Definitions
- a connector is described with a one-piece insulating body for receiving contact inserts, which are connected to electrical conductors.
- the insulating body is for this purpose formed with a receiving area for receiving at least one substantially cylindrical contact insert, the contact insert at a first end a contact portion for electrical connection with a gegentician shaped contact piece of the connector, at a second end an insertion opening with a central longitudinal axis for receiving a conductor , A clamping device and a connecting portion for mechanical connection of the contact portion having the insulating body.
- the clamping device is arranged such that an actuation of the clamping device for releasable and reconnectable fastening of the male conductor takes place from a direction transverse to the central longitudinal axis, wherein the clamping device comprises either a clamping screw or a screwless clamping element.
- Such electrical connectors are particularly suitable for use with higher voltages and / or currents (rated voltage: up to 600 V and more (about 1000 V), rated current: up to 16 A and more (about 80 A)), e.g. used for electrical equipment in mechanical engineering, electrical cabinets, light and sound cabling, or the like.
- the receiving area of the insulating body is adapted to the type of clamping device over which the contact insert to be used has.
- the clamping device comprises a clamping screw or a screwless clamping element
- the insulating body has a different shape.
- the clamping device is designed as a clamping screw
- it is additionally secured in the receiving region of the insulating body via a further insulating body, which is designed as a lid. This is for example latched, pressed, glued or fixed by welding.
- Another way to secure the clamping screw is to introduce them into a one-piece insulating body.
- the conductor is inserted from the same side from which the clamping element is actuated by means of an actuating tool. Accordingly, the actuating direction is substantially identical to the central longitudinal axis of the insertion opening for receiving a conductor.
- an object is to make the production of connectors cost and at the same time to ensure a reliable electrical connector.
- the insulating body has at least one stop to cooperate with a arranged on the connecting portion locking element for securing the contact insert, and at least one recess in its receiving area, which is dimensioned so that both the Insert clamping screw into the recess and the screwless clamping element is accessible through the recess from the outside.
- the contact insert is secured within the insulator against being pulled against the insertion direction, without the need for further Isolier analysesmaschine, such as lids or the like., would be necessary or that the fuse of the contact insert must be made in a one-piece insulator by means of a clamping screw.
- the recess in the receiving area of the insulating body further ensures that the insulating body can be used regardless of whether a contact insert with a clamping screw or with a screwless clamping element is to be received therein.
- a (based on these two possible embodiments of the clamping device) "universal" insulating body is provided.
- the contact insert can be inserted into the insulating body regardless of whether the clamping device used comprises a clamping screw or a screwless clamping element. In that an actuation of the clamping device both in the case of a clamping screw and in the case of a screwless clamping element in the inserted state of the contact insert is still possible, a conductor can be attached at any time releasably and reconnectable with the clamping device within the insertion of the contact insert.
- the latching element is designed to be resilient in order to allow movement of the contact insert in an insertion direction and to rest with an active surface in a direction opposite to the direction of insertion against the stop.
- the locking element may comprise a resilient latching hook, which is integrally connected to the contact insert. Due to the integral design, the number of parts used and in this way the assembly times are reduced.
- the at least one recess of the insulating body is bounded on two opposite sides by webs which are essentially parallel to one another and are oriented coaxially with respect to the actuating direction.
- the webs are dimensioned such that on the one hand they do not obstruct actuation of the clamping device by means of an actuating tool and on the other hand can touch a clamping screw to be introduced into the recess on the peripheral surface of its screw head or screw shank.
- the webs are wedge-shaped and include in the direction of actuation of an increasingly smaller clear width between the mutually facing flanks.
- the webs may each have a contact surface on the facing flanks.
- the contact surfaces can also be concave in the direction of actuation and increasingly larger.
- the clamping device used of the contact insert comprises a clamping screw. This is screwed from the outside into an internal thread of a screw hole, which is attached to the contact insert and aligned with the receptacle of the insulating body to act on a conductor located in the insertion opening (possibly with the interposition of a conductor protection).
- the conductor is shakeproof in the insertion and clamp with minimum electrical contact resistance.
- the concave curved surfaces of the webs may have a radius of curvature which substantially corresponds to the radius of the screw head or the screw shaft.
- the contact surfaces do not increase or increase in a direction opposite to the actuating direction increasingly.
- the contact surfaces a z .B. have friction-increasing embossing. Such an embossing further strengthens the mechanical resistance and thus the securing effect.
- At least one web may have at least one bore substantially coaxial with the direction of actuation and the shape of which gives the web a compliance relative to a clamping screw, the degree of compliance being determined by the shape of the bore.
- the bore of the web can be dimensioned differently large, both in terms of their depth and their diameter.
- the bore may have different cross sections, z. B. a circular or elliptical cross-section.
- the recess is formed open against the insertion direction to allow insertion of the contact insert with preassembled clamping device in the insulating body.
- the recess has an opening in the direction opposite to the insertion direction, which is large enough to introduce a pre-assembled on a contact insert clamping screw. This simplifies in particular the assembly of the connector, since the contact insert and the preassembled clamping device can be introduced as an assembly in the insulating body.
- the contact insert in the region of the insertion opening has a contact inner surface for the conductor, against which the conductor is pressed by the clamping device and which has a macroscopic surface structure to increase the number of contact points of the conductor with the contact insert.
- the macroscopic surface structure in one of the central longitudinal axis containing sectional view have a sawtooth-like profile, the tips of which point away from the insertion opening.
- the sawtooth profile produces a directional mechanical resistance, similar to a barb, that does not significantly affect the movement of the conductor in one direction (insertion) while making it difficult to move in the opposite direction (withdrawal). This is achieved by the fact that the profile with its opposite movement of the tips increases the necessary extraction force of the conductor.
- the contact insert may have an engagement region in which at least one positive connection point for forming the cylindrical contact insert is arranged.
