    [0001] The present invention relates to a device for locking and unlocking a rackable electronic equipment such as a rack-mountable electronic card. Equipment and in particular removable electronic cards that can be connected to a rack-bottom connector are known from the state of the art. In the field of aviation, given the high vibrations incurred by the on-board electronic equipment, among the rackmount electronic card locking systems, it is known to ensure the locking of the card to a bottom of rack by a system of central screw with anti-unlocking vibration. Such a system is effective in maintaining the lock but is expensive and slow at the operational level. Another integrated locking system is also known, by means of inserters, but is limited in the power of locking and unlocking when the number of contacts to be connected becomes important. In addition, the equipment manufacturers, and especially the aircraft manufacturers, are constantly looking for gains in terms of cost, mass, reliability, assembly time during assembly and maintenance time of the various equipment. However, as electronic racks incorporate more and more cards that in turn have an increasing number of contacts to connect, card insertion and retrieval efforts become more and more important. More and more powerful and resistant locking systems are therefore necessary, such as the integrated connection system known from patent EP 2 257 145 B1, which discloses an integrated articulated lever on the back of a rack-mountable electronic card and cooperating with card locking blades that allow you to hang the bottom of rack and, under the action of the lever, to pull the card so as to advance in the rack and lock the whole. However, such locking systems, although increasingly powerful and resistant, are also becoming heavier and more expensive. An object of the present invention is therefore to provide a solution to the aforementioned problems and therefore to provide a quick connection system, lightweight and more economical than known systems, while ensuring a lock at least as effective as known systems.
    [0002] The objective is achieved by a locking device of a rackable electronic equipment, the device comprising a first mounting element and a second mounting element essentially forming an articulated lever adapted to cooperate with at least one locking device of a device rack-mountable electronics for locking said rack-mountable electronic equipment with a rack floor. According to the present invention, the locking device is removable. Thus, instead of an integrated locking system that increases the weight and cost of rack-mountable electronic equipment, the present invention provides removable tooling that can be reused to successively lock or unlock multiple rack-mountable electronic equipment at a rack floor. The device according to the invention can advantageously be left mounted on the back of a rackable electronic equipment once it is locked to a rack, or detached to be reused to lock or unlock other electronic rack equipment. The same device according to the invention can therefore advantageously be used for locking or unlocking a plurality of rackable electronic equipment. A locking and unlocking tool according to the invention thus has a cost and mass advantage, in particular for rack systems accommodating a plurality of rack-mountable electronic equipment. Indeed, rack systems known to the state of the art must account for the additional weight of each integrated locking system in each rack-mountable electronic equipment locked in the rack, and their respective costs. Thus, thanks to the present invention, the more the rack accommodates electronic racking equipment, the greater the weight and cost of hardware is important compared to integrated systems known in the state of the art. This presents a considerable advantage for equipment manufacturers and especially for aircraft manufacturers. In addition, the use of a removable tool allows manual connection or disconnection of electronic rack cards equipped with several tens of contacts with reasonable effort compared to known systems, including those using inserters. Thus, in one embodiment of the present invention, the locking device can be used to lock at least one rack-mountable electronic card in a rack floor. In this case, after insertion of the card into the slide of the rack, the locking device according to the present invention is mounted on the back of the card, then actuated to, in cooperation with at least one locking member of the card, secure the card lock in the bottom of rack. Depending on the needs, the device according to the invention can then be left in place on the back of the card, or disassembled to lock or unlock other cards. Preferably, the first mounting element may extend in a first longitudinal direction and comprise a first end comprising at least one, in particular two, mounting member (s) adapted (s) to cooperate with a respective locking member d electronic rack equipment. In an advantageous embodiment, the first end can thus terminate in a first mounting member, in particular in the form of a U. The device can then be mounted on the back of a rackable electronic equipment so as to cooperate with a pin or an axis of the rackable electronic equipment, in particular a movable locking member of the electronic rackable equipment, and thus to form a locking lever. Moreover, in a preferred variant, the first mounting member may further comprise, in the direction of its first end, a second mounting member projecting substantially perpendicular to the first longitudinal direction, and in particular forming a hook extending towards said first end. Thus the device can be mounted to form a locking lever resting on more than one point, for example two pins or axes, of the electronic racking equipment, one of which can be mobile and the other fixed. Preferably, the second mounting member may be an element for transmitting motion, extending in a second longitudinal direction, and having a first end articulated with respect to the first mounting member. Thus, in one embodiment of the present invention, the second mounting member may be a connecting rod or a similar piece hinged about an axis passing through the first mounting member.
