Definitions

  • the invention relates to a multi-part contacting component according to the preamble of patent claim 1 and to a method for producing a contacting achieved therewith, in particular for gear or motor controls in the automotive industry.
  • Integrated mechatronics in particular control electronics, which are used directly on site, for example in a transmission or in an engine, are subject to a large number of environmental requirements.
  • control electronics which are used directly on site, for example in a transmission or in an engine
  • the increased operating temperatures and the chemically aggressive environment of the engine or transmission oil are in the foreground. Therefore, it is essential that the sensitive electronics and sensors are protected as far as possible from these influences.
  • the conception of the control electronics on the one hand and the connected peripheral components such as sensors or valves on the other hand represent a major challenge.
  • the proposed contacting comprises a contact strip for one or more cables and the arrangement of a special contact with a welding lug at the cable end.
  • the cables are fixed by the contact strip in a predefined position. Due to the multipart design of the contacting device, an additional stability in the contact area is achieved, which, however, is fixed in its orientation to the horizontal.
  • a contact plug with at least two housing parts.
  • a foil conductor is placed in a first housing part and provided with a seal.
  • the seal also causes a bias of the film conductor.
  • the second housing part is inserted into the first housing part and the foil conductor is electrically conductively connected to the terminal area of the pin contact.
  • a disadvantage of such a connector construction is, in addition to the lack of flexibility in the design of the plug above all the fact that a seal must be used. Especially for integrated mechatronics, the use of seals is less suitable because of the high mechanical, chemical and thermal loads on the connectors. The long-term stability of the plug is thus reduced and it can form fractures just in the sealing area over the intended lifetime.
  • the object of the invention is therefore to provide a simplified concept for the construction of a Maisticiansbaumaschine for mechatronics, which allows a less expensive installation just of contacts in a vertical orientation to the electronics base plate with very good absorption of later insertion forces and simultaneous safe to tear leadership of the flexible circuit board.

  • the other requirements such as a possible tolerance compensation of the relative movement base plate / Ansteckteil and span réelle coverage of the contact points are met.
  • the modular design of at least one support member and a Fuhrungsteil also allows a cost-effective and flexible adaptation of the component to different lent specifications, for example, the number and spacing of the individual contact paths of the flexible circuit board.

In this parallel position, the electrical connection between the flexible printed circuit board and the plug device of the guide part can be produced. This is particularly preferably done by laser welding. Finally, by further pivoting of the Fuhrungsteils and locking the vertical position to the support member can be achieved.

Abstract

Composant de contact (1) en plusieurs pièces pour des mécanismes électroniques, comprenant au moins un élément de fixation (2) et au moins un élément de guidage (3) indépendant de celui-ci et doté d'un dispositif connecteur mâle (4). L'élément de guidage (3) est enfiché sur l'élément de fixation (2) de manière à pouvoir être amené par rotation dans une position parallèle par liaison de forme avec l'élément de fixation (2). Dans cette position, une extrémité d'une carte imprimée (5) flexible, ladite extrémité dépassant de l'élément de fixation (2), est placée entre les deux éléments. Si on continue à tourner l'élément de guidage (3), il arrive dans une position finale perpendiculaire à l'élément de fixation (2). Le composant de contact (1) en plusieurs pièces facilite tout d'abord la mise en place de connecteurs notamment dans la position perpendiculaire difficile en raison du guidage de la carte imprimée flexible. La coopération de l'élément de fixation (2) et de l'élément de guidage (3) garantit une protection suffisante vis-à-vis des conditions ambiantes, notamment des courts-circuits des contacts d'une carte imprimée (5) flexible. De plus, cela rend superflu tout embobinage ou toute insertion des extrémités de la carte imprimée (5) flexible.
