Definitions

  • the invention relates to a rotary coupling for multi-conductor cables according to the preamble of the main claim.
  • Such couplings are known in various designs. They are generally used in electrical devices that are in use - e.g. due to frequent gripping - are exposed to constant or frequent twisting, which would lead to a twisting of the connection cable without such a rotating coupling.
  • the invention overcomes the disadvantages described by a new rotary coupling, which is designed according to the characterizing part of the main claim and which simultaneously optimizes the electrical contacting and the mechanical rotary bearing completely independently of it, and in addition by the releasable locking of the rotating part an unproblematic assembly and interchangeability of the Connection cable is guaranteed.
  • the rotary coupling according to the invention has a coupling sleeve 10 which is generally firmly inserted into the housing of the electrical device to be connected or, in a special embodiment, can also be part of the device housing.
  • the two contact springs 5 and 12 which preferably have the approximately equilateral triangular shape shown in FIG. 4, are firmly inserted into this coupling sleeve 10.
  • the connector 15 inserted concentrically into the coupling sleeve 10 carries two correspondingly arranged slip rings 6 and 7, on which the contact springs 5 and 12 bear in an electrically conductive manner.
  • the kink protection sleeve 1 and the connecting cable 2 guided therein form with the connecting piece 15 an endlessly rotatable structural unit in the coupling sleeve 10.
  • the connector 15 is designed as a rotationally symmetrical body and carries the two slip rings 6 and 7 on cylindrical sections 15.1 and 15.2 of different circumference.
  • the two cylindrical sections mentioned are connected to one another by a conical section 15.3, which facilitates the self-centering insertion of the network-side connector 15 into the device-side coupling sleeve 10 during assembly.
  • the connector 15 is mounted at its two outer ends with large sliding surfaces in the coupling sleeve, with the inner end portion 18 in a recess 10.1 formed in the bottom 10.2 of the coupling sleeve 10, where it is encompassed by an annular bead 16; and with the guide section 4 on the circumferential edge 11 of the coupling sleeve 10 surrounding it.
  • the coupling sleeve 10 and the connector 15 have molded or molded locking elements in the area of their outer bearing formed by the guide section 4 and the edge 11, which lock the connector 15 to the coupling sleeve 10 coaxially rotatable but axially immovable.
  • the coupling sleeve 10 preferably carries, as a latching element, a nose 11.1 encircling the outside of its edge 11 and the connector 15 a molded-on fastening ring 3 which overlaps this nose 11.1. It has proven expedient to design the fastening ring 3 in such a way that it encircling locking lug 11.1 engages only at individual sections 17 and that it can be radially elastically deflected or stretched at these sections 17.
  • the later disassembly can be made even easier by the fact that the fastening ring 3 in the area of the sections 17 has recesses 17.1 on its outside for inserting unlocking means - for example a simple lever tool.
  • the - as already mentioned - preferably approximately triangular contact springs 5 and 12, the corners of which are expediently adapted to the inner rounding of the coupling sleeve 10, each have a connecting lug 13 and 14, which are parallel to the coupling axis through corresponding recesses in the bottom 10.1 of the coupling sleeve 10 extend and to which the device-side electrical conductor connections are connected - for example can be soldered on.
  • the connecting lugs 13 and 14 preferably start from one of the three rounded corners of the contact springs, while the contact springs are divided at one of the other two rounded corners, so that their free ends opposite each other at this division can spring together and the contact springs can be elastically deformed overall are.
  • the contact springs can be deflected radially in the region of their legs lying between the rounded corners, since they are supported only on the coupling sleeve 10 with the rounded corners and the legs run straight and freely through the interior of the coupling sleeve.
  • the inner radius of the contact springs can initially be dimensioned somewhat smaller than the outer radius of the slip rings, and when the connector with the slip rings is inserted axially into the coupling sleeve with the contact springs, each of the three contact spring legs is pressed radially outward in the shape of an arc, the resulting elastic restoring force thereby being one uniform contact pressure against the slip rings and thus a good electrical contact to the slip rings evenly distributed over the three legs.
  • the contact springs 5 and 12 on the edges of their legs 19, 20 and 21 facing the cable feed have outwardly bent sliding tabs 22, 23 and 24, which axially insert the connector 15 into the coupling sleeve and the associated radial expansion of the contact springs in that the slip rings 5 and 12 first place on the slopes of these sliding tabs and slide on them into the contact springs.
  • the axial centering achieved during assembly by the triangular shape of the contact springs 5 and 12 can be further improved in that the two equilateral-triangular contact springs are rotated relative to one another by an angle of 60 °. This arrangement also ensures that the connecting lug 14 of the contact spring 5 can be guided past the contact spring 12 at a sufficient safety distance.
  • a particular advantage of the present invention has been found to be that a rotary coupling that is reliable under all practical conditions can be realized, which has exceptionally small external dimensions and nevertheless allows the transmission of relatively high electrical powers. Furthermore, the particularly smooth and wear-resistant rotary bearing of the coupling according to the invention should be emphasized.
