La presente invención se refiere a cajas para aparellaje eléctrico, aportando sensibles ventajas sobre la técnica actualmente conocida.The present invention relates to boxes for electrical equipment, providing significant advantages over the technique currently known.
Las cajas objeto de la presente invención estarán destinadas especialmente a recibir enchufes de conexión para aparatos externos, así como otros elementos y los correspondientes magneto-térmicos.The boxes object of the present invention will be specially designed to receive connection plugs for external devices, as well as other elements and the corresponding magneto-thermal.
Como es sabido, en la actualidad existe en el mercado una gran variedad de tipos de enchufes que difieren ligeramente en sus dimensiones y estructura, especialmente en la forma de fijación. Ello representa una dificultad sensible en la adaptación de enchufes a una caja de aparellaje, puesto que se presentan problemas de adaptación por las ligeras diferencias mencionadas que se reducen en muchos casos a diferencias en el número y separación relativa de los orificios de fijación mediante tornillos de los enchufes a la caja.As is known, it currently exists in the market a variety of types of plugs that differ slightly in its dimensions and structure, especially in the fixing way. This represents a sensitive difficulty in adaptation of plugs to a switchgear box, since it have adaptation problems due to slight differences mentioned that are reduced in many cases to differences in number and relative separation of fixing holes by screws from the plugs to the box.
El documento ES2214159, del inventor de la presente invención, da a conocer una caja destinada a solucionar el inconveniente mencionado, al establecer medios para que la caja pueda admitir cualquiera de una amplia variedad de enchufes con estructuras de fijación distintas. En particular, dicho documento da a conocer una caja que prevé la realización de cada una de las zonas de acoplamiento de los enchufes mediante una base rehundida en la propia caja y una placa acoplable individualmente a cada una de ellas de modo que, tanto cada una de las bases como las placas acoplables correspondientes presentan una multitud de grupos de cavidades no totalmente perforadas agrupadas en juegos, en las proximidades de las esquinas, cada uno de los cuales se corresponde a uno de los tipos de enchufes existentes en el mercado. Ello se consigue al moldear tanto la caja como las placas postizas con la multitud de cavidades indicada agrupadas por conjuntos que corresponden a distintos enchufes del comercio. En esta situación, al montar cualquier enchufe, el instalador utilizará el juego de cavidades que se adapta al enchufe que desea montar, debiendo efectuar simplemente el taladrado definitivo de las cavidades, para facilitar lo cual éstas presentarán estrechos tabiques en su fondo, de fácil eliminación en el momento del montaje.Document ES2214159, of the inventor of the present invention, discloses a box intended to solve the mentioned inconvenience, when establishing means for the box can support any of a wide variety of plugs with different fixing structures. In particular, said document gives to know a box that provides for the realization of each of the areas of coupling of the plugs by means of a recessed base in the own box and a plate individually attachable to each of them so that both each of the bases and the plates corresponding docks have a multitude of groups of not fully perforated cavities grouped into games, in near corners, each of which corresponds to one of the types of plugs in the market. Them and achieved by molding both the box and the false plates with the multitude of cavities indicated grouped by sets that correspond to different plugs of the trade. In this situation, when mounting any plug, the installer will use the set of cavities that adapt to the plug you want to mount, simply carry out the final drilling of the cavities, to facilitate which these will present narrow partitions at the bottom, Easy removal at the time of assembly.
