Definitions
- the present invention relates to a switch for detecting the presence of an electronic memory card, also called an integrated circuit (s) card with contact, in a read-write device.
- an electronic memory card also called an integrated circuit (s) card with contact
- the invention relates more particularly to a switch of the type comprising a body and switch control means with which the front transverse edge of the card cooperates.
- control means are produced in the form of an elastically deformable control blade, one free end of which comprises a ramp which is capable of cooperating with the front transverse edge of the card and which includes an actuation point which acts directly on the triggering member of the switch.
- the control means comprise a lever which is pivotally mounted on the switch and which comprises a spout with which is capable of cooperating the front transverse edge of the card, and an actuation point of the triggering member.
- These designs have the drawback of applying to the card, in the read-write position, an elastic force which urges it in the direction corresponding to the extraction of the card, this force having to be counteracted by additional braking means. from the menu.
- the value of the triggering force applied to the triggering member is directly linked to the position of the card relative to the control blade or to the control lever, in position
- This type of triggering device is particular-
- the object of the present invention is to propose a new design of a switch of the type mentioned above which overcomes these drawbacks.
- control means comprise
- an elastically deformable control blade a first end of which is embedded in a switch housing and the second end of which cooperates with a switch release member, and comprises a control lever which acts on the second end of
- control blade and which is capable of pivoting about an axis parallel to the plane of the card in response to a control force applied to it by the front transverse edge of the card.
- control blade resiliently biases the triggering member in the direction corresponding to the closing of the switch, and the control lever, under the action of the card acts on the second end of the control blade, against the elasticity of the blade, to allow the switch to open;
- the second end of the blade is a free end on which acts a control lever mounted articulated on the body of the switch; - According to a variant, in the absence of a card, the control blade does not urge the trigger member and the control lever acts, under the action of the card, on the second end of the control blade , against the elasticity of the blade, to cause the closing of the switch;
- control lever is made integrally with the control blade, the second end of which it extends;
- the control lever comprises a control ramp with which the front transverse edge of the card cooperates
- the control blade extends longitudinally in a direction substantially parallel to the direction of introduction of the card;
- the lever is pivotally mounted about an axis substantially perpendicular to the direction of introduction of the card;
- the first end of the control blade is embedded in the material of the switch housing;
- the first end of the control blade is fixed by hot riveting in an element of the switch housing;
- the triggering member has a generally convex shape and is elastically deformable to establish an electrical connection between two electrical contacts of the switch in response to an axial triggering force which is applied to it by the second end of the control blade in a direction substantially perpendicular to the plane of the map.
- Figure 2 is a bottom view of Figure 1;
- Figures 3 and 4 are views similar to those of Figures 1 and 2 illustrating a second embodiment of the switch.
- FIG. 1 and 2 There is shown in Figures 1 and 2 a set of switch 10 for detecting the presence of a card C with electronic memory, also called microcircuit card, in a read / write device (not shown).
- the association of the switch with the connector must correspond to the stipulations of the ISO 7810 standard relating to the positioning of the card in read-write position in the read-write device.
- the switch assembly 10 is essentially constituted by a switch housing made of insulating material 10, so as to make the switch either in the form of a discrete component which can for example be mounted on a printed circuit board belonging to the read-write device, or integrated in an electrical connector for the connection of the memory card, the switch housing can then be produced integrally by molding with a part of the housing made of insulating material from the connector or attached to the latter in the form of an appendage to the connector cover.
- the housing 12 delimits an upper face 14, considering FIG. 1, on which is likely to bear and slide the lower face 16 of a card C whose insertion direction I, which is perpendicular to the anterior transverse edge 18 of card C, is shown in the figures.
- the housing 12 defines a housing 20 which opens into the lower face 22 and which is in particular capable of receiving the body 24 of a switch.
- the body 24 has a cylindrical shape and it is only shown in silhouette in FIG. 2.
- the switch 24 is preferably of the type comprising a triggering member 26, of a known design, which is capable of deforming between a stable rest position, illustrated in FIG. 3, in which it has a convex shape, the convexity is turned upwards and a deformed closed position of the switch in which it has a domed shape whose convexity is turned downwards and in which it establishes electrical contact between at least two contact elements of the switch 24 (not shown) connected to output terminals 28 of the commutator.
