Specifically, the type of those that incorporate a coil that, when energized, drives a magnetic circuit acting on a terminal switch, which carries out the selective connection of terminals that are connected to the contacts of said switch.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la actualidad, se conocen soluciones encaminadas a asistir el funcionamiento de los relés empleando circuitos electrónicos que, a expensas de una señal recibida, actúan sobre la bobina de excitación del relé electromagnético. Por ejemplo, el circuito Currently, solutions are known to assist the operation of the relays using electronic circuits that, at the expense of a received signal, act on the excitation coil of the electromagnetic relay. For example, the circuit
electrónico puede consistir en un temporizador, un amplificador, un detector de control de rotación de fase, etc., según los tipos de componentes electrónicos que han sido acoplados al circuito impreso. Electronic can consist of a timer, an amplifier, a phase rotation control detector, etc., according to the types of electronic components that have been coupled to the printed circuit.
Por ejemplo, son empleados circuitos supresores con diodos, varistores, condensadores, etc., conectados en paralelo o en serie con la bobina del relé, For example, suppressor circuits are used with diodes, varistors, capacitors, etc., connected in parallel or in series with the relay coil,
encaminados a conseguir protección contra sobretensiones instantáneas conducidas en las líneas o generadas por el propio relé al desconectar la bobina. aimed at achieving protection against instantaneous surges conducted in the lines or generated by the relay itself when disconnecting the coil.
Estos circuitos pueden encontrase situados en el exterior del relé, para lo cual es preciso disponer de
un zócalo especialmente diseñado a este fin, o bien, en el interior del relé. These circuits can be located on the outside of the relay, for which it is necessary to have A socket specially designed for this purpose, or in the interior of the relay.
Asi, se han intentado soluciones que alojan el circuito electrónico en un módulo independiente del conjunto relé-base, es decir, dispuesto de forma anexa a dicho conjunto relé-base, lo cual, implica la ocupación de un importante espacio, con el que, en la mayoría de los casos, no se cuenta, además de ser imprescindible la realización de conexiones exteriores entre uno y otro elemento . Thus, solutions have been tried to accommodate the electronic circuit in a module independent of the relay-base assembly, that is, arranged in an annexed manner to said relay-base assembly, which implies the occupation of an important space, with which, in the majority of cases, it is not counted, in addition to being essential the realization of external connections between one and another element.
Otro caso de disposición del circuito Another case of circuit layout
electrónico al exterior del relé es el mostrado en el documento de patente ES 287790, publicado el 16 de mayo de 1986, en el cual, el módulo electrónico se dispone entre un relé estándar y su correspondiente base de enchufe, con vistas a modificar la actuación de la bobina del relé y ejercer sobre ella un determinado control regulable. Si bien, en este caso, no se The electronic module on the outside of the relay is shown in patent document ES 287790, published on May 16, 1986, in which the electronic module is arranged between a standard relay and its corresponding socket outlet, in order to modify the performance of the relay coil and exercise a certain adjustable control over it. Although, in this case, it is not
requieren conexiones exteriores ni modificaciones adicionales a la base de enchufe del relé, implica la adquisición de un elemento adicional. require external connections or additional modifications to the socket base of the relay, implies the acquisition of an additional element.
Por tal razón, las soluciones preferidas por el personal técnico son las que el circuito electrónico va dispuesto en el interior del relé, pues facilita las labores de instalación y mantenimiento, ya que permite emplear las bases estándares comercializadas actualmente o ya instaladas sin requerirse elemento adicional alguno. Sin embargo, el alojamiento de estos circuitos electrónicos en el interior del relé presupone un gran problema debido a las dimensiones reducidas de los espacios disponibles.
Por ejemplo, el documento de patente EP For this reason, the preferred solutions by the technical staff are those that the electronic circuit is arranged inside the relay, as it facilitates the installation and maintenance work, since it allows to use the standard bases currently marketed or already installed without requiring additional element any. However, the housing of these electronic circuits inside the relay presupposes a big problem due to the small dimensions of the available spaces. For example, the EP patent document
03008547, publicado el 29 de marzo de 1989, el cual muestra un relé electromagnético con dispositivo de señalización luminosa, constituido por un soporte al cual se fija una base que soporta un circuito impreso que incluye un LED y una resistencia. Dos conductores conectan el circuito impreso a la bobina del relé para alimentar a dicho circuito impreso y a sus componentes. 03008547, published March 29, 1989, which shows an electromagnetic relay with light signaling device, constituted by a support to which a base that supports a printed circuit that includes an LED and a resistance is fixed. Two conductors connect the printed circuit to the relay coil to feed the printed circuit board and its components.
Otro ejemplo, es el relé electromagnético mostrado en el documento de patente ES 2160083, Another example is the electromagnetic relay shown in patent document ES 2160083,
publicado el 16 de octubre de 2001, el cual, comprende una placa de circuito impreso que dispone una serie de componentes electrónicos encaminados a la protección del relé. El circuito impreso comprende una serie de published on October 16, 2001, which comprises a printed circuit board that has a series of electronic components for the protection of the relay. The printed circuit comprises a series of
taladros estañados coincidentes con unos terminales de la bobina, dos de ellos, conectados al carrete de la bobina, y otros dos, son prolongaciones de los tinned holes coinciding with coil terminals, two of them, connected to the spool of the coil, and two others, are extensions of the
terminales de alimentación. power terminals.
Estas soluciones conocidas tienen la desventaja de que el circuito electrónico esté conectado de forma directa a la alimentación de la bobina, lo cual, limita a que el circuito electrónico se encamine a controles sencillos del relé, por ejemplo, su protección, These known solutions have the disadvantage that the electronic circuit is directly connected to the power supply of the coil, which limits the electronic circuit to simple controls of the relay, for example, its protection,

Resulta un problema que los actuales relés estén diseñados para tensiones de alimentación especificas, por ejemplo, entre las más habituales, 24 VDC y 230 VAC . Esto trae consigo la necesidad de que los distribuidores mantengan un stock de relés de diferentes tensiones de
alimentación para poder hacer frente a las múltiples demandas de sus clientes, pues, en el caso de que se solicite un relé para tensiones distintas a las It is a problem that the current relays are designed for specific supply voltages, for example, among the most common, 24 VDC and 230 VAC. This brings with it the need for distributors to maintain a stock of relays of different voltages feed to meet the multiple demands of its customers, then, in the case that a relay is requested for tensions other than those
disponibles en sus almacenes, tienen que pedirlo a la fábrica, lo cual, implica demoras en la entrega del producto, y en muchos casos, una pérdida de venta. available in their warehouses, they have to ask the factory, which implies delays in the delivery of the product, and in many cases, a loss of sale.
Por tal razón, se requiere diseñar, de forma sencilla y económica, un relé electromagnético que permita superar los inconvenientes anteriormente For this reason, it is required to design, in a simple and economical way, an electromagnetic relay that allows to overcome the inconveniences previously.
