Definitions

  • the invention relates to a connector assembly of the type mentioned in the preamble of claim 1.
  • the connections are no longer side by side on the surface for example, the edge of a circuit board, arranged, but lined up perpendicular to it. There is generally much more space in the direction perpendicular to the edge diaphragm, so that the number of connections can be increased almost as desired in this way.
  • the latter is still inserted through an opening formed in the edge panel and inserted into the connector housing until the connector contacts and the mating contacts are opposite one another, whereupon the connector contacts and mating contacts are brought into contact with one another by rotating the mating connector will.
  • the connector housing has approximately the shape of an elongated box standing at right angles to the edge panel with a like or on the circuit board. lying on the bottom side and two side walls arranged perpendicular to it, that on the inside of the side walls each perpendicular to the bottom side, with contact lamellae provided with openings protruding through openings in the bottom side, and that the mating connector has approximately a hollow rectangular cross-section, the long sides of the rectangle have approximately the width of the connector housing and are arranged on the narrow sides in each case outwardly bent contact lamellae which can be connected via lead-through openings to the wires of the cable arranged inside the mating connector.
  • the plug housing is placed on the circuit board in such a way that it can be connected to the edge panel in a manner to be described later, the contact feet projecting downwards being able to be soldered to the printed circuit board in a manner known per se.
  • the mating connector can assume two angular positions with respect to the connector housing, namely an insertion position, which allows a longitudinal displacement of the mating connector in the connector housing, as well as a contact position rotated by 90 °, the mating contacts arranged on the narrow sides of the connector having the mating contacts on the side walls of the connector Arranged connector housing come in electrically conductive contact, as will be described in more detail below.
  • the cores of the cable arranged in the interior of the mating connector are guided and connected to the mating contacts located on the outside of the mating connector via respectively assigned through openings.
  • insulating webs are provided between them. These are designed so that they come into mutual contact when the mating connector is in contact; in that the insulating webs are each provided with interlocking, complementary profiles on their end faces which come into contact with one another, they simultaneously fulfill a locking function, i.e. they prevent axial displacement of the mating connector in the connector housing.
  • protruding coding projections are arranged which, when the mating connector is inserted into the connector housing in the correct position, engage in longitudinal grooves formed on the inside of this connector housing and extending in the direction of insertion.
  • wall recesses are formed at the rear end of the plug housing in the plugging direction, in which the coding projections are received in its contact position when the mating plug is turned.
  • a certain arrangement of these wall recesses can therefore be achieved that the mating connector can only be rotated in a certain direction, so that incorrect couplings are excluded.
  • the contact lamellae forming the plug contacts are approximately hook-shaped with a main part tapering downward in a contact foot as well as resilient contact tongues which bend downward and project parallel to the main part.
  • the main part is used for the secure storage of the contact lamellae in the connector housing and is secured for this purpose, for example, by means of a tongue which is formed against it and rests against a locking surface on the connector housing, and by means of projections arranged on the insulating webs of the connector housing, to prevent the main part from lifting off.
  • the downwardly bent contact tongues are in a manner known per se or the like with convex contact knobs. equipped by the one unique contact line or a contact point is defined.
  • the mating connector is divided according to a feature of the invention in the longitudinal direction so that there are two substantially L-shaped locking profiles, the cross section of which is composed of a longitudinal side and an adjacent narrow side of the rectangular cross section of the mating connector.
  • the inside of the mating connector is easily accessible, so that the cable can be laid inside and the individual wires can be fed to the through openings.
  • the contact blades forming the mating contacts are bent approximately L-shaped , wherein the short base leg is located on the outside of the sides of the transom profile formed by the narrow sides of the rectangular cross section and the long leg is assigned to the sides of the transom profile formed by the long sides of the rectangular cross section.
  • the long legs of the mating contacts are preferably designed at the end as fork-shaped cutting contacts.
  • the sides of each transom profile formed by the long sides of the rectangular cross-section are then designed as cable strips that can be detached from the transom profile the wire ends are inserted through the lead-through openings of the cable strips and these are pushed onto the ends of the mating contacts provided with the cutting contacts, the contact between the wires and the mating contacts automatically being established in a manner known per se. On the exit side of the The protruding wire ends can easily be cut off.
  • the two locking profiles are joined together after the cable assembly and are preferably connected to one another by an end flange which can be plugged onto the front end face in the direction of insertion of the locking bar and can be positively connected to both locking profiles, and by a handle piece which can be attached to an extension formed on the opposite end of the locking bar.
  • This handle protrudes in the coupled state of the mating connector beyond the front of the bezel and is designed so that it is easy to handle.
  • the handle is preferably divided in a plane parallel to the axis of rotation of the mating connector, the extension of the bolt and the two parts of the handle are each provided with complementary, interlocking profiles which, after locking the two parts of the handle, provide a firm connection between the handle and ensure the bolt in the axial direction and in the circumferential direction.
  • the mating connector can furthermore be provided according to the invention with a guide shaft which cooperates with guide surfaces in a corresponding housing area intended for receiving this guide shaft and prevents, for example, tilting of the mating connector during the insertion movement or premature rotation of the same before the complete insertion.
  • this is, for example, with elastic hook elements which can be snapped into receptacles in the printed circuit board and with against the edge panel provided adjacent flange elements that allow a screw connection.
  • the handle is preferably made of a metallic material, for example aluminum, and has means for the electrically conductive connection of a shield of the cable.
