Definitions

  • the invention relates to an electrical connector with the features of The preamble of claim 1.
  • a locking bracket known from DE 196 33 827 C1 acts for a connector with its side or bottom edge the corresponding Locking projection immediately.
  • this connector between a plug housing and an add-on housing is used for generation a secure hold of the locking bracket in the locking position required Pressurization from one provided between the housings Rubber seal taken over.
  • the invention has for its object an electrical connector to simplify the type mentioned at the outset in terms of construction and operation.
  • the connector parts includes a lower part and one on Lower part plug-on upper part preferably having electrical connectors two pivoted on both sides of one of the connector parts, with the other connector part lockable in the manner of a sash and each through a common handle part to a uniform locking bracket interconnected locking leg.
  • Their swivel levels are roughly aligned parallel in the direction of insertion of the connector.
  • the one-armed type Lever effective locking legs are approximately parallel to each other Flat parts formed and reach behind with their unsupported lever or Locking ends each extending transversely to the direction of insertion and thus locking projection protruding from the other connector part into the swivel planes, in particular a locking pin.
  • In the rear grip position are the locking legs by spring pressure system or spring pressure secured by one piece with the respective locking leg, angled spring cantilevers are produced from the surface extension thereof, the spring arm in the locking position the locking projection embraces.
  • the locking limbs act on the respective locking projection immediately with a side edge.
  • Each locking leg of the locking bracket acts directly on the connector on the locking projection of the other connector part, and that parallel to the one that also acts directly on the locking projection, spring pressure coupled with it.
  • the safety of rest is advantageously achieved by a trough the spring arm increases and can by a half the diameter of Locking projection, in particular of the pin diameter, approximately corresponding Trough radius can be improved.
  • a connecting web between a locking leg and its spring arm with only one holding end of the arm connected.
  • the spring arm then stands approximately in this direction from this holding end parallel to the surface extension of the locking leg.
  • the appropriate length of the type about one Leaf spring reboundable lever arm of the spring arm is advantageous by Shape design provided.
  • the fact that the spring arm counter the direction of the grip of its locking leg protrudes from the connecting web, on the one hand, the functional reliability of the locking is favored. On the other hand is the spring arm during the locking movement against its functionality adverse deformation protected.
  • the locking bracket or its locking legs are preferably made of sheet steel, the Material self-suspension behavior for the functionality of the spring arm is sufficient.
  • An important aspect for the user-friendliness of the connector is the position fixing of the locking bracket in the open position.
  • This aspect relates to the pivoting position of the locking bracket relative to the associated connector part and is therefore fundamentally independent of the structural design of the areas of the locking bracket and the associated connector part to be locked together.
  • a position fixation of the locking bracket in the open state by means of a locking bracket is advantageous in the event that both connector parts are to be plugged together "and then when a locking bracket prevents the connector from being plugged together due to its pivoting position. This is the case if the locking bracket (s) fall on the contact area of their connector part. Then they have to be swung away again from the contact area in order to avoid unhindered To solve this problem, a locking bracket serves to solve this problem in the unlocked position of a locking bracket which inhibits its pivoting movement relative to the associated connector part.
  • a locking inhibition at both ends of the Swivel range of the locking bracket i.e. in locking and unlocking positions intended.
  • the connector contains the lower part 1 and the connector parts thereon attached upper part 2.
  • the arranged within the two connector parts 1,2 Contact parts are of no importance for the invention and are therefore not shown.
  • a locking bracket 3 is pivotally mounted on both sides.
  • the Locking bracket 3 each have two on both sides of the lower part 1 pivotable stored locking leg 4 on the by a common handle part 5th to the U-shaped, one-piece locking bracket 3 with each other are connected.
  • the pivot planes of the locking legs 4 are approximately parallel to the central longitudinal plane 7 of the connector running in the direction of insertion 6.
  • the swivel planes are therefore parallel to the image plane in FIGS. 1, 3 and 6 and perpendicular to the image plane of FIGS. 2, 4 and 5.
  • the effective in the manner of one-armed lever locking legs 4 are each pivotally mounted about pivot axes 8 fixedly connected to the lower part 1.
  • the pivot axes 8 are formed by stub axles 9, which on both sides of the Flanks 10 of the lower part 1 protrude.
  • the locking legs 4 are with its inner end pivotable on the stub axles or journals 9 of the Lower part 1 stored.
