Gemäß der zeichnerischen Darstellung ist der Isolierkörper 13 nach Art eines rechteckförmigen Rahmens mit vier umlaufenden Schenkeln 21, 22, 23 und 24 ausgebildet, von denen jeweils die beiden Längsschenkel 21 und 22 und die beiden Querschenkel 23 und 24 im Wesentlichen parallel zueinander verlaufen. Die einzelnen Schenkel 21 bis 24 besitzen jeweils etwa gleiche Dicke. Die Unterseite 26 des Isolierkörpers 13 ist dem einen elektrischen Bauelement 11 und die Oberseite 27 des Isolierkörpers 13 dem anderen elektrischen Bauelement 12 zugewandt. Der hintere Längsschenkel 22 besitzt eine über die wesentliche Länge des Randes verlaufende Randausnehmung 28, während die beiden Querschenkel 23 und 24 an einem dem hinteren Längsschenkel 22 abgewandten Bereich eine relativ kurze Randausnehmung 31 und einen dazu parallel verlaufenden Schlitz 32 aufweisen.According to the drawing, the insulating body 13 in the manner of a rectangular frame with four circumferential legs 21, 22, 23 and 24 formed by which the two longitudinal legs 21 and 22 and the two cross legs 23 and 24 substantially parallel to each other. The individual legs 21 to 24 each have approximately the same thickness. The bottom 26 of the Insulator 13 is the one electrical component 11 and the top 27 of the insulating body 13 the other facing electrical component 12. Rear Longitudinal leg 22 has a substantial length of the edge running edge recess 28, while the two cross legs 23 and 24 on one the rear Longitudinal leg 22 facing area a relatively short Edge recess 31 and a parallel to it Have slot 32.

Die metallischen Kontakte 14, die jeweils ausschließlich in einer Längsausrichtung verlaufen, sind in einem Einspannbereich 41 vom im Spritzgussverfahren hergestellten Isolierkörper 13 umspritzt. Jeder metallische Kontakt 14 besitzt einen freien und frei bewegbaren Endbereich 36, an dessen gebogenem Ende die konvexe Außenfläche den vorderen Kontaktpunkt 19 bildet. Der freie Endbereich 36 besitzt eine langgestreckte Trapezform, deren schmale Grundseite 37 in den vorderen Kontaktpunkt 19 einstückig übergeht und deren breite Grundseite 38 einstückig in einen mit parallelen Seitenrändern versehenen Kragbereich 39 übergeht, der in den Einspannbereich 41 innerhalb des Längsschenkels 22 des Isolierkörpers 13 übergeht. Der Einspannbereich 41 ist zur Unterseite 26 des hinteren Längsschenkels 22 abgekröpft und verjüngt sich zum den hinteren flächigen Kontaktbereich 18 aufweisenden Ende 42, wobei die Kontaktfläche 18 die Unterseite 26 des Längsschenkels 22 des Isolierkörpers 13 überragt. Mittels ihrer hinteren Kontaktfläche 18 sind die Kontakte 14 mit den nicht im Einzelnen dargestellten Kontaktflächen 16 des einen elektrischen Bauelementes 11 verlötet. Das Ende 42 der Kontakte 14 ragt außerdem in die Randausnehmung 28 des hinteren Längsschenkels 22. Der Kragbereich 39 verläuft etwa parallel zum Ende 42 bzw. zur Unterseite 26 des Isolierkörpers 13. Der Übergang 44 vom Kragbereich 39 zum freien Endbereich 36 ist derart gebogen, dass der freie Endbereich 36 unter einen spitzen Winkel aus der Ebene des Isolierkörpers 13 zum anderen elektrischen Bauelement 12 hin verläuft. Der Kragbereich 39 liegt teilweise an der Unterseite 52 einer Stufe 49 an, die im hinteren Längsschenkel 22 des Isolierkörpers 13 parallel zu dessen Unterseite 26 vorgesehen ist und die in die etwa trapezförmige Ausnehmung 51 des Rahmens des Isolierkörpers 13 hineinragt.The metallic contacts 14, each exclusively in longitudinal alignment are in one Clamping area 41 made by injection molding Insulated body 13 overmolded. Any metallic contact 14 has a free and freely movable end region 36 the curved end of which the convex outer surface the front Contact point 19 forms. The free end region 36 has an elongated trapezoidal shape, the narrow base 37 integrally merges into the front contact point 19 and the broad base 38 in one piece with one cantilever region 39 provided with parallel side edges passes into the clamping area 41 within the Longitudinal leg 22 of the insulating body 13 merges. The Clamping area 41 is towards the bottom 26 of the rear Longitudinal leg 22 bent and tapered to the rear flat contact area 18 having end 42, wherein the contact surface 18 the bottom 26 of the Longitudinal leg 22 of the insulating body 13 protrudes. through the rear contact surface 18, the contacts 14 with the contact surfaces 16 of the not shown in detail an electrical component 11 is soldered. The end 42 the contacts 14 also protrudes into the edge recess 28 of the rear longitudinal leg 22. The cantilever region 39 extends approximately parallel to the end 42 or to the bottom 26 of the Insulating body 13. The transition 44 from the cantilever area 39 to free end region 36 is bent such that the free End region 36 at an acute angle from the plane of the Insulator 13 to the other electrical component 12 runs there. The cantilever area 39 is partially on the Bottom 52 of a level 49 at the rear Longitudinal leg 22 of the insulating body 13 parallel to it Bottom 26 is provided and in the approximately trapezoidal recess 51 of the frame of the insulating body 13 protrudes.