- a cylindrical contact insert can be produced from a substantially planar base material by providing an engagement formation, for example a bulge, and a corresponding receiving formation, for example a recess, for producing a positive connection at two outer edges of the planar base material to be joined.
- the contact insert has at least one support surface for resting on at least one corresponding bearing surface in the insulating body.
- the support surface allows on the one hand a positionally accurate introduction of the contact insert in the insulating body and limits the other hand, the insertion depth of the contact insert in the insulating body.
- the contact insert has a conductor protection, which is integrally connected to the contact insert.
- the conductor protection protrudes from the contact insert in the region of the insertion opening and is formed in a bending region with such a bend that it extends into the insertion opening.
- the conductor protection have an embossing in its bending region, which allows a defined suspension of the conductor protection.
- Such a conductor protection is particularly advantageous if the clamping device has a clamping screw, which would be in direct contact with the inserted conductor without conductor protection and possibly damage it.
- such a conductor protection is always designed as a separate part, which must be additionally introduced and secured in the contact insert.
- the integral design of the conductor protection makes an additional fuse superfluous without restricting the functionality of the conductor protection.
- the clamping device may comprise a screwless clamping element in the form of a clamping spring which can be actuated by an opening arranged on the contact insert by means of an actuating tool.
- the clamping spring in a sectional view containing the central longitudinal axis has a substantially V-shaped cross section with two legs, which are movable relative to each other due to elastic deformation.
- the clamping spring may have a clamping leg to clamp the conductor against the contact insert, and a support leg for supporting the clamping spring on the contact insert.
- the clamping spring can be used as a separate part in the contact insert or integrally formed connected to the contact insert.
- the clamping spring may further comprise at its clamping leg a receptacle for the actuating tool.
- This receptacle can be formed for example by a recess and / or a bent portion of the clamping leg.
- the conductor is inserted into the insertion opening so far that the clamping leg - as soon as it is no longer held under tension with the actuating tool - presses the conductor against the contact surface in the region of the insertion opening and fastened in this way.
- the opening on the contact insert is adapted in shape to the arrangement of the clamping spring in the contact insert, so that it provides at least one stop for supporting the actuating tool. As a result, in particular the handling of the actuating tool is facilitated.
- the contact insert is designed to be made of a flat sheet by punching and bending.
- the contact insert is structurally designed such that it can be punched out as a whole from a flat sheet metal and formed by bending individual parts to the cylindrical contact element. This allows a more cost-effective production compared to the common machining processes, such as turning the contact insert, and further reduces the production costs.
- Fig. 1 shows a schematic isometric view of a connector 10.
- the connector 10 has an insulating body 14 with two rows parallel to each other arranged electrical contact inserts 12. It is understood that in the insulating body 14 depending on the configuration of the connector 10 two, four, six, ten, sixteen, twenty-four, thirty-two, forty-eight, or up to two hundred sixteen and more contact inserts may be arranged in two or more substantially parallel rows.
- Fig. 2 shows fragmentary (according to detail II in Fig. 1 ) The typical installation situation of a first contact insert 12 in an insulating body 14 of the connector 10.
- the contact insert 12 is provided in this first embodiment with a clamping device comprising a clamping screw 16.
- the webs 48 will be described below with respect to their function and geometry with reference to the Fig. 7 described in more detail.
- Fig. 3 shows a schematic perspective view of a first contact insert 12 of a connector 10.
- the contact insert 12 is substantially cylindrical and comprises at a first end a contact portion 18 for electrical connection with a diametrically shaped contact piece of the connector 10 and at its opposite second end frontally an insertion 20 with a central longitudinal axis L for receiving a conductor (not shown).
- the insertion opening 20 is designed as a hollow cylindrical hole, wherein its central longitudinal axis L is oriented substantially coaxially to the contact portion 18.
- the contact portion 18 forms with its spread ends at the first (in Fig. 3 lower) end of the contact insert 12 a socket, but it can also be designed as a pin with a closed first end (see. Fig. 9 ).
- the contact insert 12 further has a cross-sectionally substantially square connecting portion 22 which is formed by bending and by means of an engaging portion 30 and 130 (see Fig. 9 ) is held together under positive locking.
- a flat material such as a galvanized tape
- a partial galvanization of the material used can be mounted in the connection region of the conductor and in the contact section 16 either on the outer surface in the case of a contact pin or on the inner surface in the case of a contact socket. In this way, it is ensured that a good electrical connection is made possible via the contact insert 12 of conductor and connector 10.
- a hole in the form of a screw hole 24 (in Fig. 3 indicated) arranged to receive the clamping screw 16.
- This can, for example, a screw with z. B. metric thread, wherein the screw hole 24 has a corresponding metric internal thread.
- the clamping screw 16 may also have a self-tapping thread, whereby the process step of threading into the screw hole 24 of the connecting portion 22 is omitted.
- the conductor is inserted through the insertion opening 20 along the central longitudinal axis L of the insertion opening 20 (based on Fig. 3 ) inserted from above into this, so that the end face of the stripping rests on unprepared conductor, or the extension of the wire end ferrule on the upper edge of the insertion opening 20.
- an actuating tool for example, a screwdriver screwed deeper into the screw hole 24 and presses with the interposition of a conductor guard 26 the head against an inner surface of the insertion 20.
- the clamping screw 16 also directly with her screw shank the Press the conductor against the inner surface.
- the conductor protection 26 serves to protect the conductor from any damage by the clamping screw 16. As in Fig.
- the leader will be in the in Fig. 3 illustrated embodiment pressed by the clamping screw 16 and the conductor guard 26 against a contact inner surface A in the region of the insertion opening 20 which is arranged on the opposite side of the screw hole 24 in the connecting portion 22 of the contact insert 12.
- this has a macroscopic surface structure, here with a longitudinal sawtooth-like profile, the tips of which point away from the insertion opening 20 in the direction of the first end of the contact insert 12. In this case, even a slight deviation between insertion angle and exit angle is sufficient to allow such an effect as that of a barb.
