OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un borne de conexión bidireccional sin tornillos, que está previsto para permitir la conexión en correspondencia con la parte superior del considerado borne así como en correspondencia con la parte lateral del mismo, indistintamente, adaptándose así a las diferentes formas que de acuerdo con los países realizan el conexionado de cables.The present invention relates to a bi-directional connection terminal without screws, which is intended to allow connection in correspondence with the top part of the terminal considered as well as in correspondence with the side part thereof, interchangeably, thus adapting to the different shapes that according to the countries they perform the connection of cables.
El objeto de la invención es satisfacer la dualidad de mercados, en base a que el borne de conexión sin tornillos de la invención está materializado de manera tal que permite el conexionado del cable desde dos direcciones u orientaciones diferentes.The object of the invention is to satisfy the duality of markets, based on the fact that the screwless connection terminal of the invention is materialized in such a way that it allows the cable to be connected from two different directions or orientations.
ANTECEDENTESDELAINVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, la fijación de los conductores eléctricos en los bornes de conexión, en cualquiera de sus aplicaciones prácticas posibles, se realiza mediante los denominados bornes con tornillos, consistentes éstos en una lámina que hace las funciones de contacto eléctrico a la que se incorpora un tornillo y una tuerca, arandela o elemento equivalente, que hace de elemento de fijación del cable, permitiendo la continuidad de la transmisión de corriente eléctrica. No obstante, en los últimos años se han venido desarrollando diferentes sistemas de borne de conexión con una característica común, cual es la eliminación del tornillo de fijación del cable al borne, sustituyéndolo por un elemento de presión que permite la fijación del cable y el correspondiente conexionado, con la simple introducción del mismo en un alojamiento creado al efecto. Este nuevo sistema, denominado "borne sin tornillo" ha facilitado sustancialmente la labor al profesional eléctrico.As is known, the fixing of the electrical conductors in the connection terminals, in any of its possible practical applications, is carried out by means of the so-called screw terminals, these consisting of a sheet that performs the functions of electrical contact to which it is incorporated a screw and a nut, washer or equivalent element, which acts as a cable fixing element, allowing the continuity of the transmission of electric current. However, in recent years different connection terminal systems have been developed with a common feature, which is the removal of the cable fixing screw to the terminal, replacing it with a pressure element that allows the cable fixing and the corresponding connected, with the simple introduction of it in an accommodation created for this purpose. This new system, called "screwless terminal" has substantially facilitated the work of the electrical professional.
Ahora bien, todos los fabricantes que han implementado en sus productos cualquiera de los dos sistemas de bornes, los han realizado de modo que la conexión de los cables a dichos bornes se realiza siempre en una única dirección; es decir, independientemente de la geometría de la pieza eléctrica, la conexión de los cables a los bornes se hace introduciéndolos por una única cara de la pieza, bien por la cara posterior o bien por una de las caras laterales de la propia pieza eléctrica.However, all the manufacturers that have implemented any of the two terminal systems in their products have made them so that the connection of the cables to these terminals is always carried out in a single direction; that is, regardless of the geometry of the electrical part, the connection of the cables to the terminals is made by introducing them by a single face of the piece, either by the rear face or by one of the side faces of the electrical part itself.
De esta manera, la elección de una u otra dirección de conexionado viene condicionada por el diseño de la pieza por parte del fabricante, o por la costumbre de uso de los diferentes países que prefieren una determinada dirección para la conexión del cable, sin otra justificación que la tradición, no aceptando tomas de corriente que tengan la conexión del cable en dirección diferente a la habitualmente utilizada en el país.In this way, the choice of one or another connection direction is conditioned by the design of the part by the manufacturer, or by the custom of use of the different countries that prefer a certain direction for the connection of the cable, without other justification that the tradition, not accepting sockets that have the connection of the cable in a different direction to the one usually used in the country.
