  locking easily and without risk of deterioration of said female terminal

  the. For this purpose, the invention relates to a female lug for connection

  electrical connector according to claims 1 and 3 of the main patent,

  a housing for the male tongue of the connection and consisting of a sole, a half-shaft and two side walls whose two free edges are bent over the sole, the latter having a locking lug provided with interlocking locking lug

  in a light made in the male tongue, the free end of this

  the tab projecting beyond the trailing edges of the curved edges to form the release member, which is downwardly deflected, this locking tab provided with the locking lug having a U-shaped cutout front cut is located on the side 2- of the locking pin, defining a tongue folded substantially perpendicularly to the leg upwards and projecting beyond the rear edges of the curved edges of the two side walls integral with the sole, said tongue having an upper end folded in the direction of the half-drum, female socket characterized in that it comprises means for limiting the downward movement of the release member of the male tongue during unlocking, while cooperating with means for blocking an insulating casing, to ensure the connection

  between the female terminal and an insulating housing.

  The invention will be well understood with reference to the following description:

  made by way of non-limiting example and to the attached drawing in which

  FIG. 1 is an elevational view partially in section of a

  Anion comprising the female terminal according to the invention - Figure 2 is a plan view of this connection - Figure 3 is an elevational view partially in section of the female terminal according to the invention - Figure 4 is a view in elevation partially in section of the female terminal according to the invention, connected to a male tongue, and positioned in a connector - Figure 5 is an elevational view partially in section of the elements

  of Figure 3 during the unlocking phase.

  Referring to Figures 1, 2 and 3.

  The connection 1 as described in the main patent consists of a female lug 2 and a male tongue 3, both made of

  an electrically conductive material.

  The male tongue 3 has a beveled attacking edge 7, and

  that a light 5 practiced in his body.

  The female lug 2 comprises a sole 12 serving as support, a

  on the other hand, with a half-shaft 13, on the other hand, with two side walls 14 and 15.

  The half-shaft 13 makes it possible to connect the female lug 2 with an electrical conductor (not shown), the latter being crimped

in the half-shaft 13.

  The side walls 14 and 15 have their free edges 18 and 19

  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 includes a locking lug 27

  intended to retain the male tongue 3 in the housing 23.

-3-

  This locking tab 27 is obtained by a practically cut out

  in the sole 12, and having approximately the shape of a "U",

  whose branches are directed towards the frontal edge 6 of the female pod.

  2. The locking tab 27 has a locking lug

  4 protruding from the top of the paw

  27. The latter includes, in addition, a releasing device 11 permitting

  setting to unlock the connection 1.

  This release member 11 is composed of a tongue 32 obtained by a second U-shaped cut made in said tab of

lock 27.

  The tongue 32 obtained by this cut is folded upwards along a fold line 33 located beyond the rear edges 34, 35 of the free edges 18, 19. The upper end 36 of this tongue 32 is bent in particular in the direction of half-shaft 13 to form a heel

  37 facilitating the manipulation of the tongue 32.

  According to the main patent, the locking tab 27 to which has been given a certain folding around the fold line 28, is located above the sole 12 and parallel to it when the housing

23 is empty.

  Moreover, the width of this locking tab 27 is greater than

  greater than the free space 30 between the curved edges 18, 19.

  Thus, during the locking of the connection 1, the male tongue 3 is inserted into the housing 23 of the female lug 2 until the locking lug 4 is opposite the light 5 and comes, because of its elasticity, snap into it, thus locking the

connection 1.

Referring to Figure 4

  It should be noted that, because of its small dimensions and its low mechanical resistance to bending, the locking lug 27 of the female lug is extremely fragile and constitutes the weak point of the connection 1. Therefore, any manipulation incorrect may result in the destruction of connection 1, or the existence of a bad contact

  between the tongue 3 and the female terminal 2.

  It is therefore important to protect the locking tab 27 by subjecting it only to slight movements, to avoid fatigue or

  the permanent deformation of the metal.

  For the connection described in the main patent, this is realized

  only when the travel of the locking tab 27 is effected

  kills upwards, since the upper edges 20, 21 of the wings 14, 15 curved, form stops and limit the raising of the locking tab 27. -

  However, when unlocking connection 1, it is necessary to

  yer on the tongue 32 so as to push the locking tab 27

  downwards and thus release the locking pin 4 of the light 5

  in the male tongue 3. During this maneuver, he frequently arrives

  The force applied to the tongue 32 causes the locking tab 27 to pass through the cutout 25 of the soleplate 12, thereby causing an exaggerated flexing thereof, which is greater than the elastic limit of the metal. As a result, the locking tab 27 can no longer return to its

  initial position, and the subsequent contact between the female lug 2 and the lan-

  Male Watch 3 may be of poor quality or nonexistent.

  The purpose of the present invention is, in particular, to provide

  the female lug 2 according to the main patent, the improvements required to

  to avoid the disadvantages mentioned above.

  Thus, the female terminal 2 is provided with means for limiting

  the downward movement of the release member 11 consisting of

  the locking tab 27 and the tongue 32.-

  In a preferred and particularly simple embodiment of the invention, these means of limiting the downward movement of the release member 11 consist of a stopper 43 integral with the sole 12 and located particularly but not exclusively at the level of

front cut 24.

  This stop abutment 43 can be obtained from the front cutout 24 corresponding to the base of the "U" cut, by stamping or stamping a portion of the peripheral zone of the cutout 24,

secured to the sole 12.

  This operation has the effect of flattening and advancing

  of the peripheral zone of the front cut-out 24, thus forming the

stopper 43.

  Therefore, during the unlocking of the connection 1, the downward movement of the locking tab 27 is stopped by the stopper 43, to limit the bending stress to an acceptable value

  for the metal, that is to say below its elastic limit.

- 5 -

  So that the travel of the locking tab 27 is nevertheless

  enough to allow unlocking by releasing the lock pin.

  4, the locking tab 27 is ,. at least on its terminal part

  44 having the tongue 32, inclined upwards relative to the se-

  12. This has another advantageous consequence since, since the connection 1 is in the locked position, the male tongue 3 is pressed against the edges 20, 21 of the female lug 2, because of the inclination to the

  high and elasticity of the locking tab 27.

  This results in a better electrical contact between the male tongue

  3 and the female lug 2. In addition, this inclination of the locking lug

  The upward path 27 helps to make the release member 11 more accessible.

Reference is made to FIG.

  In the case where the female lug 2 according to the invention is used conjointly

  with an insulating casing 45, it comprises means making it possible to

  keep it secured to it when unlocking.

  Indeed, the insulating housing 45 preferably has an oblique ramp 50 arranged on its upper inner face 51. Therefore, when unlocking the connection 1 by pulling the housing 45 to the right (Figure 5), the locking tab 27 is pressed down

by the oblique ramp 50.

  However, 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, allows to retain this one so that it remains attached to the female lug 2.

  Thus, the release member 11 of the female lug 2 also constitutes

  in cooperation with the stopper 43, a blocking means

  particularly simple and economical insulation housing 45.

  Although the invention has been described in connection with a form of

  particular, it is understood that it is in no way limited and that various modifications of shapes, materials

  combinations of these various elements, without thereby departing from

and the spirit of the invention.
