  • the plug part 1 of the second exemplary embodiment differs from that of the first exemplary embodiment by the retaining ring 10 used with the molded-on locking elements 6 and its mode of action. In the following, only the differences between the two variants of the connector parts 1 will be described.
  • the plug part 1 and the mating plug part 3 can be locked together by means of the locking elements 6 in a detachable manner according to the push-pull principle.
  • the plug part 1 has a locking mechanism according to the push-pull principle, which in the embodiment, a plurality of axially extending, radially deflectable locking elements 6, thesentriegelnd and each having a transversely thereto, radially inwardly projecting pawl 7 are formed, which in the figure 2 shown mating connector part side, outwardly open latch 8 is assigned.
  • the locking elements 6 are arranged opposite the latching traps 8 such that the latching pawls 7 do not engage in the latching traps 8 without external force.
  • the locking elements 6 of the plug part 1 are actuated by means of the axially displaceable unlocking sleeve 9 carried by the plug part 1 via the locking sleeve 22 mechanically coupled to the locking sleeve 22 in such a way that the latching pawls 7 of the plug part 1 are radially outwardly inclined and the catch pawls 8 of the mating connector part 3 in the movement of the unlocking sleeve 9 in the insertion direction of the plug part 1 engage.
  • the locking pawl 7 has a rear sliding ramp 14 arranged in the direction of insertion of the plug part 1 at the rear, and the latching latch 8 has an associated rear counter-sliding ramp 1 6 arranged in the insertion direction of the plug part 1 on the inside on, the play the part 1 and the mating connector part 3 when locking by means of a radially inwardly acting spring force component free of play.
  • the detent pawl 7 also has a front sliding ramp 13 arranged in the plug-in direction of the plug-in part 1 and the latching latch 8 has an associated rear counter-slide ramp 15 arranged rearwardly in the plug-in direction of the plug part 1 and deflecting the locking element 6 radially outwards for locking.
  • the corresponding counter slide ramps 15, 16 are shown in FIG. The mode of action can be seen in FIGS. 6 and 7 and will be described in more detail below in connection with these figures.
  • the locking elements 6 have on the outside each an actuating cam 26 without, which is formed without unlocking 18.
  • a release hook is not required in this case, the locking elements 6 aresentriegelnd formed. Consequently, in this exemplary embodiment, the unlocking sleeve 9 also has no driver hooks 19 for the missing unlocking hooks 18 on the inside.
  • the latch 7 is latched by means of the locking sleeve 22 into the latch trap 8 and is securable there when the latch 7 at least partially overlaps the latch 8, and automatically latches out of the latch 8 as soon as the locking sleeve 22 with the in the radial direction outside inclined sleeve section 24 does not act on the actuating cam 26, the locking element 6.
  • the spring force which acts on the securing sleeve 22 in the plug-in direction of the plug part 1 is greater than the radial spring force of the locking elements 6 integrally formed on the retaining ring 10. In particular, it is dimensioned considerably larger, dimensioned in this way.
  • the retaining ring 10, on which the locking elements 6 are arranged axially projecting in the direction of insertion, is in the illustrated embodiment of a made of resilient metal material, so that the locking elements 6 are resilient.

Abstract

L'invention concerne un connecteur circulaire électrique (2) comprenant une partie de connexion (1) et une partie de connexion complémentaire (3), qui peuvent être verrouillées ensemble de manière libérable au moyen d'un mécanisme de verrouillage pousser-tirer par l'intermédiaire d'au moins un élément de verrouillage (6) s'étendant axialement et pouvant être dévié radialement. Ledit élément de verrouillage comporte un cliquet d'arrêt (7) faisant saillie vers l'intérieur, auquel un loquet d'arrêt (8) ouvert radialement vers l'extérieur est associé sur la partie de connexion complémentaire (3). L'élément de verrouillage (6) est formé sur une bague de retenue (10), qui est montée de manière immobile sur la partie de connexion (1) entre le manchon de déverrouillage (9) et une zone de connexion (11) avant, de forme cylindrique creuse, de la partie de connexion (1), et ledit élément regroupe sans jeu la partie de connexion (1) et la partie de connexion complémentaire (3), au moyen d'une composante de force élastique agissant vers l'intérieur dans la direction radiale. Selon l'invention, un manchon de blocage (22) pour l'élément de verrouillage (6) est mobile axialement avec le manchon de déverrouillage (9). Ledit manchon de blocage expose l'élément de verrouillage (6) à une force élastique radialement vers l'intérieur au moyen d'un ressort de pression (23) en forme de spirale, et est disposé entre la bague de retenue (10) et le manchon de déverrouillage (9).
