Definitions

  • the invention relates to a screw connector configured for screwing into a arranged in a housing for an industrial automation device internal thread for use in hygienically demanding environments.
  • an object of the invention may be considered to provide a connector for use in hygienically demanding environments, which is particularly simple in construction and in which the hygienic requirements are met particularly well and reliably.
  • the screw connector is designed for screwing into a arranged in a housing for an industrial automation device internal thread for use in hygienically demanding environments.
  • the threaded connector has a sleeve and a sleeve, wherein the sleeve an inner portion of the sleeve has a first cylindrical portion and a second cylindrical portion, a first diameter of the first cylindrical portion being larger than a second diameter of the second cylindrical portion having the lower portion a first cylindrical portion mating with the first cylindrical portion and a second cylindrical portion mating with the second cylindrical portion, a collar disposed at a lower end of the sleeve and locked to a lower end of the second cylindrical portion via a first end Part of an outer surface of the second cylindrical portion extends into an inner thread matching outer thread, a transition from the first part to a second part of the outer surface of the second cylindrical portion is configured as a cylindrical ring and has a right angle to the external thread a subordinate sealing region, the sealing region comprises a circumferential groove incorporated
  • the screw-type connectors are configured such that the sealing surfaces are arranged in the interior of the automation component.
  • the sealing plane has now been moved for a hygienic arrangement and no longer sits inside the connector but outside and on the automation component.
  • a particular embodiment provides that the groove is flush with the outer surface of the second cylindrical portion and the surface seal is designed in its thickness greater than a depth of the groove, so that in the assembled state of the ffersteckverbinders between a surface of the housing and a surface of the sealing area the surface seal is arranged compressed so that forms a gap-free transition between the surface of the housing and the cylinder ring.
  • With the transition of the outer surface of the sleeve to the seal on the housing has created a gap-free transition, in which no water / organisms or bacteria can be deposited.
  • a further embodiment provides that the sleeve has a first notch on a hole opposite the external thread and the sleeve has a second circumferential notch, whereby an O-ring between the sleeve and sleeve is held for sealing. Due to the contour of the connector, which includes the groove for the O-ring and the axial securing of the sleeve, the O-ring can be mounted in a defined position and perform there at any time and in any state of assembly its sealing tasks.
  • the sleeve is arranged in such a way in the sleeve, that the sleeve and the sleeve are indeed captive, but the sleeve can still rotate around the sleeve.
  • the external thread is advantageously adapted in its thread length such that the sealing area comes to lie on the housing without gap formation.
  • the sleeve has a hexagonal outer structure, all corners and edges are rounded.
  • the rounded design with little corners and edges minimizes the deposition of Dust, dirt or food particles.
  • the screw connection is also very easy to clean thanks to the round shape.
  • gap-free transitions are achieved by suitably tuning the gasket to the sealing surface of the lower sleeve.
  • gap-free means that the transition areas are at least sufficiently smooth and thus hygienically cleanable for the intended purposes.
  • FIG. 1 shows a housing 2 of an automation component with corresponding electrical connections and their internal threads 3, for example, a screw connector 1 is shown screwed into one of the inner thread 3.
  • the sealing surface of the housing 2 is shown schematically as the surface 5 of the housing.
  • FIG. 2 shows the in FIG. 1 illustrated automation component or its housing 2 in a sectional view through the screw connector 1.
  • the screw connector 1 is designed to be screwed into the housing 2, including in the Housing 2 an internal thread 3 is arranged.
  • the screw connector 1 essentially comprises a sleeve 10 and a sleeve 20.
  • the sleeve 10 is sealed to the sleeve 20 via an O-ring 50.
  • a surface seal 40 In the contact area of the sleeve 20 on the housing 2 is a surface seal 40, wherein the surface seal 40 is arranged in a circumferential groove 41.
  • the screw connector 1 is described in a sectional view in detail.
  • the sleeve 10 is arranged with a lower part in the sleeve 20, to an inner region of the sleeve 20 has a first cylindrical portion B1 and a second cylindrical portion B2.
  • a first diameter d1 of the first cylindrical portion B1 is larger than a second diameter d2 of the second cylindrical portion B2.
  • the lower part has a first cylindrical section A1 matching the first cylindrical section B1 and a second cylindrical section A2 matching the second cylindrical section B2.
  • a collar 30 is arranged, which is latched to a lower end B2U of the second cylindrical portion B2.
  • Extending over a first part 21 of an outer surface AF of the second cylindrical portion B2 is an external thread 4 matching the inner thread 3.
  • a transition Ü from the first part 21 to a second part 22 of the outer surface AF of the second cylindrical portion B2 is considered to be a Cylindrical ring ZR configured and has a right angle to the outer thread 4 arranged sealing region DB.
  • the sealing region DB comprises a circumferential groove 41 incorporated in the cylindrical ring ZR and a surface seal 40 arranged in the groove 41.
  • the groove 41 terminates flush with the outer surface AF of the second cylindrical portion B2 and the surface seal 40 is designed in its thickness slightly larger than a depth of the groove 41, resulting in the sealing region DB a circumferential support ring 42, so that in the mounted state of Screw connector 1 between the surface 5 of the housing and a surface of the sealing region DB, the surface seal 40 is arranged compressed so that forms a gap-free transition Ü between the surface 5 of the housing 2 and the cylinder ring ZR.
  • the circumferential support ring 42 is in the mounted state on the housing 2 and prevents further compression of the surface seal 40th
  • the sleeve 20 has a first circumferential notch 51 on a side facing the external thread opening and the sleeve 20 has a second circumferential notch 52.
  • an O-ring 50 between the sleeve 10 and the sleeve 20 is arranged for sealing.
  • the sleeve 10 is designed such that it can be inserted into the sleeve 20. Upon reaching the collar 30 of the sleeve 10 of the second cylindrical portion B2, the sleeve 10 can be pushed with some effort through the second cylindrical portion B2 until the collar 30 with the lower end B2U of the second cylindrical portion B2 locked and thus the sleeve 10 safely is held in the sleeve 20.
  • the O-ring 50 was inserted into the second circumferential notch 52 of the sleeve 10 and thus comes to lie in the sleeve 20 inserted sleeve 10 for sealing in the first notch 51.
  • the surface seal 40 is pushed over the external thread 4 and arranged in the groove 41 and can thus later form the gap-free transition Ü between the housing 2 and the sleeve 20.
