Description

Die Erfindung betrifft eine Rundsteckhülse für einen runden Kontaktstift, die insbesondere für wasserdichte Steckkupplungen verwendbar ist.The invention relates to a circular socket for a round contact pin, which can be used in particular for waterproof plug-in couplings.

Eine wasserdichte Steckkupplung wird z.B. in der DE-OS 33 02 924 beschrieben. Wichtig ist, daß beim Einschieben der Steckkontakte in die dafür vorgesehenen Kammern die Dichtungselemente der Kammern durch z.B. scharfe Kanten an den Steckkontakten'nicht beschädigt werden.A waterproof plug-in coupling is e.g. described in DE-OS 33 02 924. It is important that when the plug contacts are inserted into the chambers provided for this purpose, the sealing elements of the chambers are replaced by e.g. sharp edges on the plug contacts are not damaged.

Auf dem Markt befindet sich eine einstückige Rundsteckhülse, die den oben genannten Anforderungen genügen soll.There is a one-piece circular receptacle on the market that should meet the above requirements.

Sie besteht in ihrer Längserstreckung aus mehreren Abschnitten, und zwar einem Leiteranschlußteil, einem sich daran anschließenden Lagerteil und einem am Lagerteil sitzenden Kontaktteil. Das Lagerteil ist als runde Hülse mit einer Stoßnaht ausgebildet. Ebenso ist das Kontaktteil als runde Hülse mit Stoßnaht ausgeführt, wobei im Bereich der Stecköffnung außen ein dicht auf die Kontakthülse geschlagener Kragen vorgesehen ist, der eine abgerundete Vorderkante schafft. Die abgerundete Vorderkante soll gewährleisten, daß beim Einschieben der Rundsteckhülse in eine Steckkupplungskammer die empfindlichen Dichtungslippen oder dgl. Dichtungselemente nicht beschädigt werden. Der Kragen soll außerdem die Kontakthülse trittfest machen und versteifen, damit beim Einschieben der Rundsteckhülse keine ungewollten Verbiegungen auftreten.In its longitudinal extension it consists of several sections, namely a conductor connection part, an adjoining bearing part and a contact part seated on the bearing part. The bearing part is designed as a round sleeve with a butt seam. The contact part is also designed as a round sleeve with butt seam, in the area of the plug-in opening a collar which is tightly fitted onto the contact sleeve is provided on the outside and creates a rounded front edge. The rounded front edge is intended to ensure that the sensitive sealing lips or similar sealing elements are not damaged when the round plug-in sleeve is inserted into a plug-in coupling chamber. The collar should also make the contact sleeve firm and stiffen so that no undesired bends occur when the round plug-in sleeve is inserted.

Diese bekannte Rundsteckhülse weist eine Reihe von Nachteilen auf. Die Kontakthülse ist sehr steif und erbringt keine genügend weiche Federwirkung für den Kontaktstift. Die Kontaktierung in der Kontakthülse ist relativ unbestimmt. Die Formgebung der Rundsteckhülse aus einer Platine erfordert einen relativ hohen Arbeitsaufwand, weil die Platine mit dem umgeschlagenen Kragen einen hohen Verformungswiderstand beim Einrollen verursacht. Da der Kragen außen aufliegt, ist sein Radius größer als der der Kontakthülse, so daß die Stoßkanten des Kragens auseinanderklaffen, während die der Kontakthülse aneinanderstoßen. Die auseinanderklaffenden relativ scharfen Kanten bergen die Gefahr der Verletzung von Dichtungselementen beim Einschieben der Rundsteckhülse in eine Steckkupplungskammer.This known circular connector has a number of disadvantages. The contact sleeve is very stiff and does not provide a sufficiently soft spring effect for the contact pin. The contact in the contact sleeve is relatively indefinite. The shaping of the circular receptacle from a circuit board requires a relatively high amount of work because the circuit board with the folded collar causes a high resistance to deformation when it is rolled up. Since the collar rests on the outside, its radius is larger than that of the contact sleeve, so that the abutting edges of the collar gap apart while those of the contact sleeve abut. The gaping, relatively sharp edges harbor the risk of damage to sealing elements when the circular plug-in sleeve is inserted into a plug-in coupling chamber.

