Abstract
Description
TECHNICAL FIELD
[0001] The present invention relates to an insulation connector having a ceramic base body for accommodating at least two electrical conductors and a ceramic sleeve for fixing the electrical conductors to the base body. The present invention also relates to an assembly formed by assembling at least two electrical conductors in the insulation connector. BACKGROUND
[0002] Plug-in connectors for connecting electrical conductors are known in the prior art. For example, in document DE 197 11 376, electrical conductors are brought into electrical contact with each other by means of a plug and a coupling. To this end, the electrical conductors are connected in the plug or coupling with coupling contacts which are mounted in an insulating part of the plug or coupling. In order to bring the coupling parts into reliable contact with each other, the coupling contacts are mounted movably and, in the contact state, are biased towards each other by means of compression springs.
[0003] However, such plug-in connections consist of a number of individual parts, some of which have a complex geometry. The parts of such plug-in connections are therefore most commonly made of plastic by means of injection molding. Parts having a complex geometry can be easily manufactured by means of injection molding. However, the processable materials in such manufacturing processes are generally not suitable for use at high temperatures. SUMMARY
[0004] It is therefore a fundamental object of the present invention to provide an insulation connector and an assembly formed by assembling at least two electrical conductors in the insulation connector, which are capable of reliably connecting electrical conductors even in high-temperature applications.
[0005] A high-temperature application in the sense of the present application is an application in which temperatures of more than 200°C, in particular temperatures of more than 250°C, act on the insulation connector. In the short term, even higher temperatures, for example temperatures of more than 300°C, in particular temperatures of up to 450°C, can act on the insulation connector.
[0006] It must be noted that features which are recited individually in the claims can be combined in any technically meaningful manner with each other (also across the boundaries of the type, for example method and device) and represent other embodiments of the present invention. The description, in particular the description in connection with the figures, characterizes and details the invention additionally.
[0007] It can also be noted that the conjunction "and / or" used hereinafter between two features and linking them to each other is to be interpreted at all times in the following manner: In a first embodiment of the subject matter according to the invention, only the first feature can be provided, in a second embodiment only the second feature can be provided, and in a third embodiment both the first feature and the second feature can be provided at the same time.
[0008] According to the invention, an insulation connector comprising a ceramic base body for accommodating at least two electrical conductors, wherein each electrical conductor is in contact with another electrical conductor, is characterized in that the insulation connector comprises a ceramic sleeve, which can be in a release position and in a fixing position, wherein in the fixing position the electrical conductors are fixed to the ceramic base body by means of the sleeve. In particular, fixed to the base body means that the electrical conductors are forcedly, i.e. form-fittingly, fixed to prevent an undesired removal from the insulation connector in the longitudinal direction and / or in the radial direction of the electrical conductors.
[0009] The base body accommodates a plurality of electrical conductors for contact, i.e. the electrical conductors are connected such that electrical energy can be conducted from one conductor to another conductor. For this purpose, as a rule one individual electrical conductor is brought into contact, i.e. into an electrically conductive connection, with another individual electrical conductor. However, it is also possible to connect more than two electrical conductors with one another.
[0010] It is also conceivable to bring pairs of electrical conductors into contact, wherein the pairs of electrical conductors are not in electrical contact with one another. In this way, electrical cables having a plurality of conductors can be connected with one another by means of the insulation connector.
[0011] If a part of the electrical conductors should not be in contact with one another, for example in the case of an electrical cable having a plurality of parallel electrical conductors, these electrical conductors are spatially separated from one another in the base body. This can be achieved, for example, by means of structures which are separated from one another by webs in the base body. The webs spatially separate the electrical conductors from one another and thus insulate the electrical conductors. At the same time, the webs hinder or prevent electrical flashovers and reduce the leakage current between the electrical conductors.
