Description

  • Die Erfindung bezieht sich auf eine Messerleiste nach dem Oberbegriff des Patentanspruchs, also auf Bauteile in der industriellen Elektronik, bei deren Herstellung Lötarbeiten mehr und mehr durch die weitaus vorteilhaftere Einpreßtechnik ersetzt werden. The invention relates to a blade connector according to the preamble of the patent claim, ie components in the electronics industry, in the production soldering are more and more replaced by the much more favorable press-fit technology.
  • Diese Technik ist beispielsweise bereits aus der US-A- 4 125 935 bekannt, wobei bei einer speziellen dort gezeigten Ausführung auf eine Leiterplatte hin abgebogene, aus einem Isoliergehäuse ragende Kontaktstifte in dem einteiligen Gehäuse befestigt sind. This technique is known for example from US-A-4,125,935 already, whereby a printed circuit board bent back, projecting from an insulating contact pins are mounted in the one-piece housing in a particular embodiment shown there. Das Einpressen der Kontaktstifte in die Leiterplatte erfolgt dabei durch ein spezielles Werkzeug, das auf der Obeseite des Gehäuses und auf den Oberseiten der aus dem Gehäuse ragenden Kontaktstifte aufliegt. The pressing of the contact pins in the printed circuit board is effected by a special tool, which rests on the Obeseite of the housing and on the tops of the projecting from the housing contact pins. Eine solche Ausgestaltung führt jedoch sehr häufig zu Fehlsteckungen bzw. Beschädigungen durch Verbiegen der Kontaktstifte bei der Montage, weil hier das Einpressen durch Druck auf die Oberseiten der Abwinkelungen erfolgt, also weit entfernt von der eigentlichen EinpreßsteIle an der Leiterplatte und die langen, relativ dünnen Kontaktstifte somit im Zwischenbereich überhaupt keine seitliche Führung erhalten. However, such a design very often leads to improper connections or damage from bending the pins during assembly, because here is done the pressing by pressing the tops of the bends, so far removed from the actual EinpreßsteIle to the circuit board and the long, relatively thin pins therefore receive no lateral guidance in the intermediate region.
  • Eine weiterhin aus der US-A- 4 045 868 bekannte Ausführung zeigt bei einer Federleiste ua ein abnehmbares Gehäuseteil, das zugleich als Isoliergehäuseteil und Einpreßwerkzeug dienen kann. A further known from US-A- 4,045,868 shows known embodiment with a spring strip, inter alia, a removable housing part, which may also serve as insulation case member and press-in tool. Abgesehen davon, daß es sich hier um keine auf die Leiterplatte hin abgewinkelten Kontaktstifte handelt, wird auch bei dieser Ausführung der Einpreßdruck auf die Einpreßzone der Stiftenden von der Stiftoberseite her aufgebracht, ohne daß eine ausreichende seitliche Führung der Stifte bis zur Einpreßzone hin vorgesehen ist. Besides the fact that this is not a to the circuit board angled towards the contact pins, the injection pressure is applied to the press-in zone of the pin ends of the pin upper side, without an adequate lateral guidance of the pins is provided to the press-in zone towards also in this embodiment. Fehlsteckungen und Beschädigungen bei der Montage sind auch hier die unausbleibliche Folge. Improper connections and damage during installation are the inevitable result here.
  • Gleiches oder ähnliches gilt auch für die weiterhin noch bekannten Ausführungen nach den US-A- 4 035 047, 4 202 593, 3 769 679 sowie die DE-C- 31 33 155. Like or similar also applies to the further yet known embodiments according to US-A- 4,035,047, 4,202,593, 3,769,679 and DE-C 31 33 155th
  • Aufgabe der vorliegenden Erfindung ist es daher, an Steckverbindern der eingangs beschriebenen Art geeignete bauliche Maßnahmen vorzusehen, um auch hierdie moderne sowie technisch fortschrittliche Einpreßtechnik einfach und erfolgreich anwenden zu können, ohne daß die zuvor beschriebenen Mängel bei der Montage auftreten können. Object of the present invention is therefore to provide appropriate design of connectors of the type described above, in order to apply also hierdie modern and technically advanced press-in easily and successfully without the deficiencies described above in the assembly may occur.