- the insertion angle can be more than 50 °, while the exit angle is less than 40 °, for example.
- the introduced in the insertion opening conductor is thus secured in addition to the locking force caused by the clamping screw 16 against unwanted withdrawal from the contact insert 12.
- two locking elements 38 are formed in the form of resilient latching hook in its connection region. These are simply punched out of the flat base material with the exception of a holding web 40 and bent outwards. In this way, a second end of the contact insert 12 facing active surface 42, which can be supported on a mounted on the insulating body 14 stop 44 in a direction opposite to the insertion direction E blocking.
- the contact insert 12 is inserted in the insertion direction E in the insulating body 14 until the active surfaces 42 of the two locking elements 38 latch against the stops 44 and lock a pull-out movement by their engaged with the stops 44 active surfaces 42.
- the locking elements 38 it is possible to secure the contact insert 12 without the use of additional insulating in the insulating body 14 of the connector 10 sufficiently against unwanted extraction.
- the contact insert 12 is supported in the embodiment shown via four support surfaces 70 on corresponding bearing surfaces 72 in the insulating body 14.
- the support surfaces 70 are in this case arranged on the substantially square connecting portion 22 in the bending corners.
- the bearing surfaces 72 on the insulating body 14 are formed in that the receiving region of the insulating body 14 in the bending corners of the male contact insert 12 has a smaller cross-section than the contact insert 12.
- at least one support surface 70 of the contact insert 12 and a corresponding bearing surface 72 on the Insulating body 14 may be formed in a different area than that of the bending corners of the contact insert 12.
- Fig. 4 to 7 show different views and details of the introduced into the insulating body 14 first contact insert 12. It is in 4 and 5 the installation situation is shown both from the front as well as cut while Fig. 6 a detailed view of the mechanical latching of the contact insert 12 in the insulating body 14 represents.
- the insulating body 14 has, as Fig. 2 and 4 to 7 show recesses 46 (see. Fig. 4 ), which are sufficiently large to introduce a clamping screw 16 and to ensure accessibility of the clamping screw 16 and thus to ensure an adjustment of the screwing of the clamping screw 16 in the screw hole 24. Furthermore, each recess 46 bounded on two opposite sides by webs 48, which are arranged parallel to each other and coaxial with the actuating direction B. The webs have in an area that in the front view Fig. 4 at the same height with the cylindrical screw head 36 of the clamping screw 16 has a thickened portion 50 which has a bore 52 substantially centrally disposed. At the two side edges of the webs 48 is in this section 50 (see. Fig.
- the clamping screw 16 undergoes a mechanical resistance when inserted into the screw hole 24.
- this contact surface 54 increases in the direction of actuation B increasingly, whereby the resistance in the form of an increasing braking or clamping action when screwing the clamping screw 16 also increases. This prevents loosening or loosening of the clamping screw 16 during transport.
- contact surface A convex or to present a contact surface 54 of constant size in the direction of actuation B. It may also be useful, depending on the application, that the contact surface 54 increases in a direction opposite to the direction of actuation B.
- the concave contact surfaces 54 have a radius of curvature that substantially corresponds to the radius of the screw head 36 and thereby produce a linear contact between the screw head 36 and the webs 48, whereby the mechanical resistance is more pronounced with otherwise identical parameters than with a punctiform Contact.
- the mechanical resistance can be further enhanced by the fact that the contact surfaces 54, as in Fig. 7 to recognize, have a friction-increasing imprint. In this case, this embossment is formed by grooves extending essentially in one direction transversely to the circumferential direction of the screw head 36.
- the holes 52 on the webs 48 may be formed as through holes or blind holes with different depths. In this way, it is also possible to influence the normal force acting on the circumferential surface of the screw head 36 and thus the mechanical resistance of the clamping screw 16.
- the bores 52 may have a circular or elliptical cross-section.

- the effective direction of the clamping spring 156 is not consistent with the direction of actuation B.
- the contact inner surface A is not opposite to the opening 166, but with respect to one of the legs of the clamping spring 156, the clamping leg 158 arranged.
- the support leg 160 of the clamping spring 156 is supported with its surface facing away from the clamping leg 158 on an inner surface of the connecting portion 122, while the clamping leg 158 projects transversely from the support leg 160 in the direction of the contact surface 54 and presses against it.
- the clamping leg 158 In its end remote from the second end of the contact insert 112, the clamping leg 158 has a bending section 162, so that it is substantially J-shaped.
- the bending portion 162 oriented to the left in a "J" is disposed facing the support leg.
- a tool receiving recess 164 may be arranged in the form of an elongate opening. Both the bending portion 162 and the Malawifactaus Principleung 164 serve to receive an actuating tool (not shown), by means of which the clamping leg 158 can be moved in the direction of the support leg 160.

Description
Nachstehend wird ein Steckverbinder beschrieben mit einem einteiligen Isolierkörper zum Aufnehmen von Kontakteinsätzen, die mit elektrischen Leitern verbunden sind. Der Isolierkörper ist hierzu mit einem Aufnahmebereich zur Aufnahme wenigstens eines im wesentlichen zylinderförmigen Kontakteinsatzes ausgebildet, wobei der Kontakteinsatz an einem ersten Ende einen Kontaktabschnitt zur elektrischen Verbindung mit einem gegengleich geformten Kontaktstück des Steckverbinders, an einem zweiten Ende eine Einführöffnung mit einer Mittellängsachse zur Aufnahme eines Leiters, eine Klemmvorrichtung sowie einen Verbindungsabschnitt zur mechanischen Verbindung des Kontaktabschnitts mit dem Isolierkörper aufweist. Die Klemmvorrichtung ist derart angeordnet, dass eine Betätigung der Klemmvorrichtung zum lösbaren und wiederverbindbaren Befestigen des aufzunehmenden Leiters aus einer Richtung quer zur Mittellängsachse erfolgt, wobei die Klemmvorrichtung entweder eine Klemmschraube oder ein schraubenloses Klemmelement umfasst.Hereinafter, a connector is described with a one-piece insulating body for receiving contact inserts, which are connected to electrical conductors. The insulating body is for this purpose formed with a receiving area for receiving at least one substantially cylindrical contact insert, the contact insert at a first end a contact portion for electrical connection with a gegengleich shaped contact piece of the connector, at a second end an insertion opening with a central longitudinal axis for receiving a conductor , A clamping device and a connecting portion for mechanical connection of the contact portion having the insulating body. The clamping device is arranged such that an actuation of the clamping device for releasable and reconnectable fastening of the male conductor takes place from a direction transverse to the central longitudinal axis, wherein the clamping device comprises either a clamping screw or a screwless clamping element.
Derartige elektrische Steckverbinder werden insbesondere zum Einsatz mit höheren Spannungen und/oder Strömen (Bemessungsspannung: bis zu 600 V und mehr (etwa 1000 V), Bemessungsstrom: bis zu 16 A und mehr (etwa 80 A)) z.B. für elektrische Ausrüstungen im Maschinenbau, elektrische Schaltschränke, Licht- und Tonverkabelungen, oder dergl. verwendet.Such electrical connectors are particularly suitable for use with higher voltages and / or currents (rated voltage: up to 600 V and more (about 1000 V), rated current: up to 16 A and more (about 80 A)), e.g. used for electrical equipment in mechanical engineering, electrical cabinets, light and sound cabling, or the like.
Bei bereits bekannten Steckverbindern ist der Aufnahmebereich des Isolierkörpers angepasst an die Art der Klemmvorrichtung, über die der einzusetzende Kontakteinsatz verfügt. Somit weist der Isolierkörper in Abhängigkeit davon, ob die Klemmvorrichtung eine Klemmschraube oder ein schraubenloses Klemmelement umfasst, eine andere Form auf. Bei einigen bekannten Lösungen, bei denen die Klemmvorrichtung als Klemmschraube ausgebildet ist, wird diese in dem Aufnahmebereich des Isolierkörpers zusätzlich über einen weiteren Isolierkörper, der als Deckel ausgebildet ist, gesichert. Dieser wird beispielsweise eingerastet, eingepresst, geklebt oder durch Schweißen befestigt. Eine weitere Möglichkeit die Klemmschraube zu sichern ist, diese in einen einteiligen Isolierkörper einzubringen. Dabei ist die Richtung, aus der die Schraube mit Hilfe eines Schraubendrehers oder anderen Betätigungswerkszeugs in ein korrespondierendes Gewinde eingeschraubt wird, quer zur Mittellängsachse der Aufnahme des Leiters in dem Kontakteinsatz. Hier ist jedoch nachteilig, dass bei bekannten Lösungen eine Montage des Kontakteinsatzes mit einer vormontierten Klemmschraube nicht möglich ist.In already known connectors, the receiving area of the insulating body is adapted to the type of clamping device over which the contact insert to be used has. Thus, depending on whether the clamping device comprises a clamping screw or a screwless clamping element, the insulating body has a different shape. In some known solutions in which the clamping device is designed as a clamping screw, it is additionally secured in the receiving region of the insulating body via a further insulating body, which is designed as a lid. This is for example latched, pressed, glued or fixed by welding. Another way to secure the clamping screw is to introduce them into a one-piece insulating body. In this case, the direction from which the screw is screwed by means of a screwdriver or other Betätigungswerkszeugs in a corresponding thread, transverse to the central longitudinal axis of the recording of the conductor in the contact insert. Here, however, is disadvantageous that at known solutions mounting the contact insert with a pre-assembled clamping screw is not possible.
Bei anderen bekannten Steckverbindern, deren Kontakteinsätze eine Klemmvorrichtung haben, die ein schraubenloses Klemmelement umfasst, wird der Leiter von derselben Seite eingeführt, von welcher das Klemmelement mit Hilfe eines Betätigungswerkzeugs betätigt wird. Die Betätigungsrichtung stimmt demnach im wesentlichen mit der Mittellängsachse der Einführöffnung zur Aufnahme eines Leiters überein.In other known connectors whose contact inserts have a clamping device comprising a screwless clamping element, the conductor is inserted from the same side from which the clamping element is actuated by means of an actuating tool. Accordingly, the actuating direction is substantially identical to the central longitudinal axis of the insertion opening for receiving a conductor.
Daher besteht eine Aufgabe darin, die Herstellung von Steckverbindern kostengünstig zu gestalten und zugleich eine zuverlässige elektrische Steckverbindung zu gewährleisten.Therefore, an object is to make the production of connectors cost and at the same time to ensure a reliable electrical connector.
Dies wird bei einem Steckverbinder der eingangs genannten Art dadurch erreicht, dass der Isolierkörper wenigstens einen Anschlag aufweist, um mit einem an dem Verbindungsabschnitt angeordneten Rastelement zum Befestigen des Kontakteinsatzes zusammenzuwirken, sowie wenigstens eine Ausnehmung in seinem Aufnahmebereich, die so bemessen ist, dass sowohl die Klemmschraube in die Ausnehmung einzuführen als auch das schraubenlose Klemmelement durch die Ausnehmung von außen zugänglich ist.This is achieved in a connector of the type mentioned above in that the insulating body has at least one stop to cooperate with a arranged on the connecting portion locking element for securing the contact insert, and at least one recess in its receiving area, which is dimensioned so that both the Insert clamping screw into the recess and the screwless clamping element is accessible through the recess from the outside.
