Definitions

  • the present invention relates to a conductor connection for laminated printed circuit boards, consisting of a drawbar with screwed-in clamping screw and two contact plates arranged above and below the circuit board edge area and arranged in the drawbar.
  • the receiving edge region of the circuit board is provided with two slots, so that the pulling bracket of the conductor connection can be inserted here.
  • the contact plates are loosely inserted in the frame or cage-shaped contact bracket. The upper contact plate is acted upon by the clamping screw.
  • the contact plates are dimensioned with laterally protruding tongues so that these mechanically bridge the slots in the circuit board and thus forces which are perpendicular to the plane of the circuit board can be absorbed.
  • the two contact plates form loose individual parts that can easily be lost from the cage-like pull bracket, and the clamping screw itself can easily be removed from the pull bracket due to vibrations during transport.
  • connection on the circuit board and the fixing of the conductor in the connection are extremely problematic.
  • pull bracket must be in the slots of the PCB must be threaded, but moreover, the two contact plates must also be kept apart in order to cover the material area
  • the present invention has for its object to provide a conductor connection of the generic type which, on the other hand, is very easy to assemble and is characterized by good electrical conductivity between the top side of the printed circuit board and the underside of the printed circuit board.
  • the solution according to the invention is that the two contact plates are mechanically and electrically conductive at their edges facing away from the printed circuit board are connected to each other to a pressure piece, which in turn is freely rotatably connected to the clamping screw.
  • the two contact plates for receiving the printed circuit board are at a distance that is ready for reception. They are captive and together with the clamping screw form an overall captive unit, since the clamping screw itself can no longer be lost.
  • the pull bracket By turning the clamping screw into the open position, the pull bracket also reaches the open position and is readily ready to receive the conductor to be connected, because the lower contact plate can no longer fall off as part of the pressure piece.
  • the connection of the two contact plates to the pressure piece also ensures an excellent electrical connection, which is always to be adequately dimensioned in the line cross section, between the two contact plates and thus between the conductor tracks on the upper side and the lower side of the printed circuit board.
  • the pressure piece is bent from a stamped part containing the two contact plates and a connecting web. The pressure piece is thus also easy to manufacture.
  • a connecting tab is arranged on the upper contact plate of the pressure piece, in which a snap-in receptacle for the clamping screw, which is expediently provided with a corresponding screwing, is provided.
  • This connecting tab is advantageously formed on the stamped part.
  • the distance between the two contact plates of the pressure piece is dimensioned and the pressure piece is made of such a material that it can be resiliently placed onto the printed circuit board in a predetermined printed circuit board thickness range.
  • the provider of the circuit board and the connection can already slide the connector onto the circuit board and in its open position, i.e. ready to receive the electrical conductor to be connected, the provider is offered.
  • a convenient assembly contributes to the fact that the opening and insertion direction of the snap-in receptacle for the clamping screw is at an angle of 90 ° to the opening and insertion direction of the contact plates with respect to the printed circuit board. In this way, during assembly, the pressure piece can be inserted in a simple manner from the one side of the pull bracket and locked with the clamping screw, while then being pushed onto the printed circuit board on the other side of the connection thus assembled.
  • the drawbar in the case of the conductor connection in the case of unslotted areas of the printed circuit board edge, has a receiving slot on its side facing the printed circuit board. Thanks to this configuration, such a conductor connection can also be connected at any time to the edge regions of an unslotted printed circuit board at all desired locations.
  • a separate conductor connection piece is provided in the tension bracket outside the pressure piece. This configuration in particular enables the manufacturer and supplier of the printed circuit boards and the connecting pieces to carry out a fully functional pre-assembly of the printed circuit boards.
  • connections are fixed at the factory with a predetermined torque and thus without the risk of destruction on the printed circuit board at the predetermined points by means of the clamping screw connected to the pressure piece. Improper attachments to the user are also switched off. With this configuration, the user no longer has to worry about the attachment of the connection to the circuit board itself. He simply puts his conductor to be connected in the area of the separate additional conductor connection piece and then only fixes the conductor in the tension bracket.