Aufgabe der Erfindung ist, eine Rundsteckhülse der beschriebenen Art zu schaffen, die einen geringeren Arbeitsaufwand zu ihrer Herstellung erfordert, sehr gute Federkräfte und eine definierte Kontaktierung gewährleistet sowie keinerlei scharfe Kanten aufweist.The object of the invention is to provide a circular receptacle of the type described, which requires less work to produce, ensures very good spring forces and a defined contact, and has no sharp edges.

Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Anhand der Zeichnung wird die Erfindung beispielhaft näher erläutert, wobei Verallgemeinerungen des Beispiels und alle neuen Merkmale im Bereich der Kontakthülse zur Erfindung zählen, selbst wenn sie nicht unmittelbar beansprucht sind.

This object is solved by the features of the main claim. Advantageous developments of the invention are characterized in the subclaims. The invention is explained in more detail by way of example with the aid of the drawing, generalizations of the example and all new features in the area of the contact sleeve being part of the invention, even if they are not directly claimed.

Die Rundsteckhülse nach den Fig. 1 bis 4 besteht hauptsächlich aus dem Leiteranschlußteil 1, der eine Leiterdrahtkralle wie dargestellt oder ein anderes bekanntes Anschlußelement für z.B. die Klemmschneid- oder Löttechnik sein kann. Über einen im Querschnitt U-förmig gebogenen ' Übergangsbereich 2 schließt sich die runde Lagerhülse 3 an. Im Mantel der Lagerhülse 3 sind zweckmäßigerweise 1 Lappen 4a durch zur Längsachse 4 der Rundsteckhülse parallel ausgerichtete Einschnitte 5 eingebracht, die nach außen gewölbt sind und in an sich bekannter Weise einen Steckbegrenzungsrand ergeben.1 to 4 consists mainly of the conductor connection part 1, which has a conductor wire claw as shown or another known connection element for, for example, the clamping cutting or soldering technique can be. The round bearing sleeve 3 adjoins a transition region 2 which is bent in a U-shaped cross section. In the casing of the bearing sleeve 3, 1 tab 4a is expediently introduced through incisions 5 oriented parallel to the longitudinal axis 4 of the circular plug-in sleeve, which are curved outwards and produce a plug-limiting edge in a manner known per se.

Die Lagerhülse 3 bildet eine Federarmbasis für daran angebundene sich nach vorne bis zur Stecköffnung 6 erstreckende, etwa parallel nebeneinander auf Abstand angeordnete Federarme 7, wobei die Federarme 7 die Kontakthülse 8 der Rundsteckhülse bilden. Die Federarme 7 ergeben sich durch aus der Platine (Fig. 1) ausgeschnittene Langlöcher 9, deren Länge der Länge der Federarme 7 entspricht. Die Langlöcher 9 können - wie abgebildet - flaschenförmig oder oval sein. Am stecköffnungsseitigen Ende der Federarme 7 ist der Kragen 10 als ein sich quer zur Längsachse 4 erstreckendes Materialband angebunden. Die Breite des Kragens 10, d.h. seine axiale Erstreckung beträgt - wie abgebildet - etwa 1/4 der Länge der Federarme 7. In der Biegelinie 11 wird der Kragen 10 nach außen umgebogen und dicht auf die stecköffnungsseitigen Endbereiche der Federarme 7 geschlagen. Dabei ist die Biegelinie 11 derart angeordnet, daß in der Stecköffnung 6 keine scharfen Kanten auftreten (Fig. 3). Die Platine wird derart gerollt, daß die Stoßkanten 12 des Kragens 10 und der Lagerhülse 3 gegeneinanderstoßen. Die damit verbundene Rollarbeit ist sehr gering, weil der Bereich der Federarme 7 radial nach innen ausweichen kann und dabei keinen nennenswerten Widerstand entgegensetzt und der Kragen 10 ohne Materialverzug eingerollt werden kann, bis die Stoßkanten 12 aneinanderstoßen.The bearing sleeve 3 forms a spring arm base for spring arms 7 connected to it, which extend forward to the plug opening 6 and are arranged approximately parallel to one another at a distance, the spring arms 7 forming the contact sleeve 8 of the round plug sleeve. The spring arms 7 result from elongated holes 9 cut out of the circuit board (FIG. 1), the length of which corresponds to the length of the spring arms 7. The elongated holes 9 can - as shown - be bottle-shaped or oval. At the insertion opening end of the spring arms 7, the collar 10 is connected as a material band extending transversely to the longitudinal axis 4. The width of the collar 10, i.e. its axial extent is - as shown - about 1/4 of the length of the spring arms 7. In the bending line 11, the collar 10 is bent outwards and struck tightly onto the end regions of the spring arms 7 on the insertion opening side. The bending line 11 is arranged such that no sharp edges occur in the insertion opening 6 (Fig. 3). The board is rolled such that the abutting edges 12 of the collar 10 and the bearing sleeve 3 abut each other. The associated rolling work is very low because the area of the spring arms 7 can deflect radially inwards and in the process does not offer any appreciable resistance and the collar 10 can be rolled in without material distortion until the abutting edges 12 meet.

