Definitions

  • This invention relates to an electrical power outlet incorporating a safety switch with a removable actuator.
  • the present invention provides an electrical power outlet comprising a connector part adapted to receive a complementary connector part, electrical switch contacts for interrupting the supply of electrical power to said connector part , and a removable actuator wherein removal of said actuator opens said switch contacts .
  • a power outlet e.g. a socket, incorporating an electrical isolating switch which is actuated by a removable component .
  • the power outlet may be fixed, e.g. by being mounted to a wall or portable, e.g. by being provided with a flexible electrical cable to connect it to a fixed electrical supply such as a wall socket or the like.
  • a fixed outlet removal of the actuator enables a parent or responsible person to prevent unauthorised use or unsafe interference with the power outlet in their absence - for instance when a child is left unsupervised.
  • the operator can conveniently have such control wherever he or she is working without having to return to the fixed supply point - e.g. wall socket.
  • an electrical power outlet comprising an integral cable for connecting the outlet to an electrical supply and a removable actuator for selectively interrupting the electrical supply to the outlet .
  • the removable actuator is preferably provided with a means for attaching it to an operator so that the removable actuator can be automatically detached from the socket outlet if the operator leaves the appliance unattended. This is particularly beneficial in the case of a portable socket outlet . As well as making the tool or appliance safe and inoperable by unauthorised persons, the removable actuator remains with the operator ensuring that the power cannot be reinstated without the operators co-operation. This preferred feature also provides extra safety in the event that the tool or appliance is dropped in which case the removable actuator will be pulled from the socket outlet disconnecting power to the tool or appliance. It will be appreciated that using an electrical power outlet in this way is both novel and inventive and thus when viewed from a further aspect the present invention provides a method of using electrical power outlet operated by a removable actuator comprising attaching the removable actuator to an operator during use .
  • the removable actuator may be arranged to interrupt just one pole of the electrical supply, but preferably both poles are interrupted.
  • retention means are provided to prevent removal of the actuator unless a certain minimum force is applied. This prevents the actuator being removed by accident during use and thereby causing a nuisance interruption of electrical power, but allows the power to be interrupted as a result of a tool or appliance being dropped or if the actuator is sharply tugged e.g. in an emergency.
  • a release means is provided to overcome said retention means and allow the actuator to be removed under normal circumstances .
  • FIG 1. shows particular features of an embodiment in the form of a fixed socket outlet
  • FIG 2. shows the relationship of the power supply, extension lead, portable socket outlet, removable actuator, operator and tool of a second embodiment when in use;
  • FIG 3. shows the relationship of the same aforementioned items when the operator is absent; and
  • FIG 4. is a close-up view of the second embodiment showing particular features thereof . the portable socket outlet application.
  • this embodiment comprises a fixed socket outlet with a removable actuator which operates switch contacts. Electrical connections to the socket contacts 1 are made via the switch contacts 2. When the removable actuator component 3 is inserted into the socket outlet 4 the switch contacts are closed connecting the electrical supply to the socket contacts 1. Correspondingly when the actuator is removed, the switch contacts will be opened again thereby interrupting the supply of electrical power to the socket contacts 1.
  • FIG 2. and FIG 3. there is shown a second, portable, embodiment of the invention.
  • This embodiment comprises a portable socket outlet 5 provided with a removable actuator 3 which is secured to the operator 6 by means of an attachment loop 7.
  • the socket 5 is connected to a mains cord 8 provided with a plug 9 for connection to the mains supply 10 via a conventional wall socket.
  • the removable actuator 3 In order to operate the tool 11 the removable actuator 3 must be engaged in the socket outlet 5. If the operator 6 leaves the tool 11 unattended, because the removable actuator 3 is attached to him it is automatically removed from the socket 5 opening electrical contacts inside, thus disconnecting electrical power to the tool 11. The power cannot be reconnected until the operator returns and re-inserts the removable actuator 3 back into the socket 5.
  • the socket housing 5 is provided with a mechanical latching device comprising a movable internal lug (not shown) to locate with an appropriate feature 13 on the removable actuator 3. This prevents the inconvenience of the removable actuator 3 being inadvertently detached from the socket housing 5 in normal use .
  • the latching system can however be overridden in an emergency by directly pulling on the removable actuator 3 or the means of attachment 7.
  • the latch may be released by pressing on a button 12 which causes the lug to be withdrawn from the notch 13 , thereby allowing the actuator to be removed under normal circumstances .

Abstract

L'invention concerne une prise d'alimentation fixe (4) ou portative (5) comprenant un commutateur d'isolement de sécurité (2) fonctionnant avec un actionneur amovible (3) destiné à réaliser un isolement automatique avec l'alimentation principale lorsque l'opérateur laisse l'outil ou l'appareil électrique (11) branché dedans sans surveillance. On peut attacher l'actionneur amovible (3) à l'opérateur (7) de façon que l'actionneur amovible (3) soit automatiquement détaché de la prise (5) lorsque l'opérateur (6) s'éloigne de l'outil ou de l'appareil électrique (11).
