Description

Title: ELECTRICAL CONNECTION ASSEMBLY FOR ELECTRICALLY CONNECTING TWO SLIDING ELEMENTS RELATIVE TO THE OTHER.

Technical area

The present invention relates to the field of electrical connection assemblies. The invention aims more particularly to provide an electrical connection assembly configured to electrically connect two elements movable relative to each other, and more particularly two sliding elements relative to each other.

This is, for example, a connection assembly for connecting an opening to a frame or to another opening so as to transmit information via a communication bus.

It can also be a connection assembly for connecting an opening fitted with glazing that can be activated by electric current, to a frame or to another opening. The openings can be part of a room such as a veranda, part of a building with glass walls or a public swimming pool.

By "glazing activated by electric current" is meant a glazing of which one or more physical characteristics can be modified by application of an electric current. This is, for example, heated glazing or even variable blackout glazing.

By "heated glazing" is meant a glazing comprising at least one sheet of glass coated with one or more thin layers capable of producing heat by application of an electric current.

By "variable blackout glazing" is meant a glazing comprising at least one sheet of glass and the degree of opacity of which can be controlled by the application of an electric current. This includes in particular electrochromic glazing and glazing in which at least one glass sheet is coated with at least one liquid crystal film.

Prior art

It is known to use glazing that can be activated by electric current to regulate the brightness of a room. Such a variable occultation glazing can in particular be a so-called electrochromic glazing or a glazing with liquid crystal film (s).

An electrochromic glazing usually comprises an assembly of stacked layers capable of exchanging electrical charges. The degree of opacity of the layers can be controlled by a transfer of electric charges between the different layers, this transfer being generated by the application of an electric field.

Another type of variable occultation glazing consists of a glazing comprising at least one liquid crystal film, generally in the form of liquid crystal droplets arranged in a polymer matrix. The opacity of such a film depends on the orientation of the liquid crystal, which is also controlled by the application or non-application of an electric field.

It is also known to use glazing that can be activated by electric current to produce heat.

Such heated glazing can be double glazing or triple glazing.

In the case of double glazing, the interior pane, that is to say the sheet of glass which is in contact with the air inside the building, is coated with at least one thin heating layer on its exterior surface. , ie the surface facing the outside of the building. The thin heating layer, generally made up of metallic microparticles deposited on the surface of the glass, is connected to an electrical supply. Under the effect of an electric current, the heating layer reaches a temperature typically between 20 ° C and 45 ° C and produces thermal radiation. The inner pane is usually made of tempered glass.

The outer pane has on its inner surface, that is to say the one facing the inner pane, a thin reflective layer suitable for reflecting the thermal radiation produced by the heating layer.

The space between the two panes can be filled with an inert gas.

In the case of triple glazing, a third pane is arranged between the inner pane and the outer pane, in order to improve thermal insulation.

In terms of comfort, heated glazing constitutes a gentle and homogeneous source of heat. As it is radiant heating, it provides a feeling of homogeneous heat while avoiding the phenomena of air convection generated by convection heaters. It thus limits the drafts, the movement of dust and the drying out of the air associated with this type of heating.

It advantageously makes it possible to avoid the cold wall effect of a glazing when the outside temperature is lower than the building temperature and to avoid condensation phenomena on the surfaces in contact both with the inside air and 'outside. In addition, a heated glazing system saves space by eliminating the need to install additional heaters, for example on the walls of a room.

Heating by heated glazing is particularly advantageous in the context of heating rooms or buildings with many glazed surfaces, such as verandas, swimming pools, spas, sports halls, certain roofs or even buildings with large glazed surfaces. .

Heated glazing prevents heat dissipation from a heated location through windows or other glass surfaces; it can also perform anti-condensation or snow removal functions.

However, in the case of mobile heated glazing (eg sliding glass doors), the installation and implementation of a heated glazing solution remains a relatively complicated and expensive operation.

Indeed, it is necessary to ensure an electrical connection between the opening comprising the glazing, movable, and the corresponding fixed frame.

