Abstract
Description
Die Erfindung bezieht sich auf eine Kontaktstift-Kontaktfederbuchsen-Baueinheit, bei der der Kontaktstift zwei etwa parallele, ein durch Ausstanzen gebildetes Langloch begrenzende, aufeinanderzu federnde, dem Einpressen in eine Öffnung einer Leiterplatte dienende Schenkel aufweist, denen eine der Begrenzung des Einsteckweges dienende Schulter eines Trägerteils zugeordnet ist, und bei der die Kontaktfederbuchse eine Vielzahl von Kontaktfedern umfaßt, die sich etwa vom Bereich der Schulter des Trägerteils ausgehend im Abstand von der Buchsenachse zum Bereich der vorderen Stifteinführungsöffnung hin erstrecken und etwa in ihrem mittleren Bereich den kleinsten Abstand von der Buchsenachse aufweisen.The invention relates to a contact pin-contact spring socket assembly, in which the contact pin has two approximately parallel, a slot formed by punching oblong, mutually resilient, serving for pressing into an opening in a circuit board, one of which serves to limit the insertion path shoulder one Carrier part is assigned, and in which the contact spring bushing comprises a plurality of contact springs, which extend approximately from the region of the shoulder of the carrier part at a distance from the socket axis to the region of the front pin insertion opening and have the smallest distance from the socket axis in their central region .
Bei einer bekannten Kontaktstift-Kontaktfederbuchsen-Baueinheit dieser Art gemäß einer früheren Anmeldung gemäß DE-A-39 15 644.3 (dieses Dokument fällt unter Art. 54(3) EPÜ) ist der Kontaktstift als mit dem Trägerteil, das die der Begrenzung des Einsteckweges dienende Schulter aufweist, einstückiges Bauelement ausgebildet. Dieses wird zunächst als Drehteil hergestellt, das die Schulter und einen von dieser vorstehenden Kontaktstiftabschnitt umfaßt, aus dem nach Abfräsen des auf beiden Seiten überflüssigen Materials und damit Überführung in eine flache Form in einem folgenden Stanzvorgang das Langloch ausgestanzt wird. Stattdessen ist es auch möglich, von einem Kontaktblechbandmaterial mit zwei Bandbereichen unterschiedlicher Stärke auszugehen, und zwar einem Bereich mit einer dem Durchmesser der Schulter entsprechenden Stärke und einem Bereich mit einer der gewünschten Kontaktstiftdicke entsprechenden Stärke. Aus diesem wird jeweils ein Rohling unter gleichzeitiger Bildung des Langlochs ausgestanzt; anschließend wird bei diesem Rohling dann die Schulter in einem Abdrehvorgang gebildet. Beide Herstellungswege sind relativ aufwendig und kostspielig.In a known contact pin contact spring socket assembly of this type according to an earlier application according to DE-A-39 15 644.3 (this document falls under Art. 54 (3) EPC), the contact pin is as with the carrier part that serves to limit the insertion path Has shoulder, one-piece component formed. This is first produced as a turned part, which comprises the shoulder and a contact pin section protruding therefrom, from which the elongated hole is punched out after the material that is superfluous on both sides has been milled and thus converted into a flat shape in a subsequent punching process. Instead, it is also possible to start from a contact sheet metal strip material with two strip regions of different thickness, namely a region with a thickness corresponding to the diameter of the shoulder and a region with a thickness corresponding to the desired contact pin thickness. A blank is punched out of each of these, simultaneously forming the elongated hole; the shoulder is then formed in a blanking process for this blank. Both manufacturing methods are relatively complex and expensive.
Es hat sich nun gezeigt, daß derartige Kontaktstift-Kontaktfederbuchsen-Baueinheiten auf wesentlich einfachere Weise als bisher in einwandfreier Qualität herstellbar sind, wenn der Kontaktstift erfindungsgemäß als von dem Trägerteil, das die der Begrenzung des Einsteckweges dienende Schulter aufweist unabhängiges Stanzteil ausgebildet und mit der Schulter über ein Klemmverbindungselement verbindbar ist. Zweckmäßigerweise ist das Trägerteil dabei mit einer auf der der Kontaktfederbuchse abgewandten Seite offenen Klemmbohrung versehen, in die der Kontaktstift mit seinem rückwärtigen Stiftende unter Herstellung einer Klemmverbindung einführbar ist.It has now been shown that such contact pin contact spring socket assemblies can be produced in a much simpler way than before in perfect quality if the contact pin is designed according to the invention as a stamped part which is independent of the carrier part which has the shoulder serving to limit the insertion path and can be connected to the shoulder via a clamping connection element. The carrier part is expediently provided with a clamping bore which is open on the side facing away from the contact spring bushing and into which the contact pin with its rear pin end can be inserted to produce a clamp connection.