[0012] The electrical conductors are held by the base body and are fixed in this position by means of the ceramic sleeve. For this purpose, the sleeve can be brought from a release position, in which the electrical conductors can be inserted or plugged into the base body, into a fixing position, in which the conductors are fixed on the base body. By means of the fixing, it is ensured that the electrical conductors remain in contact and cannot slip out of the insulation connector.
[0013] The fixing of the electrical conductors can be achieved, for example, by means of a clamping device within the base body, which has a conical receptacle for the electrical conductors.
[0014] A typical electrical conductor can be an electrical cable having an insulating sheath around an electrically conductive metal core. In this case, the electrically conductive core can consist of a single metal wire or of a plurality of metal wires. An electrical conductor consisting of a plurality of metal wires is also referred to as a strand.
[0015] The electrical contact of the electrical conductors can be achieved by placing the sleeve in a fixed position. Thus, when the sleeve is in the release position, for example when the electrical conductors are loosely inserted into the base body, the electrical conductors can not or not sufficiently be in contact. When the sleeve is then brought into the fixed position, the electrical conductors can be biased towards each other and thus come into contact, or towards the electrically conductive means and thus come into contact.
[0016] In the release position, the sleeve does not necessarily have to be in contact with the base body. It can be sufficient, for example, to push the sleeve onto the base body after the electrical conductors have been accommodated and to bring it into the fixed position. However, it is also conceivable to connect the base body and the sleeve to each other and to change only their position relative to each other in order to go from the release position into the fixed position and back.
[0017] In order to be able to use the insulating connector even at high temperatures, the base body and the sleeve are made of a ceramic material and thus of a temperature-resistant material. Thus, the assembly can remain dimensionally stable and maintain the mechanical and electrical or insulating properties even at high temperatures. In addition to the ceramic material used for the base body and the sleeve, it is also conceivable to have a material which is rather temperature-resistant and at the same time electrically insulating, for example glass.
[0018] Furthermore, ceramic materials expand only to a low degree in the case of a temperature increase compared to metallic materials, thus ensuring a high degree of stability of the dimensions of the base body and the sleeve even at high temperatures. Conventionally, plastics with properties which deteriorate at high temperatures are used for insulation. The plastics can lose their mechanical stability due to softening, melting or embrittlement. In the case of the ceramic insulating connector, the insulating connector can remain functional even at high temperatures, for example at temperatures above 200°C or 250°C, and is not affected by heating and cooling cycles.
[0019] Advantageous embodiments and variants of the application become apparent from the dependent claims and the following description. The features cited in the dependent claims individually can be combined with each other in any technically meaningful manner and with the features presented in more detail in the following description and can represent other advantageous variants of the application.
[0020] In an advantageous embodiment of the insulating connector, the insulating connector is characterized in that the sleeve substantially surrounds the base body. In this case, the sleeve is a hollow body which can accommodate the base body in its cavity. The sleeve can have one or more openings in order to be able to insert the base body and / or to be able to lead the electrical conductors to the outside.
[0021] In the sense of the present application, a sleeve which substantially surrounds the base body means that parts of the base body can protrude from the sleeve and it is not necessary that all sides of the base body are covered by the sleeve.
[0022] In particular, the sleeve can have a substantially cylindrical shape with an opening for accommodating the base body. Preferably, the sleeve has a tubular shape in this case. In the present application, a substantially cylindrical shape means the cylindrical basic shape of the sleeve, which is adapted to the function of the sleeve by design adjustments, such as holes, cutouts or thickened portions. The basic shape or basic area of the sleeve is in particular circular or rectangular.
[0023] A tubular shape is particularly advantageous if the base body also has a cylindrical shape. Thus, the electrical conductor can be laid along the cylindrical housing surface of the base body and the sleeve can be pushed onto the base body and in the process fix the electrical conductor on the base body.
[0024] Especially in this embodiment, it is advantageous if the sleeve and the base body are adapted to each other in such a way that a rotation of the sleeve and the base body relative to each other is prevented, preferably in a fixed position, by a molded portion on the sleeve and a corresponding cutout on the base body or by the opposite arrangement. This can also be achieved by a rectangular geometry of the sleeve and the base body.
