Conector de enchufe rapido de tubos flexibles.Quick connector of flexible tubes.
Campo tecnico de la invencionTechnical field of the invention
El objeto de la invencion es un conector de enchufe rapido del tipo de los que se utilizan para unir tubos flexibles de conductos de agua sanitaria o de calefaccion.The object of the invention is a quick plug connector of the type used to connect flexible pipes of sanitary or heating water conduits.
Antecedentes de la invencionBackground of the invention
Son conocidos y estan ampliamente difundidos en el mercado los conectores de enchufe rapido de tubos flexibles, tales como tubos flexibles compuestos de una capa interna de material plastico, una capa intermedia que contiene un componente metalico para dar resistencia al tubo y una capa externa tambien de material plasticos.Rapid plug connectors of flexible tubes, such as flexible tubes composed of an inner layer of plastic material, an intermediate layer containing a metal component to give resistance to the tube and an outer layer also of plastic material
Estos conectores estan disenados para recibir y conectar al menos un tubo flexible, que serla la version mas simple, aunque su diseno abarca la union de tubos en llnea o coaxialmente, a 90°, en T y otras opciones.These connectors are designed to receive and connect at least one flexible tube, which would be the simplest version, although its design covers the union of tubes in line or coaxially, at 90 °, in T and other options.
Entre la variedad de conectores de enchufe rapido que se conocen destacan los que estan constituidos por una pieza base de laton o material plastico apropiado que, como antes se indicaba, puede ser simple, doble, triple, etc., segun el numero y direction de los tubos que deban convergen en el mismo conector de enchufe rapido. Esta pieza base cuenta, al menos, con una tetina cubierta por un capuchon acoplado a la pieza base, de manera que entre la tetina y el capuchon se establece un espacio anular que puede recibir el extremo de un tubo flexible, para lo cual se introduce la tetina en el tubo flexible y ejerciendo una fuerza de empuje del tubo en contraposition de otra fuerza ejercida manual sobre el conector, se consigue el acoplamiento del tubo al conector.Among the variety of quick plug connectors that are known, those that are made up of a brass base piece or appropriate plastic material that, as indicated above, can be simple, double, triple, etc., according to the number and direction of the tubes that must converge in the same quick plug connector. This base piece has, at least, a nipple covered by a cap coupled to the base piece, so that an annular space is established between the nipple and the cap that can receive the end of a flexible tube, for which it is introduced the nipple in the flexible tube and exerting a pushing force of the tube in contrast to another force exerted manually on the connector, the coupling of the tube to the connector is achieved.
Es de destacar que esta familia de conectores cuenta, ademas, con un elemento retenedor del tubo. Dicho elemento esta constituido generalmente por un anillo metalico, que tiene una superficie plana de acoplamiento y una pluralidad de aletas o dientes radiales inclinados con respecto al plano del anillo, de tal manera que la inclination de los dientes en la direccion del acoplamiento no dificulta la penetration del tubo pero, una vez que este ha quedado introducido, su extraction resulta imposible por cuanto dichas aletas se clavan en la superficie exterior del tubo flexible que, como antes se ha indicado, es de material plastico.It is noteworthy that this family of connectors also has a tube retainer. Said element is generally constituted by a metal ring, which has a flat coupling surface and a plurality of radial fins or teeth inclined with respect to the plane of the ring, such that the inclination of the teeth in the direction of the coupling does not hinder the penetration of the tube but, once it has been introduced, its extraction is impossible because said fins are nailed to the outer surface of the flexible tube which, as previously indicated, is made of plastic material.
Ejemplos de este tipo de acoplamientos rapidos para tubos flexibles estan descritos en la EP 0550323, EP 1564473, EP 1642058 y NL 1019377. En estas Patentes pueden observarse soluciones que, partiendo de los elementos comunes anteriormente comentados, presentan realizaciones constructivas diferentes que conciernen a la pieza base, el manguito o capuchon, el sellado, retenedor y su sujecion en el conjunto, etc. En muchos de los casos el numero de piezas utilizado es elevado, lo cual repercute de forma importante en los costes de production y montaje.Examples of this type of quick couplings for flexible tubes are described in EP 0550323, EP 1564473, EP 1642058 and NL 1019377. In these patents, solutions can be observed which, starting from the common elements mentioned above, present different constructive embodiments concerning the base piece, sleeve or cap, seal, retainer and its fastener in the assembly, etc. In many cases the number of parts used is high, which has a significant impact on production and assembly costs.
Serla deseable, pues, contar con un conector conformado por un mlnimo numero de piezas, bien concebidas, y que su aplicacion y funcionamiento sea de la maxima sencillez y plenamente eficaz.It would be desirable, then, to have a connector consisting of a minimum number of pieces, well conceived, and that its application and operation be of maximum simplicity and fully effective.

