Die Erfindung betrifft einen Kontaktteilhalter für einen Federkontakt nach dem Oberbegriff des Anspruchs 1 und einen Federkontakt.The invention relates to a contact part holder for a spring contact according to the preamble of claim 1 and a spring contact.

Federkontakte können beispielsweise in einem Gehäuse angebracht sein. Ein Kontaktstift oder dergleichen kann in solch ein Gehäuse eingebracht und mit dem Federkontakt verbunden werden. Der Federkontakt ist an einen Stromkreis angeschlossen, wodurch beim Einbringen des Kontaktstiftes in das Gehäuse eine elektrisch leitende Verbindung hergestellt wird.Spring contacts may for example be mounted in a housing. A contact pin or the like may be inserted into such a housing and connected to the spring contact. The spring contact is connected to a circuit, whereby upon insertion of the contact pin in the housing an electrically conductive connection is made.

Aus dem Stand der Technik sind Federkontakte bekannt, bei denen der Kontaktteilhalter mehrteilig ausgebildet ist, wodurch ein größerer Platz benötigt wird. Federkontakte, die in Fahrzeugen eingesetzt werden, sollten jedoch kompakt ausgebildet sein. Ferner müssen die einzelnen Teile mehrteiliger Kontaktteilhalter zusammengebaut werden, was mit zusätzlichem Arbeitsaufwand verbunden ist.Spring contacts are known from the prior art, in which the contact part holder is designed in several parts, whereby a larger space is needed. However, spring contacts used in vehicles should be made compact. Furthermore, the individual parts of multi-part contact part holder must be assembled, which is associated with additional work.

Die Aufgabe der Erfindung besteht darin, einen Kontaktteilhalter für einen Federkontakt herzustellen, der kostengünstig ist, und einen Federkontakt bereitzustellen, der kompakt ausgebildet ist.The object of the invention is to produce a contact part holder for a spring contact, which is inexpensive, and to provide a spring contact, which is compact.

Die gattungsbildende DE 102 61 733 A1 beschreibt einen Federkontakt mit einem Kontaktstift und einer Feder. Der Kontaktstift und die Feder sind in einer Hülse aufgenommen. Insbesondere stützt sich die Feder an einem umgebogenen Steg der Hülse ab. Die Hülse wiederum ist in einem Hohlraum eines Gehäuses aufgenommen.The generic DE 102 61 733 A1 describes a spring contact with a contact pin and a spring. The contact pin and the spring are received in a sleeve. In particular, the spring is supported on a bent web of the sleeve. The sleeve in turn is received in a cavity of a housing.

Diese Aufgabe wird bei einem Kontaktteilhalter für einen Federkontakt eingangs genannter Art mit den Merkmalen des Anspruchs 1 gelöst. Durch die einstückige Ausbildung entfällt ein Zusammenbau, wodurch Kosten gespart werden.This object is achieved with a contact part holder for a spring contact of the type mentioned with the features of claim 1. The one-piece design eliminates assembly, which saves costs.

Es sind Fortsätze vorgesehen. Eine Feder, die Teil eines Federkontakts ist, stützt sich im zusammengebauten Zustand des Federkontakts an den Fortsätzen ab. Die Fortsätze können dabei abgewinkelt ausgebildet sein.There are extensions provided. A spring, which is part of a spring contact, is supported on the extensions in the assembled state of the spring contact. The extensions can be formed angled.

Es kann ein Befestigungsbereich vorgesehen sein, der den Kontaktteilhalter an einem Gehäuse befestigt.There may be provided a mounting area which secures the contact part holder to a housing.

Bevorzugt ist der Kontaktteilhalter ein Kontaktstück, das mit dem Stromkreis verbunden ist. Der Kontaktteilhalter ist dabei aus einem elektrisch leitenden Material wie Kupfer hergestellt.Preferably, the contact part holder is a contact piece which is connected to the circuit. The contact part holder is made of an electrically conductive material such as copper.

