Definitions

  • the invention relates to a rotatable plug-in coupling for connecting a suction hose provided with electrical conductors to a vacuum cleaner housing, in which plug-in coupling provided in or on the suction hose electrical lines via a movable contact arrangement, comprising a plug-in coupling sleeve connected to the suction hose and a coupling receptacle provided on the vacuum cleaner housing arranged slip rings and sliding contacts are electrically connected to a circuit in the vacuum cleaner housing, the slip rings and sliding contacts simultaneously forming the mechanical separation point of the circuit in the plug-in coupling.
  • Such a coupling is known from DE-AS 17 28 486.
  • two slip rings are arranged at an axial distance on the inner circumference of the clutch receptacle provided on the vacuum cleaner housing.
  • it In order to be able to insert the coupling sleeve into the coupling receptacle, it has corresponding grooves extending in the axial direction, through which the radially projecting contact pins can be pushed as far as the slip rings.
  • Such a design of a plug-in coupling has various disadvantages.
  • the radially projecting contact pins are constantly exposed to the risk of damage.
  • the slip rings located on the inner circumference of the clutch holder can easily get dirty.
  • the coupling sleeve of the suction hose can only be inserted into the coupling receptacle in certain positions. Each time a coupling sleeve is inserted into the coupling receptacle, one contact pin slides across the one slip ring, which can cause annoying grooves.
  • the axial spacing of the slip rings results in a relatively large axial length of the coupling parts. As a result of this length, when the suction hose is pulled transversely to the longitudinal direction of the coupling, high moment forces occur within the coupling.
  • the invention has for its object to provide a plug coupling of the type described, which does not have these disadvantages.
  • the object is achieved according to the invention in that the slip rings are arranged in the radial direction concentrically on the part of the coupling sleeve which can be inserted into the coupling receptacle and the sliding contacts in the coupling receptacle are axially movable under spring force.
  • the slip rings are completely removed from the area exposed to dirt.
  • the parts of the sliding contact arrangement no longer slide over one another, so that no damage can occur. Even parts protruding beyond the outer contour and thus exposed to danger are not present in the coupling design described.
  • the slip rings arranged radially concentrically to one another result in a corresponding reduction in the axial length of the coupling parts.
  • slip rings are arranged on an annular carrier which can be plugged onto the outside of an inner tube of the coupling sleeve and can be fixed in position on the inner tube.
  • the slip rings can be held very securely by integrally formed fastening tabs which are inserted and caulked on the side opposite the grinding side through corresponding openings in the carrier.
  • the sliding contacts are expediently also arranged on a separate contact carrier.
  • the sliding contacts on the contact carrier can be clamped accordingly by a three-point support.
  • the sliding contacts are slightly adjusted by the slip rings against the tension on the contact carrier. This is made possible by the freedom of movement in the contact carrier.
  • a suction hose 3 is inserted into the coupling receptacle 2 with a coupling sleeve 5 arranged at one end and is rotatably held by a locking device 4 not shown in detail in the drawing, for example by the DE-GM 85 22 551 known.
  • the coupling sleeve 5 is angled according to the connection of the suction hose 3 on the top of the vacuum cleaner housing 1.
  • the coupling sleeve 5 has an inner tube 6 which opens into a tubular part 7 of the coupling receptacle 2.
  • the inner tube 6 is concentrically surrounded by a tube extension 8 which is open towards the end of the inner tube and which engages with its free end in the coupling receptacle 2 which is correspondingly enlarged towards the outside.
  • annular space 9 which serves to receive the latching device 4 and a carrier 10 for slip rings 11 and 12 which are inserted into corresponding grooves 13 and 14 of the carrier 10.
  • the carrier 10 is pushed onto the inner tube 6 on the outside and is held on the inner tube 6 by a slide 16 provided with claws 15.
  • stop ribs on the tube extension 8 are used, which also ensure a minimum play for easy actuation of the locking device 4.
  • the carrier 10 is secured against rotation by means of a radially projecting pin 38, which engages in a corresponding slot in the wall of the coupling sleeve 5, which slot is not visible in the drawing. Through this pin 38, the correct positioning of the carrier with respect to the electrical connection of the slip rings 11 and 12 also takes place at the same time.
  • the arrangement of the slip rings 11 and 12 in the grooves 13 and 14 protects them against deformation.
  • the assembly of the slip rings 11 and 12 is very simplified because they only need to be inserted into the chamfered grooves 13 and 14.
  • the axial holding of the slip rings 11 and 12 in the grooves 13 and 14 takes place by means of fastening tabs 17, which are inserted into openings 18 provided on the carrier 10 and caulked in these openings 18, as shown in FIG. It is particularly advantageous that the openings 18 flare outwardly.
  • the connection Intermediate lines 19 to the slip rings 11 and 12 take place on the side of the slip rings 11 and 12 facing the groove bottom.
  • cutouts 20 are provided on the carrier, which allow the intermediate lines 19 to pass through (FIG. 3).
  • Sliding contacts 21 and 22 which cooperate with the slip rings 11 and 12 are arranged on a separate contact carrier 23 which can be connected to the vacuum cleaner housing 1 in the area of the coupling receptacle 2.
  • the sliding contacts 21 and 22 consist of S-shaped bent metal strips, at one end 24 of which a feed line 26 is connected. With their other end 25, the sliding contacts 21 and 22 rest against the slip rings 11 and 12 and thus establish the electrical connection.
  • the sliding contacts 21 and 22 are shaped so that in their rest position, i.e. when the coupling sleeve 5 is not inserted, are braced by a three-point support.
  • This three-point support is by a stop bar 27, on which the sliding contacts 21 and 22 each abut at one end 24, a support bar 28 on which the sliding contacts 21 and 22 rest in the area of their one S-arm and by locking tongues 29, which are elastic Tabs 30 are formed and on which the sliding contacts 21 and 22 abut in the area of their other S-bend.
  • a holding cam 27a is formed on each stop bar, which extends through a corresponding opening in one end 24 of the sliding contacts 21 and 22 and thus secures the relevant sliding contact 21 or 22 in the vertical direction.
  • a stop tongue 27b is punched on each sliding contact, the free end of which rests laterally on the support strip 28 and thereby secures the respective sliding contact 21 or 22 in the horizontal direction.
  • connection box 34 connected to the suction hose 3
  • a printed circuit board 35 is inserted, on which the intermediate lines 19 are connected to control lines 36 laid in the jacket of the suction hose 3.
  • a line channel 37 for the intermediate lines 19 is formed by a cover 39 which can be snapped onto the locking sleeve 5 integrally formed on the coupling sleeve 5, so that there are no longer any exposed line parts.
  • the cover 39 engages with a locking tab 40 in an insertion opening 41 of the terminal box 34.
  • the junction box 34 is not only closed, but the intermediate lines 19 are secured against twisting.
