del BREVETTO PER MODELLO INDUSTRIALE DI UTILITÀ avente per titolo: PATENT FOR INDUSTRIAL UTILITY MODEL entitled:
"CORPO DI INTERRUTTORE CON PROTEZIONI CONTRO POLVERE "SWITCH BODY WITH PROTECTIONS AGAINST DUST
E SPRUZZI" AND SPRAYS "
Il presente trovato riguarda il settore degli interruttori elettrici unipolari o bipolari, di vario genere e di diverse dimensioni, e che trovano impiego in apparecchiature elettriche ed elettroniche nonché in elettrodomestici destinati ad operare in ambienti ad alto tasso di umidità e/o in presenza dì liquidi. The present invention relates to the sector of unipolar or bipolar electrical switches, of various kinds and of different sizes, and which are used in electrical and electronic equipment as well as in household appliances intended to operate in environments with high humidity and / or in the presence of liquids. .
Per rispondere a talune norme di sicurezza, tali interruttori elettrici devono godere di una protezione contro l'umidità, spruzzi d'acqua e pulviscolo ambientale.A tal fine, già è stato proposto di munire gli interruttori di protezione contro polveri ed umidità. Secondo la tecnica nota, dette protozìoni consistono in elementi riportati sottoforma di cappucci esterni e/o di accessori interni, come membrane, usualmente in un materiale elastomerico. Si tratta comunque di elementi aggiuntivi che devono avere forme obbligate e mezzi di fissaggio e che implicano costi di realizzazione, tempi ed oneri di montaggio. To comply with certain safety standards, these electrical switches must have protection against humidity, water sprays and environmental dust. To this end, it has already been proposed to provide the switches with protection against dust and humidity. According to the known art, said protocols consist of elements inserted in the form of external caps and / or internal accessories, such as membranes, usually in an elastomeric material. However, these are additional elements which must have obligatory forms and fixing means and which involve construction costs, assembly times and costs.
Scopo del presente trovato è di fornire un interruttore elettrico protetto contro polveri, umidità e spruzzi con dei mezzi di protezione integrati con il corpo di interruttore, più precisamente costampati con il corpo stesso. The object of the present invention is to provide an electric switch protected against dust, humidity and sprays with protection means integrated with the switch body, more precisely co-molded with the body itself.
Si hanno così i vantaggi di non dover produrre e montare elementi separati; di diminuire i costi di produzione; di avere libera scelta nelle forme e nell'estetica del manufatto; di garantire un grado di tenuta e di protezione comparabile, se non addirittura maggiore, con quello conseguito con gli elementi riportati più usuali per il rispetto delle norme vigenti in materia. This gives the advantages of not having to produce and assemble separate elements; to decrease production costs; to have free choice in the shapes and aesthetics of the product; to guarantee a degree of tightness and protection comparable, if not even greater, with that achieved with the most usual elements reported for compliance with the regulations in force on the subject.
Detto scopo e tali vantaggi sono conseguiti con un corpo di interruttore secondo la rivendicazione 1 e che sarà qui di seguito descritto in dettaglio, e a titolo di esempio, facendo riferimento agli allegati disegni nei quali: Said object and these advantages are achieved with a switch body according to claim 1 and which will be described in detail below, and by way of example, with reference to the attached drawings in which:
la Fig.l mostra, in sezione longitudinale, un interruttore a tasto basculante completo di protezioni secondo il trovato;e Fig. 1 shows, in longitudinal section, a rocker switch complete with protections according to the invention; and
la Fig.2 mostra una sezione trasversale dell'interruttore della Fig.l. Fig.2 shows a cross section of the circuit breaker of Fig.1.
L'interruttore illustrato ha un corpo 11 del tipo composto da una parte anteriore 12 e da una parte posteriore 13 complementari. La parte anteriore 12 è in un materiale rigido e presenta una flangia periferica frontale 12* ed una porzione interna 12" convergente al centro dove definisce un'apertura. The illustrated switch has a body 11 of the type composed of a complementary front part 12 and a rear part 13. The front part 12 is made of a rigid material and has a front peripheral flange 12 * and an internal portion 12 "converging in the center where it defines an opening.
