Definitions
- the invention relates to a contact spring bushing according to the preamble of patent claim 1.
- a plug-in contact spring punched out of flat material is known from DE-OS 36 36 711.
- this plug contact spring consists of a connecting part for electrical jumper wires and a plug part for receiving a pin-like mating connector.
- the plug part is designed such that the bending arms, each carrying a contact spring, are bent over the high edge when plugged in.
- the connecting part in this plug contact spring is designed so that the electrical jumper wires must be pretreated for contacting, at least the insulation having to be removed. It is not specified in detail how the jumper wires are attached to the connector.
- a method for producing a clamping device for connecting electrical lines by cutting the insulation is known from DE-AS 15 90 699. These are specially shaped insulation displacement clamps which are stamped in such a way that a slot is formed into which a wire to be contacted is clamped. This creates a high pressure, so that a perfect electrical connection is guaranteed.
- the insulation displacement connection is described, which has the advantage that the insulation of wires does not have to be removed beforehand. None is said about the way in which a plug connection can be implemented.
- the object of the invention is to present a contact spring book which can be produced from one part and does not require any pretreatment of the connecting wires to be contacted.
- the contact spring bushing should be such that it can be manufactured without assembly work and can be inserted into an associated insulating housing, with no additional fastening parts being required. No additional tools should be required for contacting the connecting wires.
- FIG. 1 shows a socket body 1 with a shaft 5, which is automatically produced from a stamped part by several bending steps, as shown in FIG. 2.
- the bending steps can directly follow the punching steps, so that the contact spring bushing is produced by an automatically controlled punching and bending machine.
- the metal parts 2 used to produce the contact spring bushings are arranged in a stamped strip in a known manner, this arrangement also being maintained until the bending operations have ended. Only when the finished socket body 1 is inserted into the respective insulating housing 8 are the contact spring sockets isolated.
- the actual contact springs 4 are spoon-shaped and are enclosed by compression springs 3, which increases the contact pressure.
- These compression springs 3 are connected by strips 10 to the socket body 1, as is clearly shown in FIG. 2. As part of the bending processes necessary for the manufacture of the contact spring bushing, these strips 10 are pressed together in a meandering fashion 11, so that the compression springs 3 come to rest on the contact springs 4. In a subsequent bending process, the compression springs 3 are pressed against the contact springs 4 pressed.
- the shaft 5 of the socket body 1 has insulation displacement clamps 6 which are bent vertically out of the plane by a bending process.
- the connecting wire to be contacted is inserted into these insulation displacement terminals without removing the insulation. However, this only happens when the contact spring bushing has been inserted into the insulating housing 8.
- hooks 7 are provided, which are bent obliquely out of the plane and are used for strain relief of the connecting wire.
- FIG. 3 does not contain any reference numerals because these are indicated in the correspondingly enlarged FIG. 2.
- the bending processes take place one after the other, so that after they have been completed a strip is formed, as shown in FIG. 4.
- the reference symbols given in FIG. 4 correspond to the parts as can be seen more clearly from FIG. 1.
- the strip shown in FIG. 4 thus already contains the finished socket body 1. These socket bodies remain in the strip until they are mechanically inserted into the housing 8.
- FIG. 5 A perspective sectional drawing of a housing 8 for receiving the socket body 1 is shown in FIG. 5.
- the socket body 1 is inserted into the housing 8 from below, barbs 17 located on the socket body 1 being hooked into notches 18.
- the shaft 5 of the socket body 1 is then located in the upper part of the housing 8.
- detents 12 are attached, which are intended for the contacting tool 9.
- This contacting tool 9 is produced together with the housing 8 in one operation and in one piece. It is connected to the housing 8 by webs 14 designed as predetermined breaking points.
- the contacting tool 9 has slots 16, which are arranged such that they are located above the insulation displacement contacts 6.
- the contacting of a connecting wire can only take place when the socket body 1 has been inserted into the housing 8.
- the connecting wire is simply inserted into the shaft 5 of the socket body, and the contacting tool 9 is pressed into the housing 8.
- the contacting tool 9 has 2 roof slopes 15, of which only one can be seen in the sectional drawing, so that the connecting wire can be gripped and fixed.
- the latching lugs 13 latch in the latches 12 of the housing on both sides, so that the connecting wire is pressed into the insulation displacement terminals 6.
- the connecting wire is also pressed against the hook 7, so that there is strain relief.
- the manufacturing processes for producing the contact spring bushing can be carried out both for the socket body 1 and for the housing 8 by automatically controlled machines. Automatically operating machines are also provided for inserting the socket body 1 into the housing 8 and for contacting the connecting wires.

Abstract
Description
Die Erfindung betrifft eine Kontaktfederbuchse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a contact spring bushing according to the preamble of
Eine aus Flachmaterial gestanzte Steckkontaktfeder ist aus der DE-OS 36 36 711 bekannt. Wie aus den Zeichnungen und der zugehörigen Beschreibung hervorgeht, besteht diese Steckkontaktfeder aus einem Anschlußteil für elektrische Schaltdrähte und einem Steckerteil zum Aufnehmen eines stiftartigen Gegensteckers. Um eine ausreichend große Kontaktkraft zu erreichen, ist das Steckerteil so ausgebildet, daß die je eine Kontaktfeder tragenden Biegearme beim Stecken über die hohe Kante gebogen werden. Das Anschlußteil bei dieser Steckkontaktfeder ist so ausgebildet, daß die elektrischen Schaltdrähte für die Ankontaktierung vorbehandelt werden müssen, wobei mindestens die Isolation entfernt werden muß. Es ist nicht im einzelnen angegeben, auf welche Weise die Schaltdrähte mit dem Anschlußteil befestigt werden.A plug-in contact spring punched out of flat material is known from DE-OS 36 36 711. As is apparent from the drawings and the associated description, this plug contact spring consists of a connecting part for electrical jumper wires and a plug part for receiving a pin-like mating connector. In order to achieve a sufficiently large contact force, the plug part is designed such that the bending arms, each carrying a contact spring, are bent over the high edge when plugged in. The connecting part in this plug contact spring is designed so that the electrical jumper wires must be pretreated for contacting, at least the insulation having to be removed. It is not specified in detail how the jumper wires are attached to the connector.
Aus der DE-PS 8 91 827 ist eine elektrische Steckverbindung zur Aufnahme insbesondere flacher Steckerstifte bekannt. Hierbei ist eine zusätzliche U-förmig gebogene zusammenfedernde Stahlfeder eingesetzt, um einen höheren Kontaktdruck zu erreichen. Zur Befestigung eines Anschlußdrahtes ist eine Klemmschraube vorgesehen. Diese Steckverbindung besteht aus mehreren verschiedenen Teilen welche einzel hergestellt werden und dann mit Hilfe besonderer Vorrichtungen montiert werden müssen.From DE-PS 8 91 827 an electrical connector for receiving in particular flat connector pins is known. Here, an additional U-shaped spring steel spring is used to achieve a higher contact pressure. To attach a Connecting wire, a clamping screw is provided. This connector consists of several different parts which are manufactured individually and then have to be assembled using special devices.
Ein Verfahren zur Herstellung einer Klemmvorrichtung für den Anschluß elektrischer Leitungen unter Durchschneiden der Isolation ist aus der DE-AS 15 90 699 bekannt. Dabei handelt es sich um besonders geformte Schneidklemmen, welche so gestanzt sind, daß ein Schlitz entsteht, in den ein anzukontaktierender Draht eingeklemmt wird. Dabei entsteht ein hoher Druck, so daß eine einwandfreie elektrische Verbindung gewährleistet ist. In dieser Schrift ist lediglich die Schneidklemmverbindung beschrieben, welche den Vorteil hat, daß die Isolation von Drähten nicht vorher entfernt werden muß. Es ist nichts darüber ausgesagt, auf welche Weise eine Steckverbindung realisiert werden kann.A method for producing a clamping device for connecting electrical lines by cutting the insulation is known from DE-AS 15 90 699. These are specially shaped insulation displacement clamps which are stamped in such a way that a slot is formed into which a wire to be contacted is clamped. This creates a high pressure, so that a perfect electrical connection is guaranteed. In this document, only the insulation displacement connection is described, which has the advantage that the insulation of wires does not have to be removed beforehand. Nothing is said about the way in which a plug connection can be implemented.
Die Aufgabe der Erfindung besteht darin, eine Kontaktfederbuches vorzustellen, welche aus einem Teil herstellbar ist und keine Vorbehandlung der anzukontaktierenden Anschlußadern verlangt. Die Kontaktfederbuchse soll so beschaffen sein, daß sie ohne Montagearbeiten herstellbar ist und in ein zugehöriges isolierendes Gehäuse eingeschoben werden kann, wobei keine zusätzlichen Befestigungsteile erforderlich sind. Für das Ankontaktieren von Anschlußdrähten sollen keine zusätzlichen Werkzeuge erforderlich sein.The object of the invention is to present a contact spring book which can be produced from one part and does not require any pretreatment of the connecting wires to be contacted. The contact spring bushing should be such that it can be manufactured without assembly work and can be inserted into an associated insulating housing, with no additional fastening parts being required. No additional tools should be required for contacting the connecting wires.
