Definitions

  • the invention relates to an elastic return electrical contact intended to be fitted at the end of a cable.
  • They comprise a contact head which comes into elastic engagement with an antagonistic contact under the action of a helical spring which surrounds a deformable conductor such as a braid, connected to a cable, possibly via a terminal or terminal connection.
  • the invention proposes an electrical contact of this type intended to be fitted at the end of an electric cable or the like.
  • the invention is remarkable in that an area of the cable, known as the retaining area, is immobilized with the blade near the fixing end thereof, while at least one conductor is provided for ensuring an electrical connection between said contact head and the cable retaining area so that the leaf spring allows the contact head to be positioned and provides it with elastic bending, transverse to said blade.
  • the cable can easily be positioned until it is perpendicular to the contact head while the latter, thanks to the blade, not only can have a certain elasticity, but has a constant positioning with respect to when fixing the contact.
  • connection conductor between the contact head and the cable retention zone is formed by the cable itself, said head being secured to the stripped end of the cable, while the retention zone of the cable is spaced from said end.
  • the cable retention zone is immobilized with the blade by crimping or by a clamping device which secures said blade and said cable.
  • connection conductor between the contact head and the cable retention zone, is distinct from the cable, its opposite end.
  • the contact head being fixed to the blade and in electrical contact with the stripped end of said cable then constituting said retaining zone, the conductor being, for example, in the form of a conductive braid.
  • the word cable must be generalized because it could be in this case, for example, a contact pin.
  • connection conductor is fixed to the strip with the end of the cable with which it is in electrical contact, by means of a clamping device.
  • the clamping device comprises a ring inside which is positioned the cable retention zone on which the end rests, on the one hand corresponding to the connection conductor when the latter is independent and is not constituted by the cable itself, thus on the other hand, only a part of the blade, while a screw and a nut fixed to the ring ensure clamping of the blade, cable and any independent connection conductor.
  • a helical compression spring is provided to be housed under the contact head, said spring being intended to be wedged in the apparatus to be fitted, in that that the contact head has a centering pin which is received in the helical spring and / or in that the contact head is fixed to the connection conductor, by crimping, the contact head can in this case be formed directly by a crimping rivet.
  • the blade has in its central zone, a central recess and / or a broken line profile.
  • a contact according to the invention can be used in many devices, but more particularly it can among other things equip a plug with a connection system.
  • the contacts according to the invention shown in the drawings are intended to be arranged each, for example, on a cable 1 or the like.
  • Each contact comprises a contact head 2 provided with a disc 2a, for example of silver, and with a guide pin 2b which will be discussed below.
  • the contact head 2 is fixed to a spring leaf 3 whose shape is perfectly visible in the drawings with in particular a first part 3a substantially planar at the level of the contact head, a median part 3b inclined, a rear part 3c, the part 3b being joined to parts 3a and 3c by forming angles in opposite directions, and finally a fixing part 3d.
  • a stripped part of the cable 1 is immobilized with the part 3c of the spring leaf 3 and constitutes a retaining zone 1 '.
  • the cable retention zone 1 ′ is crimped with the blade which, for this purpose has, in this example, a tubular part 4.
  • the stripped part of the cable 1 extends to the contact head 2 and has at its end a tip 5 (especially useful when the cable 1 is formed of strands as shown in Figures 3 and 4) .
  • the tip 5 is crimped with the contact head 2, while securing at the same time the part 3a of the blade.
  • the contact head advantageously consists of a crimping rivet, the tail of the rivet forming the stud 2b while said rivet is stamped on the washer referenced 2c which is arranged under the tip 5.
  • the clamping device 6 here comprises (FIGS. 2 to 8, but more particularly 2 and 5), a ring 7 inside which the cable retention zone 1 ′ is positioned, a screw 8 and a nut 9 fixed to inside the ring.
  • the screw 8 is provided to pass through the part 3c of the blade and to bear on it by means of a flange 10 ( Figures 2 and 5), studs, as shown, may further be provided on the screw to ensure a certain axial retention while allowing rotation of said screw .
  • connection between the cable 1 and the contact head 2 takes place directly since the stripped part of the cable is crimped with its end piece 5 to said head.
  • the cable retention zone 1 ′ is formed by its end while between said end and the contact head, a deformable conductor 12 is provided, here in the form of a braid.
  • the conductor 12 is provided at each of its ends with a crimping tip 5 and 5 ', the tip 5 being provided as above, to be crimped with the contact head (c' This is also why we voluntarily used the same reference 5 as for the tip of the embodiments described above).
  • the end piece 5 ' (FIG. 5) makes it possible to come into electrical contact with the stripped end of the cable constituting the retention zone 1' in the clamping device 6.
  • FIG. 8 is a perspective view of a connection plug 16 fitted with three contacts C1, C2 and C3 of the type previously described in connection with the last embodiment.
  • the contacts C1, C2 and C3 are intended to be connected to the cables 1A, 1B and 1C respectively.
  • Contacts C1, C2 and C3 here represent, for example, power contacts, and other contacts can obviously be provided, such as control contacts whose connection wires can, for example, pass under said contacts C1, C2 , C3 and / or under cables 1A, 1B, 1C.
  • the contact is then placed in the plug by means of the tabs 3 ′ and 3 ′ of the blade 3 which are introduced into appropriate housings such as grooves or slides, like the groove 17 visible in FIG. 8, provided for the 3 '' tab.
  • the pin 2b of the contact head 2 is housed in the spring 13 wedged in the plug 16.
  • part 3b of the blade is hollowed out allows a better flexibility of the blade, but also a possibility of movement of the conductor 12 (or as the case may be, of the end of the cable), or even an expansion in the case of a braid as shown.
