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 in the usual way and inserted into one another.
  • the locking device has two locking parts. the two opposite and perpendicular to the contact plane. extending sides of the second connector part are stored.
  • 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. to create a connector with a locking device. which enables a safe and particularly easy loosening and joining of the connector parts even with a connector that 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. than due to the leverage 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 assemble or detach the plug parts.
  • the pivotable mounting 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 advantageously acts in the same direction as the force which is required to detach the second plug part from the first plug part.
  • DE-A-28 49 077 discloses a connector which has a first connector part and a second connector part which is pivotally held thereon, the second connector part having a locking part on its side opposite the pivotable mounting, but this locking part consists only of a locking lug which engages in an opening of a leaf spring held on the first plug part; the locking part is therefore neither rotatably mounted nor does it have a grip strip for manual unlocking.
  • the mechanical tension for secure locking is applied in a simple manner in one embodiment of the connector. if the bent part is a spiral spring.
  • 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.
  • On the holding frame 3, an axis 7 is attached outside the area of the contact elements, which 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 connector 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 extending transversely to the latter engages on the holding member 13a. on which a grip bar 15 is also held transversely to the holding member 13a.
  • a bent part 17 is connected in one piece to the locking part 12.
  • This bent part 17 is guided obliquely from the grip bar 15 to the shaft 10 and shaped so that it exerts a mechanical tension 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 power transmission from the handle 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 is therefore removable.
  • the two connector parts it is necessary. first to pivotally connect the two plug parts to one another via the hook 8 and the axis 7 and then to pivot the second plug part 2 in the direction of the first plug part 1, the locking part automatically snapping into the first plug part 1 via the barb 14.
