Definitions

  • the present invention relates to an electrical control and connection system intended for use primarily for electric lighting but which may be used for power outlets.
  • E o 299 811 in the name of Telemechanique, proposes a trunking system having the normal electrical Line and Neutral conductors, together with safety earthing connection, supplemented by a further conductor which is used to provide control for the connected lighting fixtures.
  • This further conductor is divided at some of the tap-off points thus providing a point at which an additional switch or other control device can be inserted in the system.
  • a known disadvantage of this approach is that a plug must be inserted into every such tap-off point merely to maintain continuity of the further conductor.
  • British Patent Application 2 255 865 A in the name of MK Electric proposes an earlier MK system again with an array of four conductors one of which provides a control line.
  • the control line is terminated at every tap-off point or outlet, the adjacent terminated ends of the conductor being electrically connected by a normally-closed switching mechanism.
  • two differing forms of plug are used to engage with the tap-off facilities in the array; one of these plugs is intended to operate the switching means incorporated in the tap-off facilities whilst the other form of the plug leaves the switching mechanism unaffected and thus the two adjacent ends of the busbar or conductor remain electrically connected.
  • a second object of an embodiment of the present invention is to provide the degree of flexibility required in a lightining installation without increasing the number of connectors on the plug or tap-off facility beyond the number of conductors in the system.
  • German Patent application DE 3 346381 A, Brown, Boveri & Cie uses a single design of connector and the flexibility of the system is correspondingly reduced.
  • the system is particularly concerned with the mechanical design of the components and, particularly, in the adoption of a modular design for the modules. No switching is included in the arrangement.
  • a similar approach to the design of the modules is taken in an early German Patent DE 2 415 727, Brandi, although this system is not specifically intended for lighting applications. More particularly this system can be distinguished from the above and from the present application in as much as Brandi does not seek to produce a system capable of supporting branches in the controlled circuits nor to provide control of lighting fixtures from more than one place nor are there any switching in the control lines. Only the Line conductor is switched. It is a further object of an embodiment of the present invention to provide the required degree of control whilst permitting both linear and branched circuit configurations.
  • An electrical lighting and connection system comprises an electrical lighting control and connection system comprising a longitudinal array of at least five electrical conductors including Line, Neutral and Earth conductors and at least two additional conductors provided for control purposes, characterised in that at least a first of said additional conductors is permanently provided with one or more switch means along its length and included in said array, said array having at least two lighting power outlets along its length, the conductors running between said outlets, a said switch means operable to make or break electrical continuity in said first additional conductor between adjacent said outlet, said outlets each providing access for a connector to connect to said conductors.
  • the system of the present invention may comprise a first style of connector adapted to fit into a said outlet and to connect with at least two of said conductors, said first style of connector being so adapted and arranged to operate said switch means on insertion into said outlet and/or a second style of connector adapted to fit into a said outlet and to connect with at least two of said conductors, said second style of connector being unable to operate said switch means on insertion into said outlet.
  • a third style of connector may have a positionable means to operate or not operate said switch means as required. Where connectors are not required but sections of the array require to be isolated a "dummy connector" or rather operating means adapted to fit into the array to operate the switch means may be inserted into the array preferably but not necessarily at an outlet.
  • the array of the system may be encased in ducting or the array may be in the form of a multi cored cable or ducted sections of the array may be joined by a multi cored cable of the array which may have outlets along the length of the cable.
  • the connectors may have electrical switches to control sections of the array. These switches may themselves be manually or remotely controlled.
  • Figure 1 shows diagrammatically a part of a longitudinal array of conductors with two different styles of connector according to the invention
  • FIG. 1 shows the arrangement of Figure 1 with different connections
  • Figure 3 shows the arrangement of Figure 1 with different connectors
  • Figure 4 is a diagram of a flexible wired system according to the invention in which flexible conductors are connected to ducted conductors.
  • Figure 5 shows a connector at an outlet of the arrang ents shown in Fig.s 1-4;
  • Figure 6 shows a length of trunking for the arrangment shown diagrammatically in Fig.s 1 to 4 sectioned to show the control conductor fitted with a switch means, the other conductors are not shown;
  • Figure 7 shows the same length of trunking shown in Fig. 6, but with the switch operated by the insertion of a switch operating means
  • Figure 8 shows a first style of connector including switch operating means combined together as one assembly inserted into a combined outlet and switch means for the system shown diagrammatically in Fig.s 1 to 4;
  • Figure 9 shows a second style of connector according to an embodiment of the invention similar to that shown in Fig. 8 but without a switch operating means;
  • Figure 10 shows a third style of connector according to an embodiment of the invention which may be set to operate a switch or not as required for the system shown in Fig.s 1 to 4.
