Definitions

  • the invention relates to a wire end sleeve for the stripped wire end of an electrical cable made of an electrically conductive material for making electrical contact with the wire end in an electrical connector having an electrical contact spring.
  • End sleeves are known. They are attached to the stripped wire end of an electrical cable and are intended to prevent the individual wires of a multi-wire wire from spreading out by the wire end sleeve enclosing these wires in a sleeve-like manner.
  • a known wire end sleeve consists of a V-shaped metal part before being attached to the wire end, which is crimped onto the stripped wire end of the electrical cable by rolling using a crimping tool.
  • the legs of the V-shaped metal part have teeth (so-called shark teeth) which, after crimping, onto the Interlocking wire ends.
  • wire ends of an electrical cable provided with wire end sleeves can be contacted, for example, in electrical sockets (for example lamp sockets, terminal blocks, etc.) by inserting the wire ends with their wire end sleeves into the socket, an electrical contact spring of the socket being resilient on the outside of the wire end sleeve comes to rest and thereby fixes the wire end within the socket and thereby the makes electrical contact.
  • electrical sockets for example lamp sockets, terminal blocks, etc.
  • an electrical contact spring of the socket being resilient on the outside of the wire end sleeve comes to rest and thereby fixes the wire end within the socket and thereby the makes electrical contact.
  • the disadvantage here is that the wire end is not securely fixed in the socket, since the wire end of the electrical cable can be pulled out of the socket by already low pull-out forces due to the relatively smooth surface of the wire end sleeve, without the wire end sleeve counteracting this to a sufficient extent. This is especially true when the smooth and not the top of the wire end sleeve, which is interrupted by the
  • the object of the invention is to further develop the known wire end sleeve in such a way that a wire end of an electrical cable provided with it can be securely fixed in an electrical plug connection.
  • the invention proposes that the wire end sleeve has at least one bead into which the contact spring snaps into the electrical connector after the wire end has been inserted.
  • Such a bead formed on the circumference of the wire end sleeve has the advantage that the contact spring of the plug connection can snap into it, which increases the pull-out forces when the wire end of the electrical cable is pulled out of the plug connection. Overall, the wire end of the electrical cable is thus better fixed in the plug connection.
  • the bead In a further development of the bead, it is proposed that it surrounds the wire end sleeve essentially concentrically to its longitudinal axis. This has the advantage that in everyone (Angle of rotation) position of the wire end and thus the wire end sleeve, the contact spring of the plug connection can engage in the bead and thus secure fixation within the plug connection is ensured in every position of the wire end.
  • the bead is formed on the wire end sleeve on the side opposite the toothing. This has the advantage that on one side of the wire end sleeve the toothing fulfills a certain latching function, while on the opposite side, where the wire end sleeve is normally completely smooth, the bead is responsible for the snap-in of the contact spring.
  • the bead is stamped into the wire end sleeve during the crimping onto the wire end by means of the crimping tool.
  • the formation of the bead can thus be accomplished in a simple manner during the crimping of the wire end sleeve onto the wire end, without the need for an additional operation. It is only necessary to emboss the bead in the wire end sleeve in the lifting machine without changing the V-shaped metal part of the wire end sleeve by simply modifying the lower punch and / or the upper punch.
  • the first embodiment of a wire end sleeve 1 shown in FIG. 1 is fastened on the stripped wire end 2 of an electrical cable 3.
  • the wire end sleeve 1 is crimped onto the wire end 2 by means of a corresponding crimping tool (attachment machine or hand tool).
  • a V-shaped metal part is assumed, into which the wire end 2 of the electrical cable 3 is placed.
  • its legs have so-called shark teeth, which engage during crimping and form a toothing 4, as can be seen in FIG. 1.
  • the wire end sleeve 1 has a bead 5 on the side opposite the toothing 4. This can be stamped into the wire end sleeve 1 during the crimping process using the corresponding crimping tool.
  • FIG. 2 shows a second embodiment of a wire end sleeve 1.
  • the only difference to that shown in Fig. 1 presented first embodiment consists only in that the bead 5 completely surrounds the ferrule 1, namely concentrically to the longitudinal axis A.
  • a connector is shown as a socket 6 in the form of a lamp socket.
  • two contact springs 8 are arranged in a housing 7, the ends of which are designed to be elastic.
  • the housing 7 is provided with two openings 9, through which the wire ends 2 of an electrical cable 3 fitted with wire end sleeves 1 can be inserted and contacted by the contact springs 8.
  • Fig. 3 it is only shown how an electrical cable 3 is inserted through the lower opening 9, which is provided with an end sleeve 1 of the embodiment shown in Fig. 1.
  • Fig. 3 it is only shown how an electrical cable 3 is inserted through the lower opening 9, which is provided with an end sleeve 1 of the embodiment shown in Fig. 1.
