Definitions

  • the invention relates to a device for locking a connector housing with a mating connector housing, which are mutually attachable with mutually complementary openings - preferably sealing against dirt and moisture and for producing an electrical shield - the connector housing for receiving one with a plurality of plug contacts which are connectable with electrical conductors, the plug insert is designed, and the mating connector housing is designed to receive a mating connector insert provided with a plurality of complementary plug contacts which can be connected to electrical conductors, and one of the two housings - in particular on the plug housing an axis pivotable on two bearing journals U-shaped locking bracket is arranged, the parallel arms lying on both sides along the housing and are firmly connected at their ends via a cross bracket and the respective s have a locking curve with a recess, which may be recessed, in the swivel direction for locking, and two other locking pins are provided on the other of the two housings - in particular on the mating connector housing - which are parallel to the bearing pins when the two housings are properly seated against
  • the invention relates to a connector combination consisting of a connector housing and mating connector housing with a Device for locking the above-mentioned type.
  • the housings mentioned are generally, on the one hand, a plug housing in which a plug insert is inserted, for example with a plurality of pin contacts, and which has a cable bushing through which a conductor cable leading out of the housing is located Sealing is led out, and on the other hand around a so-called add-on housing, which receives a plug insert with mating contacts, in particular socket contacts, and which enables a flange surface for attachment to parts of a control cabinet, for example in a plate or on corresponding holding rails, the housing in particular being the same on both sides Has opening cross-section.
  • the device is also suitable in the same way for locking connector housings and mating connector housings, both of which are provided with cable bushings for connection to conductor cables.
  • a known type for the permanent and reliable connection of housings of the type mentioned is the mutual screwing.
  • tabs or eyes are provided on the housings, with a through hole being formed in one case and a threaded bore in the other case, so that the housing parts can be screwed together.
  • the increased assembly effort is disadvantageous here, which is particularly disadvantageous when plug connections have to be made and loosened or replaced regularly. This can then easily damage the threads, so that the corresponding housing with the threaded holes is unusable.
  • the O-ring seal is formed in circumferential surfaces with respect to the mutual insertion direction, so that locking problems can arise.
  • the known locking device is unsuitable if the plug connections produced are exposed to severe impacts and / or regular strong vibrations during operation.
  • the acceleration forces occurring can be so great that they exceed the force required for the release of the locking bracket, so that the securing of the plug connection by devices of the known type must be regarded as inadequate for these applications.
  • An example of this is the use of plug connections of the type mentioned in the railway sector, ie on rail vehicles.
  • a resilient locking device is arranged on the housing carrying the locking bracket, which interacts with the locking bracket in its locked position with the locking pin of the other housing and that only after releasing the resilient locking device, the locking bracket can be pivoted away from the locking position.
  • the locking bracket ensures that the connection is secured can advantageously not be burdened by the forces acting between the housing halves and possibly released.
  • a positive locking by the locking device which can be designed so that it engages automatically when closing the locking bracket in the locking position and can only be solved by actuating a pawl or the like to be released by hand.
  • the locking device is in particular to be arranged at the extreme end of the arms of the locking bracket in order to be able to exert a large retaining torque on the locking bracket with small holding forces or relatively light design of the latching elements used.
  • the locking device is formed on the housing carrying the locking bracket. This has again the advantage that tolerances of the housing parts, the state of wear of the seal and the like have no influence on the proper functioning of the locking device. This can be set exactly on the attached locking bracket or the correct function can be checked on the corresponding housing part alone.
  • the locking device comprises a bearing block which can be screwed onto one of the housings and in which a pawl provided with locking and holding elements for the locking bracket is pivotably mounted against the force of spring means.
  • the locking device comprises a bearing block which can be screwed onto one of the housings and in which claws or bolts provided with locking and holding elements for the locking bracket are rotatably or displaceably mounted against the force of spring means.
  • the locking device comprises a resilient locking element which can be screwed onto one of the housings and of which a part provided with locking and holding elements for the locking bracket can be deflected elastically.
  • housings usually shown as castings can be used in a standard design, only threaded holes for the mounting of the bearing block of the locking device or the elastic locking device itself on the housings must be additionally carried out.
  • the locking and holding elements for the locking bracket can interact with locking and retaining notches in the arms of the locking bracket, as will be explained later using the exemplary embodiment.
  • locking clips of the known type without any change or adaptation, provided that the locking and holding elements of the locking device are designed so that they engage behind parts of the locking bracket after reaching the locking position.
  • a particularly inexpensive and practical embodiment which enables the locking device to be unlocked and the locking bracket to be unlocked in one-hand operation, is that the crossbar of the locking bracket is designed as a pull handle and that the locking means comprises a pawl parallel to it, designed as a pushbutton, starting from from the locked position, the tensile loading of the crossbar and the pressurization of the pawl in the sense of unlocking require approximately the same force.
  • the crossbar and pawl are to be offset from one another in such a way that a closing movement of the hand initiates the unlocking process, that is to say, for example, when the pawl is actuated the thumb, the fingers can be supported on the crossbar of the locking bracket.
  • a single device of the type according to the invention is preferably used, the bearing pins of the locking bracket and the locking pins for the locking bracket each having to be arranged in the central plane through the shorter axis of the housing, so that symmetrical force relationships occur the plugged together interlocked connector combination result d. H. in particular that the seals are loaded evenly.
  • each of the locking brackets is to be provided with a locking device according to the invention.
  • FIG 1 a side view of a connector housing 11 and an attachment housing 12 can be seen, which are connected to one another in the intended assignment.