Esas diferencias de uso y de mercado han obligado a los fabricantes que buscan alcanzar una importante penetración en todos los países, a crear series distintas de producto con entrada de cables diferentes para los distintos países, lo que implica un mayor coste de fabricación por multiplicidad de series para una misma aplicación por parte del usuario final del producto, el cual no percibe nunca la diferencia por la natural separación de mercado. No obstante, se conocen bornes previstos para llevar a cabo el conexionado de dos cables según dos direcciones diferentes, pudiendo citar la patente alemana DE 3122303 y la patente española ES 2195229, de manera que en el primer caso se describe un borne capaz de unir dos conductores que puedan ser introducidos en el terminal de conexión por dos direcciones diferentes, aunque basándose en disponer sobre un mismo soporte dos piezas elásticas tipo muelle, unidas por un elemento de conexión intermedio que las pone en contacto eléctrico, disposición ésta que sirve para unir dos conectores sin necesidad de tornillos ni soldaduras y para poner en contacto un conductor externo con un dispositivo eléctrico que tuviera dicho terminal de conexión.These differences in use and market have forced manufacturers seeking to achieve significant penetration in all countries, to create different product series with different cable entries for different countries, which implies a higher manufacturing cost due to the multiplicity of series for the same application by the end user of the product, which never perceives the difference due to the natural market separation. However, terminals intended to carry out the connection of two cables according to two different directions are known, the German patent DE 3122303 and the Spanish patent ES 2195229 being cited, so that in the first case a terminal capable of joining two conductors that can be introduced in the connection terminal by two different directions, although based on having on the same support two spring-type elastic parts, joined by an intermediate connection element that puts them in electrical contact, this arrangement that serves to join two connectors without the need for screws or welds and to connect an external conductor with an electrical device that had said connection terminal.
Ahora bien, en esta solución de borne bidireccional descrito en la comentada patente alemana DE 3122303, la duplicidad de los elementos elásticos para poder llevar a cabo el conexionado de dos cables en direcciones diferentes, supone un encarecimiento notable puesto que el soporte ha de estar realizado con unas características especiales para poder alojar y ubicar convenientemente los dos elementos elásticos que realizan el conexionado de dos cables en direcciones distintas.However, in this bidirectional terminal solution described in the commented German patent DE 3122303, the duplicity of the elastic elements to be able to carry out the connection of two cables in different directions, supposes a notable increase since the support has to be realized with special characteristics to be able to accommodate and conveniently locate the two elastic elements that make the connection of two cables in different directions.
Igualmente, en la patente española ES 2195229 se describe un borne que permite realizar el conexionado de dos cables en direcciones diferentes, aunque no en direcciones perpendiculares entre sí, de manera tal que este borne es enormemente complejo en lo que respecta al soporte base, como lo es el elemento elástico que ha de establecer la conexión, puesto que en éste se determinan dos partes elásticas unidas a una parte común con unas configuraciones muy especiales para adaptarse convenientemente en el interior del soporte que ya de por sí resulta complejo. DESCRIPCIÓN DE LA INVENCIÓNLikewise, in Spanish patent ES 2195229 a terminal is described that allows the connection of two cables in different directions, although not in perpendicular directions to each other, so that this terminal is enormously complex in terms of the base support, such as it is the elastic element that has to establish the connection, since in it two elastic parts are attached joined to a common part with very special configurations to adapt conveniently inside the support that is already complex in itself. DESCRIPTION OF THE INVENTION
El borne bidireccional que se preconiza, ha sido concebido para poder establecer de forma fácil, sencilla y eficaz el conexionado de cables en dos direcciones diferentes, con un coste reducido del conjunto del borne, puesto que sus piezas son sencillas, fáciles de fabricar y de acoplar entre sí.The bidirectional terminal that is recommended, has been conceived to be able to establish in an easy, simple and efficient way the connection of cables in two different directions, with a reduced cost of the whole of the terminal, since its parts are simple, easy to manufacture and of couple each other.
El borne de la invención, como es convencional, incluye dos piezas, una en funciones de soporte y otra en funciones de elemento elástico, para que en el acoplamiento entre sí permitan llevar a cabo el conexionado de los cables por introducción a través de aberturas o ventanas, quedando retenidos por la pieza elástica contra la pieza de soporte, para establecer la continuidad eléctrica correspondiente.The terminal of the invention, as is conventional, includes two pieces, one in support functions and another in functions of elastic element, so that in the coupling with each other they allow to carry out the connection of the cables by introduction through openings or windows, being retained by the elastic piece against the support piece, to establish the corresponding electrical continuity.