[0025] Preferably, the sleeve and the base body are adapted to each other in such a way that the sleeve can be pushed onto the base body and in particular is configured to be able to be pushed onto the base body along the electrical conductor. In this case, "along the electrical conductor" means the elongated structural shape of the electrical conductor, for example a cable, a strand, a wire, a pin or a conductor path, wherein the sleeve should be pushed along the longitudinal axis of the electrical conductor. The longitudinal axis of the electrical conductor extends along the electrical conductor and thus along the flow direction of the electrical current through the electrical conductor.
[0026] In the case of this structural shape, it is advantageous if the electrical conductor is guided outwards through an opening in the sleeve. Thus, the sleeve has in particular at least one opening which can be used for inserting the electrical conductor.
[0027] In one embodiment of the insulating connector, the base body and the sleeve can be coupled to each other by a fixing element in the fixed position of the sleeve. With the fixing element, the sleeve is prevented from being unintentionally moved from the fixed position into the released position, thus preventing the electrical conductor from being unintentionally detached.
[0028] Such a fixing element can be configured as a hook connection, but can also be realized by a forced fit of a spring element, a clevis, a pin, a split pin or a wire holder and by a threaded connection. Preferably, the base body and the sleeve are connected to each other by a forced fit of the fixing element. This connection allows the sleeve and the base body to be connected very simply and quickly and is usually able to be connected and disconnected without the use of any tools.
[0029] Since both the base body and the sleeve are made of ceramic, it is advantageous if the fixing element is made of a more flexible material, for example a metal.
[0030] The fixing can have an actuation area, which, when actuated, uncouples the effect. Thus, the base body and the sleeve can be decoupled from each other again.
[0031] The fixing can also be realized by, for example, a pin, a wire or a clamp, which extends into a cutout in the base body and the sleeve and thus forces the base body and the sleeve to be connected to each other. Such a wire is simple to manufacture and cost-effective, but still reliably fulfills its task.
[0032] In particular, the fixing is configured as a wire holder and has two legs, which can be elastically separated and spring back together. If the two legs are separated by a spreading force or elastically, they spring back as soon as the spreading force decreases. In particular, a fixing portion extending inwardly or outwardly perpendicular to the legs is formed at the free end of the legs. In particular, the legs serve to reach behind the base body or the sleeve in the fixing position.
[0033] In another embodiment of the insulation connector, the fixing can be detached without tools, so that the sleeve can be brought into the release position or the fixing position. When the sleeve is in the release position, the base body and the sleeve can be decoupled from each other.
[0034] In this context, "without tools" means that the user does not need additional tools to detach the fixing. For example, an actuation area or a button can be provided, which can be actuated with the fingers.
[0035] In this case, the fixing can be detached directly or indirectly, for example via a joystick. When the fixing is detached, the sleeve can be brought from the fixing position into the release position and vice versa. If the fixing is not detached, the sleeve is fixed in the fixing position.
[0036] In another embodiment of the insulation connector, the base body has electrical connections for contacting the electrical conductors. Since a direct connection of the electrical conductors to each other is not mandatory, one option is to contact them via the electrical connections. Thus, an electrical contact connection with defined boundary conditions is established by the connections.
[0037] Alternatively, the two electrical conductors can already be connected with the connections and placed in the base body in the connected state. For this purpose, the base body has matching cutouts, as described below.
[0038] The electrical connections described above are usually made of metal. The electrical conductors to be contacted are brought into contact with the electrical connections, so that electrical energy can flow from one conductor into the other conductor via the connections.
[0039] The connections can be conventional crimps. The connections are then wrapped around the stranded wires of the two conductors arranged side by side, which have had their insulation removed, and are then crimped or deformed. In particular, the connections are shaped as a square.
[0040] Depending on the configuration of the electrical connection, the removal of the insulation of the electrical conductor in the contact area can be omitted. To this end, blades or extrusion areas can be provided in the electrical connection, which open the insulation of the electrical conductor and come into contact with the electrically conductive core of the electrical conductor when the electrical conductor is inserted.