    [0003] In addition, the articulated end of the second mounting element may advantageously be furthermore movable in translation along the first longitudinal direction, in particular by sliding along a groove formed in the first mounting element. Thus, it is possible to ensure the transmission of the lever movement of the locking device so as to cooperate the other end of the second mounting member with other locking members of the electronic racking equipment. Advantageously, the locking device may furthermore comprise a spring arranged in the first longitudinal direction and of which a first end is connected to the first mounting element and a second end is connected to the articulated end and movable in translation of the second mounting element. . It is thus possible to avoid a bad connection by return of the spring. In an advantageous embodiment, a connecting rod cooperating with a spring also connected to the first mounting member can thus provide a sensitive locking by return of the locking tool if the locking is not effective. Advantageously, the second mounting element may comprise a second end comprising at least one, in particular two, mounting member (s) adapted (s) to cooperate with a respective locking member of a rackable electronic equipment. Thus, analogously to the first mounting member, the second mounting member can also cooperate with at least one pin or pin mounted at the rear of the rackable electronic equipment, in particular one or more movable locking members of the 'equipment. In a preferred embodiment, the second mounting member may therefore further comprise, in the direction of its second end, a second mounting member projecting substantially perpendicular to the second longitudinal direction, and in particular forming a hook. extending towards said second end. It is therefore possible to advantageously cooperate the locking device with several fixed or movable locking members, so as to advance a rackable electronic equipment in a rack and lock it with the rack bottom. In an advantageous variant, the second mounting element may further comprise, in the direction of its second end, a locking member fitting into the second mounting element, and in particular forming a hook moving away from said second end. It is therefore possible to cooperate the locking member for example with a pin or a fixed axis in the device to ensure the maintenance of the lock. Preferably, the locking device may further comprise a longitudinally shaped handle in which are partially arranged said first and second mounting members. The device can thus have a housing or a housing in which the mounting elements are arranged and can thus form a removable handle for a rackable electronic equipment. In this case, the first mounting element can be preferably arranged in the handle in the first longitudinal direction and be fixed relative thereto, in particular such that the first mounting member of the first mounting member is projecting relative to the handle, particularly with respect to one end of the handle, in the first longitudinal direction. In a preferred embodiment, the locking and unlocking tool can thus form a removable handle, in which are mounted, on the one hand, the first mounting element in a fixed manner, and on the other hand, the second element of pivotally and / or slidingly mounted. Advantageously, the handle may furthermore comprise at least one visual indicator of a state of locking and / or unlocking. Thus, the device according to the invention can also provide a secure locking controlled by a visual cue. According to preferred embodiments of this variant, a visual cue may be for example a text or a color band indicating the locking state. Preferably, the handle may further comprise a movable locking finger, in particular in translation, capable of displacing, in particular releasing, the second mounting element, in particular so as to facilitate disassembly of the locking device of a device electronic rack. Thus, depending on the position of the locking finger, it is possible to maintain or unhook the locking device of a rackable electronic equipment. According to the embodiment, the device according to the invention can therefore form a removable handle by actuating a locking finger.