A partir de ese concepto, la primera característica de novedad que presenta el borne de conexión objeto de la invención reside en que la pieza elástica es única y va montada sobre la pieza de soporte en una única posición, de manera tal que permite realizar el conexionado de un cable en dos direcciones distintas, es decir, bien a través de la parte superior del conjunto del borne, bien a través de uno de sus laterales, sin variación de ningún tipo de la estructura del borne, y sin necesidad de tener que variar la posición de la pieza elástica, ni de utilizar suplementos para conseguir el referido fin.From this concept, the first novelty feature presented by the connection terminal object of the invention is that the elastic piece is unique and is mounted on the support piece in a single position, so that it allows the connection of a cable in two different directions, that is, either through the upper part of the terminal assembly, or through one of its sides, without variation of any kind of the structure of the terminal, and without having to vary the position of the elastic piece, nor of using supplements to achieve the aforementioned purpose.
El borne en cuestión podrá ser aplicado en todos aquellos productos eléctricos que requieran de una conexión de cables eléctricos y, por lo tanto, podrá ser un elemento independiente y unitario, o como parte de un elemento o conjunto de elementos, donde una parte o elemento sea el borne de conexión bidireccional sin tornillos donde se conectarán los cables eléctricos, y otra parte o resto de elementos de conjunto sea cualquier sistema que permita la continuidad eléctrica del conjunto cuando se aplica a una estación eléctrica.The terminal in question may be applied in all electrical products that require a connection of electrical cables and, therefore, may be an independent and unitary element, or as part of an element or set of elements, where a part or element be the two-way connection terminal without screws where the cables will be connected electrical, and another part or other elements of assembly is any system that allows the electrical continuity of the assembly when applied to an electrical station.
Concretamente, el borne de conexión bidireccional sin tornillos podrá ser aplicado en bornes de conexión eléctrica unitarios o múltiples, en regletas de conexión y derivación, en barras de conexión múltiple para fases, neutros o tierras eléctricas, en bornes de conexión de los contactos de las tomas de corriente, interruptores, conmutadores y de más mecanismos eléctricos para uso doméstico o análogos, en bornes de conexión de los contactos de las tomas de corriente para usos industriales, en todas las tomas de corriente independientemente de su aplicación como uso doméstico e industrial, en bases de tomas de corriente fijas o móviles o en clavijas de toma de corriente fijas o móviles, así como en contacto de base de tomas de corriente y clavija de toma de corriente desmontables o indesmontables.Specifically, the bi-directional connection terminal without screws may be applied in single or multiple electrical connection terminals, in connection and branch strips, in multiple connection bars for phases, neutrals or electrical earths, in connection terminals of the contacts of the sockets, switches, switches and more electrical mechanisms for domestic or similar use, in connection terminals of the contacts of the sockets for industrial uses, in all sockets regardless of their application as domestic and industrial use, in fixed or mobile sockets bases or in fixed or mobile sockets, as well as in removable or non-removable sockets and socket contacts.
Como es evidente, el tamaño del borne de conexión vendrá determinado por el tipo, sección o intensidad máxima del cable admisible en el borne, no existiendo a priori limitación alguna en cualquiera de los parámetros citados.As it is evident, the size of the connection terminal will be determined by the type, section or maximum intensity of the permissible cable in the terminal, there being a priori no limitation in any of the mentioned parameters.
Estructuralmente, el soporte que forma parte del borne de la invención, denominado en adelante "pieza retentora", está constituida a partir de una lámina de metal conductor debidamente troquelada en desarrollo y plegada para determinar diferentes caras planas o curvas, formando un cuerpo cúbico-poliédrico irregular en el que está establecida una cara superior formada por dos arcos convexos externamente y un arco intermedio cóncavo entre aquellos, para permitir el guiado y alojamiento en su cara interior de un rango de conductores de sección determinada y por las normas de aplicación del producto final. El arco cóncavo o cara inferior presenta una ventana central a través del cual es susceptible introducirse un útil para llevar a cabo la desconexión del conductor.Structurally, the support that forms part of the terminal of the invention, hereinafter referred to as "retaining piece", is constituted from a sheet of conductive metal duly punched in development and folded to determine different flat or curved faces, forming a cubic body. irregular polyhedral in which an upper face formed by two externally convex arcs and an intermediate concave arc between them is established, to allow the guidance and accommodation on its inner face of a range of conductors of certain section and by the product application standards final. The concave arch or lower face has a central window through which it is possible to introduce a tool for carrying out the disconnection of the conductor.
