement terminals and connection elements arranged in the connection body. As in the case of the device connection component, the insulation displacement terminals on the side facing the cable connection component and the connection elements on the opposite side are also arranged in the cable connection component, wherein the insulation displacement terminals and the connection elements are in turn electrically conductively connected to one another. For the connection elements of the cable connection component, which serve to connect the wires of the second cable, basically the connection techniques known to the person skilled in the art, for example screw connection or spring terminal connection, can be used. Preferably, however, the connection elements of the cable connection component are formed as insulation displacement terminals, so that in the connection body of the cable connection component a plurality of metal parts are arranged, which are formed on both sides as insulation displacement terminals. The connection body then has a second external thread, onto which the union nut of a second cable connection component can be screwed and thus a splice part can be inserted into the connection body.

• Aufstecken des Adernführungsteils auf das Kabelaufnahmeteil, so dass die Rastarme am Kabelaufnahmeteil mit den Rasthaken am Adernführungsteil verrasten.

According to the invention, the splice part with the shielding element or the shielding element is mounted in the splice part according to the features of claim 9. The method has the following essential steps:

• Widening the latching arms of the cable receiving part and inserting the shielding element between the latching arms of the cable receiving part, wherein the outer spring arms of the Schirmungselements extend through the free spaces between the latching arms;
• Attach the wire guide part on the cable receiving part, so that the latching arms engage the cable receiving part with the latching hooks on the wire guide part.

In the method according to the invention, the expansion of the latching arms of the cable receiving part is preferably carried out by means of a dome, which is inserted from the side facing away from the wire guide part in the cable receiving part. If the shielding element is inserted between the latching arms of the cable receiving part, then the mandrel is pulled out of the cable receiving part, so that the latching arms spring back and thereby radially fix the shielding element in its end position. By attaching the wire guide part on the cable receiving part takes place both the latching connection between the wire guide part and the cable receiving part, as well as the axial fixation of the Schirmungselement, as the free ends of the outer spring arms between the cable receiving part facing end side of the wire guide part and a trained stop collar on Cable receiving part to the outside, d. H. out of the splice part, extend.

The Fig. 1 shows a cable connection component 1 according to the invention for connecting a in the Fig. 2 and 7 The cable 2 has a plurality of wires 21, a shielding 22 surrounding all cores 21 together and a cable jacket 23 surrounding the shielding 22. To the cable connection component 1 in particular include an internal thread 3 having a union nut 4, a plurality of incisions 5 having splice 6 of insulating material and a shielding element 7. If the union nut 4 is screwed with its internal thread 3 on a corresponding external thread 8 having metallic terminal body 9, so the splice member 6 is pressed into the cylindrical connector body 9, wherein the cutting terminals 10 arranged in the connector body 9 dive into the recesses 5 in the splice member 6 and penetrate the wire insulation of the individual wires 21, which intersect the incisions 5, and contact the individual wires 21.

As shown in the exploded view according to Fig. 1 is recognizable, this consists separately in Fig. 3 again splice part 6 shown from a cable receiving part 11 and a latchable with the cable receiving part 11 sleeve-shaped wire guide part 12. In this case, the cable receiving part 11 has a plurality of resilient latching arms 13 and the wire guide part 12 to the latching arms 13, inwardly, ie in the direction of the longitudinal axis of the wire guide part 12 facing latching hooks 14.

This in Fig. 1 and in Fig. 6 again separately shown shielding element 7 consists of an approximately annular central portion 15, a plurality of the central portion 15 in the direction of the wire guide member 12 side facing extending inner spring arms 16 and more from the central portion 15 in the direction of the wire guide member 12 side facing outer spring arms 17. In particular out Fig. 2 It can be seen that the inner spring arms 16 are bent inwardly in the direction of the longitudinal axis of the cable connection component 1 in such a way that the ends of the inner spring arms contact the shield 22 of a connected cable 2. In contrast, the outer spring arms 17 are bent from the annular central portion 15 to the outside, ie bent away from the longitudinal axis of the cable connection component 1. In the assembled state of the splice part 6, the outer spring arms 17 extend between the cable receiving part 11 and the wire guide part 12, so that the ends 18 of the outer spring arms 17 protrude outwardly from the splice part 6.

How out Fig. 2 and 3 it can be seen, the latching arms 13 are arranged concentrically to the longitudinal axis of the cable connection component 1 in the assembled state of the cable receiving part 11 and wire guide part 12 of a sleeve-shaped portion 19 of the wire guide part 12 facing the cable receiving part 11. Characterized in that the sleeve-shaped portion 19 of the wire guide part 12 encloses the latching arms 13 of the cable receiving part 11, an unintentional release of the latching connection between the cable receiving part 11 and the wire guide part 12 during insertion of the splice member 6 is prevented in the connector body 9. In addition, there is also a secure seal of the running within the locking arms 13 of the cable receiving part 11 wires 21 of the cable. 2

Fig. 3 shows the splice member 6 in the assembled state, wherein the annular central portion 15 of the Schirmungselements 7 disposed within the cable receiving part 11, namely surrounded by the latching arms 13. The outer spring arms 17 of the Schirmungselements 7 extend through the spaces 20 between the individual locking arms 13. It can be seen that both the inner spring arms 16 and the outer spring arms 17 are arranged evenly distributed on the circumference of the central portion 15, wherein the inner spring arms 16 are arranged offset to the outer spring arms 17 so that the inner spring arms 16 have the same angular position as the latching arms 13, so that in each case an inner spring arm 16 is covered by a corresponding latching arm 13.

