Definitions

  • the present invention relates to an arrangement with an electric coil, in particular an electromagnet, of the type comprising a coil carcass, which comprises a cylindrical body carrying the coil and, at each end a flange, a coil cover in the form of a sleeve. enclosing said coil coaxially and a device for connecting the arrangement, which comprises connection lugs anchored in one of said flanges and each provided with a pin connected to the coil and with an external connection pin and a plug connection including connection plugs.
  • Electromagnets of this type are already known. Their external connection pins are connected to one end of conductive wires which are connected at their other end to said connection socket. The wires are immobilized at their connection to the lugs on the external surface of the coil, advantageously by an appropriate adhesive tape, and leave the internal space of the electromagnet through a notch formed in the anchoring flange .
  • connection of the lugs to the socket by means of conductive wires which must be immobilized additionally with the aid of an adhesive tape has the drawback that the connection device is not compact and that its production requires a number of relatively large work operations.
  • the object of the present invention is to propose an arrangement of the type described above, which does not have not the aforementioned drawbacks.
  • connection socket is fixedly mounted on the external surface of the coil cover, at the level of the pin anchoring flange and the socket and the external connection pins are shaped so that the pins engage in the socket when the cover is put in place so as to form said connection plugs.
  • the external connection pins are folded so as to extend parallel to the axis of the arrangement, from the plane of their anchoring flange, outside the cover, and in that the socket is made in the form of a housing which has in its wall adjacent to said flange holes through which the folded pins extend inside the housing.
  • an electromagnet As shown in FIG. 1, an electromagnet according to the invention comprises a coil carcass 1 which carries the coil 2, a coil cover 3 which coaxially surrounds the carcass 1 and a device 4 for connecting the coil 2 to external connector wires (not shown).
  • the carcass and the cover are made by plastic molding.
  • the reference numeral 5 indicates the passage of the plunger core (not shown) of the electromagnet.
  • the reference 6 designates elements of the armature of the magnetic circuit of the electromagnet.
  • Figures 2 to 4 show the structure of the coil carcass 1.
  • This comprises a cylindrical body 8 on which the coil 2 will be wound and which carries its ends of the flange-shaped cheeks 9 and 10.
  • the cheek 9 is designed to allow the installation and anchoring of two connection lugs 11 which provide the electrical connection of the coil 2 to the connection device 4.
  • a terminal 11 is produced in the form of a flat element of the general shape of a U, the branches of which constitute connection pins 12 and 13 and which bears at its base an anchoring foot 14.
  • This is of generally rectangular shape and has at its free end hook-shaped elements 15 having sharp angles 16 lying substantially at the level of the substantially parallel lateral edges of the foot. These sharp angles ensure the anchoring of the terminals, as will be explained below.
  • the connection or contact pins 12 and 13 have different lengths.
  • the shortest pin 12 is connected to the coil 2, as schematically indicated in 18, while the terminal 13 has a relatively large length allowing it to constitute one of the contact plugs of the connection device 4, as is apparent from the Figure 1.
  • pins 12 and 13 which are inside the cheek 9 of the carcass have a greater width than the ends, which gives the pods great rigidity.
  • the pin 13 is folded at the level of the sudden change in width at 19.
  • the contact lugs are advantageously made of tinned brass.
  • the cheek or flange 9 has two cavities 20 at the connection device 4 which are symmetrical with respect to the axis YY (FIG. 4).
  • Each cavity has a shape substantially complementary to the base of a contact terminal 11 and for this purpose comprises a part outer whose width corresponds to that of the base of a terminal and a narrower internal part of rectangular shape having a width corresponding to that of the anchoring foot 14 of the terminal, so as to allow the introduction of this base and to make impossible or very difficult a subsequent withdrawal due to the sharp angles 16 of the foot.
  • the terminals 11 are placed in such a way that the pins 13 are located adjacent to the axis YY.
  • a protective rib 23 On the side of the cheek 9 where the cavities 20 open and, laterally offset towards the outside relative to the latter, rises a protective rib 23 whose upper edge is at the level of the zone 19 where the contact pin 13 is folded perpendicular to its implantation part in the cheek.
  • the width of this rib is slightly greater than the distance from the outer lateral edges of the two lugs 13, as shown in FIG. 2.
  • This cover consists of a sleeve whose shape corresponds to that of the cheeks 9 and 10 of the carcass, that is to say that 'It is of substantially rectangular shape.
  • This sleeve coaxially surrounds the carcass 1 with its coil 2 and carries on its outer surface at the terminals 11 a structure 25 which forms the housing of the connection device 4 and is of generally parallelepiped shape.
  • This box is opened at 26 towards the center of the sleeve.
  • the opposite outer wall 27 has passages 28 which extend parallel to the axis of the sleeve and allow the passage of the folded parts 24 of the pins 13 of the lugs 11 as illustrated in FIG. 1.
  • This figure also shows that the wall 27 is arranged so as to leave uncovered the outlets of the cavities 20 for installing the terminals 11.
  • the side walls 29 and the wall upper 30 of the housing 4 extend beyond the wall 27 and delimit a space 31, which, when the cover or sleeve 3 is in its position for covering the coil 2 houses the part of the lugs leaving the carcass, and is closed towards the outside by the protective rib 23 of the carcass.
  • the assembly of the carcass 1 and the cover 3 makes it possible to obtain an arrangement in which the connection device is compact.
  • the lugs 11 by their pin 12 provide the electrical connection to the coil 2 and by their longer pin 13 constitute the plugs of the connection socket of the device 4.
  • To the advantage of the compactness of the structure is added as another major advantage the simplicity of the assembly of the assembly.
  • the folded portions 24 of the lugs will then extend through the passages 28 of the wall 27 of the housing towards the interior of the latter so as to be able to form the plugs of the connection device.
  • the passages guide and maintain the cards.
