Figur 3 zeigt den in Figur 1 bereits dargestellten Durchbruch 28, wobei die Rinne 5 des Einpresskontakts 1 die Innenwand 29 des Durchbruchs 28 auf einem Umfangsabschnitt 39 elektrisch kontaktiert. Die Länge des Umfangsabschnitts 39 entspricht dabei einer Summe der Umfangsabschnitte 19, 18, 17, 20 und 21 der Rinne 5 in Figur 2. Die Federschenkel 3 und 4 sind nach einem Einführen in den Durchbruch 28 des Schal- tungsträgers 30 auf den Durchmesser 35 radial nach innen zur Längsachse 32 hin eingefedert.

Die Rinne 5 ist so ausgebildet, von der in Figur 2 dargestellten U-Form im expandierten, also nicht eingepressten Zustand beim Einpressen zu einer in den Figuren 3 und 4 dargestellten C-Form radial nach innen einzurollen. Die Rinne hat dabei ihren Durchmesser im Expandierten Zustand auf die Durchmesser 35 und 41 im eingepressten Zustand verkleinert. The channel 5 is designed to roll radially inwards from the U-shape shown in FIG. 2 in the expanded state, that is to say not pressed in, when pressed in to form a C-shape shown in FIGS. 3 and 4. The channel has thereby reduced its diameter in the expanded state to the diameter 35 and 41 in the pressed state.

Figur 5 zeigt den in Figur 1 bereits dargestellten Einpressstift 43 in einem Längsschnitt entlang der Längsachse 32. Die Rinne 5 weist einen in Figur 2 bereits dargestellten Rinnenboden 16 auf. Der Rinnenboden 16 weist im Bereich des Längsabschnitts 6 eine zum Ende 36 zunehmende Dicke auf. FIG. 5 shows the press-fit pin 43 already shown in FIG. 1 in a longitudinal section along the longitudinal axis 32. The channel 5 has a channel bottom 16 already shown in FIG. The channel bottom 16 has in the region of the longitudinal section 6 to the end 36 increasing thickness.
Der Rinnenboden im Längsabschnitt 7 weist in diesem Ausführungsbeispiel eine konvexe Wölbung 46 auf. Eine Bodendicke 49 des Rinnenbodens 16 nimmt auf dem Längsabschnitt 7 zu dem auf dem Längsabschnitt 8 gebildeten Hals des Einpressstiftes 43 hin zu. Die konvexe Wölbung bewirkt einen im Folgenden in Figur 6 dargestellten zum Ende des Einpressvorganges schwächer ansteigenden Kraftverlauf beim Einpressen in einen Durchbruch wie den Durchbruch 28 in Figur 1 . The channel bottom in the longitudinal section 7 has a convex curvature 46 in this embodiment. A bottom thickness 49 of the channel bottom 16 increases on the longitudinal section 7 to the neck of the press-fit pin 43 formed on the longitudinal section 8. The convex curvature causes a force curve, which is shown below in FIG. 6, to be weaker at the end of the press-fitting process when being pressed into an opening, such as the opening 28 in FIG.
Der Rinnenboden 16 kann in einer anderen Ausführungsform - gestrichelt dargestellt - eine gerade ansteigende Form aufweisen, was in einen gleichmäßigen Kraftanstieg beim Einpressen bewirkt. The channel bottom 16 may in another embodiment - shown in phantom - have a straight rising shape, which causes a uniform increase in force during pressing.
Der Rinnenboden 16 kann in einer anderen Ausführungsform - gestrichelt dargestellt - eine konkave Form 47 aufweisen, was in einen gleichmäßigen Kraftanstieg beim Einpressen bewirkt. Eine Dicke 49 des Rinnenbodens 16 - beispielsweise in der Mitte - des Längsabschnitts 7 ist größer als eine Dicke 50 des Rinnenbodens 16 im Bereich des Längsabschnitts 2. The channel bottom 16 may in another embodiment - shown in phantom - have a concave shape 47, which causes a uniform increase in force during pressing. A thickness 49 of the channel bottom 16 -for example in the middle-of the longitudinal section 7 is greater than a thickness 50 of the channel bottom 16 in the region of the longitudinal section 2.
Die Längsabschnitte 2, 6 und 7 bilden zusammen die Rinne 5. The longitudinal sections 2, 6 and 7 together form the channel 5.