Die Federarme 7 laufen geringfügig konisch aufeinander zu, so daß der Außendurchmesser des Kragens 10 mit dem Außendurchmesser der Lagerhülse 3 übereinstimmt und demgemäß ihre Mantelflächen axial zueinander fluchten.The spring arms 7 taper towards one another slightly, so that the outer diameter of the collar 10 corresponds to the outer diameter of the bearing sleeve 3 and accordingly their outer surfaces are axially aligned with one another.

Nach einer besonderen Ausführungsform der Erfindung sind die Federarme 7 nach innen zur Längsachse 4 hin und auch quer dazu geringfügig nach innen durchgebogen, so daß sie an diesen Kontaktstellen 13 zum Innenraum hin ballig . ausgebildet sind und jeweils eine punktförmige Kontaktierung für den strichpunktliniert in Fig. 3 angedeuteten Stift 14 und damit eine definierte Kontaktstelle gewährleisten. Diese Durchbiegung befindet sich zweckmäßigerweise in Richtung auf die Lagerhülse 3 kurz hinter dem Kragen 10, so daß die Kontaktstellen 13 soweit wie möglich vorne im Bereich der Stecköffnung 6 liegen.According to a particular embodiment of the invention, the spring arms 7 are bent inwards towards the longitudinal axis 4 and also slightly inwards transversely thereto, so that they are spherical at these contact points 13 towards the interior. are formed and each ensure punctiform contacting for the pin 14 indicated in dash-dot lines in FIG. 3 and thus ensure a defined contact point. This deflection is advantageously in the direction of the bearing sleeve 3 just behind the collar 10, so that the contact points 13 are as far as possible in the front in the region of the plug opening 6.

Die Erfindung erbringt insoweit eine Rundsteckhülse mit den gewünschten weichen Federkennlinien, bewirkt durch relativ lange Federarme, verbunden mit einer definierten Kontaktstelle. Andererseits gewährleistet der Kragen die erforderliche Trittfestigkeit und Versteifung für das Einsetzen in eine Kammer der Steckkupplung und außerdem eine gewünschte Versteifung der Federarme nach Art einer Überfeder. Die Kräfte, die zur Herstellung der Rundsteckhülse aus der Platine erforderlich sind, sind extrem gering.In this respect, the invention provides a circular plug-in sleeve with the desired soft spring characteristics, caused by relatively long spring arms, connected to a defined contact point. On the other hand, the collar ensures the necessary stiffness and stiffening for insertion into a chamber of the plug-in coupling and also a desired stiffening of the spring arms in the manner of a spring. The forces required to manufacture the circular receptacle from the board are extremely low.

