Definitions

  • the invention relates to a female terminal for electrical connection having a housing for the male tab of the connection and composed of a sole, a half-barrel and two side walls whose two free edges are curved above the sole, the latter having a locking tab provided with a locking latch snapping 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, subjected to a downward movement, this locking tab provided with the locking lug comprising a “U” shaped cutout, the front cutout of which is located on the side of the locking lug, this cutout defining a folded tongue practically perpendicular to the tab upward and projecting beyond the rear edges of the curved edges of the two side walls integral with the sole, said tongue comprising with an upper end folded in the direction of the half barrel.
  • This type of female terminal finds its application in all the electrical industry, and more particularly in the automobile electrical industry, where one needs to establish a large number of reliable connections, while being easily unlockable.
  • a female terminal for electrical connection corresponding to the preamble of claim 1.
  • Its release member is constituted by a tongue cut out from the locking tab, and folded upwards, perpendicular to it. The upper end of this tongue projects beyond the rear edges of the curved edges of the side walls integral with the sole, and moreover, it is folded in the direction of the half-barrel of the thimble so that it can be easy. accessible and maneuverable when unlocking the terminal.
  • the lug locking tab is extremely fragile and constitutes the weak point of the connection. Also, any improper handling, especially during unlocking, may result in the destruction of the connection, or the existence of poor electrical contact between the male tab and the female terminal. More specifically, when unlocking the connection, it is necessary to press on the projecting tab so as to push the locking tab down as known per se, and thus release the locking pin retained in the lumen produced in the tongue male. During this maneuver, it frequently happens that the force applied to the tongue causes the locking tab to pass through the “U” cutout in the sole, thus causing an exaggerated flexion of the latter, greater than the elastic limit of the metal. . Therefore, the locking tab can no longer return to its initial position, and subsequent contact between the female terminal and the male tongue may be of poor quality, or even non-existent.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims solves the problem of providing the female terminal with means making it possible to limit the downward movement of the release member, and to make it undergo only slight displacements, in order to avoid fatigue and permanent deformation of the metal while taking advantage of these travel limitation means to block the terminal in its insulating housing.
  • the advantages obtained thanks to this invention consist essentially in that the risk of excessive deformation of the locking tab being eliminated, an operator can easily handle the female terminal without damaging it, and moreover, without fear of separating the terminal from its insulating housing.
  • Fig. 1 shows, in elevational view partially in section, a connection comprising the female terminal according to the invention
  • fig. 2 shows a plan view of this connection
  • fig. 3 shows an elevational view partially in section of a connection comprising the female terminal according to the invention
  • fig. 4 shows an elevational view partially in section of the female terminal according to the invention, connected to a male tab
  • fig. 5 shows an elevational view partially in section of the female terminal according to the invention, the terminal being positioned in a connector and shown during the unlocking phase.
  • connection 1 consists of a female terminal 2 and a male tab 3, both made of an electrically conductive material.
  • the male tongue 3 has a bevelled attack edge 7, as well as a light 5 made in its body.
  • the female terminal 2 has a sole 12 serving as a support, on the one hand, for a half-barrel 13, and on the other hand for two side walls 14 and 15.
  • the half-barrel 13 allows the connection of the female terminal 2 with an electrical conductor (not shown), the latter being crimped in the half-barrel 13.
  • the side walls 14 and 15 have their free edges 18 and 19 curved above the sole 12, so as to delimit a housing 23 which constitutes a receptacle for the male tongue 3.
  • the female lug 2 further comprises a locking tab 27 intended to retain the male tab 3 in the housing 23.
  • This locking tab 27 is obtained by a cutout made in the sole 12, and having approximately the shape of a "U”, the branches of which are directed towards the front edge 6 of the female terminal 2.
  • the locking tab 27 has a resilient locking lug 4, and protruding from the top of the locking tab 27.
  • the latter further comprises a release member 11 enabling the connection 1 to be unlocked. .
  • This release member 11 is composed of a tongue 32 obtained by a second cut in the shape of a "U” produced in said locking tab 27.
  • the tongue 32 obtained by this cutout is folded upwards along a fold line 33 situated or beyond the rear edges 34, 35 of the free edges 18, 19.
  • the upper end 36 of this tongue 32 is curved in particular in the direction of the half-barrel 13 to form a heel 37 facilitating the manipulation of the tongue 32.
  • the locking tab 27 which has been given a certain fold around the fold line 28, is located above the sole 12 and parallel to it when the housing 23 is empty.
  • this locking tab 27 is greater than the free space 30 located between the curved edges 18, 19.
  • connection 1 when the connection 1 is locked, the male tab 3 is inserted into the housing 23 of the female terminal 2 until the locking lug 4 is opposite the lumen 5 and comes, due to elasticity, snap into it, thus locking connection 1.
  • these means for limiting the downward movement of the release member 11 consist of a stopper 43 secured to the sole 12 and located in particular but not exclusively at of the front cutout 24.
  • This stop 43 can be obtained from the front cut 24 corresponding to the base of the "U” cut, by stamping or by stamping part of the peripheral zone of the cut 24, integral with the sole 12.
  • This operation has the effect of creating a flattening and a projection of the peripheral zone of the front cutout 24, thus forming the stopper 43.
  • the locking tab 27 is, at least on its end portion 44 comprising the tongue 32, inclined upwards by compared to the sole 12.
  • connection 1 being in the locked position, the male tab 3 is pressed against the edges 20, 21 of the female terminal 2, due to the upward inclination and the elasticity of the locking tab 27.
  • the female terminal 2 in conjunction with an insulating housing 45, it comprises means making it possible to keep it integral with the latter during unlocking.
  • the insulating housing 45 preferably has an oblique ramp 50 arranged on its upper internal face 51.
  • the connection 1 is unlocked by pulling the housing 45 to the right (fig. 5)
  • the locking tab 27 is actuated downwards by the oblique ramp 50.
  • the stopper 43 stops this downward stroke of the locking tab 27. Therefore, during unlocking, the top of the tongue 32, in contact with the oblique ramp 50 of the housing 45, makes it possible to retain this so that it remains attached to the female terminal 2.
  • the release member 11 of the female terminal 2 also constitutes, in cooperation with the stopper 43, a particularly simple and economical blocking means of the insulating housing 45.
