Definitions

  • the present invention relates to a shielded connector housing.
  • boxes are made of an electrically conductive material, for example metal, but it is necessary to ensure electrical continuity between the two elements of the box and to ensure that when connecting the first electrical contact s '' performs at the shielding level and not at the level of one of the connected conductors.
  • the present invention aims to solve these problems in a simple, reliable and economical manner.
  • the subject of the present invention is a shielded connector housing, in which one of the elements of the housing has on its periphery a plurality of elastic contact blades electrically connected together as well as to the housing element which supports them, these blades contacts pressing against the other housing element during connection, characterized in that each contact blade extends substantially in the direction of relative movement of the two housing elements during connection and is constituted by a thin metal blade folded into a U, the free end part of which rests on the housing element which supports it so as to elastically push the useful part of the contact blade outwards in contact with said other housing element, said contact blades being associated with a counterplate which ensures their attachment to the housing element.
  • the contact blades are produced in a metal strip, the part supporting the contact blades is in the form of a continuous band and fixed to the plywood for example by stapling, soldering, gluing or crimping .
  • the contact blades are associated with a counterplate which is provided with openings allowing the passage of the contact blades.
  • the folded part of the contact blades has lateral extensions which protrude outside the openings of the plywood to prevent the contact blades from moving away from the housing element on which they are fixed and to ensure that they can only be moved if a force is exerted on them which exceeds a predetermined value which determines the contact pressure.
  • the contact blades and the counter plate are provided with centering means for correctly positioning the contact blades relative to the counter plate.
  • the contact blades are double, one directed in the direction of the connection movement, and the other directed in the opposite direction, so as to establish on the same generator two contacts, simultaneous or successive.
  • the contact blades have a slightly curved transverse profile in the zone where they come into contact with the housing element on which they are not fixed.
  • FIG. 1 There is shown diagrammatically in FIG. 1 a connector housing comprising a male element 1 which engages in the known manner in a female element 2 while the male contacts 3 connected to conductors not shown engage in the female contacts 4 connected to the corresponding conductors not shown.
  • the elastic contact blades 5 which provide the electrical connection between the two elements 1 and 2 of the housing are arranged on the outer periphery of the male element, but they could alternatively be arranged on the internal periphery of the female element 1.
  • the male member 1 has at its end a bevel 1a to facilitate the centering of the two housing elements during connection.
  • the male element On its periphery, the male element has a recess 6 of shallow depth, the width of which is slightly greater than the width of a counterplate 7 which maintains the contact blades.
  • the male element 1 also comprises two grooves 8, formed in the bottom of the recess 6 and intended to receive the folded ends 5 has contact blades 5.
  • Figure 4 is a top view with partial cutaway of the shielding device, according to arrow IV of FIG. 1, or according to a top view of the male element as shown in FIG. 2, the bevel 1 a of the element 1 as well as the recess 6.
  • the folded lower parts 5 has contact blades are provided with lateral extensions 5 c , which by cooperating with the ply plate 7 limit the outward movement of the contact blades, as will be explained below.
  • the plywood 7 which can be made of an electrically conductive material or of an insulating material is in the form of a rectangular strip, the lateral edges of which come to bear on the bottom of the recess 6 and which is provided with windows 11 whose dimension is slightly greater than the width of the upper part (5b) of the contact blades but less than the width of this upper part (5b) plus the height of the lateral extensions 5 c .
  • the counterplates 7 are also provided with circular recesses 12 in which the bosses 10 engage, which makes it possible to ensure exact positioning of the contact blades with respect to the plywood 7.
  • the counterplate 7 thus positioned can be fixed to the continuous strip 9 which supports the contact blades by crimping, stapling, soldering or gluing.
  • the assembly thus obtained can be cut to the desired length, and shaped so that it can be applied over the entire periphery of the male element by engaging the counterplate 7 in the recess 6.
  • the assembly constituted by the backing plate 7 and the contact blades can be fixed to the male element of the housing by crimping, stapling, soldering or gluing for example.
  • ends of the plywood 7 can only be welded, stapled or glued together to make the plywood assembly 7 and contact blades integral with the housing element without this assembly requiring attachment to the latter.
  • the assembly constituted by the backing plate 7 and the contact blades can be folded easily to go around the element of the housing, where we find the contact blades 5 with their lateral extensions 5 c , as well as the plywood 7 which is seen in section.
  • Figure 2 is when the blade contact left in contact with the frustoconical opening 2a of the female element of the housing.
  • the contact blade 5 on the left is subjected to a prestress, such that it is necessary to make a certain effort to push it down.
  • the left contact blades engage in the recess formed by the larger part 2 c of the female element, while the shielding continues to be provided by the right contact blades.
  • the part of the contact blades which comes into contact with the housing element which does not support them has a rounded cross section both to ensure contact frank electric and to be able to adapt to the curves of the housing as seen in Figure 5.
  • connection boxes it is possible to achieve effective shielding of the connection boxes using a simple device which can be produced continuously in the form of strips, which can then be cut and adapted to the different connector housing shapes.
