Description

Title of the invention: Assembly comprising electronic protection equipment and a contact module

The present invention relates to the field of electronic protection equipment, such as electronic protection circuit breakers, as well as the field of contact modules.

An electronic protection circuit breaker may for example consist of an open or air circuit breaker, also frequently designated by the acronym ACB (Air Circuit Breaker).

[0003] It is known to optionally add to this type of electronic protection circuit breaker, a contact module which generally comprises one or more contacts. This contact module makes it possible to relay at least one information coming from the electronic protection circuit breaker, for example on a PLC.

[0004] This contact module can, in known manner, be in the form of a sub-assembly forming part of the electronic protection circuit breaker. To install this type of contact module in the electronic protection circuit breaker, it is necessary to disassemble various elements of the electronic protection circuit breaker and to make a certain number of electrical connections. This solution has the disadvantage of making it difficult to add a contact module to the electronic protection circuit breaker.

[0005] Alternatively, the contact module can form a separate entity from the electronic protection circuit breaker, which is located outside the latter, for example on a DIN rail. This solution has the drawback of making the space around which the electronic protection circuit breaker is installed more crowded, for example an electrical distribution cabinet or an electrical panel. This solution also has the drawback of making the electrical connection more complex and of increasing the risk of incorrect connection.

[0006] The publication W02016160307A1 discloses a contact module which is located at the level of the connection block of the electronic protection circuit breaker. This solution also has the drawback of being cumbersome. The present invention aims to overcome at least one of these drawbacks and aims to provide a solution in particular to facilitate the addition or removal of a contact module to electronic protection equipment.

To this end, the invention relates to an assembly comprising at least one electronic protection device and a contact module, said electronic protection device comprising at least:

- at least one current line,

- at least one current sensor able and intended to measure the current flowing in said at least one current line,

- an electronic protection trip unit electrically connected with said current sensor,

- a cut-off device containing at least the electromechanical power subassembly and said at least one current sensor, said electronic protection trip unit being removably mounted relative to said cut-off device, said contact module comprising at least:

- at least one electromechanical relay arranged to relay at least one piece of information from said electronic protection trip device,

- at least first electrical connection means configured to be electrically connected to second electrical connection means that includes the electronic protection trip unit,

- at least third electrical connection means configured to be electrically connected to at least one output connector that said electronic protection device comprises, said contact module being a distinct and separate entity from the electronic protection trip unit, said assembly is characterized in that: said contact module is removably mounted relative to said electronic protection trip device between a mounted position in which said contact module is mechanically and electrically assembled to the electronic protection trip unit and a disassembled position in which said contact module is mechanically and electrically disassembled from said electronic protection trip unit, and in that the contact module and the electronic protection trip unit are arranged so that the passage from the disassembled position to the mounted position of the contact module leads to the electrical and mechanical assembly of the contact module to the electronic protection trip unit and are arranged so that the passage from the mounted position to the dismounted position of the contact module leads to disassembly electric and mechanics from the contact module to the electronic protection trip unit.

The invention relates to a contact module for electronic protection equipment comprising:

- at least third electrical connection means configured to be electrically connected to at least one output connector that said electronic protection device comprises,

[0010] said contact module is characterized in that it is arranged to be removably mounted relative to said electronic protection trip between a mounted position in which said contact module is arranged to be mechanically and electrically assembled to the electronic trip protection and a disassembled position in which said contact module is arranged to be mechanically and electrically disassembled from said electronic protection trip unit. The invention will be better understood, thanks to the description below, which relates to several preferred embodiments, given by way of non-limiting examples, and explained with reference to the accompanying schematic drawings, in which:

[0022] [Fig. 11] FIG. 11 represents a perspective view of the rear of the electronic protection trip unit according to the invention and of the contact module in the disassembled position. As shown in the figures, an assembly comprises at least one electronic protection device 1 and a contact module 2.