Sin embargo, la caja para aparellaje dada a conocer en dicho documento, debido a que presenta en el moldeo de la propia tapa cavidades para acoplamiento de diferentes enchufes, resulta únicamente para enchufes cuyas dimensiones generales (altura, anchura) difieren entre sí de manera ligera. Sin embargo, no resulta válida para enchufes cuyas dimensiones generales varían sustancialmente. En particular, se plantea el problema de la existencia de enchufes con interblocante o dispositivo de enclavamiento, que presentan una zona de enchufe y una zona de mando interruptor de bloqueo del sistema. Por ello, dichos enchufes presentan una altura considerablemente mayor que su anchura, con una relación altura-anchura considerablemente distinta a la del resto de enchufes. De acuerdo con la solución aportada en el documento ES2214159, para prever la instalación de enchufes con interblocante, sería necesario prever cavidades específicas para este tipo de enchufes cuya relación de dimensiones varía sustancialmente con respecto al resto de enchufes, y por lo tanto, resultaría necesario realizar, además, tapas específicas para aparellajes que comprendan enchufes con interblocante.However, the box for equipment given to know in that document, because it presents in the molding of the own cavity cover for coupling different plugs, It is only for sockets whose overall dimensions (height, width) differ slightly from each other. But nevertheless, not valid for sockets whose general dimensions vary substantially. In particular, the problem of existence of plugs with interlocking device or interlocking, which have a plug and a control zone system lock switch. Therefore, said plugs they have a height considerably greater than their width, with a height-to-width ratio considerably different from the rest of the plugs. According to the solution provided in the document ES2214159, to provide for the installation of plugs with interlocking, it would be necessary to provide specific cavities for this type of plugs whose ratio of dimensions varies substantially with respect to the rest of the plugs, and therefore, it would also be necessary to make specific caps for aparellajes that include plugs with interlocking.
Para dar una solución a los problemas planteados, la presente invención hace referencia a una caja de las características antes citadas, es decir, una que presenta una base y una tapa de cierre moldeadas estando la tapa destinada a recibir en la cara frontal de la misma enchufes eléctricos de dimensiones variadas, presentando zonas de acoplamiento de los enchufes que comprenden múltiples grupos de cavidades, permitiendo al instalador escoger el grupo de cavidades deseado para la inserción de los tornillos de fijación de los enchufes en el momento de la instalación, y se caracteriza porque dichos grupos de cavidades se sitúan en al menos una pieza de conexión independiente que se acopla mecánicamente a la tapa, quedando ésta libre de dichos grupos de cavidades para inserción de los tornillos de los enchufes.To give a solution to the problems raised, The present invention refers to a box of characteristics mentioned above, that is, one that presents a basis and a molded closure cap with the lid intended to receive in the front face of the same electrical plugs of dimensions varied, presenting areas of coupling of the plugs that They comprise multiple groups of cavities, allowing the installer choose the desired group of cavities for the insertion of the fixing screws of the plugs at the time of installation, and it is characterized in that said groups of cavities are placed in at least one independent connecting piece that engages mechanically to the lid, this being free of said groups of cavities for inserting the screws of the plugs.
Como se comprende, al dejar libre la tapa de los orificios para atornillado de enchufes, es posible utilizar la misma tapa de la caja para todo tipo de enchufes, incluso para enchufes cuya relación de dimensiones generales es muy variable entre sí. Para ello, las cavidades se disponen en piezas independientes. Esto da la posibilidad al instalador de elegir diferentes tipos de piezas de conexión independientes para enchufes cuyos orificios de atornillado presentan dimensiones altamente diferentes. Otra ventaja de la presente invención es que permite optimizar el espacio utilizado, puesto que cada pieza de conexión independiente podrá comprender orificios para conexión de uno o varios enchufes, en función de sus tamaños, todo ello sin que la tapa sufra alteración alguna en cuanto a su fabricación.As understood, by leaving the lid of the holes for screwing plugs, it is possible to use the same box cover for all types of plugs, even for plugs whose relation of general dimensions is very variable among themselves. For this, the cavities are arranged in separate pieces. This gives the installer the possibility to choose different types of parts independent connection for sockets whose holes are Screwed have highly different dimensions. Another advantage of the present invention is that it allows to optimize the space used, since each independent connection piece can comprise holes for connection of one or more plugs, in depending on their sizes, all without the cover suffering alteration Some as for its manufacture.

Tal como se observa en las figuras, la caja para aparellaje eléctrico objeto de la presente invención se compone de una base (1) y una tapa (2) acoplables entre sí para integrar la caja, presentando la tapa (2) una zona superior (3) con una abertura (4) para permitir el montaje de magneto-térmicos, y el acceso a los mismos, quedando protegidos mediante la tapa basculante (5), presentando, además dicha tapa (2) una serie de zonas rehundidas para recibir las piezas de conexión tales como las indicadas con los numerales (6), (7) y (8), dotadas de aberturas, en las que se acoplarán piezas de conexión que recibirán los enchufes de diferentes tipos.As shown in the figures, the box for Electrical equipment object of the present invention is composed of a base (1) and a cover (2) attachable to each other to integrate the box, the lid (2) presenting an upper area (3) with an opening (4) to allow magneto-thermal mounting, and access to them, being protected by the cover tilting (5), further presenting said cover (2) a series of recessed areas to receive connection pieces such as indicated with numerals (6), (7) and (8), equipped with openings, in which will be connected connection pieces that will receive the plugs of different kinds.
Dichas zonas rehundidas (6), (7) y (8), pueden recibir, encajadas y retenidas, piezas de conexión tales como las placas (13), (13') y (13''), que se han representado en la figura 1 en posición desmontada con respecto a la tapa (2) y en posición montada en las figuras 8 y 10.Said recessed zones (6), (7) and (8), may receive, embedded and retained, connection pieces such as plates (13), (13 ') and (13' '), which are shown in Figure 1 in disassembled position with respect to the cover (2) and in position mounted on figures 8 and 10.
Dichas placas se acoplan a la tapa (2) de la caja mediante medios mecánicos, tales como, por ejemplo, las patillas (131), (132), (133), (134), u otros medios simples y de fácil desmontaje.Said plates are attached to the lid (2) of the box by mechanical means, such as, for example, the pins (131), (132), (133), (134), or other simple and easy means disassembly
Es característico de la presente invención que las placas de acoplamiento (13), (13''), presenten cerca de sus bordes grupos de cavidades tales como las indicadas con los numerales (14) y (15), mientras que las zonas rehundidas (6), (7), (8) en las que se acoplan las piezas de conexión independientes (13), (13'), (13''), carezcan de dichos grupos de cavidades. De esta manera, es posible acoplar a la caja, con facilidad, enchufes cuya relación dimensional es muy diferente, tales como la diferencia que existen entre los enchufes designados con los numerales (41), (42), (43) y (44) y el enchufe (40) que, además de la conexión para enchufe (40'), presenta un dispositivo interblocante (40''). Para ello, dichos enchufes se colocan en piezas de conexión diferentes.It is characteristic of the present invention that the coupling plates (13), (13``), present near their edges groups of cavities such as those indicated with the numerals (14) and (15), while recessed areas (6), (7), (8) in which the independent connection pieces are coupled (13), (13 '), (13' '), lack such groups of cavities. This way, it is possible to attach to the box, easily, plugs whose dimensional relationship is very different, such as the difference that they exist between the sockets designated with the numerals (41), (42), (43) and (44) and the plug (40) which, in addition to the connection for plug (40 '), presents an interlocking device (40' '). For this, said plugs are placed in connection pieces different.
