Definitions

  • the invention relates to shielding straps intended to equip connector housings to ensure electrical continuity between the male and female elements in order to protect the electrical terminals and the signals which they propagate from external electromagnetic interference.
  • the male and female housings of the electrical connectors are coupled according to the male element / female element principle. They are made of metal or other composite material, conductive of electricity, and surround the dielectric linings carrying the electrical terminals which are themselves set back from the interface of the housings so that the latter mate and self-position even before the terminals are connected.
  • the shielding bracelet can, for its part, be produced according to different designs but is, most often, constituted by a succession of contact blades, elastically deformable, positioned in an annular groove formed on the outer surface of the body in projection of the 'male element, said blades being fixed in this groove by a flexible or rigid connecting means.
  • the contact blades consist of spring metal parts having the general shape of a flattened V and open towards the female element, these parts being retained in the groove of the element by one or several elastic bracelets applying the bottom of the V in the throat, while freeing its branches, the ends of which are bent outwards and, before connection with the female element, protrude by relative to the periphery of the body in projection of the male element.
  • the contact blades consist of a strip of spring metal slightly curved in its center to form a flared cup, the two branches of which are folded 180 ° in hairpin, to define two contact wings projecting from the periphery of the body in projection of the male element.
  • These elastic blades are connected together by an uncut portion of the metal of the initial strip and are fixed in the bottom of the groove by a plate resting on a shoulder formed at the entrance of said groove, which plate is fixed to the band. supporting contact blades by crimping, stapling, soldering, gluing.
  • the known armor bracelets and in particular those described above call upon a multitude of separate and independent parts (contact blades, flexible links, crimped or stapled plate, etc.) and their positioning on the body of the connection box is particularly laborious especially when it is necessary to install links on independent contact blades difficult to position individually on their respective seats or it is necessary to crimp, staple or glue the fixing means in a reputed place moreover difficult to access.
  • the invention aims to remedy these drawbacks and for this purpose relates to a shielding strap for electrical connectors of the type comprising contact blades of spring steel positioned and fixed in an annular seat, formed on one of the two housings of connection, by an elastic fixing means, bracelet, characterized in that the contact blades have essentially the form of open loops, elastically deformable, at least one of the ends of this loop being able to move freely relative to the other and the means for fixing the contact blades consisting of at least one flexible annular link housed inside the loops, so that all the contact blades are connected together by this link and form with the latter an easily unitary assembly manipulable.
  • the contact blades have the form of open hair pins whose ends can freely move relative to each other.
  • the contact blades consist of a rectilinear core, provided with a positioning fold, for example a triangular fold whose tip is directed in the direction opposite the bottom of the groove constituting the seat of the contact blades.
  • this core is extended on one side by a curved main branch, the convexity of which is turned in the same direction as the positioning fold and on the other side by a shorter branch folded at substantially 90 °, the ends of the two branches being spaced from one another.
  • the main object of the invention lies in the new design of a shielding bracelet forming a unitary assembly and which can be easily placed on or removed from a connection box, without the need to disassemble itself of said housing.
  • the male and female connection boxes will be respectively designated “male element” and “element female "although in reality the male element may contain the contact sockets and the female element the pins to be introduced into these sockets.
  • the male element consists schematically of a flange 1 on one of the faces of which protrudes at least one projecting body 2 intended to be fitted by simple sliding in the socket which constitutes the female element 3 (figure 5).
  • the male element comprises two projection bodies, each being provided with an annular groove 4 intended to receive the shielding bracelet generally designated by the reference 5.
  • Each projection body 2 comprises an annular chamfer 21 favoring its introduction into the female element 3 which also includes an introduction ramp 31 promoting the guidance and coupling of the two male and female elements.
  • the purpose of the shielding bracelet 5 is to promote electrical continuity between the two male and female elements in order to pick up external electromagnetic interference.
  • These male and female elements are obviously made of an electrically conductive material, for example a metal or a charged synthetic material and are usually connected to ground.
  • the shielding bracelet consists of a plurality of contact blades 6 (FIGS. 3 and 4) held assembled and positioned in the bottom of the grooves 4 by an elastic link 7 (FIGS. 5 and 7).
  • Each contact blade is made of an elastically deformable, electrically conductive material, for example made of spring metal and is shaped as an open loop, the two ends 61 and 62 of this loop being able to move freely one relative to the other. 'other. More specifically, such as visible in FIGS. 3 and 4, the contact blade comprises a main core 63, essentially rectilinear (intended to come to marry the bottom of the groove 4 of the male element), each of the ends of which is folded back to form two asymmetrical branches 64 and 65, the longest branch 64 being curved and the convexity of this branch being directed in the direction opposite to the bottom of the groove 4 serving as a seat for the contact blades.
