Definitions

  • a telephonic coordinate switch formed of a matrix of reed relays of the magnetic-latching type and having each four coils on two cores.
  • the carrier grid of the matrix is formed of moulded rods arranged in two crossed webs. Each web comprises twin rods between the lines or rows of the reed relays proper (the sets of glass tubes). Each rod carries a line of coils that will be one of the four coils of the adjacent line or row of relays.
  • the relay cores and yokes are assembled in situ after rods with the coils are mounted in the switch frame.
  • the present invention relates to switching devices in the form of a matrix, of a type described in French Patent No. 1,393,336, dated Jan. 7, 1964, corresponding to United States patent application Ser. No. 423,226, filed Jan. 4, 1965, in the names of A. Regnier and F. Silerrne, and more especially in the first addition, No. 85,512, dated Jan. 17, 1964, to that patent corresponding to United States patent application Ser. No. 425,010, filed Jan. 12, 1965, in the names of A. Regnier and F. Silerme.
  • This type of device uses the well known four-coil relays having sealed magnetic contacts with several sealed contacts placed on one diagonal of a square, while the two magnetic cores, with their four coils, are placed at each end of the other diagonal.
  • the invention provides for simple and cheap construction of a device of this type and of a relay of the said type, and also a method of assembling this device and these relays.
  • the switching device is in the form of a matrix formed by two crossed webs of bars which are placed between the lines of relays according to the two coordinates of the matrix and which bear the relay coils on both sides in such a way that each one of the two cores of a relay goes through a coil borne by a bar from a first web and a coil borne by a bar from the other web; these two webs of bars being suitably mounted in an appropriate frame, preferably formed as.
  • the bars which separate the lines of relays each consist of two twin single bars; each single bar bears the coils of one line of relays.
  • all the single bars are identical; in a m n device the bars of one web only differ from those of the other by the number of their modules.
  • the bars are first equipped with windings on their coils, they are then set in the device frame, and the relays are assembled in loco between the bars by first passing the cores through the superimposed coils of the two webs of bars and then mounting the yokes on the cores.
  • the sealed contacts should preferably be assembled after the yokes. They are passed through lines of openings in both yokes of each relay. Finally the two crossed webs of the switching multiples are positioned.
  • Plates preferably lined with soft plastic foam, can be added to both sides of the device.
  • the coil connection system will preferably be the one described in the aforementioned Patent No. 1,393,336, or its second addition No. PV 38,110, Nov. 12, 1965, however some other connection system devised for four-coil relays may be employed. Elements associated to switching multiples or to the coil excitation system, such as decoupling diodes, can be'assembled around the frame and fixed to the ends of the bars or to the frame itself.
  • FIGURE 1 depicts the switching device according to the invention in perspective, and with parts cut out
  • FIGURE 2 is a cross-section, on a larger scale, of a relay assembled in the device, along the cores plane, and
  • FIGURES 3a and 3b show a single bar With its coils, respectively in overview and front view.
  • the device shown in the diagrams is designed in the form of a pluggable rack or drawer, as is usual in electronic equipment. It consists of a frame 1 in which two crossed webs of twin bars (2 and 3) are assembled. The twin bars are set out so as to form squares and the crosspoint relays, for example relay 4, are situated perpendicular to the squares. It will be noted that the two opposite sides of each square seen in overview aremade up of two bars of one web, and that the other two opposite sides are formed by two bars of the other Web.
  • Each twin bar comprises two single bars, e.g., bars 2 and 3, which are identical and placed back to back. If the device is square, 10 x 10 cross-points, for example, all the bars in both webs will be identical.
  • the bar ends can be fastened in the frame by means of any suitable devices, such as notches, lugs, etc. shaped in the frame and in the bars (see FIGURES 1, 3a and 3b). The insertion of the bars is facilitated, by the fact that they are flexible, being molded in plastic for example.
  • Each single bar (see FIGURES 3a and 3b) is formed initially with a series of empty coils, as shown at 5, which are preferably molded integrally with the bars. These empty coils are provided with energisation windings (see 6) before being assembled in the frame.
  • energisation windings see 6
  • all the coils of relays in a particular row must be energised in series.
  • all the windings borne by a single bar are linked together without brakes to form single energisation circuit in each line of corresponding coils along each single bar.
  • the connections of these circuits are suitably assembled in frame 1 and all. lead to one side of the frame 7 in FIGURE 1, where pluggable connecting strips such as 8 are situated.
  • the coils borne by the bars of both webs are superimposed on spools having a common axis, such as are shown at 5 and 9, so that each such pair of superimposed coils fits onto one of the magnetic cores of a relay. It is clear taking into consideration the four single bars, two in each Web, which form the square compartment around a relay, that the coils of a bar from one web, and of a bar from the other web, are superimposed in a corner of a square. The coils of the other bars of the two webs are superimposed in the opposite corner of the square, so that they can fit on the two magnetic cores of the relay (for example, relay 4) which is situated on a diagonal of the square.
  • relay for example, relay 4
  • the relays are assembled in the square compartments. These relays consist of three sealed magnetic contacts 10 (see FIGURE 2) which go through two yokes 11a, 11b, in the form of a bent yoke with two side lugs 12a, 12b. The ends of the two magnetic cores 13 are forced through these lugs, and the four coils 5-6 are thus the ends of the cores which extend beyond the coils. Finally tubes 10 of the sealed contacts are engaged through the two yokes (in which appropriate holes have been made) this being the last step in the assembling of the relays. The switching multiples wires are then assembled to form two crossed webs as in 14 and 15, and the pins of the sealed contacts are soldered onto these multiples. Two plates lined with sheets of plastic foam (not shown in the diagram) are provided in order to protect the relays and to help maintain their position in the frame. Plates should be assembled at both sides of frame 1 to form a closed rack.
  • a coordinate switch formed by a matrix of crosspoints in which each crosspoint includes a four-coil relay having two magnetic cores with two coils on each core and a magnetically driven contact device such as a set of reed relay glass tubes, said switch further including a carrier grid for the relays in the matrix, a grid structure formed by two crossed webs of rods between rows of relays, each rod supporting a line of coils with the axis of the coils at right angles to the grid, each coil supported by a web being aligned with a respective coil supported by the other web, each relay core being engaged through each such pair of aligned coils, and the contact device of each relay being set in a hole of the said grid structure.
  • a coordinate switch according to claim 1, wherein a further improvement comprises twin rods, each single rod being moulded integral with a line of coils one side thereof.