dependeran del numero de conexiones que tengan que converger en el conector. Sobre el cuerpo de laton se acopla, al menos, un manguito o capuchon de manera que entre el cuerpo del conector y el capuchon se establece un alojamiento anular para recibir el extremo del tubo flexible que se quiere conectar. El capuchon esta constituido por dos cuerpos de material plastico unidos, por ejemplo, por tecnica de soldadura por ultrasonidos.they will depend on the number of connections that have to converge on the connector. At least one sleeve or cap is attached to the brass body so that an annular housing is established between the connector body and the cap to receive the end of the flexible tube to be connected. The cap is constituted by two bodies of plastic material joined, for example, by ultrasonic welding technique.
Una de las caracterlsticas de la invention es que el cuerpo del capuchon que queda al exterior, de forma sustancialmente troncoconica, es de material opaco y el cuerpo que queda al interior, sustancialmente cillndrico, tiene un grado de transparencia que permite visualizar el tubo flexible en la maniobra de su introduction en el conector, lo que permite al usuario conocer en todo momento la position del tubo en el conector y en especial si este ha alcanzado correctamente el tope de penetration.One of the characteristics of the invention is that the body of the cap that is outside, substantially truncated, is of opaque material and the body that is inside, substantially cylindrical, has a degree of transparency that allows viewing the flexible tube in the maneuver of its introduction in the connector, which allows the user to know at all times the position of the tube in the connector and especially if it has correctly reached the penetration stop.
Otra caracterlstica de la invencion es que el capuchon tiene una forma ergonomica, para facilitar el acoplamiento del conector al tubo, forma que se concreta a que el cuerpo transparente cuenta con una amplia extension cillndrica que, en la zona de acoplamiento forma un escalon, sobre el cual se puede empujar con el dedo pulgar en la maniobra de introduccion del tubo en el acoplamiento. Esta forma ergonomica evita que los dedos se desplacen en el momento en que se esta ejerciendo la presion, lo que es habitual en otros disenos cuyo capuchon es liso en el exterior.Another feature of the invention is that the cap has an ergonomic shape, to facilitate the coupling of the connector to the tube, so that the transparent body has a wide cylindrical extension that, in the coupling area forms a step, over which can be pushed with the thumb in the maneuver of introducing the tube into the coupling. This ergonomic shape prevents the fingers from moving at the time the pressure is being exerted, which is common in other designs whose cap is smooth on the outside.
Previamente a la union de los dos cuerpos que conforman el capuchon, se situa entre ambos el retenedor, constituido por un anillo metalico dotado de aletas radiales a modo de diente, cuyas aletas se encuentran plegadas hacia el interior del acoplamiento de manera que las citadas aletas flexan en la direction de acoplamiento permitiendo la introduccion del tubo flexible pero, una vez introducido este, resulta imposible su extraction por cuanto las aletas se clavan en la superficie exterior del tubo. A tales efectos, esto es, para la mayor eficacia de las aletas estas presentan un borde de ataque curvo que determina protuberancias extremas de enclavamiento.Prior to the union of the two bodies that make up the cap, the retainer is placed between both, consisting of a metal ring provided with radial fins as a tooth, whose fins are folded into the coupling so that the aforementioned fins They flex in the direction of coupling allowing the introduction of the flexible tube but, once introduced, it is impossible to extract because the fins are stuck in the outer surface of the tube. For this purpose, that is, for the greater efficiency of the fins they have a curved leading edge that determines extreme interlocking protuberances.
Para el correcto guiado y acoplamiento de los dos cuerpos de material plastico que conforman el capuchon, se ha previsto un machihembrado en la citada zona de acoplamiento, de tal manera que una vez acopladas se establece un hueco anular en el que queda alojado el anillo retenedor, anillo que presenta una section curva, de manera que la llnea curva del retenedor con la cooperation de las aletas hace el efecto de muelle para mantenerlo en posicion operativa, pero con un cierto grado de libertad de movimientos, para que las aletas puedan flexar y para que el retenedor pueda tener un cierto movimiento de giro dentro de su alojamiento. En la posicion de partida, esto es, antes de la introduccion del tubo flexible, las aletas descansan sobre un labio conico interior del cuerpo opaco que conforma el capuchon.For the correct guidance and coupling of the two bodies of plastic material that make up the cap, a tongue and groove is provided in the aforementioned coupling area, so that once coupled an annular hole is established in which the retaining ring is housed , a ring that has a curved section, so that the curved line of the retainer with the cooperation of the fins makes the spring effect to keep it in operational position, but with a certain degree of freedom of movement, so that the fins can flex and so that the retainer can have a certain turning movement inside its housing. In the starting position, that is, before the introduction of the flexible tube, the fins rest on an inner conical lip of the opaque body that forms the cap.
