Definitions

  • the invention relates to a coupling element according to the preamble of claim 1 and a method its manufacture.
  • Coupling elements which are both plugs with pin contacts as well as cans with socket contacts can act, among other things, become solvable Connection of multi-core electrical cables in vehicle construction used. For example, they enable connection the anti-lock braking system (ABS) or the electric one Brake system (EBS) of a trailer on its towing vehicle. If the cables run freely between the vehicles, then there are the coupling elements dirt, splash water, Shocks and tensile loads exposed unprotected. A mechanically robust and against the ingress of Moisture and dirt-protected construction is therefore advantageous.
  • ABS anti-lock braking system
  • EBS electric one Brake system
  • a coupling element is known, on the contact carrier, which fixes the electrical contacts, a protective body is injected.
  • the protective body encloses the Cable approach, d. H. at least the section of the cable in which his coat for the electrical connection of the contacts is removed, and the edge of the mantle.
  • the Protective body mechanical protection of the contact carrier as well as a strain relief of the cable at the same time Seal.
  • the contacts must be free of spray material remain to the safe and precise connection of the To enable coupling element with a counter element.
  • the area of the contact carrier in which the contacts are arranged is of a predetermined shape and points if necessary, increases, deepenings or tours for connection and locking with the counter element. It is usually surrounded by a circumferential seal enclosed, for example in a groove in the End face of the contact carrier is arranged.
  • the coupling element stands with a complementary shaped mating element in engagement, which the seal closes. That way is one Contamination of the contacts and the penetration of Moisture in the coupling element along the contacts locked out.
  • only the individual contacts from the liquid Sealing spray material is preferably the entire Area of the seal and contacts free from Spray material to ensure a precise fit to the counter element ensure.
  • the Contacts are often provided with recesses or points Design on that is complementary to the opening cross-section are. Therefore, there is no tight seal.
  • the DE-GM suggests 94 10 092 before, the openings by individual Seal sealing elements hermetically. Alternatively or in addition, the seal can be sealed with a Hot melt adhesive done.
  • the disadvantage is that the sealing of the openings one high workload required for multi-core Cables increase according to the number of wires. Will continue for the production of known couplings comparatively large amount of spray material for the Protective body needs what both the weight as well production costs increased.
  • the central idea of the invention is one provide common cover for the openings.
  • the Cover lies close to the contact carrier and overlaps its openings. It thus prevents the intrusion of the liquid spray material, which after curing Protective body forms.
  • the contacts are in the openings with the wires attached to it through the back Insert preferably completely sunk.
  • the jacket of the cable runs all the way around close to the edges of the passage, the Division of the cable into those leading to the contacts Veins are done inside the cover. Because only a seal against the cable jacket simplified the manufacture of the coupling element in particular with multi-core cables, because each one seals single wire is omitted.
  • the protective body is molded around the cover manufactured, and surrounds them in whole or in part. As well it encloses the cable in the area of the passage. Also part of the contact carrier is from the protective body enclosed or at least borders on it. Through a suitable molding tool ensures that a Area of the surface of the contact carrier free from Spray material remains. In the most general case, the free area excluding the openings and exists thus of several parts; however, it is preferred coherent.
  • the contact carrier consists of a comparatively rigid, insulating material, such as a plastic like Polyamide to ensure a secure, precise fit and mechanical resilient connection with a counter element of the To enable coupling element.
  • the Protective body is a comparatively soft plastic preferred, such as a thermoplastic elastomer (TPE), a shock absorbing protection for contact carriers and Cover forms. It can also be used for a soft Protective body better adhesion to the flexible, frequent Reach cables exposed to tensile and bending loads.
  • His coat also consists of a comparatively soft material such as a polyurethane, e.g. B. the thermoplastic elastolane.
  • the proposed coupling element is characterized by a mechanically robust structure that is safe Strain relief and water sealing of the cable attachment causes.
  • the manufacturing effort is compared coupling elements known from the prior art significantly reduced. Weight is also reduced and material costs due to the under cover remaining cavity inside the Coupling element.
  • the non-positive connection is preferably carried out Positive locking.
  • Locking elements for example, are suitable for this Raises or barbs of contact carriers or Cover that a recess or increase of each reach behind another component. Adequate elastic material enables locking by a resilient restoring force after deformation of the Components.
  • the form fit can also through the protective body by removing parts of Contact carrier and cover reach behind.
  • a non-positive is Connection by appropriate coordination of the materials from Contact carrier, cover and protective body within reach an adhesive connection of the materials when molding of the protective body.
  • the Materials react chemically with each other or merging superficially.
  • the mutual contact surface of the contact carrier and Cover preferably from parallel to each other Walls formed.
  • the walls can be flat lie against each other or have circumferential webs, which touch the other wall. Through the parallel Alignment of the walls creates a broad Sealing surface, the penetration of the spray material under the cover even if it is in the Edge area of the sealing surface occurs.
  • the one Form sealing surface of the cover to the contact carrier has expediently the outer wall is larger Flexibility on than the wall on the inside.
  • the pressure of the spray material squeezes the Walls during the formation of the protective body against each other, so that the sealing effect improves.
  • cover and Interlock contact carrier in a groove is the component inserted into the groove outside wall and the inner boundary of the groove the inside wall.
  • Different flexibilities the walls can be both by means of different materials as well, especially at same materials of cover and contact carrier, achieved through a suitable design. In the latter It is useful if the cover is the outside wall forms. Easy deformability can then be in the direction of the cable cause elongated shape of the cover.
  • a dimensionally stable inner wall is by struts or others Supports reachable. For example, it is by the outer surfaces of the central area of the contact carrier formed in which the openings for receiving the contacts are arranged.
  • the passage of the cover for the cable a tubular shaft with a substantially cylindrical, extended in the axial direction Inner surface is provided. That way too a secure seal between the cover and the cable ensures a wide sealing surface.
  • tubular shaft protrudes from the outside of the cover.
  • the protective body from two spaced apart Divide.
  • a part encloses the cable as well as the Contact carrier facing away edge of the passage; he educates the sealing and strain relief of the cable attachment.
  • the cover Of the other part adjoins and encloses the contact carrier the cover so that it prevents moisture penetration prevented into the plug interior. In many cases it forms the Most of the outer surface of the coupling element.
  • the distance remaining between the two parts opens the Possibility during the injection molding of the protective body exert radial compressive forces on the cover. On this way, a safe one during spraying Sealing by compressing the passage on the Cable and / or cover and contact carrier guarantee.
  • the molding tool under pressure on the walls of the cover whose inner surfaces are a sealing surface to the cable or form to the contact carrier.
  • the contact pressure is like this high that the cover deforms and gaps be closed to form a cable jacket or contact carrier.
  • the cover is preferably provided with a shaft-shaped passage provided on the elements of the Mold can be pressed during the injection molding process.
  • the protective body thus produced consists of one another spaced parts or at least has recesses which, as a result of the pressing of the elements of the Tools remain on the cover.
  • the coupling element is used to connect a electrical cable (1), the wires with contacts in Stand in a contact carrier (2) are used.
  • the on the front (3) of the Contact carrier (2) adjoining area (4) of the Coupling element is of a predetermined shape, so that he insert himself in a counter element, not shown leaves.
  • the outer outline of the area (4) and the arrangement of the contacts specified; furthermore here are connection or guide means like e.g. B. pin (5) arranged with complementary Components of the counter element interact and thus enable a positive connection.
  • connection or guide means like e.g. B. pin (5) arranged with complementary Components of the counter element interact and thus enable a positive connection.
  • the design of the back of the coupling element in The area of the cable attachment can be varied. Usually this area of the coupling element from one Protective body (6) formed on the contact carrier (2) is molded and encloses the cable (1) at the end.
  • the protective body (6) of two parts (15, 16) spaced apart are. Your connection is made exclusively by a end shaft (17) of the cover (8), the Passage (9) encloses. So there is the possibility through the shaft (17) when the protective body (6) is sprayed to narrow a radial pressure. So that is ensures that the spray material is not through the Passage (9) penetrates into the interior of the cover (8). While part (15) primarily the joint between Contact carrier (2) and cover (8) moisture-proof closes and the outer grip surface for handling the Forms coupling element, part (16) serves as Strain relief of the cable (1) and to seal the Passages (9).
  • Fig. 3 gives a view of the back of the contact carrier again, which faces the cable (1) and on which the cover (8) is put on.
  • the openings (7) are arranged, which connect the back with the front (3) and in which the contacts can be inserted. Ribs (18) in the openings (7) allow the contacts through To fix locking.
  • the openings (7) are from enclosed an inner wall (19) which is perpendicular to the Drawing plane over the surface of the contact carrier (2) protrudes.
  • the cover (8) can be on the Slide on the outside of the wall (19), whereby a there is a tight seal against the spray material.
  • Figure 4 shows the cross section through another Design of the coupling element in which the parts (15, 16) of the protective body (6) a comparatively have a large distance. Therefore there is the possibility also the seal between the contact carrier (2) and Cover (8) by pressing against each other in the Improve mold. It is preferred to use the an arrow (21) marked positions in a pressure Arrow direction exercised. The positive connection of contact carrier (2) and cover (8) takes place in this Fall only through part (15) of the protective body (6), one with both components when molded load-bearing connection.
  • the result is a moisture-proof and tensile load-bearing coupling element, which with a low Effort and inexpensive to manufacture.
