Definitions

  • the invention relates to an adaptation device placed between one of a multiplicity of contactor devices having coupling members performing separate strokes from which it receives a first movement and an auxiliary switch box which is associated to this device for receiving a second movement and which has movable contact parts having a working stroke less than or equal to the previous ones.
  • This device is suitable when, for a given overall size thereof, certain proportions between the input movement and the output movement must not be exceeded.
  • the contactors are called upon to execute working strokes which increase with the size of the currents passing through their main switches.
  • the strokes of the auxiliary switches intended to operate electrical interlocks and to retransmit comparable signals are similar, since the loads which they supply always have similar characteristics.
  • one of the possible solutions to this problem may consist in the supply of a range of custom-made auxiliary switch devices for the range of corresponding contactors, such a choice is likely to unnecessarily increase the various technical manufacturing costs and management arising from the manufacture of a multiplicity of molds, the management of stocks of multiple parts, etc. Furthermore, it also involves the publication in catalog and the provision of a set of devices including neighboring external forms may cause confusion for the user.
  • the invention therefore proposes to overcome the drawbacks of the prior means and to provide users with an adaptation device which will allow mounting on any contactor device of a range, auxiliary switch devices having the size and minimum working strokes required for a combination of these with a contactor device whose nominal rating is the lowest in the range.
  • the aim is achieved thanks to the fact that in an envelope of the adaptation device, having suitable indexing means with the body of the associated contactor, is pivoted a transmission lever having, on the one hand , an arm which is provided with a groove in S shape to cooperate with each of the coupling members and having, on the other hand, an external coupling claw adapted to be associated with a control slide belonging to an auxiliary switch, this groove comprising, between two portions of non-aligned ends, an intermediate connection portion of which the length and the orientation are sufficient to communicate to the lever a tilting capable of giving the claw a determined displacement for a fraction of the working stroke of the contactor having the working stroke the highest in the range.
  • association claw is accessible when the intermediate device is already associated with the body of the contactor, a replacement of the auxiliary switch devices can then be easily operated without the need to disassemble the adaptation device.
  • a widening of the functions of the adaptation device can be obtained by means of the installation of several levers in order to have two claws capable of thus actuating a couple of auxiliary devices which can perform distinct functions such as, for example, closing and instantaneous or delayed opening of auxiliary contacts.
  • a large-caliber contactor device 1, visible in FIG. 1, includes an internal electromagnet whose non-visible movable armature performs a certain stroke during its excitation and de-excitation.
  • a lateral coupling member such as a pin or stud 2, being connected directly or not to this armature simultaneously performs a substantially rectilinear displacement of direction F which is exploited to cause the switching of associated auxiliary switches such as 3 which are , in the context of the present invention, generally intended to be combined with contactors of lower ratings.
  • auxiliary switches whose stroke of the moving parts is substantially less than the previous one, could not be coupled to this pin without the putting into service of an appropriate adaptation device such as 4.
  • auxiliary switches such as, for example, a timed switch 5
  • auxiliary switches can also be combined with the contactor 1 thanks to this same adaptation device when their sizes and the strokes of their moving parts were also initially designed as part of an association with a contactor of lower rating.
  • the adaptation device 4 comprises a hollow envelope 6 in which are symmetrically pivoted concentrically about an axis YY ′ two levers 7, 8 substantially identical, but turned 180 °.
  • the pivot can advantageously be materialized by a cylindrical rod coming from a part with the envelope.
  • Each of the levers such as 7 comprises two perpendicular arms 9, 11 on either side of the common pivot 12, one of these 9 having a claw 15 respectively 16 for example in the form of a dovetail, while the other has a light 20 respectively 30.
  • the latter takes the general form of an S, two end portions 17, 18 of which are connected by an intermediate central portion 19.
  • This lever can oscillate by a value - alpha -, during a movement whose origin will be described later, and whose amplitude is such that the claw 15 can, for example, engage a certain amount in the internal volume 21 of the envelope for an extreme working position - T -, see FIG. 3, while it protrudes by another quantity - e - the surface 22 of the envelope for an opposite extreme position of rest - R - through an opening O, see Figure 1.
  • the bottom 23 of the casing 6 has a notch 24 opposite which come the ends 25, 26 of the two levers, while a side wall 27 has two holes 28, 29 placed so precise with respect to the axis XX ′ and with respect to a central oblong opening 31 directed towards this axis.
  • This oblong opening has a length - d - which is at least equal to the stroke that the coupling member 2 which can cross it can make when the envelope is precisely associated against the lateral face 32 of the contactor device. .
  • the precision of this association which is obtained here thanks to two openings, threaded on this wall such as, for example, 33, 34, see FIG. 1, receiving fixing screws which circulate through the holes 28, 29, can also use other indexing means well known per se.
  • the substantially straight stroke of the coupling member 2 is less than the total length of each light so that for each of the rest positions - R - and work - T - clearances - j1 - and - j2 - remain at both ends thereof for said active and inactive positions of the contactor.
  • the angular displacements of the levers occur when the coupling member 2 circulates in the intermediate portion 19 inclined which connects the two non-aligned portions and substantially rectilinear ends.
  • the coupling member When, during assembly, and therefore for the de-energized state of the contactor device, the coupling member must be introduced into the two lumens of the levers, these can be moved manually through the notch 24 so that s 'more easily establish an alignment allowing this introduction.
  • the claw 15 engages around a suitable extension 45 belonging to a control rod 46 of the auxiliary switches, to communicate to the latter a determined movement - b - substantially constant.
  • auxiliary switches I1, I2 must perform electrical locking functions, as is the case, for example, in direction-of-travel reversing arrangements for three-phase motors, where it is necessary to prevent overlapping of the periods d 'excitation of the two corresponding electromagnet coils, these two switches can not have simultaneous closing phases.