- control means of the switch 24 comprise a control blade 32 and a control lever 34.
- the control blade 32 is an elastically deformable metal blade, a first end 36 of which is embedded in a housing 38 of the housing 12 and extends in a substantially vertical direction, considering FIG. 1, that is to say according to a direction perpendicular to the general plane of the card and of the upper face 14.
- the first end 36 is connected by a bent portion 38 to the main trunk 40 of the control blade
- the first end 36 can be produced in the form of a plate which extends the main trunk 40 in the same plane and which is fixed in the upper bottom of the housing 38 by hot pin riveting which extend from this bottom through holes formed in the plate 36.
- the second end 42 has a deformation which gives it a convex convex profile facing the triggering member 26.
- the switch assembly 10 is of the normally closed type, that is to say that, in the absence of the card C, the second end 42 of the control blade 32 acts permanently, due to its resulting own elasticity of its initial camber, on the triggering member 26.
- control lever 34 when the card C is in the inserted position, has the function of acting on the second end 42 of the control blade 32, against the inherent elasticity of the latter, to oppose the force which it normally exerts on the triggering member 26 and cause the opening of the switch assembly 10.
- the lever 34 is produced in the form of a rocker.
- the lever 34 is a cut and stamped metal part which has a generally elongated shape in the direction of introduction I and which comprises two lateral articulation tabs 44 which bear on articulation pads 46 formed in the housing 12.
- the pads 46 are formed in the vicinity of the lateral edges 48 of a slot 50 formed in the upper face 14 of the housing 12 and which allows an end portion
- the lever 34 is thus pivotally mounted relative to the housing 12 about a geometric axis X-X which is parallel to the plane of the card C and perpendicular to the direction of introduction I.
- 58 is made in the form of a loop and it receives the free end 62 of an arm 64 complementary to the main part 40 of the control blade 32 which extends parallel to the latter.
- the free end 62 with which the control lever 34 cooperates is located substantially in line with the second control end 42.
- the control blade 32 is sufficiently rigid so that any action of the lever 34 on the arm 64 causes a general elastic deformation of the control blade 32, against its own elasticity, tending to cause it to pivot around the area connection curve 38.
- control lever 34 In its rest position illustrated in Figures 1 and 2, the end portion 58 of the control lever 34 is in the form of an inclined ramp with which is likely to cooperate the front transverse edge 18 of the card C.
- the upper face 14 of the housing 12 also includes a projecting portion 66 which delimits an abutment surface 68 with which the front transverse edge 18 of the card C can cooperate at the end of the insertion path of the card C.
- FIGS. 3 and 4 The embodiment illustrated in FIGS. 3 and 4 will now be described.
- the molded case 12 is identical in all respects to that shown in FIGS. 1 and 2.
- the switch assembly 10 is of the normally open type, that is to say that, in the absence of the card C, the triggering member 26 occupies its stable rest position corresponding to opening the switch 24.
- the control lever 34 is here produced integrally with the control blade 40.
- the end portion 60 directly extends the end 62 of the arm 64, this connection zone 60-62, shaded in FIG. 4, also constituting a point of flexion, the function of which will be explained later.
- the front transverse edge 18 of the card C (not shown in FIGS. 3 and 4) cooperates with the end portion 58 forming the ramp of the control lever 34 and causes a general pivoting of the assembly of the control blade 40 and of the control lever 34 substantially around the curved connection portion 38 which causes a tripping of the switch due to the deformation of the tripping member 26 by the second end 42 of the control blade 32.
- the ramp portion 58 is located below the underside 16 of the card C without then applying any force to the card C against the introductory effort.
- the combination of the dome 26 with the means for controlling its triggering advantageously makes it possible to obtain a "click-clack" sound phenomenon upon triggering.
- a flexible sealing film between the open upper face of the switch and the element 42.
- the film can in particular be adhesive and its periphery is thus glued tightly along the upper edge of the switch body 24.
- the body 24 can be fixed in its housing 20 by a technique of hot riveting of studs (not shown), which replace the legs, elastically deformable 30.
