Definitions

  • the invention relates to a releasable, electrically conductive cable connection, in particular for flat cables with contact surfaces arranged on a surface, with a shaft arranged adjacent to a cable insertion opening and rotatable into an active position by means of an actuating lever, a pressure element arranged on the shaft exerting a compressive force on the contact surfaces of the cable exercises.
  • Detachable cable connections in particular for flexible line plug connections between circuit units, usually consist of contact pins or springs which are inserted into corresponding spring-loaded sockets.
  • the dimensions of the springs in the sockets are kept somewhat smaller than the contact pins or springs are thick.
  • the invention has for its object to provide a detachable electrically conductive cable connection, in particular for flat cables, in which the connections can be made without effort, even if there is a larger number of contact connections to be made simultaneously.
  • This object has been achieved in a device of the type described above by the embodiment mentioned in claim 1.
  • the invention is based on a cable connection device as described in the IBM Technical Disclosure Bulletin, Volume 7, No. 9, page 742 is known. There, a cable insertion opening is provided, into which a flat cable that can be detachably connected to a line pattern is inserted, specifically between the line pattern and a spiral spring element. To establish the contact connection, an operating lever is pivoted, whereby the spiral spring is rotated and its effective force is increased.
  • connection according to the invention has the disadvantage that the cable is not inserted without resistance.
  • connection according to the invention has the advantage that cables with any number of contact surfaces can also be inserted without resistance and only then does the force for establishing the contact connection become effective.
  • the plug-in device according to the invention is therefore also particularly suitable for maintenance and replacement work “in the field”, that is to say on the machine at the place of use in the context of service work, troubleshooting and elimination, and the like. ⁇ ., where flat cables are used.
  • the connection according to the invention can also be used with great advantage for diagnostic device and measuring device connections and similar applications.
  • the device shown in the drawings consists of a housing 10, preferably made of plastic, which forms a chamber 11 in the lower region and in the upper region of which there is an opening 12 which is connected to the chamber 11. Furthermore, there is an insertion opening 13 for a lower flat cable 19 on one side of the housing 10 and an insertion opening 14 for an upper flat cable 20 on the other side, both insertion openings 13, 14 leading into the chamber 11.
  • a cam roller 16 is mounted eccentrically on a rotatable shaft 15 in the upper region of the housing 10 and extends over the entire length of the opening 12.
  • the cam roller 16 is provided with a jacket 17 made of synthetic rubber, the thickness of which is in the range from 0.5 to 1 .5 mm is selected, depending on the design of the cables to be connected.
  • the eccentric cam roller 16 can be rotated by means of an actuating lever 18 connected to the shaft 15.
  • the device described above is used for the electrical connection of the two flat cables 19 and 20.
  • Such flat cables are produced in different thicknesses and preferably consist of a polymeric material which is copper-coated and subsequently etched in order to form printed circuit conductors 21 in a specific pattern receive. These are connected to a row of gold contacts 22 which are applied to the surface of the flat cable near the end.
  • the gold contacts 22 are usually about 0.37 to 0.5 mm wide and 0.75 to 1.8 mm long.
  • the thickness of the flat cable 19, 20 is usually in the range of 0.25 to 0.35 mm, so that due to their elasticity they are particularly suitable for connecting printed circuit boards, e.g. As such printed circuit boards, the different patterns of the input and A have usgangs gleiche. They are also used to connect planar printed circuit boards to the corresponding contacts in the computer frame in which they are used.
  • Fig. 2 which shows the parts of Fig. 1 for clarification in about three times the starting position of the actuating lever 18 is shown in dashed lines, in which the cam roller 16 is in its "open" upper position, as also drawn in dashed lines.
  • the flat cable 19 is first inserted into the insertion opening 13 as far as possible, with the gold contacts 22 facing upwards.
  • the flat cable 20 is then inserted into the insertion opening 14 on the opposite side of the device, in such a way that the gold contacts 22 lie on the underside. Here, it slides with the gold contacts 22 to the corresponding contacts on the surface of the flat cable 19.
  • the flat cable 20 is pushed as far as possible in the chamber 11, wherein the strength in F. 2 marked with 23, shown in dashed lines.
  • the gold contacts 22 of both flat cables 19, 20 are now covered.
  • the actuating lever 18 is actuated clockwise, so that the cam roller 16 exerts increasing pressure on the top of the flat cable 20 and the gold contacts 22, which are opposed in pairs, are pressed more and more against one another.
  • the flat cable 20 executes a horizontal movement to the left, so that between the gold contact pairs 22 a thrust movement is generated, which results in both a cleaning effect and a particularly intimate contact of the contact surfaces.
  • the actuation lever 18 After actuation of the actuation lever 18 by an angle of 180 ° , it abuts a stop surface 24 of the housing 10, and now the contact pairs have reached their final position in relation to one another in the contact region 25.
  • the horizontal pushing movement of the flat cable 20 is approximately 0.75 to 1.25 mm.
  • the operating lever 18 is pivoted counterclockwise by 180 ° into its starting position, as a result of which the two flat cables 19 and 20 are released and can be pulled out as a result of the cam roller 16 being lifted off.
  • the jacket 17 on the cam roller 16 is able to compensate for certain differences in thickness in the contact surface area and thus ensures a uniform pressure force. Furthermore, the contact transition between the two flat cables 19, 20 is influenced extremely favorably by the pushing movement between the contact surfaces in the course of the closing movement of the actuating lever 18.