The application EP 2451038 A1 concerns the protection of electric cables between the frame and the opening of a door or a window, which is pivotally mounted on the frame. It is known to provide an electrical connection between two elements in relative sliding to implement devices of the cable carrier type, in which the electric cables and / or the control cables are inserted in a chain which ensures the guiding of the cables. . The chain is configured to deform according to the relative position of the sash and the frame, typically along two parallel axes following a guide rail.

However, the existing solutions are not entirely satisfactory.

Each installation of heated glazing is in fact a special case: it is therefore necessary to customize the electrical connection devices for each installation. In other words, there are currently no standardized solutions that would allow access to a volume market.

In addition, the existing solutions turn out to be relatively complex both in terms of design and installation. The lifetime of known solutions may also not be sufficient in the context of the main application targeted. An installation of heated glazing is in fact likely to be used for several decades.

To ensure the electrical connection between the opening and frame of a glazing, a solution that could be considered is the implementation of magnetic connections, which are for example described in patents FR 3038460 B1 and FR 3038781 B1. However, the solutions described. are not entirely satisfactory. Indeed, they are based on the use of mechanical means with a return spring to return the male contacts to their retracted position inside a housing when the male and female parts are not connected. Ultimately, the reliability of these mechanical means may deteriorate, which may cause unwanted retention of the male contacts in their deployed position outside the housing and therefore generate a safety risk.

In addition, the simultaneous connection of the contacts generates a risk of cutting the alternating electric current outside zero.

There is therefore a need for an electrical connection assembly solution for connecting two sliding elements relative to each other which overcomes the drawbacks of the aforementioned solutions.

The aim of the invention is to at least partially meet this need.

Disclosure of the invention

To do this, the invention relates to an electrical connection assembly, intended to electrically connect two sliding elements relative to each other, comprising:

a male connector mounted on a first element, comprising at least three male contacts, including at least one earth contact, at least one power contact, and a closed position contact between the two elements;

- a female connector mounted on a second element, comprising at least three female contacts complementary in number and position to the male contacts, the assembly being configured so that, when sliding to separate the second element from the first element, the male contact of closed position is disconnected from its female contact before disconnection of the earth and power contacts, and F at least one male earth contact is disconnected from its female contact after disconnection of the power contacts and the closed position contact, and vice versa during sliding to bring the second element closer to the first element. Thus, the invention essentially consists of a connection assembly in two parts, each mounted on one of two elements sliding relative to one another. The electrical connection is made by the contacts of each of the male and female connectors when the connectors are in the connected configuration.

Thanks to the invention, the use of cables to provide the electrical connection between the two sliding elements is avoided.

Advantageously, and unlike existing solutions, the connection assembly according to the invention can be installed in any structure without requiring customization according to the characteristics thereof: it is a universal solution. .

However, a connection assembly according to the invention does not provide any electrical connection in the disconnected position: this may for example be the case when an opening comprising a glazing which can be activated by electric current is opened by a user. Advantageously, in the case where the connection assembly makes it possible to supply power to a heated glazing, this makes it possible to automatically cut off the heating when a door or window is opened. But it is then important on the one hand to allow continuity of the earth line until the connection is completely cut off, and on the other hand to ensure that the power lines are cut only after switching on. at zero of the voltage on these lines.

In fact, it could be detrimental for the power lines to be cut without the voltage being set to zero, in particular in the case of blackout glazing comprising liquid crystals.

To guarantee these functions, the contacts of the male and female connectors are configured to disconnect at different times from the connection and disconnection movements. Thus, the ground contact is the first contact to be connected and the last contact to be disconnected: the ground line is therefore the first of the lines of the connection assembly to be connected during a connection of the assembly, and the last to be disconnected during a disconnection. This ensures the continuity of the earth line until complete disconnection.

Conversely, the closed position contact is the last contact to be connected during a connection of the connection assembly, and the first contact to be disconnected during a disconnection. The closed position contact is therefore configured to allow the detection of a disconnection of the assembly before the power contacts are disconnected.

