Definitions

  • the invention relates to a connector for printed or otherwise manufactured printed circuit boards, in particular according to the preamble of patent claim 1.
  • the solution according to the invention specified in claim 1 offers the particular advantage of direct contacting of the busbar by a slight modification of existing indirect card plugs, the invention being characterized in that an additional contact spring is used on at least one narrow side of the contact spring strip of the connector for contacting several plug connectors Busbar via a recess in the corresponding narrow side of the protective collar of the contact spring strip.
  • the additional contact (s) into a chamber-like projection that is open on the side and off the narrow side of the contact spring strip provided for the contact with the busbar projects by a piece which corresponds approximately to the wall thickness of the protective collar of the contact strip. A corresponding recess is then provided on the protective collar, via which the contacting access of the additional contact spring (s) is ensured.
  • the conductor rail itself can be clipped into plastic hooks molded onto the housing part of the knife or pin contact rail or held by additional spring elements connected to this housing part in such a way that the height of the conductor rail can be varied in a simple manner in order to achieve a desired advance of the contacting of the high-current contacts over the Ensure signal contacts of the connector.
  • the advance of the current contact can also be achieved by a different, in particular somewhat larger, length of the additional contact spring (s).
  • the rear wall 1 for example of an electronic computing device, is equipped with a plurality of (knife or pin) contact strips 11, which are inserted in parallel in parallel alignment next to one another from the top into the rear wall and whose contact pins pass through the rear wall on the underside in a manner not shown here, for example are wired in so-called winding technology.
  • the contact pins 16 of a contact track 11 are surrounded by a protective collar 2, the internal dimensions of which are adapted to the outline dimensions of a spring strip 6 (removed in the illustration) which, in a known manner, is equipped with a number of spring contacts (not shown) corresponding to the number of contact pins 16 is and at the same time one of a plurality of daughter cards 5 is used for mechanical mounting.
  • One or both walls of the protective collar 2 of the contact strip 11 are apart from a remaining section - the cam 7, which serves as a protection against rotation in a manner to be described later - on the narrow side 10 of the contact strip 11, so that a recess 9 is formed.
  • two conductor rails 3, 4 run along the narrow sides 10, which are freely accessible from the inside of the protective collar 2 via the cutout 9, that is to say can be electrically contacted in the area of the cutout. If only one power rail is required for the power supply of the daughter cards 5, then only one recess 9 or only one cam 7 can be provided on each contact strip 11, if necessary.
  • the busbars 3, 4 thus form in the region of the cutouts 9 the front end of the collar 2 of the contact strips 11.
  • the female connector 6 shown in FIG. 2 in an enlarged perspective partial view shows two projecting side walls 14, 15 in the region of the narrow side 10 'shown in the section engaging in the protective collar 2, which form a chamber open to the narrow side 10' into which Example shown two additional contact springs 8 are used, which contact the associated contact rail 3 or 4 via the recess 9.
  • two contact springs 8 which are connected directly and in one piece to one or more connection contact pin (s) 13, should generally be expedient for reliable contacting of the assigned busbar 3 or 4.
  • the distance between the two side walls 14, 15 of the chamber 12 corresponds to the width of the recess 9, while a remaining end wall section 18 corresponds approximately to the width of the cam 7.
  • the outer dimensions of the chamber walls 14, 15 in cooperation with the recess 9 and the remaining end wall section 18 in cooperation with the cam 7 form a "mix-up protection" or an anti-twist protection, so that it is always ensured that the respective daughter card 5 with the associated female connector 6th is inserted correctly into the associated contact strip 11 in each case.
  • the busbars 3, 4 can be attached by means of contact springs attached to the protective collar 2 or to the rear wall 1 or also to the housing of the device (not shown) in such a way that a slight height adjustment of the contact rails 3, 4, that is to say perpendicular to the plane of the rear wall 1 , and thus an adjustment of the contact lead advance of the power supply is possible.
  • the busbars 3, 4 can also be used in receiving slots 20 in the insulating body of the contact strips 11 and be fixed by one or two snap hooks 22 or 24, 26 molded directly onto the contact strips 11 by clipping them in (see FIGS. 3 and 4).
  • FIG. 5 ° Another solution for the slightly height-adjustable fixing of the busbar 3 or 4 is shown in FIG. 5 °.
  • the busbar 3 or 4 is likewise inserted into the front receiving slots 20 of the insulating body of the contact strip 11.
  • a metal bracket 28 is used to fix the busbar 3 or 4, which pulls the busbar 3 or 4 against a cam 30 molded onto the insulating body.