  • One end of the bearing 11 and the other locking end 12 are the free ends of the legs of an angular shape with the angular apex (Side view in Fig. 1 and 3) as a handle part 5. This angle shape can also be used as V-shape.
  • each locking leg 4 is effective a one-armed lever, which by its locking end 12 with the formed by a locking pin 13 locking projection of the lower part 1 interacts in the manner of a taster.
  • Fig. 1, right and Fig. 3 acts on the locking leg 4 with the inner Side edge 14 of its V-leg associated with the locking end 12 immediately the circumference of the locking pin 13 while in the open position the locking pin 13 for unhindered release of the upper part 2 releases from the lower part 1 (Fig. 1. left).
  • the spring arm 15 acts in the locked position with its facing surface Locking pin 13 from above, thereby forming a clamp. It can be a friction spring acting like a leaf spring. In the embodiment is this is a form lock in that the spring arm 15 on the locking pin 13 facing side is empty. If here is the boom is referred to as a spring boom 15, it does not have to mean that it is in the latched position additionally exert a spring action on the locking pin 13 got to.
  • Form-locking effect formed is in the corresponding pivot position of the locking leg 4 or the locking bracket 3 opposite a positive connection the locking pin 13 is present, which cause the inhibitory effect is. Only when swiveling back with the appropriate effort of the locking bracket 3 or its locking leg 4 the locking position (Fig. 1, right) in the open position (Fig. 1, left) it requires a certain spring property of the boom 15 compared to the Locking legs 4 to perform the desired locking function.
  • the spring arm 15 is by one in the direction of the pivot axis 8 of his Holding end 18 inwardly connecting web 17 with the locking leg 4 connected in one piece in the area of the locking end 12. From the holding end 18 in the area of the connecting web 17 is the boom 15 in the direction approximately parallel to the surface extension of the locking leg 4 from, namely against the rear grip direction 19. On the Connector parts 1,2 acting tensile forces are not on the spring arm 15, but over the bottom or side edge 14 of the locking leg 4 - and over the pin-shaped locking projection 13 - in the respective Locking bracket 3 initiated.
  • the unlocked position of the locking bracket 3 or its Locking leg 4 is one whose pivoting mobility relative to the Swiveling bottom part 1 locking catch effective.
  • the effectiveness extends to the bearing area between the locking leg 4 and the bearing journal 9 of the lower part 1 in it.
  • a bearing sleeve 20 is rotatably inserted.
  • the bearing sleeve 20 covers the end face 21 of the journal or stub axle 9 with its cap 22. It surrounds the jacket of the stub axle 9 with its inner cylinder jacket 23.
  • the locking clamp is between the cap 22 and the front end 21 of the journal 9 effective.
  • the bearing sleeve 20 is formed by a plastic part, which by a positive locking 24 with the locking leg 4 is rotatably connected.
  • the longitudinal rib 24 extends radially expedient over the entire diameter of the journal 9. It has the cross-sectional shape of a wedge, the Flanks converge in the direction of the journal 9 and thus run-up bevels form.
  • the plastic material of the closure caps 22 is resilient, which is sufficient for the generation, towards the end face 21 of the bearing pin 9 oriented spring pressure is sufficient. This spring action serves to engage the longitudinal rib 25 in a extending over the end face 21 Locking notch 26 when the locking leg 4 is in one Rotary position on the stub axle 9 is that the longitudinal rib 25 in an angular Overlap with the notch 26 is.
  • the notch 26 extends expediently over the entire diameter of the journal 9. Your Angular position is selected so that it is in the open position of the locking bracket 3 corresponds to the angular position of the longitudinal rib 25.
  • a second notch 27 on the end face 21 of the journal 9 arranged in a different angular position, that of the locking position of the locking bracket 3 or the locking leg 4 is assigned.
  • the Notch 27 thereby ensures in the locking position together with the longitudinal rib 25 for a second locking inhibition in addition to the interaction of the spring arm 15 formed with the locking pin 13 locking bracket.
  • the locking pin 13 on the upper part 2 and the bearing pin 9 on the lower part 1 are preferably identical in shape and arrangement. This allows the Locking bracket 3 can optionally be stored on the upper part 2. Then it is Bearing pin 9 on the lower part 1 as a locking pin for the locking bracket 3 effective.
