- the invention relates to a system for positioning and locking at least one removable electromagnetic relay 1 such as a coil on an ACB type circuit breaker 2, one end of the relay 1 carrying a connection interface 3 intended to be in contact with the homologous interface 4 of the circuit breaker, characterized in that the locking system comprises at least: on the circuit breaker 2: • a receiving interface 51 having a substantially flat surface and comprising at least one through opening 6 configured to be crossed by the connection interface 3 of the relay 1,
- a locking plate 52 positioned in a plane substantially parallel to the surface of the receiving interface 51, the locking plate 52 comprising a first through opening 7 disposed vis-à-vis the through opening 6 of the reception interface 51 to be crossed by the connection interface 3 of the relay 1, and at least one second through opening 8, on the one hand, configured to be crossed by a fixing interface 9 of the relay 1 and, on the other part, associated with a cooperation interface 81 with the fixing interface 9 of the relay 1, this cooperation interface 81 being positioned on a portion of the locking plate 52 located on an edge of the second through-opening 8 and opposite opposite the receiving interface 51 ,
- the present system of the invention thus allows a user to operate a positioning of a relay 1 on a reception interface 51 of the circuit breaker 2 in a simplified manner by carrying out an insertion corresponding substantially to a male / female type connection .
- This connection is made jointly at the level of one or more fixing interfaces 9 of the relay 1 so as to anchor the relay 1 to the circuit breaker 2 and at the level of at least one connection interface 3 of the relay 1, so that the relay 1 is able to interact mechanically, electrically and magnetically with the circuit breaker 2.
- These male/female type connections are thus made, on the one hand, between a fixing interface 9 of the relay 1 inserted through a connection interface lock 52, and, on the other hand, a connection interface 3 of the relay 1 inserted through both a locking plate 52 and a receiving interface 51.
- the system of the invention also makes it possible to take advantage of simplified positioning of the relay 1 on the circuit breaker 2 by locking the fixing interface 9 inserted through the receiving interface 51 and the locking plate 52, by translation of the locking plate 52 relative to the reception interface 51 .
- the particular configuration of the second through opening 8 of the locking plate 52 allows, in a first position, the insertion of a fixing interface 9 of the relay 1. In a second translated position, the configuration of the second through opening 8 allows locking of the attachment interface 9 inserted by positioning a part of the locking plate 52 forming the cooperation interface 81 in obstruction on the stroke of displacement of the portion of the fixing interface 9 formed by the abutment 93.
- connection interface 3 of the relay 1 cooperates with a complementary connection interface carried by circuit breaker 2. This assembly participates in the blocking the movement of relay 1 in a plane perpendicular to the axis of insertion of relay 1 .
- the first through-opening 7 of the locking plate 52 has an elongated orifice relative to the orifice of the through-opening 6 of the receiving interface 51.
- This elongated shape of the orifice of the opening 7 is arranged in the direction of the translation of the locking plate 52 so that the through opening 6 of the reception interface 51 is oriented along the axis of movement of the locking plate. lock 52.
- the entire surface of the through-opening 6 of the reception interface 51 fixed and immobile is positioned vis-à-vis d at least part of the first through opening of the movable locking plate 52.
- This arrangement of the first through opening 7 makes it possible to operate an axial translation of the locking plate 52 crossed by the connection interface 3 of the relay 1 without this connection interface 3 limiting the translation of the locking plate 52.
- the circuit breaker 2 is configured so that the locking plate 52 is positioned so as to face the connection interface 3 of the relay 1, between the connection interface 3 of relay 1 and the receiving interface 51 of the circuit breaker.
- the circuit breaker 2 is configured so that the reception interface 51 is positioned so as to face the interface of connection 3 of relay 1, between connection interface 3 of relay 1 and locking plate 52 of the circuit breaker.
- the reception interface 51 of the circuit breaker 2 comprises at least one second through opening configured to be crossed by the fixing interface 9 of the relay 1.
