Definitions

  • the invention relates to an electrical connector according to the preamble of claim 1.
  • Electrical connectors are used in many areas of electrical engineering, for example in communications, control, measurement and regulation technology and in vehicle construction.
  • the housing of such connectors is often round and is manufactured in a wide variety of sizes.
  • the connector has a different number of contacts in the form of a pin or socket.
  • cables are used which are surrounded by a shield, which is usually formed from a metal wire mesh.
  • the shielding of the cable is connected in an electrically conductive manner to the housing of the plug connector in such cases.
  • the electrical plug connection is also subject to special requirements with regard to moisture tightness, for example when used in factory halls, in vehicles or outdoors.
  • a connector is known in which separate components are provided for the electrical connection between a cable shield and the connector housing and for sealing the same.
  • the component used for sealing is sleeve-shaped and consists of electrically non-conductive elastomer material.
  • a basket-shaped clamping element presses an inner edge of the sleeve-shaped sealing component, the inside diameter of which is larger than the outside diameter of the cable including its insulation, against the cable insulation.
  • a contact element in the form of an open ring made of non-conductive elastomer material is known, which is coated with a conductive layer, for example made of a wire mesh or a thin metal foil.
  • the ring-shaped contact element which rests directly on a cable shield and establishes the electrical connection between it and a connector housing, is not suitable for sealing against moisture due to the sheathing with wire mesh or metal foil.
  • a cable grommet made of electrically conductive, elastic material is known, which is used for feeding shielded cables into electronic devices comes and makes the electrical contact between the cable shield and a housing of the electronic device. A special sealing of the cable feed against moisture is not achieved with this cable grommet.
  • an electrical connector in which a sleeve-shaped elastomer part made of electrically conductive material is provided for producing good ground contact between a cable shield and the connector housing.
  • the sleeve-shaped elastomer part sits at one end of the cable directly on the shielding braid, which has been exposed by removing a piece of the cable insulation, and is held between two likewise sleeve-shaped housing parts which are arranged concentrically to one another and are connected by means of a screw connection.
  • the sleeve-shaped elastomer part When the two sleeve-shaped housing parts are screwed together, the sleeve-shaped elastomer part is pressed essentially radially against the shielding braid and thus establishes a good electrical connection between the cable shielding and the connector housing.
  • a separate seal arranged on the cable insulation and also an O-ring seal arranged between the two sleeve-shaped housing parts.
  • the invention has for its object to provide an electrical connector for shielded cable that can be easily and quickly installed, ensures perfect contact between the shield and the housing even when the installation is not optimal, can be easily opened and then reassembled and can also be protected against moisture sealed and should be inexpensive to manufacture.
  • the elastomer part which has the shape of a sleeve or sleeve pushed over the end of the cable, takes on both the sealing against moisture and the electrically conductive connection between the cable shield and the connector housing due to its axial compression in the installed state.
  • the electrical conductivity of normally non-conductive, resilient material can be achieved in various ways.
  • the elastomer part is interspersed with electrically conductive wires, for example fine metal wires.
  • the elastomer material itself is electrically conductive.
  • elastomers can be made electrically conductive by adding metal powder to them during manufacture. The electrical conductivity can also be achieved by a thin metal surface coating of the resilient material.
  • the elastomer part is preferably arranged coaxially with the cable and the housing of the connector.
  • the elastomer part can be made with oversize and pressed into the connector housing.
  • the elastomer part is particularly preferably held by a screw connection in the housing.
  • the screw connection compresses the elastomer part in the axial direction, which ensures a good seal against moisture and perfect contact with the connector housing under all circumstances. At the same time, the assembled connector can be easily opened again.
  • the elastomer part has a shoulder on the outside in the axial direction, so that an end section of the elastomer part facing the housing has a smaller outside diameter than an opposite end section facing away from the housing.
  • the cable expediently extends through the elastomer part, a metal braid forming the cable shield being folded back over the end section with a smaller outer diameter.
  • the elastomer part viewed in the axial direction, is arranged between two electrically conductive rings.
  • the front ring serves as a stop and ensures that the folded-up metal braid of the cable shield is pressed evenly against the elastomer part, while the rear ring arranged between the elastomer part and the screw connection prevents a rotational movement from being transmitted to the elastomer part when the screw connection is screwed into the housing becomes.
  • the outside of the sleeve-shaped elastomer part is conical.
  • a bushing with a conical inside is preferably arranged around the elastomer part.
  • the elastomer part is cut open in the axial direction. The elastomer part can then be placed without difficulty around a part of the cable shield, which in this embodiment is knocked back over the cable insulation.
  • the cable shield is here not folded back over the elastomer part, but rather the elastomer part surrounds the part of the shield that has been pushed back.
  • An electrical connector 10 has an essentially circular cylindrical housing 12 with an axially continuous interior 14.
  • a plurality of wires 32 of an electrical cable 30 are led into the interior 14.
  • the cores 32 extend through the interior 14 to form a contact carrier (not shown) seated in a metal socket, the individual cores 32 having contacts arranged in the contact carrier, for example by soldering or crimping are electrically connected.
  • the metal frame (not shown) is screwed to the housing via a thread 16 formed in the front part, which is also made of metal, on the left in FIG. 1.
  • an elastomer seal 18 is arranged which seals the connection between the metal frame and the housing 12.
  • a knurled nut 20 concentrically surrounding this is plugged onto the metal frame.