[0041] The electrical connection can assume other tasks, for example the securing of the electrical conductor by clamping it in the electrical connection. It is also conceivable that the sleeve cooperates with the electrical connection and the electrical conductor is clamped in the electrical connection and thus only electrically contacted in the fixed position of the sleeve.
[0042] Thus, in one variant, the insulation connector can be configured such that the electrical connection electrically contacts the electrical conductor as a result of the sleeve being pushed onto the base body. For example, the electrical conductor can be pushed towards the electrical connection by pushing the sleeve, thereby establishing electrical contact with the connection. It is also conceivable that the electrical conductor is pressed into the aforementioned blades or extrusions by pushing the sleeve.
[0043] It is also conceivable that the electrical conductor is contacted by a solder connection, preferably by a solder joint.
[0044] In another embodiment of the insulation connector, the base body has a substantially cylindrical shape. In the present application, substantially cylindrical means the substantially cylindrical basic shape of the base body, which is adapted to the function of the base body by design adjustments, for example drillings, cutouts or thickened portions. Alternatively, the base body can have a cuboid shape.
[0045] In particular, the base body has cutouts, which are provided in the outer shell surface or the cylindrical outer shell surface of the base body. Thus, the electrical conductors can be arranged equidistantly on the circumference of the jacket surface or the cylindrical jacket surface around the base body and thus have the maximum possible distance from one another. Thus, it is ensured that the electrical conductors are contacted only in the intended position.
[0046] The electrical conductors can be connected to one another by at least one connection. Thus, it is advantageous to provide cutouts in the base body for these connections, since an electrical contact connection with defined boundary conditions can be established by the connections. In particular, the cutouts are dimensioned such that pairs of connected electrical conductors can be accommodated in the cutouts, in particular also the connections.
[0047] When the electrical conductors are electrically and mechanically connected to one another by the connections, then in particular the connections are arranged in the cutouts of the base body, thereby preventing the electrical conductors from sliding out of the base body in the longitudinal direction.
[0048] In particular, each cutout has two stops which are arranged on the sides of the connecting piece in the longitudinal direction of the electrical conductors to be connected. If the electrical conductors are moved in the longitudinal direction, the connecting piece abuts against the respective stop. The stops achieve a forced fixing of the two electrical conductors connected with one connecting piece.
[0049] Each stop has a slot or opening through which the conductor, in particular the strand, can pass through the stop.
[0050] The connecting piece can have a larger size than the electrical conductors, in particular a larger diameter, so that the cutouts can be configured in such a way that the connecting piece can be placed into the cutout through the large openings of the cutout, while the electrical conductors can be guided through the small openings of the cutout, through which the connecting piece cannot pass due to the larger size. The larger openings are then closed by the sleeve in the fixed position so that the connecting piece can no longer leave the cutout.
[0051] In this case, "slipping out of the base body in the longitudinal direction" means that the electrical conductors are fixed on the base body in such a direction in which the sleeve is also pushed onto the base body, i.e. along the electrical conductors themselves.
[0052] The connecting piece can be a crimp connector, a press-in connector or a screw connector, but also be formed by a soldering tin for a soldered connection. In this case it is important that the connecting piece and in the specific case the soldering part realized with the soldering tin has a larger size than the electrical conductors, which has a diameter at the connection point which is larger than the diameter of the electrical conductors, for example.
[0053] If the electrical conductors are connected by means of a splice connection, the connecting piece can also be formed by the electrical conductors themselves. In a splice connection, the electrical conductors or their individual strands are intertwined and / or knotted at the splice point so that the electrical conductors are mechanically and electrically connected to one another. The splice point is usually thicker than the electrical conductors themselves.
[0054] Also in the case of this connection technology, it is important that the connecting piece and in the specific case the splice point of the splice connection with the intertwined or knotted electrical conductors has a larger size than the individual electrical conductors, for example a diameter at the splice point which is larger than the diameter of the individual electrical conductors.
