Definitions

  • the invention relates to a female terminal for electrical connection having a housing for the male tongue of the connection and composed of a sole, a half shaft and two side walls, the two free edges of which are curved above the sole, the latter having a locking tab provided with a locking latch that snaps into a slot made in the male tongue, the free end of this tab projecting beyond the rear edges of the curved edges to form the release member .
  • a female electrical contact terminal made of sheet metal and comprising a housing of cross section roughly in "U" shape, consisting of a sole from which rise side walls, the free edges of which are curved towards said sole, so that a complementary contact tab can be introduced between the base and the curved edges of the side walls.
  • This lug also has a tab made in one piece with the sole and protruding at the front of the latter, that is to say at the insertion end of the tongue in the housing, the tab being oriented towards the rear of said housing, inside of it.
  • the tab located in the housing, has a lug inclined towards the rear of this tab and towards the curved edges of the side walls, so as to be able to be housed in a hole or an opening in the complementary tongue when the latter is fitted. in the housing, in order to lock said tab and thus prevent it from being removed from the housing.
  • the free end of the tab projects beyond the rear ends of the curved edges of the side walls and is bent perpendicularly to the tab while moving away from the sole. This free end of the tab projects from the top of the curved edges and forms a release member.
  • the tab is pushed back elastically in the direction of the sole, moving it away from the curved edges of the lateral walls. Therefore, the latch locking lug is released from the hole or the opening of the tongue fitted into the housing, which allows the tongue to be removed.
  • the tab is folded back towards the rear of the female terminal and it is practically parallel to the sole.
  • the female terminal is made of sheet metal, it is necessary to provide a minimum radius of curvature at the location of the folding towards the rear of the tab, otherwise there is a risk that at this location, the tab will tear transversely along the fold line. Therefore, the terminal has a significant height, a drawback especially when it comes to having the connections in reduced places.
  • a female terminal which is intended to be connected to an electrical conductor and to receive a male tab of corresponding size.
  • This terminal includes a conforming housing for receiving and for being electrically connected to the tongue.
  • This housing includes a soleplate, the upper surface of which is stressed at least in part by the tongue.
  • This housing has an open front end through which the tab is inserted during use. The sole is cut so as to obtain inside the housing a tab integral with the sole and extending in a direction away from the open front end of the housing.
  • This tab comprises a lug which extends towards the interior of the housing and which, in use, engages in an opening formed in the tongue to lock the latter in the receptacle.
  • This tab is spread by bending down the tongue, to extract the lug from the opening and thus release the tongue.
  • the free end of this tab extends upward beyond said sole to facilitate flexing of the tab, the lug being located between the two ends of the tab.
  • a female terminal known from document FR-A-2 412 180 has been designed.
  • This female terminal is produced from an electrically conductive metal sheet suitably cut and folded to present, at a end, means for connection to an electrical conductor and, at its other end, a housing whose cross section affects the shape of a "U" with a sole and two side walls, and intended to receive a male contact tongue of flat section having, at an intermediate point of its length, an opening intended to cooperate with a lug of an elastic retaining tab of the female terminal.
  • One of the side walls of the latter has an extension which is folded so as to extend above the sole.
  • the elastic retaining tab is constituted by a branch of the extension extending from the side of the free end of the housing and folded inside of it in the direction of the end comprising the connection means.
  • the free end of the elastic tab is folded in the form of a hook, passes through a lumen made in the sole and projects from the underside of said sole. Thus, for unlocking, it is necessary to push up the free end of the elastic tab folded in the shape of a hook.
  • This element of the housing known from document FR-A-2 445 633 consists of a tubular body made of molded plastic material and having at least one duct intended to receive the female terminal described above.
  • the internal surface of the wall of the conduit intended to receive the female terminal and intended to be turned opposite the upper surface of the extension comprises a boss having, on the side of the insertion end of the male contact tongue, a steep while, on the other side, said boss forms an inclined ramp so that, when the male contact tongue is put in place, the extension thereof elastically deforms when it meets the boss and then returns to its initial position after crossing the steep.
  • the present invention aims to remedy these drawbacks and solves the problem of creating a female terminal of reduced height, of length in accordance with that of the established standards and the unlocking of which can be done easily without the addition of an additional part. .
  • the invention is characterized in that the locking tab, provided with the locking lug, comprises a "U" shaped cutout, the front cutout of which is situated on the side of the locking lug, defining a tongue which is practically folded back perpendicular to the tab upwards and projecting beyond the rear edges of the curved edges of the two side walls integral with the sole to form the release member.
  • connection 1 made of an electrically conductive material, consists of a female terminal 2, of an electrically conductive material, in particular of sheet metal, and of a male tab 3 fitting into the female terminal 2.
  • Locking is provided between the female lug 2 and the male tab 3 by a locking lug 4 secured to the female lug 2 protruding and penetrating into a lumen 5 formed in the male tongue 3.
  • This locking lug 4 produced in a elastic material, has a certain inclination, the bottom point of which is closest to the front edge 6 of the female terminal 2.
  • the male tongue 3 has a beveled leading edge 7.
  • the female terminal 2 has a sole 12 serving as a support for a half-barrel 13.
  • this half-barrel 13 is crimped the end of the conductive wire (not shown).
  • the sole 12 Upstream of this half-barrel 13, the sole 12 has two lateral walls 14, 15 serving as a lateral guide for the lateral edges 16, 17 of the male tongue 3.
  • the free edges 18, 19 of these lateral walls 14, 15 are curved above the sole 12.
  • the upper edges 20, 21 of these free edges 18, 19 bear on the upper face 22 of the male tongue 3 to eliminate any play between the latter and the housing 23 formed by the sole 12, the two side walls 14, 15 and the upper edges 20, 21 of the two free edges 18, 19, which ensures correct contact between the female lug 2 and the male tongue 3.
  • a second cut is made in the locking tab 27 having the shape of a "U".
  • the front cutout 31 is located on the side of the locking lug 4.
  • a tongue 32 is thus obtained which is folded upwards along a fold line 33 so that this tongue 32 is practically perpendicular to the locking tab. 27 and, consequently, the sole 12.
  • This fold line 33 is located beyond the rear edges 34, 35 of the free edges 18, 19 and, as a result, the tongue 32 protrudes beyond said edges 34, 35.
  • the upper end 36 of this tongue 32 is curved to form a heel 37 facilitating the manipulation of the tongue 32. According to FIG. 1, the upper end 36 is curved in the direction of the front edge 7 but, according to FIG.
  • this upper end 36 can also be bent in the direction of the half-barrel 13.
  • the width of this tongue 32 cut out in the locking tab 27 is smaller than the free space 30.
  • the rear edges 34 are provided, 35 free edges 18, 19 stops 38, 39.
  • the tongue 32 is held forward by the stops 38, 39 and rearward by the half-barrel 13, which stops its deformation.
  • the heel 37 To release the male tab 3, the heel 37 must be pressed and the locking tab 27 is pushed down causing the locking pin 4 to be withdrawn from the slot 5 in the male tab 3.
  • the female terminal can be covered with a unipolar or multipolar cap.