  • the knurled nut 20 is rotatably held in the usual manner by a collar formed on the metal socket and has an internal thread for screwing with a complementary mating connector, not shown.
  • a sleeve-shaped elastomer part 22 made of electrically conductive material is pushed over an outer insulation 31 of the end of the cable 30 facing the plug connector 10.
  • the outside of the elastomer part 22 has a shoulder, so that a front end section 24 of the elastomer part 22 facing the plug connector 10 has a smaller diameter than an opposite, rear end section 23 the shield 34 of the cable 30 consisting of a metal braid is knocked back.
  • Two metal rings 25 and 26, the function of which will be discussed in more detail, and a screw 27 with armored thread 27a are also pushed onto the cable 30.
  • the thread 27a fits into a corresponding thread 28 which is designed as an internal thread in the rear part of the housing 12.
  • the connector 10 is assembled as follows: First, the cable 30 is prepared in a conventional manner for connection to the connector 10, ie the insulation 31 of the cable is removed a little from the end of the cable, without damaging the shield 34. Then the screw 27, the metal ring 26 and the elastomer part 22 are pushed one after the other over the cable end. The inside diameter of the sleeve-shaped elastomer part 22 is somewhat smaller than the outside diameter of the cable 30 with insulation, so that the elastomer part 22 sits tightly on the cable 30. As can be seen from FIG. 1, the elastomer part 22 is pushed onto the cable 30 until the end face of the elastomer part 22 facing the housing 12 approximately ends with the end of the outer cable insulation 31.
  • the portion of the shield 34 projecting beyond the end of the cable insulation is flipped back over the end portion 24 of the elastomeric member 22.
  • the cable end thus prepared is pressed by hand into the housing 12 of the connector 10. This is easily possible since the outer diameter of the rear end section 23 of the elastomer part 22 is somewhat smaller than the inner diameter of the thread 28.
  • the screw 27 is screwed tightly into the internal thread 28 of the housing 12.
  • surfaces 13 are provided on the outside of the housing 12, which allow a wrench or pliers to be attached. The connection of the wires 32 to the contacts, not shown, takes place in a conventional manner and therefore need not be explained in more detail.
  • the elastomer part 22 is compressed by the screw 27 in the axial direction, its diameter has increased so that the outer surface of the end portion 23 is in close contact with the internal thread 28.
  • the metal ring 25 serves as a stop for the elastomer part 22 and, to further improve the contact between the housing 12 and the shield 34, ensures that it is pressed firmly against the elastomer part 22.
  • the metal ring 26 is arranged between the screw 27 and the elastomer part 22.
  • the elastomer part 22 is made of electrically conductive material with the due to the intimate contact Housing 12 made a perfect, electrically conductive connection between the shield 34 and the housing, the elastomeric part 22 at the same time seals the connector well against moisture due to the material and the axial compression in the housing.
  • FIG. 3 Another embodiment of the electrical connector 10 is shown in FIG. 3. It differs from the exemplary embodiment shown in FIGS. 1 and 2 primarily by the different shape of the elastomer part 22.
  • the outside of the sleeve-shaped elastomer part 22 has no step, but is instead conical.
  • the side of the elastomer part 22 with the larger outside diameter faces the housing 12 of the connector.
  • a bushing 21 is provided in the second embodiment, the inside of which is also conical.
  • the inside of the bushing 21 is dimensioned such that the bushing can be pushed onto the elastomer part 22.
  • the bushing 21 has a not shown, radially inwardly projecting and serving as a stop peripheral edge, which prevents the bushing 21 from being pushed too far onto the elastomer part 22 by force.
  • the screw 27 has In this exemplary embodiment, in the area of its thread 27a, there is a cylindrical inner recess arranged concentrically to the latter, the diameter of which is larger than the outer diameter of the bushing 21.
  • the bushing 21 is arranged concentrically around the elastomer part 22 and transmits the force introduced via the screw 27 and acting in the axial direction to the elastomer part 22, so that it is compressed in the axial direction.
  • the shield 34 is not pushed back over the elastomer part 22, but over the cable insulation 31.
  • the elastomer part 22, which is cut open in the axial direction according to FIG. 5, is then placed over the folded-back shield 34 and the bush 21 is then pushed onto the elastomer part 22 by hand.
  • the cable end thus prepared is then pressed into the housing 12 of the connector 10.
  • the screw 27 is then firmly screwed into the internal thread 28 of the housing 12.
  • the inner recess of the screw 27 shown in FIG. 4 has a centering effect with respect to the bushing 21, so that the bushing 21 is pressed evenly onto the elastomer part 22 and compresses it in the axial and radial directions.
  • the bushing 21 prevents the elastomer part 22 from rotating when the screw 27 is screwed in.
  • the elastomer part 22 is pressed firmly against the front metal ring 25 and the inside of the housing 10 and against the shield 34 or the cable insulation 31, so that a perfectly electrically conductive and at the same time moisture-proof connection between the Shield and the connector housing created is.
  • the combination of the conical elastomer part 22 with the bushing 21 has a strain-relieving effect on the cable 30.
  • the slot 22a indicated in FIG. 5 and resulting from the cutting of the elastomer part 22 in the axial direction can also have a shape other than that shown in FIG. 5. 5, one or more grooves can also be provided, in which complementary projections engage.
  • the slot 22a closes to complete tightness.