  • Figure 1 shows a length of a busbar conductor array system with three continuous conductors L, N and E for Line, Neutral and Earth respectively. Two additional conductors, designated SL and 2W are also shown which serve to carry supply and control signals to connected devices. Power outlets SI, S2 and S3 are shown at A, B and C respectively and several normally-closed switches 7, 7' and 7" are incorporated in the busbar designated SL at each outlet. Each switch 7 is shown as being next to each outlet but may be within or spaced from each outlet designed to be operated to the open position when one of at least two differing styles of connector is inserted in to the socket whilst the insertion of another style of connector leaves the switch in the closed position.
  • Switches 7 may also be opened by an operating means hereafter referred to as a "flag" as will be described with reference to Fig. 7.
  • Flags provide no connections but merely operate switches 7 when inserted. They also indicate to the user where conductor SL is broken. The switch 7 reverts to the closed position whenever a corresponding connector or flag is removed.
  • the figure shows a connector A of the first type inserted into the leftmost socket si on the figure, the connector A having contacts numbered 1 to 5 and terminals 23 to 27 inclusive, and has an operationg member (not shown) causing the associated switch 7 to open separating the contacts 6 and 18 in the busbar designated SL.
  • a switch 22 forming part of the wiring installation, is connected to the connector A by means of a flexible cable. The switch may be operated to supply electric current from the Line busbar, designated L, via contact 3 and terminal 25, switch 22 and terminal 24, to contact 4 on the SL busbar thus energising the busbar to the right of contact 18.
  • a lamp 38 is shown connected to the same connector A having switch 22 and which will be illuminated when the switch 22 is ON.
  • a further connector C of the second style described above, is shown inserted into the rightmost socket 53, and which has terminals numbered 33 to 37 inclusive. No switch operating means is inserted hence the contact 6" and 18" of switch 7" are in the closed position.
  • a lamp 39 is shown connected to terminals 34 and 36 of the connector C by means of a flexible cable and is thus, when the connector is inserted in to the socket, electrically connected to the SL and Neutral busbars. The lamp will therefore illuminate whenever the SL busbar is energised by the operation of switch 22.
  • Figure 2 therefore shows an alternative arrangement in which a switch 22 has been connected to a second type of connector C at socket S3.
  • the connection between 6" and 18" of switch 7" is unbroken. Control is therefore exerted by the switch in both directions along the busbar designated SL.
  • the user might not, at the time of purchasing the connector, know whether he wishes to use it in accordance with Figure 1 or Figure 2. It is therefore desirable that the user may easily change the configuration of the connector from that of the first type of connector to that of the second type and vice versa. This may be achieved by using a third type of connector as is shown in Figure 10 and which will be described below.
  • Figure 3 shows a similar section of the busbar system to that shown in figure 1 and demonstrates how the system may be used to provide control from more than one point on the system.
  • the lamp 39 originally shown on the right of Figure 1 is now shown in the centre at socket 52 as discussed in preceding paragraphs.
  • a control switch E having contact arm 72 and contact 70 is connected by a flexible cable to the connector C, having contacts numbered 33 to 37 inclusive, and when operated serves to connect contacts 33 and 35.
  • the switch thus energises the busbar designated 2W when the switch is in the closed position.
  • FIG. 3 at socket SI an alternative device is shown connected to connector A.
  • This has the operating coil of a contactor or relay connected to contacts 23 and 26 of the connector, that is, electrically connected between the 2W busbar and Neutral busbar.
  • the relay or contactor may be made to operate by switch E.
  • the contacts of a relay or contactor F are marked 52 and 54 and are of conventional change-over pattern.
  • These contacts 52 and 54 are shown connected in conventional two-way switching mode with a further two-way switch, D, which may be connected by a flexible cable to terminals 53 and contact 54.
  • the common terminal 60 of the switch D having contacts 61 and 62 is supplied from the Line busbar via contact 62, or alternatively via contact 54 and terminal 53.
  • relay contacts F or the switch D will either energise or de-energise the busbar designated SL thus turning the connected lamp 38, on or off. Since relay or contactor F may be controlled by making contacts 70 and 72 of switch E, a full two-way switching circuit has been established.
  • the connector shown used to connect the switch E to socket S3 in Figure 3 is of the first style intended to operate the switch 7" to an open position. It will be appreciated that a second or third style of connector may also be used which would leave 6" and 18" electrically connected. In this case further lamps may be connected to any extension of the system from the right-hand side of Figure 3.
  • Figure 4 shows an isolated section of the busbar system and it will be appreciated that, since the number of conductors or busbars is the same as the number of contacts in the connector, the same connector as is used to connect devices to the busbar system may be used to interlink sections of the busbars system together. It will be further appreciated that this isolated section of the system could be represented by a length 180 of multi-core electric cable having a multi-pin plug G attached at one end whilst the other end of the cable is connected to a multi-pin sockets or plug H. Between G and H a socket 35 incorporating or associated with a switch 7" as described above. Further is will be appreciated that to increase the number of lighting fixtures or switching systems connectable to such an isolated portion of the system, the number of sockets may be further increased. This also enables a flexible approach to connecting parallel isolated lighting fixtures including other busbars.
