Definitions

  • the invention relates to an electrical connector, as is known in a similar form from DE-A-31 23 825.
  • a U-shaped spring clip made of wire serves as a detent spring.
  • the detent spring can be brought from a locking position into a release position via a release button arranged on the housing.
  • a plug of a similar type is known from EP-A-0 351 083.
  • One end of a leaf spring is molded with a plastic to form a button.
  • buttons make it easier to release the lock.
  • the detent springs are exposed to any kind of external influences.
  • the invention is based on the endeavor to provide an electrical connector of the type mentioned, in which the spring or springs is or are well protected against external undesirable influences of any kind.
  • the invention provides the characterizing features of claim 1.
  • the invention ensures on the one hand that environmental influences such as splash water, mud, dust and the like can no longer act unhindered on the detent spring.
  • the complete coverage means that no mechanical attacks, in particular during transport or assembly, can act on the detent spring.
  • the cap-shaped cover offers optimal protection, because e.g. laterally applied forces are dissipated to the housing.
  • other sections of the cable set e.g. a single cable, hooked behind the unprotected locking spring.
  • hooking or excessive mechanical action by impact or the like can lead to deformation, displacement or even tearing of the spring, so that the locking function in the connector is disturbed or is even completely eliminated.
  • 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 and 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 elongated hole 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, ie 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 in 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 rests with the radius R6 of the locking foot 22 on the locking surface 27 and on the outer surface 31, ie at an angle of approximately 105 °, of the mating connector 28.
  • the latching foot 22 bears against the surface 29 of the housing 2 in the region of the radius R7.
  • 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 latching arm 21 are supported in the region of the radius R4 on the upper side 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.
