Definitions

  • the invention relates to an elastic return electrical contact intended to be fitted at the end of a cable.
  • the invention proposes a contact of the aforementioned type but which is particularly remarkable in that an area of the cable, called mooring, is fixed to said housing of the device, in the vicinity of the fixing end of the blade and in that the cable has a hook shape between its mooring area and its end provided with the contact head delimiting a free space in its concave curved part, while the contact head has a surface of contact arranged perpendicular to the longitudinal axis of the end of the cable and elastic mobility substantially coaxial with said axis, the blade being arranged in said free space being further biased by a spring fixed to the housing of the device.
  • the work of the constituent strands of the cable is advantageous due to the positioning of the contact head whose mobility is longitudinal with respect to the end of the cable and no longer perpendicular as in the prior art cited.
  • the spring which biases the blade is a helical spring. mounted coaxially on a guide rod which passes through said blade and which is fixed to the housing of the device, the spring being wedged between the blade and an end stop of the rod which preferably crosses the blade through an oblong hole made in the vicinity from the end of the blade secured to the contact head.
  • the contact head comprises a sleeve which covers the end of the cable.
  • the blade is fixed to the contact head by means of an end fork-shaped intended to be housed in one or more grooves provided this effect in the contact head by partially surrounding it.
  • the cable is for example fixed in the housing of the device by means of screws which are fixed in said housing and which pass through said cable.
  • the blade present in a median zone in the vicinity of its fixing end, a central recess and has a broken line profile.
  • such a contact is for example intended to equip a mobile socket of a connection system and more particularly still the socket of a charging connector.
  • Each contact is designed to be fitted at the 1 'end of a cable 1 ( Figure 1) and has a contact head 2 in the form here of a sleeve 2a which covers the end of the cable and which includes a patch 2c, for example in silver, intended to ensure electrical contact with an antagonistic contact of another device with which the plug is intended to mate.
  • the pad 2c which constitutes the contact surface is arranged perpendicularly to the longitudinal axis of the end 1 'of the cable 1 and, as the Figure 1, we understand that the head 2 has a mobility substantially coaxial with said axis, mobility which is also elastic for the reasons which will be mentioned below.
  • the contact head is fixed to a leaf spring 3, as shown in the figures 1 to 3, Figure 3 showing more particularly the blade alone while the Figure 2 shows the blade 3 and another blade 3 'of the same type for another contact.
  • the latter has a fork-shaped end 3a intended to be housed in a groove 2b of the contact head 2 by partially surrounding it.
  • the fork 3a of the blade 3 has two elastic branches terminated by retaining lugs which are forcibly passed, the the ends of the two branches then being tightened by a tool to ensure a perfect attachment of the contact head 2.
  • the blade 3 in addition to its forked end 3a, has a general shape in broken line with a so-called fixing 3d end, opposite the fork 3a and a intermediate zone in two parts respectively 3b on the side of the fork 3a and 3c on the side of the 3d fixing end, the parts 3a, 3b, 3c and 3d being connected between them by zigzagging.
  • the intermediate part 3b is provided with an oblong hole 4 whose length is directed lengthwise of the blade while part 3c has a recess 5 which will be discussed below.
  • the blade 3 is fixed by its 3d end in the housing 6 of the socket shown in Figures 1 and 2, here by means of a screw and a nut.
  • the cable 1 is moored to the housing 6 of the apparatus here by means of screws 7a, 7b which pass through the cable 1 in a zone 1 " mooring while allowing it to be clamped between two elements 8a, 8b while that said cable 1 has the shape of a hook 1 "'between its mooring area 1" and its end 1 'provided with the contact head 2.
  • the blade 3 is arranged in the space delimited by part 1 '' 'concave curve of cable 1.
  • This arrangement makes it possible to obtain the advantages specified above concerning in particular the small footprint, the flexibility of the cable, but also a perfect positioning static (position of the head relative to the blade attachment) but also dynamic thanks to the guidance provided inter alia by the rod 9 in the oblong hole 4.
  • the recess 5 provides a certain freedom in torsion. which can in particular allow compensation for flattening tolerances of the contact head 2 on its antagonistic contact.
