Description detallada de unas formas de realizacion de la invencionDetailed description of some embodiments of the invention
En las Figs. 1 a 7 se muestra una primera forma de realizacion de un terminal hembra de acuerdo con la invencion. El terminal hembra esta fabricado a partir de una lamina de material metalico troquelada y doblada. El terminal hembra tiene una parte anterior 1 que presenta un alojamiento 3 y una abertura 5 por la que puede ser introducido el cabezal de insertion 59 de un terminal macho substancialmente aplanado (ver Figs. 13 a 15). El movimiento de insercion del cabezal de insercion 59 en el alojamiento 3 define un eje de insercion o eje longitudinal del terminal hembra.

La parte anterior 1 comprende una base 11 que limita el alojamiento 3 por su parte inferior, dos paredes laterales 13, una a cada lado del eje de insercion, que se extienden paralelas al eje de insercion y que tienen su origen en los extremos laterales de la base 11. Las paredes laterales 13 se extienden hacia arriba, formando un angulo recto con la base. Las paredes laterales 13 limitan lateralmente el alojamiento 3. Cada pared lateral 13 tiene, en su extremo superior, una prolongation 15 que se proyecta hacia el eje de insercion y que delimita, al menos parcialmente, el alojamiento 3 por su parte superior.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.
La base 11 presenta un orificio alargado 17 que define un eje principal paralelo al eje de insercion. El orificio alargado 17 presenta un paso estrecho 19 de anchura, medida en sentido perpendicular al eje longitudinal, menor que el extremo posterior que el orificio alargado 17. Del extremo anterior del orificio alargado 17 se proyecta una pestana 21 hacia atras en sentido del eje principal. La pestana 21 esta hecha del material original de la lamina metalica que estaba en el lugar donde se ha realizado el orificio alargado 17, lo que permite ahorrar material. La pestana 21 presenta una cabeza 23 en el extremo posterior de la pestana 21. La cabeza 23 esta unida al resto de la pestana 21 a traves de un cuello 25 donde el cuello 25 tiene una anchura, medida en sentido perpendicular en sentido longitudinal, menor que la cabeza 23. El cuello 25 se corresponde con el paso estrecho 19 del orificio alargado 17. La pestana 21 esta doblada hacia arriba en un tramo anterior al cuello 25 de manera que la cabeza 23 queda sobre la vertical del paso estrecho 19 del orificio alargado 17. El extremo superior de la cabeza 23 esta doblado hacia atras.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.
La pestana 21 presenta una una de retention 27 que se proyecta hacia el alojamiento 3. Esta una de retencion 27 es la que se alojara en un orificio 61 dispuesto en el cabezal de insercion 59 del terminal macho haciendo asl la funcion de encliquetado. Para desencliquetar el terminal macho es suficiente con apretar la pestana 21 hacia debajo de manera que la una de retencion 27 sale del orificio 61 previsto en el terminal macho permitiendo asl su extraction.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.
Este terminal hembra de acuerdo con la invention presenta una pestana 21 con una gran flexibilidad. La pestana 21 esta unida directamente a la base 11 y, ademas, esta unida a la base 11 por ambos lados de la pestana 21. Adicionalmente, el posicionado de la cabeza 23 por encima del paso estrecho 19 hace que en ningun momento se pueda doblar la pestana 21 hacia abajo una cantidad indiscriminada, ya que la cabeza 23 (cuya anchura es mayor que la anchura del paso estrecho (19)) topara con los bordes del paso estrecho 19. De esta manera se limita el recorrido de flexado de la pestana 21. Todo ello permite ofrecer un terminal hembra con un sistema de encliquetado ampliamente fiable, que no puede ser doblado mas alla de su llmite elastico por lo que siempre conserva sus propiedades elasticas y que puede ser realizado deThis 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

