Definitions

  • This invention relates to a leaktight electrical plug for electrical ducting, in particular but not necessarily of the suspended type, with conducting bars located in leaktight slots arranged within the ducting on the sides thereof.
  • Suspended electrical ducting in which a straight metal enclosure which is open at the bottom houses insulating supports arranged along its sides in which a plurality of straight open slots each containing a conducting bar are formed are known, for example from EP0015365 .
  • the slots formed in the two supports face each other at a convenient distance and form a space into which an electrical connecting plug can be inserted at any desired point along the length of the ducting.
  • the cited document in particular describes a connecting electrical plug which when inserted into the ducting brings contact blades into contact with the conducting bars through rotation or bending of the former.
  • connecting plugs are provided with contact clamps which must exert a suitable pressure on the sides of the conducting bars, as is required in the situation where significant currents of the order of tens of amperes, typically from 10 to 20 A, have to be transferred.
  • Friction between the contact clamps and the conducting bars means that considerable force has to be applied.
  • the ducting in Figure 1 comprises a metal enclosure 1, which is open at the bottom, within which there is housed a pair of elements 2, 3, of insulating material supporting and guiding electrical conductors.
  • the conductors preferably but not necessarily six in number for each element 2, 3, comprise four conducting bars 4, 5, 6, 7 for the R, S, T phases and the neutral N of a three phase system and two conductors 8, 9 for an auxiliary voltage.
  • the conductors are housed in rectilinear slots formed within the supporting elements and collectively identified by reference number 10.
  • the slots are hermetically sealed by a plastic sheet 11, which is insulating and perforatable, welded by heat/compression or extruded over the entire surface of the support onto which the slots open.
  • enclosure 1 located between supporting members 2, 3 facing each other, there is formed a channel 12 for housing electrical plugs and other auxiliary elements.
  • Indicatively channel 12 has a depth of the order of 50 mm and a width of the order of 53 mm.
  • At the mouth of the channel enclosure 1 has two projections 13, 14 facing each other which act as hooking members for a lower cover panel, not illustrated, and for electrical devices, such as connecting plugs, housed within the channel.
  • top enclosure 1 At the top enclosure 1 is shaped to form an internal recess 15 and alongside the latter two external recesses 161, 171 having a trapezoidal cross-section into which convenient suspending stirrups may be inserted.
  • the plug essentially comprises a supporting box structure 16 in which a plug body 17 is housed, hinged to structure 16.
  • the plug body 17 can adopt a retracted or electrically disconnected position relative to the supporting structure is housed, hinged to structure 16, as illustrated in Figure 2 , and an electrically connected position, as illustrated in Figure 3 .
  • Plug body 17 is provided on one side with a plurality of electrical contacts projecting from the side, at least two, 19, 20, or more, up to a maximum of six in the preferred embodiment, depending upon the user's requirements.
  • the electrical contacts are contained in a side portion 21, hereinafter referred to as the window, surrounded by a frame 22 of resilient material which makes a leaktight connection with plastic sheet 11 ( Figure 1 ).
  • Box structure 16 essentially has a transverse cross-section of dimensions corresponding to those of channel 12 with an upper rib 23, and when the plug body is in the retracted position ( Figure 2 ) it is freely and wholly inserted into channel 12 with rib 23 finding a precise housing in recess 15 in the enclosure, without electrical contacts 19, 20 interfering with the supporting and guide elements for the conducting bars.
  • Box structure 16 is anchored to enclosure 1 of the ducting by suitable teeth 24, 25 supported by resilient tongues formed by the lower part of a side of the box structure and although not visible in Figures 2 and 3 by similar teeth formed on the opposite side.
  • plug body 17 can be rotated relative to supporting structure 16 and caused to adopt the position illustrated in Figure 3 in which resilient frame 22 bears against insulating sheet 11 ( Figure 1 ) and contact members 19, 20 come into contact with the conducting bars and establish electrical connection after perforating insulating sheet 11.
  • Rotation of plug body 17 relative to the supporting box structure is brought about by an ordinary device such as a screwdriver which is removably inserted into a suitable seat formed in the support and engaged with an eye or fork formed on the plug body.
