Definitions

  • the present disclosure relates to an electric arcing protection arrangement and method.
  • Electric arcing between a plug and a socket can cause serious damage to appliances and the electrical conductivity of the sockets.
  • pins of plugs and metal contacts on the sockets can burn. As they become pitted and blackened, their electrical conductivity reduces, eventually even becoming highly resistive. This can, for example, cause the damaged pins and contacts to heat up, and will eventually fail or burn up. This leaves electrical appliances and outlets in an unsafe condition, even when the damage appears minimal.
  • an electric arcing protection arrangement comprising:
  • the arrangement comprises a plug, wherein the plug comprises:
  • the arrangement comprises a socket, wherein the socket comprises:
  • the senor comprises a heat sensor arranged to monitor the temperature in a region of the connection of the plug and the socket, the electric arcing protection arrangement being such that if the temperature detected by the heat sensor is above a threshold value, the mechanism causes the pins of the plug to be withdrawn from the socket.
  • the senor comprises a light sensor arranged to monitor the light level in a region of the connection of the plug and the socket, the electric arcing protection arrangement being arranged such that if the light level detected by the light sensor is above a threshold value, the mechanism causes the pins of the plug to be withdrawn from the socket.
  • the senor comprises a heat sensor and a light sensor, the sensor being arranged such that:
  • the mechanism comprises at least one biasing arrangement to cause the pins of the plug to be withdrawn from the socket upon detection of electric arcing between the plug and the socket by the sensor.
  • the biasing arrangement comprises one or more springs arranged to push or pull the pins of the plug out of the socket.
  • an electric arcing protection method comprising:
  • the detection of electric arcing between the plug and the socket by a sensor comprises monitoring the temperature in a region of the connection of the plug and the socket by a heat sensor; and the mechanism is actuated if the temperature detected by the heat sensor is above a threshold value.
  • the detection of electric arcing between the plug and the socket by a sensor comprises:
  • the detection of electric arcing between the plug and the socket by a sensor comprises:
  • causing the pins of the plug to be withdrawn from the socket comprises activating at least one biasing arrangement to cause the pins of the plug to be withdrawn from the socket upon detection of electric arcing between the plug and the socket.
  • the electric arcing protection method is carried out by components in a plug.
  • the electric arcing protection method is carried out by components in a socket.
  • an electric arcing protection arrangement has a sensor for monitoring the presence of electrical arcing between a plug and a socket. When electric arcing is detected by the sensor, a mechanism causes the pins of the plug to be withdrawn from the socket.
  • Unwanted electric arcing can occur between plug pins and metal contacts of a socket. Electric arcing can cause pins and contacts to burn, becoming pitted and less conductive over time. With further use, the socket or appliances can become faulty. Electrical arcing can cause damage to devices, inlets/outlets, and even cause electrical shocks and fires. There is required an apparatus and method for protecting plugs and sockets from damage due to electric arcing.
  • Figure 1 shows a plug 102 connected to a socket 104.
  • Pins 106 of the plug 102 are in contact with electrical contacts (not shown) within the socket holes 107.
  • the plug 102 may, for example, be connected to a white goods machine, such as a refrigerator or a washing machine. Other examples of devices the plug 102 may be associated with include a television set or other electronic devices, a heater or a fan.
  • the plug 102 and socket 104 shown in this figure are a British 3-pin plug 102 and socket 104.
  • the plug 102 may have a different number of pins 106 and the socket 104 may have a corresponding different number of holes 107 for the pins 106 to enter.
  • the plug 102 and socket 104 may follow the European or the American 2-pin standards.
  • the plug 102 may be directly associated with an electronic or device or apparatus or be an adapter or a plug for an extension lead (which may lead to one or more sockets for other plugs).
  • the plug 102 is shown as having a sensor 108.
  • the sensor 108 is arranged to detect a change in the region of the plug 102 and socket 104 that indicates electric arcing is occurring between the pins 106 of the plug 102 and the electric contacts of the socket 104.