Zur Lösung dieser Aufgabe ist eine Merkmalskombination vorgesehen, wie sie im Patentanspruch 1 angegen ist.To achieve this object, a combination of features is provided as set out in
Damit wird in vorteilhafter Weise erreicht, daß eine preisgünstige Großserien-Herstellung ermöglicht wird, und daß ein einfaches Ankontaktieren von nicht vorbehandelten Anschlußadern sowohl manuell als auch automatisch geschehen kann. Durch das Einbringen der Kontaktfederbuchse in ein isolierenden Gehäuse wird vermieden, daß sich damit bestückte stromführende Anschlußdrähte berühren können.In this way, it is advantageously achieved that inexpensive large-scale production is made possible, and that simple connection of non-pretreated connecting wires can be done both manually and automatically. By inserting the contact spring bushing into an insulating housing, it is avoided that current-carrying connecting wires can touch it.
Die in den Unteransprüchen angegebenen Weiterbildungen der Erfindung geben an, auf welche Weise sich die Eigenschaften der Kontaktfederbuchse bei der Herstellung und bei der Anwendung verbessern lassen.The developments of the invention specified in the subclaims indicate the manner in which the properties of the contact spring bushing can be improved during manufacture and during use.

Die Fig. 1 zeigt einen Buchsekörper 1 mit einem Schaft 5, welcher durch mehrere Biegeschritte automatisch aus einem Stanzteil hergestellt wird, wie es in Fig. 2 dargestellt ist. Die Biegeschritte können sich dabei unmittelbar an die Stanzschritte anschließen, so daß die Kontaktfederbuchse von einer automatisch gesteuerten Stanz- und Biegemaschine hergestellt wird. Die zur Herstellung der Kontaktfederbuchsen dienenden Metallteile 2 sind in bekannter Weise in einem Stanzstreifen angeordnet, wobei diese Anordnung auch bis zur Beendigung der Biegevorgänge beibehalten wird. Erst bei der Einführung der fertigen Buchsenkörper 1 in das jeweilige isolierende Gehäuse 8 werden die Kontaktfederbuchsen vereinzelt.FIG. 1 shows a
Die eigentlichen Kontaktfedern 4 sind löffelförmig ausgebildet und werden von Druckfedern 3 umschlossen, womit der Kontaktdruck erhöht wird. Diese Druckfedern 3 sind durch Bänder 10 mit dem Buchsenkörper 1 verbunden, wie dies in Fig. 2 deutlich dargestellt ist. Im Rahmen der für die Herstellung der Kontaktfederbuchse notwendigen Biegevorgänge werden diese Bänder 10 mäanderförmig 11 zusammengedrückt, so daß die Druckfedern 3 über die Kontaktfedern 4 zu liegen kommen. In einem anschließenden Biegevorgang werden die Druckfedern 3 gegen die Kontaktfedern 4 gedrückt.The
Der Schaft 5 des Buchsenkörpers 1 weist Schneidklemmen 6 auf, die durch einen Biegevorgang senkrecht aus der Ebene heraus gebogen werden. In diese Schneidklemmen wird die anzukontaktierende Anschlußader ohne Entfernen der Isolation eingelegt. Dies geschieht jedoch erst dann, wenn die Kontaktfederbuchse in das isolierende Gehäuse 8 eingeschoben worden ist. Außerdem sind Haken 7 vorgesehen, welche schräg aus der Ebene heraus gebogen werden und zur Zugentlasung der Anschlußader dienen.The
Bei der Herstellung der Kontaktfederbuchse werden zunächst alle Stanzschritte nacheinander durchgeführt, so daß ein Stanzstreifen entsteht wie er in Fig. 3 abgebildet ist. Die Fig. 3 enthält keine Bezugszeichen, weil diese in der entsprechend vergrößerten Fig. 2 angegeben sind. In Anschluß an die Stanzschritte finden die Biegevorgänge nacheinander statt, so daß nach deren Abschluß ein Streifen entsteht, wie er in Fig. 4 dargestellt ist. Die in Fig. 4 angegebenen Bezugszeichen entsprechen den Teilen, wie sie aus der Fig. 1 deutlicher zu erkennen sind. Der in Fig. 4 dargestellte Streifen enthält also bereits die fertigen Buchsenkörper 1. Diese Buchsenkörper