Description

Die Erfindung geht aus von einem Kontaktelement, das auf einer Steckseite einen Steckkontaktabschnitt zum Zusammenstecken mit einem Gegenkontaktelement und auf einer Anschlußseite einen Anschlußabschnitt mit einem zur Verbindung mit einem elektrischen Leiter geeigneten Aufbau aufweist, wobei ein Abschnitt an seiner dem anderen Abschnitt zugewandten Seite ein zu dem anderen Abschnitt gerichtetes Verbindungselement aufweist und der andere Abschnitt mit einer Aufnahme für das Verbindungselement ausgebildet ist.The invention is based on a contact element which has a plug-in contact section on a plug-in side for mating with a mating contact element and a connection section on a connection side with a structure suitable for connection to an electrical conductor, with a section on its side facing the other section facing the one has another section directed connecting element and the other section is formed with a receptacle for the connecting element.

Ein derartiges Kontaktelement, bei dem ein am Steckkontaktabschnitt gegenüber der Längsachse versetzt angeordneter Schaft eine Quetschverbindung mit der Aufnahme am Anschlußabschnitt ausbildet, ist aus EP-A-0 240 642 bekannt.Such a contact element, in which a shaft arranged offset on the plug-in contact section with respect to the longitudinal axis forms a crimp connection with the receptacle on the connection section, is known from EP-A-0 240 642.

Bei einem solchen Kontaktelement ist es erwünscht, den Steckkontaktabschnitt und den Anschlußabschnitt möglichst optimal an ihren jeweiligen Verwendungszweck anzupassen. So ist z.B. der Steckkontaktabschnitt häufig mit Kontaktfedern versehen, die aus einem Material bestehen müssen, das ausreichende Federeigenschaften aufweist. Andererseits soll der Anschlußabschnitt z.B. aus einem Material bestehen, das z.B. gut mit Lot benetzbar oder ausreichend verformbar ist, wodurch das Ancrimpen von Leitern an eine Crimp-Hülse des Anschlußabschnittes begünstigt wird.With such a contact element, it is desirable to adapt the plug contact section and the connecting section as optimally as possible to their respective intended use. For example, the plug-in contact section is often provided with contact springs which must be made of a material which has sufficient spring properties. On the other hand, the connection section e.g. consist of a material that e.g. is easily wettable with solder or is sufficiently deformable, which favors the crimping of conductors onto a crimp sleeve of the connection section.

Aufgabe vorliegender Erfindung ist es daher, ein Kontaktelement der eingangs genannten Art so auszubilden, daß Anschluß- und Steckkontaktabschnitt des Kontaktelementes je für sich aus dem jeweils bestgeeigneten Material hergestellt werden können.The object of the present invention is therefore to design a contact element of the type mentioned at the outset in such a way that the connection and plug-in contact section of the contact element can each be produced from the most suitable material in each case.

Erfindungsgemäß ergibt sich die Lösung dieser Aufgabe dadurch, daß das Verbindungselement als zu einer Längsachse des Kontaktelementes koaxialer Bolzen und die Aufnahme des anderen Abschnittes als dem Bolzen angepaßte Bohrung ausgebildet ist, und daß Anschluß- und Steckkontaktabschnitt durch Eindrücken des Bolzens in die Bohrung mit Preßpassung dieser Teile zusammengefügt sind.According to the invention, this object is achieved in that the connecting element is designed as a coaxial bolt to a longitudinal axis of the contact element and the receptacle of the other section is adapted to the bolt, and that the connecting and plug-in contact section are pressed together by pressing the bolt into the bore with an interference fit of these parts.

Dabei kann auch der Bolzen dem Anschlußabschnitt und die Bohrung dem Steckkontaktabschnitt zugeordnet sein.The bolt can also be assigned to the connection section and the bore to the plug contact section.

Weiter kann vorgesehen sein, daß zwischen Anschluß- und Steckkontaktabschnitt ein als gesondert handhabbares Teil ausgebildetes Zwischenstück vorgesehen ist, und daß das Zwischenstück auf einer Seite eine dem Bolzen angepaßte Bohrung und auf seiner anderen Seite einen in die Bohrung des Anschluß- oder Steckkontaktabschnittes passenden Bolzen aufweist.It can further be provided that between the connection and plug-in contact section there is provided an intermediate piece designed as a separately manageable part, and that the intermediate piece has on one side a bore adapted to the bolt and on its other side a bolt which fits into the bore of the connection or plug-in contact section .

Dieser Aufbau eines Kontaktelementes ist dann besonders vorteilhaft, wenn das Kontaktelement besonders lang sein soll oder einen komplizierten Aufbau aufweist. Für das Zwischenstück kann dann ein vom Material des Anschluß- und Steckkontaktabschnittes abweichendes Material gewählt werden.This structure of a contact element is particularly advantageous if the contact element is to be particularly long or has a complicated structure. A material different from the material of the connection and plug contact section can then be selected for the intermediate piece.

