Definitions

  • the invention relates to a coupling element for an electrical cable according to the preamble of claim 1.
  • Such Coupling element is known from US-A 5 104 342.
  • Coupling elements of this type which are both plugs with pin contacts as well as cans with socket contacts can be used for Detachable connection of multi-core electrical cables used in vehicle construction. she allow for example the connection of the anti-lock braking system (ABS) or electrical braking system (EBS) of a trailer on its towing vehicle. Run the Cable free on the vehicles, so the coupling elements are dirty, Splashing water, shocks and tensile loads. A mechanically robust and construction protected against the ingress of moisture and dirt is therefore advantageous.
  • ABS anti-lock braking system
  • EBS electrical braking system
  • the Coupling element has a protective body produced by injection molding, which encloses the contact carrier and the connected cable. With that the Protective body mechanical protection of the contact carrier and strain relief of the cable with simultaneous sealing.
  • the through holes are pre-molded by individual Sealing elements hermetically sealed. Alternatively or additionally, the Sealed with a hot melt adhesive. This measure is also required to ensure a secure and precise connection of the coupling element is possible with a counter element. Sealing the through holes requires a high workload, which in the case of multi-core cables according to the number of cores increases.
  • US-A-5 104 342 describes a coupling element associated manufacturing process, in which over a populated with contacts, two-piece contact carrier a copper tube is attached.
  • the contacts and in the Both parts of the contact carrier openings are so one on top of the other matched that the openings through the inserted contacts are sealed.
  • the copper tube lies close to the contact carrier and holds the two Parts together. It protrudes on the contact side beyond the one on which Plug can be inserted into the coupling element.
  • the contacts are with Wires of an electrical cable connected on the connection side from the Protrude contact carrier. On this connection side is the copper pipe extending tubular cover attached, which the connected cable should hold in place. An injection molded one lies over the cover Protective body that protrudes above the line.
  • the invention has for its object the above Improve coupling element so that it is easy to manufacture and moisture-proof is.
  • the cover is at one end tight and with a locking function on the contact carrier and overlaps his Openings on the back. It lies at its other end just as close to the cable.
  • the cover thus prevents the injection molding Protective body the penetration of liquid spray material into the openings of the Contact carrier.
  • the cover simplifies the manufacture of the Coupling element in particular with multi-core cables, since a seal of everyone individual wire or each individual opening is no longer required.
  • the Protective body is made by overmolding the ends of the cover. He then encloses the cover and the contact carrier on the one hand and the Cover and the cable on the other hand, so that there is an overall moisture-proof Coupling element results.
  • the protective body consists of two parts, one of which one cover and contact carrier and the other cover and cable surrounds. Such a division of the protective body means less material for the same than is usually required.
  • 1 to 4 is used to connect an electrical Cable 1, its insulated conductors with electrical contacts are connected, which are inserted into openings 7 (Fig. 3) of a contact carrier 2.
  • the area 4 adjoining the front side 3 of the contact carrier 2 is the same of a given shape, so that it is in a counter element, not shown can be used.
  • the outer dimensions of the area 4 and the Arrangement of the contacts in the contact carrier 2 specified.
  • Connection or guide means arranged such. B. pin 5 with complementary components of the counter element cooperate and thus a enable positive connection.
  • the design of the back the coupling element can be varied in the area of the cable attachment.
  • this area of the coupling element is formed by a protective body 6 which is attached to the Contact carrier 2 is injection molded and encloses the cable 1 at the end. It consists in preferred embodiment two separate parts 15 and 16, as shown in FIGS. 2 and 4 is.
  • the contact carrier 2 consists of a comparatively rigid, insulating material, such as a plastic such as polyamide, to ensure a safe, precise and mechanical resilient connection to the counter element of the coupling element enable.
  • the protective body 6 is preferably made of comparatively soft Plastic, like a thermoplastic elastomer (TPE), that one forms shock-absorbing protection for the coupling element. Furthermore, can a soft protective body better adhesion to the flexible, frequent pull and Reach exposed cable 1.
  • TPE thermoplastic elastomer
  • a soft protective body better adhesion to the flexible, frequent pull and Reach exposed cable 1.
  • the latching also ensures a secure connection of contact carrier 2 and Cover 8.
  • locking elements for example Raises or barbs on contact carrier 2 and cover 8, the one Reach out the recess or elevation of the other component.
  • Adequate elastic material enables locking by a resilient restoring force after deformation of the components.
  • the mutual contact surface of Contact carrier 2 and cover 8 preferably parallel walls exhibit.
  • the walls can lie flat against each other or circumferential Have webs that touch the other wall. Through the parallel Alignment of the walls creates a wide sealing surface that prevents penetration of the spray material under the cover 8 prevented.
  • the protective body 6 can consist of two parts 15 and 16 which are separated from one another. Between the two parts 15 and 16 is in the embodiment of the 1 to 3 of the passage 9 of the cover 8. It can during injection molding of the protective body 6 can be narrowed by radial pressure. This also ensures that the spray material of the protective body 6 is not penetrates through the passage 9 into the interior of the cover 8.
  • part 15 of the protective body 6 primarily the joint between the contact carrier 2 and Cover 8 closes moisture-proof and an outer grip surface Handling of the coupling element forms part 16 serves as strain relief Cable 1 and for sealing the passage 9 and thus the Cover 8 on cable 1.
  • the cover 8 is in the Contact carrier 2. This points the contact carrier 2 according to FIG. 3 on its finished Coupling element facing the cable 1 rear side a circumferential groove 17th on.
  • the groove 17 surrounds the openings 7 made in the contact carrier 2, which go through from its front 3 to the back and the recording of contacts. Ribs 18 in the openings 7 allow the contacts to fix by locking.
  • the cover 8 is inserted into the circumferential groove 17 inserted and locked in the end position.
  • Fig. 4 shows a cross section through another embodiment of a Coupling element in which the parts 15 and 16 of the protective body 6 a have a comparatively large distance from each other. Therefore, there is the possibility also the seal between contact carrier 2 and cover 8 by mutual Improve pressing in an injection mold. It is preferred to use the Arrows 19 and 20 marked positions exerted a pressing pressure in the direction of the arrow.
  • the coupling element according to the invention is manufactured, for example, as follows:
