Kontaktorgan mit Doppel-SchneidklemmanschlußContact element with double insulation displacement connection
Die Erfindung betrifft ein Kontaktorgan mit Doppel - Schneidklemmanschluß, der aus zwei zueinander parallelen und mit jeweils einem Schneidklemm-Kontaktschlitz versehenen Kontaktschenkeln und einem diese Kontaktschenkeln miteinander verbindenden Mittelteil besteht.The invention relates to a contact element with a double insulation displacement connection, which consists of two mutually parallel contact legs, each provided with an insulation displacement contact slot, and a central part connecting these contact legs to one another.
Kontaktorgane werden zum abisolierfreien elektrischen Anschluß isolierter elektrischer Leiter häufig mit Schneidklemmanschlüssen versehen, die aus zwei zueinander parallelen und mit jeweils einem Schneidklemm-Kontaktschlitz versehenen Kon- taktschenkeln und einem diese Kontaktschenkel miteinander verbindenden Mittelteil bestehen. Dabei bildet der Schneid- klemmanschluß meistens einen im Querschnitt U-förmigen Bereich, der an einem Kontaktbereich des Kontaktorganes , z. B. an einer Kontaktfeder für die Kontaktierung eines Steckkon- taktes, angesetzt oder mit diesem Kontaktbereich einteilig ausgebildet ist . Ein derartiges Kontaktorgan ist zum Beispiel aus dem DE-GM 89 09 562 bekannt.Contact elements for insulation-free electrical connection of insulated electrical conductors are often provided with insulation displacement connections, which consist of two mutually parallel contact legs, each provided with an insulation displacement contact slot, and a central part connecting these contact legs to one another. The insulation displacement connection mostly forms a cross-sectionally U-shaped area, which is connected to a contact area of the contact element, for. B. is attached to a contact spring for contacting a plug contact or is formed in one piece with this contact area. Such a contact member is known for example from DE-GM 89 09 562.
Der Erfindung liegt die Aufgabe zugrunde, ein Kontaktorgan der eingangs genannten Art mit einer kompakten, für die Kontaktierung von Messerkontakten geeigneten Bauform zu schaffen.The invention has for its object to provide a contact member of the type mentioned with a compact, suitable for contacting knife contacts design.
Diese Aufgabe wird bei einem Kontaktorgan der eingangs ge- nannten Art gemäß der Erfindung dadurch gelöst, daß das Mittelteil mit mindestens einer Ausnehmung versehen und diese Ausnehmung zumindest in einem Kontaktbereich für einen in das Mittelteil einsteckbaren Messerkontakt der Geometrie dieses Messerkontaktes angepaßt ist. Bei einem derartigen Kontaktorgan ist das die Kontaktschenkel miteinander verbindende Mittelteil mit mindestens einer Auε- nehmung für das Einstecken eines Messerkontaktes ausgebildet, so daß es außer seiner Funktion als Verbindungselement für die KontaktSchenkel gleichzeitig auch als Steckkontaktbereich für einen einsteckbaren Messerkontakt dient. Auf diese Weise läßt sich ein Kontaktorgan in äußerst kompakter Bauform mit Doppel-Sehneidklemmanschluß und Steckkontaktbereich realisieren. Das erfindungsgemäße Kontaktorgan kann daher in Bauhöhe und Baulänge mit sehr geringen Einbaumaßen hergestellt werden und ist besonders vorteilhaft geeignet für die Kontaktierung von zum Schneidklemmanschluß senkrecht stehenden Messerkontakten, d. h. von senkrecht zur Ebene des Mittelteiles einsteckbaren Messerkontakten. Beim Stecken von Messerkontakten in Ausnehmungen des Mittelteiles weiten sich diese Ausnehmungen in Querrichtung, d. h. quer zu den freien Längsseiten des Mittelteiles, auf und erzeugen hierdurch die Kontaktkraft. Die Ausnehmungen des Mittelteiles sind mit ihrer Öffnungsweite und in ihrer Länge zweckmäßigerweise derart ausgebildet und der Geometrie von Messerkontakten angepaßt, daß die erforderliche Kontaktkraft zur Verfügung steht.This object is achieved in a contact element of the type mentioned at the outset according to the invention in that the middle part is provided with at least one recess and this recess is adapted at least in a contact area for a knife contact which can be inserted into the middle part to the geometry of this knife contact. In such a contact element, the middle part connecting the contact legs is designed with at least one recess for inserting a knife contact, so that, in addition to its function as a connecting element for the contact legs, it also serves as a plug-in contact area for an insertable knife contact. In this way, a contact element can be realized in an extremely compact design with a double optical terminal connection and plug contact area. The contact element according to the invention can therefore be manufactured with very small installation dimensions and length and is particularly advantageously suitable for contacting knife contacts which are perpendicular to the insulation displacement connection, ie knife contacts which can be inserted perpendicular to the plane of the central part. When knife contacts are inserted into recesses in the middle part, these recesses widen in the transverse direction, ie transverse to the free long sides of the middle part, and thereby generate the contact force. The recesses of the middle part are expediently designed with their opening width and in their length and adapted to the geometry of the knife contacts in such a way that the required contact force is available.
