Definitions

  • the present invention relates to the field of contactors electrical, and more specifically to so-called "double contactors" race".
  • This type of contactor essentially comprises a button whose a first movement in an actuating direction allows activate a first contact, while a displacement additional, in the same direction, leads to the commissioning a second contact.
  • Generally used contacts only have a rest position corresponding for example to the opening of an electrical circuit.
  • the object of the invention is to propose double-stroke contactors which with no free transmission element (s), and the number of parts components is reduced to the maximum, thus limiting their production cost.
  • the double-stroke contactor of the invention comprises a button with at least one actuation direction mounted in a housing, a first stroke portion of the key in said actuating direction at from its equilibrium position allowing the actuation of a first contact, a second stroke portion allowing the actuation of a second contact, the actuation key comprising, on its face facing the contacts and for each actuation direction, an elastic member capable of acting on the first contact during the first stroke portion, without limiting said stroke, and a second member capable of acting on the second contact during the second portion race.
  • the elastic member consists of an arm provided with a branch elastic provided at its end with a support zone intended to act on the first contact, said branch being able to deform elastically to leave the second portion of the button stroke continue until the second contact.
  • the energy accumulated in the elastic organ during the displacement of the key allows it, in addition to its main function of pressing the first contact, to favor the recall of the key to its initial position.
  • the elastic member consists of an arm provided with a elastic branch provided at its end with a support zone intended to act on the first contact, said branch being able to deform elastically to leave the second stroke portion of the button continue until the second contact.
  • the organ acting on the second contact preferably consists of a finger rigid also provided at its free end with a support zone intended to act on said contact.
  • the second organ can have, like first, elastic properties that further improve the return to the balance of the key by increasing the energy which can be restored when the key is not no longer operated.
  • the respective support zones of the rigid finger and the arm with elastic branch may for example take the form of a conical-shaped protuberance or hemispherical. This particular shape allows precise centering on the contacts, guaranteeing the effectiveness of the transmission of the action to which they are subject.
  • the actuation key is mounted swivel in the housing.
  • the choice of a rotary control mechanism does not result no binding technical necessities, but rather imposes itself because it is more easily generalizable when the number of contacts to be actuated increases.
  • the elastic branch actuating the first contact is for example arranged substantially perpendicular to the pivot axis of the key.
  • the latter can be configured in toggle. She is then well supported pivoting in the housing and has, on its side facing the contacts, and active on each side of a central axis, an elastic member of actuation of the first contact and a fixed actuator of the second contact.
  • said key makes it possible to act for example on four contacts, two contacts on each side of the tilt axis.
  • This solution illustrates the possibility mentioned above of extension of the number of actuated contacts.
  • the pivot axis is then arranged transversely and at center of the button. This characteristic allows a "balanced" use of the touch, in terms of tactile sensations, since a switch in both sense produces the same impression for the user.
  • the second stroke portion of the actuation key must of course be less than residual angular movement allowed by the elasticity of the branch when the first contact is closed.
  • the elastic branch is therefore never stressed in rupture.
  • the key In its flip-flop configuration applying to four contacts, the key preferably has a double symmetry with respect to a transverse plane median and to a median longitudinal plane, which also contributes to a sensation identical operation for both directions of tilting.
  • the case has a look rectangular and has an upper opening housing the button actuator, the side walls of which each have a pin arranged coaxially with the other and coming to be inserted in orifices formed in two opposite side walls of the housing to allow pivoting of the button.
  • pins and orifices allow a polarization which facilitates mounting in the correct direction of the button. This indeed includes information on the separate effects achieved by switching between the two direction of rotation allowed.
  • the moving parts of the contacts for example conductive pads, are fixed on a flexible tablecloth with elasticity allowing them to be brought back into position stable.
  • These moving parts can also be conductive pads blistering deformables which provide electrical contact and elastic behavior.
  • the pads can be fixed on a sheet or label whose function is only the relative positioning of pellets relative to each other and their handling.
  • This tablecloth can then overcome a printed circuit comprising the fixed parts of the contacts and immobilized in the contactor.
  • This printed circuit then in principle comprises a connector allowing the connection of a counter connector for fixing a bundle of conductors carrying information relating to the state of the contacts.
  • this tablecloth can overcome a portion housed in the housing of a flexible substrate on which are screen printed the fixed parts of the contacts, the electronic diagram and the harness of drivers relaying information. Only the outer end of this substrate is generally provided with a connector.
  • this variant is extremely advantageous because it eliminates additional parts (circuit printed, connector), and leads to much faster assembly.
  • the general reliability of the product is further increased by this decrease in number of component parts.
  • the housing can advantageously be provided with a cover lower acting as bottom, on which is fixed said inner portion of substrate flexible screen printed, the cover being kept immobilized relative to the housing in closed position.
  • the existence of the cover is also beneficial for manufacturing because that it facilitates the fixing of the screen-printed part of the flexible substrate due to direct access to the appropriate surface, without the obstacle constituted by the walls of the housing.
