  • the radial projection can form an integral part of the connecting element body. This means that the radial projection is formed in one piece, i.e. as a block of material, with the connecting element body and provides the connecting element.
  • connecting element body In order to avoid the creation of thermally and/or mechanically heavily stressed areas on the connecting element body, it is proposed that it be essentially cylindrical.
  • the connecting element body can thus be designed with a substantially constant and large diameter over its entire length. Only in the area of the radial projection is there a variation in the radial dimension.
  • a tool attack formation is formed in an outer peripheral region of the radial projection.
  • the tool attack formation can comprise two mutually essentially parallel outer circumferential surface sections of an outer circumferential surface of the radial projection, so that during an assembly process or a disassembly process of a supply line, the connecting element can be fixed against rotation by pliers or a wrench.

  • the biasing unit can comprise at least one biasing spring, preferably a disc spring.
  • a local mechanical overload of the first support element by the biasing unit can be avoided, for example, in that the at least one biasing spring is supported on the first support element in the first axial direction by means of a first disk-like transmission element.
  • This first disk-like transmission element can be constructed, for example, with metal material.
  • connection element can be supported on the second support element in the second axial direction by means of a second disk-like transmission element constructed, for example, with metal material.

  • An exhaust gas heater 16 is arranged upstream of the exhaust gas treatment unit 14.
  • the exhaust gas heater 16 comprises a heating area constructed, for example, with a heating conductor, through which the exhaust gas A flows.
  • the exhaust gas A absorbs heat and transports it to the exhaust gas treatment unit 14 following downstream. In particular in operating phases in which the exhaust gas A emitted by the internal combustion engine is still comparatively cold or the exhaust gas treatment unit 14 has not yet reached its operating temperature for carrying out a catalytic reaction , this can ensure faster heating of the exhaust gas treatment unit 14.
  • connection unit 18 In order to apply the electrical voltage used to heat the heating area of the exhaust gas heater 16, a connection unit generally designated 18 is used for the connection to each pole of an on-board voltage network.

  • connection element 20 In a first axial end region 24 to be positioned inside the exhaust system component 12, the connection element 20 has an exhaust gas heater connection region 26, in which the connection element 20 or the connection element body 22 is connected in an electrically conductive manner, for example by a weld 28, to a heating region 30 of the exhaust gas heater 16 .
  • connection element 20 In a second axial end region 32 to be positioned outside the exhaust system component 12, the connection element 20 has a supply line connection region 34, in which it is or can be connected to a supply line generally designated 36 in the manner described below.
  • the supply line connection area 34 comprises an end section 38 of the connection element body 22 and a radial projection 40 adjoining the end section 38 and preferably completely encircling the longitudinal axis L.
  • the radial projection 40 which is integral with the connection element body 22, i.e. formed as a block of material, provides a planar projection 40 relative to the longitudinal axis L essentially orthogonal contact surface 42 for the supply line 36 or a cable lug 44 or the like provided thereon.
  • An external thread 46 is provided on the end section 38 of the connecting element body 22, so that a nut 48 can be screwed onto this end section 38 in order to secure the supply line 36, for example the cable lug 44 to be anchored on the supply line connection area 34 of the connection element 20.
  • the radial projection 40 comprises a tool attack formation 50, which, for example, can comprise essentially parallel outer peripheral surface sections 52, 54 of an outer peripheral surface 56 of the radial projection 40 on two regions of the radial projection that are diametrically opposite one another with respect to the longitudinal axis L.

  • the radial projection 40 can be attacked with a tool in order to rotate the connection element 20 prevent and thus ensure that the nut 48 can be screwed on with a defined tightening torque.
  • the connecting element body 22 Due to the essentially cylindrical design of the connecting element body 22, even in the area of the end section 38, it is therefore also easy to release the supply line 36 or the cable lug 40 of the same in order to loosen or replace the supply line 36 by removing the nut 48 and then axially away from it End section 38 can be pulled off without having to overcome a clamping force. This makes it easier to assemble and disassemble the supply line 36, particularly in areas of a vehicle or the exhaust system 10 that are difficult to access.
  • the radial projection 40 provides a comparatively large outer surface in the manner of a cooling fin, so that local overheating due to the heating caused by the Exhaust gas flowing around the exhaust heater connection area 26 or the comparatively large electrical current flowing through the connection element 20 can be avoided.
  • connection unit 18 comprises a ring-shaped carrier element 58 made of metal material.

  • the first support element 68 is held radially centered, with essentially no radial movement play being present between the first recess wall 72, which preferably runs completely around the longitudinal axis L in the circumferential direction, and the first support element 68. Due to the essentially flat contact of the first support element 68 on the first recess base 70 and the essentially radially play-free adjoining of the first support element 68 to the first recess wall 72, a labyrinth-like sealing interaction between the carrier element 58 and the first support element 68 is provided.
  • a temperature-resistant, for example disk-like, sealing element could be arranged between the first support element 68 and the first recess base 70.
  • the first support element 68 further has a first support element opening 75, through which the connection element body 22 of the connection element 20 is guided essentially without radial play.

  • the second support element 78 which is accommodated in the second support recess 84 and is axially supported in the second axial direction R 2 and adjoins the second recess wall 82 in a radially outward direction essentially without movement play, is thus supported in a defined axial and radial position on the carrier element 58 and also ensures its second support element opening 86, which is penetrated by the connection element body 22 essentially without movement play, for a further defined positioning of the connection element 20 in the support element opening 76. Furthermore, a further labyrinth-like sealing formation is formed by the interaction of the second support element 78 with the second support recess 84, so that a an even further improved gas-tight seal on the connection unit 18 is guaranteed.
  • a disk-like sealing element for example, could also be arranged between the second support element 78 and the second recess bottom 80.
  • the supporting unit 66 further comprises a biasing unit generally designated 88.
  • the biasing unit 88 comprises two disc springs 90, 92 arranged in opposite directions to one another.
  • the disc spring 90 is also its outer peripheral region is supported on the radial projection 40, and the disc spring 92 is supported in its outer peripheral region via an annular disk-like transmission element 94 on the first support element 68.

On the one hand, there is the possibility of fixing the supply line 36 simply and with a defined fastening torque on the supply line connection area 34 or removing it from it again without having to overcome any friction or clamping moments. Due to the comparatively large and constant cross section of the connecting element body 22, it is also suitable for receiving comparatively large electrical currents, due to the provision of the radial projection 40 and the cooling effect that can be achieved by it, even when heated by the exhaust gas A or that passed through the connecting element 20 Electric current prevents excessive heating in the area of the connection unit 18.
