Derartige Steckverbinder sind insbesondere im Zusammenhang mit dem von mehreren Computerherstellern angestrebten stan¬ dardisierten USB (Universal Serial Bus) -Konzept bekannt ge¬ worden und von Interesse. Bei diesem neuen Bus-System geht es grundsätzlich darum, die Anschlüsse von Peripheriegeräten an einen PC nicht mehr wie bisher über einzelne, parallele An- Schlüsse mit getrennten und oft unterschiedlichen Steckver¬ bindersystemen vorzunehmen, sondern die Peripheriegeräte im wesentlichen seriell an eine gemeinsame Bus-Leitung anzu¬ schließen, die über eine standardisierte Steckbuchse am Ge¬ häuse des PC unmittelbar mit einer Leiterplatte (motherboard) des PC verbunden ist. Das Steckgesicht der Leiterplatten- Steckbuchse (receptacle) gemäß dem oben zitierten Oberbegriff des Patentanspruches 1 ist im wesentlichen bereits durch eine Spezifikation festgelegt und weist vier in einer Ebene neben- einander liegende, streifenförmige Kontaktfedern auf, die beim Stecken des Bussteckers (plug) mit den in diesen ange¬ ordneten vier nebeneinander liegenden Kontaktschienen bzw. - bahnen zusammenwirken und den elektrischen Kontakt herstel- len. Die Kontaktfedern sind im Buchsenstecker in einem Isola¬ tionskörper, der im wesentlichen als Kunststoffzunge mit rechteckigem Querschnitt ausgebildet ist, angeordnet und sind in ihrem hinteren Bereich zu nach unten wegstehenden An- schlußbeinchen abgewinkelt, die in Kontaktlöcher der Leiter- platte einsteckbar sind. Stecker und Gegenstecker sind übli¬ cherweise mit einem metallischen Schirmgehäuse versehen. Im Decken- und Bodenbereich dieser Schirmbleche sind jeweils zwei Rasthaken vorgesehen, die in Aussparungen am Schirmge¬ häuse des passenden Gegensteckers eingreifen und die Halte- kräfte beim Ausziehen des plugs und den Erdungskontakt reali¬ sieren.Such connectors have become known and are of interest, in particular, in connection with the standardized USB (Universal Serial Bus) concept sought by several computer manufacturers. With this new bus system it is basically a matter of no longer connecting peripheral devices to a PC via individual, parallel connections with separate and often different connector systems, as before, but essentially connecting the peripheral devices serially to a common bus system. To connect line, which is connected directly to a PC (motherboard) of the PC via a standardized socket on the housing of the PC. The mating face of the circuit board socket (receptacle) according to the preamble of claim 1 cited above is essentially already defined by a specification and has four in one plane. Strip-shaped contact springs lying one on top of the other, which, when the bus plug is plugged in, interact with the four contact rails or tracks arranged next to one another and produce the electrical contact. The contact springs are arranged in the socket plug in an insulation body, which is essentially designed as a plastic tongue with a rectangular cross-section, and are angled in their rear region towards connecting legs which protrude downward and can be inserted into contact holes in the printed circuit board. The connector and mating connector are usually provided with a metallic shield housing. Two latching hooks are provided in the ceiling and floor area of these shield plates, which engage in recesses on the shield housing of the matching mating connector and which realize the holding forces when the plug is pulled out and the grounding contact.
In Figur 4 ist dargestellt, wie bei einem Steckverbinderpär¬ chen gemäß der Spezifikation der obere Rasthaken 7 in der Aussparung 11 des Schirmgehäuses 13 des Gegensteckers 14 pla¬ ziert ist. Die Höhe der Kraftwirkung hängt neben der Feder- steifigkeit vor allem davon ab, wie tief der Rasthaken 7 in die Aussparung 11 einschnappt. Je größer die Oberdeckung ist, desto stärker wird die Feder beim Ausziehen des Gegensteckers 14 gespannt. Beim bekannten Stecker ist die Oberdeckung durch die Blechdicke des Gegensteckers begrenzt, da der Rasthaken 7 dann auf der Kunststoffzunge 1 des Buchsensteckers aufliegt.FIG. 4 shows how, in the case of a connector pair according to the specification, the upper latching hook 7 is placed in the recess 11 in the shield housing 13 of the mating connector 14. In addition to the spring stiffness, the amount of the force effect depends above all on how deep the latching hook 7 snaps into the recess 11. The greater the cover, the more the spring is tensioned when the mating connector 14 is pulled out. In the known connector, the upper cover is limited by the sheet thickness of the mating connector, since the latching hook 7 then rests on the plastic tongue 1 of the socket connector.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Buchsensteckverbinder der eingangs genannten Art zu schaffen, bei dem die Ausziehkraft erhöht ist.The present invention has for its object to provide a socket connector of the type mentioned, in which the pull-out force is increased.