Der Kontaktteilhalter ist z.B. durch Stanzen und anschließendem Rollen hergestellt. Das elektrisch leitende Material, aus dem der Kontaktteilhalter besteht, wird auf einer Stanzmaschine beschnitten, vorgebogen und anschließend gerollt. Ein Trägerstreifen verbindet nach dem Rollen mehrere Kontaktteilhalter. Diese können auf eine Spule gewickelt werden, so daß sie leicht bis zur Weiterverarbeitung gelagert bzw. zu einem weiterverarbeitenden Betrieb ausgeliefert werden können.The contact part holder is e.g. produced by punching and then rolling. The electrically conductive material that makes up the contact part holder is cut on a punching machine, pre-bent and then rolled. A carrier strip connects after rolling a plurality of contact part holder. These can be wound on a spool, so that they can easily be stored until further processing or delivered to a further processing operation.

Ferner betrifft die Erfindung einen Federkontakt mit einer Feder, einem Kontaktteil und einem Kontaktteilhalter der obengenannten Art, wobei die Feder und das Kontaktteil in den zylindrischen Abschnitt des Kontaktteilhalters eingesetzt sind und sich die Feder an den Fortsätzen abstützt. Der Federkontakt kann z.B. in einem Gehäuse angebracht sein. In das Gehäuse kann dann ein Kontaktstift oder dergleichen eingebracht werden, der an das Kontaktteil angreift. Das Kontaktteil dient dann als Kontakt für den Kontaktstift, so daß eine elektrisch leitende Verbindung hergestellt ist. Der Federkontakt ist kompakt ausgebildet und kann selbst bei engen Platzverhältnissen, wie sie z.B. in Fahrzeugen vorliegen, eingesetzt werden. Ferner erfolgt der Zusammenbau des Federkontakts schnell, indem das Kontaktteil und die Feder in den zylindrischen Abschnitt des Kontaktteilhalters eingesetzt werden. Da der Kontaktteilhalter einstückig ausgebildet ist, entfällt ein zeitaufwendiger Zusammenbau des Kontaktteilhalters.Furthermore, the invention relates to a spring contact with a spring, a contact part and a contact part holder of the above type, wherein the spring and the contact part are inserted into the cylindrical portion of the contact part holder and the spring is supported on the extensions. The spring contact may e.g. be mounted in a housing. In the housing then a contact pin or the like can be introduced, which acts on the contact part. The contact member then serves as a contact for the contact pin, so that an electrically conductive connection is made. The spring contact is compact and can even in confined spaces, such as. in vehicles, are used. Further, the assembly of the spring contact is done quickly by the contact part and the spring are inserted into the cylindrical portion of the contact part holder.

  • FIG. 2 a perspective view of the mounted on a housing spring contact with the contact part holder.

Figur 1 zeigt einen Federkontakt 10 bestehend aus einem Kontaktteilhalter 12, einer Feder 14 und einem Kontaktteil 16. In Figur 2 ist dieser Federkontakt 10 im zusammengebauten Zustand und in ein Gehäuse 18 eingesetzt gezeigt. FIG. 1 shows a spring contact 10 consisting of a contact part holder 12, a spring 14 and a contact part 16. In FIG. 2 This spring contact 10 is shown in the assembled state and inserted into a housing 18.

Der Kontaktteilhalter 12, das aus einem elektrisch leitenden Material wie Kupfer besteht und mit einem Stromkreis verbunden werden kann, dient als Kontaktstück und ist einstückig ausgebildet.The contact part holder 12, which consists of an electrically conductive material such as copper and can be connected to a circuit, serves as a contact piece and is integrally formed.

An seinem bezüglich Figur 1 linken Ende hat der Kontaktteilhalter 12 einen zylindrischen Abschnitt 20, der der späteren Aufnahme der Feder 14 und des Kontaktteils 16 dient.At his re FIG. 1 left end of the contact part holder 12 has a cylindrical portion 20 which serves the later receiving the spring 14 and the contact part 16.