Esa pieza retentora presenta una cara frontal escalonada con una zona superior remetida respecto de la zona o parte inferior, de manera tal que en combinación con partes de la pieza elástica de conexión constituye el medio de retención de los cables conductores, cuando éstos se conectan en un determinado sentido, ya que la conexión en un sentido la conexión se establece entre unos bordes libres de la pieza elástica y las partes cóncavas correspondientes a la cara superior anteriormente referida.This retaining part has a stepped front face with an upper area tucked in relation to the lower part or zone, such that in combination with parts of the elastic connecting piece it constitutes the retention means of the conductive cables, when they are connected in a certain direction, since the connection in one direction the connection is established between free edges of the elastic piece and the concave parts corresponding to the upper face referred to above.
Asimismo, se ha previsto que la comentada pieza retentora presente frontalmente y en correspondencia con la zona inferior de las dos determinadas en el escalonamiento, con una superficie plana y centralmente con unas uñas para el enclavamiento de la pieza elástica.Likewise, it is foreseen that the said retaining piece is present frontally and in correspondence with the lower zone of the two determined in the stepping, with a flat surface and centrally with nails for the interlocking of the elastic piece.
Concretamente, la pieza elástica es una lámina flexible que está plegada sucesivamente determinando primeramente dos planos unidos entre sí por una zona de intersección curva, de manera que el primer plano queda adosado al frente de la parte plana de la pieza retentora, contando esa cara o tramo plano de la pieza elástica con una ventana en la que se ubican y enclavan las uñas de la pieza retentora, quedando hacia el exterior la otra parte plana de esa pieza elástica que tras un acodamiento también redondeado se continua plano pero en sentido ascendente, con ventanas en las que se posicionan las patillas emergentes del plano frontal o zona de intersección de las dos partes determinadas a distintas alturas en la pieza retentora.Specifically, the elastic piece is a flexible sheet that is folded successively by first determining two planes joined together by a curved intersection zone, so that the first plane is attached to the front of the flat part of the retaining piece, counting that face or flat section of the elastic piece with a window in which the nails of the retaining piece are located and interlocked, leaving the other flat part of that elastic piece to the outside which after a rounded bending is continued flat but in an upward direction, with windows in which the emerging pins of the frontal plane or intersection zone of the two parts determined at different heights in the retaining piece are positioned.
A partir de esas ventanas se continua en otro tramo recto que tras un acodamiento se proyecta en tramos oblicuos hacia arriba, para rematarse en unos bordes libres y un plano de partición, que en el montaje de tal pieza elástica sobre la pieza retentora quedan situados sobre las zonas cóncavas interiores de la parte superior de la pieza retentora, todo ello de manera tal que cuando se establece la conexión a través de la parte superior, el cable se introduce entre las conformaciones cóncavas de la parte superior de la pieza retentora y los bordes que quedan situados en esas partes cóncavas, quedando así retenido el cable e imposibilitado de sustraerse por traccionado ya que los tramos extremos y oblicuos de tal pieza elástica actúan en forma de cuña para que realicen un presionado mayor cuanto más se tracciona del cable hacia el exterior. En cuanto a la otra forma de conectar el cable, es decir lateralmente, éste se introducirá a través de las ventanas de la pieza elástica, previo empuje de ésta para permitir que el cable se aloje a través de las ventanas para que una vez cese la fuerza de empuje de tal pieza elástica ésta recupere su posición y el cable quede presionado en el interior de las ventanas por las patillas de la pieza retentora.From these windows, continue on another straight section that after an elbow is projected in oblique sections upwards, to finish off in free edges and a partition plane, which in the assembly of such elastic piece on the retaining piece are located on the interior concave areas of the upper part of the retaining piece, all this in such a way that when the connection is established through the upper part, the cable is introduced between the concave conformations of the upper part of the retaining piece and the edges that are located in those concave parts, thus retaining the cable and unable to subtract by traction since the extreme and oblique sections of such elastic piece act in the form of a wedge so that they carry out a greater pressure the more the cable is pulled outwards. As for the other way to connect the cable, that is to say laterally, it will be introduced through the windows of the elastic piece, prior to pushing it to allow the cable to lodge through the windows so that once the cable stops Pushing force of such elastic piece recovers its position and the cable is pressed inside the windows by the pins of the retaining piece.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como el borne de la invención, bidireccional sin tornillos, se constituye mediante el acoplamiento entre sí de una pieza retentora (1) y una pieza elástica y de presión (2), de manera que una vez ensambladas entre sí cuando un conductor se conecta al borne éste permite dar continuidad eléctrica al conjunto del que forma parte.In view of the aforementioned figures, it can be seen how the terminal of the invention, bidirectional without screws, is constituted by coupling together a retaining part (1) and an elastic and pressure part (2), so that once assembled together when a conductor is connected to the terminal it allows to give electrical continuity to the assembly of which it is part.
