Definitions

  • the invention relates to a press-in female connector for pressing into bores in a printed circuit board, with contact springs made from a sheet metal strip, each having a connection area with a press-in part which is essentially perpendicular to the printed circuit board and an angled contact area which is essentially parallel to the printed circuit board.
  • the press-in principle on which the known female connector is based is also problematic, since it is provided that the pressure exerted perpendicularly to the printed circuit board from above by pressure surfaces in the pressure block is transferred to the contact areas of the contact springs running parallel to the printed circuit board. This can lead to undesirable bending moments and buckling during further power transmission to the angled press-in parts.
  • the invention has for its object to provide a press-in spring bar of the type mentioned, which can be pressed in from above with a flat punch without risk of damage.
  • a one-piece insulating body supported by an L-shaped metal bracket is provided, in which the contact springs are arranged in such a way that the press-in parts protrude freely so that a pressure block made of plastic material protrudes from the press-in part side the Isolierstoffkorper is pushed on, that the pressure block has cutouts for the contact springs and is formed on the press-in part side with press-in surfaces parallel to the printed circuit board, that the contact springs in the connection area each have two press-in shoulders, and that the connection area each has a fixed angle to the rest of the contact spring in such a way is twisted that the press-in shoulders interact with the press-in surfaces.
  • FIG. 1 shows a plan view from above in the direction of the printed circuit board on a female connector according to the invention
  • FIG. 2 and 3 show a longitudinal or cross section through the spring strip according to FIG. 1.
  • the basic structure of the press-in female connector can be seen from FIG.
  • the contact springs are each individually arranged and fastened in the insulating body (5), which in turn is carried by a metal bracket (4).
  • the more precise structure of the female connector and in particular of the pressure block (6) can be seen better from the representations according to FIGS. 2 and 3.
  • FIG. 2 the press-in parts (2) projecting axially downward in the direction of the printed circuit board can be seen. While only the rear wall of the pressure block (6) can be seen in the left part of FIG. 2, the right part of the figure shows schematically how the contact springs inside the pressure block (6) are saved. The torsion area (10) of the contact springs can also be seen.
  • FIG. 3 shows the insulating body (5) carried by the metal bracket (4) together with the front plate (9) and the inserted pressure block (6).
  • the contact springs each have two press-fit schools (8) in the connection area (1).
  • the printing block (6) is, at first undetected Contact springs, pushed on from below so far that the press-in surfaces (7) are arranged somewhat above the press-in shoulders (8).
  • the connection areas are then twisted at an angle of approximately 75 to 105 °, it being advantageous if the contact springs in the torsion area (10) have a narrower point. Due to the torsion, the press-in surfaces (7) come to lie exactly above the associated press-in school (8), so that this occurs by means of a flat stamp. Press-in pressure exerted above is applied very close and in line with the press-in zone. As a result, neither bending moments nor buckling can occur.
  • Plastic hooks integrated in the pressure block (6) which engage behind corresponding points on the metal bracket (4), ensure that the enclosed contact springs are permanently attached.

Abstract

Afin de pouvoir enfoncer le connecteur multipolaire à ressorts coudé, depuis le haut, à l'aide d'un poinçon plat, il est prévu un corps isolant (5) porté par une cornière métallique (4) en L et sur lequel est poussé, depuis la face de la pièce à enfoncer, un bloc-poussoir (6). Ce dernier (6) présente des cavités destinées à des ressorts de contact et présente, côté pièce d'enfoncement, des surfaces de poussée (7) parallèles à la carte de circuits. Chaque ressort de contact comporte dans la zone de connexion (1) deux épaulements de poussée (8) et la zone de connexion (1) est coudée selon un angle fixe par rapport à la partie restante du ressort de contact, de manière que les épaulements de poussée (8) coopèrent avec les surfaces de poussées (7).