La parte posteriore 13 del corpo, anch'essa rigida, ha una parete di fondo 13' portante dei contatti fissi 14 per almeno un circuito elettrico e presenta due alette di aggancio 13" da due lati opposti. The rear part 13 of the body, also rigid, has a bottom wall 13 'carrying fixed contacts 14 for at least one electrical circuit and has two hooking lugs 13 "on two opposite sides.
La parte anteriore 12 del corpo di interruttore porta un tasto di comando 15, basculante su un asse definito da perni 15' inseriti in alloggiamenti ricavati nei lati della parte stessa -v.Fig.2-. Il tasto ha un gambo 15", rigido o con una parte elastica, che passa nell'apertura definita dalla porzione interna 12" e che si estende fino ad un contatto mobile 16 rotante su un fulcro 16'. il contatto mobile ò comandato dal tasto per aprire e chiudere il o i circuiti che fanno capo ai contatti fìssi 14. The front part 12 of the switch body carries a control button 15, pivoting on an axis defined by pins 15 'inserted in housings obtained in the sides of the part itself - see Fig. 2-. The key has a shank 15 ", rigid or with an elastic part, which passes into the opening defined by the internal portion 12" and which extends up to a movable contact 16 rotating on a fulcrum 16 '. the movable contact is controlled by the key to open and close the circuit or circuits which refer to the fixed contacts 14.
In accordo al trovato, la faccia interna della flangia perimetrale frontale 12' reca una guarnizione 17 ottenuta in un materiale morbido di costampaggio con la parte anteriore del corpo. La guarnizione ha una forma adatta a garantire la tenuta contro polvere ed umidità tra la flangia frontale 12' ed un pannello 18 alla quale si aggancia l'interruttore per la sua messa in opera. In accordance with the invention, the internal face of the front perimeter flange 12 'has a gasket 17 obtained in a soft material co-molded with the front part of the body. The gasket has a shape suitable to guarantee the seal against dust and humidity between the front flange 12 'and a panel 18 to which the switch is attached for its installation.
Un'altra guarnizione 19, in materiale morbido, è prevista attorno al gambo 15" del tasto pressoché a livello dell 'asse di rotazione del tasto medesimo. Questa guarnizione 19 ò ottenuta dì costampaggio sulla porzione interna 12" in corrispondenza all'apertura da questa definita. Another gasket 19, made of soft material, is provided around the stem 15 "of the key almost at the level of the rotation axis of the key itself. This gasket 19 is obtained by co-molding on the internal portion 12" in correspondence with the opening therefrom. defined.
La guarnizione 19 aderisce al gambo 15" del tasto senza influire sui movimenti di questo, ma rendendo inaccessibile la camera interna che si viene a creare tra le parti anteriore e posteriore del corpo e proteggendo i contatti mobili e fìssi. The gasket 19 adheres to the shank 15 "of the key without affecting its movements, but making the internal chamber created between the front and rear parts of the body inaccessible and protecting the movable and fixed contacts.
In altri termini, le guarnizioni 17 e 19 ottenute di costampaggio con la parte anteriore del corpo di interruttore offrono una valida protezione contro l'ingresso dì polvere ed acqua dall'esterno, quando l'interruttore è in opera senza il riporto di alcun altro elemento. In other words, the gaskets 17 and 19 obtained by co-molding with the front part of the switch body offer valid protection against the ingress of dust and water from the outside, when the switch is in operation without the addition of any other element. .
La descrizione di cui sopra ò stata riferita ad un interruttore a tasto basculante ma le protezioni contro polvere e spruzzi sono applicabili ugualmente e con gli stessi vantaggi anche agli interruttori a pulsante e a slitta, senza uscire dall'ambito del trovato. The above description has been referred to a rocker switch but the protections against dust and splashes are equally applicable and with the same advantages also to push-button and slide switches, without departing from the scope of the invention.