[0024] Said electronic protective equipment 1 comprises at least:

[0025] - at least one current line L,

[0026] - at least one current sensor (not shown) able and intended to measure the current flowing in said at least one current line L,

[0027] - an electronic protection trip device 3 (FIGS. 2 to 11) electrically connected with said current sensor,

[0028] - an actuator (not shown) electrically connected with said electronic protection trip unit 3,

[0029] - a cut-off mechanism (not shown), comprising at least one pair of cut-off contacts (not shown) arranged respectively on said at least one current line L and, being able and intended to be actuated by said actuator for open said at least one pair of breaking contacts,

[0030] the actuator and the cut-off mechanism forming an electromechanical power sub-assembly,

[0031] - a cut-off device 4 containing at least the electromechanical power sub-assembly and said at least one current sensor,

[0032] said electronic protection trip unit 3 being removably mounted relative to said cut-off device 4.

[0033] Said contact module 2 (FIGS. 6 and 7) comprises at least:

[0034] - at least one electromechanical relay 18 arranged to relay at least one information from said electronic protection trip unit 3 (Figure 7),

[0035] - at least first electrical connection means 5 configured to be electrically connected to second electrical connection means 6 that includes the electronic protection trip unit 3 (Figures 6 and 7),

[0036] - at least third electrical connection means 7 configured to be electrically connected to at least one output connector 26 included in said electronic protection device 1, [0037] said contact module 2 being a distinct and separate entity from electronic protection trip unit 3.

According to the invention, said assembly is characterized in that:

[0039] said contact module 2 is removably mounted relative to said electronic protection trip unit 3 between a mounted position P01 (FIGS. 4, 8 and 10) in which said contact module 2 is mechanically and electrically assembled to the electronic protection trip unit 3 and a disassembled position P02 (FIGS. 5, 9 and 11) in which said contact module 2 is mechanically and electrically disassembled from said electronic protection trip unit 3,

[0040] and in that the contact module 2 and the electronic protection trip unit 3 are arranged so that the passage from the disassembled position P02 to the mounted position P01 of the contact module 2 causes the electrical and mechanical assembly of the contacts 2 to the electronic protection trip unit 3 and are arranged so that the passage from the mounted position P01 to the disassembled position P02 of the contact module 2 leads to the electrical and mechanical disassembly of the contact module 2 from the electronic protection trip unit 3.

[0041] Advantageously, in this configuration the integration of the contact module 2 in a part of the electronic protection equipment 1 can be done at the time of manufacture of the latter or subsequently in after-sales service. This configuration facilitates the assembly of the contact module 2 relative to the electronic protection device 1 and to propose a contact module 2 which is integrated in a part of the electronic protection device 1, namely the electronic protection trip device 3. The fact of integrating the contact module 2 into the electronic protection trip unit 3 makes it possible to facilitate access to the contact module 2, since the electronic protection trip unit 3 is made easily accessible without having to disassemble parts of the electronic protection equipment 1 with the exception of its front face 13 which is removable from said cut-off device 4. In addition, during the assembly of the contact module 2, that is to say the passage from the disassembled position P02 to the mounted position P01 or disassembly, that is to say the passage from the mounted position P01 to the dismounted position P02, the number of operations is limited. Indeed, during the assembly of the contact module 2, the contact module 2 is simultaneously electrically and mechanically assembled to the electronic protection trip unit 3. When dismantling the contact module 2, the contact module 2 is simultaneously electrically and mechanically disassembled to the electronic protection trip unit 3. Furthermore, the assembly and disassembly of the contact module 2 is done in complete safety at the level of the electrical connection, since it is not necessary to handle electrical cables and to make complex electrical connections.

[0042] Preferably, said contact module 2 is removably mounted relative to said electronic protection trip unit 3 between the mounted position P01 and the disassembled position P02, so as to be accessible if the electronic protection trip unit 3 is assembled to the device cut off 4.