  • Figure 5 shows the arrangement of a connector 80 which may be associated with or not associated with a switch operating means or as a plug G at one end of a ducted array.
  • the connector 80 is inserted in an outlet 81 in ducting or in a flexible multi core cable.
  • the connector has a flexible cable 82 which may be used to connect a control switch or light neither of which are shown.
  • the connector 80 is shown with its cover removed for clarity, and consists of a body 83 fitted with four shorter pins 84 to 87 inclusive, for making contact with line conductor 88, neutral conductor 89, and the two control conductors 90 and 91, and a longer earth pin 92 for making contact with the earth conductor 93.
  • the body 83 incorporates two prongs 94 which may be flexed by applying pressure at pads 95.
  • the prongs 94 engage with the aperture of the outlet at 96 to retain the connector 80 in the outlet 81.
  • Cable 97 securely attaches the outer sheath of the flexible cable to the connector body 83 by means of clamping screws 98. This ensures that any strain on the cable in the direction of arrow R is transmitted from the cable 82 to the connector body 83 and through the prongs 94 to the aperture 96 of the outlet 81.
  • the outlet 81 is fitted to a rigid length of busbar trunking (not shown) the strain on the cable in the direction of arrow R is then resisted by the fixings of the trunking to the building structure.
  • the connector is fitted to a length of flexible cable as shown by C in Figure 4 then provision is made for the connector to be fixed to a suitably strong structural member (not shown) .
  • FIG. 6 shows a sectioned length of trunking 101 which comprises a rigid duct body 99 which encases the array of five conductors 88 to 91, of which only the control conductor 90 fitted with a switch means 102 is shown, the switch means 102 comprises two fixed contacts 104 fixed to the twisted ends 105 of the conductor 90, and a moving contact plate 106 with contact points 107 at each end of the plate.
  • the moving contact plate 106 is biased against the fixed contacts 104 by the compression spring 108, hence providing electrical continuity of the conductor 90.
  • An aperture 109 is provided in the wall of the duct body 99 to permit operation of the switch means 102.
  • FIG 7 shows the same sectioned length of trunking 101 as shown in Figure 8, however in this case a switch operating means 110 acting as a flag has been inserted into the aperture 109 to operate the switch means 102.
  • Switch operating means 110 comprises a body 111 formed of plastics which has a protrusion 112 and two flexible latching members 113 which are similar to the flexible latching members 984 shown in Figure 5.
  • the flexible latching members 113 may be flexed inwards by finger pressure on surfaces 114 to allow insertion and removal of the switch operating means into and out of the aperture 109. Insertion of the switch operating means 110 into the aperture 109 causes the protrusion 112 to push the moving contact plate 106 against the force of the compression spring 108 causing the contacts 104 and 107 to open breaking the electrical continuity of the conductor 90.
  • Figure 8 shows a connector of the first style 120 which comprises a plug part 121 and switch operating means part 122 inserted into a combined outlet 81 and adjacent switch means 102.
  • the plug part 121 and outlet 123 are similar to that shown in Figure 5 and the switch operating means part 122 and the switch means 102 are smiliar to that shown on Figures 6 and 7, apart from the two flexible latchings members 125 only one of which is visible each of which comprises a surface 126 and two patching portions 127 and 128 which retain the connector 120 in the apertures 129 and 130 respectively. For clarity only one conductor 90 has been shown.
  • Figure 9 shows a connector of the second style 140 similar to the first connector style 120 shown in Figure 8 but without a switch operating means. Hence when the second style is inserted into a combined outlet 81 and adjacent switch means 102 the plug 141 makes electrical contact with the conductors as shown in Figure 5, but the switch 102 is not broken. Hence the plug is electrically connected to both portions of the conductor 902 and 903 of conductor 90.
  • Figure 10 shows a connector of the third style 150 which is similar to that shown in Figures 8 and 9, except that the switch operating means part 152 may be positioned to either one of the modes shown in Figures 8 and 9.
  • the body 156 of the third connector style is sectioned to show the detail of the switch operating means part 152.
  • the switch operating means part 152 comprises a moveable pin 153, a flat leaf spring 154 which is fixed by screw 155 to the body 156, and a locating pin 157 which is fixed to the leaf spring 154 and free to move in hole 158.
  • the moveable pin 153 has two detents 159 and 160 which engage with locating pin 157.
  • Figure 10 shows the moveable pin 153 in a first position such that the protrusion 161 has operated switch 102 to break the electrical continuity of the conductor 90.
  • Moveable pin 153 is then free to move in the direction of arrow P to a second position where locating pin 157 will engage with indent 160.
  • the protrusion 161 is retracted such that it does not touch the moving contact plate 106 when the third part is inserted nto the outlet 81 and switch 102.
  • the switch is unbroken and the plug part 151 makes electrical contact with both portions 902 and 903 of conductor 90.
