Abstract

An electrical plug connector includes a socket provided for inserting an electrically conductive contact pin and formed by two parallel contact plates which are spaced a distance apart and extend from a base member counter to the plugging direction; the plug connector also includes at least one latching connection which maintains the contact plates in a pretensioned state with respect to one another and twisted in relation to the base member when the plug connector is in its initial state ready for insertion and which is releasable by inserting the contact pin.

Description

Stand der TechnikState of the art

Die Erfindung betrifft einen elektrischen Steckverbinder mit einer zum Einführen eines elektrisch leitenden Kontaktpins vorgesehenen Steckaufnahme.The invention relates to an electrical connector with a plug-in receptacle provided for insertion of an electrically conductive contact pin.

Derzeit sind im Automotivbereich Kontaktsysteme bekannt, bei denen Kontaktlamellen in einem vorgespannten Zustand für die Steckung auf den Kontaktpin bereitstehen. Diese Vorspannung wird dadurch erreicht, dass die Kontaktlamellen bewusst aus einem zunächst überbogenen Zustand zurückgebogen werden und in dieser neuen Lage durch starre Widerlager an einer Stahlüberfeder abgestützt werden. Durch die Vorspannung der Kontaktlamellen soll ein großes Kontaktgap eingestellt werden, ohne die im gesteckten Zustand wirksamen Kontaktnormalkräfte zu senken, die durch den Vorverbiegungszustand der Kontaktlamellen im unbelasteten Zustand definiert werden. Der Vorteil eines auf diese Weise eingestellten großen Kontaktgaps liegt darin, dass die hohe Reibkraft zu Beginn des Steckvorgangs (Aufschnäbel-Peak im Steckkraft-Weg-Diagramm) erheblich reduziert wird, da die Kontaktlamellen und der Kontaktpin erst unmittelbar vor dem parallelen Bereich des Kontaktpins aufeinandertreffen, also in einem Bereich, in dem die Gleitwinkel - bezogen auf die Reibkräfte - günstiger sind.At present, contact systems are known in the automotive sector, in which contact blades are available in a biased state for the connection to the contact pin. This bias is achieved in that the contact blades are deliberately bent back from an initially over-arched state and are supported in this new position by rigid abutment on a Stahlüberfeder. By the bias of the contact blades, a large Kontaktgap to be set without lowering the effective in the mated state contact normal forces, which are defined by the Vorverbiegungszustand the contact blades in the unloaded state. The advantage of being on This set large Kontaktgaps is that the high frictional force at the beginning of the plug-in process (Aufschnäbel peak in the insertion force-way diagram) is significantly reduced because the contact blades and the contact pin meet only immediately in front of the parallel portion of the contact pin, so in one Range in which the slip angle - related to the friction forces - are cheaper.

Weiterhin wird durch ein großes Kontaktgap die Wahrscheinlichkeit einer Hintersteckung der Kontaktlamellen reduziert. Bei bekannten Kontaktsystemen mit vorgespannten Kontaktlamellen handelt es sich bei den Widerlagern für die Vorspannung um starre Elemente der Stahlüberfeder, die die Federbewegung der Kontaktlamellen auch im gesteckten Zustand einseitig begrenzen. Aufgrund der engen Toleranzen solcher Federsysteme besteht die Gefahr, dass die Kontaktkraft nicht vollständig erreicht wird bzw. dass der Kontaktpin nur einseitig kontaktiert wird. Elektrische Steckverbinder für schüttelfeste Steckverbindungen sind etwa aus der DE 200 06 550 bekannt. Schiebbare elektrische Steckvorrichtungen sind auch aus der DE 195 11 225 bekannt.Furthermore, the probability of back-insertion of the contact blades is reduced by a large contact gap. In known contact systems with prestressed contact blades, the abutments for the prestressing are rigid elements of the steel coil spring, which limit the spring movement of the contact blades in the inserted state on one side. Due to the tight tolerances of such spring systems there is a risk that the contact force is not fully achieved or that the contact pin is contacted only on one side. Electrical connectors for shake resistant connectors are approximately from the DE 200 06 550 known. Slidable electrical plug devices are also from the DE 195 11 225 known.

