Abstract
Description
Die Erfindung bezieht sich auf eine Kontaktbuchse für elektrische Steckverbinder, welche aus einen stabilen aus einem Blechmaterial gebildeten Hülsenkörper und einer in diesem einliegenden, eine Vielzahl mit einem in die Buchse einzuführenden Kontaktstift in linienförmigen oder streifenförmigen Kontakt tretender Kontaktierungsmitteln, wie Kontaktdrähte oder Kontaktstreifen aufweisenden, Kontaktfederbuchse besteht, wobei die Kontaktdrähte oder Kontaktstreifen der Kontaktfederbuchse um die Buchsenachse verdreht ausgerichtet und beidendig mit einem Randstreifen aus Blechmaterial verbunden sind, und wobei ferner die Kontaktfederbuchse mechanisch und elektrisch mit dem Hülsenkörper verbunden ist.The invention relates to a contact socket for electrical connectors, which from a stable sleeve body formed from a sheet material and one lying in it, a plurality with one to be inserted into the socket Contact pin in line-shaped or strip-shaped contacting contacting means, such as contact wires or contact strips, contact spring bushing there is, the contact wires or contact strips of the contact spring bushing aligned around the socket axis and at both ends with a Edge strips of sheet metal are connected, and furthermore the contact spring bush is mechanically and electrically connected to the sleeve body.
Solche, vielfach auch als Drahtfeder-bzw. Lamellenfeder-Kontaktbuchsen bezeichnete
Kontaktbuchsen sind an sich bekannt und zeichnen sich zum einen durch besonders
hervorragende Kontaktierungseigenschaften und zum anderen durch eine
wirtschaftliche Herstellbarkeit aus.
Eine erste bekannte Bauart einer solchen Kontaktbuchse zeichnet sich dadurch
aus, daß die Kontaktfederbuchse eine Anzahl von Kontaktstreifen aufweist, welche
insgesamt schräg zur Längsachse der Kontaktfederbuchse ausgerichtet sind. Charakteristisch
für Kontaktbuchsen dieser Ausgestaltung ist der Umstand, daß
deren Kontaktfederbuchsen eine Anzahl von streifenförmigen Kontaktierungsmitteln
aufweisen, die aus einer Anzahl durch Ausstanzen eines fortlaufenden Streifens
eines Kontaktmaterials gebildeten und am oberen und unteren Ende der
Kontaktfederbuchse über Randstreifen untereinander verbunden bleibenden Kontaktstreifen
gebildet sind. Im Zusammenhang mit der Anwendung aus einem Kontaktmaterial
freigeschnittener streifenförmiger Kontaktierungsmittel ist es ferner
bekannt die mittels entsprechender Ausstanzungen aus einem fortlaufenden Materialstreifen
hergestellten und zu einer Kontaktfederbuchse bzw. einer Kontaktierungsauskleidung
eines stabilen Hülsenkörpers gerollten Zuschnitte entlang
schräger Schnittlinien vom fortlaufenden Materialstreifen abzulängen und die beiden
Schnittkanten des die Kontaktfederbuchse bildenden Zuschnittes dann entlang
einer schräg zur Buchsenachse ausgerichteten Verbindungslinie miteinander zu
verbinden, um eine schräg zur Buchsenachse ausgerichtete bzw. um die Buchsenachse
tordiert ausgerichtete Anordnung der streifenförmigen Kontaktierungen
zu erreichen.Such, often also as wire spring or. Lamellar spring contact sockets are known per se and are distinguished on the one hand by particularly excellent contacting properties and on the other hand by their economical producibility.
A first known type of such a contact socket is characterized in that the contact spring socket has a number of contact strips, which are aligned obliquely to the longitudinal axis of the contact spring socket. Characteristic of contact bushes of this configuration is the fact that their contact spring bushings have a number of strip-shaped contacting means which are formed from a number of contact strips formed by punching out a continuous strip of contact material and remaining connected to one another at the upper and lower ends of the contact spring bushing via edge strips. In connection with the use of strip-shaped contacting means cut free from a contact material, it is also known to cut the blanks along oblique cutting lines from the continuous material strip by means of corresponding punchings from a continuous material strip and rolled them into a contact spring bushing or a contacting lining of a stable sleeve body, and to cut the two cutting edges of the die Then connect the contact spring bushing-forming blank along a connecting line oriented obliquely to the socket axis in order to achieve an arrangement of the strip-shaped contacts oriented obliquely to the socket axis or twisted around the socket axis.