La pieza retentora (1) está formada por una lámina o metal conductor, troquelada, la cual es debidamente plegada para determinar una forma cúbico-poliédrica irregular de diferentes caras, estableciéndose una cara superior formada por dos arcos (3) convexos hacia el exterior y un arco cóncavo intermedio (4) como se ve en las figuras, con la particularidad de que el tramo o arco intermedio (4) presenta una ventana (5) que es utilizada para la introducción de la herramienta que permite la desconexión del conductor.The retaining piece (1) is formed by a sheet or conductive metal, die cut, which is duly folded to determine an irregular cubic-polyhedral shape of different faces, establishing an upper face formed by two arches (3) convex outwards and an intermediate concave arc (4) as seen in the figures, with the particularity that the intermediate section or arc (4) has a window (5) that is used for the introduction of the tool that allows the driver to disconnect.
La cara frontal de dicha pieza retentora (1) está formada en un plano de dos alturas, es decir una parte superior (6) y una parte inferior (7), quedando la primera de ellas ligeramente retranqueada, estando esa parte (6) abierta para servir de entrada de los conductores para una de las dos posibles direcciones de conexionado del borne sin tornillos, concretamente la representada en la figura 3 donde el conductor es el referenciado con el número (8), pudiéndose observar como la conexión de dos conductores (8) es posible mediante guiado de ellos en cada uno de los arcos (3) que forman la cara superior junto con el arco intermedio (4) que determina una separación entre aquellos. La diferencia de altura de la cara frontal de la pieza retentora (1) se une mediante un plano horizontal (9), hueco, cuya finalidad será el alojamiento de los conductores para el conexionado de los mismos en la otra dirección de conexionado prevista para el borne, y que corresponde a la representada en la figura 4, en la que se muestra un conductor (8') conectado en dirección perpendicular al conductor (8) conectado en el borne de la figura 2. El hueco del plano (9) referido tendrá las dimensiones apropiadas para el alojamiento de dos conductores situados en paralelo en la cara frontal, es decir como se presenta en la figura 4, donde ha sido representado un único conductor (8').The front face of said retaining piece (1) is formed in a plane of two heights, that is to say an upper part (6) and a lower part (7), the first one being slightly retracted, that part (6) being open to serve as an input for the conductors for one of the two possible directions of connection of the terminal without screws, specifically that represented in figure 3 where the conductor is referenced with the number (8), being able to observe how the connection of two conductors (8) is possible by guiding them in each of the arcs (3) that form the upper face together with the intermediate arc (4) that determines a separation between them. The difference in height of the front face of the retaining part (1) is joined by a horizontal plane (9), hollow, whose purpose will be the accommodation of the conductors for the connection of the same in the other direction of connection provided for the terminal, and corresponding to that shown in figure 4, in which a conductor (8 ') shown perpendicular to the conductor (8) connected in the terminal of figure 2 is shown. The hollow of the plane (9) referred to It will have the appropriate dimensions for the accommodation of two conductors located in parallel on the front face, that is, as shown in Figure 4, where a single conductor (8 ') has been represented.
En el borde superior del plano frontal (10) de la parte inferior (7) de la pieza retentora (1), presenta una pareja de protuberancias verticales en forma de patillas (11) que servirán de apoyo de la pieza elástica (2) y/o de apoyo de los conductores alojados en el hueco (9) referido, cuando se encuentren presionados por la pieza elástica (2) como más adelante se expondrá. Esas patillas (11) forman un discreto ángulo con el eje frontal, teniendo un plano de participación que permitirá un pequeño cambio de dirección respecto de la vertical.On the upper edge of the frontal plane (10) of the lower part (7) of the retaining piece (1), it presents a pair of vertical protrusions in the form of pins (11) that will support the elastic piece (2) and / or support of the conductors housed in the recess (9) referred to, when they are pressed by the elastic piece (2) as will be exposed later. These pins (11) form a discrete angle with the front axle, having a plane of participation that will allow a small change of direction with respect to the vertical.
En el mismo plano horizontal que delimitan las dos partes frontales (6) y (7) de la pieza retentora (1) se han previsto unos pequeños planos (12), orientados hacia el interior, para apoyo y guía de las dos caras de la pieza elástica (2), mientras que en la parte intermedia e inferior del plano frontal (10) de la parte inferior (7) de tal pieza retentora (1) presenta una pareja de uñas semicirculares (13) que en su parte inferior tendrá una ranura para el enclavamiento de la pieza elástica (2).In the same horizontal plane that delimit the two front parts (6) and (7) of the retaining piece (1), small ones are provided planes (12), oriented inwards, for support and guidance of the two sides of the elastic piece (2), while in the intermediate and lower part of the frontal plane (10) of the lower part (7) of such piece Retentive (1) presents a pair of semicircular nails (13) that will have a groove for the interlocking of the elastic piece (2).
En cuanto a las caras laterales (14) de esta pieza retentora (1), las mismas son planas y no tienen otra misión que ser parte de cohesión y cierre de la propia pieza (1), mientras que la cara posterior de ésta podrá ser cerrada por una lámina plana del mismo material u otro material distinto al de la propia pieza retentora (1), para limitar el recorrido del conductor del conexión que se conecte según la posición de la figura 3.As for the lateral faces (14) of this retaining piece (1), they are flat and have no other mission than to be part of cohesion and closing of the piece itself (1), while the rear face of the piece may be closed by a flat sheet of the same material or another material different from that of the retaining part itself (1), to limit the path of the connection conductor that is connected according to the position of figure 3.
Por su parte, la pieza elástica (2) que actuará de muelle, es una lámina también conductora, de forma plana rectangular y geométricamente doblada mediante unos pliegues determinados, pieza ésta que tiene suficiente flexibilidad para que por la actuación del conductor de conexión o de una herramienta, alcance una determinada deformación temporal y una vez concluida ésta actuación la pieza elástica (2) vuelve a su situación de reposo, creando una situación del conductor (8-8') conectado mediante presión sobre la pieza retentora (1).On the other hand, the elastic piece (2) that will act as a spring, is also a conductive sheet, of a rectangular flat shape and geometrically folded by means of certain folds, a piece that has enough flexibility so that by the action of the connecting conductor or a tool, reach a certain temporary deformation and once this action is completed the elastic part (2) returns to its resting position, creating a situation of the conductor (8-8 ') connected by pressure on the retaining part (1).
Tal pieza elástica (2) presenta un tramo plano y extremo(15) dimensionado de tal manera que se apoya directamente en la cara frontal (10) de la pieza retentora (1), presentando ese tramo plano (15) una ventana central (16) de anchura y altura coincidente con las uñas (13) de la pieza (1), para que ambas piezas (1) y (2) puedan acoplarse y quedar ensambladas entre sí.Such elastic piece (2) has a flat and end section (15) sized in such a way that it rests directly on the front face (10) of the retaining piece (1), said flat section (15) presenting a central window (16). ) of width and height coinciding with the nails (13) of the piece (1), so that both pieces (1) and (2) can be coupled and assembled together.
A continuación del tramo plano (15) la pieza elástica (2) presenta un arco (17) al que le sigue un nuevo tramo o pared plana (18), susceptible de dividirse longitudinalmente en dos mitades simétricas mediante una ranura intermedia (19), con objeto de que en aquellas normas técnicas de producto que pueda requerirse la conexión o desconexión independiente de más de un conductor en un mismo borne, puede actuarse sobre ellos de forma totalmente independiente.Following the flat section (15) the elastic piece (2) presents an arc (17) which is followed by a new section or flat wall (18), which can be divided longitudinally into two symmetrical halves by means of an intermediate groove (19), so that in those technical product standards the connection may be required or independent disconnection of more than one conductor in the same terminal, they can be acted upon completely independently.
