  • the latching means and / or the recess and / or the taper is / are then preferably arranged in the plug-in area of the circular connector in such a way that, in an inserted state, a complementary latching means of a complementary plug-in element engages the latching means of the circular connector.
  • the at least one locking means can be brought by an associated guide element to assume the locked position and / or disengaged position and thereby enable a connection and / or disconnection of the circular connector and the complementary plug element.
  • the guide element When using a latching hook as a latching means, the guide element preferably has a guide rail along the longitudinal axis of the circular connector.
  • the guide element can be displaceable relative to the latching hook. With this relative movement parallel to the longitudinal axis, the hook area can be moved in the radial direction towards the longitudinal axis or away from the longitudinal axis.
  • the at least one guide element is preferably connected by a hollow cylinder parallel to the longitudinal axis of the circular connector.
  • the guide element also preferably has a ring and / or stop ring and / or unlocking ring which is firmly connected to the hollow cylinder.
  • the ring is used for better operability by the user.
  • the ring can also serve as a stop for the complementary plug-in element.
  • the ring preferably also has a spring system which fixes the locking means body in a locking position without the action of external force.
  • a force acting on the ring opposite to the insertion direction causes a movement of the ring and the hollow cylinder along the longitudinal axis relative to the locking means and thereby a disengaged position of the locking means. In the disengaged position, the connection between the circular connector and the complementary plug-in element can be released.
  • the guide element can preferably be designed as a hollow cylinder along the longitudinal axis of the circular connector, the recess being arranged in the hollow cylinder wall.
  • the guide element can, however, also be arranged as a movable hollow cylinder in accordance with the arrangement for a latching hook.
  • the hollow cylinder as a guide element of the locking means body is moved along the longitudinal axis of the circular connector and causes the locking means of the complementary plug-in element to engage and / or disengage.
  • the entire locking means body is thus always designed approximately as a hollow cylinder, which is ideally arranged concentrically around the longitudinal axis and thus ideally also concentrically around the connection element. In the case of a real circular connector, however, an exactly concentric alignment of the locking means body often cannot be sufficiently ensured in the manufacturing process.
  • the locking means body can also be formed for the entire area of its hollow cylinder from a material which provides electrical shielding of the contact elements in the connection element.
  • the hollow cylinder of the connection element and the hollow cylinder of the locking means body can preferably form a common hollow cylinder.
  • a cavity is arranged between the hollow cylinder of the connection element and the hollow cylinder of the locking means body.
  • the two hollow cylinders are thus spaced apart from one another and are not firmly connected to one another in any area.
  • the difference between the two radii that is to say the distance between the two hollow cylinders in the radial direction with respect to the longitudinal axis, is preferably at least 0.2 mm and particularly preferably at least 0.4 mm. If the connection element does not form a hollow cylinder in the insertion area, the hollow cylinder of the latching means body is spaced apart from the at least one contact element of the connection element.
  • the solid cylinder of the connection element in the plug-in area is spaced from the hollow cylinder of the locking element body so far that the common hollow cylinder of the connection element and the locking element body of the male circular connector can engage in the inserted state.
  • the connection of the round plug-in connector and the complementary plug-in element can be achieved without time-consuming screwing, that is, very quickly, in particular by simply pressing. Accordingly, the connection can also be released again very quickly, in particular by simply pulling it.
  • the circular connector can thus be used as a so-called “push-pull” connector.
  • a shield element which is designed as a hollow cylinder, is also arranged around the connection element in some areas.
  • the shield element extends along the longitudinal axis of the circular connector at least from the cross section on the longitudinal axis at which the latching means body ends, to beyond the contact element holding area of the connection element.
  • the shield element also extends along the longitudinal axis in such a way that electrical shielding of the cable area, which is not covered by the braided shield due to the contact with the circular connector, is completely covered.
  • the shield element can also overlap in some areas along the longitudinal axis with the hollow cylinder of the locking means body. However, the shield element does not surround the connection element in the insertion area.
  • the shield element is connected to the connection element in a fixed and / or dimensionally stable manner. This means that the outer radius of the solid cylinder of the connection element rests against the inner radius of the hollow cylinder of the shield element in the contact element holding area or in the cable contact area.
  • the hollow cylinder of the shield element cannot be moved relative to the connection element, neither along the longitudinal axis, nor in the radial direction to the longitudinal axis, nor in the circumferential direction.
  • the connection element and the shield element form a rigid unit.
  • the shielding element and latching body are movably coupled to one another, that is to say are not rigidly connected to one another. Coupled here means that this coupling cannot be released by external forces without the circular connector being improperly deformed.
  • the movable coupling enables a relative movement of the locking means body with respect to the shield element and the connection element.
  • the locking means body can be movable in all spatial directions, for example along the longitudinal axis, radially and rotatably in the direction of the circumference.
  • the latching body is mounted and / or arranged on the circular connector in such a way that it has a play in movement to the rest of the circular connector.
  • the movable coupling between the shield element and the locking element body allows the hollow cylinder of the locking element body to move relative to the hollow cylinder of the connection element and penetrate at least partially into the cavity between the hollow cylinder of the connection element and the locking element body.
