Definitions

  • the invention relates to an elongate element with an outer Sheath and an electrical connector at the end, which is integral to the sheath is fixed, and a method of manufacture.
  • the invention has set itself the task of having an element to develop a cohesively attached electrical connector regardless of the size and shape of the connector with little effort can be made.
  • This object is achieved in that a ring is present which is pushed onto the element and attached with a hardened adhesive whose jacket is fixed, and that the connector is attached to the ring.
  • the main idea of the invention is to start with a ring on the element fix cohesively to which the connector is then attached. To this way, the volume required to fix the molds required is reduced the dimensions of the ring usually much smaller than that of the Are connectors.
  • a uniform ring can be used in different ways Attach the shaped connector to the element. This reduces the number of required tools considerably.
  • the production is advantageously carried out in such a way that the ring first on the Element is pushed on.
  • elements of varying cross-section such as a cable with the end removed Sheath, which may have a stop for the ring.
  • a liquid adhesive medium e.g. a plastic or glue in their Penetrate the space and causes a resilient force when it hardens Connection.
  • a non-positive connection can be made between jacket and connector through a layer of the adhesive medium encloses both outside.
  • the ring is preferably made of rigid material, e.g. a metal or a Plastic like polyamide.
  • the connector is electrically contacted depending on the fastener used before or after it is fastened on the ring. If necessary, the connector consists of several parts and can be attached to one or more of them on the ring put together.
  • the element according to the invention with a connector is characterized by a secure Strain relief with simple assembly. Instead of a conventional, multi-part screw connection, only a single ring is required, so that the manufacturing effort is reduced. In addition, through the cohesive Fixing the ring to the jacket a permanently moisture-tight seal reachable. Radial loads on the element in the area of the ring are avoided.
  • the ring and the jacket of the element sprayed and / or cast together are, for example, a polymer mixture based on Polyurethanes and / or polyester. It is advisable to coordinate the Materials, especially adhesive medium and coat, so that a resilient Connection arises, for example through fusion or chemical reaction in the Area of the interface for which a heat treatment can optionally be carried out. In addition, especially on the surface of the ring, they are form-fitting Connections possible through undercut. Ring and jacket are preferred overmolded or cast around, so that the ring partially outside is enclosed by the adhesive medium. If there is play between the ring and the coat, this fills Adhesive medium their space and thus improves the tightness and Resilience of the connection.
  • the adhesive medium is, for example, a polymer mixture based on Polyurethanes and / or polyester. It is advisable to coordinate the Materials, especially adhesive medium and coat, so that a resilient Connection arises, for example through fusion or chemical reaction in the Area of the interface for which a heat treatment can
  • the ring and the jacket it is possible to connect the ring and the jacket to one another glue.
  • the adhesive medium which in this case also has gaps between the ring and Filling the coat is, for example, a resin or hot melt adhesive.
  • the ring is preferred in the longitudinal direction of the element by an elastic Spout continued, which encloses the coat and possibly a part of the ring.
  • the spout forms a bending protection for flexible elements. Is next to it through them an improvement in the fixation of the ring on the jacket can be achieved.
  • the spout is expedient in the case of an encapsulation or encapsulation of the jacket and Ring formed and is in one piece with the adhesive medium.
  • the jacket and ring are joined together by casting, there is a covering layer an advantage, which lies on the edge of the jacket and the poured area limited.
  • the cladding layer is on the ring attached or molded to it.
  • the ring is made of plastic, for example Polyamide, it is preferably formed in one piece with the cladding layer. In the case of one the spout adjoining the ring is preferred by the outer surface of the Sheath layer formed, while its interior consists of the hardened casting material.
  • the outer diameter of the ring in its edge area approximately the outer diameter of an adjoining section of the element.
  • the ring is a continuation of one Cable sheath arranged at the end of the cable for contacting one below screen is removed.
  • the Outer diameter of both approximately the same is the same, so that an encompassing spout here can have an approximately constant internal diameter and cross section.
  • the element is a cable that contacts the connector.
  • Conceivable is, however, also that the element is a protective hose or jacket in which Pull in one or more cables or conductors to contact the connector to let.
  • the ring precludes several elements. There are preferably spaces between the elements inside the ring as well if necessary, poured a prefabricated spout, for example through a Hot melt adhesive or a casting resin. This way it is simple and safe Sealing and strain relief of all elements within reach while in place the technique of inserting multiple elements into a connector as special proves to be elaborate. If a subsequent encapsulation of the ring takes place, is a rigid casting material is preferred, which is dimensionally stable under the injection pressure. Also Spaces in an element, such as the wires of a cable, can be seal like this.
  • the ring expediently has in an area which, after being attached to the Element is freely accessible, one or more areas for handling with one Tool on. If the ring is to be screwed to the connector, be level Areas of advantage on its circumference to which a wrench can be attached is.
  • the ring can have a circumference designed as a hexagon own or with a pair of flat surfaces on opposite Peripheral pages. Recessed or raised areas are also conceivable for attaching other handling tools.
  • the element is provided with electrical shielding, it is generally required that it contact the connector housing.
  • the ring is made of electrically conductive material and a fixing element has, in which the shielding can be determined.
  • a clamping ring is advantageous can be screwed onto the ring and has a conical inner surface which the shield presses all around against the surface of the ring. In this way a defined, all-round contacting of the shielding is possible.
  • Fig. 1 gives the view of an element, for example a cable with a Jacket (1) and an end connector (2) again.
  • Your mutual A ring (3) provides strain relief and sealing. He's through one overmolding in areas, which is formed into a spout (4), on the jacket (1) fixed.
  • the definition of e.g. Steel ring (3) on the connector (2) done by screwing.
  • a detachable attachment of the contact carrier (5) on Housing part (6) of the connector (2) makes it possible to contact the wires of the Element after screwing the ring (3) into the connector (2) to make.
  • Fig. 2 shows the partially cut view of an element with slipped ring (3) before and after the encapsulation in a mold.
  • the encapsulation is shaped into a spout (4), the Spray material preferably into the space (7) between ring (3) and jacket (1) penetrates so that the definition improves.
  • the connection of ring (3) and The grommet (4) is undercut by undercuts at the interfaces optimized.
  • the ring (3) is already in with its thread (8) screwed a connector (2).
  • a spout (10) inside the ring (3) for example with a Hot melt adhesive, which is made before the nozzle (4) is sprayed on. So that is it is also possible instead of the individual element shown in the figure, to guide several elements tightly and without strain through the ring (3).
  • Fig. 4 shows the cross section through a ring (3) with a shield (11) an element is connected, which runs under the jacket (1).
  • the ring (3) does not fall onto the jacket (1) as in the previous examples. pushed but adjoins it on the face side and only encompasses the ladder (9).
  • the shield (11) is attached to the ring (3) in such a way that it first around the edge around a binding wire (12) and thus in one circumferential groove (13) of the ring (3) is set.
  • a conical clamping ring (14) screwed onto the ring (3) that holds the shield (11) presses against its surface and it slides out with the binding wire (12) the groove (13) prevented.
