Description

"CARCASA PARA APARATOS ELÉCTRICOS" "HOUSING FOR ELECTRICAL EQUIPMENT"
En las instalaciones de suministro eléctrico se disponen aparatos de interrupción automática de la corriente, a efectos de seguridad y para establecer las limitaciones necesarias frente a las sobrecorrientes que superen los límites previstos .In the power supply facilities, automatic power interruption devices are provided, for safety purposes and to establish the necessary limitations against overcurrents that exceed the expected limits.
A estos efectos se utilizan aparatos disyuntores, los cuales pueden instalarse acoplados a detectores de corriente diferencial, estableciéndose las conexiones necesarias mediante cables exteriores de interconexión entre los aparatos respectivos.Circuit breakers are used for these purposes, which can be installed coupled to differential current detectors, establishing the necessary connections by means of external interconnection cables between the respective devices.
La disposición externa de los cables de conexión obliga a utilizar cables forrados con una cubierta aislante, lo cual sin embargo no asegura con la debida garantía el aislamiento, ya que los cables quedan sin más protección que su recubrimiento, el cual puede resultar dañado, con el consiguiente riesgo de descargas o cortocircuitos .The external arrangement of the connection cables requires the use of cables covered with an insulating cover, which, however, does not ensure the insulation with due guarantee, since the cables are left without more protection than their coating, which can be damaged, with the consequent risk of discharges or short circuits.
Por otro lado, los aparatos detectores de corriente diferencial se constituyen por un conjunto estructural en el que resulta complicado el montaje de los mecanismos correspondientes, así como el acoplamiento de la unión entre las partes que determinan la carcasa exterior respectiva. De acuerdo con la presente invención se propone una carcasa destinada para aparatos eléctricos y en particular para dichos aparatos detectores de corriente diferencial, con la cual se obtienen unas características que solucionan satisfactoriamente esos problemas anteriormente indicados, aportando ventajas esencialmente importantes de carácter constructivo y funcional.On the other hand, the differential current detecting devices are constituted by a structural assembly in which the assembly of the corresponding mechanisms is complicated, as well as the coupling of the joint between the parts that determine the respective outer casing. In accordance with the present invention, a housing intended for electrical appliances and in particular for said differential current detection devices is proposed, with which characteristics are obtained that satisfactorily solve those problems indicated above, providing essentially important advantages of a constructive and functional nature.
Esta carcasa objeto de la invención consiste en un zócalo y una tapa, que determinan el alojamiento de los mecanismos del aparato, estableciéndose el acoplamiento entre dichos elementos mediante ion simple encaje y la retención por enganche entre respectivas conformaciones de engatillado, mientras que en relación con el mencionado conjunto se acopla frontalmente una pieza que queda sobresaliendo hacia un lateral, la cual determina una conformación prominente que encaja por el frente abierto del zócalo, quedando apresada por una pieza complementaria que se incluye por encima en sujeción engatillada respecto de las paredes del zócalo y que determina los alojamientos de las bomas de conexión, quedando la pieza frontal con posibilidad de un juego limitado de movimiento en los sentidos de inserción y extracción, en tanto que dicha pieza determina por la parte exterior unos acanalados que se extienden parcialmente a lo largo de ella, prologándose por la conformación de encaje hasta el extremo de ésta, en los cuales acanalados son alo abíes los cables de conexión externa del aparato con el respectivo disyuntor.This housing object of the invention consists of a socket and a cover, which determine the housing of the mechanisms of the apparatus, establishing the coupling between said elements by simple ion fitting and retention by engagement between respective crimping conformations, while in relation to the aforementioned assembly, a piece that is protruding towards one side is engaged frontally, which determines a prominent conformation that fits by the open front of the socket, being seized by a complementary piece that is included above in clamped fastening with respect to the walls of the socket and that determines the housings of the connecting bums, leaving the front piece with the possibility of a limited play of movement in the directions of insertion and removal, as that said part determines on the outside some flutes that extend partially along it, being prologized by the conformation of lace to the end of it, in which flutes are located open the external connection cables of the apparatus with the respective circuit breaker .
La disposición de la pieza frontal permite el posicionamiento de ésta para situar el disyuntor lateralmente adosado, mientras que con el movimiento posterior de dicha pieza hacia adentro del zócalo, se determina la inclusión de los cables conectores en relación con las bornas del disyuntor.The arrangement of the front piece allows its positioning to position the laterally attached circuit breaker, while with the subsequent movement of said part into the socket, the inclusion of the connecting cables in relation to the terminals of the circuit breaker is determined.
Sobre la mencionada pieza frontal se incorpora por fuera una tapa de sujeción por clipado, que cubre los acanalados de alojamiento de los cables; mientras que sobre el borde superior de la parte que sobresale lateralmente se incorporan unas piezas accesorias insertables a guía y fijación por bloqueo mediante un botón de engatillado, desde las cuales salen en proyección unas lengüetas que se sitúan sobre las bornas del disyuntor, precintando el acceso a las mismas.On the aforementioned front piece, a clamping cover is incorporated on the outside, which covers the cable housing grooves; while on the upper edge of the part that protrudes laterally, accessory inserts are incorporated to guide and fixation by means of a crimp button, from which projections come out of tabs that are placed on the terminals of the circuit breaker, sealing the access to them.
Sobre la zona de las bornas del propio aparato detector de la corriente diferencial se dispone a su vez una tapa en montaje basculable, la cual es susceptible de aseguramiento en cierre mediante un precinto accesorio, para impedir el acceso a dichas bornas por personas no autorizadas .On the area of the terminals of the differential current detection device itself, there is also a tiltable mounting cover, which is capable of closing assurance through an accessory seal, to prevent access to said terminals by unauthorized persons.
El mecanismo interruptor del mencionado aparato detector de la corriente diferencial se dispone en un soporte que incluye una lengüeta, mediante la cual se establece el montaje de sujeción de dicho soporte por inserción en una ranura de encaje definida en una pared lateral del zócalo. Se obtiene así una carcasa cuyo conjunto es muy fácil de acoplar para la realización del montaje, ya que todas las uniones se establecen por un simple encaje entre los elementos componentes .The switch mechanism of said differential current sensing apparatus is arranged in a support that includes a tongue, by means of which the mounting of said support is established by insertion into a groove of defined groove in a side wall of the socket. A housing is thus obtained whose assembly is very easy to attach for the assembly, since all the connections are established by a simple fit between the component elements.
El conexionado con respecto al disyuntor correspondiente es a su vez fácilmente realizable, por la movilidad de la pieza alojadora de los cables de conexión; en tanto que para la mencionada conexión pueden utilizarse cables desnudos, quedando estos perfectamente aislados en sus alojamientos, sin ninguna posibilidad de que accidentalmente puedan llegar a contactar entre sí, o de que se pueda establecer con ellos un contacto exterior con riesgo de descarga eléctrica.The connection with respect to the corresponding circuit breaker is in turn easily achievable, due to the mobility of the housing part of the connection cables; while for the mentioned connection, bare wires can be used, these being perfectly isolated in their housings, without any possibility that they could accidentally contact each other, or that an external contact with risk of electric shock could be established with them.
Por todo lo cual, esta carcasa preconizada resulta ciertamente de unas características muy ventajosas, adquiriendo vida propia de por sí y carácter preferente de aplicación en los aparatos para los que se halla destinada.Therefore, this recommended housing is certainly of very advantageous characteristics, acquiring its own life of its own and preferential character of application in the devices for which it is intended.