Vorteilhafterweise ist bei einem erfindungsgemäßen Kontaktorgan die Ausnehmung schlitzförmig ausgebildet, wobei sie etwa parallel zu den freien Längsseiten des Mittelteiles, also quer zu den Kontaktschenkein, verläuft. Eine derartige Ausnehmung kann dann unmittelbar den Kontaktbereich für einen flachen Messerkontakt bilden.In the case of a contact element according to the invention, the recess is advantageously slit-shaped, running approximately parallel to the free longitudinal sides of the central part, that is to say transversely to the contact legs. Such a recess can then directly form the contact area for a flat knife contact.
Wenn bei einem erfindungsgemäßen Kontaktorgan das Mittelteil jedoch als Steck-Kontaktbereich für runde oder rechteckige Kontaktstifte dient, so ist es zweckmäßig, wenn die schlitzförmige Ausnehmung von einem runden oder rechteckigen der Geometrie eines Kontaktstiftes angepaßten Durchbruch als Kon- taktbereich für den Kontaktstift durchsetzt ist. Vorteilhafte weitere Ausgestaltungen des Gegenstandes des Anspruches l sind in den übrigen Unteransprüchen angegeben.If, however, the middle part of a contact element according to the invention serves as a plug-in contact area for round or rectangular contact pins, it is expedient if the slot-shaped recess is penetrated by a round or rectangular opening adapted to the geometry of a contact pin as a contact area for the contact pin. Advantageous further developments of the subject matter of claim 1 are specified in the remaining subclaims.
Die Erfindung wird im folgenden anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Es zeigen in perspektivischen DarstellungenThe invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. They show in perspective representations

FIG. 2 shows another contact element with a view of one side of the double insulation displacement connection.
Figur 3 eine weitere Ausführungsform eines Kontaktorganes und Figur 4 das Kontaktorgan nach Figur 3 mit Leitungs- und Messerkontakt-Anschluß.3 shows a further embodiment of a contact element and FIG. 4 the contact element according to FIG. 3 with a line and knife contact connection.
Das Kontaktorgan 1, la und lb ist von einem im Querschnitt U- förmigen, aus einem Blechteil in einem Stanz-Biegeverfahren hergestellten Teil mit einem Doppel-Schneidklemmanschluß 2 zum abisolierfreien elektrischen Anschluß eines isolierten elektrischen Leiters 28 gebildet. Der Doppel- Schneidklemmanschluß 2 besteht aus zwei zueinander parallelen KontaktSchenkeln 3, 4, die mit jeweils einem Schneidklemm- Kontaktschlitz 5, 6 versehen und hier an ihrer der offenen Einführseite der Schneidklemm-Kontaktschlitze gegenüberlie- genden Seite über ein einen Boden des Kontaktorganes bildendes Mittelteil 7 miteinander verbunden sind. Die Schneidklemm-Kontaktschlitze 5, 6 sind hier z. B. in besonderer, aus der deutschen Offenleg ngsschrift 41 08 133 bekannten Weise mit Schneidspitzen 8, Schneidkanten 9, Orientierungskanten 10, Verformungskanten 11 im Einführbereich und Klemmkanten 12 im Klemmbereich des Kontaktschlitzes ausgebildet und reichen bei dem Kontaktorgan 1 in Figur 1 z. B. über etwa zwei Drittel der Höhe der Kontaktschenkel 3 , 4. Das Mittelteil 7 des Kontaktorganes l ist hier mit zwei zueinander und zu den freien Längsseiten 13 , 14 parallelen schlitzförmigen Ausnehmungen 15, 16 ausgebildet, welche sich in Längsrichtung des Mittelteiles, also quer zu den Kontakt- Schenkeln 3, 4, über die gesamte Länge des Mittelteiles hinaus und über die Abbiegungen der Kontaktschenkel 3 , 4 sogar in diese hineinerstrecken. Etwa in der Mitte der Länge des Mittelteiles 7 sind die schlitzförmigen Ausnehmungen 15, 16 mit jeweils einem runden, diametral von den Ausnehmungen durchsetzten Durchbruch 17, 18 als Kontaktbereich für hier als runde Kontaktstifte ausgebildete Messerkontakte 19 versehen, wobei diese Durchbrüche dann der Geometrie der in das Mittelteil 7 einsteckbaren Messerkontakte angepaßt ist. Die Durchbrüche 17, 18 sind an der Steckseite, also an der Unter- seite des Mittelteiles 7, zur Erleichterung der Einführung der Messerkontakte mit Einführungen 20 in Form von Einlaufra- dien oder Einlaufschrägen