Definitions

  • the invention relates to a plug-in device for cable connections in the high-voltage high-current range according to the preamble of claim 1.
  • plug connections e.g. to be designed as an inner cone plug-in connection in which the contact between a socket part and a plug part takes place via a lamellar spring washer.
  • this is a relatively sensitive and expensive component that can only compensate for the differences in the distance to be bridged to a very modest extent with its spring lamellae, so that one is forced to adhere to tight manufacturing tolerances in the outer diameter of the plug part and in the inner diameter of the socket part.
  • the object of the invention is to provide a contacting device according to the preamble of claim 1, which is constructed in such a way that it not only enables good contact making, but is also suitable to compensate for larger manufacturing tolerances with a simple structure and which also enables the contact elements to be connected to one another lock that an unwanted opening of the contact is excluded.
  • At least one circumferential ring groove is formed in the coaxial area between the plug part and the socket part on the inner surface of the socket part and the outer surface of the plug part, and two ring grooves opposite each other in the plug end position jointly accommodate a spring ring, If the spring washer is designed appropriately, it is possible to achieve a latching between the contact parts.
  • at least one spring ring is provided as an open or closed spiral spring ring, which lies in an associated annular groove and in which all spiral spring windings have a predetermined one-sided inclination along the circumferential direction of its outer, radial circular ring, so that they have this inclination under radial pressure on the spiral spring ring enable reinforcing, defined resilient tilting movement.
  • the spiral spring ring is formed from an elongated spiral spring, the two ends of which may be connected to one another. If the associated ring groove lies on a cylindrical inner surface, connecting the two spiral spring ends is superfluous and the spiral spring can be inserted as an open spiral spring ring.
  • a major advantage of the new plug-in device is also that the spiral spring ring is dimensioned in relation to the dimensions of the contact elements that it can bridge larger differences in the annular gap widths to compensate for manufacturing tolerances than is possible with a lamellar spring washer.
  • spiral spring ring can be inserted into an annular groove of the socket part, which secures it against axial displacement.
  • the plug part must then be provided with a locking cam ring forming the corresponding annular groove, which has a locking flank and an unlocking flank.
  • the spiral spring ring can also be inserted into an annular groove in the plug part, which secures it against axial displacement.
  • the plug part must be provided with a locking cam ring which has a locking flank and an unlocking flank.
  • the locking flank and the unlocking flank are each designed as sliding bevels, which make it easier to slide the spiral spring ring for locking when plugging in, and unlocking when pulling out the plug part.
  • the desired locking and unlocking forces can be set for given diameters.
  • the locking cam ring is designed as a separate part and as such is positioned in the correct place in the standardized socket with a cylindrical inner surface and is fastened by adhesive.
  • spiral spring ring is designed and interacts with the plug part and the socket part in such a way that it enables both locking and contacting between these two parts.
  • the plug device can also be constructed in such a way that the spiral spring ring interacts with the plug part and the socket part in such a way that it only or mainly enables locking and a second spring ring, which is preferably designed as a lamellar spring ring, takes over the contacting.
  • a spring ring could be specially dimensioned in such a way that it is particularly well suited for latching, while a material could be selected for the other spring ring that ensures particularly good contacting.
  • an inner cone plug device has an inner cone plug with a plug part 1 a, a housing 23 and a field control cone 22 which encloses a cable end 20 with a conductor end 19 and is inserted into a socket part 2 a with its insulating body 21.
  • a spiral spring ring 3a is provided which bridges an annular gap 5 lying between the two parts.
  • the ring is created by connecting the two free ends of an elongated spiral spring, the actual peculiarity of which is the inclined spiral spring windings 4a.
  • the spiral spring windings 4a tilted in a direction of rotation 12 enable a spring effect which is caused by a change in the respective tilting position of the individual spiral spring windings 4a.
  • the coil spring windings 4a are more or less compressed. This process is illustrated in FIG. 4, in which the spring force P is shown as a function of the spring travel. In its position E, the spiral spring has only covered a short spring travel, which corresponds to a slight compression or inclination of the spring windings.
  • a spiral spring ring 3a inserted into an annular groove 6 is suitable for providing the necessary contact.
  • the spiral spring washer 3a plunges in its relaxed, ie not upset form, so far into an axially fixing annular groove 6 that it cannot slide out of it if an axial pressure is exerted on it when it is attached.
  • the depth of the annular groove 6 is dimensioned such that the completely compressed or compressed spiral spring ring 3a can be accommodated in it. With appropriate dimensioning, a large spring travel can be achieved with the spiral spring ring 3a, which makes it possible to compensate for large or very different differences between the outer diameter of the plug part 1a and the inner diameter of the socket part 2a.
  • FIG. 5 to 7 show different variants of the contact area of an inner cone connector for high-voltage power cables, as shown in Fig. 1.
  • an inner contact element 1 designed as a plug part 1a and an outer contact element 2 designed as a socket part 2a, as well as a locking cam ring 18 with a locking flank 14, which leads via a cam tip 18a to an unlocking flank 15.
  • a spiral spring washer 3a lying in an annular groove 6 of the socket part 2a is initially compressed by the locking flank 14 of the locking cam ring 18 onto a compression profile 17 when the plug part 1a is inserted, but can, after the cam tip 18a in an annular groove 6b of the plug part 1a, revert to its latching profile 16 relax and thereby lock in this position.
  • 5 shows this locking position, the plug part 1a in FIG. 6 is in an intermediate position on the cam crest 18a, in which the spiral spring ring 3a is strongly compressed and then slides either for unlocking via the unlocking flank 15 or for locking via the locking flank 14 .
  • the spiral spring washer 3a is designed in such a way that it simultaneously ensures the locking and the contacting, in the embodiment according to FIG. 7 it serves only or primarily for locking and leaves the contacting to one Another spring ring 3, which is designed here as a lamellar spring ring 3b is. However, this presupposes that the annular gap 5 to be bridged has only relatively small tolerances. Otherwise, a suitably dimensioned, well-conductive spiral spring washer 3a will also be used for contacting.