[0055] The connecting piece can be configured from metal and designed as a sleeve, a clamping band, a conductor path, etc. In this case, the cutouts are arranged in such a way that the connecting pieces do not come into contact with one another when not intended to do so. For this purpose, for example, a partition of the ceramic material of the base body remains between the cutouts of the connecting pieces.
[0056] In another embodiment of the insulating connector with at least two electrical conductors, the base body is configured such that the non-contacting electrical conductors are arranged spatially separated from one another. Preferably, the electrical conductors are arranged spatially separated from one another by a separation, in particular by a ceramic structure on the base body. This spatial separation can be achieved by structures in the form of ceramic partitions, for example, which extend between the electrical conductors extending parallel to one another. Due to these structures, a reliable electrical insulation of the non-contacting electrical conductors is ensured, even in the event of, for example, a loosening of the electrical conductors.
[0057] In another embodiment of the insulating connector with at least two electrical conductors, the electrical conductors have end faces at one end, which, in the case of contacting electrical conductors, are arranged opposite one another in the base body. Such end faces are formed, for example, as a result of cutting the electrical conductors in the form of electrical cables to a certain length. In this case, the cut end of the metal core of the electrical cable forms the end face.
[0058] In particular, the insulating connector can accommodate the electrical conductors to be contacted such that the two end faces of the electrical conductors are opposite one another. Thus, a space-saving solution for contacting the electrical conductors is created, since the electrical conductors are arranged in an aligned manner as if the electrical conductors had not been cut through at all.
[0059] The application also relates to an assembly formed by assembling at least two electrical conductors in an insulating connector, in particular an insulating connector as described above. To this end, the electrical conductors are arranged in a ceramic base body and a ceramic sleeve surrounding the base body, such that in a fixed position of the sleeve, the electrical conductors are fixed in the ceramic base body. In particular, a pair of electrical conductors is fixed in the longitudinal direction and in the radial direction of the electrical conductors, respectively.
[0060] In particular, the two electrical conductors are electrically and mechanically connected by a connecting piece, wherein the connecting piece has a greater diameter than the respective other part of the electrical conductors. The connecting piece is arranged in a cutout of the base body, such that the electrical conductors are fixed in the base body in the longitudinal direction. In particular, two stoppers are formed in the cutout, which are arranged on one side of the connecting piece, respectively, when viewed in the longitudinal direction. The cutout has a slot or an opening for guiding the electrical conductors through. The slot is open on one side, respectively, when viewed in the radial direction, i.e. the electrical conductors as well as the connecting piece can be inserted into the base body in the radial direction in the already connected state. The cutout is radially sealed on the outside by the sleeve and the electrical conductors are thus also fixed in the radial direction.
[0061] In particular, the assembly also comprises a fixing piece which fixedly connects the base body and the sleeve to one another.
[0062] Alternatively, the electrical conductors can be contacted directly via the end faces; however, they can also be electrically contacted at different positions and, depending on the embodiment, via additional connecting pieces.
[0063] In another embodiment of the insulation connector with at least two electrical conductors, the electrical conductors are arranged parallel to each other within the base body. In this context, parallel means that the imaginary central axes of the electrical conductors, for example along the course of the individual conductors, are essentially parallel to each other. Due to the parallel arrangement of the electrical conductors, the electrical conductors can be arranged in a space-saving manner and the insulation connector can be constructed accordingly in a space-saving manner.
[0064] It is also conceivable that the central axes of the individual electrical conductors are arranged at an angle, wherein the central axes follow the course of the electrical conductors. Depending on the application, it is an option to arrange the electrical conductors to be contacted at 90°.