La pieza base de laton presenta, al menos, un cuello para el acoplamiento a presion del cuerpo transparente del capuchon, cuello que esta definido entre sendos resaltes anulares, uno de los cuales cuenta con una seccion inclinada para facilitar el acoplamiento del cuerpo del capuchon citado, el cual cuenta con un reborde periferico interior apropiado al efecto.The brass base piece has at least one neck for the snap-on coupling of the transparent body of the cap, which is defined between two annular projections, one of which has an inclined section to facilitate the coupling of the aforementioned cap body , which has an inner peripheral flange appropriate for this purpose.
El otro extremo de la pieza base de laton conforma la tetina que ha de introducirse por la boca del tubo flexible. Proximo a su extremo, la tetina cuenta con un rebaje que conforma una cajonera para el montaje de la junta de sellado o estanqueidad, la cual cuenta con una amplia base de apoyo en la cajonera, y una seccion triangular de tal manera que la altura del triangulo es menor que la base, de esta manera, al introducir la tetina en el tubo flexible, resulta practicamente imposible que esta maniobra desplace la tetina fuera de su alojamiento, en cuyo supuesto perderla su funcion de estanqueidad.The other end of the brass base piece forms the nipple to be introduced through the mouth of the flexible tube. Near its end, the nipple has a recess that forms a chest of drawers for the assembly of the seal or seal, which has a wide base of support in the drawer, and a triangular section such that the height of the triangle is smaller than the base, in this way, when introducing the nipple into the flexible tube, it is practically impossible for this maneuver to move the nipple out of its housing, in which case it will lose its sealing function.
A continuation de la junta de sellado la tetina continua con un tramo cillndrico para finalmente adoptar una forma conica, que tiene varios efectos beneficiosos en el funcionamiento delFollowing the sealing joint, the nipple continues with a cylindrical section to finally adopt a conical shape, which has several beneficial effects on the operation of the

Realizacion preferente de la invencionPreferred Embodiment of the Invention
A la vista de estas figuras puede verse como el conector (1) objeto de la invencion esta constituido por una pieza base (2) de laton o material plastico apropiado, sobre la que se monta por engarce a presion al menos un capuchon (3) que esta constituido por dos cuerpos (31) y (32) de material plastico unidos por soldadura por ultrasonidos u otra tecnica apropiada. El cuerpo (31), sustancialmente troncoconico es opaco, en tanto que el cuerpo (32), sustancialmente cillndrico, es transparente o tiene un grado de transparencia que permite visualizar el tubo flexible en la maniobra de su introduction en el conector, de tal manera que el usuario vea en todo momento la position del tubo (5) en el conector (1) y sepa cuando ha alcanzado la posicion tope.In view of these figures it can be seen how the connector (1) object of the invention is constituted by a base piece (2) of brass or appropriate plastic material, on which it is mounted by crimping at least one cap (3) which consists of two bodies (31) and (32) of plastic material joined by ultrasonic welding or other appropriate technique. The substantially truncated cone body (31) is opaque, while the substantially cylindrical body (32) is transparent or has a degree of transparency that allows the flexible tube to be visualized in the maneuver of its introduction into the connector, in such a way that the user always sees the position of the tube (5) in the connector (1) and knows when he has reached the top position.
El cuerpo (32), del capuchon (3), presenta un escalon (322) en la zona de union al cuerpo (31). La amplia y sustancial forma general cillndrica del cuerpo (32) y el escalon (322) conforman una superficie de agarre ergonomica para el usuario, que le permite manipular con los dedos comodamente el conector (1) para acoplarlo al tubo flexible (5), sirviendo el escalon (322) como zona de empuje. El acoplamiento se realiza agarrando con una mano o con un util apropiado el tubo y con la otra el conector (1) y ejerciendo fuerzas opuestas.The body (32), of the cap (3), has a step (322) in the area of attachment to the body (31). The wide and substantial general cylindrical shape of the body (32) and the step (322) form an ergonomic grip surface for the user, which allows him to comfortably manipulate the connector (1) with fingers to attach it to the flexible tube (5), serving the step (322) as a push zone. The coupling is made by grasping the tube with one hand or with an appropriate tool and with the other the connector (1) and exerting opposite forces.

La pieza base (2) cuenta con, al menos, una garganta (22) definida entre dos resaltes perimetrales, para el acoplamiento del cuerpo (32) el cual presenta en su boca un reborde interior (321) apropiado para su montaje y fijacion de las partes acopladas.The base piece (2) has, at least, a throat (22) defined between two perimeter projections, for the coupling of the body (32) which has in its mouth an inner flange (321) suitable for its assembly and fixing of the coupled parts.