Las caras o tramos planos comentados (15) y (18) de la pieza elástica (2) forman entre sí un cierto ángulo tangente al arco (17), continuándose el tramo plano (18), tras un acodamiento o arco (20), en un tramo superior y plano (21) con una cierta inclinación ascendente, estableciéndose en este tramo plano (21), en cada una de sus dos mitades si las hubiera, una ventana rectangular (22) con los ángulos redondeados, de manera tal que las dimensiones de esta ventana o ventanas corresponderán a la superficie necesaria para introducir por ella los conductores de conexión (8') de las secciones adecuadas para el rango e intensidades admisibles para los que esté concebido el producto eléctrico que incorpore este borne bidireccional sin tornillo.The faces or flat sections mentioned (15) and (18) of the elastic piece (2) form a certain angle tangent to the arc (17), continuing the flat section (18), after a bend or arc (20), in a flat and upper section (21) with a certain ascending inclination, establishing in this flat section (21), in each of its two halves if there were, a rectangular window (22) with rounded angles, so that the dimensions of this window or windows will correspond to the surface necessary to introduce through it the connection conductors (8 ') of the sections suitable for the range and allowable intensities for which the electrical product that incorporates this bi-directional terminal without screw is designed.
Ese tramo plano (21) se continúa en otro tramo (23) también plano, que se acoda según un arco (24), en sentido ascendente, para continuarse en un nuevo tramo plano (25) ascendente, de forma prácticamente vertical, de manera que la inclinación de este tramo (25) vendrá determinada por la presión que sea necesaria realizar sobre el conductor de conexión (8) y por el tipo de conductores de conexión a los que sea aplicable este borne direccional sin tornillo, de manera que para asegurar la eficacia de esta presión dicho tramo plano y superior (25) se remata en un pequeño plano de partición (26) que modula la inclinación del tramo (25).That flat section (21) is continued in another section (23) also flat, which is bent along an arc (24), in ascending direction, to continue in a new upward plane section (25), practically vertically, so that the inclination of this section (25) will be determined by the pressure that it is necessary to make on the connecting conductor (8) and by the type of connection conductors to which this screwless directional terminal is applicable, so as to ensure The efficiency of this pressure said flat and upper section (25) is finished off in a small partition plane (26) that modulates the inclination of the section (25).
La ranura intermedia (19) divide la lámina correspondiente a la pieza elástica (2) en dos secciones rectangulares, de caras paralelas, excepto en la zona correspondiente al plano de partición (26), donde las caras interiores no son paralelas respecto de las anteriores sino que tienen un cierto ángulo formando un trapecio o rectángulo.The intermediate groove (19) divides the sheet corresponding to the elastic piece (2) in two rectangular sections, with parallel faces, except in the area corresponding to the partition plane (26), where the inner faces are not parallel with respect to the previous ones but have a certain angle forming a trapezoid or rectangle.
En base a estas características del borne, el funcionamiento del mismo es como sigue.Based on these characteristics of the terminal, its operation is as follows.
Para un correcto funcionamiento las piezas retentora (1) y elástica (2) deben ensamblarse entre sí, formando un conjunto como el mostrado en la figura 2, para lo cual la parte o cara plana (10) de la pieza retentora (1) deberá estar enfrentada y superpuesta a la pared o tramo plano (15) de la pieza elástica (2), coincidiendo las uñas (13) de aquella con la ventana (16), introduciéndose dichas uñas (13) en la propia ventana para quedar así enclavadas ambas piezas (1) y (2). Simultáneamente, las patillas verticalesFor proper operation, the retaining (1) and elastic (2) pieces must be assembled together, forming an assembly as shown in Figure 2, for which the flat part (10) of the retaining part (1) must be facing and superimposed on the wall or flat section (15) of the elastic piece (2), the nails (13) of the latter coinciding with the window (16), said nails (13) being introduced into the window itself to be thus locked both pieces (1) and (2). Simultaneously, the vertical pins
(19) de la pieza retentora (1) serán encajadas en las ventanas (22) de la pieza elástica (2), mientras que la cara o tramo plano (25) de la pieza elástica (2) se introducirá en el interior de la pieza retentora (1), quedando en correspondencia con las concavidades internas (3) de la parte superior de la pieza retentora, de manera que la citada geometría de ambas piezas hace que estas queden perfectamente ensambladas manteniendo una total flexibilidad de la pieza elástica (2) para posibilitar el apriete de los conductores (8) u (8') sin necesidad de tornillos.(19) of the retaining piece (1) will be fitted in the windows (22) of the elastic piece (2), while the flat face (25) of the elastic piece (2) will be inserted inside the retaining piece (1), being in correspondence with the internal concavities (3) of the upper part of the retaining piece, so that said geometry of both pieces makes them perfectly assembled maintaining a total flexibility of the elastic piece (2 ) to enable the tightening of the conductors (8) or (8 ') without the need for screws.
