Definitions

  • the present invention relates to a multipolar switch device with electromagnetic control of the contactor type according to the preamble of claim 1. It relates more particularly to a part intended to cooperate with the movable contact carrier of such a device, as well as with the housing, so on the one hand to ensure a fixed support to the springs urging the movable contacts and, on the other hand, to define arc breaking chambers for each pole.
  • a second spring also opposes the action of the electromagnet, that is to say that it repels the movable armature when the coil is not energized.
  • the contactor is of the opening type, the actions of the two springs are added, and the electromagnet must therefore be more powerful to overcome them, thus raising the moving assembly and opening the contacts.
  • the closing force of the contacts, exerted by the first spring, exhibits a reaction absorbed by the housing by means of auxiliary parts interposed between the housing and said spring.
  • the principle thus disclosed proves to be inconvenient to implement, because the auxiliary parts are in number equal to the number of poles with opening, and they have to be mounted manually one by one in the recesses of the contact carrier.
  • the assembly time is relatively long, because it is necessary to install said auxiliary parts, then the contact pressure springs and finally the bridges of the movable contacts in the prismatic housings of the contact carrier. This repetitive operation proves to be difficult to perform due to the nature of the parts.
  • This plate is pierced with cells to allow the passage of the isolation partitions of the contact carrier, during movement of the latter when the movable frame of the electromagnet is returned to the fixed frame.
  • the plate includes "insulating skirts acting as a partition between cutting chambers in order to establish a chicane effect at the level of this".
  • the present invention goes much further.
  • Its object is to present, in a single piece, a structure allowing firstly to ensure a fixed support for the contact pressure springs of the opening poles and, secondly, to partition the arc breaking chambers for all the poles.
  • the second function consists in protecting the breaking chambers which are subjected to intense stresses due to the repeated electric arcs which occur there. These arcs cause erosion of the partitions between breaking chambers, and sudden changes in temperature which ultimately weaken the material of the partitions.
  • the bases are made of thermoplastic material, which is easy to work, but whose resistance to erosion and to high temperatures is poor.
  • the ideal would be to use a thermosetting material, very resistant and whose endurance tests prove that the resistance to sudden changes in temperature and to arc erosion is excellent.
  • such a material is difficult to transform. Manufacturing costs are therefore higher.
  • the objective of the invention is to solve this problem by proposing a single so-called auxiliary part made of a durable material, which simultaneously performs a lateral partitioning and of the face opposite the base of each breaking chamber. As said, this part also allows a fixed support for the contact pressure springs of the opening poles.
  • said recesses of the movable contact carriers have only one housing per pole for the movable contact bridges, which are identical, as are the blades of the fixed contacts and the movable contact carrier, for both pole versions with closing and opening.
  • US-A-2 985 736 discloses a design with a single recess, but for mobile contact carriers individualized in each breaking chamber, and without connection with a fixed support plate for the springs of the opening contacts. This configuration has nothing to do with the type of design of the present invention.
  • the auxiliary part is fixed relative to the base, which allows it to perform its two functions. It is provided with an opening made in a central zone of the plate, allowing the passage of a member for holding the movable contact carrier in the movable armature of the electromagnet. This mechanical connection only becomes efficient when there is a deflection of said movable contact carrier under the effect of the forces of the springs or, exceptionally, during bonding of the contacts.
  • connection between this holding member and the movable part of the electromagnet is a dovetail connection.
  • the central position is explained by the holding function. It is not a binding, and the tolerance of the bond is therefore very wide.
  • the central support resulting from this connection compensates for said bending and maintains as much as possible the relative arrangement of the parts despite the mechanical constraints.
  • the assembly of the contactor is all the easier since the mobile contact carrier, secured at its two longitudinal ends remote from the base of the base to the manual control arms of the device, constitutes, in association with the latter as well as with the auxiliary part forming the arc breaking chambers and with the movable armature of the electromagnet, a complete sub-assembly which is placed for mounting in the reliefs provided for this purpose in the base.
  • the arms in question also provide the main mechanical connection between the contact carrier and the movable frame, by means of vertical dovetail connections.
  • the auxiliary part of the device according to the invention then fits into housings in the base provided for this purpose, and becomes integral with the housing.
  • shock absorbers preferably located at its corners, and it is also slightly movable so as to absorb the shocks caused by the sudden arrival of the movable frame.
  • dampers make it possible to attenuate the wear of the contacts, caused inter alia by the few ms of separation of the contacts during each shock on closing, for the closing poles. This brief separation and the resulting vibrations create abnormal wear that the dampers decrease.
  • the switch device of the invention comprises, in the vicinity of the cover, a manual control part provided with an operating button, and connected to the two manual control arms by means of cams having at their ends two zones. of rest for said arms in which the armatures of the electromagnet are respectively in close or distant position.
  • the rest areas are interconnected by a ramp inclined to transform the movement parallel to the base of the button base into a perpendicular movement performed by the movable assembly formed of the movable frame, the contact carrier and the manual control arms.
  • the inclined ramp has an extreme point shortly before the close armature rest point, at which the two armatures are in contact, while they are at a short distance from each other in the close rest position.
  • Said part provided with an operating button additionally comprises at least one spring member intended to exert a restoring force towards the resting point of distant armatures, which is exerted when a voltage pulse in the coil of the electro- magnet puts the two armatures in contact.