En las figuras 2 a 4 se ha representado una pieza de conexión independiente (13) que dispone de dos zonas de instalación de un enchufe, separados por una zona elevada (30). Cada zona para instalación de enchufe dispone de agrupaciones de orificios para atornillado del enchufe, tales como las marcadas con los numerales (14) y (15). Se podrá observar que, una vez conectada mecánicamente a la tapa (2) de la caja, esta pieza de conexión dota a la misma de las cavidades de interconexión de la caja descrita en el documento ES 2214159. En la figura 4 se ha representado la pieza (13) antes citada, sobre la que se han montado dos enchufes diferentes (41), (42). Como se observará, mientras que el enchufe indicado con el numeral (42) ha sido atornillado directamente a las cavidades de la pieza de conexión (13), el otro enchufe (41) ha sido atornillado con intermedio de una placa auxiliar (101) dotada de otros conjuntos de cavidades para atornillar (14'), (15'). Las características de los conjuntos de cavidades (14), (15), (14'), (15') así como de la pieza o placa auxiliar (101) se encuentran descritas, por ejemplo, en el documento ES 2214159, y permiten que el instalador cubra casi la totalidad de los enchufes conocidos en el mercado.In figures 2 to 4 a piece is shown of independent connection (13) that has two zones of installation of a plug, separated by an elevated area (30). Every Plug installation area has clusters of holes for screwing the plug, such as those marked with numerals (14) and (15). It will be noted that once connected mechanically to the lid (2) of the box, this connecting piece provides to it of the interconnection cavities of the box described in document ES 2214159. The part has been shown in figure 4 (13) above, on which two plugs have been mounted different (41), (42). As will be seen, while the plug indicated with numeral (42) has been screwed directly to the cavities of the connection piece (13), the other plug (41) has been screwed through an auxiliary plate (101) equipped with other sets of cavities for screwing (14 '), (15'). The characteristics of cavity assemblies (14), (15), (14 '), (15 ') as well as the part or auxiliary plate (101) are described, for example, in document ES 2214159, and allow the installer covers almost all known plugs in the market.
Sin embargo, para la instalación de enchufes, por ejemplo, de forma general alargada, tales como el enchufe (40) que además de la zona de conexión (40') disponen de dispositivo interblocante (40'') resulta necesario disponer de medios distintos a los mostrados en las figuras 2 a 4. En las figuras 5 a 8 se muestra una pieza de conexión (13'), formada por una zona central (31) de recepción del enchufe (40) con interblocante, dotada de cavidades (34), (35) para atornillado de dicho enchufe con interblocante, así como sendas zonas elevadas (32), (33), destinadas a cubrir la diferencia de longitud entre el enchufe con interblocante (40) y la zona de recepción correspondiente (7) del frontal de la caja (2).However, for the installation of plugs, by example, generally elongated, such as the plug (40) that In addition to the connection area (40 ') they have a device interlocking (40 '') it is necessary to have different means to those shown in figures 2 to 4. Figures 5 to 8 show shows a connection piece (13 '), formed by a central area (31) receiving the plug (40) with interlock, equipped with cavities (34), (35) for screwing said plug with interlocking, as well as elevated areas (32), (33), intended to cover the difference in length between the plug with interlocker (40) and the corresponding reception area (7) of the front of the box (2).
Mediante los medios mostrados, es posible utilizar una misma base (1) y tapa (2) para todo tipo de enchufes, incluyendo aquellos dispuestos con dispositivo interblocante, dando libertad al instalador para elección del tipo y número de enchufes a instalar y su disposición en la caja. Las cavidades de los grupos indicados, tanto en las bases de acoplamiento como en las placas auxiliares, presentarán para el instalador la posibilidad de escoger el conjunto que se adapte al enchufe deseado, roscando los tornillos de sujeción en las paredes internas de dichas cavidades.Through the means shown, it is possible use the same base (1) and cover (2) for all types of plugs, including those willing with interlocking device, giving freedom to the installer to choose the type and number of plugs to install and its arrangement in the box. The cavities of the groups indicated, both on the coupling bases and on the plates auxiliary, will present to the installer the possibility of choosing the assembly that suits the desired plug, threading the screws of subjection in the internal walls of said cavities.
Para ello, se prevé el suministro de las cajas descritas en estado desmontando, en forma de un conjunto de piezas que incluya la base (1) y tapa (2) así como, al menos, una pieza acoplable mecánicamente a la tapa y que comprenda un conjunto de cavidades para atornillado de múltiples enchufes.For this, the supply of the boxes is expected described in disassembly state, in the form of a set of parts that includes the base (1) and cover (2) as well as at least one piece mechanically attachable to the lid and comprising a set of Cavities for screwing multiple plugs.