Auf diese Weise wird der Kontakteinsatz innerhalb des Isolierkörpers gegen ein Ausziehen entgegen der Einsetzrichtung gesichert, ohne dass dazu weitere Isolierkörperteile, wie Deckel oder dergl., nötig wären oder dass die Sicherung des Kontakteinsatzes in einem einteiligen Isolierkörper mittels einer Klemmschraube erfolgen muß. Die Ausnehmung in dem Aufnahmebereich des Isolierkörpers sorgt ferner dafür, dass der Isolierkörper unabhängig davon verwendet werden kann, ob ein Kontakteinsatz mit einer Klemmschraube oder mit einem schraubenlosen Klemmelement darin aufgenommen werden soll. Dadurch wird ein (bezogen auf diese zwei möglichen Ausführungsformen der Klemmvorrichtung) "universaler" Isolierkörper bereitgestellt. Dieses ist insbesondere deshalb vorteilhaft, weil bei der Herstellung die Stückzahlen der hergestellten Isolierkörper erhöht werden können, während die Lagerhaltungskosten sich durch die verringerte Variantenzahl senken lassen. Der Kontakteinsatz kann unabhängig davon, ob die verwendete Klemmvorrichtung eine Klemmschraube oder ein schraubenloses Klemmelement umfasst, in den Isolierkörper eingesteckt werden. Dadurch dass eine Betätigung der Klemmvorrichtung sowohl im Falle einer Klemmschraube als auch im Falle eines schraubenlosen Klemmelements im eingesetzten Zustand des Kontakteinsatzes weiterhin möglich ist, kann ein Leiter zu jeder Zeit lösbar und wiederverbindbar mit der Klemmvorrichtung innerhalb der Einführöffnung des Kontakteinsatzes befestigt werden.In this way, the contact insert is secured within the insulator against being pulled against the insertion direction, without the need for further Isolierkörperteile, such as lids or the like., Would be necessary or that the fuse of the contact insert must be made in a one-piece insulator by means of a clamping screw. The recess in the receiving area of the insulating body further ensures that the insulating body can be used regardless of whether a contact insert with a clamping screw or with a screwless clamping element is to be received therein. As a result, a (based on these two possible embodiments of the clamping device) "universal" insulating body is provided. This is particularly advantageous because in the production of the numbers of insulators produced can be increased, while the storage costs can be reduced by the reduced number of variants. The contact insert can be inserted into the insulating body regardless of whether the clamping device used comprises a clamping screw or a screwless clamping element. In that an actuation of the clamping device both in the case of a clamping screw and in the case of a screwless clamping element in the inserted state of the contact insert is still possible, a conductor can be attached at any time releasably and reconnectable with the clamping device within the insertion of the contact insert.
Ferner kann vorgesehen sein, dass das Rastelement federnd ausgebildet ist, um eine Bewegung des Kontakteinsatzes in eine Einsetzrichtung zu ermöglichen und sich mit einer Wirkfläche in einer der Einsetzrichtung entgegengesetzten Richtung an dem Anschlag sperrend abzustützen. Dabei kann das Rastelement einen federnden Rasthaken umfassen, der integral mit dem Kontakteinsatz verbunden ist. Durch die integrale Bauweise werden die verwendete Teilezahl und auf diese Weise die Montagezeiten verringert.Furthermore, it can be provided that the latching element is designed to be resilient in order to allow movement of the contact insert in an insertion direction and to rest with an active surface in a direction opposite to the direction of insertion against the stop. In this case, the locking element may comprise a resilient latching hook, which is integrally connected to the contact insert. Due to the integral design, the number of parts used and in this way the assembly times are reduced.
Eine andere Weiterbildung sieht vor, dass die wenigstens eine Ausnehmung des Isolierkörpers an zwei gegenüberliegenden Seiten durch im wesentlichen zueinander parallele, koaxial zu der Betätigungsrichtung orientiert angeordnete Stege begrenzt wird. Die Stege sind dabei so bemessen, dass sie einerseits eine Betätigung der Klemmvorrichtung mittels eines Betätigungswerkzeuges nicht behindern und andererseits eine in die Ausnehmung einzuführende Klemmschraube an der Umfangsfläche ihres Schraubenkopfes bzw. Schraubenschaftes berühren können. Dabei kann eine auch vorgesehen sein, dass die Stege keilförmig sind und in Betätigungsrichtung einer zunehmend geringere lichte Weite zwischen den einander zugewandten Flanken einschließen.Another embodiment provides that the at least one recess of the insulating body is bounded on two opposite sides by webs which are essentially parallel to one another and are oriented coaxially with respect to the actuating direction. The webs are dimensioned such that on the one hand they do not obstruct actuation of the clamping device by means of an actuating tool and on the other hand can touch a clamping screw to be introduced into the recess on the peripheral surface of its screw head or screw shank. It can also be provided that the webs are wedge-shaped and include in the direction of actuation of an increasingly smaller clear width between the mutually facing flanks.
Ferner können die Stege an den sich zugewandten Flanken jeweils eine Kontaktfläche aufweisen. Die Kontaktflächen können zudem in Betätigungsrichtung konkav geformt sein und sich zunehmend vergrößern.Furthermore, the webs may each have a contact surface on the facing flanks. The contact surfaces can also be concave in the direction of actuation and increasingly larger.
