Definitions

  • the present invention relates to an electrical coupling, in particular but not exclusively, an electrical coupling adapted to provide an electrical connection between an electronic device and an electricity source.
  • the invention relates to an electrical battery having an electrochemical cell.
  • An electrical battery typically includes a housing holding one or more electrochemical cells.
  • chemical energy is converted into electrical energy.
  • Batteries generally have exposed terminals to facilitate electricity flow to electronic equipment. If such terminals are connected / bridged out by (i) an intermediate object, or (ii) water, the battery is short-circuited, resulting in heat being emitted and energy discharged. This could result in the battery being destroyed and a device housing the battery being severely damaged. In an extreme scenario a short-circuited battery could cause a fire.
  • button cells Many electronic devices use small, round, flat batteries known as button cells or button batteries. It often happens that unattended young children swallow such button batteries. A swallowed button battery can become short circuited by bodily liquids causing serious burns to a child's internal organs and, in severe instances, leading to death.
  • Power points and light sockets generally include cavities respectively for receiving electrical plugs or light bulbs. Though power points around the world may have different shapes, they all include a configuration of holes which accept a dedicated configuration of prongs. With the prongs inserted into a power point electricity flows from the electricity mains of a building to an appliance plugged into the power point. Should a person, for example an inquisitive young child, insert a metal object into holes of the socket the person could be electrocuted.
  • Various light bulbs include different types of sockets, for example an Edison thread or bayonet cap socket.
  • sockets include live terminals for conducting electrical current to a light bulb coupled to the socket. A person touching those terminals with, for example, a finger could be electrocuted.
  • Rechargeable electronic devices are configured with a recharge socket, cradle or plug system to allow the device to be recharged. Recharge systems generally are not moisture resistant. This results from having an open socket for receiving a connecting recharge pin. An open socket could provide an access point for moisture ingress. To address this problem waterproof plugs are provided for closing off the recharge socket. Such plugs, however, tend to be costly and cumbersome to use.