  • an ordinary device such as a screwdriver which is removably inserted into a suitable seat formed in the support and engaged with an eye or fork formed on the plug body.
  • the device acts as a second order lever (fulcrum-resistance-power) amplifying force.
  • Figure 4 shows the different components which form a leaktight plug according to this invention in a preferred embodiment.
  • Box structure 16 of a plastics material such as polyamide, polypropylene or the like, containing suitable additives, for example glass fibres, comprises a rectangular platform 26 above which there is at one extremity a wedge-shaped case 27, with a base and an apex, which is internally hollow and open at the base.
  • bracket 28 which connects to the apex of case 27 through rib 23.
  • bracket 28 Projecting portion 29 of bracket 28 is provided with a circular opening 30, in vertical alignment with a corresponding circular opening 31 formed in platform 26.
  • Relatively resilient toothed vertical tongues 32, 33, 34 providing a snap connection with projections 13, 14 of the enclosure are formed on both the long sides of the platform.
  • Plug body 17 comprises a box 35 and a cover 36, coupled together through an intermediate resilient seal 37, preferably but not necessarily co-moulded with one of the two components, for example, as illustrated in the figure, box 35 (and also seal 22 surrounding window 21 ( Figure 2 ) is conveniently co-moulded with box 35).
  • box 35, cover 36 The two components (box 35, cover 36) are locked together through a pair of teeth 38, 39 located on one side of the cover 36 which engage in corresponding seats 40, 41 formed in box 35 and through a pair of screws 140, 141 passing through cover 36 which screw into corresponding seats 42, 43 formed in box 35.
  • a substantially cylindrical pin 44 On the upper surface of box 35, close to the edge thereof, there is formed a substantially cylindrical pin 44, with suitable voids, onto which is fitted a contact member 45 in the form of a semi-cylindrical ring with bent extremities which are housed in the voids in pin 44.
  • pin 44 cover 36 is provided with a pressure member 46 which when housed in a void in pin 42 completes its cylindrical profile pressing one of the bent extremities of contact member 45 together with a metal tongue 47 of an earth contact unit 48 which will be described below.
  • Pin 44 together with pressure member 46, forms a journal which is inserted into opening 30 of the supporting member and when the supporting member is inserted into channel 12 is housed in recess 15 ( Figure 1 ) with contact member 45 in electrical contact with metal enclosure 1 of the ducting which acts as an earth conductor.
  • the earth connection is therefore made when the plug is inserted into the channel, before the other electrical connections are made, as the plug body passes from the retracted position to the electrically connected position.
  • journal 44 box 35 In axial alignment with journal 44 box 35 has a circular opening 49 on its lower surface for the passage of connecting electrical cables.
  • Opening 49 is surrounded by a collar 50 projecting towards the exterior of the box.
  • Collar 50 is inserted in the manner of a journal into opening 31 on platform 26 of supporting box structure 16.
  • bracket 28 Insertion is permitted by the relative elasticity of bracket 28 and its projecting portion 29.
  • Opening 49 is closed off by a conventional rubber cap 51, which can be perforated in such a way as to permit the passage of a sheathed electrical cable and at the same time ensure a leaktight seal.
  • a similar circular opening 52 is formed through the connection of box 55 to cover 36 on the side of body 17 closest to pin 44 and opening 49.
  • This opening which is also closed off by a conventional perforatable rubber cap 53 may be used as an alternative to opening 49 for the passage of a sheathed electrical cable, or, as will be seen below, for the electrical connection of an auxiliary fuse-holder box.
  • the sheathed cable is firmly anchored to the plug body by means of cable clamping saddle 84 with tightening screws 85, 86 which screw into corresponding seats (18, 87 or 18, 88) formed in box 35.
  • the saddle can adopt two positions, rotating on common seat 18, depending upon whether the sheathed connecting cable to the plug is caused to pass through opening 52 or opening 49.
  • the face of box 35 opposite that in which opening 52 is formed is provided externally with an annular sleeve 54 with an elongated eye opening 55.
  • Sleeve 54 may be replaced by a fork with two teeth between which there is a space equivalent to opening 55.