Alle derartigen Kontaktbuchsen für elektrische Steckverbinder haftet ein gewisser Nachteil dahingehend an, daß es verhältnismäßig aufwendig ist die vergleichsweise labile Kontaktfederbuchse mit einem stabilen Hülsenkörper zu einer verwendbaren Kontaktbuchse zu verbinden, ohne die Kontaktierungseigenschaften der Kontaktfederbuchse nachteilig zu beeinträchtigen.All such contact sockets for electrical connectors are liable to a certain extent Disadvantage in that it is relatively expensive unstable contact spring bushing with a stable sleeve body to a usable one To connect the contact socket without the contacting properties of the contact spring socket adversely affect.
Der Erfindung liegt daher die Aufgabe zugrunde eine preisgünstig herstellbare Kontaktbuchse der eingangs beschriebenen Bauart für elektrische Steckverbinder aufzuzeigen, welche auf der einen Seite eine sichere Verankerung der Kontaktfederbuchse in dem stabilen Hülsenkörper gewährleistet und auf der anderen Seite auch in der mechanischen Serienfertigung leicht zu verwirklichen ist.The invention is therefore based on the object of producing at low cost Contact socket of the type described at the beginning for electrical connectors to show which on one side a secure anchoring of the contact spring bush guaranteed in the stable sleeve body and on the other side is also easy to implement in mechanical series production.
Diese Aufgabe wird ausgehend von einer Kontaktbuchse nach dem Oberbegriff des Anspruches 1 erfindungsgemäß im Wesentlichen dadurch gelöst, daß der Hülsenkörper mit wenigstens einem quer zur Längsachse der Kontaktbuchse gerichteten und mindestens durch eine Ausprägung gebildeten Vorsprung versehen ist, welcher mit einem der beiden die Kontaktdrähte oder Kontaktstreifen der Kontaktfederbuchse untereinander verbindenden Randstreifen aus Blechmaterial im formschlüssigen Eingriff steht. This task is based on a contact socket according to the generic term of claim 1 according to the invention essentially solved in that the sleeve body with at least one directed transversely to the longitudinal axis of the contact socket and is provided with at least one protrusion, which with one of the two the contact wires or contact strips of the contact spring socket interconnecting edge strips made of sheet metal in a form-fitting manner Intervention stands.
Die erfindungsgemäß rein formschlüssige Verbindungsweise von Kontaktfederbuchse und stabilen Hülsenkörper zeichnet sich zunächst durch den Vorzug aus, daß eine kontaktsichere Verbindung entsteht und trotzdem auf alle wärmetechnischen Verbindungsweisen, wie Schweißen oder Löten und dergl. mehr, zum gegenseitigen Verbinden von Kontaktfederbuchse und stabilen Hülsenteil verzichtet werden kann und daß daher auch kein Wärmeverzug oder ähnliche unerwünschten Erscheinungen auftreten können. Weiterhin gestattet die rein mechanischformschlüssige Festlegung der Kontaktfederbuchse im stabilen Hülsenkörper eine einfache Herstellung der Kontaktbuchse insgesamt unter ausschließlicher Anwendung von Schneid-und Formwerkzeugen, was einer Fertigung der Kontaktbuchsen aus fortlaufenden Materialstreifen sehr entgegenkommt, insbesondere dahingehend, daß mittels eines Stanz-und/oder Schneidwerkzeuges aus einem fortlaufenden Materialstreifen mit einem Crimpteil zum Anschluß der Kontaktbuchse an einen Einzelleiter einteilig Kontaktfederbuchsen freigeschnitten und freigestanzt und anschließend bereichsweise mehr oder minder vollständig eingerollt werden können, in der Weise, daß die die Kontaktfederbuchsen bildenden Bereiche der Freischnitte zu einem Zylinderkörper eingerollt und die die Crimpteile bildenden Bereiche der Freischnitte lediglich zu einem beispielsweise U-förmigen Profilquerschnitt gebogen werden können. Die solcherart vorgefertigten Kontaktfederbuchsen werden dann unbeschadet der Beibehaltung ihrer Verbindung mut einem Transportstreifen in einer mechanischen herstellbaren, formschlüssigen Weise durch gegenseitiges Verkrallen oder Verzahnen von Freischnitten und Widerlagern mit ihrerseits durch Ablängen und Einrollen eines Blechmatterials vorgefertigten stabilen Hülsenkörpern zu einer brauchbaren Kontakthülse verbunden, wobei die Freischnitte vorzugsweise aber nicht ausschließlicherweise in dem