    [0004] In this case, it may be advantageous for the displacement to be effected by means of a spring cooperating with the locking finger. In preferred embodiments, the spring may be the same spring that can be used to bias the second mounting member. In other variants, it may also be a second spring which can be arranged also in the first longitudinal direction and cooperate on the one hand with the locking finger, and on the other hand with the second mounting element in order to push the latter from a locked position to an unlocked position for disassembling the locking device of a rackable electronic equipment. In addition, said at least one visual indicator can then be visible according to a position of the locking finger. Thus, it is possible to combine the position of the locking finger with the visual indication of the locking state. Finally, the objective is also achieved by an assembly comprising at least one rack-mountable electronic card equipped with a locking device according to the present invention and its variants. According to the embodiments, the objective is also achieved by an assembly of several rack-mountable electronic cards inserted into a rack, in a locked or non-locked state, in which at least one of the rack-mountable electronic cards is equipped with a device. lock according to the present invention. Thus, a single locking device, in other words a single removable tool, advantageously makes it possible to lock and unlock all the rackmountable electronic equipment of the same rack, or more generally all the electronic equipment of the same type of rack. Therefore, in the case of multiple racks, the invention is all the more advantageous that it allows to use only one tool for assembly of all rackmount electronic equipment of different levels of a multiple rack . The connection mechanism of the rackmountable electronic cards can therefore be simplified compared with known cards of the state of the art and incorporating a locking system. Rackmountable electronic cards that can be mounted using the locking device according to the invention can therefore save weight, cost and simplicity compared to electronic rack cards known in the state of the art. In other words, the invention also allows a lower wear of the locking system and therefore increased reliability compared to known systems. Moreover, in the event of a problem with locking, the invention makes it possible to change only the tooling instead of having to change an entire electronic card, which would be the case for the known cards of the state of the art which integrate the locking system in a non-removable manner. The present invention will be explained in more detail in the following description of advantageous embodiments based on the following accompanying figures, in which: - Figure 1 is a perspective view of an example of a locking device according to an embodiment of the present invention; FIG. 2 is a perspective view of a step of locking a rackable electronic equipment inserted in a rack, and of the locking device of FIG. 1; FIG. 3 is a perspective view of another locking step of the rackmountable electronic equipment of FIG. 2, illustrating the mounting of the locking device of FIG. 1; FIG. 4 is a detail of another locking step of the rackmountable electronic equipment of FIGS. 2 and 3, and of the locking device of FIG. 1, illustrating a locked state; FIG. 5 is a view illustrating a locked state, but in a broader perspective than the detail of FIG. 4; and FIG. 6 is a perspective view illustrating the use of the locking device of FIG. 1 to lock one or more rackmountable electronic equipment in a multiple rack. Figure 1 is a perspective view of a locking tool 100 illustrating an example of an embodiment of a locking device according to the invention. According to the invention, the tool 100 is a removable tool for locking and unlocking an electronic equipment rack to a rack bottom. Contrary to the locking systems integrated into state-of-the-art rackmount electronic cards, the tool 100 is removable and can therefore be used for locking and unlocking several electronic rack-mountable equipment, thus enabling a gain in terms of size and weight. compared to integrated systems, but also in terms of cost of production of electronic cards as they are simplified. As illustrated in Figure 1, a locking tool 100 according to the present invention therefore comprises a first mounting member 101 and a second mounting member 102, which is hinged relative to the first member 101, particularly pivotally. Thus, the tool 100 essentially forms an articulated lever when it is mounted on the back of a rack-mountable electronic card, as in the embodiment illustrated in the following figures 2 to 6. According to preferred and advantageous variants of the 1 illustrates that the tool 100 may comprise an elongated handle portion 103 which may be a housing comprising a groove 104 in which the first mounting element 101 may be accommodated, and preferably fixed. comprise at least one transverse axis for securing the first mounting element 101. In the embodiment illustrated in Figure 1, the handle 103 thus comprises the two axes 105, 106 through the first mounting element 101 so cross.
    [0005] In addition, the two mounting elements 101, 102 may be of elongate shape, for example blades, the first mounting element 101 and the handle 103 then extending in the same direction, which therefore defines a first longitudinal direction relative to the tool 100. The direction in which the second mounting element 102 extends can then define a second relative longitudinal direction of the tool 100, forming an angle with the first longitudinal direction, variable according to the relative position of the two elements of FIG. FIG. 1 further illustrates that, according to preferred embodiments, the second element 102 may be a rod-type blade, one end 131 of which is traversed by an axis 107, also passing through the first mounting element 101, thus forming the articulation, in other words the pivot, between the two mounting elements 101, 102. In addition, according to another advantageous variant, the articulated blade 102, or rather the end 131, can be movable in translation relative to the first mounting member 101, in particular by sliding in a groove 108 formed in the longitudinal direction of the first mounting member 101. Similarly, the axis 107 can cross the groove 108 from one side and slide in lateral grooves 109, 110 also formed in the first mounting element 101, so that the end 131 can slide along the grooves 108, 109, 110, thus forming a slide . According to another preferred variant, FIG. 1 illustrates that in addition to pivoting with respect to the first mounting element 101, during the translational movement in the groove 108, the second mounting element 102 can also be recalled by a spring 111, one end of which may be attached to a pin or pin 112 of the first member 101 and the handle 103 and the other end may be attached to the protruding portion of the pin 107 relative to the groove 109.