bleiben solange in dem besagten Streifen, bis sie maschinell in die Gehäuse 8 eingeführt werden.In the manufacture of the contact spring bushing, all the stamping steps are first carried out in succession, so that a stamped strip is produced as shown in FIG. 3. FIG. 3 does not contain any reference numerals because these are indicated in the correspondingly enlarged FIG. 2. Following the stamping steps, the bending processes take place one after the other, so that after they have been completed a strip is formed, as shown in FIG. 4. The reference symbols given in FIG. 4 correspond to the parts as can be seen more clearly from FIG. 1. The strip shown in FIG. 4 thus already contains the finished
Eine perspektivische-Schnittzeichnung eines Gehäuses 8 zur Aufnahme des Buchsenkörpers 1 ist in der Fig. 5 dargestellt. Der Buchsenkörper 1 wird von unten in das Gehäuse 8 eingeschoben, wobei sich am Buchsenkörper 1 befindliche Widerhaken 17 in Kerben 18 verhaken. Der Schaft 5 des Buchsenkörpers 1 befindet sich dann im oberen Teil des Gehäuses 8. In diesem oberen Teil sind Rastungen 12 angebracht, welche für das Ankontaktierwerkzeug 9 bestimmt sind. Dieses Ankontaktierwerkzeug 9 wird zusammen mit dem Gehäuse 8 in einem Arbeitsgang und in einem Stück hergestellt. Es ist mit als Sollbruchstellen ausgebildeten Stegen 14 mit dem Gehäuse 8 verbunden. Das Ankontaktierwerkzeug 9 weist Schlitze 16 auf, welche so angeordnet sind, daß sie sich oberhalb der Schneidklemmen 6 befinden.A perspective sectional drawing of a
Die Ankontaktierung einer Anschlußader kann erst erfolgen, wenn der Buchsenkörper 1 in das Gehäuse 8 eingeschoben worden ist. Zu diesem Zweck wird die Anschlußader lediglich in den Schaft 5 des Buchsenkörpers eingeschoben, und das Ankontaktierwerkzeug 9 wird in das Gehäuse 8 hineingedrückt. Das Ankontaktierwerkzeug 9 weist 2 Dachschrägen 15 auf, wovon in der Schnittzeichnung nur eine zu sehen ist, damit die Anschlußader umfaßt und fixiert werden kann. Beim Eindrücken des Ankontaktierwerkzeuges 9 verrasten sich die Rastnasen 13 auf beiden Seiten in den Rastungen 12 des Gehäuses, so daß das Einpressen der Anschlußader in die Schneidklemmen 6 erfolgt. Dabei wird die Anschlußader außerdem gegen die Haken 7 gedrückt, so daß eine Zugentlastung gegeben ist. Somit wird also beim Eindrücken des Ankontaktierwerkzeuges 9 in einem Arbeitsgang sowohl eine elektrische als auch eine mechanische Verbindung zwischen der Anschlußader und der Kontaktfederbuchse hergestellt.The contacting of a connecting wire can only take place when the
Da bei den meisten elektrischen Geräten, insbesondere bei Fernmelde-Endgeräten Adernpaare vorkommen, werden die Gehäuse vorwiegend paarweise in einem Stück hergestellt, wie dies in Fig. 6 dargestellt ist. Somit können Kabeladern paarweise in einem Arbeitsgang in ein derartiges mit Buchsenkörpern bestücktes Gehäuse 8, welches aus zwei Kammern besteht, eingebracht werden. Es ist jedoch ohne weiteres möglich, die Gehäuse 8 zu vereinzeln, so daß einzelne Anschlußadern ebenfalls ankontaktiert werden können.Since most electrical devices, in particular telecommunication terminals, have wire pairs, the housings are predominantly made in one piece, as shown in FIG. 6. Thus, cable cores can be introduced in pairs in one operation into a
Die Herstellvorgänge, zum Produzieren der Kontaktfederbuchse können sowohl für den Buchsenkörper 1 als auch für das Gehäuse 8 von automatisch taktweise gesteuerten Maschinen durchgeführt werden. Auch für das Einbringen der Buchsenkörper 1 in die Gehäuse 8 sowie für das Ankontaktieren der Anschlußadern sind selbsttätig arbeitende Maschinen vorgesehen.The manufacturing processes for producing the contact spring bushing can be carried out both for the
