Definitions

  • the present invention relates to a mains electrical outlet and more particularly to such an outlet provided with manual switching facilities.
  • Mains electrical outlets are housed in standard size boxes and are usually either one-gang or two-gang. Attempts have been made in the past to provide switched electrical outlets with fault protection in the form of residual current devices but all previous attempts have either resulted in the need for nonstandard sized outlets or else the use of a two-gang box for a one-gang RCD protected outlet. There is thus a need for a switched electrical outlet which has RCD protection but which will fit in a standard size housing.
  • the present invention proposes to provide a switched mains electrical outlet which utilises the normal electrical contact assembly for making and breaking the power contacts together with a normal construction of manually operable switching means.
  • the linkage between these two elements is a controllable coupling operating in response to a fault detection mechanism.
  • the controllable coupling is in the form of an axial clutch which is capable of axial movement in the presence of a fault condition to thereby effectively disengage the mains contacts from the manually operable switch member to permit the mains contacts to open but when there is no fault condition the mains contact operating mechanism is locked to the operation of the manually operable switch member.
  • Figure 1 shows a diagrammatic representation of the overall assembly
  • Figure 2 shows a sketch of a manually operable member used witii the assembly shown in Fig. 1;
  • Figure 3 shows an exploded perspective view of a part of the assembly shown in Figure 1.
  • the preferred embodiment of the present invention is designed to result in a switched electrical outlet which has RCD protection built in but which occupies a standard outlet box.
  • the preferred embodiment utilises as far as possible normal operating mechanisms but replaces the normal fixed linkage between the manually operable switch on the outlet and the actual mains contact mechanism with a controllable coupling mechanism.
  • the normal mains contact operating mechanism is indicated by the reference numeral 10.
  • the mechanism consists of a contact carrier 12 carrying contacts 14 which in normal operation are biased by a biassing means 15 to a normally open condition with respect to fixed contacts 16.
  • the contact carrier is arranged to rotate in a plane normal to the plane of the paper in Figure 1.
  • a manually operable switch mechanism is generally indicated by reference numeral 18 and consists of a rocker switch 19 which is of the usual bistable type resulting from the use of an over-centre spring arrangement "where the rotational force required to overcome the spring to turn from on to off is greater than the rotational force exerted by the biasing spring 15, such that the switch system as a whole is also bi-stable for as long as the device is untripped.
  • a controllable coupling mechanism 20 in the form of an axial clutch.
  • the axial clutch is formed by a plate member 21 which faces a side wall 22 of the contact carrier 12.
  • the facing surfaces 21,22 are provided with one or more inter-engaging projections and recesses; the projections 22a being shown in more detail in Figure 3.
  • the plate 21 is arranged to be movable by the manually operable mechanism 18 in a rotational direction in and out of the paper as seen in Figure 1 but is capable of transverse or axial movement i.e to the left and right as shown in Figure 1 under the control of a fault detection system indicated generally by the reference numeral 22.
  • the arrangement is such that the fault detection mechanism 22, in the absence of a fault, causes the plate 21 to be held in engagement with the surface 22 on the contact carrier 12 so that movement of the manually operable mechanism 18 will also move the contact carrier 12 to open or close the power contacts. This is achieved by interposing a movable member
  • the member 23 between a surface 24 provided on an extension 25 to the plate 21 and a relatively fixed surface 26.
  • the member 23 interposed between the surface 24 and fixed member 26 prevents any axial movement of the plate 21.
  • the member 23 is withdrawn which allows relative movement between the members 24 and 26 which thus permits the plate 21 to move axiaily as a result of interaction between the projections and recesses on the contact carrier 12 and plate 21.
  • the projections of recesses have angled engaging surfaces which are designed so that the biassing means 15 exerts a sufficient rotational force on the contact carrier 12 to force the plate away from the surface 22 when the moveable member 23 is not interposed between the surface 24 and fixed surface 26.
  • a further advantage of the above arrangement is that in order to reset a socket which has been tripped by a fault condition, all that is required is that the switch rocker 19 be returned to the "off position and then placed into the "on" position again. If the fault has been cleared in the meantime then the switch will reset. However, if the fault is still present the operation of the rocker switch will have no effect on the contact carrier 12 due to the fact that the plate 21 will simply move axially as it also moves rotationally in response to operation of the rocker 19.
  • Figure 3 shows in an exploded perspective view a portion of the contact carrier 12 with the flag attached as well as the controlled coupling member. Rather than repeat the above description the same reference numerals have been used in Figure 3 as have been used in Figure 1.
  • the arms 31 engage the rocker switch 19 and cause the contact carrier to move with the rocker switch 19 in the absence of a fault.

Abstract

Une sortie secteur commutée comprend des contacts généraux de travail (14, 16), un système pour ouvrir et fermer les contacts, et un système de commutation manuel se présentant sous la forme d'un interrupteur à bascule (19). Un élément de liaison pouvant être commandé est disposé entre ce dernier et le système, de façon à ouvrir et à fermer les contacts, et un détecteur de panne (22) permet de commander le fonctionnement dudit élément. Dans la condition de liaison, le fonctionnement du système pour ouvrir et fermer les contacts (14, 16) est directement commandé par une manipulation de l'interrupteur à bascule (19), tandis que, dans l'autre condition, les contacts d'alimentation (14, 16) sont dans la condition de travail et l'interrupteur à bascule (19) n'est pas capable de les fermer.