Ferner kann vorgesehen sein, daß ein zwischen Anschlußabschnitt und Steckkontaktabschnitt vorgesehenes Zwischenstück auf den Bolzen aufschiebbar ausgebildet ist.It can further be provided that an intermediate piece provided between the connection section and the plug contact section is designed to be slidable onto the bolt.

Das aufschiebbare Zwischenstück ermöglicht es vorteilhaft, dieses sonst mit dem Anschlußabschnitt einstückig ausgebildete Teil auch dann als relativ einfach herstellbares Drehteil zu gestalten, wenn der Anschlußabschnitt selbst nicht als Drehteil ausgebildet werden kann. Im übrigen dient das Zwischenstück dazu, um zwischen Anschluß- und Steckkontaktabschnitt eine nutartige Vertiefung zu schaffen, die z.B. den Bohrungsrand einer Frontplatte aufnimmt, an der das Kontaktelement festgelegt werden soll.The push-on intermediate piece advantageously makes it possible to design this part, which is otherwise formed in one piece with the connecting section, as a relatively simple to produce rotating part even if the connecting section itself cannot be designed as a rotating part. Furthermore the intermediate piece serves to create a groove-like depression between the connection and plug-in contact section, which, for example, receives the edge of the bore of a front plate on which the contact element is to be fixed.

Schließlich kann noch vorgesehen sein, daß jeder Bolzen eines Steckkontakt- oder Anschlußabschnittes zumindest den gleichen Außendurchmesser aufweist.Finally, it can also be provided that each bolt of a plug contact or connection section has at least the same outside diameter.

Auf diese Weise ergibt sich der Hauptvorteil des Kontaktelementes nach der Erfindung, nämlich, daß unterschiedlich gestaltete Anschluß- und Steckkontaktabschnitte beliebig zu einem dem jeweiligen Verwendungszweck angepaßten Kontaktelement zusammengefügt werden können, wodurch die Zahl der vorrätig zu haltenden Teile wesentlich reduziert werden kann.In this way, there is the main advantage of the contact element according to the invention, namely that differently shaped connection and plug contact sections can be combined as desired for a contact element adapted to the respective intended use, as a result of which the number of parts to be kept in stock can be significantly reduced.

Für das Zusammenfügen von Bolzen und Bohrung ist es auch noch vorteilhaft, daß jeder Bolzen mit einer umfangseitigen Rändelung versehen ist.For the joining of the bolt and the bore, it is also advantageous that each bolt is provided with a knurling on the circumference.

Ausführungsbeispiele von Kontaktelementen nach der Erfindung werden nachfolgend anhand von drei Figuren noch näher erläutert.Exemplary embodiments of contact elements according to the invention are explained in more detail below with reference to three figures.

Dabei zeigen, jeweils stark vergrößert, in Seitenansicht und teilweise geschnitten dargestellt,

  • FIG 1 ein Kontaktelement, das auf seiner Steckkontaktseite als Kontaktstift und auf seiner Anschlußseite als Lötanschluß ausgebildet ist,
  • FIG 2 ein Kontaktelement, das auf seiner Steckkontaktseite als Kontaktbuchse mit Kontaktfedern und auf seiner Anschlußseite als Crimphülse zum Ancrimpen eines Drahtes ausgebildet ist, und
  • FIG 3 ein Kontaktelement, das auf seiner Steckkontaktseite als Kontaktbuchse mit Kontaktfedern und auf seiner Anschlußseite mit in Bohrungen einer Leiterplatte einsteckbaren Anschlußstiften versehen ist.
Show, each greatly enlarged, shown in side view and partially in section,
  • 1 shows a contact element which is designed on its plug contact side as a contact pin and on its connection side as a solder connection,
  • 2 shows a contact element which is formed on its plug contact side as a contact socket with contact springs and on its connection side as a crimp sleeve for crimping a wire, and
  • 3 shows a contact element which is provided on its plug-in contact side as a contact socket with contact springs and on its connection side with plug-in pins which can be inserted into holes in a printed circuit board.

Im einzelnen ist den Figuren zu entnehmen, daß jedes Kontaktelement auf einer zur Kontaktgabe mit einem Gegenkontaktelement vorgesehenen Seite einen Steckkontaktabschnitt 1 aufweist, der als Kontaktstift 2 oder Kontaktbuchse 3 mit Kontaktfedern 4 ausgebildet sein kann.In detail, it can be seen from the figures that each contact element has a plug-in contact section 1 on a side provided for making contact with a mating contact element, which can be designed as a contact pin 2 or contact socket 3 with contact springs 4.

Konzentrisch zu einer Längsachse 5 von Stift 2 oder Buchse 3 weist jeder Steckkontaktabschnitt 1 einen zylindrischen Bolzen 6 auf, der vom Steckkontaktabschnitt 1 entgegengesetzt zu einem freien Ende 7 von Stift 2 oder Buchse 3 absteht.Concentric to a longitudinal axis 5 of pin 2 or socket 3, each plug contact section 1 has a cylindrical bolt 6 which projects from plug contact section 1 opposite to a free end 7 of pin 2 or socket 3.