  • sleeve 54 is housed in the bottom part of case 27 provided for the purpose with an elongated opening on its inner and outer sides which allows the sleeve to move out for passage of the plug body from the retracted position ( Figure 2 ) to the electrically connected position ( Figure 3 ) and vice versa.
  • the openings also act as a guide to prevent vertical displacement of the sleeve (and the plug) as it moves outwards.
  • Figures 5, 6 show in cross-section along the line A-A in Figure 4 , case 27, sleeve 54 and the manner in which plug body 17 is rotated from the retracted position to the electrically connected position relative to supporting structure 16 through the help of removable external means.
  • the electrical plug is inserted into channel 12 of enclosure 1 with rib 23 housed in inner recess 15 of the enclosure and the edges of platform 26 adjacent to projections 13, 14 of the enclosure.
  • the plug body adopts the electrically connected position in this way, without stress.
  • cover 58 has a fork 59 which makes a snap connection on a pin 60 formed in the base of case 27 and integral therewith in such a way that the cover is hinged to the box structure and can adopt an open position illustrated in Figures 5, 6 and a closed position in which a tooth 61 at the opposite extremity of cover 58 makes a snap connection with a projection 62 formed on the inside surface of resilient tongue 33 supporting a locking tooth of the box structure which is forced into the engaged position.
  • cover 58 in the closed position may be provided by teeth located on the side of the cover which engage the sides of case 27.
  • extremity 61 of the cover may force resilient tongue 33 into the engaged position without the latter being necessarily provided with projection 62.
  • Cover 58 also has a rib 63 with a wedge-shaped projection 64 on its inner surface which when the cover is in the closed position interferes with the side of sleeve 54, or more specifically with a fin 65 on one side thereof, immobilising the plug body in the electrically connected position and forcing it in a leaktight manner against one or other of members 2, 3 supporting and guiding the conducting bars, depending upon the orientation in which the plug is inserted into the ducting.
  • wedge-shaped projection 64 interfering with a fin 68 formed on the side of sleeve 54 opposite that where fin 65 is located, immobilises the plug body in the retracted position and ensures that the plug can be inserted into the ducting without any interference between contact members 19, 20 and one or other of the members supporting and guiding the conducting bars.
  • this function of immobilising the plug body in one or other of the two positions may be brought about through a projection, which cannot be seen in the figures, formed externally on the underside of the plug body and housed in a groove 145 formed in platform 26 ( Figure 4 ).
  • the position in which the plug body is located can be checked, even when the plug is inserted in channel 12, through a window 147 made in platform 26 which displays one or other of two words, for example ON-OFF, located on the underside of the plug body, to the user depending upon the position of the plug body.
  • cover 58 may be provided at the extremity at which tooth 61 is located with an eye 66 which when the cover is in the closed position fits between the corresponding pair of eyes 67 formed in a projection on the underside of platform 26.
  • Eye 66 and pair of eyes 67 comprise a lead seal safety device, that is a seal provided by a wire inserted into the eyes and irreversibly lead sealed, opening of the cover then only being possible by breaking the seal.
  • eyes 67 may be made in such a way as not to project from the underside of platform 26.
  • plug body 17 The description of the internal components of plug body 17 may now be completed with reference to Figure 4 .
  • box 35 there are formed a plurality of rectangular prismatic housings, one for each contact member.
  • housing 69 for earth contact unit 48 there is a housing 69 for earth contact unit 48 and six housings, identified by numerical references 70, 71, 72, 73, 74, 75 respectively, to each receive a containment box for a member in contact with one of the different conducting bars present in one of supporting and guide members 2, 3.
  • each box contains a terminal electrically connected to the contact element for securing an end of an electrical cable.
  • the terminal is for example of the known "locking spring” type, with release key or lever to permit insertion of the cable end.
  • housings 70-75 have a pair of opposing projecting teeth in each housing, which cannot be seen in the figure, which form a snap connection with a corresponding pair of recesses formed on the side surfaces of the various boxes, holding them in position.
  • Figure 4 in fact shows two boxes 77, 76, for insertion into one of the three housings 70, 71, 72 (specifically housing 72) and housing 73 respectively.