stabilen Hülsenkörper und die Widerlager entsprechend an der Kontaktfederbuchse angeordnet bzw. ausgebildet sind. Selbstverständlich liegt auch die Umkehrung dieser wechselweisen Anordnung von Freischnitten und Widerlagern im Bereich der vorliegenden Erfindung. The purely positive connection of the contact spring bushing according to the invention and stable sleeve body is initially characterized by the preference, that a contact-safe connection is created and still on all thermal engineering Connection methods, such as welding or soldering and the like, for mutual purposes Connection of contact spring bushing and stable sleeve part dispensed with can be and therefore no heat distortion or similar undesirable Phenomena can occur. Furthermore, the purely mechanical form-fit permits Fixing the contact spring bushing in a stable sleeve body simple manufacture of the contact socket overall with exclusive use of cutting and shaping tools, which means manufacturing the contact sockets very accommodating from continuous strips of material, especially in that that by means of a punching and / or cutting tool from a continuous Material strips with a crimp part for connecting the contact socket to a Single conductor one-piece contact spring bushings cut and punched and can then be rolled up more or less completely in some areas, in such a way that the areas of the cutouts forming the contact spring bushings rolled into a cylinder body and the areas forming the crimp parts the free cuts only to a U-shaped profile cross section, for example can be bent. The prefabricated contact spring bushings are then without prejudice to the maintenance of their connection by means of a transport lane in a mechanically producible, form-fitting manner by mutual Clawing or interlocking free cuts and abutments with them Pre-made stable by cutting and rolling a sheet metal material Sleeve bodies connected to a usable contact sleeve, the free cuts but preferably not exclusively in the stable sleeve body and the abutments are arranged accordingly on the contact spring bush or are trained. Of course, the reversal of this is alternate Arrangement of free cuts and abutments in the area of the present Invention.
In einer ersten Verwirklichungsform einer aus einer Kontaktfederbuchse und einem stabilen Hülsenkörper bestehenden Kontaktbuchse ist vorgesehen, daß die Kontaktierungsmittel der Kontaktfederbuchse aus einer aus einem fortlaufenden Bandmaterial freigestanzten Kontaktstreifenfolge bestehen und untereinander beidendig über Randstreffen des fortlaufenden Bandmaterials untereinander verbunden sowie in gleichbleibenden gegenseitigen Abständen gehalten sind und daß der Hülsenkörper zwei in axialer Richtung zueinander beabstandete Ausprägungen aufweist deren jede mit jeweils einem der beiden die Kontaktstreifen beidendig untereinander verbindenden Randstreifen im formschlüssigen Eingriff steht. Dabei kann im Einzelnen weiter noch vorgesehen sein, daß die radial zu dessen Längsachse gerichteten Vorsprünge des Hülsenkörpers durch zungenförmige nach innen durchgestellte Freischnitte gebildet sind und jeweils in eine Lücke zwischen benachbarten Kontaktstreifen der Kontaktfederbuchse eingreifend formschlüssig am inneren Rand der die Kontaktstreifen beidendig untereinander verbindenden Randstreifen anliegen.In a first embodiment, one of a contact spring bushing and one stable sleeve body existing contact socket is provided that the contacting means the contact spring bushing from a continuous Tape material punched out contact strip sequence exist and mutually at both ends connected to each other via marginal meetings of the continuous strip material and are held at constant mutual intervals and that the sleeve body two forms spaced apart in the axial direction each with one of the two, the contact strips at both ends interconnecting edge strips is in positive engagement. there can be further provided in detail that the radial to its longitudinal axis directed projections of the sleeve body through tongue-shaped inwards through cuts are formed and each in a gap between adjacent Contact strips of the contact spring bush engaging form-fitting on inner edge of the contact strips connecting the two at each other Edge strips are in contact.