    [0006] FIG. 1 also illustrates that, according to other advantageous variants, an end 113 of the first mounting element 101 may terminate in a U-shaped member 114. As also shown in FIG. 1, the member 114 may be salient. in the first longitudinal direction in extension of one end 116 of the handle 103, in other words in extension of the element 101 in its longitudinal direction. The element 101 may also comprise, in the direction of the end 113, another mounting member 115, this time protruding substantially perpendicular to the first longitudinal direction, and forming a hook extending towards the end 113.
    [0007] Similarly, the free end 117 of the second mounting member 102 may extend in the second longitudinal direction by a mounting member 118, which may also be U-shaped, and a second mounting member 119 may be shaped of similarly to the member 115 of the first element 101, namely perpendicularly projecting hook of the blade 102 and extending towards the end 117. As illustrated further examples detailed with reference to Figures 2 and 3 , the mounting members 114, 118 at respective ends 113, 117 of the mounting members 101, 102 are adapted to cooperate with a respective locking member of a rackable electronic equipment. In particular, the members 114, 118 may cooperate with an axis of a respective movable locking member provided at the rear of the rackable equipment. The hooks 115, 119 are also able to cooperate with a locking member of the rackable equipment, in particular with a fixed locking member axis provided at the rear of the rackmountable electronic equipment.
    [0008] According to another still advantageous variant, FIG. 1 furthermore shows that opposite to the projecting mounting member 119 there may be a locking member 120 entering the blade 102 or forming a recess in the blade 102 giving the member 120 a hook shape extending in a direction opposite to that of the hook 119. As illustrated further in FIG. 4, the hook 120 can hook an axis 123 inside the tool 100 so as to ensure the maintaining the lock. FIG. 1 also illustrates that the second end 122 of the handle 103, as well as the second end 124 of the first element 101 can be opened so as to allow the second element 102 to return when the latter pivots towards the locked position, as in FIG. In this case, just above the hook 120, towards the end 117 of the mounting member 102, may be a notch 121 allowing the mounting member 102 to be received in the groove 108, in the locked position of the system, without being impeded by the axis 106. According to yet another variant, the tool 100 may also comprise a locking pin 125, visible in Figure 1, mounted movably on the 103, in particular slidingly, and whose action will be more understandable with the help of Figure 4. Figure 2 is a partial perspective view of a rackmountable electronic card 200 inserted into a rack 300, showing also the locking tool 100 of the embodiment illustrated in Figure 1 before mounting on the back of the card 200. In this step, the electronic card 200 is inserted into the housing 301 of the rack 300 but is not yet locked with the bottom of the rack 302 (not shown in Figure 2, but visible in Figure 5). The insertion can be done manually by sliding the card 200 in a slide (not shown) of the rack 300. The non-illustrated part of the card 200, or "front" part of the card 200, may comprise a plurality of electrical contacts intended to be plugged into the bottom 302 of the rack 300, which may therefore include homologous electrical contacts. The part of the electronic card 200 visible in FIG. 2 can therefore also be called the "rear" part of the card 200.
    [0009] Like some known electronic cards of the state of the art, the card 200 of the embodiment illustrated in FIG. 2 and in the following figures, comprises integrated locking members making it possible to lock it at the bottom of the rack 300. to integrated locking systems known from the state of the art, the electronic card 200 of the embodiment illustrated in Figure 2 does not include an integrated locking lever, the locking being done by mounting and actuating the removable tool 100 of the embodiment illustrated in Figure 1, which, once the card 200 locked in the rack 300, can be removed from the back of the card 200 and reused to lock or unlock other cards. Consequently, the electronic card 200 is lighter and less expensive to manufacture than the known electronic cards of the state of the art with integrated locking system. FIG. 2 further illustrates that the electronic card 200 may comprise at least one movable locking member and at least one corresponding fixed locking member, making it possible to lock it at the bottom of the rack 300 by virtue of the lever effect of the tool 100. Advantageously, in the embodiment illustrated in FIG. 2 and in the following figures, the electronic card 200 thus has pairs of locking members, one mobile and the other fixed with respect to the housing 201 of the card 200, which can cooperate with the pairs of mounting members 114, 115 or 118, 119 of the locking tool 100. Thus, the card 200 comprises the first movable locking members 202 and fixed 204, on the one hand, and the second movable locking members 202, mobile lock 203 and fixed 205, on the other hand.
    [0010] As illustrated in Figures 2 and following, the movable locking members 202 and 203 can cooperate with the mounting members 114 and 118 at the respective ends 113, 117 of the mounting elements 101, 102 of the tool 100. Similarly, the fixed locking members 204 and 205 can cooperate with the hooks 115 and 119 of the locking tool 100, thereby creating the desired leverage effect.
