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.
