Definitions

  • the present invention relates to a system indicating the quality of the clamping of at least one electrical conductor in the connection terminal block of an electrical appliance, for example a modular appliance of the circuit-breaker type or equivalent.
  • This system is intended to be implemented in a terminal block of the cage and screw type driven by a relative movement in the housing of the device.
  • the displacement results from the manipulation of a control member to tighten / loosen the conductor or conductors between the terminal and the moving element.
  • connection terminals fitted to the devices forming the conventional electrical installations In general, it is in principle advisable to tighten at regular intervals the connection terminals fitted to the devices forming the conventional electrical installations. This is one of the tasks of maintenance departments in the industry, who theoretically check from time to time the quality of the tightening in the installations for which they are responsible. Such work, while it may seem tedious, represents an additional guarantee in terms of overall operation of the entire electrical installation, and also improves the safety of users.
  • a possible solution has for example been disclosed in the document EP-0 854 539 , for a terminal block configuration in which a clamping screw is movable relative to a receiving housing of the conductors which results from a simple recess of the frame.
  • This screw can rotate in a captive nut rotating in said frame, a space in the latter allowing it to progress to the head of the screw when there is clamping.
  • a spring is interposed between said nut and the wall of the frame supporting the head of the screw, the function of which is in particular to compensate for any loosening.
  • An indicator light may also be provided, for example in the form of a tongue which is close to a wall of the frame as the nut approaches.
  • the objective of the present invention is to find a solution adapted to these terminals, and capable of giving a clear and immediate information of the state of the clamping of the terminal to which it is applied.
  • the terminal blocks concerned are composed of a terminal fixed to the housing of the apparatus, a cage and a clamping / loosening member or conductors in contact with the terminal, the latter being driven by a movement relative axial in the housing.
  • the system of the invention comprises resilient compensation means to loosen compensation, and optionally an indicator member reporting the information of the state of the clamping at at least one of the walls of the housing.
  • this system is such that the fixed element and the mobile element of the cage / clamping member torque are reversed from a clamping threshold determined by the return means, which exert a force of non-collinear axis to that of the relative displacement of said elements, against conversion means of the direction of the force transmitted by the element which moves second.
  • the idea underlying the invention is as follows: as long as the movable element first moves so as to trap the conductor or drivers between it and the fixed terminal without there being any effort to tightening, the conversion means of the invention remain stationary. At the beginning of the tightening, when the tightening force is still weak, they are still immobile. From a certain threshold, which is directly fixed by the resistance offered by the return means, they begin to move in a direction such that they solicit said return means, as well as the indicator of the state of the Tightening.
  • the return means serve firstly to compensate the force applied to the clamping, and can also have a calibration function since they decide the threshold from which they come into action, allowing a displacement of said conversion means and the indicator of the state of the clamping.
  • these conversion means comprise a part able to move parallel to the axis of displacement of the successively movable elements, moved by the movable element second, guided in translation along this axis in the housing of the apparatus, and a portion of which is in contact with a movable cam and urges the displacement thereof against the elastic means.
  • the conversion means are therefore based on a cam, which is interposed between a part directly actuated by the movable second element and the elastic return means.
  • the cam does not move in the same direction as the part actuated by the control member, but in the same direction as the restoring force.
  • the cam has a triangular-shaped section, the portion of the part exerting an action on the cam resting on the inclined plane corresponding to the hypotenuse of the triangle, whose perpendicular side to said action is guided in the housing in translation axis perpendicular to said action, the elastic means exerting their antagonistic action on the third side.
  • this piece is a blade of shape perpendicular to the axis of displacement of the movable elements.
  • the indicator member may be rotatable in the housing of the apparatus, its end remote from the transmission means cooperating with a window formed in a front of the housing of the electrical apparatus, to provide information on the quality of the tightening.
  • Such a configuration makes it easy to postpone information on the degree of tightening at the level of the facade in which the control member is accessible, for example near it.
  • the purpose is of course to obtain the information at the facade visually most accessible to the user, when facing for example the switchboard comprising the electrical product provided with the invention.
  • said indicator member is a pivoting arm in the housing, provided with a branch whose end near said window comprises a platform whose degree of centering with respect to this window depends on the clamping.
  • the nature of the information that is communicated is then essentially visual: it suffices, for example, to organize a color coding immediately giving the information to the user.
  • Said platform can thus be coated with a bright color, and be sized to fill more or less the viewing window, to provide the user with instant knowledge of the quality of the clamping.
  • the return means consist of two spring washers arranged one against the other, symmetrically with respect to their contact plane. Their convexity can be oriented outwards or inwards.
  • These washers may for example be of the Belleville type, stiffness chosen according to the resistance that we want them to take, and therefore the degree of tightening which the indicator organ must testify.
  • These elastic return means create a compensatory force whose function is, besides the calibration of the clamping, to cause a displacement of the cam towards the cage during a loss of clamping, and consequently a displacement of the indicator member reflecting releasing said clamping.
  • the system of the invention is purely mechanical, and directly uses the clamping force of the conductor or drivers. It has the advantage of being active throughout the life of the product, because of its design using the compensatory force of the return means.
  • the respective displacements of the various members and / or parts participating in the invention are obtained in particular by means of guides supported by the housing of the apparatus in which the system of the invention is installed.
  • the blade can be moved by the control member of the tightening / loosening, and be located in the cage above the portion of the terminal integrated in said cage.