    [0011] FIG. 2 illustrates a possible approach for mounting the tool 100 on the back of the electronic card 200. In this embodiment, the arrangement of the locking member pairs 202, 204 and 203, 205 may be symmetrical, such that the mounting of the tool 100 can be done either according to the illustrated example, or symmetrically. In other words, the pair of mounting members 113, 114 can be mounted in cooperation with the pair of locking members 202, 204, the pair of mounting members 118, 119 then cooperating with the pair of locking members 203, 205, as illustrated in FIG. 2 and following. However, in other embodiments, if the pair of mounting members 113, 114 is cooperatively mounted on the pair of locking members 203, 205, the pair of mounting members 118, 119 will then have to be respectively mounted on the locking members 202, 204 (non-illustrated inverted position of the tool 100). 3 illustrates the locking tool 100 in place on the back of the card 200, the housing 201 has been made transparent to reveal the locking members of the card 200. The mounting member 114 in U is positioned on an axis 206 of the movable locking member 202, the latter further comprising a locking blade 210, one end of which can be wound on the axis 206, the other part (not shown) serving for locking on the bottom of the rack 300. An axle 208 of the fixed locking member 204 can then be hooked by the associated hook 115 of the first mounting member 101. Likewise, the pivotable mounting member 102 may form an angle with the fixed mounting element 101 of the tool 100, which also makes it possible, under the action of the spring 111, to position the other U-shaped mounting member 118 against an axis 208 of the other movable locking member 203, and also to come to pick an axis 209 of the other organ of fixed locking 205 by means of the hook 119. Like the other movable locking member 202, the locking member 203 may also comprise a locking blade 211, one end of which may be wound around the axis 207 and the other end of which part also serves for locking on the bottom of the rack 300. A lever movement tilting the tool 100 towards the card 200 can then allow to pull the card 200 and lock it at the bottom of the rack 300 using the blades of locking 210, 211. By levering the hooks 114, 119 about the axes 208, 209 of the fixed locking members 204, 205, the cooperation of the U-shaped mounting members 114, 118 and movable locking members 202, 203 can therefore allow the locking blades 210, 211 to advance the card 200 to its locked position in the bottom of the rack 300, as illustrated particularly in Figures 4 to 6. Thus, when the locking tool 100 is operated and my In its locking position, the second mounting element 102 is pivoted flat in the groove 108, as shown in the sectional view of FIG. 4, so that the hook 120 hooks the axis 123, the notch 121 surrounds the axis 106, and the free end 117 of the second mounting member 102 protrudes from the end 122 of the handle 103 in a manner similar to the end 113 of the first mounting member 101 relative to the Another end 116 of the handle 103. The spring 111 can be tensioned and cause the mounting members 118, 119 to exert, respectively, a pressure on the pins 207, 209. With particular reference to FIG. electronic card 200 may also include a self-locking or secondary locking system ensuring the maintenance of the card 200 lock in the rack 300 to disassemble the tool 100 for reuse with other electronic equipment rac kables. The card 200 may therefore comprise a locking button 214 cooperating with two secondary locking blades 215, 216 which, as soon as the movable locking members 202, 203 advance under the action of the tool 100, can come stall in secondary stops 212, 213 respectively of the members 202, 203. The stops 212, 213 are shown in transparency in exemplary manner in Figure 3, the stop 212 being further detailed further in Figure 4. In this way, once the blades 210, 211 locking members 202, 203 in the locking position in the bottom of the rack 300, the secondary locking blades 215, 216 ensure the maintenance of the locked position of the main locking blades 210, 211 in the bottom of 302 rack and then allow to disassemble the tool 100 without risk of disconnection. The disassembly of the tool 100 can then be done by actuating the end 126 of the locking pin 125, thus causing the lowering of the locking pin 125, which can finally release the axis 123 of the hook 120, and thus make sliding or pivoting the second mounting element 102 in the groove 108 and around the axis 107 so as to disengage the mounting members 118, 119 of the pins 207, 209. To do this, according to a preferred variant, the locking finger 125 may further comprise a lug 127 which, when actuating the finger 125, can compress a spring 128, visible in Figure 4, which can be connected to the second mounting member 102 of the tool 100. Once the members 118, 119, the tool 100 can be simply removed from the card 200 and reused to lock or unlock other electronic equipment rack, while leaving the card 200 locked in the rack 300 by means of the lock blades secondary generation 215, 216, which are visible in Figure 3 but have been hidden in Figure 4 to detail the stop 212 of the movable locking member 203. Figure 5 illustrates the electronic card 200 locked to the rack