La presente invención consiste conforme indica su enunciado en un "PROCEDIMIENTO DE INYECCIÓN DE PASACABLES Y ELEMENTO CENTRADOR/SEPARADOR PARA UTILIZARLO CON DICHO PROCEDIMIENTO", cuyas nuevas características de construcción, conformación y diseño cumplen la misión para la cual han sido específicamente proyectados, con una seguridad y eficacia máximas y proporcionando numerosas ventajas tal como se detallará en la presente memoria.The present invention consists in accordance with its statement in a "PASSENGER INJECTION PROCEDURE AND CENTRATOR / SEPARATOR ELEMENT TO USE IT WITH SUCH PROCEDURE", whose new construction, conformation and design characteristics fulfill the mission for which they have been specifically projected, with a maximum safety and efficiency and providing numerous advantages as detailed herein.
La instalación eléctrica de un vehículo implica que por diversas partes del mismo deben discurrir gran cantidad de cables eléctricos, los cuales se agrupan en mazos. Dichos cables deben discurrir a través de paredes y demás elementos del vehículo, motivo por el cual se utilizan pasacables. Los pasacables consisten en una zona del mazo de cables en la que se ha inyectado un material plástico aislante que corresponde a la zona del mazo de cables que atraviesa una pared del vehículo o cualquier parte del mismo que se interponga en la trayectoria del mazo de cables.The electrical installation of a vehicle implies that a large number of electrical cables must run through various parts of the vehicle, which are grouped into mallets. These cables must run through walls and other elements of the vehicle, which is why cable glands are used. The cable glands consist of an area of the cable harness in which an insulating plastic material has been injected that corresponds to the area of the cable harness that crosses a vehicle wall or any part thereof that interposes in the cable harness path .
El mazo de cables es sometido al moldeo por inyección de un material plástico que se introduce por entre los cables eléctricos quedando aislados de cualquier elemento exterior. Sin embargo, la práctica de esta técnica de inyección para la formación de pasacables presenta diversos inconvenientes. Uno de dichos inconvenientes es que el mazo de cables queda descentrado respecto a la masa plástica inyectada. En efecto, un corte transversal de un pasacables obtenido mediante un procedimiento de inyección convencional permite observar que el mazo de cables no se encuentra en una posición centrada, concéntrico al material inyectado. Consecuentemente, el espesor del pasacables obtenido no es homogéneo en toda la periferia del mazo de cables, presentando zonas de mayor espesor que otras. En ciertos casos, el espesor puede llegar a ser tan reducidoThe cable harness is subjected to injection molding of a plastic material that is introduced between the electric cables being isolated from any external element. However, the practice of this injection technique for the formation of cable glands presents several drawbacks. One of these drawbacks is that the harness is offset from the injected plastic mass. Indeed, a cross-section of a cable gland obtained by a conventional injection procedure makes it possible to observe that the cable harness is not in a centered position, concentric to the injected material. Consequently, the thickness of the cable gland obtained is not homogeneous throughout the periphery of the cable harness, presenting areas of greater thickness than others. In certain cases, the thickness can become so reduced
HOJA DE SUSTITUCIÓN (REGLA 26) que algunos cables pueden quedar al descubierto y, por lo tanto, las condiciones de estanqueidad requeridas no se cumplen obteniéndose un pasacables poco seguro. Otro inconveniente derivado de la técnica de inyección convencional para la formación de pasacables es que para garantizar unas condiciones mínimas de estanqueidad debe utilizarse una gran cantidad de material plástico de inyección con el fin de proporcionar un pasacables con un grosor relativamente grande para asegurar la estanqueidad del conjunto.SUBSTITUTE SHEET (RULE 26) that some cables may be exposed and, therefore, the required sealing conditions are not met, obtaining an unsecured cable gland. Another drawback derived from the conventional injection technique for the formation of cable glands is that in order to guarantee minimum sealing conditions a large amount of plastic injection material must be used in order to provide a cable gland with a relatively large thickness to ensure the sealing of the set.
La presente invención se ha desarrollado con el fin de solucionar todos los inconvenientes que presentan los procedimientos de inyección de pasacables convencionales y modifica el estado de la técnica anteriormente citado de manera que se consiguen los objetivos pretendidos. La invención se refiere también a un elemento centrador/separador para utilizarlo con el procedimiento que se describe a continuación.The present invention has been developed in order to solve all the inconveniences of conventional cable gland injection procedures and modifies the state of the art mentioned above so that the intended objectives are achieved. The invention also relates to a centering / separating element for use with the procedure described below.
Como se ha indicado anteriormente, el procedimiento de la invención se basa en un procedimiento convencional de inyección de un material plástico sobre un mazo de cables conductores que forman parte, por ejemplo, de la instalación eléctrica de un vehículo. En lineas generales, el procedimiento comprende las etapas de fluidificación del material plástico e inyección de dicho material en un molde sobre el mazo de cables. La particularidad del procedimiento que se describe reside en que éste incluye, además, la etapa de incorporar un elemento centrador/separador sobre el mazo de cables rodeándolo para ofrecer un espesor minimo y una distribución homogénea del material inyectado. Dicho elemento centrador/separador se aplica al mazo de cables antes de inyectar el material plástico y queda posteriormente fijado al mismo.As indicated above, the process of the invention is based on a conventional method of injecting a plastic material onto a harness of conductive cables that are part, for example, of the electrical installation of a vehicle. In general, the process comprises the stages of fluidization of the plastic material and injection of said material into a mold on the cable harness. The particularity of the procedure described is that it also includes the step of incorporating a centering / separating element on the cable harness surrounding it to offer a minimum thickness and a homogeneous distribution of the injected material. Said centering / separating element is applied to the harness before injecting the plastic material and is subsequently fixed thereto.