  • Figure 1 shows an auxiliary part (A) of the device according to the invention. It consists of a plate (1) on which bear the springs of the movable contact bridges of the opening poles, and partitions (2) separating the breaking chambers.
  • an opening (3) allows the connection between the movable contact carrier and the movable armature of the electromagnet.
  • This opening (3) is located between a partition (2) and a portion (2 ′) which, from the plate (1), develops in the same direction as the partitions (2), but over a much longer length. limited.
  • the partitions include ribs (4) for reinforcement, and recesses (5) intended to cooperate with the base of the movable contact carrier.
  • the auxiliary part (A) is fixed to the frame, in this case the base (S) of the housing, by means of supports (6) which fit into housings provided for this purpose in said base (S ), and are locked when the cover (C) is put on.
  • Figure 2 shows the positioning of said auxiliary part in the housing.
  • the supports (6) are located at the joint between the base (S) and the cover (C).
  • two movable contact bridges (7) are open, the other two (7 ′) being closed. They are therefore respectively in contact and separated from the blades of the fixed contacts (8) at rest, that is to say when the movable armature (9) of the electromagnet is distant from its fixed armature (10).
  • the auxiliary part (A) is not only secured to the base (S) by the supports (6), but it is also positioned using grooved reliefs (13), which provide the lower partitioning of the breaking chambers.
  • connection terminals (14,14 ′) located at the ends of the device.
  • Figure 5 shows the interpenetration between the different parts, and in particular the movable contact carrier (16) and the auxiliary part (A).
  • the part (A) has recesses (5) which adjust in width around the constrictions (17) of the base of the contact carrier (16) (see FIG. 6).
  • the height of these recesses (5) is greater than that of the base at the location of the interpenetration, so that the contact carrier (16) retains its mobility in translation.
  • the dovetail connection (20) between the movable armature (9) of the electromagnet and the contact carrier (16) is located on a central branch of the latter which passes through the plate (1) via the opening (3). It should be noted that when the cover (C) is put on, there is no contact between the auxiliary part (A) and the movable frame (9).
  • the mechanical connections (20 ′, 20 ⁇ ) armatures (9) / arms (19, 19 ′) in vertical dovetails carry out the function of securing these two elements, and consequently of the contact carrier assembly (16 ) / movable frame (9).
  • the dovetail connection (20) does not have the function of joining the two elements that it connects. It only serves when the contact carrier (16) is subjected to deflection during operation, due to the forces of the springs (11) or when the contacts are bonded. It then prevents internal deformation which can affect operation, or even cause the contact holder (16) to break.
  • the contact pressure springs (11) When the contact pressure springs (11) are in the opening configuration, they are positioned on the plate (1) by a stud (18), while they simply rest at the bottom of the housing (15) in the reverse configuration .
  • Figures 6 to 9 illustrate the steps of mounting the sub-assembly that is placed in the grooves (13) of the base (S) provided for this purpose.
  • the movable contact carrier (16) takes the form of an inverted E, whose outer branches (18, 18 ′) cooperate with the manual control arms (19, 19 ′), while the central branch (20) cooperates, as we have seen, with the movable armature (9) of the electromagnet.
  • Figure 6 shows particularly clearly the constrictions (17) around which adjust the recesses (5) of the auxiliary part (A).
  • the manual control arms (19, 19 ′), known per se, comprise the above-mentioned dovetail connections (20 ′, 20 ⁇ ) intended to adapt to corresponding housings formed in the sides of the movable frame (9) of the electromagnet.
  • the sub-assembly is then compact enough to be assembled with the rest of a single piece, as it appears in Figure 10 where it is placed in the base (S).
  • the movable contact carrier (16) is made of thermosetting material, like the auxiliary part (A).
  • FIG 11 shows the coil (21) and its carcass (22) which is placed around the central branch of the movable frame (9).
  • the coil carcass (22) is held on the base (S) by means of clips to ensure mounting despite the spring (12).
  • it includes shock absorbers intended to absorb the shock caused by the movable frame (9) when it strikes the fixed frame (10) when closed.
  • the carcass (22) is slightly movable to increase the damping effect.
  • Flexible blades (23, 23 ′) are connected to connection terminals (24, 24 ′) for supplying the coil (21).
  • the assembly is completed by the fixed armature (10) of the electromagnet (see Figure 12), and the manual control part (25) which appears in Figure 13, provided with its operating button (26) and spring bodies (27, 27 ′).
  • this part cooperates with the manual control arms by means of a cam path (30) (see FIG. 14) on which the shaft (31) moves, connecting two branches of said arms (19 , 19 ′).
  • the central position represents automatic operation (it is illustrated in Figure 15). In one direction (see arrow F in Figures 13 and 14), the contacts are controlled, while in the other direction, action is taken on the coil which is cut.
  • the contact control implies the proximity of the armatures (9, 10) of the electromagnet.
  • the button (26) By pushing the button (26) so that the shaft (31), coming from a rest position (R1), climbs the inclined plane (32), the frames (9, 10) are brought closer.
  • the shaft (31) passes through a vertex (P), then shims in a rest position (R2).
  • the spring members (27, 27 ′) are then applied against an interior surface of the cover (C).
  • the existence of the top (P) keeps the tree in the rest position (R2).
  • the contacts are closed.
  • the shaft (31) being slightly lowered, there is a small air gap between the frames.