bottom 302, with the box 301 of the masked rack 300, and with the locking tool 100 mounted in the locked position. The locking position or state can be indicated in a number of ways, including by means of visual indicators such as text, color bands, combinations thereof or other similar means. For example, FIGS. 2 to 5 show visual indicators 129, 130 of the locking state on the handle 103 of the locking tool 100. In particular, these indicators 129, 130 can be placed on the handle 103, ends of the locking finger 125, so that in the locked state, when the locking finger 125 is in its illustrated up position, an indicator 129 corresponding to the locked state can be seen below the locking finger 125 However, if the locking pin 125 is actuated, Figure 4 allows to glimpse another indicator 130, which will be visible in the lower position of the finger 125, corresponding to an unlocked state to disassemble the tool 100 from the back of a rackable electronic equipment. Similarly, a rack-mountable electronic equipment compatible with the lock tool 100 may itself also include an indicator of a lock state. Thus, as illustrated in Figures 2, 3, 5 and 6, the housing 201 of the electronic card 200 may comprise visual indicators 217, 218, 219, at least one of which may correspond with a visual indicator 221 of the button. locking 214 in a locked or non-latched state of the card 200. For example, in the exemplary embodiments illustrated in FIGS. 2 to 6, FIGS. 2 and 3 illustrate an unlocked state of the card 200, in which the indicator 221 of the button 214 is turned to the unlocked state indicator 219 of the housing 201, while FIG. 6 illustrates a locked state of each card 200 in the multiple rack 300, with the indicator 221 of the button 214 to the locked state indicators 217, 218 of the housing 201. In the illustrated embodiments, each of the U-shaped mounting members 114, 118 at the ends of the mounting members 101, 102 may further be used later in as long as evis in order to unscrew the locking button 214, for example in a direction that can be indicated by a visual indicator 220 on the housing 201 of the electronic card 200, so as to disengage the secondary locking blades 215, 216 stops 212, 213 The card 200 can then be unlocked from the rack 300 by mounting the tool 100 at the rear of the rack, as in FIG. 3, and pulling the tool 100 instead of levering the card 200. FIG. 6 illustrates finally an example where the rack 300 is a multiple rack that can accommodate a plurality of electronic cards 200. The locking tool 100 according to the present invention can therefore advantageously be used for locking or unlocking each card. In particular, a single tool 100 can be used for all the operations of locking or unlocking all the cards 200 of the multiple rack 300. The tool 100 can be Optionally left mounted at the back of one of the cards 200 in its locked state, as in Figures 4 and 5, or it can be detached so as to make the whole more compact and lighter. In any case, the multiple rack 300 filled with electronic cards 200 compatible with the locking tool 100 will be more compact and lighter than if it were equipped with known electronic cards of the state of the art with a integrated lever connection system, which can be a considerable advantage in the case where the multiple rack 300 would be used for the aeronautical industry or any application having constraints on the onboard load. Each rack-mountable electronic card 200 will not only be lighter, but also cheaper than a state-of-the-art rack-mount electronic card incorporating the entire connection system, while retaining all the advantages in terms of the reliability of the locking. In addition, in case of concern with the locking tool 100, only it can be replaced to continue operations on a whole set of electronic cards 200, which has another advantage over the replacement of an entire electronic card with integrated connection system such as those known from the state of the art. As is apparent from the foregoing description, the present invention is not limited to locking electronic rack cards in the field of aviation, but can be adapted to all types of rackmounted electronic equipment used in other fields. However, in the particular field of aeronautics, where the weight of embedded systems plays a predominant role, and in the related fields, the invention has a considerable advantage over the state of the prior art, since only one tool is needed to lock a set of electronic cards to a rack system, which reduces the weight of each card, and therefore the entire rack and embedded electronics, compared to systems known from the state of the art in which the card comprises a built-in locking lever. In addition, the invention has an advantage over known systems of the state of the art, in particular when the connection and disconnection forces become too important for inserter type manual locking mechanisms, or for a gain of time compared to a coupling screw system. It will be further apparent to those skilled in the art that, although the invention has been described with reference to a particular embodiment, it is not limited thereto. In particular, the technical equivalents of the described means as well as the combinations thereof used in the same frame can form more embodiments of the present invention.
