    Detailed description of some embodiments of the invention
    In Figs. 1 to 7 shows a first embodiment of a female terminal according to the invention. The female terminal is manufactured from a sheet of metal material punched and folded. The female terminal has a front part 1 that has a housing 3 and an opening 5 through which the insertion head 59 of a substantially flattened male terminal can be inserted (see Figs. 13 to 15). The insertion movement of the insertion head 59 in the housing 3 defines an insertion axis or longitudinal axis of the female terminal. Opposite the front part 1 is a rear part 7 which has fixing means 9 suitable for fixing an electric cable.

    The front part 1 comprises a base 11 that limits the housing 3 on its lower part, two side walls 13, one on each side of the insertion axis, which extend parallel to the insertion axis and which have their origin at the lateral ends of the base 11. The side walls 13 extend upward, forming a right angle to the base. The side walls 13 laterally limit the housing 3. Each side wall 13 has, at its upper end, an extension 15 projecting towards the insertion axis and which delimits, at least partially, the housing 3 at its top.
    The base 11 has an elongated hole 17 defining a main axis parallel to the insertion axis. The elongated hole 17 has a narrow passage 19 of width, measured perpendicular to the longitudinal axis, smaller than the rear end than the elongated hole 17. From the front end of the elongated hole 17 a flange 21 is projected backwards in the direction of the main axis . The flange 21 is made of the original metal sheet material that was in the place where the elongated hole 17 has been made, which saves material. The flange 21 has a head 23 at the rear end of the flange 21. The head 23 is attached to the rest of the flange 21 through a neck 25 where the neck 25 has a width, measured perpendicularly in the longitudinal direction, smaller that the head 23. The neck 25 corresponds to the narrow passage 19 of the elongated hole 17. The flange 21 is bent upwards in a section anterior to the neck 25 so that the head 23 is on the vertical of the narrow passage 19 of the hole elongated 17. The upper end of the head 23 is bent backwards.
    The flange 21 has a retention one 27 that projects towards the housing 3. This one with retention 27 is the one that would be housed in a hole 61 disposed in the insertion head 59 of the male terminal thus making the function of curling. To decouple the male terminal, it is sufficient to press the flange 21 down so that the retention one 27 leaves the hole 61 provided in the male terminal thus allowing its extraction.
    This female terminal according to the invention has a flange 21 with great flexibility. The flange 21 is directly attached to the base 11 and, in addition, is attached to the base 11 on both sides of the flange 21. Additionally, the positioning of the head 23 above the narrow passage 19 means that at no time can it be bent the flange 21 downwards an indiscriminate amount, since the head 23 (whose width is greater than the width of the narrow passage (19)) bumps into the edges of the narrow passage 19. In this way the flexing path of the flange is limited 21. All this allows a female terminal to be offered with a widely reliable enclosure system, which cannot be folded beyond its elastic limit, so it always retains its elastic properties and can be made of
    5

    25

    35
    less flexible materials than those usually used. In particular it can be made of iron and / or iron-based alloys. Iron-based alloys are understood as those in which its major component is iron.
    Preferably, the flange 21 has a fold 29 in the area of union with the base 11, advantageously semi-cylindrical with the axis of the semi-cylinder perpendicular to the main axis. This bend 29 thus generates a "preferred rotation axis" for the flange 21.
    Advantageously, the flange 21 is connected to the base 11 through a joint area 30 having a width, measured perpendicular to the main axis, greater than or equal to 2 mm, preferably greater than or equal to 2.3 mm and most preferably between 2.3 and 3 mm. Indeed, this width helps increase the flexible properties of the flange and facilitates the use of less flexible materials, such as iron or iron-based alloys. In this sense, it is also advantageous that there is a gap between the flange 21 and the base 11, in particular between the lateral sections of the flange 21 and those of the elongated hole 17, since so! any possible contact between the flange 21 and the base 11 is avoided. This possible contact could cause friction forces that go against the elastic forces of the flange 21, hindering the elastic movement of the flange 21.
    The extensions 15 may have two preferred configurations. In one of them, each extension 15 has a semi-cylindrical shape, where the axis of the semi-cylinder is parallel to the axis of insertion. In the other, each extension 15 comprises a flat section 31 parallel to the base 11. This last alternative is the one shown in Figs.
    In the event that each extension 15 comprises a flat section 31, parallel to the base 11, the flat section 31 is connected to the corresponding side wall 13 preferably through two connecting bridges 33 arranged at the front and rear end of the flat section 31. In this way, between both joining bridges 33 there is a groove 35 that separates the central part of the flat section 31 from the corresponding side wall 13. Preferably, each flat section 31 comprises a projection 37 protruding from the underside of the flat section 31 extending towards the housing 3. In this way it is possible to give greater flexibility to the flat section 31 which improves the quality of the electrical contact between the head of insert 59 of the male terminal and the female terminal. In an advantageous alternative, each projection 37 comprises a flat central part 39, parallel to the base 11, where the flat central part 39 has a second projection 41 protruding from the lower face of the flat central part 39 extending towards the housing 3. This last alternative allows a smoother insert. This last alternative is

    the one shown in the embodiment of Figs. 8 to 10, which is otherwise equal to the embodiment of Figs. 1 to 7
    Advantageously, at least one of the extensions 15, and preferably both, includes a fixing hole 43 in its upper part. As will be seen below, these fixing holes 43 serve to fix the female terminal inside the corresponding plastic material connector.
    In Figs. 11 and 12 a thermoplastic material connector according to the invention is shown. The thermoplastic material connector has a through hole that defines a large inner cavity 45 suitable for housing the female terminal according to the invention. The inner cavity 45 has an anterior part 47 and a rear part 49, of greater height than the anterior part 47. Between them there is an inclined wall 51. In the anterior part 47 there are two fixing projections 53 extending towards the interior of the front part 47. The fixing projections 53 have a vertical anterior wall 55 and an inclined rear wall 57. The fixing projections 53 are suitable for being housed in the corresponding fixing holes 43 arranged in the extensions 15 of the female terminal. By inserting the female terminal through the rear part 49 of the thermoplastic material connector, the inclined rear walls 57 facilitate the insertion of the female terminal until the fixing projections 53 are housed inside the fixing holes 43. However, the walls previous 55 verticals prevent the female terminal from the thermoplastic material connector. That is, the fixation projections 53 make up an irreversible enclosure system. The fixing projections 53 are preferably of shorter length, measured in the direction of the insertion axis, than the length of the corresponding fixing holes 43. In this way, it allows a certain movement in the direction of the insertion axis of the female terminal with respect to the thermoplastic material connector. This relative movement serves to activate the decoupling system of the male terminal with respect to the female terminal. Indeed, as seen in Figs. 13 to 15, in the mounted position the insertion head 59 of the male terminal is in the housing 3 of the female terminal and the retention one 27 is housed in the corresponding hole 61 of the insertion head 59. When trying to separate the male terminal from the female terminal, the connector of thermoplastic material moves backwards with respect to the female terminal until the inclined wall 51 meets the head 23 of the flange 21. The inclined wall 51 pushes the head 23 backwards, forcing it to rotate downwards. In this way the holding one 27 leaves the hole 61 of the insertion head 59 and the male terminal is unlocked. Thanks to the fact that the head 23 has limited travel because it runs into the narrow passage 19, it is avoided to bend the flange 21 excessively, beyond its elastic limit.