Figur 6 zeigt ein Diagramm 51 mit einer Abszisse 52 und einer Ordinate 53. Die Abszisse 52 repräsentiert einen Einpressweg des in den Figuren 1 und 5 dargestellten Einpressstiftes 43 entlang der Längsachse 32, insbesondere in linearer Darstellung. Der Kontaktbereich, gebildet durch den Längsabschnitt 2 ist nach dem Einpressen in dem Durchbruch 28 in Figur 1 angeordnet wobei die Federschenkel 3 und 4 radial nach außen gegen die Innenwand 29 des Durchbruchs 28 in Figur 1 pressen. FIG. 6 shows a diagram 51 with an abscissa 52 and an ordinate 53. The abscissa 52 represents a press-fit path of the press-fit pin 43 shown in FIGS. 1 and 5 along the longitudinal axis 32, in particular in a linear representation. The contact region, formed by the longitudinal section 2, is arranged in the aperture 28 in FIG. 1 after being pressed in, wherein the spring legs 3 and 4 press radially outwardly against the inner wall 29 of the aperture 28 in FIG.
Die Ordinate 53 repräsentiert eine Einpresskraft zum Einpressen des Kontaktstiftes in den Durchbruch 28 in Abhängigkeit des Einpressweges, insbesondere in linearer Darstellung. Dargestellt ist auch eine Kurve 54, welche eine Einpresskraft zum Einpressen des Kontaktstiftes 43 in den Durchbruch 28 in Abhängigkeit des Einpressweges entlang der Längsachse 32 repräsentiert. The ordinate 53 represents a press-in force for pressing the contact pin into the opening 28 as a function of the press-in path, in particular in a linear representation. Shown is also a curve 54, which represents a press-in force for pressing the contact pin 43 into the opening 28 as a function of the press-fit path along the longitudinal axis 32.
Ein Wegabschnitt 55 der Kurve 54 weist einen Kraftanstieg 56 auf, welcher durch die Wölbung 46 in Figur 5 bewirkt wird. Der Kraftanstieg 56 ist zu einem Ende 60 des Einpressweges entlang der Längsachse 32 des Einpressstiftes 43 schwächer als zu Beginn des Einpresswegs. A path portion 55 of the curve 54 has a force increase 56, which is caused by the bulge 46 in Figure 5. The force increase 56 is weaker towards an end 60 of the press-fit path along the longitudinal axis 32 of the press-fit pin 43 than at the beginning of the press-fit path.
Dargestellt ist auch ein Kraftanstieg 57 beim Einpressen des Einpressstiftes 43, welcher der gerade ansteigenden Längsform des Rinnenbodens 16 auf dem Längsabschnitt 7 entspricht. Die Kraft zum Einpressen des Einpressstiftes 43 mit der Form 47 nimmt gemäß dem Kraftanstieg 57 entlang des Einpressweges gleichmäßig zu. Der Kraftanstieg 58 entspricht der konvexen Form 48 des Rinnenbodens 16 auf dem Längsabschnitt 7 und ist entlang des Einpressweges allmählich ansteigend, und zum Ende hin stärker ansteigend. Shown is also an increase in force 57 during the pressing of the press-fit pin 43, which corresponds to the straight increasing longitudinal shape of the channel bottom 16 on the longitudinal section 7. The force for press-fitting the press-fit pin 43 with the mold 47 increases uniformly according to the force increase 57 along the press-fitting path. The force increase 58 corresponds to the convex shape 48 of the channel bottom 16 on the longitudinal section 7 and is gradually increasing along the press-in path, and rising more towards the end.
Ein Wegabschnitt 61 der Kurve 54 entspricht einem Einführen des Endabschnittes 15 in den Durchbruch 28, wodurch bei anfänglichem radialen Abwinkein der Federschenkel 3 und 4 ein großer Kraftanstieg entlang des Einpressweges bewirkt wird, welcher durch die zu dem Längsabschnitt 2 hin abnehmende Dicke des Rinnenbodens 16 auf dem Längsabschnitt 6 kleiner wird. Der Kraftverlauf beim Einpressen des Einpressstifts 43 ist so von einem Dickenverlauf des Rinnenbodens 16 der Rinne 5 entlang der Längsachse 32 abhängig und kann über den Dickenverlauf der Dicke des Rinnenbodens 16 eingestellt werden. A path portion 61 of the curve 54 corresponds to an insertion of the end portion 15 in the opening 28, whereby at an initial radial Abwinkein the spring legs 3 and 4, a large increase in force along the Einpressweges is caused, which by the longitudinal section 2 towards decreasing thickness of the channel bottom 16 the longitudinal section 6 is smaller. The force profile during the pressing of the press-fit pin 43 is thus dependent on a thickness profile of the channel bottom 16 of the channel 5 along the longitudinal axis 32 and can be adjusted over the thickness profile of the thickness of the channel bottom 16.
Die Kurve 59 repräsentiert einen Kraftverlauf eines Einpressstiftes mit gleichmäßiger Bodendicke und/oder Schenkellänge. Sichtbar ist der Kraftabfall zum Ende 60 des Einpressweges hin. The curve 59 represents a force curve of a press-in pin with a uniform bottom thickness and / or leg length. Visible is the force drop towards the end 60 of the press-in path.
