Definitions

  • This invention relates to multiplexing circuits and is particularly concerned with the mounting and connection of diodes in such circuits.
  • the invention will be described in connection with multiplexing arrangements for lamps used in gaming or amusement machines, but it will be understood that it is applicable to multiplexing arrangements for small panel-mounted lamps in general.
  • Lamp holders and other illuminated components such as push buttons which have been designed specifically for multiplexing operation incorporate the diode internally as part of the component.
  • many of the lamp holders and illuminated components used in amusement machines have not been designed specifically for multiplexing operation and a separate diode has to be fitted externally, involving a relatively expensive soldering operation.
  • a diode is included in a self-contained adapter unit provided with male and female terminal arrangements, one lead of the diode extending to the female terminal socket which is designed to accept one of the male terminals of the lamp holder or other component and the other lead being connected to the male terminal to provide a connection point to an external circuit.
  • a diode can be connected in series circuit with a small lamp or other illuminated component merely by fitting it in position to the male terminal of the lamp and without the need for any separate soldering operation.
  • the diode is fitted in the adapter unit in such a way that the connections to the diode leads are dry connections, that is to say frictional or pressure connections, thereby further simplifying the assembly.
  • the body of the unit may be formed as a plastics moulding, in which one of the diode leads extends along the side of a recess in the body defining a socket for the reception of a male terminal of the lamp or other component and the other lead extends along the side of a passage within which the male terminal of the unit is a force fit.
  • the male terminal and the passage within which it fits may be formed with complementary inter-fitting portions which are brought into engagement when the terminal is forced into position, and may have a portion which inter-fits with part of the moulding so as to hold the male terminal in position.
  • the body 1 of the adapter unit is formed as a plastics moulding having a recess 2 for the reception of a diode 3.
  • One diode lead 4 extends in line with the body of the diode through a corresponding passage in the moulding, having been cut to length so that it reaches the right hand end of the body 1, as seen in Figure 1.
  • the other lead 5 is bent into a U-configuration prior to fitting into the body 1 and extends along a second recess 6 which is separated from the recess 2 by a partition 7.
  • the free end of the lead 5 extends into a further recess 8 opening from the right hand end of the body 1, and after the diode has been fitted, the end portion of the lead 5 is bent upwardly at 12 so as to fit against a shoulder 13 on the moulding and thus prevent withdrawal of the diode 3 to the left.
  • the lead 4 is held firmly within its passage by insertion of the male terminal 14 of the adapter. This is in the form of a flat tab which is inserted into a correspondingly shaped slot opening from the right hand end of the moulding 1, within which, in conjunction with the lead 4, it forms a force fit.
  • the tab 14 may, for example, be a standard 250 series tab, i.e. formed with a hole 17 for connection purposes. As seen in Figure 3, the tab 14 is symmetrical, being formed at its left hand end (received within the body of the moulding 1) with a duplicate opening 16' and a hole 17'. Although when assembled, these play no part in the function of the tab, the fact that the tab is symmetrical end for end means that either end can be fitted into the moulding 1 and the supply of tabs can therefore be bowl-fed for purposes of automatic assembly, since there is no need to discriminate between the two ends. Insertion of the tab both makes frictional contact with the lead 4 and further assists in anchoring the diode 3 in position within the moulding 1.
  • the tab 14 when assembled, the tab 14 constitutes a male terminal for connection to the supply circuit and the recess 6, in conjunction with the lead 5, forms a female terminal socket for the reception of a male terminal 18 (shown in dotted lines in Figures 1 and 3) of a lamp or other illuminated component, the body of which is shown in dotted lines at 19.
  • the terminal 18 forms a firm push fit in the recess 6 and thus both makes good frictional contact with the lead 5 and also holds the adapter unit as a whole firmly in position.
  • FIG. 4 One particular application of the adapter is shown in Figure 4 where the adapter 1 is illustrated as fitted to an illuminated push button switch.
  • the push button switch itself is a standard item comprising a push button 21 with a translucent body portion 22 illuminated by an internal lamp (not seen).
  • a male terminal connected in the lamp circuit is shown partly at 23, the remainder of the terminal being received in the connection socket of the adapter 1.
  • the adapter 1 is firmly pushed onto the terminal 23 and this serves both as a mounting for the diode within the adapter and, at the same time, makes a positive electrical connection to one lead of the diode.
  • the other lead of the diode is connected to the male terminal 14 of the adapter to which an external connection can be made in the usual way, thus including the diode in series circuit with the internal lamp.
  • Figure 3 shows the diode 3 symbolically, that is to say as the normal symbol indicating a diode and showing that the current flow is from right to left, i.e. from the lead 4 to the lead 5. If the diode were inserted in the opposite sense, which is very simply done, i.e.by leaving the lead 5 straight and bending the lead 4 to a U-shape, the polarity is reversed and adapter units of either polarity can thus be produced very simply according to the requirement of the particular lamp with which it is to be used.
  • the adapter Since the adapter is an add-on feature it must be a low cost item, this being achieved by the use of frictional pressure contacts to the two leads in place of the usual soldering or welding processes which are labour intensive and therefore expensive.
  • the shaping of the moulding 1 also locates the terminal blade 14 in position by a similar frictional contact and thus considerably simplifies assembly.
  • an adapter in accordance with the invention is a self-contained unit which may be used in any circumstances where it is required to connect a diode in a series circuit with a small lamp holder or other illuminated component.
