    Electrical connector locking and extracting device
    The field of the invention is that of devices for electrical and mechanical connection of electronic equipment in frames to ensure a secure connection. The preferred field of application is that of aeronautics and in particular that of aircraft dashboards comprising several display screens. However, this device can have a large number of applications, especially in all areas of professional electronics that require secure connections.
    An electronic equipment of aircraft dashboard generally comprises a connector on its rear face with several tens of electrical contacts. Therefore, mounting this connector requires both high accuracy and some insertion force.
    Currently, various mechanical and electrical connection systems exist to ensure this equipment assembly under the conditions of electrical and mechanical safety and withstand the environments required for aeronautical equipment. These systems also meet the dashboard mounting specific requirements including ease and speed of assembly.
    A first device is to set up, at the dashboard a fixed frame or "chair" 3 having the connector adapted to the connector of the equipment. This chair also has mechanical guiding means in translation for correctly prepositioning the electronic equipment when it is fixed on the dashboard. Once positioned on the dashboard, the equipment is usually locked by means of a fixing handle which ensures both the mechanical attachment of the equipment and the securing of the electrical contact between the two connectors.
    This connection system has several disadvantages. It is blind, the back of the housing is no longer accessible during the connection. On the other hand, it requires the establishment of large and complex mechanical means, given the level of precision required and the dimensions of the housings.
    A second solution consists in separately making the electrical connection and the mechanical connection. In this case, the female connector of the dashboard is mounted on a sufficiently long electrical strand. The connector of the equipment is first fixed on this female connector. Once the electrical connections are established, the electronic equipment is mounted in the dashboard. The disadvantage of this solution is that the connection of the two connectors requires a certain force for locking or unlocking. Without external assistance, this force is difficult to exercise in that one must not exert significant traction on the electrical strand to not damage it.
    The locking device and extraction of electrical connector according to the invention does not have these disadvantages. It comprises mechanical means facilitating these different assembly operations of the connection. More specifically, the subject of the invention is a device for locking and extracting an electrical connector in an electronic box, said electronic box comprising the electrical base corresponding to said electrical connector, the connection and the extraction of the electrical connector being made in a given direction, parallel to the electrical contacts of the electrical connector,
    Characterized in that said connector being mounted in a mechanical assembly comprising at least one shoulder, the electronic box comprises a mechanical structure comprising at least one movable jaw arranged to grip the shoulder of the connector and to impart to it a translational movement in said determined direction, thereby facilitating the connection or extraction of said electrical connector in its electrical base.
    Advantageously, the mechanical structure comprises a second mobile jaw identical to the first movable jaw, each jaw being disposed on either side of the base and arranged so as to grip the shoulder of the connector and to impart to it a translational movement. in said determined direction, thereby facilitating the connection or extraction of said electrical connector in its electrical base.
    Advantageously, each jaw is mounted on a pivot, the movement of the movable jaw being a rotational movement about said pivot.
    Advantageously, the axis of the pivot being perpendicular to the determined direction, each jaw comprises a lever, the tilting of the lever causing tilting of the jaw.
    Advantageously, the axis of the pivot being parallel to the determined direction, each jaw comprises two jaws, the upper part of the first jaw is in the form of inclined disc, the lower part of the second jaw being arranged to leave a constant distance between the jaws. two jaws, said distance corresponding substantially to the thickness of the shoulder, each jaw comprises a lever, the rotation of the lever causing the rotation of the jaws of the jaw.
    Advantageously, the jaw is movable in translation in a plane perpendicular to the determined direction, each jaw comprising a first jaw having a first inclined flange arranged to slide under the shoulder and a second jaw having a second pan of the same inclination and arranged so as to slide on the shoulder, the translation of the jaw causing the translation of the electrical connector in the determined direction.
    Advantageously, each jaw comprises a locking device in a determined position.
    Advantageously, the electronic box is an aeronautical dashboard equipment. The invention will be better understood and other advantages will become apparent on reading the description which follows given by way of non-limiting example and by virtue of the appended figures among which:
    FIG. 1 represents a general sectional view of a first embodiment of a locking device according to the invention;
    Figures 2, 3 and 4 show the steps of implementation of the previous locking device;
    Figures 5 and 6 show the previous locking device comprising a locking means;
    FIG. 7 represents a perspective view of a second embodiment of a locking device according to the invention;
    Figures 8, 9 and 10 show a general sectional view of a third embodiment of a locking device according to the invention and its implementation.
    The locking and extracting device of an electrical connector is mounted on the rear face of an electronic box. This comprises an electrical base corresponding to the electrical connector to be mounted. The electrical connection between the connector and its base is provided by pins or electrical contacts. Generally, the connection comprises several tens of these electrical contacts. In the following, the direction of connection is the direction parallel to the axis of the pins. The connection and the extraction of the electrical connector are made in the said direction.
    In the locking device according to the invention, the connector is mounted in a mechanical assembly having a shoulder. This shoulder is in the general form of a flat plate surrounding the connector. Generally, standard connectors have a shoulder of this type. The locking device according to the invention easily adapts to all types of shoulder.
    In the device according to the invention, the electronic box comprises a mechanical structure comprising at least one movable jaw arranged to seize the shoulder of the connector and to impart to it a translational movement in said determined direction, thereby facilitating the connection or the extraction of said electrical connector in its electrical base.
    There are different embodiments of this type of locking device. Figures 1 to 5 show a first embodiment.
    In this first embodiment, the housing 1 shown schematically in partial section in FIG. 1 comprises two identical mechanical structures 10 disposed on either side of the location of the base 2. Each structure 10 comprises a pivot 11 of which the axis is perpendicular to the extraction direction of the electrical connector 3. In the case of Figures 1 to 6, this axis is perpendicular to the plane of the sheet.
