Definitions

  • the invention relates to a printed circuit board connector for surface mounting with a plurality of contact elements arranged in an essentially cuboid insulating body and with connecting means for electrically connecting the contact elements to contacting surfaces located on a printed circuit board.
  • PCB connectors for surface mounting are already available in different versions.
  • a connector for SMD technology in which the contact elements have specially designed contact legs that protrude from a strip-shaped insulating body. These contact legs extend to the contacting surfaces on the printed circuit board.
  • the contact elements of the known connector are arranged, for example, in three rows of contact elements one above the other, each of the rows of contact elements containing a large number of individual contact elements lying next to one another.
  • the contact legs leave the insulating body in a direction running parallel to the circuit board and are then angled towards the circuit board. They end in contact stamps which are provided for a soldered connection to the contacting surfaces arranged on the printed circuit board.
  • a row of contacting surfaces is assigned to each row of contact elements on the printed circuit board in such a way that the contact legs of each row of contact elements run without crossing to the contact legs of the respective other rows of contact elements.
  • the arrangement of the contacting surfaces in several rows requires a relatively large amount of space for connecting the contact legs on the printed circuit board, particularly in the case of multi-row plug connectors.
  • the object of the present invention is therefore to provide a circuit board connector according to the preamble of claim 1, with which the edge region of a circuit board can be optimally used for the connection of a large number of contact elements and also contact elements with a very low electrical contact resistance are available.
  • a printed circuit board connector designed according to the invention allows an arrangement of contacting surfaces on both sides of a printed circuit board, the thickness of the printed circuit board being insignificant, since the flexibility of the printed circuit boards allows the printed circuit board connector designed according to the invention to be adapted to different printed circuit board thicknesses.
  • FIG. 1 shows the front F of a printed circuit board connector SV designed according to the invention.
  • the end faces of a large number of contact elements can be seen in the rectangular area of the front side F.
  • the circuit board connector SV is mounted in front of an end face SF of a printed circuit board L, the course of which is indicated on both sides of the front side F shown.
  • the plurality of contact elements K are arranged in rows running parallel to the circuit board level.
  • the circuit board connector SV is attached to the front side SF of the circuit board L in such a way that several rows (in the example five rows) of contact elements K1 are arranged above the circuit board level and several rows of contact elements K2 are arranged below the circuit board level. Between these contact elements K1, K2, which are arranged above and below the circuit board level, there are two rows of contact elements K3 approximately at the level of the end face SF of the circuit board L.
  • a contact element SK designed for current transmission which in the example shown is designed as a three-lamella contact spring for contacting a vertically standing contact knife (not shown) on both sides.
  • FIG. 2 shows a cross section through the central region (section line II-II in FIG. 1) of the printed circuit board connector according to FIG. 1 together with the associated edge region of the printed circuit board L.
  • the insulating housing I of the circuit board connector SV is arranged in front of the end face SF of the circuit board L at a right angle to the circuit board level.
  • the contact elements K1, K2, K3 run parallel to the circuit board level and penetrate the insulating body I from its front side FS to the rear side RS, which runs parallel to the end face SF of the circuit board L at a short distance in front of the latter.
  • the contact elements K1, K2 located above and below the circuit board level protrude on the rear side RS of the insulating housing I with their contacting needles KN from the insulating housing I.
  • the contact elements K3 located at the end face SF have rigid solder lugs LO, which likewise protrude from the insulating housing I on the rear side RS and rest on the upper side OS of the printed circuit board L.
  • the contact elements K3 arranged in front of the end face SF of the printed circuit board are designed as double contacts DK with two electrically connected individual contacts lying one above the other.
  • a circuit foil LF nestles against the rear side RS of the insulating housing I, which forms a loop SL towards the circuit board L and ends parallel to the circuit board level on the upper and lower side OS, US of the circuit board L.
  • the contacting needles KN protruding from the insulating housing I in the horizontal direction are passed through plated-through holes (not shown) on the conductor foil LF and soldered to associated conductor tracks (not shown).
  • the conductor foil LF is reinforced with a stiffening plate V.
  • the contacting surfaces WK for the rigid soldering lugs LF of the contact elements K3 located in the intermediate area are arranged directly on the edge of the top side of the printed circuit board OS.
  • the contacting surfaces KO for the connection of the circuit foils LF are arranged on the upper side OS and on the lower side US of the circuit board L. These contacting surfaces KO lie on the top and bottom of the circuit board L in a single row (not visible) parallel to the edge of the circuit board L.
  • the conductor tracks (not visible) on the conductor foils LF are soldered to the contacting surfaces KO.
  • FIG. 3 shows a cross section through a side part ST of the printed circuit board connector SV according to FIG. 1 (section line III-III).
  • the two side parts ST of the circuit board connector SV are designed as a flange for mechanically attaching the insulating body I to the circuit board L.
  • Two superimposed contact elements SK designed for current transmission are integrated in each flange.
  • contact elements SK are each provided with a contact extension KF, which is provided for resting on associated contacting surfaces of the printed circuit board L.
  • a contact element SK is provided for the current transmission for the upper side and one for the lower side of the circuit board.
  • the contact element SK provided for the underside of the circuit board is accommodated in the insulating body I in a contact chamber KK, which allows the contact element SK and its contact extension KF to be displaced in a direction perpendicular to the circuit board plane.
  • the flange is fastened to the printed circuit board L with two screws S, which are electrically insulated from the contacting extensions KF.