ausgebildet. Beim Stecken der Messerkontakte 19 in die Durchbrüche 17, 18 weiten sich diese und die Ausnehmungen 15, 16 in Querrichtung elastisch auf und erzeugen hierdurch die Kontaktkraft. Damit diese in erforderlichem Maße zur Verfügung steht, ist die Öffnungsweite der Durchbrüche 17, 18 sowie die Länge der schlitzförmigen Ausnehmungen 15, 16 entsprechend an die Dicke der Messerkontakte angepaßt .The contact element 1, la and lb is formed by a part with a U-shaped cross section, made from a sheet metal part in a stamping and bending process, with a double insulation displacement connection 2 for stripping-free electrical connection of an insulated electrical conductor 28. The double insulation displacement connection 2 consists of two mutually parallel contact legs 3, 4, each provided with an insulation displacement contact slot 5, 6 and here on its side opposite the open insertion side of the insulation displacement contact slots via a central part 7 forming a base of the contact element are interconnected. The insulation displacement contact slots 5, 6 are here, for. B. in a special, from German published publication 41 08 133 known manner with cutting tips 8, cutting edges 9, orientation edges 10, deformation edges 11 in the insertion area and clamping edges 12 in the clamping area of the contact slot and are sufficient for the contact element 1 in FIG. B. about two-thirds of the height of the contact legs 3, 4th The middle part 7 of the contact element 1 is formed here with two slot-shaped recesses 15, 16 which are parallel to one another and to the free longitudinal sides 13, 14 and which extend in the longitudinal direction of the middle part, that is to say transversely to the contact legs 3, 4, over the entire length of the Middle part and even extend into the bends of the contact legs 3, 4. Approximately in the middle of the length of the central part 7, the slot-shaped recesses 15, 16 are each provided with a round opening 17, 18, diametrically penetrated by the recesses, as a contact area for knife contacts 19 designed here as round contact pins, these openings then corresponding to the geometry of FIG the middle part 7 plug-in knife contacts is adapted. The openings 17, 18 are formed on the plug-in side, that is to say on the underside of the central part 7, in order to facilitate the introduction of the knife contacts with inlets 20 in the form of inlet radii or inlet bevels. When the knife contacts 19 are inserted into the openings 17, 18, these and the recesses 15, 16 expand elastically in the transverse direction and thereby generate the contact force. So that this is available to the extent required, the opening width of the openings 17, 18 and the length of the slot-shaped recesses 15, 16 are adapted accordingly to the thickness of the knife contacts.
Für den Fall, daß das Kontaktorgan l fest in einem Gehäuse fixiert werden soll, ist es zweckmäßig, wenn die Kontaktschenkel 3 , 4 an zwei einander gegenüberliegenden Seitenkanten 21, 22 Vorsprünge 23 aufweisen, die in vorteilhafterweise eine tannenbaumartige Geometrie besitzen, welche bei dem dargestellten Ausführungsbeispiel umgekehrt ist, um die in Figur 1 von unten auf das Mittelteil 7 einwirkenden Steckkräfte aufzunehmen. Die Vorsprünge 23 sind im stabilen Bereich der Kontaktschenkel 3 , 4 außerhalb der Schneidklemm- Kontaktschlitze 5, 6 sowie der Durchbrüche 17, 18 vorgesehen, um die Auf eitung der Schneidklemm-Kontaktschlitze 5, 6 bzw. der KontaktÖf nungen bildenden Durchbrüche 17, 18 nicht zu behindern .In the event that the contact member l is to be fixed firmly in a housing, it is expedient if the contact legs 3, 4 have projections 23 on two opposite side edges 21, 22, which advantageously have a fir tree-like geometry, which in the case of the illustrated one Embodiment is reversed to absorb the insertion forces acting on the central part 7 from below in FIG. The projections 23 are provided in the stable area of the contact legs 3, 4 outside the insulation displacement contact slots 5, 6 and the openings 17, 18, in order not to impede the opening of the insulation displacement contact slots 5, 6 or the openings 17, 18 forming contact openings.