Eine besonders einfache Ausführung ergibt sich, wenn das rückwärtige Stiftende des Kontaktstifts einen rechteckigen, vorzugsweise quadratischen Querschnitt besitzt und der Abstand der diametral einander gegenüberliegenden Stiftkanten auf den Durchmesser der Klemmbohrung abgestimmt ist.A particularly simple design results if the rear pin end of the contact pin has a rectangular, preferably square cross-section and the distance between the diametrically opposite pin edges is matched to the diameter of the clamping bore.
Eine qualitativ bessere Verbindung infolge elastischer Stiftverformung während des Einsteckvorgangs ergibt sich, wenn zwei einander gegenüberliegende Seiten des Stiftendes mit einer zur Stiftachse hin gerichteten, etwa achsparallelen Einwölbung versehen sind. Auf diese Weise können sich die äußeren Kantenbereiche beim Einsteckvorgang jeweils zur Krümmungsachse der Wölbung hin elastisch verformen.A qualitatively better connection as a result of elastic pin deformation during the insertion process is obtained if two opposite sides of the pin end are provided with an approximately axially parallel curvature directed towards the pin axis. In this way, the outer edge regions can each deform elastically towards the axis of curvature of the curvature during the insertion process.
Als in fertigungstechnischer Hinsicht und auch im Hinblick auf die Qualität der Verbindung besonders vorteilhaft hat es sich erwiesen, wenn das Stiftende analog zum Kontaktstift zwei etwa parallele, ein durch Ausstanzen gebildetes Rastlangloch begrenzende, aufeinanderzu federnde, in die Rastbohrung einführbare Rastschenkel aufweist.It has proven to be particularly advantageous in terms of production technology and also with regard to the quality of the connection if the pin end has two approximately parallel, resilient, resilient locking legs which can be inserted into the locking hole and which are analogous to the contact pin and delimit a punched slot.

Die Fig. 1 und 5 zeigen eine Kontaktbuchsen-Kontaktstift-Baueinheit 1 mit einer Kontaktfederbuchse 2 für die sichere Stromübertragung zu bzw. von einem in sie eingeführten, in der Zeichnung nicht dargestellten Steckerstift zu einem mit der Buchse mechanisch und elastisch verbundenen Kontaktstift 3. Für die Festlegung von Kontaktstift-Kontaktbuchsen-Baueinheiten 1 in Öffnungen einer nicht näher veranschaulichten elektrischen Leiterplatte ist der dem Steckerstifteinführungsende abgewandte, flach ausgebildete Kontaktstift 3 mit zwei etwa parallelen, ein durch Ausstanzen gebildetes Langloch 4 begrenzenden, aufeinander zu federnden Schenkeln 5 versehen. Diese Schenkel 5 laufen in ein Stiftende 6 aus, das in eine zentrale Klemmbohrung 7 in einem Trägerteil 8 mit einer der Begrenzung des Einsteckweges dienenden Schulter 8 der Kontaktfederbuchse 2 vorgesehen ist. Wie ersichtlich, liegen bei dem veranschaulichten Ausführungsbeispiel die ins Buchseninnere eingeführten Kontaktfedern 9 mit ihrem hinteren Ende an einem zylindrischen Ringansatz 10 an, der von der Schulter vorsteht und an seinem Fuß eine Ringnut 11 aufweist. In diese Ringnut 11 greift der umgebördelte Rand des in Form einer dünnwandig verformbaren Hülse ausgebildeten Buchsenkörpers 12 der Kontaktfederbuchse 2 ein. Dabei preßt der Rand unter stirnseitiger Anlage an der Schulter die zwischen ihm und dem Ringansatz 10 befindlichen Kontaktfedern 9 fest an.1 and 5 show a contact socket contact pin assembly 1 with a
