  • the male connector thus represents an additional component in the assembly of the control unit.
  • electrical contact surfaces are also known as direct electrical contacts known in which the male connector is omitted and the individual poles of the wiring harness are contacted directly on the circuit board.
  • electrical contact surfaces are provided on the circuit board, which are contacted directly by contact elements of the harness connector.

  • the required pressing force is higher, the higher pole the connector is. Since the pressing force acts on the contact carrier even in the uninstalled state, they must have a certain rigidity, which is achieved via the contact carrier height. With increasing number of poles, ie with increasing contact carrier width, therefore, the contact carrier height must increase accordingly.

  • the circuit board must be slotted to allow the additional spacer (s) to dip. Furthermore, the reduced bending length of the contact carrier minimizes the risk that the electrical contacts may touch due to the sagging of the contact carriers in the uninstalled state of the printed circuit board and damage the electrical contacts due to the bending of the contact carrier during mounting of the printed circuit board on the sharp printed circuit board edge , Further advantages and advantageous embodiments of the subject invention are the description, the drawings and claims removed.

Abstract

L'invention concerne un connecteur (40) permettant une connexion électrique directe à des surfaces de contact (3) prévues sur les deux faces d'un circuit imprimé (2). Le connecteur comprend deux supports de contacts (6), reliés l'un à l'autre de manière articulée et formant entre eux un réceptacle d'enfichage (7) pour l'enfichage du circuit imprimé (2), et au moins un élément de contact (8) respectif pénétrant dans le réceptacle d'enfichage (7) pour établir une connexion électrique directe avec une surface de contact (3). Au moins un ressort (9) précontraint les deux supports de contacts (6) dans une position d'appui dans laquelle les deux supports de contact (6) sont en appui l'un contre l'autre par l'intermédiaire de deux entretoises latérales (31) prévues de part et d'autre du réceptacle d'enfichage (7). Selon l'invention, les deux supports de contact (6) sont en appui l'un contre l'autre, dans la position d'appui, par l'intermédiaire d'au moins une autre entretoise (41) prévue entre les deux entretoises latérales (31).
