Definitions

  • the invention relates to an electrical connector, as it is described in detail, for. B. is known from DE-A-39 16 863.
  • a fork-shaped spring plate serves as a detent spring.
  • the middle prong of the fork is provided with an opening on its latching arm, FIG. 3.
  • the opening has a stop tab which can interact with a latching shoulder of a mating connector or device, compare FIG Release position can be pivoted or tilted.
  • a plug of a similar type is known from EP-A-0 351 083.
  • One end of a leaf spring forms a hook-shaped latching foot which can interact with corresponding latching means on the mating connector, see FIG. 6.
  • the known designs withstand the separating or tensile forces acting on the plug-in connector only until the freely movable locking section at the end of the detent spring is pushed out of its locking position to the outside, thereby releasing the detent cam or the like on the mating connector or device.
  • the invention is based on the endeavor to create an electrical connector of the type mentioned at the outset, in which a very high resistance to unlocking is opposed by external separating forces.
  • the invention provides that a stop surface is arranged on the housing, on which the detent spring is supported with a detent foot in the locking position, for example in the direction of the mating connector or the like. This ensures that the action of axial separating forces that want to release the electrical connector, the locking foot of the detent spring can not be pressed out into the release position. Consequently, extremely high separating forces can act on the mechanical locking of the plug without the detent spring losing its functionality.
  • the invention can be used both with detent springs made from spring sheet metal and from spring wire.
  • the stop spring of the catch spring which is displaceable or pivotable, is assigned a stop surface on the housing of the plug, which prevents the catch foot from moving outwards under the axial release force and thereby releasing the catch.
  • the arrangement and the course of the stop surface depends on the arrangement and shape of the detent spring.
  • the stop surface will generally run approximately perpendicular to the direction of insertion.
  • the stop surface can also deviate from this direction and z. B. extend up to about 45 ° to the direction of insertion.
  • the locking surface and the stop surface should run at least almost parallel to achieve an optimal effect. Deviations of approx. 15 ° appear to be tolerable.
  • the latching arm is Z-shaped and ends as a C-shaped latching foot which is bent downward toward the plug.
  • the locking foot is easy to slide and ensures a good contact with the mating connector or the like if it ends as a 180 ° bent hook and thus forms a large radius.
  • the plug is designed with three teeth, the outer tines are mounted on the housing as holding arms and the middle tine serves as a locking arm, it is advantageous if the holding arms and the locking arm are angled differently and the angle of the holding arms is greater is than the angle of the locking arm. A longer lever arm can thus be achieved on the latching arms and the spring properties are optimized.
  • the arms can be bent so that a shape similar to the number eight results in the side view.
  • the detent spring can preferably be held in such a way that the holding arms end as bent back barbs which are mounted in the pockets of the housing with play.
  • the detent spring can be tilted well if the back, from which the holding arms and the detent arm extend, are bent towards the housing, so that a radius is formed.
  • the spring can then be operated either by hand or with the aid of a button or the like, see DE-A-31 23 825.
  • the detent spring can be stamped from rust-free spring sheet metal or from spring wire.
  • the basic idea of the invention can, however, be implemented with detent springs made from any semi-finished product.
  • Figure 1 shows an electrical connector 1 with a housing 2 made of plastic with two contact and line chambers 3, which are used to hold, if necessary, sealed contact parts, such as. B. sockets, serve.
  • a rubber-elastic seal 6 is inserted on the end face 4 in an annular space 5, and two caps 10 are formed on the top 7 or bottom 8 via a film hinge 9.
  • the caps 10 have four walls.
  • the rear wall 11 merges into the upper wall 12, which is connected to the housing 2 on the end face via the film hinge 9.
  • two side walls 13 adjoin, in which elongated holes 14 are made near the center.
  • the end faces of the pins 16 are provided with bevels 16a which extend in the direction of the caps 10.
  • the slot 14 is approximately parallel to the film hinge 9, so that the caps 10 can be pressed with a certain path from an initial position in the direction of the sides 7 and 8 of the housing 2, d. H. are pivotable about the resilient film hinge.
  • detent springs 17 are mounted under the caps 10.
  • the detent spring 17 is in principle shaped as a three-pronged symmetrical fork made of sheet metal, in particular of stainless spring steel, compare FIGS. 6 to 8.
  • the locking foot 22 ends as a hook 23 bent over 180 °, so that there is an approximately semicircular larger radius R6 .
  • the latching foot 22 itself is slightly curved in a C-shape with a large radius R7.
  • the detent springs 17 are inserted with their barbs 20 into pockets 24 on the top 7 or bottom 8 into the housing 2 so that they can move with a slight axial play X.
  • a passage 25 to the interior of the housing 2 is provided between the pockets 24.
  • a latching cam 26 with a latching surface 27 of a mating connector 28 can be inserted into the passage 25.
  • a stop surface 29 for the detent spring 17 is provided near the end face 4.
  • the surfaces 27 and 29 run approximately parallel: the surface 29 is at an angle of approximately 20 °, the surface 27 approximately 15 ° to the connector end surface 4.
  • the mating connector 28 In the locking position with the mating connector 28 shown in the upper half in FIG. 1, the mating connector 28 is supported on the seal 6 with an annular collar 30.
  • the locking spring 17 lies with the radius R6 of the locking foot 22 on the locking surface 27 and on the outer surface 31, i. H. at an angle of approx. 105 ° to the mating connector 28.
  • the latching foot 22 lies in the area of the radius R7 on the surface 29 of the housing 2. This arrangement allows any manufacturing tolerances to be well balanced so that a good sealing effect is ensured.
  • the detent spring 17 blocks the connection since it is supported mainly on the surface 29 on the housing 2, but also on the detent arm 21 on the top 7 and on the back 18, the holding arms 19 and the barbs 20 on the housing 2.
  • the caps 10 do not need to be charged.
  • the release position of the spring 17 is shown in Figure 4.
  • the locking arm 21 is pivoted by pressure P on the caps 10 in the area of the corrugation R, so that the locking foot 22 moves upward approximately along the surface 29.
  • the holding arms 19 and the locking arm 21 are supported in the region of the radius R4 on the top of the housing 2, see FIG. 1.
  • the mating connector 28 as in the example, the locking cam 26 also has an insertion bevel 32
  • the connectors 1 and 28 can be connected by simply pushing them together.
  • the latching foot 22 is raised by the insertion bevel 32 when it is pushed in, see FIG. 4, and then snaps behind the oblique latching surface 27 of the latching cam 26 after insertion and sealing, and after the electrical contact has been made, as shown in FIG.