The detection of the disconnection of the assembly can be carried out by an electronic circuit external to the connection assembly, or else by an electronic circuit integrated into the connection assembly.

Thus, thanks to the information provided by the closed position contact, it is possible to zero the voltage on the power lines before the power contacts are disconnected. Conversely, during a connection, it is possible to prevent any passage of electric current through the power contacts as long as the closed position contact is not connected.

It is then possible to avoid cutting power lines at a non-zero voltage. According to an advantageous embodiment, the male contacts are cylindrical pins, the female contacts being cylindrical sleeves complementary to the pins.

The contacts can however take other forms, such as contact blades or other known form.

According to an advantageous characteristic, the male connector comprises at least five male contacts and the female connector comprising at least five female contacts, the male connector comprising at least three power contacts of the same length, two of which are configured to supply electric power to the first or the first. second element, and the other is configured to electrically power a probe or a device attached to the first or the second element.

This feature advantageously makes it possible to supply a probe or a device arranged on the mobile element. It may for example be a temperature sensor arranged on a heated glazing and configured to determine the surface temperature of the glazing. Preferably, each of the male and female connectors comprises at least four power contacts, one of which is configured to serve as a voltage reference, typically at 0 V. Advantageously, each of the male and female connectors is supported by a support, one of the supports. being mounted with play on a housing, so as to compensate for a misalignment between male and female connectors in at least one direction.

According to an advantageous embodiment, each of the male and female connectors comprises at least one transmission contact configured to transmit information carried by an electric current, the assembly being configured so that, when sliding to separate the second element of the first element, the closed position male contact is disconnected from its female contact before disconnection of the transmission contact, and at least one male ground contact is disconnected from its female contact after disconnection of the contact from transmission, and vice versa during sliding to bring the second element closer to the first element.

This mode makes it possible to transmit information originating for example from a device arranged on the first or on the second element (such as an anti-burglary alarm device) or even from a device arranged outside a building comprising the connection set.

Preferably, the support is mounted on the housing with play in the three spatial directions. Thanks to this feature, it is possible to compensate for alignment clearances between the two elements, for example between a frame and a window sash.

More preferably, the housing comprises a main body provided with a groove and a cover for closing the housing when arranged on the main body, the closure cover being provided with a stop, the support mounted with clearance on the housing comprising at least one pin inserted into the groove and held therein by the stopper with play in at least one direction, preferably in three spatial directions.

According to a particular embodiment, one of the male or female parts comprises at least one centering pin configured to cooperate with an opening in the other of the male or female parts so as to provide guidance between the male and female parts during sliding.

According to an advantageous variant, each of the male contacts is surrounded by a first envelope of length greater than that of the male contacts and each of the female contacts is surrounded by a second envelope of length greater than that of the female contacts, the first and second envelopes being configured. to cooperate so as to provide guidance between the male and female parts during sliding.

Such guidance, more precise between male and female parts, makes it possible to limit the friction of the male and female contacts during connection and thus allows better resistance to the connection and disconnection cycles.

Preferably, the male and female contacts are coated with a layer of gold and then lubricated. This makes it possible to further reduce friction and thereby improve the service life of the male and female contacts. According to another of its aspects, the invention relates to the use of a connection assembly according to the invention for providing an electrical connection / disconnection between an opening fitted with a glazing, in particular a functional external glazing with probe, and the frame. a room, such as a veranda or between two openings equipped with glazing of a room, such as a veranda.

There is illustrated in Figure 1, a system 1 comprising a fixed window frame 2, an opening 3 movable in translation relative to the frame 2 and an electrical connection assembly 10 according to the invention.

In the configuration shown in Figure 1, the frame 2 and the sash 3 are in the closed position and the connection assembly 10 is in the connected position.

In the configuration shown in Figure 2, the frame 2 and the sash 3 are in the open position and the connection assembly 10, which comprises a female part 11 and a male part 12, is in the disconnected position. The female part 11 is in fact completely disconnected from the male part 12.