  • the conductor connection has a cage-like closed at the four corners 1, into which a clamping screw 2 is screwed on the top.
  • the laminated printed circuit board 3 has two slots 4 in its edge area for receiving the conductor connection, into which the pull bracket can be inserted.
  • the conductor connection also has two contact plates 5 and 6, which are mechanically and electrically connected to one another to form an integral pressure piece 7. For this purpose, they are connected at their edge area facing away from the printed circuit board via a connecting web 8.
  • the pressure piece 7 is also freely rotatable locked to the lower end of the clamping screw 2, for which purpose the clamping screw 2 has a recess 9 at its lower end and for which purpose the pressure piece 7 has a connecting tab 10 in which a latching opening 11 for receiving the lower end of the clamping screw 2 is provided.
  • the connecting tab 10 is expediently formed in one piece with the one free edge area of the lower contact plate 6.
  • the entire pressure piece 7 including the connecting tab 10 is, for example, a one-piece stamped part, which is then bent according to its final shape.
  • the opening and insertion direction of the snap-in receptacle 11 in the connecting lug 10 is at an angle of 90 ° to the opening and insertion direction of the two contact plates 5 and 6 with respect to the printed circuit board 3.
  • the pressure piece 7 can thus be easily inserted into the pull bracket from one side 1 inserted and locked here with the lower end of the clamping screw 2 and is then ready for insertion on the other side with respect to the circuit board. This is indicated by arrows in Figure 1.
  • the distance between the two contact plates 5 and 6 is dimensioned from one another and such a material with good electrical conductivity properties and sufficient spring properties, such as brass, is chosen for the pressure piece that the conductor connection is resiliently clamped overall in the sense of the pre-assembly the corresponding edge area of the printed circuit board 3 can be pushed on and is here also held sufficiently firmly on the printed circuit board by the resilient clamping action of the two contact plates 5 and 6.
  • the two contact plates 5 and 6 have protruding lateral areas so far that they mechanically bridge the slots 4 on the top and bottom of the circuit board after being pushed onto the circuit board.
  • this conductor connection can also be pushed onto the printed circuit board or preassembled on it in the predetermined open position, as shown in FIG. 1.
  • the surfaces of the contact plates 5 and 6 facing the circuit board 3 can be provided with latching cams (not shown) for which latching recesses are provided in the circuit board.
  • the pressure piece 7, with the same construction, is locked in a freely rotatable manner with the clamping screw 2, with the contact plates 5 and 6 and the connection Tab 10 is arranged in a pull bracket 1 ', which in turn additionally has a receiving slot 12 on the side facing the printed circuit board 3, so that this conductor connection for sliding onto the printed circuit board is no longer dependent on slots being provided at a corresponding point in the printed circuit board.
  • a pull bracket 1 '' is provided which, as in the embodiment of Figure 3, on the side facing the printed circuit board 3 has a receiving slot 12 for pushing the conductor connection onto the edge of an unslotted printed circuit board and in the latter Receiving area of the circuit board again the pressure piece 7 with the contact plates 5 and 6 and the connecting tab 10 is provided and is rotatably locked with the clamping screw 2.
  • the clamping screw 2 only serves to fix the conductor connection on the printed circuit board, but no longer to simultaneously fix the conductor to be connected to the pulling bracket 1 ".
  • This pulling bracket 1" has a separate conductor connecting piece outside its area which receives the pressure piece 7, For example, in the form of a further clamping screw 13, which carries a clamping bracket 14, so that here, based on the circuit board in the rear area, the conductor to be connected can be determined separately, specifically when the conductor connection as such via the clamping screw 2 is already on the printed circuit board 3 is finally assembled.
  • the contact plates 5 and 6 of the pressure piece 7 can be provided with locking teeth on their surfaces facing the circuit board, which dig into the conductor tracks when the conductor is connected, and which also already can cause grooves to favor contact when the connection is pushed onto the circuit board in the conductor tracks.