  • the movable coupling between the shield element and the locking element body allows the hollow cylinder of the locking element body to move relative to the solid cylinder of the connection element and at least partially penetrate the cavity between the solid cylinder of the connection element and the locking element body.
  • This movable coupling between the shield element and the locking element body has the advantage over a conventional, rigid connection that, in the case of a full cylinder and / or hollow cylinder of the circular connector and / or the complementary plug element that is not exactly concentric, an additional spatial tolerance is available for the insertion process to bring the respective complementary connection elements and locking means body into engagement.
  • the movable coupling thus offers additional play so that in the case of a male circular connector the common hollow cylinder of the connecting element and the locking means body can connect and / or be located with the solid cylinder and the hollow cylinder of the complementary plug-in element in the plug-in area.
  • the locking means body and the screen element can be moved by a locking ring coupled to each other.
  • the screen element is located in sections within the locking means body and the hollow cylinders of the locking means body and the screen element preferably each have a groove arranged opposite one another in the radial direction.
  • the two grooves are formed for at least part of the circumference of the hollow cylinder, preferably for the entire circumference of the hollow cylinder.
  • the radial extension of at least one of the two grooves is at least as large as the radial extension of the locking ring so that the locking ring can be forced into this groove during assembly.
  • the relaxed locking ring and / or the at least partially relaxed locking ring then has a smaller inner radius than the outer radius of the hollow cylinder of the radially inner element, for example the shield element, around the groove.
  • the relaxed locking ring and / or the at least partially relaxed locking ring has a larger outer radius than the inner radius of the hollow cylinder of the radially outer element, for example the locking means body, around its groove.
  • the extent of the two grooves parallel to the longitudinal axis of the circular connector is in each case at least as large as the extent of the securing ring parallel to the longitudinal axis of the circular connector.
  • the locking means body can be moved along the longitudinal axis, radially and in the direction of the circumference relative to the shield element and the coupling of the shield element and the locking means body cannot be released by external forces without the circular connector being improperly deformed.
  • the securing ring can enable at least a form-fitting attachment of the locking means body to the circular connector.
  • a seal is arranged between the shield element and the locking means body.
  • the seal is preferably made of an elastic material and can be arranged around the screen element.
  • the seal allows the locking means body to move relative to the longitudinal axis in the direction of the shield element. Due to the relative movement of the locking means body, the seal is elastically deformed and generates a counterforce in the insertion direction. As a result, without the action of external force, the seal relaxes again and moves the locking means body relatively again back in the direction of insertion. In interaction with the spring system of the locking means body, the seal can fix the locking means body in a locking position.
  • the shield element is arranged in some areas within an injection-molded body and is firmly connected to the injection-molded body.
  • the injection-molded body is designed to arrange a cable, which is electrically connected to the connection element, in some areas within the injection-molded body and to connect it firmly to the shielding element.
  • the solid connection of the injection molded body, shield element and cable creates a stable area of the circular connector that can only be deformed by the user through improperly high external forces.
  • the latching means body is designed to be movable at least 0.2 mm relative to the connection element due to the movable coupling to one another to the shield element; and / or the latching means body is designed to be movable at least 0.4 mm relative to the connection element due to the movable coupling to the screen element.
  • the locking means body is preferably movable in the radial direction at least 0.2 mm relative to the connection element and / or at least 0.4 mm relative to the connection element.
  • the hollow cylinder and / or the solid cylinder of the connection element and the hollow cylinder of the locking means body can be moved relative to one another less than 0.2 mm, since the hollow cylinder of the locking means is designed as a hollow cylinder together with the shield element and this hollow cylinder is firmly arranged in an injection molded body.
  • Conventional circular connectors often deviate from the concentric arrangement, which are at least 0.2 mm. Due to the rigid arrangement in an injection-molded body, insertion of such a round plug connector into the complementary plug-in element is only possible with great effort, and there is also the risk of the round plug-in connector or the complementary one Damage the plug element.
  • the movable coupling to one another can also have a limitation of the maximum relative movement of the locking means body to the screen element.
  • This limitation preferably enables a relative movement of a maximum of 1 mm, more preferably a relative movement of a maximum of 0.7 mm and particularly preferably a maximum of 0.5 mm along the longitudinal axis and / or in the radial direction.
  • the minimum mobility and the maximum mobility can be designed differently along the longitudinal axis, radially and in the direction of the circumference.
  • the locking means body has a stop ring, at least one locking means and in each case a guide element for the at least one locking means.
  • the stop ring is connected to the at least one guide element and is designed to be movable relative to the latching means along an insertion direction.
  • the latching means is elastic and / or has a spring element.
  • Another independent aspect for solving the problem relates to a plug-in system with a circular connector according to one of the preceding aspects and embodiments, and a complementary plug-in element, the complementary plug-in element having a complementary connection element that can be connected to the connection element of the circular connector.

  • the complementary plug-in element and / or the plug-in region of the complementary plug-in element preferably has at least two complementary latching means and particularly preferably three complementary latching means.
  • the complementary plug-in element preferably has a spring element body in which the at least one latching means and / or spring element is formed.