Diese Ausführungsform des Isolierkörpers ist besonders vorteilhaft, wenn die verwendete Klemmvorrichtung des Kontakteinsatzes eine Klemmschraube umfasst. Diese wird von außen in ein Innengewinde eines Schraublochs eingeschraubt, welches an dem Kontakteinsatz angebracht ist und mit der Aufnahme des Isolierkörpers fluchtet, um auf einen in der Einführöffnung befindlichen Leiter (ggf. unter Zwischenlage eines Leiterschutzes) zu wirken. Damit ist der Leiter in der Einführöffnung rüttelsicher und mit minimalem elektrischem Übergangswiderstand festzuklemmen. Die konkav gekrümmten Flächen der Stege können einen Krümmungsradius haben, der im wesentlichen dem Radius des Schraubenkopfes bzw. des Schraubenschaftes entspricht. Dadurch wird ein linienförmiger Kontakt zwischen den konkav geformten Kontaktflächen und der äußeren Umfangsfläche ihres Schraubenkopfes bzw. ihres Schraubenschaftes hergestellt und die Klemmschraube erfährt in diesem Bereich einen mechanischen Widerstand, der ein Brems(dreh)moment oder ein Widerstands(dreh)moment sein kann. Dieser nimmt zu, wenn die Klemmschraube tiefer eingeschraubt ist. Dies wird durch eine zunehmende Vergrößerung der Kontaktflächen in Richtung der Betätigungsrichtung erreicht. So wird auf den Schraubenkopf bzw. Schraubenschaft eine sich verändernde, nämlich zunehmende Klemm- oder Haltewirkung ausgeübt, wenn die Klemmschraube in die Aufnahme eingebracht und dann in dem Innengewinde des Schraublochs eingeschraubt wird. Dieser mechanische Widerstand sichert einerseits die eingeschraubte Klemmschraube zusätzlich gegen ein Lockern oder Lösen. Andererseits kann das auftretende Widerstandsdrehmoment bei automatisierten Montageprozessen der Klemmschraube gemessen und als Referenz für die Einschraubtiefe genutzt werden.This embodiment of the insulating body is particularly advantageous if the clamping device used of the contact insert comprises a clamping screw. This is screwed from the outside into an internal thread of a screw hole, which is attached to the contact insert and aligned with the receptacle of the insulating body to act on a conductor located in the insertion opening (possibly with the interposition of a conductor protection). Thus, the conductor is shakeproof in the insertion and clamp with minimum electrical contact resistance. The concave curved surfaces of the webs may have a radius of curvature which substantially corresponds to the radius of the screw head or the screw shaft. As a result, a line-shaped contact between the concave contact surfaces and the outer peripheral surface of their screw head or their screw shaft is made and the clamping screw experiences in this area a mechanical resistance, a brake (rotary) torque or a resistance (rotary) moment can be. This increases when the clamping screw is screwed deeper. This is achieved by an increasing enlargement of the contact surfaces in the direction of the actuation direction. Thus, a changing, namely increasing clamping or holding action is exerted on the screw head or screw shaft when the clamping screw is inserted into the receptacle and then screwed into the internal thread of the screw hole. This mechanical resistance on the one hand secures the screwed-in clamping screw additionally against loosening or loosening. On the other hand, the occurring resistance torque can be measured in automated assembly processes of the clamping screw and used as a reference for the screwing.
Alternativ kann auch vorgesehen sein, dass die Kontaktflächen sich nicht oder in einer Richtung entgegengesetzt der Betätigungsrichtung zunehmend vergrößern. Bei einer Weiterbildung kann ferner vorgesehen sein, dass die Kontaktflächen eine z .B. reibungserhöhende Prägung aufweisen. Durch eine derartige Prägung wird der mechanische Widerstand und somit der Sicherungseffekt weiter verstärkt.Alternatively, it can also be provided that the contact surfaces do not increase or increase in a direction opposite to the actuating direction increasingly. In a further development can also be provided that the contact surfaces a z .B. have friction-increasing embossing. Such an embossing further strengthens the mechanical resistance and thus the securing effect.
Ferner kann wenigstens ein Steg wenigstens eine Bohrung haben, die im wesentlichen koaxial zu der Betätigungsrichtung orientiert ist und deren Gestalt dem Steg eine Nachgiebigkeit relativ zu einer Klemmschraube verleiht, wobei das Maß der Nachgiebigkeit durch die Gestalt der Bohrung bestimmt ist. Dabei kann die Bohrung des Stegs unterschiedlich groß dimensioniert sein, sowohl bezüglich ihrer Tiefe als auch ihres Durchmessers. Außerdem kann die Bohrung unterschiedliche Querschnitte aufweisen, z. B. einen kreisförmigen oder ellipsenförmigen Querschnitt.Further, at least one web may have at least one bore substantially coaxial with the direction of actuation and the shape of which gives the web a compliance relative to a clamping screw, the degree of compliance being determined by the shape of the bore. In this case, the bore of the web can be dimensioned differently large, both in terms of their depth and their diameter. In addition, the bore may have different cross sections, z. B. a circular or elliptical cross-section.
Weiterhin kann vorgesehen sein, dass die Ausnehmung entgegen der Einsetzrichtung geöffnet ausgebildet ist, um ein Einsetzen des Kontakteinsatzes mit vormontierter Klemmvorrichtung in den Isolierkörper zu ermöglichen. Dabei weist die Ausnehmung eine Öffnung in Richtung entgegengesetzt der Einsetzrichtung auf, die groß genug ist, um eine an einem Kontakteinsatz vormontierte Klemmschraube einzuführen. Dieses vereinfacht insbesondere die Montage der Steckverbinder, da der Kontakteinsatz und die vormontierte Klemmvorrichtung als eine Baugruppe in den Isolierkörper eingebracht werden können.Furthermore, it can be provided that the recess is formed open against the insertion direction to allow insertion of the contact insert with preassembled clamping device in the insulating body. In this case, the recess has an opening in the direction opposite to the insertion direction, which is large enough to introduce a pre-assembled on a contact insert clamping screw. This simplifies in particular the assembly of the connector, since the contact insert and the preassembled clamping device can be introduced as an assembly in the insulating body.