US-A-4 887 980 offenbart einen Steckverbinder nach dem Oberbegriff des Anspruchs 1. U.S.-A-4,887,980 discloses a connector according to the preamble of claim 1.

Vorteile der ErfindungAdvantages of the invention

Der erfindungsgemäße elektrische Steckverbinder mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat den Vorteil, dass die Kontaktlamellen im aufgesteckten Zustand über ihren gesamten Federbereich ohne Beeinflussung durch Spreizelemente arbeiten können. Durch die sehr genaue Art der Vorspannungseinstellung wird der Aufschnäbel-Peak während des Steckvorganges bis auf das Niveau der Gleitreibungskräfte im Plateaubereich des Steckkraft-Weg-Verlaufs reduziert. Er lässt sich ferner in Kontaktsysteme implementieren, deren vorderer Kontaktierbereich schwingungstechnisch von einem Crimpbereich und einer Stahlüberfeder entkoppelt ist, da Wechselwirkungen mit den umgebenden Elementen des Kontakts bei diesem System nicht notwendig sind. Auch lässt sich ein solcher Steckverbinder in sehr engen Toleranzen fertigen, da es sich ausschließlich um Stanz-Biegeprozesse handelt und die Präzision von Stanzprozessen an dieser Stelle das Gap-Maß definiert.The electrical connector according to the invention with the characterizing features of claim 1 has the advantage that the contact blades can operate in the plugged state over their entire spring range without interference from spreading. Due to the very precise nature of the bias setting, the peaking peak is reduced during the mating process to the level of sliding friction forces in the plateau region of the insertion force path. It can also be implemented in contact systems whose front contact area is vibration-decoupled from a crimp area and a steel over-spring, since interactions with the surrounding elements of the contact are not necessary in this system. Also, such a connector can be manufactured in very tight tolerances, since it is all about stamping and bending processes and the precision of punching processes at this point defines the gap dimension.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Der in Fig. 1 in seinem Ausgangszustand gezeigte elektrische Steckverbinder 1 weist einen rahmenförmigen Grundkörper 2 sowie eine Steckaufnahme 3 auf, in die ein flacher Kontaktpin 4 ( Fig. 2 ) in Steckrichtung 5 einführbar ist. Die Steckaufnahme 3 ist durch zwei parallele zungenförmige Kontaktlamellen 6, 7 gebildet, zwischen denen der Kontaktpin 4 in den Steckverbinder 1 eingeführt wird. Die beiden Kontaktlamellen 6, 7 sind an ihrem einen Ende integral mit dem Grundkörper 3 verbunden, nämlich die in Fig. 1 obere Kontaktlamelle 6 am oberen Rahmenschenkel 2a und die untere Kontaktlamelle 7 am unteren Rahmenschenkel 2b des Grundkörpers 3, während sich die freien Enden 6a, 7a der Kontaktlamellen 6, 7 entgegen der Steckrichtung 5 erstrecken.The in Fig. 1 shown in its initial state electrical connector 1 has a frame-shaped base body 2 and a plug-in receptacle 3 , in which a flat contact pin 4 ( FIG. Fig. 2 ) in the insertion direction 5 is inserted. The plug-in receptacle 3 is formed by two parallel tongue-shaped contact blades 6, 7 , between which the contact pin 4 is inserted into the connector 1. The two contact blades 6, 7 are integrally connected at one end to the main body 3, namely the in Fig. 1 upper contact blade 6 on the upper frame leg 2a and the lower contact blade 7 on the lower frame member 2b of the base body 3, while the free ends 6a, 7a of the contact blades 6, 7 extend counter to the insertion direction 5.

