  • a coupling for a connection of a socket and a pin-side housing is to be specified, which allows improved locking or unlocking of the self-locking connection.
  • a coupling which comprises a socket-side housing for at least one socket element and a pin-side housing for at least one pin element for imparting a contact between the socket element and the pin element.
  • the female and male members may be used to conduct an electrical current or to transmit a fluid.
  • the contact may be an electrical or a fluidic.
  • the socket-side housing and the pin-side housing extend substantially along a central axis and can be connected to one another via a plug-in movement along this central axis.

  • the object is achieved in that the coupling sleeve is guided on the finger element.
  • the coupling sleeve and the finger element are preferably by direct, i. guided by flat contact to each other.
  • the sleeve and the finger element then have corresponding contact surfaces. These contact surfaces can be arranged on projections and corresponding recesses of the two components or on the components themselves.

  • the second engagement portion 105 of the pin-side housing 1 becomes in this case introduced into the annular recess 210 of the socket-side housing 2.
  • the first engaging portion 20 of the female side housing 2 the second engagement portion 105 of the pin-side housing 1 contacted and then, in the course of the insertion movement S, the two engagement portions 20, 105 led into mesh with each other before the first engagement portion 20 the Finger element 11 touched.
  • This is made possible by the fact that the second engagement section 105 projects beyond the finger element 11 in the distal direction. This allows a good guide, which allows an increased number of mating cycles, since the material wear is minimized. Thus, the life of the clutch is extended.
  • FIG. 12 shows how now the locking lug 12 of the finger member 11 has a beveled end portion of the free end 200 of the first engagement portion 20 stripped.
  • the chamfered surface of the free end 200 serves to guide an optionally slightly radially inwardly projecting engagement element 12 radially outward on its inclined surface 120 such that the two housings 1, 2 are plugged into one another. Then, the locking lug 12 runs on the outer surface of the first engagement portion 20 in the continuation of the insertion movement S against the ramp 201.
  • FIG. 13 shows how the free end 200 of the first engagement portion 20 of the female side housing 2 accesses the first contact blade 18 and produces electrical contact between the housings 1, 2.
  • FIG. 14 shows how the first engaging portion 20 engages the first sealing member 161 and the locking lug 12 runs with its inclined surface 120 on the inclined surface of the ramp 201 and is slowly pressed radially outward, wherein the bent portion 112 (and not the entire bending portion 110) itself deformed to the height of the abutting portion of the coupling sleeve 14.
  • the bending portion 112 is a distal end portion of the beige portion 110 (see FIG. Fig. 19 ).
  • an elastic stress builds up in the shortened bending part section 112, which after reaching the highest point of the ramp 201, as in FIG. 15 shown, the locking lug 12 can snap back into the recess 13 of the first engagement portion 20.
  • the hook element 15 strikes the second sealing ring 162 and thus seals the annular gap formed there. Due to the shape of the locking lug 12 and the abrupt drop of the locking lug 12, the two housings 1 and 2 are locked by the finger member 11 into each other.
  • the stop surface 121 of the locking lug 12 (s. FIG. 19 ) abuts the abutment surface 202 of the ramp 201.
  • FIG. 16 shows a top view of the two latched housing 1 and 2.
  • FIG. 16 also defines the two cutting lines K and L.
  • FIG. 17 shows the KK section according to Fig. 16 the nested and latched housing 1 and 2.
  • FIG. 18 shows the LL section according to FIG. 16 the mated and latched housing 1, 2.
  • the FIGS. 17 and 18 moreover, show how the bushing element 3 and the pin element 4 are positioned interlocking and thus the contact between the two elements is made as desired.
  • FIG. 19 and FIG. 20 show, as by actuation of the coupling sleeve 14, that is, by displacement of the coupling sleeve 14 from the first position to Fig. 19 in the second position Fig. 20 along the central axis M, the latching between the two housings 1, 2 can be canceled.
  • the bending section 110 extends slightly radially outward towards the distal end. Furthermore, it can be seen that the radial material thickness of the bending section 110 increases in the distal direction, ie the bending section 110 becomes thicker. The increase in radial material thickness is continuous and is up to 20% to 300% of the initial radial material thickness of the bending portion 110.
  • the club-shaped bending portion 110 is rounded at its distal end. In the region of the distal end of the portion 110, the radially inwardly projecting nose 12 is attached.
  • the projection height of the nose 12 and the length along the M-axis of the nose 12 is about as large as the above-mentioned initial material thickness of the bending portion 110.
  • the aforementioned thickening of the bending portion 110 in the distal direction and the nose 12 then provide an inclined surface 120 , which is so large that the bending portion 110 clean from Hook element 15 contacted with the inclined surface 150 and can be moved. This improves the guidance and increases the stability during the plug-in process, which enables a high number of mating cycles or a long service life of the coupling.
  • a cover portion 152 of the sleeve 14 which forms a proximal end of the recess 151 and is in surface contact with the finger member 11, in the proximal direction of the housing first displaced, thereby releasing the entire bending portion 110, so that when deflecting the finger element 11 by the hook member 15 of the bending region in comparison to the deflection of the finger element 11 by driving on the ramp 201 (s. Fig. 14 ) extended.
  • the ramp 201 so only the bending part portion 112 is deformed in the deflection by the sleeve 14 of the entire bending portion 110th
  • Extending this length of the bending piece portion 112 to the bending portion 110 may generally be about 10% to 50%, more preferably about 15% to 25%, or 20% of the total length of the bending portion 110.
  • a locking element 19 may be provided, which serves to ensure that the coupling sleeve 14 located under spring pressure in the first position is not moved unintentionally into the second position.
  • the locking element 19 (only in FIGS. 17 and 18 shown) is a locking ring which is disposed proximally behind the coupling sleeve 14, wherein on the sleeve 102, a stop 1020 is provided (s. Figures 17 and 10 ).
  • the locking element 19 is arranged in the recess between the proximal end of the coupling sleeve 14 and the stop 1020. Since the locking element 19 substantially fills this recess, the coupling sleeve 14 is blocked when the locking element 19 is inserted.
  • the sleeve 14 is displaceable from the first position in the proximal direction to the second position.
