Definitions

  • the present invention relates to a means for attaching on the spring assembly portion of a relay yoke a printed circuit card having one side provided with soldering tags which correspond to position and shape to the soldering tags of the relay spring assembly.
  • relays In the electrical circuits comprised in the relay racks of a telephone exchange there are, in addition to the relays, many other components like resistors, capacitors and semi-conductors of various kinds.
  • the relays are, however, the largest and heaviest components, and so the mechanical construction of the relay racks has been made with regard to the relays.
  • cooperating relays have been brought together in so called relay sets comprising one or several strips on which the relays are mounted. Via a relay set cable the relays are connected to each other and to a terminal means belonging to the relay set.
  • Small components, like resistors, capacitors, semi-conductors etc. which are circuitwise included in a relay set are often to a large extent soldered in their connecting wires on the rear or connection side of the relay set.
  • An object of the present invention is to increase the number of alternatives for placing small components in relay sets by making possible, in a simple and space saving way, the placing of printed circuit cards in idle spring assembly places on relays comprised in the sets.
  • This is according to the invention made possible by an arrangement which comprises a mainly U- shaped clamp whose web is in a way known per se attached on the yoke by means of spring or screw devices and a printed circuit card is kept in place in the clamp by means of protrusions or lugs in the card which fit into openings in the web and a first branch of the clamp while a second branch of the clamp has a hook-shaped notch along one of its sides which grasps the card side remote from the web and presses the card against the web with the part of the card which is stretching beyond the clamp.
  • FIG. 1 shows in perspective a means for attachment of a printed circuit card and in which FIG. 2 shows the instant of the fitting of the printed circuit card into the means for attachment.
  • reference 1 denotes a printed circuit card inserted in a means of attachment consisting of a U-shaped clamp comprising a web 2, a first branch 3 and a second branch 4, which second branch, by means of a notch along one of its long sides, is shaped as a hook.
  • the printed circuit card is kept in place through the agency of protrusions or lugs 5, 6 and 7, which fit into corresponding openings 8, 9 and 10 (FIG. 2) in the web 2 and the first branch 3 of the clamp.
  • the second branch 4 shaped as a hook, grasps the card side remote from the web of the clamp and presses the card against the web 2.
  • the web of the clamp is, in a way known per se, by means of spring or screw devices attached in a spring assembly place of a relay yoke 11.
  • a part 12 of the card, which extends beyond the clamp, is provided with soldering tags 15 which as to position and shape correspond to the soldering tags of a relay provided with soldering tags spring assembly.
  • Components (not shown) mounted on the card are, via the printed circuits, (not shown) of the card, connected to soldering tags 15, to which the relay set cable is connected in the same manner as to a relay spring assembly.
  • the printed circuit card may, as shown in FIG.
  • the first branch 3 of the clamp by two bends having been made to follow the contour of the card.
  • Another measure which has been taken for maximally using the space of the spring assembly is to make the card as wide as possible and to provide it with a stair shaped notch 13, where the second branch, shaped as a hook 4, grasps the card.
  • FIG. 2 show the instant of the fitting of the printed circuit card into the clamp, at which time the card is placed in the clamp with the hook 4 in engagement with the bottom of the notch 13.
  • the next instant concerns the fitting of the lugs 5, 6 and 7 into the corresponding openings 8, 9 and 10 of the clamp.
  • the lug 5 is then at first fitted into the opening 8 and the card is conveyed in the direction of the first branch 3, whereby the hook 4 will bear on the vertical side of the stair shaped shoulder 14 and be bent in the direction of motion.
  • one of the branches has been shaped as a hook, it has furthermore become possible to extend the part of the card which is provided with soldering tags beyond the clamp, whereby at the connection of the relay set cable the card may be handled in the same manner as a relay spring assembly which is of importance with regard to manufacturing,
  • the shape of the clamp and the card may be varied within the scope of the invention.
  • a component mounting means attached to a relay yoke at the spring assembly position thereof comprising: A substantially rectangular printed circuit card having at least one lug extending from one longer side thereof and one lug extending from one shorter side thereof, a plurality of soldering tags con nected to the other shorter side of said printed circuit card, a substantially U-shaped clamp for holding said printed circuit card, said clamp having a web and first and second branches, said web and first branch being provided with openings for accepting said lugs in such a way that said one longer side of said printed circuit card is adjacent said web and said one shorter side of said printed circuit card is adjacent said first branch, said second branch being notched to provide a hook for grasping a portion of the edge of the other longer side of said printed circuit card, the length of said printed circuit card being greater than the spacing between said branches so that said soldering tags extend beyond said clamp, and means for attaching said web to the relay yoke.