Asimismo, la pieza base (2) conforma al menos una tetina introducible por la boca del tubo flexible (5). Proximo al extremo de dicha tetina se ha previsto un cajeado (23) para la ubicacion de una junta de sellado o estanqueidad (4). Dicho cajeado presenta mucha superficie de contacto y poca altura, al igual que la junta (4), que cuenta con una gran superficie de apoyo sobre el cajeado (23) y escasa altura. Puede decirse que la altura de la junta es del orden de la mitad de la anchura del cajeado (23). La junta (4) tiene un labio de contacto de seccion triangular. Con una amplia base de apoyo en el cajeado (23) de la tetina. Este diseno de la junta, como se ha indicado, hace materialmente imposible que al introducir la tetina en el tubo (5) la junta de sellado (4) pueda salir de su alojamiento, lo que suele suceder frecuentemente en aquellos conectores que emplean juntas toricas convencionales. Asimismo, el labio de contacto en forma de triangulo equilatero muy abierto, facilita la introduction del tubo flexible (5). La simetrla de la junta facilita el ensamblado de la misma en instalaciones de montaje automatizadas.Likewise, the base piece (2) forms at least one nipple that can be introduced through the mouth of the flexible tube (5). Near the end of said nipple, a recess (23) is provided for the location of a seal or seal (4). Said recess has a large contact surface and low height, as does the joint (4), which has a large support surface on the recess (23) and a low height. It can be said that the height of the joint is of the order of half the width of the recess (23). The gasket (4) has a triangular section contact lip. With a broad base of support in the cajeado (23) of the nipple. This design of the gasket, as indicated, makes it materially impossible that when the nipple is introduced into the tube (5) the sealing gasket (4) can leave its housing, which usually happens in those connectors that use toric gaskets. conventional. Likewise, the contact lip in the shape of a very open equilateral triangle facilitates the introduction of the flexible tube (5). The symmetry of the joint facilitates its assembly in automated assembly facilities.
Una vez montado el capuchon (3) sobre la pieza base (2), se conforma entre ambos un hueco anular (6) dimensionado para recibir el extremo del tubo flexible (5), tal y como se observa en la figura 3.Once the cap (3) is mounted on the base piece (2), an annular recess (6) sized to receive the end of the flexible tube (5) is formed between them, as shown in Figure 3.
La introduccion de la tetina en el tubo flexible (5) se ve favorecida por la especial geometrla de dicha tetina, que cuenta con una zona inicial sustancialmente cillndrica, que en la parte final (24) adopta una forma conica, tal y como puede observarse en la figura 7. Este diseno, ademas de favorecer la introduccion de la tetina en el tubo, mejora la estanqueidad entre el conector cuando la union de este con el tubo esta sometida a tensiones y esfuerzos de flexion.The introduction of the nipple into the flexible tube (5) is favored by the special geometry of said nipple, which has a substantially cylindrical initial zone, which in the final part (24) adopts a conical shape, as can be seen in figure 7. This design, in addition to favoring the introduction of the nipple in the tube, improves the tightness between the connector when the union of this with the tube is subjected to stresses and flexural stresses.
El anillo retenedor (8) cuenta con una parte anular de seccion curva (81) y unas aletas radiales (82). La parte anular (81) queda alojada en un hueco (7) que se forma al unir los cuerpos (31) y (32). De esta parte anular (81) nacen una pluralidad de aletas radiales (82), inclinadas hacia la parte interna del conector (1). Tales aletas, en position no operante, descansan sobre un labio interior (310) del cuerpo (31). La forma curva de la parte anular (81) del retenedor y el apoyo de las aletas (82) en el labio (310), cooperan a modo de muelle a los efectos de mantener el retenedor en posicion operativa y permiten que dicho retenedor pueda girar incluso en su alojamiento, lo cual puede resultar en ocasiones util para la mejor introduccion de la tetina en el tubo flexible.The retaining ring (8) has an annular part with a curved section (81) and radial fins (82). The annular part (81) is housed in a recess (7) formed by joining the bodies (31) and (32). From this annular part (81) a plurality of radial fins (82) are born, inclined towards the internal part of the connector (1). Such fins, in non-operative position, rest on an inner lip (310) of the body (31). The curved shape of the annular part (81) of the retainer and the support of the fins (82) on the lip (310) cooperate as a spring in order to keep the retainer in operative position and allow said retainer to rotate even in its housing, which can sometimes be useful for the best introduction of the nipple into the flexible tube.
Las aletas (82) tienen una inclination que permite la introduccion facil de la tetina en el tubo pero, una vez introducido este, hacen materialmente imposible su extraction porque tienen un borde de ataque que produce que se clave facilmente en la superficie externa del tubo evitando su extraccion.The fins (82) have an inclination that allows the easy introduction of the nipple into the tube but, once this is introduced, they make material extraction impossible because they have an leading edge that causes them to easily key into the outer surface of the tube avoiding its extraction.
