Description
<B>(Zusatzpatent zum Hauptpatent 375 410)</B> <B>Elektrischer Stecker</B> Die Erfindung bezieht sich auf einen elektrischen Stecker aus Metallblech, der an dem einen Ende ei nen zylindrischen oder tonnenförmigen, sich nach vorn verjüngenden, hohlen Teil aufweist und an des sen anderem Ende Lappen angeordnet sind, um einen Ring mit etwas grösserem Durchmesser als der zylin drische Teil zu bilden, wobei dazwischen U-förmig hochgebogene Lappen vorgesehen sind, um diese an ein durch den Ring verlaufendes Kabel anzudrük- ken.
Gemäss der vorliegenden zusätzlichen Erfindung weist bei einem solchen Stecker der die Zwinge bil dende Teil an der Unterseite eine Längssicke auf, die der Längsachse des Steckers näher liegt als die Steckerteile um die Sicke herum.
Eine Ausführungsform eines erfindungsgemäs- sen Steckers soll im nachstehenden unter Bezugnah me auf die Zeichnungen näher erörtert werden. Von den Figuren zeigen: Fig. 1 eine perspektivische Darstellung eines Steckers; Fig. 2 eine Seitenansicht der in Fig. 1 wieder gegebenen Ausführungsform; Fig. 3 eine Ansicht von unten; Fig. 4 eine Ansicht vom einen Ende her betrach- tet; Fig. 5 eine Ansicht vom anderen Ende her be trachtet; Fig. 6 eine Draufsicht;
Fig. 7 und 8 eine Draufsicht und die entspre chende Ansicht, bei denen der Stecker an ein Kabel angedrückt ist; Fig. 9 einen Querschnitt durch die Andruckzwin ge entsprechend der Schnittlinie 9-9 der Figuren 7 und B. Der Stecker ist aus einem gestanzten Blechteil gerollt und hat einen zylindrischen, sich nach vorne verjüngenden, hohlen oder teilweise kugelförmigen Vorderteil 1, der im wesentlichen von kreisförmigem Querschnitt ist.
Am anderen Ende des Steckers ist ein ringförmiger Teil 2 oder ein Zwingenteil vorge sehen, der zu einem ringförmigen Teil 2 gebogen werden kann wobei der Ring-Durchmesser derselbe ist wie der Querschnittsdurchmesser des zylindri schen Vorderteiles. Zwischen dem ringförmigen Teil 2 und dem Vorderteil 1 befindet sich eine An- drückzwinge 3, welche an das Vorderende des Ka bels angedrückt wird, das in den Stecker durch den Ring 2 eingeführt wird. Der Ring 2 und der Vorder teil 1 liegen koaxial zueinander und bilden ein zy lindrisches Umfangsprofil, innerhalb dessen sämtli che Teile des Steckers liegen.
Der Zwingenteil 3 bildet eine Zwinge, welche innerhalb der Umrandung des zylindrischen Stecker profiles liegt, wie Fig. 7 und 8 erkennen lassen.
Der insoweit beschriebene Stecker entspricht im wesentlichen der im Hauptpatent beschriebenen Aus führungsform.
Die Unterseite des die Zwinge bildenden Mit telteiles 3 hat in der Längsrichtung eine Sicke 4, die sich in Richtung auf die Längsachse des Steckers stärker erstreckt als diejenigen Teile, welche um die Sicke 4 herum liegen. Die Sicke 4 wird hergestellt bei der Herstellung des Steckers selbst und vor dem Andrückvorgang an das Kabel. Die Sicke er leichtert die Anhäufung von Metall in dem die Zwin ge bildenden Mittelteil 3 innerhalb des Zylinder mantels, der durch den Ring 2 und den Vorderteil 1 als Querschnittsprofil definiert wird, wobei eine grössere Metallmenge in dem die Zwinge bildenden Mittelteil erzielt wird, als bei der zuvor erörterten Ausführungsform der Fall war.
Die Sicke 4 hat fer ner zur Folge, dass der Stecker eine höhere Festig keit gegen Verbiegungen erhält, war wichtig im Hin blick darauf ist, dass unter Umständen der Stecker in seine Steckerhülse unter Anwendung einer nicht axial wirkenden Kraft eingesteckt wird oder aus der Hülse herausgezogen wird. Es ergibt sich auf diese Weise eine beträchtlich höhere Widerstandsfähigkeit des Steckers in seinem die Zwinge bildenden Mittel teil 3, d. h. zwischen dem Vorderteil 1 und dem ringförmigen Teil 2.
Dadurch, dass die Sicke 4 gebildet wird, bevor ein Andrücken an das Kabel stattfindet wird, wie Fig. 9 zeigt, das erforderliche nach innen Rollen der Zwingenseitenarme 3 verringert. Zweckmässigerwei- se wird die Sicke 4 hergestellt, wenn der Stecker noch ein flacher Stanzteil ist;
es kann jedoch dabei ein weiteres Eindrücken der Sicke auch erfolgen, wenn der Stecker an das Kabelende angedrückt wird und die Verbindung des Leiters mit der Zwinge 3 er folgt. Zweckmässigerweise dient dabei die Sicke 4 auch als ein Mittel, um die Lage des Steckers in Be zug auf das zur Anwendung gelangende Andrück- gesenk festzulegen, wobei das Gesenk einen Vor sprung haben kann, der in die vorgeformte Sicke 4 eingreift.