Para la conexión del conductor (8) en la dirección indicada en la figura 3, es decir en una de las direcciones de conexionado, se introducirá tal conductor (8) a través de la parte abierta (6) de la pieza retentora (1), presionando el tramo plano (25) de la pieza elástica (2) con la punta del conductor (8) pelado, de manera que la geometría circular de la parte superior de la pieza retentora (1), es decir de las dos partes cóncavas, y la pendiente y flexión por empuje de la pieza elástica (2), permiten el guiado del conductor (8) hacia un pequeño hueco existente entre tal pieza elástica (2) y la pieza retentora (1), quedando presionado y enclavado.For the connection of the conductor (8) in the direction indicated in figure 3, that is to say in one of the connection directions, such conductor (8) will be introduced through the open part (6) of the retaining part (1) , pressing the flat section (25) of the elastic part (2) with the conductor tip (8) stripped, so that the circular geometry of the upper part of the retaining part (1), that is to say of the two concave parts , and the slope and push flexion of the elastic part (2), allow the driver to guide (8) towards a small gap between said elastic part (2) and the retaining part (1), being pressed and locked.
Introducido el conductor (8) entre la pieza retentora (1) y la pieza elástica (2), como se representa en la figura 3, si se tracciona de dicho conductor hacia fuera se produce al mismo tiempo una tracción de la pieza elástica (2), que al tener la pendiente del tramo plano (25) en sentido inverso, presiona más el conductor (8) sobre la pieza retentora (1) impidiendo la salida de aquél. De hecho, para soltar el conductor (8) habrá que introducir una herramienta o elemento de presión por la ventana (5) de la pieza retentora (1), empujando la pieza elástica (2) para abrir hueco entre ésta y la pieza retentora (1), liberándose así la presión sobre el conductor (8) y permitir la salida de éste.Introduced the conductor (8) between the retaining part (1) and the elastic part (2), as shown in Figure 3, if it is pulled from said conductor out there is at the same time a traction of the elastic part (2 ), that having the slope of the flat section (25) in the opposite direction, further presses the conductor (8) on the retaining part (1) preventing its exit. In fact, to release the conductor (8), a tool or pressure element must be introduced through the window (5) of the retaining part (1), pushing the elastic part (2) to open a gap between it and the retaining part ( 1), thus releasing the pressure on the conductor (8) and allowing it to exit.
La conexión del conductor (8'), es decir en la otra dirección posible del borne bidireccional sin tornillos, se realiza haciendo palanca con una herramienta sobre el pliegue (20) de la pieza elástica (2), provocando un giro angular sobre el centro del pliegue o arco (17), desplazando la ventana (22) hacia el interior de la pieza retentora (1), hasta enfrentarlo con el hueco (9) de la misma, de manera que en esa posición se introducirá el conductor (8') por la ventana (22) y se dejará de ejercer la presión con la herramienta, permitiendo la pieza elástica (2) recuperar su posición original, provocando un aprisionamiento del propio conductor (8') entre la ventana (22) de la pieza elástica (2) y la respectiva patilla (11) de la pieza retentora (1), todo ello de manera tal que el efecto cizalla de la ventana (22) de la pieza elástica (2) impide que el conductor (8') pueda extraerse mediante una tracción axial del mismo, siendo necesario para desconectar tal conductor hacer la operación inversa. The connection of the conductor (8 '), that is to say in the other possible direction of the two-way terminal without screws, is done by prying with a tool on the fold (20) of the elastic piece (2), causing an angular rotation on the center of the fold or arch (17), moving the window (22) towards the inside of the retaining piece (1), until facing it with the recess (9) thereof, so that in that position the conductor (8 'will be introduced ) through the window (22) and the pressure with the tool will cease, allowing the elastic part (2) to recover its original position, causing a clamping of the conductor itself (8 ') between the window (22) of the elastic part (2) and the respective pin (11) of the retaining part (1), all in such a way that the shear effect of the window (22) of the elastic piece (2) prevents the conductor (8 ') from being removed by axial traction thereof, it being necessary to disconnect such conductor to make the or reverse peration.