Innerhalb des durch eine Umbördelung gebildeten Funkenschutzrandes mit einer zentralen Stifteinführöffnung 13 liegt an der Umbördelung ein Ringkörper 14 an, dessen Innendurchmesser etwas kleiner als die im Buchsenkörper 12 vorgesehene Stifteinführöffnung 13 gewählt ist. Die am Innenumfang verteilten Kontaktfedern 9, die im Bereich der Schulter fixiert sind, sind mit ihren freien Enden frei beweglich in einem zwischen dem Buchsenkörper 12 und dem Ringkörper 14 begrenzten Ringspalt 15 geführt.Within the spark protection rim formed by a flange with a central pin insertion opening 13, an
Die in Fig. 5 veranschaulichte radial nach innen gerichtete Wölbung der Kontaktfedern 9 ist dadurch erzielt, daß der Buchsenkörper 12 von außen her an zwei in Bezug auf den Ringkörper 14 bzw. den Ringansatz 10 axial versetzten Stellen mit Abstand voneinander jeweils mit einer radial nach innen ragenden Ringwulst 16 bzw. 17 versehen ist, die an den Kontaktfedern 9 anliegt und sie radial nach innen elastisch verformt. Der Buchsenkörper 12 ist im Bereich jeder Ringwulst 16 bzw. 17 mit einem Innendurchmesser versehen, der kleiner ist als der Außendurchmesser des die freien Enden der Kontaktfedern 6 abstützenden Ringkörpers 14, vermehrt um den doppelten Durchmesser der Kontaktfedern 9.The radially inward curvature of the
Bei der in Fig. 1 vereinfacht dargestellten Kontaktbuchsen-Kontaktstift-Baueinheit 1 ist gegenüber der mehr ins einzelne gehend veranschaulichten Ausführung nach Fig. 5 eine zusätzliche radial Einprägung 18 vorgesehen, um die nicht gezeigten Kontaktfedern innerhalb der Kontaktfederbuchse 2 fest an den ebenfalls nicht dargestellten Ringansatz 10 anzupressen.In the case of the contact socket / contact pin assembly 1, which is shown in simplified form in FIG. 1, the embodiment according to FIG. 5 is illustrated in more detail an additional
Fig. 2 veranschaulicht die einfachste Form der Bildung des rückwärtigen Stiftendes 6 des Kontaktstifts 3. Hier besitzt das Stiftende 6 nämlich einen rechteckigen, vorzugsweise quadratischen Querschnitt, und der Abstand der diametral einander gegenüberliegenden Stiftkanten ist auf den Durchmesser der Klemmbohrung 7 abgestimmt. Durch leichte Überdimensionierung des Stiftkantendiagonalabstands greifen die Stiftkanten beim Verbinden des Kontaktstifts 3 über das Stiftende 6 in die Wandung der Klemmbohrung 7 der Kontaktfederbuchse 2. Auf diese Weise ist ein fester Halt und auch ein einwandfreier Kontakt gewährleistet.Fig. 2 illustrates the simplest form of the formation of the
Die Ausführung gemäß Fig. 3 zeigt eine demgegenüber verbesserte Querschnittsform des Stiftendes 6. Wie in dieser Figur angedeutet, sind zwei einander gegenüberliegende Seiten des Stiftendes 6 mit einer zur Stiftachse hin gerichteten, etwa achsparallelen Einwölbung 19 versehen. Dadurch sind die äußeren Kantenbereiche des Stiftendes 6 beim Einsteckvorgang jeweils zur Krümmungsachse der Wölbung 19 hin elastisch verformbar.The embodiment according to FIG. 3 shows an improved cross-sectional shape of the
Eine qualitativ bessere Verbindung des Kontaktstifts 3 mit der Kontaktbuchse 2 infolge elastischer Stiftverformung während des Einsteckvorgangs ist bei der Ausführung nach den Fig. 4 und 5 sichergestellt. Wie ersichtlich, ist das Stiftende 6 analog zum eigentlichen Kontaktstift 3 mit einer Ausstanzung versehen, durch die zwei ein Klemmlangloch 20 begrenzende Klemmschenkel 21 gebildet sind, die beim Einführen in die Klemmbohrung 7 aufeinander zu federn.A better quality connection of the