Die obere Kontaktlamelle 6 weist auf ihrer einen, in Fig. 2 rechten Seite eine seitlich vorstehende Rastlasche 8, die aus der Lamellenebene um 90° in Richtung auf die untere Kontaktlamelle 7 abgewinkelt ist, und auf ihrer anderen, linken Seite eine Stützlasche 9 auf. Analog weist die untere Kontaktlamelle 7 auf ihrer linken Seite eine seitlich vorstehende Rastlasche 10, die aus der Lamellenebene um 90° in Richtung auf die obere Kontaktlamelle 6 abgewinkelt ist, und auf ihrer rechten Seite eine Stützlasche 11 auf. Der Steckverbinder 1 ist vorzugsweise ein Stanzteil aus elektrisch leitendem Material, wie z.B. Eisen, Kupfer, Messing oder deren Legierungen.The upper contact blade 6 has on its one, in Fig. 2 right side a laterally projecting latching tab 8, which is angled from the slat plane by 90 ° in the direction of the lower contact blade 7, and on its other, left side a support tab 9 . Analogously, the lower contact blade 7 on its left side a laterally projecting locking tab 10, which is angled away from the lamellar plane by 90 ° in the direction of the upper contact blade 6, and on its right side a support tab 11 . The connector 1 is preferably a stamped part of electrically conductive material, such as iron, copper, brass or their alloys.

Im Ausgangszustand des Steckverbinders 1 sind einerseits, wie die Fign. 1 und 2 zeigen, die Rastlaschen 8, 10 jeweils auf den Stützlaschen 9, 11 abgestützt, und zwar mit Vorspannung, und andererseits sind die Kontaktlamellen 6, 7, wie die Fig. 2 zeigt, im Bereich der Laschen 8 bis 11 gegenüber ihren Rahmenschenkeln 2a, 2b schraubenartig im Uhrzeigersinn verdreht und somit entgegen dem Uhrzeigersinn in ihre zu den Rahmenschenkeln 2a, 2b parallele Lage vorgespannt. Die Rast- und Stützlaschen 8 bis 11 bilden auf beiden Seiten der Kontaktlamellen 6, 7 jeweils eine Rastung 12, durch die die Kontaktlamellen 6, 7 aufeinander zu und entgegen dem Uhrzeigersinn zum Grundkörper 3 vorgespannt sind. Zwischen den Stütz- und Rastlaschen 8 bis 11 und den freien Enden 6a, 7a weisen die Kontaktlamellen 6, 7 auf ihren einander zugewandten Innenseiten jeweils einen als erhabene hügelartige Kontaktkuppe ausgebildeten Kontaktpunkt 13, 14 auf, mit dem der Steckverbinder 1 den eingeführten Kontaktpin 4 kontaktiert. Im einführbereiten Ausgangszustand des Steckverbinders ist der Abstand der Kontaktlamellen 6, 7 größer als die Dicke des Kontaktpins 4.In the initial state of the connector 1 are on the one hand, as the FIGS. 1 and 2 show, the locking tabs 8, 10 each supported on the support tabs 9, 11, with bias, and on the other hand, the contact blades 6, 7, as the Fig. 2 shows, in the region of the tabs 8 to 11 with respect to their frame legs 2a, 2b helically twisted in a clockwise direction and thus biased counterclockwise in their relation to the frame legs 2a, 2b parallel position. The locking and support tabs 8 to 11 form on both sides of the contact blades 6, 7 each have a detent 12, through which the contact blades 6, 7 are biased toward each other and counterclockwise to the main body 3. Between the support and locking tabs 8 to 11 and the free ends 6a, 7a, the contact blades 6, 7 each have on their mutually facing inner sides as a raised hill-like Contact tip trained contact point 13, 14 , with which the connector 1 contacts the inserted contact pin 4. In the ready-initial state of the connector, the distance between the contact blades 6, 7 is greater than the thickness of the contact pin. 4

Die Fign. 2 bis 5 zeigen schematisch die zeitliche Abfolge beim Einführen des Kontaktpins 4 in die Steckaufnahme 3 des Steckverbinders 1, wobei in der unteren Hälfte schematisch jeweils die Interaktion des Kontaktpunktes 13 der unteren Kontaktlamelle 7 mit dem Kontaktpin 4 in einer schematischen Ansicht von oben dargestellt ist.The FIGS. 2 to 5 schematically show the time sequence during insertion of the contact pins 4 in the plug-in receptacle 3 of the connector 1, wherein in the lower half schematically each interaction of the contact point 13 of the lower contact blade 7 is shown with the contact pin 4 in a schematic view from above.

