Definitions

  • the invention relates to a device for connecting cables to the connections of printed circuit boards which carry electronic components and are arranged in magazines parallel to one another.
  • Printed circuit boards with electrical or electronic components are often connected to a backplane circuit board on which the conductor tracks for the mutual connection of the connections of the individual circuit boards are arranged. Lines or cables to external units or devices also extend from the backplane wiring board.
  • the backplane, the z. B. is formed in multilayer technology, can be provided with press-in pins, which form contacts with metallized holes in the backplane circuit board if necessary.
  • the press-in pins protrude beyond the printed circuit board levels on both sides.
  • frames surround parallel rows of press-fit pins, which are arranged at a distance from one another which is defined for plug connectors. The frames serve as a guide for female connectors that are connected to the circuit boards.
  • spacers are arranged on the side of the backplane printed circuit board facing away from the printed circuit boards, on each of which further frames are fastened, which surround the ends of the press-in pins projecting beyond the spacers.
  • Wire-wrap connections can be arranged on the sections of the press-in pins running between the backplane and the underside of the frame.
  • the frames form guides for plug elements which are pushed onto the ends of the press-in pins.
  • the effort for connecting the circuit boards carrying the electronic components to cables is relatively great in the arrangement described above.
  • the frames provided for the connection of the cable connectors can mainly only be used together with the press-in pins in the backplane.
  • the invention has for its object to develop a device for connecting cables to printed circuit boards equipped with electronic components, which enables the connection of cables to the front and / or the rear sides of the printed circuit boards with as little effort as possible.
  • the object is achieved by the measures described in claim 1.
  • the guide frames placed on the backplane wiring board are empty housings for male connectors. Therefore, commercially available parts are used for the connection of the printed circuit boards to the rear wall printed circuit board and the cable connectors, which parts are also used to a large extent for the production of connections. A particularly economical solution can thus be achieved. If the external connections possible on a narrow side of the circuit board are not sufficient, the front can also be provided with a male connector, which replaces the usual front plates in conjunction with a guide frame. The guide frame is screwed onto the horizontal mounting rails.
  • the guide frame which surrounds the male connector on the front of the respective circuit board, is a part that may not be as versatile as the other components for making the connections from the circuit boards to the backplane circuit board or to the cable connectors. Since only commercially available, inexpensive male connectors and empty housings are required for the backplane in order to provide the possibility of connecting cables, it is expedient that To equip backplane circuit boards at all circuit board locations with these components, even if not all circuit board locations in the respective device are occupied with circuit boards from the start. The effort that results in equipping all circuit board spaces with connecting elements is significantly less than the effort required for subsequent expansion if the device is to be expanded and additional circuit boards have to be inserted into the existing empty spaces.
  • the spring strips which can be inserted into the guide frame are designed with cutting elements for the connection of wires using insulation displacement technology.
  • the individual wires of the round conductor cables to be connected can be connected efficiently and quickly using the cable connectors described above. It is possible to connect incoming and outgoing lines using, for example, 64-pin cable connectors.
  • a backplane 1 contains parallel rows of holes 2 arranged a predetermined distance apart. The distance corresponds to the division of pins 3 of a knife bar 4.
  • the knives bar 4 contains parallel rows of straight pins 3, one of which is shown in detail in the drawing.
  • Holes 5 are provided at both ends of the male connector 4 and run parallel to the pins 3. By means of screws 6 inserted into the holes, the male connector 4 is fastened to the backplane 1. In the assembled state, the pins 3 protrude beyond the surface of the backplane 1.
  • Printed circuit boards 7, which carry electrical or electronic components, are inserted into the male connector 4 with female connectors 8, each of which is attached to the rear side of the male connector 4.
  • the ends of the pins 3 protruding beyond the surface of the backplane 1 are surrounded in parallel rows by a guide frame 9 for male connectors.
  • the guide frames 9 have holes 10 through which the pins 3 protrude.