  • Gelöst wird diese Aufgabe dabei durch die im einzigen Patentanspruch definierte Messerleiste, deren besonderer Vorteil in dem als ständige Führung dienenden Formschluß zwischen den beidseits schrägen bzw. geneigt verlaufenden Auflagepartien der Stege sowie Oberseiten der schulterartigen Anschläge zu sehen ist, denn nur dadurch wird die aufgabengemäße, exakte Zentrierung sowie Führung der freien Enden der äußerst empfindlichen, dünnen Kontaktpfosten auf die Lochmitten hin während des gesamten Steck- und Einpreßvorgangs erzielt und Fehlsteckungen durch verbogene Pfosten und damit Ausschuß sicher vermieden. This object is achieved here by the device defined in the single claim male connector, which benefits in which serves as a permanent guide form circuit between the both sides of the oblique, or sloping resting portions of the webs and upper sides of the shoulder-like attacks can be seen, because only by the object is proper, exact centering and guiding the free ends of the extremely sensitive, thin contact posts made on the hole centers out throughout the plug-in and pressing-and improper connections reliably avoided by bent posts and thus Committee.
  • Ein Ausführungsbeispiel der Erfindung ist anhand der Zeichnungen im folgenden noch näher beschrieben. An embodiment of the invention is described in more detail with reference to the drawings.
  • Es zeigen: Show it:
    Figure imgb0001
  • Aus der perspektivischen Darstellung gemäß Figur 1 ist zunächst einmal der generell bekannte Grundaufbau einer Messerleiste zu erkennen, nämlich, daß die frei aus dem Isoliergehäuse 1 der Leiste 2 herausragenden Anschlußenden 3 der einzelnen Kontaktstifte 4, für die Anwendung der Einpreßtechnik in an sich bekannter Weise einen zum Einpressen in durchkontaktierten Bohrungen 5 von Leiterplatten 6 geeigneten, entsprechend profilierten, Einpreßabschnitt 7 aufweisen, wobei gemäß Fig. 2 und 3 noch zu ersehen ist, daß zur Begrenzung der Einpreßtiefe t die jeweiligen Einpreßabschnitte 7 nach oben, also zum Pfostenschaft 4 hin, mit einem in seinen Abmessungen b gegenüber dem Pfostenquerschnitt q vergrößerten, schulterartigen Anschlag 8 versehen sind. From the perspective illustration according to Figure 1 of generally known basic design of a blade strip is first of all be seen, namely that the free from the insulating housing 1, the bar 2 projecting terminal ends 3 of each of the contact pins 4, for the application of press-fit technology in a known manner a have to be pressed into through holes 5 of circuit boards 6 suitable, appropriately profiled, press-in portion 7, wherein according to Fig. 2 and 3 can still be seen that for limiting the depth of pressing the respective press-in portions 7 t upwards, so to the pole shaft 4 out with an enlarged in size b relative to the post cross-section q, shoulder-like stopper are provided. 8
  • Die Einpreßenden 7 der in einer oder mehreren parallelen Reihen liegenden Kontaktstifte 4 sind rechtwinklig auf eine gemeinsame Ebene hin abgebogen und als Einpreßwerkzeug sowie Isolierabdeckung zugleich dient ein weiteres Gehäuse 9, welches mit taschen- oder kammartigen Aussparungen 10 versehen ist, deren Rückenteile 10a oberhalb der Abwinklungen 4a der Einpreßpfosten 4 verlaufen und deren Stege 11 sich einerseits bis zwischen die schulterartigen Anschläge 8 jeweils benachbarter Pfosten 4 erstrecken und andererseits mit einer zu den Anschlägen 8 korrespondierenden Formgebung 1a ihrer freien Enden 11b auf der Oberseite 8a derselben aufliegen. The Einpreßenden 7 of the contact pins 4 lie in one or more parallel rows are bent at right angles to a common plane to and as a press-in tool as well as insulating cover also serves a further housing 9, which is provided with the pocket or comb-like recesses 10, the ridge portions 10a above the bends 4a extend the press-in pins 4 and their webs 11 extend between on the one hand to the shoulder-like stops 8 of adjacent posts 4 and on the other hand, with a corresponding to the stops 8 1a shaping of the free ends 11b on the upper side 8a rest thereof.
  • Durch diese Ausbildung erfolgt zum einen eine gute Kraftübertragung während des Einpreßvorgangs vom Aufsatzgehäuse 9 aus über die Schultern 8a unmittelbar auf den Bereich der Einpreßenden 7 und zum anderen ist gewährleistet, daß durch die im Endzustand zwischen jeweils zwei benachbarten Anschlägen bzw. Schultern 8 liegenden Gehäuseteilen 11, 11a, 11b eine einwandfreie elektrische Isolation gegeneinander gegeben ist. By this design a good force transmission is effected on the one hand during the pressing process from the tower housing 9 over the shoulders 8a directly to the area of ​​Einpreßenden 7 and on the other hand it is ensured that, by lying in the final state in each case between two adjacent stops or shoulders 8 housing parts 11 , 11a, 11b, a proper electrical insulation is placed against each other.