An den zylindrischen Abschnitt 20 anschließend hat der Kontaktteilhalter 12 abgewinkelte Fortsätze 22, an denen sich die Feder 14 im zusammengebautem Zustand des Federkontakts 10 abstützt. In den Figuren 1 und 2 sind drei Fortsätze 22 gezeigt, es könnten jedoch auch nur zwei oder mehr Fortsätze 22 sein oder auch ein abgewinkelter, umlaufender Rand, an dem sich die Feder 14 abstützt (nicht gezeigt).To the cylindrical portion 20 then the contact part holder 12 has angled projections 22, on which the spring 14 is supported in the assembled state of the spring contact 10. In the FIGS. 1 and 2 three extensions 22 are shown, but it could also be only two or more extensions 22 or an angled, circumferential edge on which the spring 14 is supported (not shown).

Das den Fortsätzen 22 entgegengesetzte Ende des zylindrischen Abschnitts 20 ist umgebogen. Dieses Umbiegen erfolgt, wie im weiteren erläutert ist, nach dem Einbringen der Feder 14 und des Kontaktteils 16. An das umgebogene Ende 26 kann sich das in den zylindrischen Abschnitt 20 eingesetzte Kontaktteil 16 anlehnen. Insbesondere kann das Kontaktteil 16 von der Feder 14 gegen das Ende 26 beaufschlagt werden.The projections 22 opposite end of the cylindrical portion 20 is bent. This bending takes place, as explained below, after the introduction of the spring 14 and the contact part 16. At the bent end 26, the inserted into the cylindrical portion 20 contact part 16 can lean against. In particular, the contact part 16 can be acted upon by the spring 14 against the end 26.

An den rohrförmigen Abschnitt 20 anschließend hat der Kontaktteilhalter 12 einen stegförmigen Abschnitt 27. An dem stegförmigen Abschnitt 27 ist ein Befestigungsbereich 24 ausgebildet, der an nicht gezeigte, vorgesehene Aussparungen im Gehäuse 18 angreifen kann, wodurch der Kontaktteilhalter 12 an dem Gehäuse 18 befestigt wird. Wenn der Federkontakt 10 in das Gehäuse 18 eingesetzt ist, greift der stegförmige Abschnitt 27 an die Innenwandung des Gehäuses 18 an (Figur 2).To the tubular portion 20 then the contact part holder 12 has a web-shaped portion 27. On the web-shaped portion 27, a mounting portion 24 is formed, which can engage, not shown, provided recesses in the housing 18, whereby the contact part holder 12 is fixed to the housing 18. When the spring contact 10 in the housing 18th is used, the web-shaped portion 27 engages the inner wall of the housing 18 ( FIG. 2 ).

Im zusammengebautem Zustand des Federkontakts 10 stützt sich die Feder 14, die hier eine spiralförmige Druckfeder ist, an den abgewinkelten Fortsätzen 22 des Kontaktteilhalters 12 ab. Die Feder 14 kann das Kontaktteil 16 gegen das umgebogene Ende 26 des zylindrischen Abschnitts 20 beaufschlagen.In the assembled state of the spring contact 10, the spring 14, which is here a helical compression spring, is supported on the angled extensions 22 of the contact part holder 12. The spring 14 can act on the contact part 16 against the bent end 26 of the cylindrical portion 20.

Das kappenförmige Kontaktteil 16, das in den zylindrischen Abschnitt 27 eingesetzt wird, hat eine Kontaktfläche 28, an die ein in das Gehäuse 18 eingesetzter Kontaktstift (nicht gezeigt) oder dergleichen angreifen kann. An die Kontaktfläche 28 schließt ein Bereich an, dessen Außendurchmesser dem Durchmesser der Kontaktfläche 28 entspricht. Ein der Kontaktfläche 28 entgegengesetzter Abschnitt des Kontaktteils 16 ist entsprechend dem umgebogenen Ende 26 des zylindrischen Abschnitts 20 ausgebildet und lehnt sich an dieses Ende 26 an, wenn es von der Feder 14 gegen dieses beaufschlagt wird.The cap-shaped contact part 16 which is inserted into the cylindrical portion 27 has a contact surface 28 to which a contact pin (not shown) or the like inserted in the housing 18 can engage. Adjoining the contact surface 28 is an area whose outer diameter corresponds to the diameter of the contact surface 28. A portion of the contact portion 16 opposite the contact surface 28 is formed corresponding to the bent end 26 of the cylindrical portion 20 and leans against this end 26 when urged by the spring 14 against it.