  • the contact blade comprises a main core 63, essentially rectilinear (intended to come to marry the bottom of the groove 4 of the male element), each of the ends of which is folded back to form two asymmetrical branches 64 and 65, the longest branch 64 being curved and the convexity of this branch being directed in the direction opposite to the
  • the curved part of this branch 64 is extended by a rectilinear portion 66 forming an acute angle with the main core 63.
  • the shortest branch 65 is, in turn, bent at 90 ° and preferably by a substantially greater angle at 90 ° and is therefore oriented in a plane substantially perpendicular to the main core 63, its end 61 being spaced from the end 62 of the branch 64.
  • the central core 63 has a transverse fold 67 which for example takes the form of a triangle, the point 68 of which is directed upwards, that is to say in the direction of the convex part 69 of the loop.
  • This fold which extends over the entire width of the contact blade cooperates with a groove of complementary shape 71 formed on the internal face of the flexible bracelet 7 (FIG. 7) which, here, is of polygonal section.
  • the contact blades 6 are assembled, or more precisely joined together by the elastic bracelet 7, (FIGS. 1 and 5), said bracelet being housed inside the loops constituting the contact blades so as to form a bonding agent. between the different blades.
  • the bracelet 7 is preferably made of an elastically extensible material giving it a radial elasticity so that it can be engaged in the annular seat that constitutes the groove 4 by simple stretching and that it takes its place and self-positions in throat 4 by elastic return.
  • the bracelet 7 is in the form of a continuous closed ring housed inside the contact blades 6, before their conformation in open loop or inserted later using the elasticity specific to the metal which allows a certain deformation without harming the conformation of the loops, the latter resuming their initial shape, after passage of the elastic strap, by simple spring effect.
  • the contact blades 6 are assembled to the bracelet 7 by embedding their positioning fold 67 in the corresponding groove 71 of the connecting bracelet and are positioned and locked in the groove 4 by this bracelet, the width of the contact blades being substantially equal to that of said gorge.
  • the bracelet has (see fig. 8) wider parts 71 at the corners of the case, which facilitates positioning.
  • the wider parts 71 which do not carry contact blades 6, are substantially more rigid than the rest of the elastic link and are positioned at the rounded angles of the corresponding groove 4.
  • the width of these wider parts 71 is for example substantially equal to the length of the contact blades 6.
  • the contact blades have the shape illustrated in FIG. 3, the end 62 of the main branch 64 being located at a distance from the main core 63, pressed into the bottom of the groove 4.
  • the convex part 69 of the contact blades meets the annular chamfer 31 of the female element and the branch 64 disappears gradually as the two male and female elements are introduced one into the other, the convex part of the contact blade constituting the support zone, sliding on the ramp which constitutes the introduction chamfer 31.
  • FIG. 4 shows in solid lines the position of the branch 64 after deformation, that is to say after introduction of the male element into the female element while the line in dashed lines illustrates its original position before deformation as illustrated in FIG. 3. It can be seen that the end 62 of the straight portion 66 of the main branch 64 has slid in the direction of the main core 63, relative to the shorter branch 65 which has not undergone any deformation. At the end of introduction, this end 62 is moreover not in contact with the core 63, which makes it possible to avoid additional forces increasing the forces during the introduction of the housing.
  • the contact blades 6 surround the major part of the body in projection of the male element, these being spaced apart and retained between them by the elastic link 7 in the form of a closed continuous ring.
  • the rounded angles of this projected body are free of contact blades, but this absence does not affect the electrical continuity between the two male and female connection boxes because of the large number of contact blades on each of the four sides of the body. the male element.
  • FIG. 6 shows two contact blades 6 located in the same alignment and self-positioned by their fold 67 embedded in the groove 71 of the flexible bracelet 7.
  • the shape of the projected body 2 of the male element can vary and be, as illustrated in FIG. 2, square or rectangular.
  • this body can be circular without detracting from the concept of the invention and in this case it will suffice to use an elastic bracelet of a shape and dimension appropriate to those of the groove carried by the element. male.
  • the shielding strap according to the invention thus allows self-positioning of the contact blades on the flexible connecting strap in order to form a unitary assembly that can be easily manipulated, also coming to self-position in the corresponding groove of the connection box without making call for subsequent stapling, gluing, crimping or soldering operations.