  • the blade can be moved by the cage, and be located near the wall of the latter placed under the portion of the integrated terminal in said cage.
  • the part actuating the cam of said conversion means may be secured to the movable element second.
  • it can take the form of a shaft passing through the cage, connecting its parallel walls to the axis of movement of the movable elements.
  • the latter has a second branch whose end is in the vicinity of the cam, with which it cooperates to reflect the movement to the arm.
  • This second branch comprises an elongate orifice in which is housed free in rotation a lug of the cam, this connection allowing a double degree of freedom in translation along the axis of the orifice and in rotation.
  • the second branch can be connected in a pivotal connection directly to the cage, when it constitutes the second movable element.
  • This configuration also has the advantage of great mechanical simplicity.
  • control member is preferably a screw cooperating with a threaded hole made in the cage.
  • the operation is then as follows: when tightening one or more conductors, the user raises the cage or down the screw by screwing until the conductor or drivers are imprisoned in contact with a part of the terminal, and on the other hand the wall of said cage facing it or the screw.
  • the clamping force continues, it reaches the threshold set by the return means consist of two washers in contact with the cam.
  • the threshold set by the return means consist of two washers in contact with the cam.
  • the clamping force makes it possible, after exceeding this threshold, for the second movable element, respectively the screw or the cage, to slide inside the cam and driving the workpiece actuating the cam.
  • the centering of the end platform of the indicator member is obtained for a more or less significant clamping force. As soon as this centering is achieved, the clamping is considered correct in relation to the operating constraints of the product in an electrical installation which is at the origin of the choice of elastic means.
  • Loosening involves a relaxation of the action exerted on the workpiece resting on the cam. This release is immediately compensated by the restoring force, which pushes the cam towards the cage, and therefore slightly displaces the indicator member, which is decentered with respect to the viewing window. The user knows at first glance that loosening has occurred, and that he must fix it.
  • the terminal block which is represented in figure 1 conventionally comprises a cage (1) and a screw (2) serving as clamping / loosening member.
  • the cage (1) slides relative to said screw (2), and also relative to a terminal (3) fixed relative to the housing of the electrical apparatus.
  • the conductor or conductors (not shown) are sandwiched between the lower wall of the cage (1) and said terminal (3).
  • the invention itself comprises in the first place a blade (4) in continuous contact with the screw (2), which can slide in the same direction as the cage (1), guided for example by recesses (5, 5). ') formed in the wall of the housing, in which are housed lugs (6, 6') located laterally at the ends of the blade (4).
  • the blade (4) is further guided in a window (7) of the cage (1), via a protrusion (8) arranged centrally on one of the lateral edges of the blade (4), between said lugs ( 5.5 ').
  • One end of said blade (4) is supported on a cam (9) whose section is triangular, the support then being on an inclined plane.
  • This conventional mechanical configuration makes it possible to convert a translation movement in a secondary direction perpendicular to the initial direction.
  • the base of the cam (9) rests on the reliefs of the housing (10) which ensure its horizontal trajectory.
  • the vertical aspect side is in contact with elastic washers (11) Belleville type, arranged against each other, symmetrically with respect to their contact plane.
  • the washer (11) farthest from the cam is in contact with a relief or a rib (12) of the housing or fixed relative thereto, on which it rests.
  • the blade (4) is driven by the screw (2) in translation downwards.
  • the end of the blade (4) in contact with the cam (9) moves the latter in the direction of the washers (11), displacement which in turn allows to move the indicator member (13).
  • This is driven by at least one lug (15) attached to the cam (9), which is inserted into a suitably shaped orifice (16) formed in one end of the indicator member (13), and it then pivots about an axis (14).
  • the lug (15) protrudes from one of the lateral faces of the cam (9), and is housed in an oblong orifice (16) disposed at one end of one of the branches of the indicator member (13), branches extending on either side of the pivot axis (14).
  • the free end of said member (13) comprises a platform (17) positioned near a window (18) formed in the front (F) of the housing of the apparatus in which the invention is installed.
  • the pivoting movement of the indicator member (13) allows said platform (17) to move opposite the window (18).
  • the size and the relative positioning of the various components forming the invention, as well as their mechanical characteristics (in particular those of the return means) are provided such that when the tightening is considered correct, the platform (17) is centered with respect to the window (18). In the configuration shown, when the device is not in the clamping phase, that is to say when the cam (9) moves to the right of the figure, the platform (17) consequently moves to the left, and is off-center with respect to the window (18).
  • the compensation force exerted by the return means indeed applies to the cam (9), which pushes the blade (4) upwards and rotates to the left the indicator member (13) and the upper platform (17).
  • This may for example be coated with a bright color and be of equivalent size to that of the window (18), so that when there is off-centering, only a portion of the window is colored, showing immediately to the installer that there is loosening of the connection.
  • the figure 3 also relates to a direct clamping terminal block, but for a variant without blade (4) mobile.
  • the part which is intended to move the cam (9) is a shaft (19) fixed between two lugs (20) facing each other and protruding from the vertical walls of the cage (1).
  • the operating principle does not change on the bottom: said shaft (19) is now the part that acts on the cam (9).
  • This figure also shows a variant configuration for the indicator arm (13), the second branch is pivotally mounted to at least one of said vertical walls of the cage (1). This solution could of course also be exploited in the configuration of the figure 2 .
