Definitions

  • the present invention relates to a system for establishing, in microwave, the electrical continuity between two conductive elements.
  • the object of the present invention is to remedy these drawbacks. It relates to a system allowing, in microwave, almost instantaneous electrical continuity, constant in time and repetitive, between two elements.
  • said washer In order to facilitate, at the same time, the elastic deformation of said washer when tightening said conductive elements and the elastic return of said washer to its resting form when they are loosened, it is advantageous for said washer to have a frustoconical shape .
  • said washer can be made of beryllium copper, optionally heat treated.
  • the washer could be carried by said other of said conductive elements and be brought into contact with the element provided with the circular projection only when said elements are tightened.
  • said means of blockage could be worn by this other item.
  • said blocking means establish a mechanical connection between the central part of the washer and the central part of said recess.
  • said blocking means ensure the centering of said washer relative to said annular projection.
  • these locking means comprise an axis integral with the element provided with the projection, said washer being crossed by said axis.
  • said axis carries a head disposed in the concavity of the washer and serving as a stop towards the outside of the latter.
  • said axis is a screw engaged in a tapping made in said element.
  • Figure 1 is an exploded view, partially in longitudinal section, of an embodiment of the system according to the present invention.
  • Figure 2 shows the system of Figure 1 during assembly.
  • Figure 3 shows the system of Figures 1 and 2 at the end of assembly, but however before complete tightening of the two conductive elements one against the other.
  • the system shown in these figures is intended to establish electrical continuity, in microwave, between two conductive elements 1 and 2, capable of being pressed against each other by means of at least one screw 3, which crosses the element 2 through a hole 3a and which is capable of cooperating with a tapped hole 4 made in the element 1.
  • the element 1 comprises a junction face 5, directed towards the element 2 and provided with a recess 6, which is surrounded by an annular projection 7.
  • the face 8 of the annular projection 7, directed towards the element 2, is advantageously planar and is limited, on the side of the recess 6, by a circular edge 9.
  • a tapped hole 11 for example coaxial with the tapped hole 4.
  • the element 2 comprises a junction face 12 which comprises at least one annular bearing portion 13 capable of being applied against the face 8 of the annular projection 7 of the element 1.
  • a screw 14, provided with a head 15, is capable of being screwed into the tapped hole 11 of the element 1.
  • the system further comprises a frustoconical washer 16, pierced with a central hole 17, and made of an elastically deformable metallic material, such as beryllium copper, which may have been treated thermally to increase its elastic deformability.
  • the diameter of the washer 16 is greater than that of the circular edge 9.
  • the screwing of the screw 14 into the tapped hole is preferably continued until the convex surface of the washer 16 comes to bear against the internal circular edge 9 of the annular projection 7 (see FIG. 2). It is also preferable that, in this position, the head 15 of the screw 14 bears against the concave surface of the washer 16 and that the periphery of the central hole 17 is pressed against the bottom 10 of the recess. In this position, the screw 14 may or may not exert a pressure stress on the washer 16. In addition, this position, as shown in the figures, can correspond to the maximum screwing of the screw 14 in the tapped hole 11.
  • the washer 16 may, at this time of assembly, not not be made rigidly secured to the element 1 by means of the screw 14.
  • this screw 14 can only provide a loose connection between the washer 16 and the element 1, said washer then being able to slide from in a limited manner on the screw 14 between two stops constituted respectively by the internal circular edge 9 of the projection 7 and by the head 15 of the screw 14.
  • the element 2 After placing the washer 16 on the element 1, the element 2 is brought closer to it and the screw 3 is screwed into the tapped hole 4. During this screwing, the annular bearing portion 13 of the junction face 12 presses the peripheral part of the washer 16 in the direction of the face 8 of the projection 7. The screwing of the screw 3 is continued until this peripheral part of the washer 16 is strongly pressed between the face 8 of the projection 7 and said annular bearing portion 13.
