Definitions

  • ABSTRACT An adaptor, for an electrical power distributor track, is arranged so that it can be fitted into the open channel of the track in a first position, and can then be rotated to a second position in which spring-loaded contact means make contact with electrical power lines. Holding elements are provided on the adaptor which locate in recesses provided in the track to lock the adaptor into place.
  • the purpose of the invention is to provide an adaptor, of the general type mentioned above, which is of simple construction, inexpensive, and much smaller in size.
  • the improved adaptor of the present invention includes a selector contact which can be positioned for selectively making contact with different power lines, the selector contact being connected to a conducting member for conducting current to the consuming element.
  • the selector contact is arranged in a rotatable part of the adaptor so as to provide selectively for contact with an upper and/or lower power line on either side of the distributor track channel.
  • the adaptor of the present invention preferably includes means for securing the rotatable part of the adaptor in a desired position. Before the adaptor is fitted into the track, the rotatable part is arranged in a po sition corresponding to the power line to be used. The adaptor is then inserted into the channel, rotated into the contact position, and then screwed firm in a manner similar to that of the known single circuit adaptors.
  • the adaptor employs blade-like contact, which surrounds a conducting member.
  • the blade-like selector contact surrounds a rod with parallel flat sides.
  • the contact is spring loaded for pressure on the line.
  • the rotatable part is secured against rotation relative to the neighboring parts and, accordingly, when the adaptor is fitted and rotated into position, the rotatable part maintains the selected position.
  • the adaptor may be provided with a cap for securing the rotatable part. Such a cap could, for example, be screwed to the conducting member which carries the contact blade.
  • the adaptor may also include a clamping part, secured to the adaptor base and arranged for sliding movement, which can be screwed for clamping against the underside of the track in a known manner.
  • the adaptor is also provided with a contact lug which is spring-loaded outwardly, for making contact with a grounding line.
  • the ground contact need not be positionally adjustable since it remains unchanged in contact with the ground line even when different circuits are selected.
  • the adaptor may be provided with holding elements in the form of lugs, and the opposite sides of the adaptor can be provided with a different number of such lugs.

  • a ribbed ring 2 is screwed to a cylindrical metal body 1 and carries a clamp member 4 which is moved in a direction parallel to the center line 3 when the ring is screwed.
  • the body 1 has holding lugs 5, 6 and 7 arranged on opposite sides.
  • the adaptor is fitted by inserting it into the track of FIG. 10, first with lugs 5, 6 and 7 lengthwise in the channel of the track, and then rotating it through 90 so that the lugs fasten behind corresponding ribs in the track.
  • the clamp member 4 is then pressed against the underside of the track by screwing the ring 2, thus securing the adaptor in the desired position. Since opposite sides of the adaptor are not provided with the same number of lugs, it cannot be fitted the wrong way round.
  • a curved grounding lug 19 is screwed or riveted to the metal body 1. Since both the body 1 and the tube 21, which carries the consumer element, are fabricated of metal, a cable connectionfor the lug 19 is not necessary.
  • a plastic insert 8 is provided in the body 1, having channels for a fixed contact 9, and for a conducting member 10.
  • the conducting member 10 has an additional part 11 which is surrounded by the arms of a selector contact 12.
  • the selector contact 12 is carried in a rotatable part 13 made of plastic.
  • the selector contact is stepped and, by means of a spring 20, is urged against the opposing power line.
  • the upper part 11 of the conducting member 10 carries a cap 14 secured by a spring in the bore 16. Wires l7 and 18 are soldered respectively to the conducting member 10 and to the fixed contact 9.
  • the clamping part 4 has projec tions 22 which fit into the channel of the distributor track. Lugs 23, projecting towards the center, fit into recesses 24 in the metal body 1. On the underside of the clamping member 4, lugs are provided which fasten under the shoulder'26 of the ring 2.
  • the cap 14 is fixed to the conducting member which is situated between the prongs of the selector contact 12.
  • the conducting member 10' has a narrow zone 27 which is so dimensioned that the contact can be rotated through when placed at the height of the narrow zone.
  • the rotatable part 13 When in use, the rotatable part 13 is situated either with its underside on top of the insert 8 or with its topside against the cap 14. Apart from the position shown in FIG. 7, the contact blade can be set in any of the positions 12a, 1212 or 12c.
  • a protective cylinder 28 (See FIG. 7) is disposed above the contact blade 12 to eliminate the possibility of unwanted contact with the conducting part 10 with the rotatable part is in the lower position.
  • a cylindrical extension 29 serves the same purpose when the rotatable part is in its upper position.
  • FIGS. 9 and 11 to 21 The following discussion is directed to a second embodiment of the invention, shown in FIGS. 9 and 11 to 21:
  • the basic construction of this second embodiment is similar to that of the first embodiment.
  • the cap 14' is rigidly fixed to the conducting member 10'; it may be directly molded for example.
  • the rotatable part 13 also has a stepped contact blade 12, which is shown in detail in Flg. 20, fitted thereto.
  • the contact blade 12 is urged in the direction of the arrow A (see FIG. 9) towards the opposing power line.
  • the base points 32 and 33 of the bow-spring 30 are supported on a shoulder 34 of the plastic rotatable part 13'.
  • the bow 35 of the bowspring presses against the step, forcing the contact blade 12 radially in the direction of the arrow A.
  • the base zone 36 of the spring is in constant contact with the conductor member 10'.
  • the bow-spring therefore, because of its shape serves two purposes. Firstly, it provides the necessary contact pressure for the contact blade 12 in the direction of the arrow A, and secondly, serves to clamp the rotatable part 13 to the conductor member 10'.
  • the conducting member 10 has upper and lower notches 39 and 40, and a narrow zone 38 in the middle.
  • the notches 39 and 40 mark the upper and lower positions of the rotatable part 13, corresponding to the upper and lower power lines of the distributor track.
  • the narrow zone 38 permits free rotation of the part 13' in the mid-way position between the upper and lower notch positions.
  • a recess 41 is provided (e.g., see FIG. 14) into which a projection 42, formed on the insert 8', can be located. Rotation when in the upper position is prevented by the cap 14, the form of which corresponds to the recess in the top of the rotatable part 13'.
  • the cap (see FIG. 19) has a symmetrical form with flattened sides.
  • the recess 45 in the top of the rotatable part is correspondingly round with two parallel flats 44.
  • the outwardly bent lug of the grounding contact 19 (see FIG. 15) is riveted to the body 1 of the adaptor which is also of metal for example, pressure molded aluminum. This ground connection is intended to make contact with the ground line 43 of the track 31 (FIG.
  • the clamping part 4 is circular and not square.
  • the power track 31 has internally on both sides plastic inserts 31a and 31b, each having two power lines.
  • the power lines are flat copper wires embedded in the plastic inserts. Inwardly, the power lines are open so that the contact blades 9 (or 9') and 12 (or 12) can make contact therewith.
  • the power lines are labeled R, S, T and N in FIG. 10. Lines are R, S and T are selectable, and line N is the common line.
  • the contact blade 9 (or 9') is in constant contact with the power line N. In FIG. 9 the rotatable part is so arranged that the selector contact will make contact with power line R.