From the enlarged view of the Schirmungselements 7 according to Fig. 6 In addition, it can be seen that the width of the inner spring arms 16 is reduced from the central portion 15 towards its end, the ends being bent outwardly to facilitate the contacting of the shield 22 of the cable 2. The opening formed by the free ends of the inner spring arms 16 has a diameter which is slightly smaller than the outer diameter of the shield 22, so that upon insertion of a cable 2 through the Schirmungselement 7, the inner spring arms 16 are slightly deflected. As a result, a secure and good electrical contacting of the shield 22 is ensured by the ends of the inner spring arms 16.

As the width of the inner spring arms 16 decreases toward its end, the width of the outer spring arms 17 increases from the central portion 15 to their ends 18, the ends 18 being approximately V-shaped in the illustrated embodiment. In this way, it is achieved that the ends 18 of the outer spring arms 17 projecting outward from the splicing part 6 make contact with the inner circumference of the metallic connecting body 9 at a plurality of points distributed over the circumference of the connecting body 9. At the same time, the splitting of the ends 18 of the outer spring arms 17 increases their elasticity, which likewise has a positive effect on the electrical connection between the ends 18 of the outer spring arms 17 and the inner surface of the metallic connection body 9.

How out Fig. 1 it can be seen, the cable connection component 1 still has an annular seal 24, which forms a Zugentlastungs- and sealing area together with a plurality of annularly formed on the cable receiving part 11 fins 25. The slats 25 cooperate when screwing the union nut 4 with a provided on the inside of the union nut 4 bevel in the manner of a PG gland, so that when screwing the nut 4 on the connector body 9, the fins 25 are pressed against the seal 24, resulting in a seal and at the same time a strain relief of an inserted cable 2.

In the Fig. 7 The cable connection device 26 comprises a cable connection component 1 and a device connection component 27. The device connection component 27 has a metallic connection body 9 with an external thread 8 and a number of insulation displacement terminals 10 corresponding to the number of leads 21 to be connected and connection elements 28 connected in an electrically conductive manner to the insulation displacement terminals 10. In the present case, the connection elements 28 are designed as pin contacts, which are each soldered or welded to the insulation displacement terminals 10. At the in Fig. 7 illustrated embodiment of the cable connection device 26, the device connection component 27 is formed as a connector. The connection body 9 has on the side facing away from the cable connection component 1 a second external thread 29, which is rotatable and thus can be screwed into a corresponding junction box.

For mounting the splice part 6 with the shielding element 7, the latching arms 13 of the cable receiving part 11 are first widened, so that the shielding element 7 can be inserted with its middle section 15 between the latching arms 13. The outer spring arms 17 extend through the free spaces 20 between the latching arms 13, so that the ends 18 of the outer spring arms 17 protrude laterally from the cable receiving part 11. If the shielding element 7 is completely inserted between the latching arms 13 of the cable receiving part 11 and the expansion of the latching arms 13 is canceled, then the middle section 15 is clamped between the latching arms 13, so that the shielding element 7 is fixed radially in its position. Now the wire guide member 12 is fitted with its sleeve-shaped portion 19 on the cable receiving part 11, wherein the latching hooks 14 engage with the latching arms 13. At the same time, the portions of the outer spring arms 17 projecting laterally from the cable receiving part 11 are pressed by the end face of the wire guide part 12 facing the cable receiving part 11 against a stop collar 30 formed on the cable receiving part 11, so that the shielding element 7 is also fixed axially in its position.

For electrically conductive connection of a shielded multi-core cable 2, the cable 2 is first introduced into the cable connection component 1 by the end of the cable 2 is pushed through the rear opening in the union nut 4 as far into the splice member 6, that the individual wire ends on the union nut 4 facing away from the splice 6 and the wire guide part 12 protrude. Subsequently, the individual wire ends are folded by about 90 ° to the outside and pressed into the formed in the wire guide part 12 recesses 31, which serve as restraint locks for the wire ends (see. Fig. 2 ). In this case, when the cable 2 is inserted into the splicing part 6 or the cable receiving part 11, the shielding 22 of the cable 2 is automatically contacted by the ends of the inner spring arms 16, so that no additional steps are required for contacting the shielding 22 of the cable 2.

When screwing the union nut 4 on the external thread 8 of the metallic terminal body 9, the splice member 6 is inserted into the connector body 9, wherein the arranged in the connector body 9 insulation displacement plugs 10 in the core guide member 12 formed, dive open at the front incisions 5, whereby a reliable contact of the Incisions 5 crossing, outwardly folded wire ends is ensured by the insulation displacement terminals 10. At the same time there is a resilient abutment of the ends 18 of the outer spring arms 17 on the inner circumference of the metallic connection body 9, whereby a secure electrical connection of the shield 22 is given via the shielding element 7 to the metallic connection body 9.