  • This fixing is done for example by gluing, gluing or pinching.
  • said cover is hinged to the housing by means of a hinge flexible film constituting it in one piece with the latter.
  • This characteristic is also eminently favorable in terms of mounting, because it removes on the one hand an additional separate room, and on the other hand increase the speed of assembly by reducing handling for closing, finally facilitating the actual closing operation without risk of lose a free room.
  • the invention can alternatively have only one contact per actuation direction, the other contact actuator being replaced by a simple mechanical contact.
  • contact we generally mean the establishment of an electrical connection, except for cases where it is specified that it is only a simple mechanical contact. This is the case when abutting one element with respect to another without electrical connection establishment. Such a solution is possible in one either of the examples described below.
  • the contactor (1) comprises a actuation key (2) pivotally mounted in a housing (3). It's about a flip-flop configuration, therefore allowing the actuation of four contact.
  • the actuation key (2) which will be described in more detail below. description, has a rectangular parallelepiped appearance, and has a wall upper (4) on which the user exerts pressure on one side or the other pivot axis to activate the contactor in both directions pivoting possible.
  • the housing (3) is also of parallelepipedal appearance and comprises a upper opening (7), in which the actuation key (2) comes position, and a lower opening (8).
  • the housing (3) is also provided with a lower cover (13) which can be folded down view of closing the lower opening (8).
  • This cover (13) has two tongues (15, 16) of perpendicular appearance at its medium plane and each provided with a central light (15a, 16a). These tabs (15, 16) are positioned in shaped recesses complementary (not visible) made in the wall (9) opposite the wall (10) fixing the cover (13). These recesses are provided with projections intended to come and fit into said lights (15a, 16a) to block the cover (13) in locked position on the housing (3).
  • Longitudinal recesses (14) are further formed on the edge lower peripheral of the opposite walls (9, 10). They ensure the correct positioning of the cover (13) so that the fixed and mobile parts of the contacts are facing each other when the cover (13) is closed (see below).
  • the moving parts of the contacts (17, 18, 19, 20) are in these circumstances for example conductive pads (17, 20) capable of cooperating with the fixed parts in several ways.
  • these conductive pads can be fixed on a flexible sheet with its own elasticity, in silicone for example, overcoming a circuit printed or the screen-printed part (29) of a flexible substrate which have especially the fixed parts of the contacts.
  • the fixed parts can be directly implanted in a portion (29a) of a flexible screen-printed substrate (29) housed in the housing (3) comprising both the fixed contacts (29a), the diagram electronics and the harness, which and connected to an external connector (22).
  • This portion (29a) can be glued, pinned or pinched on the surface inner cover (13).
  • the moving parts can take the form of pellets blistering deformable conductors which provide both electrical contact and elastic behavior.
  • the pads can be fixed on a flexible thin sheet which can overcome a printed circuit or such flexible screen printed substrate.
  • FIG. 2 shows the structure of the key in more detail.
  • actuation (2) The latter has on its face (23) oriented towards inside the housing (3) (see FIG. 3) two rigid fingers (24, 25) and two arms (26, 27) angled.
  • the rigid fingers (24, 25) are arranged symmetrically by relation on the one hand to a transverse median plane (P) in which the axis of pivot (30) (see Figure 3), and secondly to a longitudinal median plane (L) perpendicular to the previous one.
  • P transverse median plane
  • L longitudinal median plane
  • Each arm (26, 27) has a rigid part (26a, 27a) integral with the surface (23) of the key (2), spreading it in a direction perpendicular to said surface (23), and extended in a longitudinal direction by a branch elastic (26b, 27b).
  • the elastic branch (26b, 27b) of each arm (26, 27) in fact gradually deviates from the surface (23).
  • the rigid parts (26a, 27a) of each arm are in the plane (P) (visible in Figure 3).
  • Branches elastic bands (26b, 27b) then extend towards the ends of the contactor on the on the other of said plane (P).
  • the elastic branches (26b, 27b) are provided at their end with a stud (28) hemispherical in appearance by which the action on the contacts is exerted.
  • the pin (6) visible in Figure 1 has a section different, in this case lower, than that of the pin (6 ').
  • the holes (11, 12) serving to receive them of course have a corresponding diameter. This characteristic avoids any inversion of the button during its mounting in the housing (3), as already mentioned, and therefore facilitates the task of the editor.
  • Figure 3 provides a better understanding of the operation of the contactor (1). To make it easier to read, only the key is shown in solid lines. actuator (2) and the member on which the movable parts of the electrical contacts (17-20). The housing (3) is represented by a broken line, to locate it in relation to key (2).
  • the elastic branch (27b) of the flexible arm (27) exerts an action against the part mobile of the first contact (19), which changes state and thus puts for example in two-point connection of an electrical circuit drawn on a printed circuit or included in the flexible screen printed substrate.
  • the contact (19) actuated first allows for example to lower a car door window in several discrete positions, while the subsequent change of state of the second contact (20) allows continuous descent from the same window.
  • the same results are reached in the direction of opening of said window.
