Definitions

  • the invention relates to a seal, in particular a sealing mat, for at least one electrical connector, in particular for a plurality of connectors.
  • Gaskets for connectors are used in automotive engineering to seal the connection side of an electrically wetted component, for example, a moist side, through the seal through an electrical connector is performed without affecting the tightness to the wet side.
  • a sealing mat a matrix of several passage rows and columns is provided, each passage is assignable only with a connector.
  • a membrane can be formed in the passage of the seal, which is pierced when the seal is covered with a connector and without connector remains intact.
  • Such a seal is from the FR 2 844 645 B1 known.
  • the known seal comprises a base body made of plastic, in which a passage a is formed.
  • a membrane b is formed integrally with the main body.
  • the membrane b has a stepped shape, which consists of two mutually axially offset stepped shoulder portions c and d .
  • the shoulder portions c and d are connected to each other via a predetermined separating skin e .
  • a sealing projection h which extends from the inner wall j from a wide base to a rounded end and defines a passage opening.
  • the well-known step-shaped membrane design ensures that when covering the connector, the membrane b ruptures on the Solltrennhaut e and the electrical contact of the connector reaches the opposite side of the seal.
  • the reinforced shoulder regions c and d ensure that no material of the injured membrane tears off the inner wall j of the passage a and remains at the contact of the connector, so that the risk of unintentional electrical insulation of the contact exists.
  • the projections h are to ensure that the fluid tightness between the top and bottom f, g is ensured in cooperation with the connector performed.
  • the step-shaped membrane structure avoids the probability of undesirable isolation of the electrical contact with a probability bordering on probability.
  • the contact of the connector does not necessarily injure the membrane on the target cut skin. It was found that the membrane is also injured in the piercing process on the membrane base and a part of the injured membrane gets caught on the contact, which leads to the insulation problem. It has also been found that with different widths sized connectors sufficient fluid tightness in performed connectors by the projections is not sufficiently guaranteed.
  • the seal comprises a base body, in which at least one passage is formed for performing a contact of the connector, and a sealing lip arranged in the passage, which forms a fluid-tight manner on the connector made through the passage.
  • the sealing lip is connected by a hinge to the base body in the region of an inner wall of the passage elastically pivotable.
  • the sealing lip deforms according to the pivoting range of the joint and easily adapts to the width dimension of the connector.
  • the pivoting of the sealing lip allows to keep the clear width of the opening defined by the sealing lip small, without having to significantly increase the Eintechnischwiderstand with wide connectors, so that in some applications of the seal even a membrane structure in the passage of the seal are completely omitted could.
  • the hinge provides a pivoting movement of the sealing lip about a pivot axis which lies in the free space of the passage or in the region of the inner wall of the passage.
  • the joint may be formed by a material constriction in the region of the transition from the sealing lip and the inner wall of the passage.
  • the constriction is, for example, a continuously tapering recess in a projection extending from the inner wall of the passage.
  • the joint and the sealing lip is formed in cross-section substantially in a tree shape.
  • the joint and the sealing lip may have the shape of a spade.
  • the hinge extends as a narrow web of an inner wall portion of the passage and merges into a bead-like sealing lip body.
  • the pivoting range of the sealing lip body can be limited by adjusting the axial length of the web.
  • the web may extend from the inner wall region substantially with a constant cross section towards the sealing lip body. The longer the bridge, the more flexible the elastic joint.
  • the sealing lip preferably has an end tapering towards the connector that has been made.
  • the main body, the joint and the sealing lip may be formed from a plastic piece.
  • the structure of the membrane is made of a solid silicone. It has been found that a secure separation of the material is ensured by the inventive selection of solid silicone for the membrane. Particularly good results were achieved in the combination of the sealing material according to the invention and the membrane structure according to the enclosed, above-described Figure 1. It turned out, surprisingly, that regardless of the type of insertion of the connector, the membrane was always torn open at the Solltrennhaut and the material of the injured membrane always remains on the seal body and thus insulation of the contact of the connector is excluded due to membrane material. This improved effect of the membrane behavior when severing a membrane from the solid silicone according to the invention was independent of the external shape of the membrane structure.
  • the main body and the membrane is made of a solid silicone piece.
  • Particularly suitable turned out to be a solid silicone under the trade name "ELASTOSIL ® R plus 4804" is available or "ELASTOSIL ® R plus 4001" by the company Wacker-Chemie GmbH in Kunststoff.
  • solid silicone of the invention comprises a density of 1.0 g / cm 3 to 1.2 g / cm 3, preferably either 1.6 g / cm 3 or 1.12 g / cm 3.
  • the general test method according to DIN EN ISO 1183-1A shall be used.
  • the solid silicone of the invention may have a tensile strength of 5 N / mm 2 to 12 N / mm 2 , preferably 6 N / mm 2 or 11 N / mm 2 .
  • the generally accepted test method DIN 53 504 S is used for this purpose.
  • the solid silicone according to the invention may have values of 7% to 1100%, preferably 750% or 1000%.
  • the tear propagation resistance of the solid silicone according to the invention is preferably set at 12 N / mm to 30 N / mm, preferably 15 N / mm or 27 N / mm.
  • the general test method according to ASTM D 624 B is used.
  • the solid silicone according to the invention can have values of 65% to 70%, preferably 52% to 67%.
  • the compression set of a solid silicone according to the invention may be from 20% to 30%, preferably 22% or 29%.
  • the general test method according to DIN ISO 815-B with a test duration of 52 hours and at a temperature of 175 ° C is used.
  • a self-lubricating solid silicone is used to obtain an optimal solid silicone property according to the invention 30 sec to 60 sec, preferably 40 sec, at a temperature of 155 ° C to 175 ° C, preferably 165 ° C, in particular in one Press vulcanized.
  • a rubbery two-component liquid silicone according to the invention can alternatively be used, which can be brought into the corresponding shape of the seal by means of a injection molding process.
  • the two-component liquid silicone has excellent self-sealing properties obtained by releasing or "sweating out" a liquid under a compressive stress on the two-component silicone.
  • Such a two-component liquid silicone can for example be purchased from the company GE Bayer Silikones under the product name LSR 3596/30 TP 3967.
