- Each locking portion 35 opposite to the insertion direction 19 adjacent the locking ring 15 has a release recess 37th on, located in the region of the respective associated locking head 29 of the locking ring 15 extends along the circumference of the locking ring 13.
- Ends of each release recess 37 each protrude a positive control rib 39 in the insertion direction 19 in the release recess 37 inside (see Fig. 5).
- the positive control ribs 39 have a respect the insertion direction 19 in the direction of the center of the locking ring 13 inclined forced-control end 41.
- the locking ring 13 also has on its in the insertion direction 19th pointing bottom 3 radially outward attachment hooks 43. These each protrude into one on the inner peripheral surface of the base housing 11 formed axial sliding groove 45 in the opposite direction of insertion 19 is limited by a fastening shoulder 47. Farther the locking ring 13 is radially on its inner peripheral surface inwardly offset insertion stops 48.
- a coil spring 49 is arranged, in the insertion direction 19 at the bottom of the base housing 11 and opposite to the insertion 19 abuts against the underside of the locking ring 13.
- FIG. 1 part of a mounting plate 51 is shown in FIG. 1, in which the base housing 11 is inserted.
- FIGS. 2 to 4 show the electrical connector according to FIG. 1 without Basic housing 11 and coil spring 49 and without mounting plate 51 in different positions of the locking ring 13, the locking ring 15th and the socket 17 relative to each other, as explained below becomes.
- Figs. 5 and 6 also show the electrical connector of Fig. 1 without base housing 11 and coil spring 49 in different relative positions.
- an electrical contact insert 53 shown within the contact portion 23 of the socket 17.
- the base housing 11 is opposite to the insertion direction 19 in an opening inserted within the mounting plate 51 and there fixed by means of a holding mechanism, not shown.
- the locking ring 13 in the insertion direction 19 in the Basic housing 11 is inserted until its attachment hooks 43 the respective Locking tab 47 of the base housing 11 engage behind.
- the coil spring 49 must in the insertion direction 19 are compressed, so that the inserted and hooked Locking ring 13 is biased and the locking position shown in Fig. 1 occupies.
- the socket 17 in Inserted 19 inserted into the base housing 11 until it is at the bottom of the basic housing 11 strikes.
- the Locking webs 25 of the socket 17 on the locking heads 29 of the locking ring 15 meet the Locking webs 25 of the socket 17 on the locking heads 29 of the locking ring 15, the in the locking position of the locking ring 13 shown in FIG with its radially outwardly directed back on the inner peripheral surface the respectively associated locking portion 35 of the locking ring 13 abut.
- the locking heads 29 give the pressure of the locking webs 25 and rotate in such a way that the socket 17 to the bottom the basic housing 11 can be moved. Due to a rebounding Rotate design of the locking heads 29 made of elastic plastic the locking heads 29 after passing the locking webs 25 back into their starting position.
- the plug-in sleeve 17 is thus as shown in FIGS. 1 and 5 with the basic housing 11 plugged.
- the socket 17 can no longer be unintentionally from the unit of the base housing 11, locking ring 15 and Loosen locking ring 13, as opposed to a movement of the plug sleeve 17 the insertion direction 19, the locking webs 25 abut the locking heads 29.
- the locking heads 29 can not oppose the above Turning described turn, since they already back to the Locking portions 35 of the locking ring 13 abut and thus against a reverse rotation are locked.
- the unlocking position of the locking ring shown in Fig. 3 is 13 reaches relative to the locking ring 15, in which the Freigabeaussparungen 37 of the locking ring 13 at the axial height of the locking heads 29 are located.
- the positive control ribs 39 for that the locking heads 29 with the locking clips 27 from their relaxed position 1 and 2 pressed radially outwardly in the release position are in which they are out of engagement with the second connector part 17.
- This active radial pressing out occurs in that the positive control ribs 39 with their forced control end faces 41 at the Base of the U-shape of the latching clip 27 abut (Figs. 2 and 6), and that at further axial movement of the positive control ribs 39 and the locking ring 13 in the insertion direction 19, the locking bracket 27 along the Forced control end faces 41 slide.
- the unlocking position shown in Fig. 3 is, the socket 17 of the unit of the base housing 11, locking ring 15 and locking ring 13 taken against the insertion direction 19 be as shown in Fig. 4.
- the locking webs 25 of the Plug 17, the locking heads 29 of the locking ring 15 without contact and thus pass unhindered, so that when pulling out the receptacle 17th no effort to overcome a locking connection between the Raststegen 25 and the locking heads 29 is required.
- Another advantage of the invention is that during insertion the plug-in sleeve 17 in the preassembled unit of the base housing 11, Locking ring 15 and locking ring 13 of the explained increased contact pressure for turning the locking heads 29 are not necessarily applied must, if at the same time pressed the locking ring 13 in the insertion direction 19 is and thus the locking bracket 27 actively moved radially outward become.
- the locking ring 15 is not necessarily - As shown in the figures - a separate from the base housing 11 component must be, but also be an integral part of the basic housing 11 can.
- a sealing ring be provided between the base housing 11 on the one hand and the Plug sleeve 17 and / or the locking ring 15 on the other hand.
