Definitions

  • the invention relates to a plug connector with a first plug part and a second plug part that can be plugged onto this plug, and with a locking device with a locking part that is rotatably mounted about an axis of rotation on the second plug part and in the locking position with a second plug part plugged in with a holding member in barbs held at a distance from the axis of rotation engages in a corresponding recess on the first plug part and has a grip strip on a holding part for unlocking the plug parts against the action of a bent part supported on the second plug part.
  • the connector parts with their contact elements are moved towards one another and inserted into one another in the usual way.
  • the locking device has two locking parts which are mounted on two opposite sides of the second plug part which extend perpendicular to the contact plane.
  • the holding members with their barbs form a two-armed lever together with the handle strips on the holding parts, so that they can be unlocked by exerting pressure on the handle strips in the direction of the respective sides of the second plug part.
  • the second connector part can then be pulled off the first connector part perpendicularly to the contact plane by applying an additional tensile force.
  • the invention is therefore based on the object of providing a plug connector with a locking device which enables safe and particularly simple detachment and assembly of the plug parts even in the case of a connector which is difficult to access.
  • the second connector part is pivotally mounted on the first connector part outside the area of the contact elements of the connector parts; the locking part is mounted on the side of the second plug part opposite the bearing point, and the holding part engages in the region of the barb on the holding member and extends transversely to the latter.
  • the device according to the invention is advantageous in that, due to the lever action in the pivotable mounting of the second plug part, only a small force has to be applied to the end of the second plug part having the locking part in order to join the plug parts or to detach them from one another.
  • the pivoting storage can be designed so that the second plug part can be unhooked or re-hooked in a predetermined rotational position.
  • the force which must be applied to the handle bar of the locking part for unlocking is effective in the same direction as the force which is required to detach the second plug part from the first plug part.
  • the mechanical tension for secure locking is applied in a simple manner if the bent part is a spiral spring.
  • An advantageous construction of the locking device according to the invention in particular with regard to the application of the force for unlocking and removing the second plug part, results when the second plug part has a shaft on its side opposite the bearing point, the axis of rotation of the locking part in the area of the first plug part facing Side of the shaft is arranged and the bent part between the handle bar of the locking part and the shaft of the second connector part and can be bent to a predetermined extent.
  • the barb and the area of the recess on the first plug part are chamfered in such a way that the barbs snap into the recess when the plug parts are joined together.
  • Another embodiment of the locking device in which the locking part and the bent part are formed in one piece from a material that is elastic depending on the material thickness, is designed in a particularly advantageous manner with a bent part that is guided obliquely away from the handle and with its free end on Shaft of the second connector part rests.
  • the free end of the rod is expediently completely rounded.
  • the locking and the bent part are advantageously made of a particularly temperature and aging-resistant plastic, which ensures a permanent, safe function of the locking device.
  • FIG. 1 shows a plug connector with a first plug part 1 and a second plug part 2.
  • the first plug part 1 consists of a holding frame 3, which is fastened to a housing of an electrical device 5 by means of pins 4, and a part 6, which contains contact elements for the plug connection.
  • An axis 7 is attached to the holding frame 3 outside the area of the contact elements and is partially encompassed by a hook 8 of the second plug part 2 and forms a bearing point for the pivotable mounting of the second plug part 2 on the first plug part 1.
  • the second plug part 2 has contact elements 9 which engage in the corresponding contact elements in part 6 of the first plug part 1.
  • the second plug part 2 has a shaft 10 on its side opposite the bearing point. On the side of the shaft 10 facing the first plug part 1, an axis of rotation 11 is held on the second plug part 2, on which a locking part 12 is rotatably held as a component of the locking device.
  • the locking part 12 has a holding member 13a, on which a barb 14 is held at a distance from the axis of rotation 11.
  • the barb 14 engages in the locked state in a corresponding recess 16 of the first plug part 1 or the holding frame 3.
  • the barb 14 and the holding frame 3 in the region of the recess 16 are chamfered in such a way that when the barb 14 is locked, it can snap in without additional actuation of the locking part 12.
  • a holding part 13b which extends transversely to the holding element 13b and on which a grip strip 15 is also held transversely to the holding element 13a, engages on the holding element 13a.
  • a bent part 17 is integrally connected to the locking part 12.
  • This bent part 17 is guided obliquely from the handle bar 15 to the shaft 10 and shaped so that it is a mecha African tension exerts on the locking part 12, which holds the barb 14 in the locking position of the locking part 12 in the recess 16.
  • the free end 18 of the bent part 17 is rounded so that the bent part 17 cannot jam even when the shaft 10 is moved.
  • On the bent part 17 there is an extension 19 which is in contact with the locking part 12 when the maximum deflection of the bent part 17 is reached.
  • the locking part 12 and the bent part 17 are preferably made of a temperature and aging resistant plastic. It is also conceivable that another resilient element, e.g. B. a coil spring, with which a corresponding force can be exerted on the locking part 12.
  • the locking part 12 shows the locking part 12 in a state after the unlocking.
  • the barb 14 was pressed out of the recess 16 so that the second plug part 2 can then be pivoted about the axis 7 (see FIG. 1).
  • the bent part 17 is bent so far here that the shoulder 19 abuts the locking part 12 and thus a direct transmission of force from the grip bar 15 of the locking part 12 to the shaft 10 of the second connector part 2 is possible.
  • the unlocked plug part 2 has already been partially released from the first plug part 1, so that the second plug part 2 can be pivoted about the axis 7 (cf. FIG. 1) by a force on the handle bar 15 so that it can be unhooked on the hook 8 and thus removed.
  • the two connector parts it is necessary to first pivotally connect the two connector parts to one another via the hook 8 and the axis 7 and then the second connector part 2 in the direction of the to pivot the first plug part 1, the locking part automatically snapping into the first plug part 1 via the barb 14.