materiales menos flexibles que los usualmente empleados. En particular puede ser realizado de hierro y/o de aleaciones de base hierro. Se entiende por aleaciones de base hierro aquellas en las que su componente mayoritario es hierro.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.
Preferentemente la pestana 21 tiene una doblez 29 en la zona de union con la base 11, ventajosamente de forma semicillndrica con el eje del semicilindro perpendicular al eje principal. Esta doblez 29 genera asi un "eje de rotacion preferente” para la pestana 21.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.
Ventajosamente la pestana 21 esta unida a la base 11 a traves de una zona de union 30 que tiene una anchura, medida en sentido perpendicular al eje principal, mayor o igual que 2 mm, preferentemente mayor o igual que 2,3 mm y muy preferentemente entre 2,3 y 3 mm. Efectivamente, esta anchura colabora a incrementar las propiedades flexibles de la pestana y facilita el hecho de emplear materiales menos flexibles, como el hierro o las aleaciones de base hierro. En este sentido tambien es ventajoso que entre la pestana 21 y la base 11 haya una holgura, en particular ente los tramos laterales de la pestana 21 y los del orificio alargado 17, ya que as! se evita cualquier posible contacto entre la pestana 21 y la base 11. Este posible contacto podrla provocar unas fuerzas de rozamiento que irlan en contra de las fuerzas elasticas de la pestana 21, dificultando el movimiento elastico de la pestana 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.
Las prolongaciones 15 pueden presentar dos configuraciones preferentes. En una de ellas cada prolongacion 15 presenta una forma semicillndrica, donde el eje del semicilindro es paralelo al eje de insercion. En la otra, cada prolongacion 15 comprende un tramo plano 31 paralelo a la base 11. Esta ultima alternativa es la que se muestra en las Figs.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.
En el caso que cada prolongacion 15 comprenda un tramo plano 31, paralelo a la base 11, el tramo plano 31 esta unido a la pared lateral 13 correspondiente preferentemente a traves de dos puentes de union 33 dispuestos en el extremo anterior y posterior del tramo plano 31. De esta manera, entre ambos puentes de union 33 queda una ranura 35 que separa la parte central del tramo plano 31 de la pared lateral 13 correspondiente. Preferentemente cada tramo plano 31 comprende una proyeccion 37 que sobresale de la cara inferior del tramo plano 31 extendiendose hacia el alojamiento 3. De esta manera se consigue dar una mayor flexibilidad al tramo plano 31 lo que mejora la calidad del contacto electrico entre el cabezal de insercion 59 del terminal macho y el terminal hembra. En una alternativa ventajosa, cada proyeccion 37 comprende una parte central plana 39, paralela a la base 11, donde la parte central plana 39 presenta una segunda proyeccion 41 que sobresale de la cara inferior de la parte central plana 39 extendiendose hacia el alojamiento 3. Esta ultima alternativa permite una insercion mas suave. Esta ultima alternativa esIn 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

Ventajosamente por lo menos una de las prolongaciones 15, y preferentemente ambas, incluye un orificio de fijacion 43 en su parte superior. Como se vera a continuation estos orificios de fijacion 43 sirven para la fijacion del terminal hembra en el interior del conector de material plastico correspondiente.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.
En las Figs. 11 y 12 se muestra un conector de material termoplastico de acuerdo con la invention. El conector de material termoplastico presenta un orificio pasante que define una gran cavidad interior 45 apta para alojar el terminal hembra de acuerdo con la invencion. La cavidad interior 45 presenta una parte anterior 47 y una parte posterior 49, de mayor altura que la parte anterior 47. Entre ambas hay una pared inclinada 51. En la parte anterior 47 hay dos proyecciones de fijacion 53 que se extienden hacia el interior de la parte anterior 47. Las proyecciones de fijacion 53 tienen una pared anterior 55 vertical y una pared posterior 57 inclinada. Las proyecciones de fijacion 53 son aptas para alojarse en los orificios de fijacion 43 correspondientes dispuestos en las prolongaciones 15 del terminal hembra. Al insertar el terminal hembra por la parte posterior 49 del conector de material termoplastico, las paredes posteriores 57 inclinadas facilitan la insertion del terminal hembra hasta que las proyecciones de fijacion 53 quedan alojadas en el interior de los orificios de fijacion 43. Sin embargo las paredes anteriores 55 verticales impiden que se puedan sacar el terminal hembra del conector de material termoplastico. Es decir, las proyecciones de fijacion 53 conforman un sistema de encliquetado irreversible. Las proyecciones de fijacion 53 son preferentemente de menor longitud, medida en sentido del eje de insercion, que la longitud de los orificios de fijacion 43 correspondientes. De esta manera ser permite un cierto movimiento en sentido del eje de insercion del terminal hembra respecto del conector de material termoplastico. Este movimiento relativo sirve para activar el sistema de desencliquetado del terminal macho respecto del terminal hembra. Efectivamente, tal como se ve en las Figs. 13 a 15, en la position montada el cabezal de insercion 59 del terminal macho esta en el alojamiento 3 del terminal hembra y la una de retention 27 esta alojada en el orificio 61 correspondiente del cabezal de insercion 59. Al intentar separar el terminal macho del terminal hembra, el conector de material termoplastico se mueve hacia atras respecto del terminal hembra hasta que la pared inclinada 51 topa con la cabeza 23 de la pestana 21. La pared inclinada 51 empuja la cabeza 23 hacia atras, obligandola a rotar hacia abajo. De esta manera la una de retencion 27 sale del orificio 61 del cabezal de insercion 59 y se desbloquea el terminal macho. Gracias a que la cabeza 23 tiene limitado su recorrido debido a que topa con el paso estrecho 19, se evita doblar excesivamente la pestana 21, mas alla de su llmite elastico.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.