Im Falle einer schwimmenden Fixierung des Kontaktorganes la in einem Gehäuse bietet sich die Möglichkeit, dies über federnde Schnapphaken 24 des Gehäuses zu realisieren, die das Kontaktorgan la entweder an dem den Boden bildenden Mittelteil 7 oder an den beiden Kontaktschenkeln 3 , 4 umgreifen und festhalten (Figur 2) .In the case of a floating fixation of the contact element la in a housing, there is the possibility of realizing this via resilient snap hooks 24 of the housing, which grip the contact element la either on the central part 7 forming the bottom or on the two contact legs 3, 4 and hold it in place ( Figure 2).
Ferner ist es zur Fixierung eines Kontaktorganes in einem Gehäuse möglich, wie bei dem Kontaktorgan lb in den Figuren 3 und 4, z. B. an den hinteren Seitenkanten 26, 27 der Kontakt- schenke! 3, 4 seitlich abgebogene Befestigungslappen 25 vorzusehen, welche in z. B. federnde Rastelemente im Inneren des Gehäuses einschnappen. Diese Befestigungεlappen sind bei dem Kontaktorgan lb unmittelbar unterhalb des Schneidklemmbereiches der Kontaktschenkel 3, 4 angeordnet. Im übrigen ent- spricht das Kontaktorgan lb nach den Figuren 3 und 4 in seinem grundsätzlichem Aufbau und der Funktion und Ausbildung des Mittelteiles 7 dem Kontaktorgan 1 in Figur 1, wobei sich das Kontaktorgan lb lediglich dadurch von dem Kontaktorgan l unterscheidet, daß es anders als dieses lediglich eine Aus- nehmung 15 für einen als runder Kontaktstift ausgebildeten Messerkontakt aufweist.Furthermore, it is possible to fix a contact member in a housing, as in the contact member lb in Figures 3 and 4, for. B. on the rear side edges 26, 27 of the contact legs! 3, 4 to provide laterally bent mounting tabs 25, which in z. B. snap resilient locking elements inside the housing. These fastening tabs are arranged in the contact element 1b directly below the insulation displacement area of the contact legs 3, 4. Otherwise, the contact element 1b according to FIGS. 3 and 4 corresponds in its basic structure and the function and design of the central part 7 to the contact element 1 in FIG. 1, the contact element 1b only differing from the contact element 1 in that it differs from this only has a recess 15 for a knife contact designed as a round contact pin.
Bei den dargestellten Ausführungsformen ist das Kontaktorgan in seinem Mittelteil 7 mit Durchbrüchen für stiftförmige Mes- serkontakte ausgebildet. Es ist jedoch auch möglich, bei entsprechender Anpassung der Geometrie der Durchbrüche bzw. der schlitzförmigen Ausnehmungen selbst flache Messerkontakte in das Mittelteil einzustecken. Ferner ist es in Abwandlung der dargestellten Ausführungsformen auch möglich, die Verbindung der Kontaktschenkel 3, 4 über das Mittelteil 7 seitlich, d. h. zum Beispiel an den Seitenkanten 21 oder 22 der Kontaktschenkel 3, 4 vorzusehen. In the illustrated embodiments, the contact member is formed in its central part 7 with openings for pin-shaped knife contacts. However, it is also possible, with a corresponding adaptation of the geometry of the openings or of the slot-shaped recesses, to insert even flat knife contacts into the middle part. Furthermore, in a modification of the illustrated embodiments, it is also possible to provide the connection of the contact legs 3, 4 laterally via the central part 7, that is to say, for example, on the side edges 21 or 22 of the contact legs 3, 4.