    Each structure also comprises an assembly comprising two jaws 12 and 13 and a lever 14. The set of mechanical parts 12, 13 and 14 can rotate around the pivot 11. The distance between the jaws is adjusted so as to be able to grasp the shoulder 4 of the electrical connector 3 with a minimum of mechanical clearance.
    Figures 2, 3 and 4 show the method of extraction of the connector 3 of its base 2. Of course, the establishment of the connector in its base follows, without difficulty, the opposite steps. In these figures and those which follow, the white curved arrows represent a rotational movement and the white straight arrows a translational movement.
    When the connector 3 is fixed in its base 2 as shown in Figure 2, the shoulder 4 of the connector 3 is immobilized by the two jaws 12 and 13 of the structures 10. By rotating symmetrically on the two levers 14, the jaws 12 are raised and cause the shoulder 4 of the connector in a translational movement which gradually releases the connector of its base as seen in Figures 3 and 4. In these figures, the curved arrows are representative of the movement levers 14.
    As seen in these figures, the length of the jaw 12 determines the extraction stroke of the connector. The jaw 13 must be sized to let the shoulder 4 escape. The length of this jaw is a function of mechanical parameters such as the thickness of the shoulder and the extraction length. These mechanical parameters are easily adjustable by those skilled in the art. To exert the sufficient extraction force which can be of the order of a few tens of kilograms, it is sufficient to size the arms of the levers 14 accordingly. It should be noted that it is not necessary for the translational movement to fully extract the connector from its base. Indeed, it is usually sufficient to extract a few millimeters so that the extraction force is sufficiently low. The connector can then be extracted completely by pulling on it without any particular effort.
    As seen in Figure 2, in the connection position, the levers 14 are oriented substantially perpendicular to the rear face of the housing. To prevent a false movement or shock does come down and cause partial or complete disconnection of the connector, one can have a locking device on each lever that prevents its rotation. Figures 5 and 6 show an example of a locking device. This locking device comprises a movable part 15 mounted on a pivot 16 disposed on the end of the lever 14. The mechanical structure which carries the pivot 11 has a shoulder 17 in which is housed the moving part 15 when the lever 14 is in position. connection position as seen in Figure 5. In this case, any action on the lever 14 is impossible. To release the lever 14, simply release the movable part 15 of its housing.
    A second embodiment is shown in Figure 7. This figure is a partial perspective view of the part of the housing comprising a locking device according to the invention. For the sake of clarity, the connector 3 is not shown in this figure 7. In this second embodiment, the housing 1 comprises two identical mechanical structures 20 arranged on either side of the base of the base 2. Only one of these structures is shown in Figure 7.
    Each structure 20 comprises a pivot 21 whose axis is parallel to the extraction direction of the electrical connector 3. It also comprises an assembly comprising two jaws 22 and 23 and a lever 24. The set of mechanical parts 22, 23 and 24 is rotatable about the pivot 21. The upper part of the first jaw 22 is in the form of an inclined disc, the lower part of the second jaw 23 is arranged to leave a constant distance between the two jaws, said distance substantially corresponding to the thickness of the shoulder 4. The rotation of the lever 24 causes the jaws of the jaw to rotate. Thus, when the lever 24 is rotated, the shoulder of the connector taken between the jaws of the jaw undergoes a movement in translation which extracts or introduces the connector into its base in the direction of movement. The inclination of the disk of the jaw 22 makes it possible to adjust the extraction stroke of the connector. The second jaw 23 has an angular width less than a full revolution as seen in Figure 7 so as to let out the shoulder of the connector to disengage it from its base. Again, to exercise the sufficient extraction force, it is sufficient to size the arms of the levers 24 accordingly.
    A third embodiment is shown in FIGS. 8, 9 and 10. These figures show schematically in partial section the part of the housing 1 comprising the base 2 and its connector 3. In this last embodiment, the jaw is mounted in a structure 30 or slider movable in translation in a plane perpendicular to the direction of connection of the electrical contacts and parallel to the plane of the rear face of the housing. The structure comprises oblong holes whose direction is parallel to its direction of translation and held in place and directed in translation by fixing means passing through said oblong holes. These means are not shown in FIGS. 8 to 10.
    Each jaw comprises a first jaw said low jaw 31 having a first inclined pan 32 arranged to slide under the shoulder 4 of the connector 3 and a second jaw said high jaw 33 having a second pan 34 of the same inclination and arranged to slide on the shoulder 4. The two jaws are mounted head to tail. The first jaw is disposed at one end of the connector and the second jaw at the opposite end. The jaws may occupy the entire width of the shoulder or only part of it. The distance between them and their difference in height are imposed by the geometric characteristics of the shoulder.
    The translation of the jaw causes the translation of the electrical connector 3 in the extraction direction as can be seen in FIGS. 8 and 9. The translation travel of the connector is regulated by the height of the inclined faces and the force to be exerted on the mobile structure for lifting or lowering the connector by the inclination of said inclined faces. The lower the inclination, the greater the lever arm. When the shoulder escapes the jaws, it can remove without significant effort the connector of its base.
    The translation of the structure 30 can be facilitated by a handle 35 as can be seen in FIGS. 8 to 10.
    In a first variant embodiment, the structure comprises only a first jaw 31 and a second jaw 33 as indicated in FIGS. 8 to 10. In a second variant embodiment, the structure may comprise several pairs of jaws 31 and 33 arranged regularly on along the shoulder. In this case, the shoulder comprises slots allowing the different jaws to move up or down the connector.
    As has been said, the device for locking and extracting an electrical connector in an electronic box according to the invention is more particularly intended for aeronautical applications and especially equipment mounted on the front panel of the dashboard. Once the connector mounted, the housing is then positioned in its housing in the dashboard.