[0065] In another embodiment of the insulation connector with at least two electrical conductors, the electrical conductors have an insulation layer, which is removed in the contact area of the electrical conductors. In order to better contact the electrical conductors, it can be advantageous that the electrical conductors, which are usually insulated over their entire length, are free of the insulation layer in the contact area within the insulation connector. To this end, the insulation layer is removed from the end of the electrical conductors over a length of usually 5 to 15 times the metal diameter for the contact. BRIEF DESCRIPTION OF DRAWINGS

[0079] Figure 1 An embodiment of an insulated connector 1 for contacting four conductor pairs consisting of eight electrical conductors 2 is shown. The insulated connector 1 has a base body 3, a sleeve 4 and a fixing 5.
[0080] Among the eight electrical conductors 2, every two electrical conductors 2 are in electrical contact with each other. For this purpose, the contacting electrical conductors 2 are inserted into the insulated connector 1 in opposite fashion, respectively.
[0081] The base body 3 is made of a ceramic material and accommodates the contacting electrical conductors 2 in cutouts 6, respectively (in this regard, see Figure 4 ), such that the non-contacting electrical conductors 2 are spatially separated from each other and thus electrically insulated, since the ceramic material of the base body 3 is not electrically conductive.
[0082] In order to hold the electrical conductors 2 in their position, they are fixed in the cutouts 6 by means of the ceramic sleeve 4. For this purpose, the sleeve 4 is pushed onto the base body 3 along the electrical conductors 2. In the process, the electrical conductors 2 are clamped in notches 9 and thus fixed on the base body 3. The notches 9 can be seen in Figure 4 .
[0083] In order to hold the sleeve 4 in its position relative to the base body 3, a fixing 5 in the form of a clamp is provided. By snapping the fixing 5 into a corresponding cutout 7 in the sleeve 4 and into the base body 3 and behind the sleeve 4, the fixing 5 forcibly connects the sleeve 4 with the base body 3. The fixing 5 is configured in a similar snap-in connection. Thus, the connection can be released again by moving the fixing 5, so that the sleeve 4 and the base body 3 can be separated from each other.
[0084] Figure 2 An embodiment of the insulation connector 1 in Figure 1 is shown from a different perspective. In this illustration, the fastening 5 is easily recognizable. The fastening comprises a shaped wire which is located in a cutout 7 of the sleeve 4. By pushing the part of the fastening 5 which protrudes from the sleeve 4, the fastening 5 can be disengaged again and the sleeve 4 can be pushed off the base body 3. Thus, the electrical conductor 2 is exposed and can be removed from the insulation connector 1 again.
[0085] Figure 3 An embodiment of the insulation connector 1 in Figure 1 and 2 is shown from a view on the base body 3 inside the insulation connector 1 without the sleeve 4. In order to separate the base body 3 and the sleeve 4, the fastening 5 is removed from the insulation connector 1. The base body 3 has through-holes 8 for accommodating the fastening 5. Thus, in the latching state, the fastening 5 can extend into the sleeve 4 on both sides of the base body 3 and forcibly connect the two components to each other.
[0086] The cutouts 6 for accommodating the electrical conductors 2 are easily recognizable. In the cutouts 6, the electrical conductors 2 are mechanically and electrically connected in pairs, respectively, with the connecting pieces 13.
[0087] Between the cutouts 6, partitions of the ceramic material of the base body 3 remain, so that the contacting pairs of electrical conductors 2 are insulated from each other.
[0088] Figure 4 An embodiment of the insulation connector 1 in Figure 1 is shown from a view on the base body 3. The electrical contacting connection of the electrical conductors 2 is realized by the connecting pieces 13 (see Figure 2 ). The connecting pieces 13 are configured as crimp connectors with a diameter which is larger than the diameter of the electrical conductors 2. The connecting pieces 13 are arranged in the cutouts 6. Stop pieces 14 are provided in the cutouts 6. In this case, the stop pieces 14 are provided on the side of the connecting pieces 13, respectively. The stop pieces 14 have notches 9. In this case, the notches 9 are configured to be smaller than the dimension of the connecting pieces 13 and larger than the diameter of the electrical conductors 2. In this way, the connecting pieces 13 cannot slide out of the base body 3 in the direction of the electrical conductors 2. The electrical conductors 2 or only the strands of the electrical conductors 2 extend through the notches 9.