Gemäß einer zweiten Verwirklichungsform einer aus einer Kontaktfederbuchse und einem stabilen Hülsenkörper bestehenden Kontaktbuchse kann aber auch vorgesehen sein, daß mindestens einer der beiden die Kontaktstreifen der Kontaktfederbuchse beidendig untereinander verbindenden Randstreifen mit einer Fensterausnehmung versehen ist und der Hülsenkörper wenigstens eine freigeschnittene und mit der Fensterausnehmung im formschlüssigen Eingriff stehende Zunge aufweist.According to a second embodiment, one of a contact spring bushing and a stable sleeve body existing contact socket can also be provided be that at least one of the two the contact strips of the contact spring bushing edge strips connecting at both ends with a window recess is provided and the sleeve body at least one cut free and has tongue with the window recess in positive engagement.
Die Fensterausnehmung ist vorteilhafterweise in dem dem freien Ende der Kontaktbuchse gegenüberliegenden Randstreifen angeordnet und in Umfangsrichtung der Kontaktfederbuchse ausgerichtet, so daß die formschlüssige Verbindung zwischen Kontaktfederbuchse und stabilem Hülsenkörper zum Bereich des Anschlusses der Kontaktbuchse an den Einzelleiter hin verlagert ist. The window recess is advantageously in the free end of the contact socket opposite edge strips arranged and in the circumferential direction the contact spring bush aligned so that the positive connection between Contact spring bush and stable sleeve body to the area of the connection the contact socket is shifted towards the single conductor.
Eine vorteilhafte Gestaltungsweise der formschlüssigen Verbindung der Kontaktfederbuchse mit dem Stabilen Hülsenkörper besteht darin, daß die in dem dem freien Ende der Kontaktbuchse gegenüberliegenden Randstreifen der Kontaktfederbuchse angeordnete Fensterausnehmung eine rechteckige Grundrißform aufweist und im Hülsenkörper zwei einander gegenüberliegende und nach innen abgewinkelte Zungen freigeschnitten sind, welche mit den Schmalseiten der Fensterausnehmung im formschlüssigen Eingriff stehen. Diese Ausbildung ist insbesondere dort von besonderem Vorteil, wo im Weiteren vorgesehen ist, daß die beiden im Hülsenkörper freigeschnittenen Zungen gegeneinander zeigend ausgerichtet und jede der beiden Zungen in einen der beiden Längsränder des den Hülsenkörper bildenden Blechmaterialzuschnittes auslaufend freigeschnitten ist.An advantageous design of the positive connection of the contact spring bush with the stable sleeve body is that in which the free Edge of the contact spring bush opposite the end of the contact bush arranged window recess has a rectangular plan shape and in the sleeve body two opposite and angled inwards Tongues are cut free, which with the narrow sides of the window recess to be in positive engagement. This training is particularly there of particular advantage, where it is further provided that the two in the sleeve body cut out tongues pointing towards each other and each of the two tongues in one of the two longitudinal edges of the one forming the sleeve body Sheet material blank is cut free expiring.
In weiterer vorteilhafter Ausgestaltung wird noch vorgeschlagen, daß die Stoßränder des die Kontaktfederbuchse bildenden Materialzuschnittes und des den Hülsenkörper bildenden Materialzuschnittes um wenigstens 45° gegeneinander verdreht angeordnet sind.In a further advantageous embodiment, it is also proposed that the abutting edges of the material blank forming the contact spring bushing and of the sleeve body forming material cut rotated against each other by at least 45 ° are arranged.