Der ringförmige Teil 2 hat zweckmässigerweise nach innen gerichtete scharfe Zähne nach Art eines Nadelloches, wobei die Zähne einen gewissen Ab stand voneinander haben und in die Isolation 5 des Kabelmantels 6 eingreifen beziehungsweise dieselbe durchstechen.
Derartige Zähne 7 und 8 können da durch hergestellt werden, dass ein entsprechend scharf zulaufendes Instrument in den aus Blech be stehenden Stanzteil eingestossen wird, so dass das Blech durchstochen und am Lochrand aufgeworfen wird, ohne dass das Einstechinstrument vollständig das Blech durchsetzt. Auf diese Weise ergibt sich eine kleine Öffnung, die von einer Mehrzahl zuge- gespitzter Zähne begrenzt wird.
Bei der dargestellten Ausführungsform hat die eingeprägte Warze 8 nach aussen sechseckigen Querschnitt, während die Zähne 7 an der Innenseite der Zwinge dreieckig sind, wo bei zur Herstellung der Zähne ein entsprechend ge formtes Werkzeug benutzt wird.
<B> (Additional patent to main patent 375 410) </B> <B> Electrical plug </B> The invention relates to an electrical plug made of sheet metal, which at one end has a cylindrical or barrel-shaped, forwardly tapering, has a hollow part and at the other end of which tabs are arranged to form a ring with a slightly larger diameter than the cylindrical part, with U-shaped upwardly bent tabs being provided in between in order to press them against a cable running through the ring .
According to the present additional invention, in such a connector, the part forming the ferrule has a longitudinal bead on the underside which is closer to the longitudinal axis of the plug than the plug parts around the bead.
An embodiment of a connector according to the invention will be discussed in more detail below with reference to the drawings. The figures show: FIG. 1 a perspective illustration of a plug; FIG. 2 shows a side view of the embodiment given again in FIG. 1; 3 is a view from below; 4 is a view viewed from one end; Fig. 5 is a view from the other end be sought; Fig. 6 is a plan view;
7 and 8 are a plan view and the corre sponding view in which the connector is pressed against a cable; Fig. 9 shows a cross section through the Andruckzwin ge according to the section line 9-9 of Figures 7 and B. The plug is rolled from a stamped sheet metal part and has a cylindrical, forwardly tapering, hollow or partially spherical front part 1, which is essentially from circular cross-section.
At the other end of the plug, an annular part 2 or a ferrule part is easily seen, which can be bent to an annular part 2 wherein the ring diameter is the same as the cross-sectional diameter of the cylindri's front part. Between the ring-shaped part 2 and the front part 1 there is a pressure clamp 3 which is pressed against the front end of the cable which is inserted into the plug through the ring 2. The ring 2 and the front part 1 are coaxial with each other and form a zy-cylindrical circumferential profile within which lie all che parts of the connector.
The clamp part 3 forms a clamp which lies within the border of the cylindrical plug profile, as can be seen in FIGS. 7 and 8.
The connector described so far corresponds essentially to the embodiment described in the main patent from.
The underside of the ferrule forming with telteiles 3 has a bead 4 in the longitudinal direction, which extends more in the direction of the longitudinal axis of the plug than those parts which are around the bead 4 around. The bead 4 is produced during the production of the connector itself and before the pressing process onto the cable. The bead it facilitates the accumulation of metal in the Zwin ge forming middle part 3 within the cylinder jacket, which is defined by the ring 2 and the front part 1 as a cross-sectional profile, with a greater amount of metal in the middle part forming the ferrule is achieved than with the previously discussed embodiment was the case.
The bead 4 also has the consequence that the connector has a higher strength against bending, which was important in view of the fact that the connector may be inserted into its connector sleeve using a non-axially acting force or pulled out of the sleeve becomes. There is in this way a considerably higher resistance of the plug in its means forming the ferrule part 3, d. H. between the front part 1 and the annular part 2.
Because the bead 4 is formed before the cable is pressed against it, as FIG. 9 shows, the required inward rolling of the clamp side arms 3 is reduced. The bead 4 is expediently produced when the plug is still a flat stamped part;
However, the bead can also be pressed in further when the plug is pressed against the cable end and the connection of the conductor with the clamp 3 follows. The bead 4 expediently also serves as a means to fix the position of the plug in relation to the pressure die used, the die being able to have a protrusion which engages in the preformed bead 4.
The annular part 2 suitably has inwardly directed sharp teeth in the manner of a needle hole, the teeth being a certain distance from each other and engage in the insulation 5 of the cable jacket 6 or pierce the same.
Such teeth 7 and 8 can be produced by inserting a correspondingly sharp instrument into the stamped part made of sheet metal, so that the sheet is pierced and thrown up at the edge of the hole without the piercing instrument completely penetrating the sheet. This results in a small opening that is delimited by a plurality of pointed teeth.
In the illustrated embodiment, the embossed wart 8 has an outwardly hexagonal cross-section, while the teeth 7 are triangular on the inside of the ferrule, where a correspondingly shaped tool is used to produce the teeth.