[0089] When the sleeve 4 is pushed onto the base body 3, the cutouts 6 are closed by the sleeve 4, so that the connecting pieces 13 are fixed in their position together with the electrical conductors 2 and cannot slide out of the base body 3 laterally or in the radial direction of the electrical conductors 2.
[0090] Figure 5 An embodiment of the insulation connector 1 in Figure 1The sleeve 4 of the embodiment of the insulation connector 1. The sleeve 4 is configured substantially cylindrical or tube-shaped and is integrally connected on one side to the cover 10. The cover 10 has four passages 11 for guiding the electrical conductors 2 therethrough. The side of the sleeve 4 opposite the cover 10 is configured open for accommodating the base body 3.
[0091] The cutouts 7 for the fasteners 5 are arranged opposite in the housing surface of the sleeve 4. The cutouts 7 are configured such that the fasteners 5 can be pushed from the outside through the sleeve 4 and through the through-holes 8 of the base body 3 and into the cutouts 7 on both sides of the sleeve 4.
[0092] Figure 6 A sectional view of the embodiment of the insulation connector 1 is shown, wherein the sleeve 4 is in the release position. The sleeve 4 can be brought into the release position, in which the base body 3 and the sleeve 4 are not connected to each other. In the release position, the electrical conductors 2 can first be placed in the base body 3 and not be completely fixed. Rather, by being placed in the base body 3, the electrical conductors 2 are loosely guided such that they can finally reach the completely correct position when the sleeve 4 is pushed. Figure 1 In the release position, the fastening positions 5 are also not engaged with the sleeve 4 or the base body 3. Thus, in the release position, the sleeve 4 and the base body 3 can be moved freely relative to each other.
[0093] In this illustration, the parallel arrangement of the electrical conductors 2 is illustrated by the drawn central axes 12. The central axes 12 of the electrical conductors 2 to be contacted coincide such that the electrical conductors 2 to be contacted are arranged in alignment with each other.
[0094]
[0095] A sectional view of the embodiment of the insulation connector 1 is shown, wherein the sleeve 4 is in the release position. The sleeve 4 can be brought into the release position, in which the base body 3 and the sleeve 4 are not connected to each other. In the release position, the electrical conductors 2 can first be placed in the base body 3 and not be completely fixed. Rather, by being placed in the base body 3, the electrical conductors 2 are loosely guided such that they can finally reach the completely correct position when the sleeve 4 is pushed. Figure 7 Figure 1 A sectional view of the embodiment of the insulation connector 1 is shown, wherein the sleeve 4 is in the release position. The sleeve 4 can be brought into the release position, in which the base body 3 and the sleeve 4 are not connected to each other. In the release position, the electrical conductors 2 can first be placed in the base body 3 and not be completely fixed. Rather, by being placed in the base body 3, the electrical conductors 2 are loosely guided such that they can finally reach the completely correct position when the sleeve 4 is pushed.
[0096] In the release position, the fastening positions 5 are also not engaged with the sleeve 4 or the base body 3. Thus, in the release position, the sleeve 4 and the base body 3 can be moved freely relative to each other.
[0097] In order to prevent the sleeve 4 from unintentionally leaving the fixed position and releasing the electrical conductors 2 again, the fasteners 5 are pushed in, thereby forcibly connecting the sleeve 4 with the base body 3. In this process, the fasteners 5 are pushed through the cutouts 7 of the sleeve 4 and the through-holes 8 of the base body 3.
[0098] In the following, a second embodiment of the insulation connector 1 is described. Figure 8 to Figure 11 A sectional view of the embodiment of the insulation connector 1 is shown, wherein the sleeve 4 is in the release position. The sleeve 4 can be brought into the release position, in which the base body 3 and the sleeve 4 are not connected to each other. In the release position, the electrical conductors 2 can first be placed in the base body 3 and not be completely fixed. Rather, by being placed in the base body 3, the electrical conductors 2 are loosely guided such that they can finally reach the completely correct position when the sleeve 4 is pushed.