Das Kontaktteil 16 hat ferner einen solchen Durchmesser, daß es sich axial in dem zylindrischen Abschnitt 20 bewegen kann. Nach dem Umbiegen des Kontaktteilhalters 12 kann das Kontaktteil 16 jedoch nicht aus dem zylindrischen Abschnitt 20 gelangen.The contact part 16 further has a diameter such that it can move axially in the cylindrical portion 20. However, after bending over of the contact part holder 12, the contact part 16 can not get out of the cylindrical section 20.

Das Gehäuse 18, in das der Federkontakt 10 eingesetzt gezeigt ist (Figur 2), hat zwei unterschiedliche Innendurchmesser. Ein Durchmesser (gemäß Figur 2 gesehen rechts) ist so gewählt, daß der zylindrische Abschnitt 20 des Federkontakts 10 an diesem anliegt, während der zweite Innendurchmesser größer ist und einen Kontaktstift aufnehmen kann (nicht gezeigt).The housing 18 into which the spring contact 10 is shown inserted ( FIG. 2 ), has two different inner diameters. A diameter (according to FIG. 2 seen on the right) is chosen so that the cylindrical portion 20 of the spring contact 10 abuts this, while the second inner diameter is larger and can receive a contact pin (not shown).

In den Bereich mit dem größeren Durchmesser erstreckt sich ein Teil des zylindrischen Abschnitts 20 mit dem Kontaktteil 16. Ferner ist an der Wandung des Gehäuses 18 ein Kontakt angeordnet, der mit der Stromquelle verbunden ist und an dem der Kontaktstift angreifen kann. Eine Aussparung 30, die der späteren Verrastung des Kontaktstiftes dient, ist an der Wandung des Gehäuses 18 angeordnet.In the area with the larger diameter, a portion of the cylindrical portion 20 extends to the contact portion 16. Further, on the wall of the housing 18, a contact is arranged, which is connected to the power source and on which the contact pin can engage. A recess 30, which serves for the subsequent latching of the contact pin, is arranged on the wall of the housing 18.

Im folgenden wird auf die Herstellung des Kontaktteilhalters 12, den Zusammenbau des Federkontakts 10, auf das Einbringen desselben ins Gehäuse 18, sowie auf das Herstellen einer elektrischen Verbindung eingegangen.In the following, the manufacture of the contact part holder 12, the assembly of the spring contact 10, the introduction of the same into the housing 18, as well as the establishment of an electrical connection will be discussed.

Bei der Herstellung des Kontaktteilhalters 12 für einen Federkontakt 10 wird ein elektrisch leitendes Material auf einer Stanzmaschine beschnitten. Beim Biegen werden unter anderem der Befestigungsbereich 24 ausgeformt. Letztendlich wird das Zwischenteil gerollt, wobei der zylindrische Abschnitt 20 gebildet wird.In the manufacture of the contact part holder 12 for a spring contact 10, an electrically conductive material is cut on a punching machine. When bending Among other things, the fastening area 24 are formed. Finally, the intermediate part is rolled, whereby the cylindrical portion 20 is formed.

Mehrere fertig gestellte Kontaktteilhalter 12 sind dann an einem schematisch in Figur 1 gezeigten, einzelnen Trägerstreifen 32 angebunden, der am bezüglich Figur 1 rechten Ende des stegförmigen Abschnitts 27 vorgesehen ist. Aufgrund dieses Trägerstreifens 32 können die miteinander verbundenen Kontaktteilhalter 12 zu einer Spule aufgewickelt werden. Aufgewickelt werden die miteinander verbundenen Kontaktteilhalter 12 bis zur Weiterverarbeitung gelagert bzw. an einen weiterverarbeitenden Betrieb ausgeliefert.Several finished contact part holder 12 are then at a schematic in FIG. 1 shown, individual carrier strip 32 connected to the respect FIG. 1 right end of the web-shaped portion 27 is provided. Due to this carrier strip 32, the interconnected contact part holder 12 can be wound into a coil. Wound up, the interconnected contact part holders 12 are stored until further processing or delivered to a further processing operation.

