Definitions

  • the bonding force between the bulb and its base or socket or support for electrical contacts is a magnetic attraction force between a part provided at the bottom of the receptacle of the base, socket, support or other, and another part arranged on the rear face of the base of the bulb, said parts being susceptible of magnetic attraction , said base and the socket having corresponding centering structures allowing the orientation and the passage of the electrical contacts.
  • a metal strip or plate 13 capable of being attracted by the magnetic part 9 or any other equivalent.
  • the base is attracted to the bottom of the receptacle by the force of the magnet on the bar or metal plate 13.
  • the pins 5 and 6 of the bayonet bulbs which will cooperate with guide structures in the form of longitudinal grooves 14 and 15 provided in the walls of receptacle 3 or any other equivalent.
  • FIG. 1 an extension 16 in a hollow or full body 17 of generally cylindrical shape with a lateral surface shaped in thread 18 adapting perfectly to a conventional screw socket 19.
  • the body 17 will hang on its base 20 a central stud 21 electrically connected to the contact 7 and pressing on the tab 22 of the socket bottom.
  • the other contact is made at the level of the inlet neck 23 of the socket connected in principle to the electrical neutral of the sector.
  • the hollow body has on its outer shoulder 24 a similar contact piece, for example an annular 25, connected to the other contact 8.
  • FIG. 2 There is then distinguished (FIG. 2) an extension 16 shaped as a cylindrical body 26, the lateral surface of which is provided with two transverse pins. centering 27 and 28 diametrically opposite, engaging in the notches 29 and 30 of a conventional socket 31 with bayonet.
  • An intermediate socket has thus been produced which is mounted on the conventional socket with screw or bayonet like a bulb.
  • This intermediate socket remains permanently part of the bulb holder support.
  • the receptacle 3 constitutes the housing for holding the base 4 of the bulb without an intermediate part like a complete socket.
  • the bottom of the receptacle has contacts 36 and 37 separated by a central magnetic piece 38, for example a magnet stuck in a central housing 39.
  • the contacts 36 and 37 are connected to pieces for holding the incoming wires, for example wire clamps 40 and 41.
  • a possible protective cap 42 can be provided at the rear with an outlet, for example with a grommet 43.
  • the pins 5 and 6 may be constituted by the ends of the bar or metal plate 13 which would extend sufficiently beyond the limit of the side wall of the base 4.
  • bars 13 of circular section Figure 3
  • the invention also includes a socket 63 or an adaptation piece 64.
  • the socket 63 has a complementary receiving shape forming a cavity or a housing 65 in which is fitted the base of the bulb.
  • the general shape of this housing is that of a cylindrical cavity whose lateral surface has one or two planes 66 and 67 opposite parallel to the axis 68 of the cavity 65 corresponding to the flats 46 and 47.
  • the contacts are retained by a mechanical force, for example lateral pressure, in particular a pressing or pinching force acting on either or on one or the other of the faces of the contact parts of the bulb, for example lamellae 55 and 56.
  • a mechanical force for example lateral pressure, in particular a pressing or pinching force acting on either or on one or the other of the faces of the contact parts of the bulb, for example lamellae 55 and 56.
  • This gripping force is provided by complementary contact pieces 70 and 71 shaped as clamps, provided in correspondence at the bottom of the socket 63 or of the adaptation piece 64 on either side or of the central part of a magnet or a magnetized part 72, for example parallelepiped or cylindrical, occupying the majority of the surface of the bottom of the socket.
  • the end edges 82 and 83 of the two jaws are bent outward.
  • the inflection zone 84 and 85 causes the gradual spacing of the jaws, facilitating the penetration of the bead-shaped end.
  • the blade shapes are those derived from the pliers described above.
  • the contact pieces carried by the base 45 of the bulb can be of the cylindrical type, for example rods such as 92 and 93 solid or hollow pluggable into corresponding sockets 94 and 95 split, slightly pinch effect.
  • the shapes shown relate to two basic variants.
  • the strength and the quality of the electrical contacting are determined by the magnetic attraction.
  • the magnetic force is sufficient for the socket to catch the base of the bulb after insertion. Only the characteristics of the magnet determine the force of attraction towards the electrical contact.
  • the improvement of the magnetic retention is provided mainly by the mechanical assistance coming from the shape of the contacts.
  • Two magnets can also be adopted, one in the socket 63 or the adapter piece 65 and the other on the base 45.
  • the present bulb has contacts 101 and 102 shaped in lamellae such as 103 as well as in the central part of the base, a magnetic attraction piece 104 of smaller surface embedded in the mass of the base.
  • the base piece 106 has a body 107 of generally external shape identical to the base of conventional screw bulbs, that is to say with central stud 108 and with lateral screw surface 109.
  • the base piece 106 has an inlet housing 110 of complementary hollow shape to that of the base 45, that is to say with a cylindrical lateral surface 111 with two flats 112 and 113.
  • the inlet housing 110 has a flat bottom 114 comprising in the central zone, for example embedded in the mass, a piece 115 of magnetic attraction.
  • This base piece like the previous ones, has recessed contacts 116 and 117 under slots or openings 118 and 119 arranged in the extension of the flats 46 and 47, that is to say in correspondence with the lamellae 103.
  • These recessed contacts may take various technical forms, for example pliers.
  • the new so-called integrated socket 105 shown in FIG. 24 allows the bulb to be admitted directly. It is of the same type as that described above.
  • It has a body 120 of generally cylindrical shape with a curved end 121 from which an electrical cord 122 emerges.
  • the body has an inlet housing 123 with opposite flats 124 and 125 and an integrated bottom 126 having an attraction piece 127 and below the flats, recessed electrical contacts 128 and 129 .
