Definitions

  • the invention relates to an electrical circuit arrangement and an appliance which is provided with such circuit arrangement.
  • the invention is particularly intended for telecommunications appliances.
  • the electrical circuit arrangement according to the invention and the device which is provided with such circuit arrangement are characterized in that the electrical conductors are resilient wires, which are round or angular in cross section, and are firmly connected to an insulating support at least at one point of the line, and guided in at least one nose and at least one groove or in at least two oppositely directed noses of the insulating support, the conductor being guided on the surface of the insulating support or in an elongated recess in the insulating support.
  • the electrical conductor are, in a development of the invention, wires which are bare throughout or in a part of their length.
  • the conductor is firmly connected to the insulating support by a screw.
  • a firm con nection of the conductor to the insulating support is established by rectangular insulating walls, which are at right angles to the insulating support and closed on three sides. The walls serve to receive a square nut and have at least one through aperture for the conductor.
  • the insulating support is provided at the center of the space enclosed by the insulating walls with a through aperture for the connecting screw. Apertures are provided for receiving the lugs of a cover plate and a fixing bolt. The bent, preferably curved, end of the conductor is clamped by the bolt between the cover plate and the nut and is firmly connected'by the lugs to the insulating support.
  • the firm connection of the conductor to the insulating support may be established in that the conductor is threaded into at least two holes of the insulating support. That end of the conductor which is remote from the line is preferably used for the connection to the connecting leads of the circuit arrangement by soldering, clampingor plugging.
  • the circuit arrangement according to the invention can easily be installed and enables the use of the conductors as contact members. Further according to the invention a second, similar conductor is provided, which crosses the conductor substantially at right angles and which constitutes the second contact member and is moved by an actuating member, e.g., a key member.
  • an actuating member e.g., a key member.
  • the bare conducting wire and a second, similar conducting wire extend parallel to each other and these two bare conducting wires form one part of a contact whereas a third conductor, which is substantially at right angles thereto, fonns the second part of the contact.
  • the third conductor may be similar to the first and second conductors or the third conductor is characterized in that it is a freely movable shorting member, preferably of wire, which is secured to a contact-actuating member, e.g., a key member.
  • the conductor 2 is secured to the insulating support 1.
  • the circuit arrangement according to the invention is characterized by four requirements: The resilient conductor 2, the fixation of this resilient conductor 2 to the insulating support 1 at least at one point 3 of the resilient conductor 2, the insertion into at least one nose 5 of the insulating support 1 and the insertion into at least one groove 4 of the insulating support 1.
  • a groove and nose two oppositely directed noses 17, 18 may be used.
  • the conductor 2 may be round or angular, e.g., rectangular, in cross section.
  • the conductor 2 need not lie in a single plane. Where a large number of conductors are used, the conductor must be bent in the form of steps or must be laterally shaped in a horizontal plane so as to provide space for other conductors in the same plane.
  • the invention is not restricted to the use of only one groove or one nose or to two oppositely directed noses for one conductor. A plurality of noses and grooves may be used.
  • the directions of that portion of the noses which is parallel to the insulating support may differ.
  • the inside surfaces of the noses, particularly that portion which is parallel" to the insulating support may include an angle with the insulating support or have a curved surface. For instance, it may provide more space close to that portion which is at right angles to the insulating support than at the portion which is remote therefrom.
  • the grooves too may be wider at the bottom than at the top.
  • the groove and nose will protrude from the same. If the conductor is guided in an elongated recess such as that at 20 in the insulting support, the groove and nose 17 will be within the elongated recess.
  • the latter embodiment is particu larly suitable for a stacking of insulating supports.
  • the invention is not restricted to the use of straight guides for the noses and grooves.
  • the grooves and noses may be angled, i.e., two noses or grooves having different directions may be combined in one element.
  • the conductors may be bare wires throughout their length or may be bare only in part of their length, e. g., at the ends or where they are connected to other conductors.
  • the fixation of the conductor 2 need not be effected at the end.
  • the conductor 2 may be fixed anywhere in the line so that the ends are not fixed.
  • the conductor may be connected to the insulating support at a plurality of points of the line.
  • the conductor 2 is connected tat its end 3 by means of a bolt 12, which is threaded into a nut 10, which is located in the space defined by the walls 6 and 7 by the cover plate 11 having lugs 15 and I6.
  • the lugs are passed through the slots 13 and 14 and reversely bent on the underside of the insulating support 1.
  • a U-shaped end of the conductor 2 is previously inserted between the nut'l0 and the cover plate 11.
  • the conductor 2 is threaded through holes in the insulating support I.
  • the conductor 2 is bent at right angles and passed through the insulating support I, on the underside of which the wire is laterally bent to extend parallel to the line or at an angle, e.g., a right angle, thereto and in the plane of the underside and is then returned, at right angles, to that surface of the insulating support which is visible in the drawing.
  • these free ends are used for connection to the outside connections when the conductor has been threaded.
  • This connection may be established, e.g., by soldering, clamping or plugging.
  • conductors also as contact members.
  • Such contacts according to the invention are preferably established by a crosswise arrangement of the conductors, which are placed or guided according to the above-mentioned features of the invention.
  • These conductors are connected to or separated from each other by keys.
  • a plurality of conductors may extend parallel to each other. The number of parallel conductors is not restricted to two.
  • Two parallel conductors may be short-circuited by a crossing wire, which is connected to the key member, and may be opened after the shorting.
