Definitions

  • Such devices can be used, either when the environment in which they are found has any aggressive character (acidity, humidity, dust), or even when one wishes to reduce the harmful and inevitable influence of oxygen on the contacts, even when the surrounding atmosphere is normal.
  • the invention proposes to provide an electrical switching device of the aforementioned type in which money is not used for the materials of the contact pads of the switches and to provide inexpensive means for keeping in the atmosphere which surrounds them with non-aggressive properties for the chosen materials.
  • this device is characterized in that the contact pads of the switches are essentially based on copper materials, while the atmosphere confined under the protective cover has and retains a non-oxidizing character, thanks to means of 'sealing of particular shape, which are placed between, on the one hand, the frame and a first face of the body, on the other hand between the cover and a second face of the body opposite to the first.
  • the apparatus 1 comprises a body 2 of electrically insulating material of generally parallelepiped shape having a lower face 21 under which there is an electromagnet 11 constituted by a fixed magnetizable yoke 7 formed by the association magnetizable parts 3, 4, 5, 6, an excitation coil 10 comprising a carcass 8 having a bore 13 and a winding 9, and a magnetizable movable armature or core 15 preferably of cylindrical shape which is subjected to the action a return spring 14 giving it a visible rest position in Figure 1.
  • a support la is fixed to the magnetizable part 4 to fix the device to a frame.
  • the magnetizable part 3 fixed under the body 2 has an opening 16 through which passes the cylindrical part 17 of a bowl 55 which is non-magnetic and made for example of brass and which serves as a housing for the core 15 and the spring 14.
  • the bottom 18 of this bowl is placed in the immediate vicinity and preferably against the upper surface 19 of the magnetizable part 5. This bottom simultaneously serves as an anti-remanence gap of the electromagnet.
  • the upper edge of this bowl 55 is extended outwards by a flat collar 20 (see FIGS. 1 and 3) which rests on the upper surface 12 of the part 3 and which is applied by the latter against the lower surface 21 of the body 2.
  • a groove 22 receiving an elastic seal 23, for example an O-ring, which is compressed by the flange 20 when the part 3 is fixed against the surface 21 of the body 2 by means, not shown, such as screw, so that a tight connection is made between the body 2 and the interior volume of the bowl 55.
  • an elastic seal 23 for example an O-ring
  • a housing 24 which serves as a stop for the core 15 and which opens into an axial clearance 25 which passes through the body 2 , in which is mounted an insulating contact carrier 26 which extends above the body 2 by several parallel branches, the number of which corresponds to the number of switches arranged above the body 2.
  • Each of these branches such as the branch 27 has (see FIG. 2) a window 60 in which is placed a contact bridge 28 and a contact pressure spring 29 (see FIG. 1) which applies it towards the core 1 against the bottom of this window 60.
  • each fixed contact piece 34 or 35 has a cylindrical intermediate portion such as 39 which is placed in a cylindrical cavity or half-housing such as 40 provided in the upper surface 41 of the body 2. (See FIG. 6).
  • This edge of this cover 42 adjacent to the surface 41 of the body has a plane peripheral rim 43 perpendicular to the side walls of the cover.
  • This peripheral rim 43 comprises several cavities or cylindrical half-housings such as 44 (see FIG. 5) which are arranged opposite the cylindrical half-housings 40 to form, when the cover 42 is mounted on the body 2, a complete housing receiving the cylindrical intermediate portions 39 of the contact parts 34, 35 (see FIG. 6).
  • This seal 47 is molded in one piece from an elastomeric material and has as many toric parts as 48 perpendicular to the rectangular loop of the seal, that the device comprises fixed contact parts 34, 35, the intermediate portions 39 of these coming to be inserted in said toric parts 48.
  • This seal 47 advantageously finds its place in grooves such as 51, 52 (see FIG. 6) formed both on the portions of flat faces 45 of the rim 43 of the cover 42 and on the cavities 40 of the upper surface 41 of the body 2 so to undergo a measured compression when the cover 42 is mounted on the body 2.
  • Special O-rings such as 49 can also be placed in the half-housings 40, 44 around the intermediate cylindrical portions 39 of the fixed contact parts so that they can be compressed during assembly, like the seal 47 in order to perfect sealing.
  • the cover 42 which advantageously has internal isolation partitions such as 50 (see FIG. 2) for separating two neighboring switches 54, 53 can be filled with a particular atmosphere thanks to one or more orifices capable of being closed, but not represented.
  • Such an atmosphere can be either vacuum, or a mixture in any proportion of non-oxidizing gases such as N 2 , H 2 ' Ar, He, or even an atmosphere containing electronegative and dielectric gases such as SF 6 , CF 4 , CC1 4 or a mixture thereof with non-oxidizing gases.
  • the body 2 can be made either of a plastic material, or of a ceramic material, the surfaces of which having to cooperate with the seals 47, 49 will advantageously be machined, in particular rectified after molding.
  • the device 1A includes a protective cover 42, switches, and an upper surface of the body identical to those of the device according to Figures 1 to 6. These parts are therefore designated by the same references.
  • the electromagnet and the contact holder of the device 1A are different.
  • the contact holder 82 visible in FIG. 7 has, like that of the apparatus 1 shown in FIGS. 1 and 2, parallel branches 62 each carrying a contact bridge 28. These branches which pass through openings such as 64 are connected by a cross 66 which is placed in a housing 81 where the openings open, and which has an extension 63 beyond this housing.
  • An intermediate region 83 of this extension has on its outer surface a groove 67 advantageously annular which receives one of the ends 68 of a deformable cuff 69 made of elastomeric material, this end preferably being held in this groove 67 by a collar of tightening 74; the other end 70 of this cuff 69 has a bead 71 which is pinched between a lower surface 72 of the body 65 and a flange 73 which surrounds this cuff. This flange 73 is for example fixed on the lower face 72 of the body 65.
  • the deformable cuff 69 consequently provides the seal between the body 65 and the contact carrier, so that the switches such as 36 are placed in a closed volume completely sealed from the outside and in which a non-oxidizing atmosphere is permanently maintained.
  • the contact pads 30, 31, 32, 33 copper-based materials, much less expensive than silver.
  • the electromagnet 80 used in this device comprises a movable armature 75 which is made integral with the extension 63 and which cooperates with an E-shaped cylinder head 76 whose central branch 77 is surrounded by an excitation coil 78.
  • a spring return 79 gives the frame 75 and therefore the contact carrier 62 its rest position, the cylinder head 76 being made directly or indirectly integral with the body 65.
  • the electromagnet 80 is therefore in this second embodiment completely external to the volume contained between the protective cover 42 and the sleeve 69, and can be supplied directly from an alternating current source, the presence of rings of phase shift requiring zero air gaps at their level between the plane rectified parts of the movable armature 75 and of the cylinder head 76.