This configuration makes it possible to improve the accessibility of the contact module 2. The contact module 2 can thus be mounted or dismantled even if the electronic protection trip unit 3 is assembled with the cut-off device 4, i.e. that is to say during normal use of the protection device 1, without removing the electronic protection trip unit 3. Indeed, thanks to this arrangement, one avoids having to disassemble the electronic protection trip unit 3 from the device of cut-off 4 and to disconnect it electrically when mounting the contact module 2 on the electronic protection trip unit 3.

[0044] If the electronic protection device 1 further comprises a front face 13 which is removable from the switching device 4, then the contact module 2 is removably mounted relative to said electronic protection trip device 3 to be further accessible when the front face 13 is removed from the cut-off device 4.

Preferably, in the mounted position P01, said first electrical connection means 5 are electrically connected to said second electrical connection means 6.

[0046] Preferably, in the mounted position P01, the first electrical connection means 5 and the second electrical connection means 6 preferably face each other. Preferably, in the disassembled position P02, said first electrical connection means 5 are electrically disconnected from said second electrical connection means 6.

Preferably, said first electrical connection means 5 and said second electrical connection means 6 are chosen from electrical connectors of the “plug and play” or zero insertion force type or spring-loaded connectors.

[0050] Preferably and as shown in Figures 2 to 11, said electronic protection trip unit 3 comprises a first housing 8 comprising a first accessible face f1 called front comprising at least one man-machine interface, a second accessible face f2 called lateral which is orthogonal to the first face f1 and with respect to which said contact module

2 is removably mounted and a third so-called mounting face f3 which is opposite to the first face f1 and is arranged to be assembled with the cut-off device 4 and be inaccessible when the electronic protection trip unit

3 is assembled to the breaking device 4.

The term "accessible" face of the electronic protection trip unit 3 is understood to mean a face to which the user has access without dismantling the electronic protection trip unit 3 of the cut-off device 4 of the electronic protection equipment 1, c' is the case for example of the first face f1.

The term "accessible" side of the electronic protection trip unit 3 also means a side to which the user has access without disassembling the electronic protection trip unit 3 from the electronic protection device 1 and by removing only the front face 13 of the electronic protection device 1, this is the case for example of the second face f2.

The term “inaccessible” side of the electronic protection trip unit 3 is understood to mean a side to which the user does not have access without dismantling the electronic protection trip unit 3 of the cut-off device 4 of the electronic protection equipment 1 , this is the case for example of the third face f3.

Advantageously, this configuration allows access to the contact module 2 laterally via the second face f2 of the electronic protection trip unit 3. This results in an improvement in the accessibility of the contact module 2. Indeed, to access the contact module 2 or mount it, simply remove the front panel 13.

Preferably, said first linear guide means 11 and second linear guide means 12 extend straight and parallel to the direction of insertion D.

[0065] Advantageously, the reception area 10 makes it possible to contain in whole or in part the second housing 9 of the contact module 2. The contact module 2 is thus housed in whole or in part in a part of the electronic protection trip unit 3 This results in a particularly compact layout.

[0066] Preferably, said reception zone 10 opens out at least on the second face f2 of the first box 8.

[0067] Preferably, the first housing 8 comprises at the level of the second so-called lateral face f2 an opening 14 giving access to the reception zone 10 and allowing the insertion of the contact module 2 into the reception zone 10 and into the insertion direction D.

[0069] Preferably and as shown in Figure 11, the first housing 8 comprises at the level of the third so-called mounting face f3 an opening 15 giving access to the reception area 10 but not allowing the insertion of the module of contacts 2.

When the contact module 2 is not mounted on the electronic protection trip unit 3, it can be replaced by an empty casing (not shown) which has the same dimensions as those of the second casing 9 which makes it possible to fill the reception area 10 and above all to protect said second electrical connection means 6.

This first connection rail is usually mounted on the upper part of the cut-off device 4 and is arranged at the rear of the front face 13.

To facilitate the signal recovery operation, the electronic protection device 1 can also comprise a second connection rail 27 provided with a plurality connectors which are each electrically connected to a connector of the first connection rail.