- This second through-opening is then located on the reception interface 51 so as to be, on the one hand, perfectly opposite the second through-opening 8 of the locking plate 52 during the insertion of the fixing interface 9 of the relay 1 and, on the other hand, partially blocked by the cooperation interface 81 of the locking plate 52 when the locking plate 52 is translated into the second position for the blocking of the fixing interface 9 of relay 1 inserted into circuit breaker 2.
- the latter is characterized in that the relay 1 comprises at least two fixing interfaces 9 positioned around the interface of connection 3 to the end of the relay 1 and in that the locking plate 52 comprises at least two second through openings 8 arranged to be crossed by a respective fixing interface 9.
- the locking of the relay 1 on the circuit breaker 2 is operated at the level of at least two anchoring points produced by each of the fixing interfaces 9.
- this multiplication of the number of anchor points allows an optimization of the assembly and the fixing of the relay 1 to the circuit breaker 2.
- the arrangement of the fixing interfaces 9 of the relay 1 between them is then organized to be complementary to the through openings 8 dedicated carried by the locking plate 52.
- the locking plate 52 comprises at least a second through opening 8 of dimension sufficient to be crossed by two fixing interfaces 9 carried by two respective relays 1 positioned juxtaposed on the circuit breaker 2.
- two relays 1 are positioned by insertion on the circuit breaker 2 by being juxtaposed one to side of the other so that at least one fixing interface 9 of each of the relays 1 is close to a fixing interface 9 of the juxtaposed relay 1.
- the juxtaposed relays 1 ensure their positioning so that respective fixing interfaces 9 are also juxtaposed and allow joint interaction with the relay blocking mechanism 1 in the insertion position.
- the locking mechanism which locks these two relays 1 is shared so that the same through-opening 8 has a dimension large enough to be crossed by fixing interfaces 9 of two relays 1 positioned juxtaposed on the circuit breaker 2.
- the juxtaposed attachment interfaces 9 have substantially identical arrangements and arranged to be positioned substantially parallel so that the respective abutment surfaces 93 of the attachment interfaces 9 are arranged to cooperate two juxtaposed portions of the cooperation interface 81 of the locking plate 52 when the latter is translated.
- the cooperation interface 81 with the fixing interface 9 of the relay 1 is carried by at least one spring element 12 mounted on the locking plate 52 and configured to press against the abutment surface 93 and move the abutment surface 93 away from the fixing interface 9 of the relay 1 with respect to the plate locking plate 52.
- a space is likely to exist between the locking plate 52 and the abutment surface 93 of the fixing interface 9 of the relay 1 in maximum insertion.
- a play is then likely to be present between the abutment surface 93 and the locking plate 52 so that the relay 1 inserted and blocked by the locking plate 52 is then likely to struggle axially between, on the one hand, a maximum insertion position and, on the other hand, a bearing position of the abutment surface 93 against the surface of the locking plate 52.
- the spring element 12 is then configured to be positioned between a part of the surface of the locking plate 52 and the abutment surface 93 of the fixing interface 9 of the relay 1.
- the spring element 12 is then configured to exert pressure against the abutment surface 93 in a direction which corresponds substantially to the direction of insertion of the fixing interface 9 of the relay 1 on the circuit breaker 2.
- the spring element 12 is thus configured to exert pressure on the fixing interface 9 which is at least equal to the pressure necessary to operate a displacement of the fixing interface 9 of the relay 1 in maximum insertion.
- the spring element 12 limits, or even eliminates, the travel of the relay 1 in insertion along its translational travel closed by the locking plate 52.
- the play of the fixing interface 9 inserted in the locking plate 52 is is thus suppressed by the spring element 12, so that the locking of the relay 1 on the circuit breaker 2 leads to a stabilization of the relay 1 positioned in insertion on the circuit breaker 2.
- the spring element 12 is produced by at least one curved blade 121 oriented so that the convex face of the curvature is intended to rest against the abutment surface 93, the intersection of the plane of the locking plate 52 and the plane of curvature of the blade 121 corresponding to the axis of translation of the locking plate 52.
- the spring element 12 being mounted on the locking 52, it is moved in translation with the locking plate 52. Also, the spring element 12 is caused to be moved against the abutment surface 93 of the fixing interface 9 of the relay 1 to exert pressure there.
