Definitions

  • the present invention relates to an improvement to electrical connection devices comprising a male tongue of flat rectangular shape which is inserted into a female clip.
  • the tongue has a circular orifice which forcibly engages a stud carried by the female clip, which allows the connection to be locked, see, for example, FR-A-1 278 140.
  • This method of insertion has a double disadvantage: firstly, the pressure force to be exerted on the male and female parts must be sufficiently great for said female part to deform until locking takes place, which sometimes makes editing difficult; on the other hand, it often happens that the deformation of the female clip is such that it remains permanent to a certain extent, so that accidental disconnections can occur.
  • the disconnection of these devices requires the introduction into the clip of a tool to deform it again, which further aggravates the deformation of this clip.
  • the subject of the present invention is an improvement to this type of device making it possible to obtain: a low plugging force; high resistance to extraction; and in addition an easy voluntary extraction.
  • FIG. 6 partially represents the male part of the connection device which comprises a flat and rectangular tongue 1, provided with a central orifice 2.
  • this tongue is fixed to the conductive part of a conductor by a crimped lug and to the insulator which coats this conductor by a clamp crimped onto this insulator.
  • This male tab is of known type and its dimensions are defined by a standard.
  • Figures 2 to 5 inclusive show the female clip 3 which has the general shape of a hollow rectangular parallelepiped, so that the tongue 1 can be inserted therein.
  • This clip 3 comprises, as is known, a terminal 3a intended to be crimped on the conductor and a clamp 3b intended to be crimped on the insulator.
  • the bottom wall or sole of the parallelepiped has a cutout 4, in the shape of a U which defines a central tongue 5, two lateral edges 6 and a front edge 7.
  • the tongue 5 being held only by one side can deform elastically while the edges 6 and 7 are fixed.
  • the end 5a of the tongue is folded down about 45 ° and behind this fold is made an almost circular cut 8 having a radius slightly less than that of the orifice 2 of the tongue 1.
  • the material of the tongue 5 located inside the cutout 8 is slightly bent upwards so as to form a semi-circular lug 9 which projects inside the hollow parallelepiped volume of the clip 3.
  • a small tongue 10 is cut from the tongue 5 and also folded down in the opposite direction from the spout 5a of said tongue 5.
  • the upper wall or cover of the parallelepiped is in two symmetrical parts 11 separated by a cutout 12.
  • the side walls 13 connect the parts 11 to the flanges 6 of the lower wall.
  • the parallelepiped is formed in a metal sheet in a single piece, folded twice on itself, so as to comprise: a bottom wall or sole formed by the edges 6 and 7, as well as the tongue 5 (bottom wall connected to the terminal 3a and the clamp 3b); two side walls 13; and an upper wall, formed of two symmetrical parts 11, which abut one against the other along the line 12.
  • the two parts 11 forming the upper wall are curved in their central part 11 a.
  • connection device The operation of the connection device thus described is as follows:
  • the male tab 1 is introduced into the clip 3 through the orifice 14 (FIG. 2) of the hollow parallelepiped.
  • the portions 1 1 of the upper wall in two parts 11 1 support this tongue 1 downwards and the latter presses on the lug 9 of the tongue 5, which causes the latter to bend elastically downwards.
  • the orifice 2 When the orifice 2 is located above the lug 9, the latter enters the orifice 2 and the tongue 5 straightens.
  • the male tongue 1 is then resiliently sandwiched between the curved walls 1 1 a and the sole of the clip 3 constituted by the fixed flanges 6 and 7 and the movable tongue 5; it is locked in position by the lug 9 which projects into the orifice 2, so that an accidental disconnection cannot occur.
  • This downward traction can be achieved by any suitable means, but it is preferably exercised by means of a special insulating cap shown in FIGS. 7 and 8.
  • the cap shown in these figures is a parallelepiped sleeve 15 made of insulating and fairly flexible material, rubber for example, which is threaded onto the clip 3 as shown in dashed lines in FIG. 2.
  • the upper wall of the sleeve 15 has a projection 16 which makes it possible to immobilize the sleeve 15 on the clip 3 in the vicinity of the terminal 3a and the lower wall has a stop 17 comprising an inclined plane 17a having a corresponding slope or slightly greater than that spout 5a (50 ° for example), this stop 17 extending over the entire width of the lower wall of the sleeve 15.
  • the sleeve 15 thus fulfills both the role of an insulating cap for connection and the role of a disconnection control.