Gracias a la incorporación de este elemento centrador/separador, el cual queda permanentemente aplicado en el mazo de cables tras el proceso de inyección, se obtiene un pasacables con un espesor de pared minimo que garantiza las condiciones de estanqueidad necesarias en la instalación eléctrica. Esta ventaja está asociada con un ahorro considerable de material de inyección, lo cual influye favorablemente en el coste total de producción. Además, el resultado obtenido ofrece un elevado grado de calidad puesto que el mazo de cables queda perfectamente centrado en el pasacables y, por lo tanto, el material de inyección se distribuye homogéneamente en la periferia del mismo .Thanks to the incorporation of this centering / separating element, which is permanently applied In the cable harness after the injection process, a cable gland with a minimum wall thickness is obtained that guarantees the necessary sealing conditions in the electrical installation. This advantage is associated with a considerable saving of injection material, which favorably influences the total production cost. In addition, the result obtained offers a high degree of quality since the cable harness is perfectly centered on the cable gland and, therefore, the injection material is distributed homogeneously on the periphery thereof.
El elemento centrador/separador utilizado en el procedimiento de inyección descrito anteriormente está configurado por dos semiaros de plástico que están unidos entre si por un extremo. La zona de unión, es decir, el extremo común de los citados semiaros, es una zona de sección reducida que permite el movimiento de un semiaro respecto al otro con el fin de cerrar el conjunto rodeando el mazo de cables que va a ser inyectado posteriormente para formar el pasacables. Dicho elemento centrador/separador incluye medios de cierre regulables de dichos semiaros entre si que consisten en un diente interior formado en el extremo libre de un semiaro, el cual está diseñado convenientemente para que encaje en cualquiera de los resaltes exteriores de una superficie escalonada del otro semiaro. Esto permite ventajosamente regular el diámetro interior del elemento centrador/separador de acuerdo con el número de cables del mazo de cables. De este modo, el elemento centrador/separador presenta un carácter universal, de manera que un único tipo de elemento centrador/separador sirve para mazos de cables formados por un número de cables distinto .The centering / separating element used in the injection procedure described above is configured by two plastic semiaros that are joined together by one end. The junction zone, that is to say, the common end of the aforementioned semiaros, is a zone of reduced section that allows the movement of a semiaro with respect to the other in order to close the assembly surrounding the harness of cables that will be injected later to form the cable gland. Said centering / separating element includes adjustable closing means of said semiaros among themselves consisting of an inner tooth formed at the free end of a semiaro, which is conveniently designed to fit into any of the outer projections of a stepped surface of the other. semi. This advantageously allows the internal diameter of the centering / separating element to be adjusted according to the number of cables in the cable harness. Thus, the centering / separating element has a universal character, so that a single type of centering / separating element is used for cable harnesses formed by a different number of cables.
Por otra parte, cada semiaro está provisto de una pluralidad de tetones que sobresalen hacia fuera, los cuales están destinados a retener el elemento centrador/separador en posición respecto al mazo de cables. Cada tetón presenta una configuración substancialmente cilindrica con un acabado esférico en su parte extrema. Dicha parte extrema es la zona de contacto con la pared de la cavidad del molde, asegurando, de este modo, el centraje del mazo de cables a inyectar. Estos tetones permiten el paso del material de inyección hacia los cables y, de este modo, posibilitan que el elemento centrador/separador quede totalmente cubierto con dicho material de inyección. Por otra parte, cada semiaro del elemento centrador/separador de la invención esté provisto interiormente de una aleta flexible que actúa sobre los cables presionándolos cuando dichos semiaros se cierran mutuamente sobre el mazo de cables. Se obtiene pues un elemento centrador/separador con el cual se consiguen solventar los inconvenientes derivados de la técnica de inyección convencional. Con dicho elemento centrador/separador se mantiene el centrado de los cables del mazo de cables durante el proceso de inyección permitiento asegurar un espesor minimo de material inyectado entre cada cable y el exterior del pasacables inyectado.On the other hand, each semiaro is provided with a plurality of studs protruding outwards, which are intended to retain the centering / separating element in position relative to the harness. Each stud has a substantially cylindrical configuration with a spherical finish at its end. Said end part is the contact area with the wall of the mold cavity, thus ensuring the centering of the harness to be injected. These lugs allow the passage of the injection material towards the cables and, thus, allow the centering / separator element to be fully covered with said injection material. On the other hand, each semiaro of the centering / separating element of the invention is internally provided with a flexible flap that acts on the cables by pressing them when said semiaros close to each other on the harness. A centering / separating element is thus obtained with which the inconveniences derived from the conventional injection technique are solved. With said centering / separating element, the centering of the cables in the cable harness is maintained during the injection process, allowing to ensure a minimum thickness of injected material between each cable and the outside of the injected cable gland.
Las características y las ventajas del procedimiento de inyección de pasacables y del elemento centrador/separador para utilizarlo con dicho procedimiento resultarán evidentes a partir de la descripción detallada de una realización preferida de la misma que se dará, de aqui en adelante, a modo de ejemplo no limitativo, con referencia a los dibujos que se acompañan, en los cuales:The characteristics and advantages of the cable gland injection procedure and the centering / separating element for use with said procedure will be apparent from the detailed description of a preferred embodiment thereof, which will be given hereinafter, by way of example. non-limiting, with reference to the accompanying drawings, in which:
