    Electrical connection device, method of assembling a female part of this connection device, super-insulation mattress and spacecraft
    The present invention is in the field of spacecraft and in particular in artificial satellites. In these machines, all objects must be grounded to prevent electrostatic discharge. This grounding is usually done by connecting to a satellite structure panel.
    The present invention relates to an electrical connection device for connecting a super-insulation mattress to a structural panel of a spacecraft, a super-insulation mattress and a spacecraft.
    Super-insulating mats generally called MLI (Multi-Layer Insulation) are, for example, used to thermally insulate a set of equipment operating over a temperature range of another set of equipment operating on a other temperature range. These super-insulation mats are also used to thermally insulate a spacecraft panel against the effects of solar heating and space-side radiation heat loss. These super-insulating mattresses are composed of a sheet or a stack of several thermally insulating sheets and electrically conductive and possibly electrically nonconductive mesh interposed between the electrically conductive sheets. These lattices are used to promote the thermal insulation by separation of the elements. This stack of sheets and possibly lattices has a thickness less than one millimeter. Traditionally, to put the super insulation mattress to the ground, the sheets are perforated and then fixed together using a rivet or a set screw-nut. In order to ensure a good electrical contact between, on the one hand, this rivet or the screw-nut assembly and, on the other hand, all the electrically conductive layers, a conductive material is interposed between these layers, such as, for example, metal washers. An electrical cable is assembled to the rivet simultaneously or later and attached to an insert embedded in the satellite structure panel.
    However, this arrangement has many disadvantages. Indeed, during the realization of the satellite, it may be necessary to remove a super-insulating mattress, for example to replace equipment that did not give satisfaction during the tests, to perform an additional check under the super insulation mattresses or to add new equipment or a new function requested by the customer. In these cases, the electrical cable that connects the insert to the super-insulation mattress must be disconnected. This disconnection is delicate because the sheets of the super insulation mattress are very fragile. They tear easily or deteriorate so that the super insulation mattress does not really provide its insulation function.
    In addition, often a dozen electrical cables are attached to each insert so that when reconnecting the electrical cables to the insert, the operator can forget to reconnect a cable. To avoid such an oversight, all electrical connections are tested after the final assembly of one or more super insulation mattresses. This operation is long and delicate.
    Finally, the positioning of the inserts relative to the structural panels of the spacecraft, must be determined very early, during the design, because, because of their small thickness, the structural panels can not be perforated. They must be designed with the inlet openings of the inserts. However, as the duration of construction of a satellite is increasingly shorter and the specifications of customers evolves over time, it is difficult to predict the positioning of the inserts in advance. To overcome this disadvantage, longer electrical cables can be used to connect the panel insert to the rivet of the mattress. Nevertheless, these electric cables are expensive and weigh down the satellite. In addition, these cables pass under the neighboring mattresses, which makes their installation complicated.
    The object of the present invention is to provide an electrical connection device which is easily connectable and disconnectable without risk of tearing or deterioration of the super insulation mattress, and without depending on the presence or absence of adjacent mattresses and preinstalled electrical cables. To this end, the subject of the present invention is an electrical connection device intended to connect a super-insulating mat to a structure panel of a spacecraft, said connection device comprising: a conductive sleeve having an axis extending according to a first direction, said sleeve comprising an axial fixing device of the insulating mat and a support extending in the first direction, - a conductive pin capable of being arranged in said sleeve, - an elastic member carried by said support, said elastic member being able to exert on the pion a force in a direction substantially perpendicular to the first direction to press the pin against the sleeve.

    Advantageously, the sleeve can slide along the pin. This possibility of movement allows a vertical play of the mattress with respect to a structural panel of the spacecraft. This vertical game facilitates the assembly and disassembly of a mattress with respect to this structural panel. The elastic element and the difference in length between the pin and the sleeve ensure permanent electrical contact between the sleeve and the pin while permitting axial movement of the pin relative to the sleeve, during installation or during handling of the pin. mattress.

The elastic member comprises a central rod segment, two intermediate rod segments, each bent with respect to the central rod segment, and two end rod segments, each bent with respect to an intermediate rod segment, and wherein the angles between the rod segments are obtuse angles, said angles being substantially identical, when the elastic member is not constrained. The end shank segments are adapted to exert on the carrier a force having a substantially radial direction and wherein the length of the end shank segments is greater than the length of the intermediate shank segments. - The axial fastening device comprises a peripheral collar to the sleeve extending in a plane perpendicular to the first direction and wherein the support comprises two planar faces extending in the same plane, said plane being substantially perpendicular to the plane of the collar , said planar faces being bearing faces of the elastic element, when the conductive pin is clear of said sleeve.
    Advantageously, the central segment of the elastic element is supported on the flat faces of the support, when the pin is not arranged in the sleeve. The length of the central rod segment is substantially greater than the length defined between the ends of the flat faces of the support, and wherein the angle between the central rod segment and the intermediate rod segment is substantially identical to the angle defined between the flat faces of the support and the outer face of the support.

    In particular, the step of establishing a stop comprises a step during which the free end of the sleeve is flared.
    In particular, the step of establishing a stop comprises a step of clamping the free end of the sleeve.
    Advantageously, the electrical connection between the conductive sheets and the sleeve is provided solely by the flange, the washer and the outer surface of the sleeve. The pressure exerted in a calibrated manner makes it possible to ensure that the residual pressure exerted on the super-insulating mat is sufficient and reproducible, thereby guaranteeing the continuity of the electrical connection, without having to insert electrically conductive elements.

The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the figures in which: FIG. 1 is a perspective view of a connection device according to FIG. present invention; FIG. 2 is an exploded perspective view of the connection device illustrated in FIG. 1; - Figure 3 is a sectional view along the plane III-III of the connection device illustrated in Figure 1; FIG. 4 is a sectional view of a structural panel and a super-insulating mat fixed to the panel by the connection device illustrated in FIG. 1 and a stop, the sectional plane being perpendicular to the plane of the super insulation mattress; and - Figure 5 is a front view of a stop.
    The present invention is defined with respect to an orthogonal coordinate system R (x, y, z) shown in FIG. 1. By convention, in the description which follows, the direction z of the reference R (x, y, z) is called "First direction", the x direction of this landmark is called "second direction" and the y direction of this landmark is called "third direction". In the description which follows, the terms "high", "low", "lower", "higher" are defined when the connection device according to the invention is arranged as illustrated in FIG. 1, and are in no way limiting. .
    The present invention relates to a connection device 2 adapted to electrically connect the sheets 4 constituting one or more super-insulating mattresses 6 to a structure panel 8. In the following description, it will be considered that the connection device 2 is attached to a single mattress 6. This arrangement is intended to facilitate understanding of the invention. It is not limiting.
    With reference to FIGS. 1, 2 and 4, the connection device 2 according to the invention comprises a washer 10, a conductive sleeve 12, a conducting pin 14 capable of being introduced and removed from the sleeve 12 during connection and during the disconnecting the super insulation mattress 6 to the structure panel 8, and an elastic member 16 adapted to push the pin 14 against the sleeve 12 to press against the sleeve and ensure electrical contact therebetween.
    Preferably, the washer 10 is reversible.
    With reference to FIG. 2, the sleeve 12 comprises, from bottom to top, a free end 18 and an end 20 provided with a peripheral collar 22 and a support 24 placed above the collar 22.
    The sleeve 12 has an axis A-A which extends in the first direction z. The flange 22 is disposed in a plane (x, y) perpendicular to the first direction z.
    As shown in Figure 4, the sleeve 12 is intended to be introduced into through holes 26 formed in the sheets 4 of the mattress. These sheets 4 are thermally insulating and electrically conductive. They will be called conductive sheets 4 below. When the connection device 2 is fixed to the mattress 6, the conductive sheets 4 of the super-insulation mat are interposed between the washer 10 and the flange 22. The free end 18 of the sleeve is intended to form or receive a locking / crushing device mattress. The collar 22, the washer 10 and the free end 18 of the sleeve form an axial fixing device of the conductive sheets of the super-insulating mattress.
    According to the preferred embodiment, the axis A-A of the sleeve 12 has a central symmetry and has a circular shape. However, according to other non-limiting embodiments, other forms are possible for the sleeve 12, such as a square shape.
    The support 24 extends in the first direction z. It has the shape of a truncated crown which extends in the plane (x, y) on an angular sector between 40 ° and 320 °. This ring has an axis substantially coincident with the axis A-A of the sleeve 12.
    The cutting plane (x, z) of the truncated crown extends substantially perpendicular to the plane in which the flange 22 is contained. It is disposed at a distance d defined so as to generate two section planes and a passage opening 32 of the pin disposed between the two section planes. The two section planes form flat faces 28, 30 of support of the elastic element. These two planar faces 28, 30 extend in the same plane which is the plane of section.
    The distance d is the maximum distance between a point on the inner face 34 of the sleeve and its orthogonal projection on the plane of section (x, z). This distance d is smaller than the diameter of the pin 14.
    When the pin 14 is not arranged in the sleeve 12, the elastic element 16 bears against the flat faces 28, 30 of the support. When the pin 14 is arranged in the sleeve 12, a portion of the pin protrudes outside the support 24, through the passage opening 32. The elastic member 16 is then supported on the pin 14 and exerts on it a force substantially perpendicular to the axis of the sleeve 12.
    The outer face 36 of the support is provided with a bead 38 in an arc. This bead 38 defines with the collar 22 a groove 40 for receiving the elastic element 16. This groove 40 extends over a circular arc.
    The conductive pin 14 comprises a head 42 and a foot 44.
    The head 42 is preferably flat and smooth. It is suitable for being bonded to the structure panel 8, using an electrically conductive adhesive.
    Advantageously, this electrically conductive bonding can be performed later in the realization of the satellite because the location of the bonding does not need to be defined at the time of the design of the satellite structure panels. In addition, in case of bad positioning of the pawn, another pawn can easily be glued to another location.
    The foot 44 has a length of between 1 and 2.5 times the length of the sleeve 12 in the first z direction so that the sleeve can slide axially relative to the pin to allow a slight displacement of the super insulation mat 6 relative to the structural panel 8.
    The foot 44 comprises from bottom to top, a first chamfer 46, a circular groove 48 and a second chamfer 50.
    The first 46 and second 50 input chamfers facilitate the insertion of the pin 14 into the sleeve 12, when the elastic member 16 is mounted on the support.
    Advantageously, the circular groove 48 is adapted to receive a stop 52 for stopping the sleeve.
    This stopper is removable. It is adapted to block an involuntary output of the pin 14 relative to the sleeve 12. The thickness of the stopper must be adapted to ensure that there will always be at least one contact between the elastic element and the pin, including taking into account the reversibility of the sleeve 12. Thus, the thickness of the stop must be sufficient to maintain the spring below the low limit of the second input chamfer 50. By way of non-limiting example, the abutment stop includes a disc 53 having a radial slot 55.
    Preferably, the stop stop is reversible. The elastic element 16 is, for example, constituted by a rod. This rod is made of metal and preferably steel. It has, for example, a diameter less than one millimeter.
    According to the embodiment shown in the figures, this rod 16 is folded in the form of an open pentagon.
    Thus, in the embodiment of the invention shown, the resilient member 16 includes a central shank segment 54, two intermediate shank segments 56, each angled with respect to the central shank segment 54, and two shank segments. end 58, each bent with respect to the intermediate rod segment 56 adjacent thereto.
    The central rod segment 54 is able to exert a force substantially perpendicular to the first direction z to press the pin 14 against the sleeve 12.
    The end rod segments 58 are adapted to exert on the support 24 a force having a substantially radial direction when the pin 14 is arranged in the sleeve 12. For this purpose, the length of the end rod segments 58 is preferably greater than the length of the intermediate rod segments 56.
    The shape and the material of the elastic element 16 as well as the dimensions of the pin 14 and the sleeve 12 are chosen so that the stress exerted by the pin 14 on the elastic element 16 is less than the elastic limit. of the elastic element so as to ensure a reliable and durable electrical contact between the sleeve 12, the pin 14 and the elastic element 16.