Figures 3 to 6 schematically show an embodiment of the connection assembly 10 at different stages of a method of connecting the assembly.

As can be seen in these figures, the male part 12 comprises, in the example illustrated, a male connector with six male contacts 13 to 18 in the form of cylindrical pins. The female connector 11 comprises a female connector with six female contacts 19 to 24 in the form of sockets, complementary in number and in position to the male contacts.

The male contact 13 of greater length is a ground contact.

The contacts 14 and 15, of intermediate length with respect to the other contacts, are power contacts configured to transmit an electric current.

The contact 16, of the same length as the power contacts 14 and 15, is a contact configured to supply electrically a probe or a device connected to the connection assembly, such as for example a temperature probe measuring the surface temperature of a heated glazing, and to transmit the measurements taken by the probe or the device.

Contact 17, also of identical length to power contacts 14 and 15, is configured to serve as a voltage reference, typically at 0 V.

Contact 18, of shorter length than that of the other contacts, is a closed position contact. This contact advantageously makes it possible to detect the opening or closing of the connection assembly, that is to say the disconnection or the connection of the male and female connectors respectively.

Indeed, as its length is shorter than that of the other contacts, it is the first contact to be disconnected during a disconnection movement of the male connectors and female. Thus, the connection assembly 10 is configured so that, as soon as the contact 18 is disconnected, no electric current flows through the power contacts.

Likewise, during a connection movement of the male and female connectors, the connection assembly 10 is configured so that no electric current passes through the power contacts before the contact 18 is connected to the corresponding female contact 24. . As shown in Figure 3, connection assembly 10 is in a fully disconnected configuration. Indeed, no male contact is connected to a corresponding female contact.

In Figure 4, the ground contact 13 is connected to the corresponding female contact 19, but none of the other contacts are connected.

In figure 5, the ground contact 13 as well as the intermediate length contacts 14, 15, 16, 17 are connected to the corresponding female contacts 19 to 23, but the closed position contact 18 is not connected to the female contact 24 corresponding.

In this position, any electric current can be prevented from flowing in particular the power contacts 14, 15, because the closed position contact 18 is not connected: this information allows an electronic control circuit to prevent circulation. of a current in the power contacts 14, 15.

In Figure 6, the full connection of the connectors of the male 12 and female 11 parts is achieved. Since the closed position contact 18 is connected to the contact 24, the connection assembly 10 is configured so that an electric current can flow through the other contacts 13 through 17.

Figure 7 shows another embodiment of a connection assembly 10 according to the invention.

In this example, the female part 11 comprises a housing 25 consisting of a main body 26 and a closing cover 27. The housing 25 houses a support 28. The support 28 is configured to support the female connector 50, which is in this embodiment consisting of two sub-assemblies 29, 40. The sub-assembly 40 of the female connector 50 comprises a male ground contact 37 and a female ground contact 19. The sub-assembly 29 houses the power contacts, transmission and closed position within the envelopes 54, as more particularly visible in Figure 10.

The support 28 further comprises centering pins 30 and a centering pin receptacle 32. Advantageously, the support 28 is mounted with play on the housing 25.

The male part 12 comprises a housing 33 housing a male connector 51. The male connector 51 is, in the illustrated embodiment, made up of two sub-assemblies 34, 35. The sub-assembly 35 houses the male power and power contacts. closed position in the envelopes 55. The sub-assembly 34 comprises a male ground contact 13 configured to cooperate with the female ground contact 19 of the female connector 50 as well as a female ground contact 31 configured to receive the ground contact male 37 of female connector 50.

The housing 33 has openings 36 configured to receive the centering pins 30, during the connection between male and female parts.

Thus, when the male and female parts are brought together, the centering pins 30 cooperate with the openings 36 to allow a first guidance between the male and female parts. Secondly, the ground contacts 13, 31, 19, 37 ensure more precise guidance of the connection of the male and female parts.

Finally, the envelopes 54, 55 respectively surrounding the male contacts and the female contacts lead to an even more precise alignment of the male and female contacts, which minimizes friction during connection.

