Definitions

  • the present invention relates to a device for actuating electrical contacts comprising an electromagnet, a bistable control mechanism of at least one electrical contact and means for transmitting the movement of the electromagnet to this mechanism.
  • the present invention proposes to overcome these drawbacks by providing a device compact, space-saving, reliable, easy to assemble and made up of simple parts realize and inexpensive.
  • the electromagnet is a plunging core electromagnet and in that said means for transmission of the movement of the plunging core to said mechanism comprise a sword coupled on the one hand to said plunging core and on the other hand to a pivoting barrel, mounted on a fixed axis of rotation, this sword being disposed externally at the electromagnet between the head of the plunging core and the barrel.
  • the barrel has a recess with a profile cam and said sword has a lateral stud at its free end, this stud being engaged in said cam profile recess of said barrel.
  • the sword is advantageously articulated at its end opposite to said lateral stud on a transverse axis secured to a cap mounted on the head of the plunging core.
  • said cam profile recess comprises a first hollow and a second hollow, these hollows being arranged to alternately house said lateral nipple and serve as supports for passing said barrel from one to the other of its stable positions.
  • said cam profile recess has a face guide which connects the two recesses and is arranged to guide the stud lateral when the plunging core and the sword linked to it return to its position initial.
  • said cam profile recess defines a cam closed for said lateral nipple of said core movement transmission sword dipping into the control mechanism.
  • the device actuator 10 is associated with a contact block 11, for example a remote control switch or similar.
  • the contact block 11 comprises a housing 12 in which are mounted switches 13, for example four in number, which are actuated by a bar 14 movable axially.
  • This bar 14 can occupy a high position represented by figure 2 or a low position, depending on the state of the device actuation. In the high position of the strip 14, the switches 13 are closed, while the low position corresponds to the opening of the switches.
  • the strip 14 is coupled to the contact actuation device 10 by means of a connecting piece 15.
  • This contact actuation device 10 essentially comprises an electromagnet 16 with plunging core 17, a bistable control mechanism 18 of the movable bar 14 which actuates the switches 13, and transmission means of the movement comprising a sword 19 which provides the mechanical connection and the transmission of the movement of the plunging core to the control mechanism bistable.
  • the electromagnet 16 has an armature 16a which supports the carcass 16b of a coil.
  • the plunging core 17 is arranged to slide inside a channel guide formed by said carcass 16b of the coil. It is surmounted by a cap 20 mounted on the head of the plunging core and on which the sword of transmission 19, mounted on a transverse axis 21 integral with the cap 20.
  • a return spring 22 is arranged around the plunging core, in its upper part which exceeds the guide channel of the electromagnet coil frame, or around an extension of this nucleus.
  • the transmission sword 19 can pivot on transverse axis 21.
  • the bistable control mechanism 18 mainly consists of a barrel 23 pivoting mounted on a fixed axis of rotation 24 on which it can rotate freely.
  • This barrel is coupled to a link 25 which is articulated on a fixed axis 26.
  • the coupling mechanical between the barrel 23 and the link 25 is effected by means of a stud 27 engaged in an oblong opening 28 formed in the link 25, this stud being designed to slide freely in this opening.
  • a compression spring 29 is mounted on the link so as to bear on the one hand against a fixed stop, in this case the connecting piece 15 which constitutes a fixed support, and on the other hand against the barrel 23 which constitutes a mobile support.
  • the barrel 23 has a recess with a cam profile 30, in which is engaged a lateral pin 31 disposed at the free end of the transmission sword (see FIG. 3). This nipple allows to couple this sword permanently with the barrel.
  • FIG. 4A represents an initial position of the transmission sword 19, this position corresponding to an initial position of the bistable control mechanism 18 as shown in Figure 5A. This position is stable because the spring of compression 29 tends to block the barrel in the position shown where the stud 27 abuts against the end of the oblong opening 28 opposite the fixed axis 26 of pivoting of the link 25.
  • the plunger is attracted to the inside of the coil casing and the movement transmission sword 19 moves in the direction of arrow A.
  • the point of this sword which carries the lateral pin 31, moves along the axis D1 until it arrives at abutment against the bottom of the hollow 32 of the cam profile recess 30.
  • the point of this sword pressing against the bottom of the hollow 32, drives the barrel and tilts it around the axis of rotation 24, in the direction of the arrow B.
  • This movement of the movement transmission sword 19 causes the mechanism to pass bistable control 18 of its first stable position represented by FIG. 5A, at its second stable position represented by FIG. 5C passing through a position intermediate shown in Figure 5B.
  • the tip of the movement transmission sword 19 occupies a position 19a illustrated in dotted lines in FIG. 4B.
  • the lateral stud 31 is in press against the bottom of the hollow 32 of the cam profile recess 30.
  • the return spring 22 removes the plunging core and moves the movement transmission sword 19 into the direction of arrow C.
  • the lateral pin 31 first bears against the face of inclined guide 33 of the cam profile recess 30 and follows this face in causing a pivoting of the sword 19 which is positioned along an axis D2, which is substantially symmetrical about the axis D1 with respect to an axis D which joins the transverse axis 21 of the movement transmission sword 19 and the axis of rotation 24 of the barrel 23.
  • the sword occupies the position shown in Figure 4B, and the bistable control mechanism 18 is in its second stable position.
  • the plunging core is at again drawn into the guide channel of the electromagnet casing.
  • the spring 22 is compressed and the movement transmission sword 19 is driven in displacement along axis D2. Its tip first engages in the hollow 34 of the cam profile recess 30 of the barrel 23, then swings the latter around its axis of rotation 24, in the direction of arrow D. This displacement has the effect of return the bistable control mechanism from its second to its first position stable.
  • the bistable control mechanism 18 comprises the barrel 23 pivoting around said fixed axis of rotation 24, said barrel cooperating with a spring hairpin 40, one end of which is hingedly connected to barrel 23 and of which the other end is connected in an articulated manner to a fixed support 41 of the housing.
  • the bistable control mechanism 18 comprises the barrel 23 pivoting around said fixed axis of rotation 24, a link 25 articulated on a second fixed axis 26 of the housing, the barrel being coupled to the link by means of a stud 27 integral with the barrel 23 engaged in an oblong opening 28 provided in the connecting rod, and a compression spring 29 bearing on the one hand, against the stud cited above 27 and on the other hand, against the link.
  • the stud 27 is integral with the rod 25 and engaged in a oblong opening 28 provided in the barrel 23, the compression spring 29 being mounted between the stud 27 and the barrel 23.
  • the bistable control mechanism comprises the pivoting barrel 23 around said fixed axis of rotation 24, a link 25 connected in an articulated manner, by one of its ends, to the barrel 23 and the opposite end of which has a oblong opening 28 cooperating with a stud 27 secured to a fixed support 41 of the housing and a compression spring bearing on the one hand on the stud 27 and on the other hand on the link 25.
  • the bistable control mechanism comprises the pivoting barrel 23 around said fixed axis of rotation 24, a link 25 articulated by one of its ends on said barrel 23 and comprising at its opposite end a stud 27 engaged in an oblong opening 28 formed in a fixed support 41 of the housing, and a compression spring 29 bearing on the one hand on the fixed support 41 and on the other share on nipple 27.
  • the device described has many advantages. It is compact and its operation is particularly safe.
  • the notches are as small as possible in order to limit the the dead stroke of the sword in the barrel is no longer possible.