    Advantageously, the joint forms of the elastic element 16 and the support 24 create four simultaneous and permanent mechanical and electrical contacts: two electrical contacts between the elastic element 16 and the support 24, a contact between the elastic element 16 and the pin 14 and a contact between the pin 14 and the sleeve 12.
    In the embodiment shown and in no way limiting, the elastic element is fitted around the support 24. Thus, the length of the central rod segment 54 is substantially greater than the length defined between the ends of the flat faces 28, 30 of the and the angle α between the central rod segment 54 and the intermediate rod segment 56 is substantially identical to the angle β defined between the flat faces 28, 30 of the support and the outer face 36 of the support.
    In the embodiment shown, the angles defined between the rod segments 54, 56, 58 are obtuse angles. These angles a are substantially identical when the elastic element 16 is not constrained.
    Alternatively, the elastic member is constituted by a flat tab.
    Alternatively, the elastic member has the form of an n-sided polygon with n between 2 and 10.
    As a variant, the elastic element has the shape of a U or an open or closed circle.
    Alternatively, the end of the foot is rounded.
    Alternatively, the axial attachment device may be replaced by a screw thread made at the free end of the sleeve and by the use of a nut.
    Alternatively, the support comprises at least one flat or curved wall on which the elastic element is attached to push the pin against the inner wall of the sleeve.
    According to a variant not shown, the joint forms of the elastic element and the support generate at least three simultaneous and permanent mechanical and electrical contacts: at least one electrical contact between the elastic element 16 and the support 24, at least one contact between the elastic element 16 and the pin 14 and at least one contact between the pin 14 and the sleeve 12. Depending on the shape of the elastic element and its positioning on the sleeve 12, additional contacts are possible, beyond these three minimal contacts.
    Moreover, to ensure electrical contact between the electrically conductive sheets and the non-conductive lattices of the super-insulating mat, the orifices of the lattices have a diameter greater than the diameter of the sleeve and washers are arranged in the sleeve, each interposed between two conductive sheets adjacent. These washers make it possible to ensure the electrical conductivity between the sleeve and the electrically conductive sheets.
    However, these washers are set up manually. This implementation is long and expensive.
    The second object of the present invention is to reduce the time and cost of mounting the sleeve to the super-insulation mattress. For this purpose, the present invention provides a method of mounting an assembly member to a super-insulation mattress.
    This method can be used to assemble from one to twenty-four conductive sheets 4. This method makes it possible to mechanically assemble and simultaneously make an electrical connection between the conductive sheets and a hollow rivet or a female part of the electrical connection device according to the invention. present invention. In the latter case, the female part of the connection device comprises the washer, the sleeve and the elastic element and the male part comprises the conductive pin.
    This assembly method comprises the following steps: - making a through hole 26 in the conductive sheets 4 of super insulation mat 6; - Pressing the sleeve 12 of the electrical connection device 2 or any other rivet in said through holes 26 so as to press the conductive sheets 4 against said flange 22; - Laying said washer 10 on the conductive sheets 4; - Establish a stop on the free end 18 of the sleeve 12, said stop being clean to apply on the conductive sheets a force between 20 Deca Newton and 60 Deca Newton.
    Advantageously, this force ensures the permanent and permanent electrical connection between the conductive sheets, the sleeve, the flange and the washer without requiring the use of washers interposed between the conductive sheets or adhesive bonding of an intermediate adhesive.
    Preferably, the diameter of the through orifice 26 is substantially equal to the outer diameter of the sleeve. Thus, the through holes are fitted against the sleeve so as to ensure electrical contact between the edges of the conductive sheets and the outer face of the sleeve.
    According to one embodiment of this method, the abutment is established by stamping the free end 18 of the sleeve 12. This stamping is obtained by applying a pressure of between 250 deca Newton and 600 deca Newton using a tool adapted.
    According to another variant, the stop is established by threading the free end of the sleeve 12 and by screwing a clamping screw thereon. Clamping can be done manually or automatically using a machine.
    Alternatively, the assembly method according to the invention can also be used with a simple hollow rivet. Any tool for applying residual pressure to the calibrated super insulation blanket sufficient to provide electrical and reproducible contact may be used.
    This method is independent of the electrical connection device described upstream. The applicant reserves the right to file a patent application only for this one.
