Description

  • The invention relates to a circular connector for shielded electrical cable with a carrier body arranged in an insulating body and a cable gland, consisting of a pressure / clamping part and a metallic screw, wherein when screwing the screw on the carrier body, the pressure / clamping member presses against the insulating body.
  • Such a connector is required in order to be able to use shielded electrical cables with a quick connection technology instead of hitherto unshielded cables and lines, which are connected to each other in non-critical areas by means of quick connection technology.
  • Connectors are known from the prior art, which pass either their shielding over a metallic or metallized shell or a center conductor to a mating connector.
    So is out of the DE 198 37 530 C1 a cable entry is known in which a shielded cable by means of an electrically conductive seal ring is contacted with an electrically conductive pressure screw.
  • The invention is therefore based on the object to form a connector of the type mentioned in that in the field of quick connect technology connectors with shielded electrical cables or conductors can be used, with either the shield on the metallic outer shell, an integrated center conductor or at the same time both conductive parts can be passed on. According to different specifications, shields are to be realized via the center conductor or the outer shell.
  • This object is achieved in that for contacting a cable shield of the electrical conductor, a contact element is provided, wherein the contact element is arranged on the side facing the cable connection side of the insulator, that the contact element is provided as a flat bent part with a bent, resilient end over engages a projection provided in a recess disposed axially in the outer wall of the insulating body, that the contact element is provided with an opening into which the cable shield is inserted, wherein the cable shield is received in the recess and clamped with the resilient end, and that the contact element with the bent, resilient end is arranged so that presses the bending edge of the resilient end against the inner wall of the screw when screwing the screw.
  • Advantageous embodiments of the invention are specified in claims 2-5.
  • The advantages achieved by the invention are, in particular, that an already known connector by simple measures according to the invention off or can be retrofitted, and that when using a contact element, the shielding of an electrical conductor via an electrically conductive outer shell or z. B. is arranged in the center of the connector ladder or both forwarded to a mating connector. In this case, a specially shaped contact element is integrated into an already known insulating body.
    In this case, one side of the contact element to a built-in insulating contact part, while the other side is provided with an opening for the shielding braid to be twisted shielded electrical cable and a bent resilient contact end which clamps the Abschirmgeflecht in a recess provided in the insulating body.
  • The bent resilient contact end is shaped so that it comes into contact with a metallic screw sleeve surrounding the connector.
  • An embodiment of the invention is illustrated in the drawing and will be explained in more detail below. Show it:

    Fig. 3
    an isometric view of a complete circular connector, and
    Fig. 4
    a detailed representation of the contact between the contact element and the sleeve.
  • In the Fig.1 is shown in an exploded perspective view of a complete inventive connector 1. Starting from the bottom left to the top right, the following parts are shown. First, a metallic plug-in part 2, which can be screwed onto a mating connector, is latched with an insulating carrier body 3, in which contact elements, not further shown here, are held for signal transmission.
    Especially emphasized and shown is the contact part 10, the insulation displacement terminal 19 has at the connection-side part 14 in a corresponding, slot-shaped receptacle 21 of an insulating body 20. (See also Fig. 2a ) On the insulating body, in which conductor guide channels 22 are provided, in which signal-carrying electrical single conductor 54 are guided, followed by a pressure / clamping member 30, with which the electrical cable 50 is secured against extract from the connector 1.
    Between the insulating body and the cable gland, a contact element 25 is inserted, which will be explained below.
    This is followed by a metallic screw sleeve 40 with which the connector is held together after screwing onto the carrier housing 3 and a shielding sleeve 45, which passes the electrical contact of the threaded sleeve 40 on the insulating carrier body 3 to the metallic plug-in part 2 with appropriate positioning.
  • In the Fig. 2a is that already in Fig. 1 indicated contact part 10 shown with its relevant items. The contact part is formed from the two sections of a plug-side part 12 and a connection-side part 14, wherein the contact part can also be made in one piece.
    The plug-side part has a plug pin 15 for contacting with a mating connector and a socket 16 into which a pin-shaped projection 17 of the connection-side part 14 can be inserted. The part 14 is held by means of a locking spring 18 in the insulating body 20. The second side of the connection-side part is designed as a cutting clamp 19, in which the contact element 25 is pressed with a bend 26 provided for this purpose.
    The contact element 25 is formed as a U-shaped flat bent part with an asymmetrically arranged round opening 29 in the central region 27, bent by 90 ° bend 26 and bent over at least 35 ° to the central region resilient end 28.
    During assembly, the contact element is contacted on the Abwinklungsseite 26 in the receptacle 21 'with the insulation displacement terminal 19 and clamped on the other side with the bent resilient end 28 in the axially arranged recess 23 in the insulating body 30.
  • In the Fig. 2b the insulating body 10 is rotated by about 180 ° and shown from the view of the pressure / clamping member 30, so that the position of the contact element 25 is made clear again on the surface of this Isolierkörperseite. It can also be seen that the axially arranged lateral recess 23 has a stepped structure and a projection 23 'is provided, around which the cable shield is to be guided, and over which engages the resilient end 28 of the contact part 25 in the recess 23 ,
  • As continues from the Fig. 2a can be seen, a collar 32 is formed on the insulating body facing side of the pressure / clamping member 30, the raised polarizing means 34 which engage in corresponding recesses 24 in the insulating body 20.
    Furthermore, a further recess 36 is provided in the collar over the entire height of the collar into which the contact element 25 extends with the bent, resilient end 28.
    The cable shield 52 is twisted before mounting the connector and threaded through the opening 29 in the contact element.
    Subsequently, the individual conductors 54 are inserted into the conductor guide channels 22 of the insulating part and the pressure / clamping part 30 is placed with the contact element 25 on the insulating body 20.
    In this case, the twisted cable shield is inserted into the axially formed on the outer wall of the insulating recess 23, wherein the bent, resilient end 28 presses the twisted cable shield into the recess.
    About the insulator protruding single conductor ends 54 and cable shielding are cut off and pushed insulating body with cable gland in the support body 3. The individual conductors guided in the conductor guide channels are cut by the insulation displacement contacts which are firmly inserted in the support body (not shown here) and at the same time an electrically conductive connection to the contact part 10 is produced. Subsequently, the screw sleeve 40 is pushed and screwed to the carrier body 3. The bent, resilient end 28 is inserted into a groove 5 provided in the carrier body and with the bending edge 28 'pressed against the inner wall 42 of the external screw, so that in addition to an internal shield hereby also a second electrically conductive outer shield via the screw 40 takes place. However, this shielding is only active when the sleeve 45 is pulled over the threaded sleeve 40 and the male part 2, so that the insulating part of the support body 3 is bridged, as in the Fig. 3 shown in the connector 1 shown completely.
  • In the Fig. 4 is shown in detail how the contact member 25 presses with its bending edge 28 'against the inner wall 42 of the metallic screw 40 to pass on the potential of the cable shield 52, which is guided through the opening 29 and abuts the resilient end 28.
    On the other side of the contact element 25, with the bend 26, which is inserted in the receptacle 21 ', the cutting clamp 19 is contacted, which is positioned in the receptacle 21.
  • It is therefore possible to transfer the potential of the shield within the connector by means of the contact part 10 and the contact element 25 or over the outer shell by means of the threaded sleeve 40 and the sleeve 45 or both measures.