Ein zur Verbindung mit einem elektrischen Leiter, wobei dieser Leiter auch die Leiterbahn einer Leiterplatte sein kann, vorgesehener Anschlußabschnitt 8 des Kontaktelements ist mit einer Bohrung 9 versehen, die so bemessen ist, daß der Bolzen 6 im Preßsitz parallel zur Achse 5 in diese Bohrung eingedrückt werden kann. Eine umfangseitige Rändelung 10 des Bolzens verbessert dabei die Preßpassung zwischen Anschlußabschnitt 8 und Steckkontaktabschnitt 1 des Kontaktelementes.A connection section 8 of the contact element provided for connection to an electrical conductor, which conductor can also be the conductor track of a printed circuit board, is provided with a bore 9 which is dimensioned such that the bolt 6 is pressed into this bore parallel to the axis 5 in a press fit can be. A circumferential knurling 10 of the bolt improves the interference fit between the connection section 8 and the plug contact section 1 of the contact element.

Der Bolzen 6 ist, unabhängig davon, wie die kontaktgebenden Teile des Steckkontaktabschnittes 1 ausgebildet sind, bei allen Kontaktelementen zumindest im Durchmesser gleich ausgebildet, so daß zur Herstellung eines Kontaktelementes beliebige Anschlußabschnitte 8 mit beliebigen Steckkontaktabschnitten 1 zusammengefügt werden können.The bolt 6, regardless of how the contact-making parts of the plug-in contact section 1 are designed, is of at least the same diameter in all contact elements, so that any connecting sections 8 can be joined with any plug-in contact sections 1 for producing a contact element.

Wie Figur 3 zeigt, kann anstelle eines mit dem Anschlußabschnitt 8 einstückigen Zwischenstückes 11 das Zwischenstück auch als ein auf den Bolzen 6 aufschiebbares, ringförmiges Teil 18 ausgebildet sein, wobei das Zwischenstück 11 insbesondere dazu dient, um zwischen dem Steckkontaktabschnitt 1 und dem Zwischenstück 11 ein ringförmiges federndes Rastelement 13 zu halten, das zusammen mit dem Anschlußabschnitt 8 eine ringförmige Nut 12 bildet, in der z.B. ein Rand einer Bohrung in einer Frontplatte oder Gehäusewand 17 aufgenommen werden kann. Das Rastelement 13 dient dabei zur rastenden Fixierung des Kontaktelementes an der Frontplatte oder Gehäusewand 17.As FIG. 3 shows, instead of an intermediate piece 11 integral with the connecting section 8, the intermediate piece can also be designed as an annular part 18 that can be pushed onto the bolt 6, the intermediate piece 11 serving in particular to insert between the plug contact section 1 and the intermediate piece 11 to hold annular resilient locking element 13 which, together with the connection section 8, forms an annular groove 12 in which, for example an edge of a bore can be received in a front panel or housing wall 17. The latching element 13 is used for the latching fixation of the contact element on the front plate or housing wall 17.

In der oberen Hälfte von Figur 3 ist gezeigt, daß das Zwischenstück auch als Zwischenabschnitt 14 ausgebildet sein kann.In the upper half of Figure 3 it is shown that the intermediate piece can also be designed as an intermediate section 14.

Der Zwischenabschnitt 14 ist mit einer hohlzylindrischen Bohrung 15 versehen, in die der Bolzen 6 im Preßsitz eingefügt werden kann. Auf der vom Steckkontaktabschnitt 1 abgewandten Seite ist der Zwischenabschnitt 14 außen dem Bolzen 6 entsprechend ausgebildet, wobei dieser als Steckzylinder 16 in die Bohrung 9 im Preßsitz einfügbare Teil des Zwischenabschnittes 14 einen anderen, in aller Regel größeren Durchmesser hat, als der Bolzen 6.The intermediate section 14 is provided with a hollow cylindrical bore 15 into which the bolt 6 can be inserted in a press fit. On the side facing away from the plug-in contact section 1, the intermediate section 14 is formed on the outside corresponding to the bolt 6, this part of the intermediate section 14 which can be inserted into the bore 9 in the press fit as a plug-in cylinder 16 having a different, generally larger diameter than the bolt 6.

Der Zwischenabschnitt 14 kann dazu dienen, um den Abstand zwischen Steckkontaktabschnitt 1 und Anschlußabschnitt 8 zu vergrößern, oder um den für alle Steckkontaktabschnitte 1 gleichen Durchmesser der Bolzen 6 an eine im Durchmesser demgegenüber größere Bohrung 9 eines Anschlußabschnittes 8 anzupassen.The intermediate section 14 can serve to increase the distance between the plug contact section 1 and the connection section 8, or to adapt the diameter of the bolts 6, which is the same for all plug contact sections 1, to a larger diameter bore 9 of a connection section 8.