Bei einer Weiterbildung der Erfindung kann vorgesehen sein, dass der Kontakteinsatz im Bereich der Einführöffnung eine Kontaktinnenfläche für den Leiter aufweist, gegen die der Leiter durch die Klemmvorrichtung gedrückt wird und die zur Erhöhung der Anzahl der Kontaktstellen des Leiters mit dem Kontakteinsatz eine makroskopische Oberflächenstruktur besitzt. Dabei kann die makroskopische Oberflächenstruktur in einer die Mittellängsachse enthaltenden Schnittansicht ein sägezahnartiges Profil aufweisen, dessen Spitzen von der Einführöffnung wegweisen. Das sägezahnartige Profil erzeugt einen gerichteten mechanischen Widerstand, ähnlich einem Widerhaken, der die Bewegung des Leiters in eine Richtung (Einführen) nicht maßgeblich beeinflusst, während er eine Bewegung in die entgegengesetzte Richtung (Herausziehen) erschwert. Dieses wird dadurch erreicht, dass das Profil mit seinen der Bewegung entgegengesetzten Spitzen die notwendige Auszugkraft des Leiters erhöht.In a development of the invention it can be provided that the contact insert in the region of the insertion opening has a contact inner surface for the conductor, against which the conductor is pressed by the clamping device and which has a macroscopic surface structure to increase the number of contact points of the conductor with the contact insert. The macroscopic surface structure in one of the central longitudinal axis containing sectional view have a sawtooth-like profile, the tips of which point away from the insertion opening. The sawtooth profile produces a directional mechanical resistance, similar to a barb, that does not significantly affect the movement of the conductor in one direction (insertion) while making it difficult to move in the opposite direction (withdrawal). This is achieved by the fact that the profile with its opposite movement of the tips increases the necessary extraction force of the conductor.
Ferner kann der Kontakteinsatz einen Eingriffsbereich aufweisen, in dem wenigstens eine formschlüssige Verbindungsstelle zur Bildung des zylinderförmigen Kontakteinsatzes angeordnet ist. Auf diese Weise kann aus einem im wesentlichen ebenen Grundmaterial ein zylinderförmiger Kontakteinsatz hergestellt werden, indem an zwei zu verbindendenden Außenkanten des ebenen Grundmaterials eine Eingriffsformation, beispielsweise eine Ausbuchtung, und eine korrespondierende Aufnahmeformation, beispielsweise eine Ausnehmung, zur Herstellung einer formschlüssigen Verbindung vorgesehen sind. Alternativ ist es jedoch auch denkbar die entsprechenden Außenkanten beispielsweise stoffschlüssig durch Schweißen oder dergl. zu verbinden.Furthermore, the contact insert may have an engagement region in which at least one positive connection point for forming the cylindrical contact insert is arranged. In this way, a cylindrical contact insert can be produced from a substantially planar base material by providing an engagement formation, for example a bulge, and a corresponding receiving formation, for example a recess, for producing a positive connection at two outer edges of the planar base material to be joined. Alternatively, however, it is also conceivable to connect the corresponding outer edges, for example by material bonding, by welding or the like.
Bei einer Weiterbildung der Erfindung kann vorgesehen sein, dass der Kontakteinsatz wenigstens eine Stützfläche zur Auflage auf wenigstens einer korrespondierenden Auflagefläche im Isolierkörper aufweist. Die Stützfläche ermöglicht einerseits eine positionsgenaue Einbringung des Kontakteinsatzes in den Isolierkörper und begrenzt andererseits die Einführtiefe des Kontakteinsatzes in den Isolierkörper.In a development of the invention it can be provided that the contact insert has at least one support surface for resting on at least one corresponding bearing surface in the insulating body. The support surface allows on the one hand a positionally accurate introduction of the contact insert in the insulating body and limits the other hand, the insertion depth of the contact insert in the insulating body.
Ferner kann vorgesehen sein, dass der Kontakteinsatz einen Leiterschutz aufweist, der integral mit dem Kontakteinsatz verbunden ist. In einer Weiterbildung der Erfindung kann zudem vorgesehen sein, dass der Leiterschutz im Bereich der Einführöffnung von dem Kontakteinsatz vorragt und in einem Biegebereich mit einer solchen Biegung ausgebildet ist, dass er sich in die Einführöffnung hinein erstreckt. Dabei kann der Leiterschutz eine Prägung in seinem Biegebereich aufweisen, die eine definierte Federung des Leiterschutzes ermöglicht. Ein derartiger Leiterschutz ist insbesondere dann vorteilhaft, wenn die Klemmvorrichtung eine Klemmschraube aufweist, die ohne Leiterschutz in direktem Kontakt mit dem eingefügten Leiter stünde und diesen ggf. beschädigen könnte. Bei den bisher bekannten Steckverbindern ist ein solcher Leiterschutz stets als separates Teil ausgeführt, das zusätzlich in den Kontakteinsatz eingebracht und gesichert werden muss. Die integrale Ausbildung des Leiterschutzes macht eine zusätzliche Sicherung überflüssig ohne die Funktionalität des Leiterschutzes dadurch einzuschränken.Furthermore, it can be provided that the contact insert has a conductor protection, which is integrally connected to the contact insert. In one development of the invention, it can also be provided that the conductor protection protrudes from the contact insert in the region of the insertion opening and is formed in a bending region with such a bend that it extends into the insertion opening. In this case, the conductor protection have an embossing in its bending region, which allows a defined suspension of the conductor protection. Such a conductor protection is particularly advantageous if the clamping device has a clamping screw, which would be in direct contact with the inserted conductor without conductor protection and possibly damage it. In the previously known connectors, such a conductor protection is always designed as a separate part, which must be additionally introduced and secured in the contact insert. The integral design of the conductor protection makes an additional fuse superfluous without restricting the functionality of the conductor protection.