Die erfindungsgemäße Rundsteckhülse kann auf einfache Weise mit einer Überfeder 14a bestückt werden, so daß man als Material für die Rundsteckhülse gegebenenfalls ein relativ weiches noch leichter verformbares, elektrisch gut leitendes Metall einsetzen kann. Die Überfeder 14a z.B. aus Stahl verstärkt bzw. optimiert in diesem Fall die Federkräfte. Die Überfeder 14a erstreckt sich von der Anbindungsstelle der Federarme 7 bis zum Kragen 10 und besteht im einfachsten Fall aus einer runden zylindrischen Hülse, die auf der Kontakthülse 8 der Rundsteckhülse sitzt, wobei die Federarme 7 unmittelbar hinter ihrer Anbindung an die Lagerhülse 3 um z.B. eine Materialstärke nach innen durchgesetzt sind, so daß eine Widerlagerkante 15 für die Überfeder 14a gebildet wird. Die Überfeder 14a findet ihr anderes Widerlager an der Unterkante 16 des Kragens 10. Da das Material der Überfeder 14a dünner ist als das Material der Rundsteckhülse im Bereich der Kontakthülse 8, trägt die Überfeder 14a nicht auf und stört nicht.The circular receptacle according to the invention can be easily equipped with an over-spring 14a, so that a relatively soft, more easily deformable, electrically highly conductive metal can optionally be used as the material for the circular receptacle. The spring 14a made of steel, for example, strengthens or optimizes the spring forces. The spring 14a extends from the connection point of the spring arms 7 to the collar 10 and, in the simplest case, consists of a round cylindrical sleeve which sits on the contact sleeve 8 of the circular plug-in sleeve, the spring arms 7 immediately behind their connection to the bearing sleeve 3 by, for example, one Material thickness are penetrated inwards, so that an abutment edge 15 is formed for the spring 14a. The over-spring 14a finds its other abutment on the lower edge 16 of the collar 10. Since the material of the over-spring 14a is thinner than the material of the circular plug-in sleeve in the area of the contact sleeve 8, the over-spring 14a is not bulky and does not interfere.

Vorzugsweise ist an der Überfeder 14a mindestens ein Rastfederarm 17 vorgesehen, der aus dem Mantel der Hülse der Überfeder 14a freigeschnitten ist und sich schräg nach außen vom kragenseitigen Endbereich zur Lagerhülse 3 hin erstreckt, wobei der Basisbereich 18 der Überfeder 14a, an den der Rastfederarm 17 angebunden ist, zweckmäßigerweise sickenförmig nach außen durchgesetzt ist. Die Sicke 18a überragt dabei jedoch nicht die Manteloberfläche des Kragens 10 bzw. der Lagerhülse 3 und die Widerlagerkante 15 ragt soweit nach innen, daß der Rastfederarm 17 ausreichend Raum vorfindet,so daßer in diesen Raum ausweichen kann, wenn die Rundsteckhülse in eine Kammer einer Steckkupplung eingeschoben wird.At least one detent spring arm 17 is preferably provided on the over-spring 14a, which is cut free from the jacket of the sleeve of the over-spring 14a and extends obliquely outwards from the collar-side end region to the bearing sleeve 3, the base region 18 of the over-spring 14a to which the detent spring arm 17 is connected, is appropriately penetrated bead-like to the outside. The bead 18a does not, however, protrude beyond the jacket surface of the collar 10 or the bearing sleeve 3 and the abutment edge 15 projects so far inward that the detent spring arm 17 finds sufficient space so that it can move into this space if the circular plug-in sleeve enters a chamber of a plug-in coupling is inserted.

Nach einer anderen Ausführungsform der Erfindung, die in den Fig. 5 und 6 dargestellt ist, sind mehrere Rastfederarme 17a einstückig an den Kragen 10 angebunden. Vorzugsweise sind ebenso viele Rastfederarme 17a vorgesehen wie Federarme 7, wobei die Rastfederarme 17a praktisch in Verlängerung der Federarme 7 angeordnet sind (Fig. 5). Die Rastfederarme 17a sind etwas kürzer ausgeführt als die Federarme 7 und die Federarme 7 weisen in ihrem Anbindungsbereich eine Durchsetzung 19 um mindestens eine Materialstärke nach innen auf, so daß auch die Rastfederarme 17a beim Einsetzen der Rundsteckhülse in eine Kammer der Steckkupplung radial soweit ausweichen können, daß sie nicht überstehen und somit keine Verletzung der Dichtelemente der Kammer verursachen können.According to another embodiment of the invention, which is shown in FIGS. 5 and 6, a plurality of detent spring arms 17a are integrally connected to the collar 10. Preferably as many locking spring arms 17a are provided as spring arms 7, the locking spring arms 17a are arranged practically in extension of the spring arms 7 (Fig. 5). The detent spring arms 17a are designed to be somewhat shorter than the spring arms 7 and the spring arms 7 have a penetration 19 in their connecting area by at least one material thickness, so that the detent spring arms 17a can also radially deflect as far as the circular plug-in sleeve is inserted into a chamber of the plug-in coupling, that they do not survive and thus can not cause damage to the sealing elements of the chamber.