- the curvature of the blade 121 which forms the spring element 12 produces a deformable surface capable of sliding progressively, smoothly, against the abutment surface 93 of the fixing interface 9 of the relay 1 during the translation of the plate locking 52 while being able to exert pressure against this abutment surface 93, once the locking plate 52 has been translated.
- the spring element 12 comprises at least one pair of blades 121 curved parallel to each other and connected at the level of a common end 122, each of these blades 121 being configured to press against the abutment surface 93 of a fixing interface 9 of a respective relay 1.
- the spring element 12 is configured to be positioned at the level of a second orifice 8 of the locking plate 52 crossed by attachment interfaces 9 of two juxtaposed relays 1 and to interact with each of the interfaces of fixing 9 by a respective blade 121 intended to bear against the abutment surfaces 93 of each of the fixing interfaces 9.
- the two blades 121 of the spring 12 are parallel to each other and oriented along an axis corresponding substantially to the axis of translation of the locking plate 52.
- Each of the blades 121 is then able to cooperate with an abutment surface 93 by exerting pressure independently against respective fixing interfaces 9.
- At least one fixing interface 9 of the relay 1 is made under the form of a tab, so that a first part 91 of the tab makes a junction with the rest of the structure of the relay 1 and is arranged along the axis of insertion of the fixing interface 9 through the locking plate 52 and that a second part 92 of the tab carries the abutment surface 93 against the cooperation interface 81 of the locking plate 52, this abutment surface 93 being disposed along a plane perpendicular to the axis d insertion of the attachment interface 9.
- the first 91 and second 92 parts of the leg of the attachment interface 9 are arranged in them so as to form an "L ".
- the tab which forms the fixing interface 9 thus has the shape of a hook whose abutment surface 93 is capable of being blocked in its translation along the axis of insertion of the relay 1 on the circuit breaker 2 by the plate lock 52 and its cooperation interface 81 .
- the relay 1 comprises, at the level of the end of the relay 1 which carries the connection interface 3, a surface 31 intended to be positioned facing a surface of the circuit breaker 2, this surface 31 of the relay 1 comprising at least three non-aligned support points 13 projecting against the surface of the circuit breaker 2.
- Each of these support points 13 projects from the rest of the surface 31 of the relay 1 so as to form a relief.
- the contact of the surface of the circuit breaker 2 is made in a privileged way against the surface 31 at the level of the end of these various points of support 13 projecting.
- the support points 13 of the surface 31 of the relay 1 are thus in contact against the surface of the circuit breaker 2 when the fixing interface or interfaces 9 of the relay 1 are positioned in maximum insertion in the circuit breaker 2.
- the production of a surface 31 comprising three projecting non-aligned support points 13 makes it possible to ensure a stabilized positioning of the surface 31 of the relay 1 against the surface of the circuit breaker 2 within the framework of a maximum insertion of the relay 1 on the circuit breaker 2.
- the surface of the circuit breaker 2 against which the projecting support points 13 are positioned is formed by the face of the locking plate 52 opposite to the face which bears the cooperation interface 81 with the fixing interface 9.
- the circuit breaker 2 comprises an intermediate surface positioned between the locking plate 52 and the bearing surface 31 of the end of the relay 1 .
- This intermediate surface also comprises various openings configured to be crossed respectively by the connection interface 3 and the attachment interfaces 9 of the relay 1 .
- the intermediate surface against which the surface 31 of the end of the relay 1 is configured to bear is produced by the receiving interface 51 of the circuit breaker 2.
- a removable electromagnetic relay 1 such as a coil so that, on the one hand, the connection interface 3 of the relay 1 crosses through openings 6, 7, 8 dedicated to the receiving interface 51 and the locking plate 52 to be in contact with the counterpart connection interface 4 of the circuit breaker 2 and, on the other hand, the at least one fixing interface 9 crosses the at least one second opening through 8 of the locking plate 52,
- the method comprises, together with the locking step, the positioning by insertion of the spring element 12 between the locking plate 52 and the abutment surface 93 of the fixing interface 9 of the relay 1.