In den Schlitz 32 der Querschenkel 23, 24 des Isolierkörpers 13 ist ein Lötwinkel 46 mit seinem einen Schenkel 47 eingesteckt, dessen anderer dazu senkrecht verlaufender Schenkel 48 in die Randausnehmung 32 ragt. Dieser Schenkel 48 verläuft an der Unterseite 26 des Isolierkörpers 13 und ist mit einer entsprechenden metallischen Gegenfläche am einen elektrischen Bauelement 11 lötend verbindbar. Dadurch ergibt sich eine stabile mechanische Verbindung zwischen dem Isolierkörper 13 und dem einen elektrischen Bauelement 11. In the slot 32 of the cross legs 23, 24 of the Insulating body 13 is a soldering angle 46 with its one Leg 47 inserted, the other perpendicular to it extending leg 48 protrudes into the edge recess 32. This leg 48 runs on the underside 26 of the Insulator 13 and is with a corresponding metallic counter surface on an electrical component 11 solderable connectable. This results in a stable mechanical connection between the insulating body 13 and one electrical component 11.

Wird das andere elektrische Bauelement 12 in Richtung des Pfeils A mit seinen entsprechenden Kontaktflächen 17 auf die vorderen Kontaktpunkte 19 der Verbindungsvorrichtung 10 gebracht und nach unten gedrückt, ergibt sich eine mit einem bestimmten Kontaktdruck versehene lötfrei kontaktierende elektrische Verbindung. Bei einer Bewegung des Endbereichs 36 zum Isolierkörper 13 hin (Pfeil A) verformt sich der breitere Kragenbereich 39 ebenfalls so, dass der Kontaktpunkt 19 im Wesentlichen parallel zur Unterseite des Isolierkörpers 13, also etwa horizontal verbleibt. Es verseht sich, dass das elektrische Bauelement 12 zu Aufrechterhaltung der elektrischen Verbindung mit dem Kontakt 14 an der elektrischen Verbindungsvorrichtung 10 oder an bzw. in einem Gehäuse oder dergleichen mechanisch fixiert und gehalten wird.If the other electrical component 12 in the direction of Arrow A with its corresponding contact surfaces 17 the front contact points 19 of the connecting device 10 brought and pressed down, there is one with one certain contact pressure provided solderless contacting electrical connection. When the end area moves 36 to the insulating body 13 (arrow A) deforms the wider collar area 39 also so that the contact point 19 substantially parallel to the bottom of the Insulating body 13, ie remains approximately horizontal. It oversees yourself that the electrical component 12 to maintain the electrical connection to the contact 14 the electrical connection device 10 or on or in mechanically fixed to a housing or the like and is held.

Durch die oben beschrieben Bewegung und Verformung des Endbereichs 36 bzw. des Kragenbereichs 39 entsteht ein Drehmoment, das zu einer Verbiegung des Längsschenkels 22 führen kann. Um dem entgegenzuwirken können wie in Fig. 4a dargestellt Auflagenasen 50 zwischen den Kontakten 14 vorgesehen werden die eine zusätzliche Auflagefläche auf dem Bauelement 11 bieten und eine Versteifung darstellen.Through the movement and deformation of the end area described above 36 or the collar area 39, a torque is generated, that lead to a bending of the longitudinal leg 22 can. To counteract this, as shown in Fig. 4a Lugs 50 provided between the contacts 14 become an additional contact surface on the component 11 offer and represent a stiffener.

Wie aus Fig. 4b erkennbar liegt die Auflagefläche 62 dieser Auflagenasen 50 in einer Ebene mit den Kontaktflächen 16.As can be seen from FIG. 4b, the bearing surface 62 of this lies Support tabs 50 in one plane with the contact surfaces 16.