[0099] Here, the insulation connector 1 is designed for contacting four electrical conductors 2, i.e. for contacting two pairs of electrical conductors 2, respectively.
[0100] Here, the insulating connector 1 also has a base 3. The base 3 is formed of a ceramic material. Here, the base 3 has a cuboid construction and, in this case, a basically rectangular cross-section. The base 3 is surrounded by a sleeve 4, and the base 3 and the sleeve 4 are forcibly connected in a fixed position by a fastener 5 (see [link to documentation]). Figure 8 ).
[0101] like Figure 9 and 11 As shown, the substrate 3 has two spaced-apart cuts 6, in which a pair of electrical conductors 2 are arranged. In the present case, the two electrical conductors 2 are respectively connected (crimped) to the connector 13. For this purpose, the insulation layer 15 of the electrical conductors 2 to be connected is removed from the ends of the electrical conductors 2 to expose the stranded wires 16. The exposed stranded wires 16 are surrounded by the connector 13.
[0102] To prevent the electrical conductor 2 from being removed from the insulating connector 1 in the longitudinal direction, two spaced-apart stops 14 are formed in the cutout 6. The stops 14 are spaced apart such that a connector 13 is arranged between the stops 14, and the connector 13 is forcibly restrained by the stops 14 in the transverse direction (i.e., in the longitudinal direction of the electrical conductor 2). The stops 14 have slots 9 through which the electrical conductor 2 or stranded wire 16 passes. In this case, the stops 14 are configured as material septa protruding into the cutout 3.
[0103] Here, cut 6 is open on the side (see...). Figure 9 This allows a pair of electrical conductors 2, which are already connected to connector 13, to be placed laterally in the cutout 3 in the radial direction.
[0104] In addition to the base 3, the insulating connector 1 also includes a ceramic sleeve 4, which surrounds the base 3 and can be pushed onto the base 3. The sleeve 4 is constructed similarly to... Figures 1 to 7 In the first embodiment described herein, the cover 10 has two openings 26 for the passage of the electrical conductor 2 (see [reference]). Figure 11 The sleeve 3 is used to forcibly fix the electrical conductor 2 in the base 3 in the radial direction.
[0105] The fastener 5 is used to connect the base 3 and the sleeve 4 to each other. Here, the fastener 5 is constructed as a type of wire frame with two legs 17, which can be elastically moved or extended toward or away from each other (see...). Figure 9 (Double-headed arrow in the image). The end of the leg 17 has a curved fixing portion 18, which extends perpendicularly to the leg 17.
[0106] In this second embodiment, in the fixed position, the fastener 5 is arranged along the outer side of the sleeve 4 (and the base 3). In the fixed position (see...) Figure 10 The fastener 5 abuts against the groove-shaped protrusion 19 on the sleeve 4 on one side (see...). Figure 10 and 11 Furthermore, the fixing portion 18 on the leg 17 of the fastener 5 extends to the rear of the base 3. For this purpose, the base 3 has a recess 20 into which the fixing portion 18 of the leg 17 extends.
[0107] To protect the fastener 5, the sleeve 4 has a groove 21 that is parallel to and extends between the electrical conductors 2, and the leg 17 of the fastener 5 is accommodated in the groove.
[0108] For mounting the fastener 5, the sleeve 4 has an inclined portion 22 on each side. When the fastener 5 is inserted, the two legs 17 are guided along the inclined portion 22 by the fixing portion 18 and pushed open by the inclined portion 22, and in the fixed position, the legs 17 are engaged in the recess 20 behind the base 3 by the fixing portion 18.
[0109] In the region where the conductor 2 enters the insertion port 25 of the substrate 3, the substrate 3 has a thickened portion 24 (see [reference]). Figure 9 ).
