  • a rivet connection 23 is provided.
  • Reference numeral 24 refers to a tab, not visible in the upper picture, with an opening 23 'intended for the riveted connection.
  • a disadvantage of this rivet connection is that a relatively small contact surface between the subunit 7 and the terminal lug 21 is available. This lower contact surface ultimately results in the same current flow to an elevated temperature at the junction.
  • Fig. 3 shows the connection of the contact plate 7 and the terminal lug 21 in a rear view. Again, the rivet 23 is clearly visible.
  • Fig. 4 shows a connection device 30 according to the invention for the device 1 for the exchange of heat.
  • rivet 23 here a clamping connection with two clamping devices 35a and 35b between a first tab 24 of a subunit 7 of the second component and the connection device 30 is used.
  • the tab 24, in this embodiment, has two beveled end portions which facilitate insertion into the clamps 35a and 35b. In addition, rounded corners and the like could be provided. These clamping devices 35a and 35b cause the tab 24 to be pressed against a flat section 36 of the connection device 30.

  • the elements 31 are in this embodiment to resilient elements that ultimately favor pinching the tab 39.
  • the first tab 24 has a predetermined width b.
  • Fig. 5 is a page representation of the presentation Fig. 4 shown. It can be seen that the clamping device 35b presses the tab 24 against the flat portion 36 of the connection device 30. In this way it is achieved that a contact surface between the tab 24 and the flat portion 36 is formed, which results essentially from the product of the width b of the tab 24 and the height h, in which surface portion 36 and the tab 24 overlap results. Furthermore, a contact still comes along the respective side surfaces of the connecting device or the tab 24 and, as in Fig. 4 shown partially on the upwardly facing surface of the tab 24 state. As it turned out Fig. 5 results, the terminals 31 in cross-section on a beak-shaped.

  • the opening angle above the Berntonabitess in this embodiment is greater than below the Berntonabitess.
  • two clamps 31 were used. However, it would also be possible to provide more or fewer clamps instead. Also, a different number of clamping member units could be provided on the two sides.
  • the two clamping devices 35a and 35b in turn have end sections 35'a and 35'b (cf. Fig. 4 ), which cause a further increase in the contact area between the connecting device 30 and the first tab 24.
  • connecting devices in reverse order, d. H.
  • clamping devices on both the connecting device 30 and the first tab 24, which engage in one another.
  • Fig. 6 shows a plan view of the in the 4 and 5 Shown connection device 30. It can be seen here that the end sections 35'b and 35'a are enlarged relative to the remaining sections of the clamping devices 35a and 35b along the direction h. Furthermore, it can be seen that the first tab 24 has a bevelled end portion 26 which facilitates collapse for making the connection between the connectors 24 and 34.
  • Fig. 7 is a sectional view along the lines AA on the device Fig. 6 shown.
  • the regions in which the mechanical connection between the connection device 30 and the first lug 24 comes about are represented in particular by hatching.
  • the area of the first lug 24 surrounded by the clamps 35a and 35b is also available as the contact surface in the area defined by the width b and the height h, as mentioned above. In this case, it is also possible to bring the end regions 35a 'and 35b' closer to the center line M in order in this way to further increase the contact surface.
  • the clamping means 35a and 35b each have an arcuate portion, each having a lateral region the tab 24 at least partially surrounds.
  • the clamping devices preferably contact the lug 24 along substantially this entire arcuate section. Substantially along this entire arcuate section, it is understood that nevertheless in smaller areas, in which the lug 24 faces a strong curvature of the clamping devices 35a and 35b, such as in the FIG. 7 on the underside of the tab 24 sections, no contact may occur.
  • the arcuate portion may be made such that it extends at least partially in the shape of a circular line, but other courses such as elliptical courses are also conceivable.
  • the thickness of the tab 24 projects beyond the thickness of the flat section 36 (indicated by hatching). However, it would also be possible to choose the thicknesses equal or the thickness of the tab 24 is less than the thickness of the flat portion 36th
  • the thickness of the sheet portion 36 is substantially equal to the thickness of the clamps 35a and 35b.
  • the thicknesses could also be chosen differently.
  • the reference numeral 33 refers to a central region of the connecting device 30.
  • This central region has a predetermined height and a substantially rectangular cross section, wherein at the respective longitudinal sides of this central region, the clamping devices 31 for the second tab 39 are arranged.
  • substantially rectangular cross sections other cross sections could be used, such as generally polygonal cross sections, elliptical cross sections, and the like.

The underside of the central region 33 merges directly into the planar section 36, the width of the central region substantially coinciding with the width of the planar section 36.
  • the central region 33 is made of a current-insulating material or surrounded by such a material.
