Definitions

  • the present invention relates to electrical switchboards and, more particularly, to a combination of two electrical devices and of means for electrical connection between them.
  • the switch used also comprises devices for protection against any over-currents or over-voltages, these devices being disposed in the same box-shaped body of rigid plastics material which contains the switch and which performs the dual function of a mechanical support for its fixed and movable portions and of an insulator between the live metal parts.
  • a differential device is connected in series between the switch and the electrical system. This device can detect even very low leakage currents and can supply a corresponding signal to the associated switch to open its contacts by means of a suitable tripping device.
  • Switches and differential devices are formed in a manner such that their input connections, that is, those which are to be connected to the electrical supply mains, are accessible from one side of the respective box-shaped body, and their output connections, that is, those for connection to the electrical system to be supplied, are accessible from the opposite side.
  • connection between the two devices is very simple and requires only short connectors for connecting the output connections of the switch to the input connections of the differential device. If, however, the differential device has to be mounted beside the switch, the connection requires longer and more bulky connectors.
  • flexible insulated conductors each of which has one end fixed to one of the input connections of the differential device and which extend through a space in the bottom of the box-shaped body of the differential device emerging from the same side as the output connections of the differential device, the opposite end of each conductor being fixed to one of the output connections of the switch, as shown in Figure 1.
  • the electrical connection means comprise a plurality of substantially rigid metal strips insulated from one another electrically and extending, for part of their length, through a passageway defined by the two adjacent sides of the two devices.
  • a four-pole electrical power switch and a differential device are indicated 10 and 11, respectively, and are mounted side by side on a common support panel 12 of an electrical switchboard by suitable fixing means, not shown.
  • the switch 10 is mounted on a spacer base 8 of a thickness such that the front of the switch is aligned with the front of the differential device 11.
  • the mechanical connection between the two devices is strengthened by U-shaped clips, indicated 9, which can be snap-engaged in suitable seats provided in their box-shaped bodies.
  • the switch 10 has four input connections accessible through corresponding holes 13 in the top of its box-shaped body.
  • the connections are constituted, for example, by plates with threaded holes and respective fixing screws, not shown, which can be operated through corresponding holes 14 provided in the front of the switch body.
  • Four output connections, just the same as the input connections, are accessible through corresponding holes provided in the bottom of the switch body.
  • Similar output connections are provided on the bottom of the differential device 11.
  • the latter also has four input connections but these are not accessible from outside the device. However, one of them, indicated 15, is made visible in the drawing by the removal of a portion of the top of the differential body.
  • the ends of four flexible electrical wires 16 with insulating sheaths are fixed to these four input connections during the assembly of the device, the wires extending through a space 17 along the rear of the differential body 11 and emerging from the bottom of the device through suitable holes in the bottom of the body.
  • the opposite ends of the wires 16 can be inserted and clamped in the output connections of the switch 10. In the drawing, only two wires are shown connected.
  • each strip 21 is formed by an intermediate portion which extends through the passageway 20 and is bent at 90° at two points, and by two small plates with holes welded to the two ends of the intermediate portion.
  • An insulating sheath preferably formed by immersion in a thermosetting epoxy resin and subsequent drying, covers the strips, insulating them from one another electrically, naturally except for the ends with the holes.
  • the passageway 20 houses, above the strips 21, a known device 24, associated with the switch 10, for detecting and indicating the state of the switch.
  • the device 24 comprises an arm 24a which interferes with a linkage of the switch through a suitable side opening in the switch body, and a micro-switch 24b operated by the am 24a.
  • the passageway 20 is closed by a covering panel which is connected to the fronts of the two devices disposed side by side.
