Definitions

  • the present invention relates to a safety contact plug for electrical appliances to be connected to a mains socket, with a moulding for receiving and fixing contact pins for the current conductors, comprising a connection portion for the earthing conductor, which is provided with a shape in such a way that any individual small break-away wires disappear so as to form a safe module.
  • any possibility to generate earthing leakages should be given major importance and is to be seriously dealt with as earthing leakages may cause damage not only in terms of the damage done to electrical appliances but also in terms of the risks human beings may be subject to.
  • the technical field of the present invention is still subject to improvements in order for researchers to render the earthing line free of risks to the extent that no human being gets electric shock and no appliance is damaged by a leakage current caused by the earthing line and explicitly by the connection structure provided in between the earthing conductor and the conductor ends. Accordingly, the present invention concerns elimination of such risks, mainly those posed by earthing connection within an electrical plug and is intended to bring further measures over prior art to ensure safe connection of the protective conductor ends to the earthing conductor.
  • connection bush having a conical through bore aligned with the connection bush.
  • the connection bush may be formed integrally for example so as to comprise a bridge leg into which the conductor ends are inserted. Accordingly, the insertion section is mostly constructed as a head part, aligned coaxially with respect to the connection bush and is provided as a common bridge element, supported by one arm of the body of the plug bridge.
  • the present invention brings extra measures to encage earthing wires not only in the region of the insertion section, but also within the earthing conductor into which earthing wires are extending. Accordingly, the present invention is advantageous over prior art in the sense that the head portion of the earthing conductor both reflects a simpler design making use of less material to be more suitable to automated production and brings extra measures to encage earthing wires not only in the region of the insertion section, but also along the internal part of the earthing conductor in which earthing wires lie.
  • One of the objects of the present invention is to ensure safe connection of the conductor ends to the hollow cylindrical earthing conductor so as to render the earthing line free of disconnection risks.
  • Another object of the present invention is to improve operation safety of the earthing line not only in terms of the measures taken on the head portion of the earthing conductor where the conductor ends are fixed with the earthing element but also in terms of the measures taken along the longitudinal body of the earthing conductor itself.
  • the objects of the present invention are achieved through use of a set arrangements, each concerning different portions of the earthing conductor into which protective conductor ends are inserted. Fixation of the earthing wires within the earthing conductor, is supported through a plurality of annular grooves positioned parallel along the body of the earthing conductor. These grooves, when the earthing wires are pressed together with the cylindrical body of the earthing conductor, prove to ensure safe connection so as to prevent the latter from sliding or moving outwardly in the longitudinal body of the earthing conductor.
  • the present invention presents a very simple approach to eliminate disconnection risks in the head portion of the earthing conductor without making use of extra material in the same region.
  • a safety plug for electrical devices having a pair of metallic contact pins (13), which can be plugged into a mains socket, with a plug body having a moulded part with a bridge leg (15) and the main sections (12, 17).
  • the plug-in contact bridge has a reverse "U" shaped body (Fig. 2, 11) receiving line conductors for the current leads and the earthing lead with a hollow cylindrical earthing conductor (14).
  • the ends of the earthing wires are stripped at one end and electrically coupled to the earthing conductor (14) for the protection lead, which is coupled to an earthing spring (19) fitted around the plug body, with the contact bridge and the end of the supply line enclosed in a plastics moulding.
  • the conductor ends of the earthing wires are plugged into the earthing conductor (14) and firmly connected thereto by means of a connection structure between the earthing conductor (14) and the wire ends such that once the wire ends are inserted into the bore surrounded by the body (11) of the earthing conductor (14), the earthing conductor (14) is mashed and the wires are fixedly attached to the conductor (14) as they protrude towards the cavities (20) in the pressed form.
  • the earthing conductor (14) is designed to have a small amount of taper (18), which assist in guiding the ends of the earthing wires into the same.
  • the taper (18) is applied to the outermost part (18) of the hollow cylindrical earthing conductor (14), which is made of sheet material being bent around a roller.
  • the edge parts of the sheet material, which form cylindrical earthing conductor (14) body, are tapered so as to guide earthing wires into the earthing conductor (14).
  • the outermost part of the erthing conductor (14), which forms the aperture (16) into which earthing wires are inserted is provided with a semi-conical insertion structure or a connecting socket for the earthing wires. Since said semi-conical aperture (16) is constructed as a head part being aligned coaxially with respect to the earthing conductor (14), small individual wires of the earthing bundle are securely guided in and held in the earthing conductor (14).
  • the present invention therefore presents a very simple approach to eliminate disconnection risks in the head portion of the earthing conductor (14) without making use of extra material in the same region. Since this approach is more suitable to automated production and more advantageous in that it requires less material to have the same technical effect compared to prior art arrangements, the production of the plugs can be simplified and the electrical safety can be improved at the same time.
  • the hollow cylindrical conductor (14) which is made of sheet material and bent around a roller, is first provided with a plurality of consecutive grooves (20) prior to bending operation, with the grooves (20) being set one above another along the longitudinal axis of the earthing conductor (14).
  • these annular grooves (20) prove to ensure safe connection so as to prevent the latter from sliding or moving outwardly in the longitudinal body of the earthing conductor (14) for the reason that the earthing wires being pressed in the cylindrical body of the earthing conductor (14) engage in the grooves (20) and provide an extra retention force and improved electrical safety within said body.