  • the region of the plug 102 and the socket 104 may comprise for example at least one of the electrical contacts of the socket 104, the pins 106 of the plug 102, the housing 110 of the plug 102 or the cover 112 of the socket 104, depending on for example the change that is being detected and/or the detection technique used, as will be discussed further.
  • the sensor 108 may comprise for example a heat sensor 108, arranged to detect whether the temperature of the region of the plug 102 and socket 104 rises above a threshold value.
  • the region may be for example at least one of the pins 108, all or part of the plug housing 110, the socket holes 107 and all or part of the socket covering 112.
  • the rise in temperature may be due to arcing taking place and/or because of overheating of burnt out/faulty electrical contacts or pins 106.
  • the heat sensor 108 is shown on or in the housing of the plug 102. Alternatively or additionally, the heat sensor 108 may be located inside the plug 102, on the socket 104 or inside the socket 104.
  • the sensor 108 may comprise a light sensor 108, arranged to detect whether the light level of the region of the plug 102 and socket 104 rises above a threshold value.
  • the region of the plug 102 and socket 104 may for example be the space between the pins 106 of the plug 102 and the electrical contacts within the socket holes 107. Such a space may arise for example because of poor fitting of the pins 106 in the socket holes 107 or because for example the pins 106 have not been fully inserted into the socket holes 107.
  • the light sensor 108 detects the light level of the region as being above a threshold value.
  • the light sensor 108 is shown as being located on or in the plug 102.
  • the light sensor 108 may alternatively be on or in the socket 104.
  • the light level in the region may increase because of a spark occurring between the pins 108 and the electrical contacts within the socket holes 107.
  • the sensor 108 may in one example be arranged to constantly monitor the region of the plug 102 and the socket 104, thereby enabling action to be taken to prevent electric arcing when factors such as the light level or temperature are determined as being above a threshold. In another example, the sensor 108 may be arranged to activate or trigger only when factors such as the light level or temperature of the region of the plug 102 and the socket 104 increase above a threshold value.
  • the plug 102 may comprise one sensor 108, for example a heat sensor 108 or a light sensor 108, and the socket 104 may comprise another (different) sensor 108, for example a light sensor 108 or a heat sensor 108 respectively.
  • both a heat sensor 108 and a light sensor 108 may be provided in the plug 102 or the socket 104.
  • the heat sensor and the light sensor may be provided as separate items or as a unitary sensor.
  • a mechanism (not shown) is activated to cause the pins 106 to be withdrawn from the electrical contacts of the socket holes 107.
  • the mechanism comprises a biasing arrangement for withdrawing the pins 106 from the socket 104.
  • the biasing arrangement may for example be or include a spring system.
  • the plug 102 comprises a mechanism for pulling the pins 106 into the plug 102 when electric arcing is detected between the plug 102 at the socket 104.
  • the plug 102 has a sensor 108 for detecting a change in the region of the plug 102 and the socket 104.
  • the plug 102 also has a mechanism for withdrawing the pins 106 from the socket 104.
  • the mechanism may be arranged such that in a default position the pins 106 protrude from the plug 102.
  • the plug 102 is arranged such that when the sensor(s) 108 indicates that arcing is taking place, the mechanism is activated to extract the pins 106 from the socket 104 and into the body of the plug 102.
  • the plug 102 having withdrawn the pins 106 away from the socket 104, is able to fall away from the socket 104, thereby reducing the chance of damage to the plug 102 and/or socket 104 by electric arcing.
  • Figures 3A and 3B show another example of the plug 102 and socket 104 in use, wherein the mechanism to cause the pins 106 to be withdrawn is contained in the socket 104.
  • the mechanism is arranged such that when electric arcing is detected the pins 106 of the plug 102 are pushed out of the socket 104.
  • the sensor 108 detects the temperature and light level of the region between the plug 102 and the socket 104 as being above the threshold heat and light values respectively
  • the mechanism pushes the pins 106 of the plug 102 out of the socket 104.
  • the plug 102 is free to fall away from the socket 104, thereby reducing or eliminating damage to the plug 102 and/or socket 104 by electric arcing.