Alternativ zu einer Klemmschraube kann die Klemmvorrichtung ein schraubenloses Klemmelement in Form einer Klemmfeder umfassen, die durch eine an dem Kontakteinsatz angeordnete Öffnung mittels eines Betätigungswerkzeugs betätigbar ist. Dabei kann vorgesehen sein, dass die Klemmfeder in einer die Mittellängsachse enthaltenden Schnittansicht einen im wesentlichen V-förmigen Querschnitt mit zwei Schenkeln aufweist, die infolge elastischer Verformung relativ zueinander bewegbar sind. Ferner kann die Klemmfeder einen Klemmschenkel aufweisen, um den Leiter gegen den Kontakteinsatz zu klemmen, sowie einen Stützschenkel zur Abstützung der Klemmfeder an dem Kontakteinsatz. Die Klemmfeder kann als separates Teil in den Kontakteinsatz eingesetzt werden oder integral mit dem Kontakteinsatz verbunden ausgebildet sein. In letzterem Fall stützt der Stützschenkel sich nicht nur an dem Kontakteinsatz ab, sondern bildet einen Teil des Kontakteinsatzes. Die Klemmfeder kann ferner an ihrem Klemmschenkel eine Aufnahme für das Betätigungswerkzeug aufweisen. Diese Aufnahme kann beispielsweise durch eine Ausnehmung oder/und einen gebogenen Bereich des Klemmschenkels ausgebildet sein. Mit ihrer Hilfe ist es auf einfache Weise möglich, ein Betätigungswerkzeug, das durch die an dem Isolierkörper angebrachte Ausnehmung und die an dem Kontakteinsatz angeordnete Öffnung führbar ist, aufzunehmen und damit den Klemmschenkel in Richtung zu dem Stützschenkel der Klemmfeder zu bewegen. Um den Leiter mit der Klemmfeder zu befestigen, wird diese zuerst mit Hilfe des Betätigungswerkzeugs vorgespannt, indem der Klemmschenkel in Richtung des Stützschenkels bewegt wird. Nachfolgend wird der Leiter soweit in die Einführöffnung eingesetzt, dass der Klemmschenkel - sobald er nicht mehr mit dem Betätigungswerkzeug unter Vorspannung gehalten wird - den Leiter gegen die Kontaktfläche im Bereich der Einführöffnung drückt und auf diese Weise befestigt. Außerdem kann eine Weiterbildung der Erfindung vorsehen, dass die Öffnung an dem Kontakteinsatz in ihrer Form an die Anordnung der Klemmfeder in dem Kontakteinsatz angepasst ist, so dass sie wenigstens einen Anschlag zur Abstützung des Betätigungswerkzeugs bereitstellt. Dadurch wird insbesondere die Handhabung des Betätigungswerkzeugs erleichtert.As an alternative to a clamping screw, the clamping device may comprise a screwless clamping element in the form of a clamping spring which can be actuated by an opening arranged on the contact insert by means of an actuating tool. It can be provided that the clamping spring in a sectional view containing the central longitudinal axis has a substantially V-shaped cross section with two legs, which are movable relative to each other due to elastic deformation. Further, the clamping spring may have a clamping leg to clamp the conductor against the contact insert, and a support leg for supporting the clamping spring on the contact insert. The clamping spring can be used as a separate part in the contact insert or integrally formed connected to the contact insert. In the latter case, the support leg not only supports on the contact insert, but forms part of the contact insert. The clamping spring may further comprise at its clamping leg a receptacle for the actuating tool. This receptacle can be formed for example by a recess and / or a bent portion of the clamping leg. With their help, it is possible in a simple manner, an actuating tool, which is feasible by the attached to the insulating recess and the opening arranged on the contact insert, and thus to move the clamping leg in the direction of the support leg of the clamping spring. To secure the conductor with the clamping spring, this is first biased by means of the actuating tool by the clamping leg is moved in the direction of the support leg. Subsequently, the conductor is inserted into the insertion opening so far that the clamping leg - as soon as it is no longer held under tension with the actuating tool - presses the conductor against the contact surface in the region of the insertion opening and fastened in this way. In addition, a development of the invention provide that the opening on the contact insert is adapted in shape to the arrangement of the clamping spring in the contact insert, so that it provides at least one stop for supporting the actuating tool. As a result, in particular the handling of the actuating tool is facilitated.
Abschließend kann vorgesehen sein, dass der Kontakteinsatz ausgebildet ist, um aus einem ebenen Blech durch Stanzen und durch Biegen hergestellt zu sein. Dabei ist der Kontakteinsatz konstruktiv derart ausgelegt, dass er als ganzes aus einem ebenen Blech ausgestanzt und durch Biegen einzelner Partien zu dem zylinderförmigen Kontaktelement geformt werden kann. Dies ermöglicht eine kostengünstigere Produktion im Vergleich zu den gängigen spanenden Herstellungsverfahren, wie Drehen des Kontakteinsatzes, und senkt weiter die Produktionskosten.Finally, it can be provided that the contact insert is designed to be made of a flat sheet by punching and bending. In this case, the contact insert is structurally designed such that it can be punched out as a whole from a flat sheet metal and formed by bending individual parts to the cylindrical contact element. This allows a more cost-effective production compared to the common machining processes, such as turning the contact insert, and further reduces the production costs.

So kann der Einführwinkel beispielsweise mehr als 50° betragen, während der Austrittswinkel beispielsweise weniger als 40° beträgt. Der in der Einführöffnung eingeführte Leiter wird auf diese Weise zusätzlich zu der durch die Klemmschraube 16 bewirkten Haltekraft gegen ein unerwünschtes Herausziehen aus dem Kontakteinsatz 12 gesichert.For example, the insertion angle can be more than 50 °, while the exit angle is less than 40 °, for example.

An der Außenseite des Kontakteinsatzes 12 sind in seinem Verbindungsbereich 22 zwei Rastelemente 38 in Form von federnden Rasthaken ausgebildet. Diese werden einfach aus dem ebenen Grundmaterial mit Ausnahme eines Haltestegs 40 ausgestanzt und nach außen gebogen. Auf diese Weise entsteht eine dem zweiten Ende des Kontakteinsatzes 12 zugewandte Wirkfläche 42, die sich an einem an dem Isolierkörper 14 angebrachten Anschlag 44 in einer Richtung entgegen der Einsetzrichtung E sperrend abstützen kann. Der Kontakteinsatz 12 wird in der Einsetzrichtung E in den Isolierkörper 14 eingeschoben, bis die Wirkflächen 42 der beiden Rastelemente 38 gegen die Anschläge 44 verrasten und eine Auszugsbewegung durch ihre im Eingriff mit den Anschlägen 44 befindlichen Wirkflächen 42 sperren.