In der in Fig. 2 gezeigten aufnahmebereiten Ausgangsstellung des Steckverbinders 1 sind die Kontaktlamellen 6, 7 durch die beiden Rastungen 12 aufeinander zu und verdreht zum Grundkörper 3 vorgespannt gehalten. Der Querabstand zwischen beiden Rastlaschen 8, 10 ist mit a bezeichnet und ist kleiner als die Breite des Kontaktpins 4, dessen vorderer Steckbereich 4a verjüngt ist.In the in Fig. 2 shown receptive starting position of the connector 1, the contact blades 6, 7 held by the two notches 12 toward each other and twisted biased to the base body 3. The transverse distance between the two locking tabs 8, 10 is designated by a and is smaller than the width of the contact pin 4, the front plug-in portion 4a is tapered.

Fig. 3 zeigt den Steckverbinder 1 und den in die Steckaufnahme 3 eingeführten Kontaktpin 4, dessen vorderer Steckbereich 4a noch nicht auf die Rastlaschen 8, 10 des Steckverbinders 1 aufgelaufen ist. Der Kontaktpin 4 ist noch nicht in Kontakt mit den Kontaktpunkten 13, 14 der Kontaktlamellen 6, 7. Fig. 3 shows the connector 1 and introduced into the receptacle 3 contact pin 4, the front plug-in portion 4a has not yet accumulated on the locking tabs 8, 10 of the connector 1. The contact pin 4 is not in contact with the contact points 13, 14 of the contact blades 6, 7th

Fig. 4 zeigt den Steckverbinder 1 und den tiefer in die Steckaufnahme 3 eingeführten Kontaktpin 4, der mit seinem verjüngten vorderen Steckbereich 4a nunmehr zwischen die Rastlaschen 8, 10 des Steckverbinders 1 eingeschoben ist. Dadurch sind die Rastlaschen 8, 10 in Querrichtung auf ein Maß b gegeneinander aufgespreizt, liegen aber noch auf den Stützlaschen 9, 11 auf. Der Kontaktpin 4 ist noch nicht in Kontakt mit den Kontaktpunkten 13, 14 der Kontaktlamellen 6, 7. Fig. 4 shows the connector 1 and the deeper inserted into the receptacle 3 contact pin 4, which is now inserted with its tapered front plug portion 4a between the locking tabs 8, 10 of the connector 1. As a result, the locking tabs 8, 10 are spread in the transverse direction to a dimension b against each other, but are still on the support tabs 9, 11. The contact pin 4 is not in contact with the contact points 13, 14 of the contact blades 6, 7th

Sobald durch weiteres Einführen des Kontaktpins 4 die Stützlaschen 8, 10 in Querrichtung vollständig auf die Breite c des Kontaktpins 4 aufgespreizt sind, liegen die Rastlaschen 8, 10 nicht mehr auf den Stützlaschen 9, 11 auf. Die Rastungen 12 sind gelöst, so dass sich die beiden Kontaktlamellen 6, 7 aufgrund ihrer Vorspannungen sowohl aufeinander zu bewegen als auch entgegen dem Uhrzeigersinn in ihre zu den Rahmenschenkeln 2a, 2b parallele Lage zurückdrehen. Fig. 5 zeigt den Steckverbinder 1 in diesem Endzustand, in dem die Kontaktlamellen 6, 7 mit ihren Kontaktpunkten 13, 14 am Kontaktpin 4 anliegen und parallel zu den Rahmenschenkeln 2a, 2b ausgerichtet sind.As soon as further insertion of the contact pin 4, the support tabs 8, 10 are spread in the transverse direction completely to the width c of the contact pins 4, the locking tabs 8, 10 are no longer on the support tabs 9, 11. The detents 12 are released, so that the two contact blades 6, 7 both due to their biases to move toward each other and against the Turn back clockwise in its to the frame legs 2a, 2b parallel position. Fig. 5 shows the connector 1 in this final state in which the contact blades 6, 7 abut with their contact points 13, 14 on the contact pin 4 and are aligned parallel to the frame legs 2a, 2b.

Statt auf den seitlich vorstehende Stützlaschen 9, 11 können sich die Rastlaschen 8, 10 im aufnahmebereiten Ausgangszustand auch auf den Kontaktlamellen 6, 7 abstützen.Instead of the laterally projecting support tabs 9, 11, the locking tabs 8, 10 are supported in the receptive initial state on the contact blades 6, 7.
