Definitions

  • the invention relates to a connector and more particularly to a cable seal for a connector.
  • the function of the seal is to seal the passage of the cable in the interior of the housing, so that moisture and dirt can not penetrate into the interior of the housing.
  • the most different constructions are known from the prior art to ensure the seal on the cable.
  • a connector which uses a sleeve-shaped sealing element for each cable exit. This has a collar which rests on an outer side of the connector housing. On the side facing away from the connector housing side of the sealing element, a pressure element is placed, which presses the sealing element radially inwardly, so that is sealed between a guided cable and the connector housing or the pressure element.
  • the object of the invention is to provide a connector with a seal that seals particularly well in the region of the passage of the cable and allows to integrate several cables in a cable seal.
  • the pressure plate fulfills two functions. First, it presses the seal firmly against the housing, so that the seal between the seal and the housing is ensured. On the other hand, the pressure plate causes a deformation of the seal, due to which the seal firmly rests on the cable and seals well there. The compression surfaces can effectively push the seal directly against the cable.
  • screws can be used so that the pressure plate can be screwed in practice on site with little effort.
  • the screws are preferably arranged so that the seal is compressed evenly between the pressure plate and the housing.
  • FIG. 1 shows a connector 1 is shown, which has a first plug-in module 2 and a second plug-in module 3, which are arranged on opposite sides of a partition wall 4.
  • Each plug-in module 2, 3 is associated with a clamp 5, in which an indicated cable 8 is clamped, the wires can be guided to the corresponding plug-in module 2.
  • Each clamp 5 serves both to strain relief and for contacting a shield surrounding the cable.
  • the plug-in modules 2, 3 are arranged on opposite sides of a partition wall 4 in the interior of a housing 10.
  • the partition wall 4 and the housing 10 are made either of metal or of metallized plastic; In this way, a shield against electromagnetic interference is obtained and, due to the partition wall 4, a high crosstalk attenuation between the two plug-in modules 2, 3rd
  • the housing 10 has a rectangular cross-section and has an end wall 12 on its side remote from the plug-in modules 2, 3, in which a first through-opening 14 for a cable to be connected to the first plug-in module 2 and a second through-opening 16 are formed for a to be connected to the second plug-in module 3 cable.
  • the end wall 12 is arranged slightly set back so that a circumferential, over the end wall 12 projecting skirt 18 is formed.
  • a stop surface 13 is provided on the front wall.
  • a seal 20 is arranged, which is provided with a first passage opening 22 and a second passage opening 24.
  • the two sealing passage openings 22, 24 are coaxial with the two housing through-holes 14, 16.
  • the seal 20 is made of an elastomer, in particular a soft rubber.
  • a pressure plate 26 is arranged, which is also located in the space enclosed by the skirt 18 space.
  • the pressure plate 26 is made of plastic or metal and has a first passage opening 28 and a second passage opening 30.
  • the first pressure plate through hole 28 is coaxially aligned with the first seal through hole 22 and the first housing through hole 14.
  • the second pressure plate through hole 30 is coaxially aligned with the second seal through hole 24 and the second casing through hole 16.
  • two screws 32 are provided, which are screwed into two threaded openings 34 in the end wall 12.
  • the housing passage openings 14, 16 are each formed within a cylindrical projection 36 (see in particular FIG. 3), which extends from the end wall 12 into the interior of the housing 10.
  • the cylindrical projection 36 is provided on its inner side facing the interior of the housing 10 with a conical constriction 38, which is limited to the passage opening 14, 16 by a compression surface 40.
  • the compression surface 40 thus has a shape complementary to a truncated cone.
  • the seal 20 has around each passage opening 22, 24 around a cylindrical projection 42, wherein in each case a projection 42 is provided on each side of the body of the seal 20.
  • the seal 20 is mirror-symmetrical with respect to a plane which coincides with the median plane of the body of the seal 20 and is perpendicular to the axis of the two through-holes 22, 24.
  • the outer diameter of the cylindrical projections 42 of the seal 20 corresponds approximately to the maximum diameter of the housing through-holes 14, 16.
  • the pressure plate 26 is also provided with a cylindrical projection 44 around its passage openings 28, 30.
  • each pressure plate lug 44 is provided with a conical constriction 46 which is bounded on its inside by a compression surface 48.
  • the maximum diameter of the housing through-holes 14, 16 and the pressure plate through holes 28, 30 corresponds approximately to the outer diameter of the cylindrical projections 42 of the seal 20.
  • the cables to be connected are usually first pushed through the through holes in the pressure plate 26, the through holes in the seal 20 and the through holes 14, 16 in the end wall 12 of the housing 10 and connected to the two plug-in modules 2, 3, the are provided on both sides of the partition wall 4 provided in holding devices. Subsequently, the two plug-in modules 2, 3 are inserted with the partition 4 in the housing 10.
  • the passage openings for the cables are sealed by placing the seal 20 in the space enclosed by the skirt 18 and placing the pressure plate 26 on the seal. Then, the pressure plate 26 is pressed by means of the screws 32 against the end wall 12, whereby the seal 20 is compressed between the pressure plate 26 and acting as a counter surface end wall 12.
  • the cylindrical projections 42 of the seal 20 are inserted into the conical constrictions 38, 46 in the end wall 12 of the housing 10 and the pressure plate 26, whereby the seal is compressed radially inwardly in this area.
  • two compressed portions 50 of the seal 20 can be seen, which are formed at the inlet end and at the outlet end of the sealing passage opening. In this Area the gasket 20 is firmly attached to the corresponding cable, so that a reliable seal with a high IP protection class is achieved.
  • the seal approach 42 serves at the same time with its both sides compressed sections 50 as cable protection grommet.
  • the pressure plate 26 ensures a uniform loading of the seal 20, so that a uniform and thus very good seal is achieved. Due to the advantageous arrangement of the two screws 32 diagonally opposite each other only very few screws are required to connect the pressure plate 26 evenly with the end wall 12 of the housing. An excessive compression of the seal is prevented by the stop surface 13, on which the pressure plate 26 can come into abutment and which ensures a minimum distance of the pressure plate from the end wall. Particularly noteworthy is that evenly several cables can be sealed in the region of the outlet from the housing.