  • the screws 6 and nuts (not shown in more detail) serve at the same time for fastening the guide frame 9 to the rear wall circuit board 1.
  • the guide frames 9 have on their sides elongated projections 11 with recesses 12, into which locking hooks 13 with their fork-shaped ends 14 are inserted.
  • the guide frame 9 with the ends of the pins 3 projecting beyond the holes 10 is combined with a spring strip 15 which has cutting elements 16 projecting to one side for the connection of wires using insulation displacement technology.
  • a wire guide member 17 is attached, which contains channels, not shown, which end at the locations of the cutting elements 16.
  • the free ends of the wires 18 of a cable 19 are inserted into the channels and can be laid to external units or devices.
  • the female connector 15 contains recesses 20 in the long sides.
  • Two cable housing half-shells 21, 22 have projections 23 which engage in the recesses 20 when the cable housing half-shells 21, 22 are placed against one another above the female connector 15 and the wire guide element 17.
  • latching elements of the housing half-shells which are not specified, engage in one another and bring about a firm connection between the housing half-shells 21, 22 and the female connector 15 or the wire guide element 17.
  • recesses 24 are provided for the passage of the cables 19. Furthermore, there are clamping elements 25 for the cables 19 in the housing half-shells 21, 22.
  • a number of male connectors 4 and guide frame 9 corresponding to the number of printed circuit board locations is fastened on the rear wall circuit board 1. For the sake of clarity, these parts are only shown once in FIG. 1. If necessary, the circuit boards 7 are inserted into the corresponding circuit board slots. Connections between pins 3 of different male connectors 4 can be produced via the plated-through holes 2, which are connected to conductor tracks of the backplane circuit board, not shown. A multilayer board may be used as the backplane.
  • the housing half-shells 21, 22 are provided with lateral projections 25, which have recesses for receiving the ends of the locking hooks 13, which are held with locking lugs 26.
  • the male connector 4 and the guide frame 9 are commercially available, widely used components that are not only used for backplane boards. These components can be obtained inexpensively. Therefore, the device for connecting the cables to the circuit boards 7 can be produced economically.
  • Knife strips 28 can be fastened to the front end faces 27 if necessary if the number of connections on the rear end face 29 is not sufficient.
  • the male connector 28 is surrounded by a guide frame 30, the dimensions of which are adapted to the front plates 31 of printed circuit boards which are usually fastened to rails 32.
  • the guide frame 30 contains at its ends 33, 34 recesses 35 for receiving inserts with which it is screwed onto the rails 32.
  • the attachment can be carried out by means of screws and threaded strips, which are inserted into grooves in the rails 32, which are not described in more detail.
  • the recesses 35 are preferably elongated and serve to receive an elastic intermediate piece 36, which is connected to the threaded strip 38 by means of the screws 37.
  • the guide frame 30 surrounds the male connector 28, the male pins 39 of which engage in the springs of a female connector 40 which is connected to the male connector 28.
  • the structure of the female connector 40 corresponds to the female connector 15. The same elements on the female connectors 15 and 40 have therefore been given the same reference numbers.
  • a wire guide element 41 is placed on the female connector 40, the structure of which corresponds to that of the wire guide element 17.
  • the wire guide element 41 contains channels into which the free ends of wires 43 are inserted.
  • the wires 43 run to the point at which they are connected to the cutting elements 16 using insulation displacement technology.
  • the wires belong to a cable 44 which runs to external units or to other connection points on the front or the back of the printed circuit boards 7.
  • the female connector 40 and the wire guide element 41 are held in their combined state by two housing half-shells 45, 46.
  • the housing half-shells 45, 46 correspond in construction to the housing half-shells 21, 22. Locking hooks 13, the fork-shaped ends of which engage in recesses 48 of the guide frame 30, can be inserted into recesses 47 in the lateral projections of the housing half-shells 45, 46.