This guide mechanism advantageously makes it possible to significantly reduce the wear of the male and female contacts, in order to guarantee a long life for the connection assembly.

Figure 8 is a view of the elements shown in Figure 7 from a different viewing angle. Figure 9 is an exploded view of the male 12 and female 11 parts of the connection assembly 10.

In the illustrated embodiment, the female connector 50 consists of two subassemblies 29, 40 integral with one another. The female connector 50 could also consist of a single part. Likewise, the male connector 51 here consists of two sub-assemblies 34, 35 integral with one another, but it could also consist of a single part.

FIG. 10 is a side view of the sub-assembly 35 housing the male power contacts 14, 15, 16, 17 and a transmission 52 and closed position contact 18, the male contacts being shown disconnected from the sub-assembly 35. As can be seen clearly in this figure, the male connector has four power contacts and one power contact. transmission in this embodiment. The transmission contact 52 makes it possible to transmit information carried by an electric current.

FIG. 11 is a view of the sub-assembly 29 as well as of the ground contacts 19, 37 of the female part and of the ground contacts 13, 31 of the male part.

Figure 12 shows all of the contacts 13, 14, 15, 16, 17, 18, 31, 52 of the male part and the contacts 19, 20, 21, 22, 23, 24, 37, 53 of the female part of a connection assembly according to the invention, the contacts being shown outside the sub-assemblies 29, 35 which house them.

The alignment of the male contacts in Figure 12 is representative of the connection order of the various contacts during a connection of the male and female parts. Indeed, as visible in Figure 12, the ground contacts 13, 31 are positioned so that their ends come into contact with the ground contacts 19, 37 of the corresponding female part before the other male contacts enter. in contact with the corresponding female contacts. The power and transmission contacts 14, 15, 16, 17, 52 are aligned with each other and are positioned so as to come into contact with the corresponding female power contacts 20, 21, 22, 23 and transmission 53 after the contacts earth, but before the closed position contact 18 comes into contact with its corresponding female contact 24.

As can be seen in FIG. 13, the female part 11 is configured so that the support 28 is mounted with play on the housing 25.

Indeed, the centering pins 30 extend on both sides of the support 28. The parts 41 of the centering pins 30 extending inwardly of the housing 25 comprise an insertion section 42 and a stop section 43 of diameter greater than that of the insertion section 42. The insertion sections 42 are intended to be inserted into grooves

44 of the housing 25. The stop sections 43 are configured to have a diameter greater than the dimensions of the grooves 44 so as to prevent disinsertion of the support 28 from the housing 25 along an axis X of connection between the male 12 and female 11 parts. As can be seen in FIG. 14, the closing cover 27 advantageously acts as a stopper.

45 when mounted on the main body 26. The stops 45 in cooperation with the grooves 44 make it possible to maintain the centering pins 30 in the grooves 44 in two directions Y and Z orthogonal to each other and both orthogonal to the direction X of connection between the male 12 and female 11 parts. Thus, the centering pins 30, the grooves 44 and the stops 45 are configured so as to maintain the pins 30 in the grooves 44 with play.

The clearances jx, jy, jz along the three axes X, Y, Z are shown in figures 14 and 15.

Preferably, the clearances jx, jy, jz of the pegs 30 in the grooves 44 are such that jx £ 2 mm; jy <2 mm; jz £ 4 mm, and are even more preferably such that jx £ 1 mm; jy <1 mm; jz £ 2 mm.

The invention is not limited to the examples which have just been described; characteristics of the examples illustrated can in particular be combined with one another within variants not illustrated. Other variations and improvements can be envisioned without departing from the scope of the invention.

For example, if in the illustrated embodiments, each element of the connection assembly has a number of seven contacts on the male connector 13 to 18 and 31 or eight contacts on the male connector 13 to 18, 31 and 52, we One can consider an element with three contacts in all on the male connector, including a ground contact, a power contact and a contact for the closed position.