Beim Zusammenbau des Federkontakts 10 werden die Feder 14 und das kappenförmige Kontaktteil 16 auf eine Montagevorrichtung zugeführt und in den zylindrischen Abschnitt 20 des Kontaktteilhalters 12 eingesetzt. Dieses Einsetzen erfolgt von dem in Figur 2 gesehenen linken Ende, wobei zuerst die Feder 14 und dann das Kontaktteil 16 eingesetzt wird. Nach dem Einsetzen der beiden Teile wird der Kontaktteilhalter 12 am bezüglich Figur 2 linken Ende umgebogen. Die Feder 14, die sich an den abgewinkelten Fortsätzen 22 abstützt, beaufschlagt dann das Kontaktteil 16 gegen das umgebogene Ende 26. Die zusammengebauten Federkontakte 10 sind noch immer mit dem Trägerstreifen 32 untereinander verbunden und können wiederum als Spule aufgewickelt werden.When assembling the spring contact 10, the spring 14 and the cap-shaped contact part 16 are fed to a mounting device and inserted into the cylindrical portion 20 of the contact part holder 12. This insertion is made by the in FIG. 2 seen left end, wherein first the spring 14 and then the contact member 16 is inserted. After insertion of the two parts of the contact part holder 12 is relative to FIG. 2 bent over left end. The spring 14, which is supported on the angled projections 22, then acts on the contact member 16 against the bent end 26. The assembled spring contacts 10 are still connected to the carrier strip 32 with each other and in turn can be wound up as a coil.

Nach dem Durchtrennen des Trägerstreifens 32 wird der Federkontakt 10 von (bezüglich Figur 2) rechts in das Gehäuse 18 eingebracht, wobei ein Teil des zylindrischen Abschnitts 20 in den Bereich des Gehäuses 18 mit dem größeren Durchmesser ragt. Der Befestigungsbereich 24 befestigt den Federkontakt 10, in dem er an eine nicht gezeigte Aussparung im Gehäuse 18 angreift.After severing the carrier strip 32, the spring contact 10 of (with respect FIG. 2 ) is inserted into the housing 18 on the right, with part of the cylindrical portion 20 projecting into the area of the housing 18 with the larger diameter. The mounting portion 24 secures the spring contact 10, in which it engages a recess, not shown, in the housing 18.

Der Trägerstreifen 32 kann auch nach dem Einbringen des Federkontaktes 10 in das Gehäuse 18 durchtrennt werden.The carrier strip 32 can also be severed after the introduction of the spring contact 10 into the housing 18.

Zur Herstellung einer elektrischen Verbindung wird der nicht gezeigte Kontaktstift von der bezüglich Figur 2 linken Seite eingeführt. Damit der Kontaktstift in die Aussparung 30 im Gehäuse 18 einrasten kann, wird das Kontaktteil 16 gegen die Feder 14 gedrückt und der Kontaktstift gedreht, bis dieser in die Aussparung 30 einrastet. Das Kontaktteil 16 wird von der Feder 14 so gegen den Kontaktstift beaufschlagt, daß die Kontaktfläche 28 an den Kontaktstift angreift, wodurch eine elektrische Verbindung hergestellt ist. Aufgrund der Bajonettverbindung zwischen dem Kontaktstift und dem Gehäuse 18 kann sich der Kontaktstift nicht unbeabsichtigt lösen.For the preparation of an electrical connection, the contact pin, not shown, of the respect FIG. 2 left side introduced. So that the contact pin can engage in the recess 30 in the housing 18, the contact part 16 is pressed against the spring 14 and the contact pin is rotated until it engages in the recess 30. The contact member 16 is acted upon by the spring 14 against the contact pin, that the contact surface 28 engages the contact pin, whereby an electrical connection is made. Due to the Bayonet connection between the contact pin and the housing 18, the contact pin can not solve unintentionally.