Bei einem Steckverbinder der eingangs genannten Art wird die¬ se Aufgabe dadurch gelöst, daß die Oberseite der Kunststoff- zunge zwei Vertiefungen aufweist, in die jeweils einer der beiden oberen Rasthaken von oben her eintaucht. Die Erfindung wird nachfolgend anhand eines Ausführungsbei- spieles im Zusammenhang mit Figuren näher erläutert.In the case of a plug connector of the type mentioned at the outset, this object is achieved in that the upper side of the plastic tongue has two depressions into which one of the two upper latching hooks is inserted from above. The invention is explained in more detail below on the basis of an exemplary embodiment in connection with figures.
Es zeigen Figur 1 eine perspektivische Ansicht eines Buchsensteckver¬ binders gemäß der Erfindung zusammen mit einem noch nicht gesteckten Gegenstecker, Figur 2 das Steckverbinderpärchen gemäß Figur 1 in einer ge¬ schnittenen Seitenansicht, Figur 3 eine schematische geschnittene Seitenansicht desFIG. 1 shows a perspective view of a socket connector according to the invention together with a mating connector which has not yet been inserted, FIG. 2 shows the connector pair according to FIG. 1 in a sectional side view, FIG. 3 shows a schematic sectional side view of the
Steckverbinderpärchens gemäß den Figuren 1 und 2, je¬ doch im zusammengesteckten Zustand, Figur 4 in gleicher Darstellung wie Figur 3 ein Steckverbin¬ derpärchen gemäß dem Stand der Technik.Connector pairs according to FIGS. 1 and 2, but in the mated condition, FIG. 4 in the same representation as FIG. 3 shows a connector pair according to the prior art.
In den Figuren 1 bis 3 ist jeweils einerseits der Kabelstek- ker mit seinem Schirmgehäuse 13 und den Aussparungen 11, 12 und andererseits der Buchsenstecker mit seinem typischen Steckgesicht erkennbar. In der Decke 4 und dem Boden 5 des Schirmbleches 2 sind paarweise angeordnete Rasthaken 7, 8 bzw. 9, 10 erkennbar. Erkennbar ist außerdem die integrierte Kunststoffzunge 1, die einen Teil des Isolationskörpers bil¬ det. In der Oberseite 3 der Kunststoffzunge 1 sind zwei Ver¬ tiefungen 16 vorgesehen, in die die oberen Rasthaken 7, 8 von oben her eintauchen. Besonders bei der zusammengestecktenFIGS. 1 to 3 each show the cable connector with its shield housing 13 and the cutouts 11, 12 on the one hand, and the socket connector with its typical mating face on the other. In the ceiling 4 and the bottom 5 of the shield plate 2, locking hooks 7, 8 and 9, 10 arranged in pairs can be seen. The integrated plastic tongue 1, which forms part of the insulation body, can also be seen. In the top 3 of the plastic tongue 1, two recesses 16 are provided, into which the upper latching hooks 7, 8 dip from above. Especially when put together
Steckerpaarung gemäß Figur 3 ist die starke Überdeckung von Rasthaken 7, 8 und Schirmgehäuse 13 des Kabelsteckers, durch die die Ausziehkraft wesentlich erhöht wird, zu erkennen. In der dargestellten Position hinterschnappen die Rasthaken 7 sicher und plaziert. Trotz Vertiefungen 16 auf der Oberseite 3 und Ausnehmungen für die Kontaktbahnen 17 auf der Untersei¬ te 6 der Kunststoffzunge 1 weist diese noch eine genügende Stabilität auf. Selbstverständlich können die erfindungsgemä¬ ßen Vertiefungen 16 vorteilhaft auch an der Unterseite der komplementären Kunststoffzunge des Gegensteckers 14 vorgese¬ hen werden. The pair of plugs according to FIG. 3 shows the strong overlap of locking hooks 7, 8 and shield housing 13 of the cable plug, by means of which the pull-out force is significantly increased. In the position shown, the snap hooks 7 snap securely and in place. Despite recesses 16 on the top 3 and recesses for the contact tracks 17 on the bottom 6 of the plastic tongue 1, this still has sufficient stability. Of course, the depressions 16 according to the invention can advantageously also be provided on the underside of the complementary plastic tongue of the mating connector 14.
