DESCRIZIONE DESCRIPTION
Descrizione dell invenzione avente per TITOLO: †̃"Struttura fermacavi basculante auto adattabile†, Description of the invention having as TITLE: â € ̃ "Self-adaptable tilting cable clamp structureâ €,
DESCRIZIONE DESCRIPTION
Oggetto del presente trovato à ̈ un struttura fermacavi in grado di mantenere meccanicamente bloccati una coppia di cavi al dispositivo a cui i cavi stessi sono elettricamente collegati, Vari modelli di fermacavi sono stati proposti, nel caso in cui il problema si riduce al serraggio di un solo diametro di cavo non ci sono problemi particolari, le difficoltà nascono quando si devono ritenere in modo meccanicamente sicuro due cavi aventi diametri sensibilmente differenti. The subject of the present invention is a cable clamp structure able to mechanically keep a pair of cables locked to the device to which the cables are electrically connected. Various models of cable clamps have been proposed, in the case in which the problem is reduced to the tightening of a cable diameter only there are no particular problems, difficulties arise when two cables having significantly different diameters must be held in a mechanically safe way.
Il caso tipico à ̈ quello di un alimentatore per illuminotecnica in cui si ha un ingresso collegato alla rete elettrica di alimentazione e un uscita collegata alle lampade alimentate, i due cavi possono assumere forme e diametri notevolmente diversi, questo ha portato i costruttori all’utilizzo dì due fermacavt indipendenti, ognuno previsto del proprio sistema di bloccaggio, tipicamente una o due viti per fermacavo. The typical case is that of a power supply for lighting technology in which there is an input connected to the power supply network and an output connected to the powered lamps, the two cables can take on considerably different shapes and diameters, this has led manufacturers to use of two independent cable clamps, each provided with its own locking system, typically one or two screws per cable clamp.
Il nuovo sistema fermacavi oggetto del presente trovato utilizza una sola vite, à ̈ in grado di bloccare ad una base due cavi con diametri notevolmente differenti tra loro, il rapporto tra il diametro dei due cavi può essere maggiore di due, ed ha la proprietà di adattarsi automaticamente ai differenti diametri dei cavi durante l'avvitatura dellunica vite prevista. The new cable fastening system object of the present invention uses a single screw, is able to lock two cables with significantly different diameters to a base, the ratio between the diameter of the two cables can be greater than two, and has the property of automatically adapt to the different diameters of the cables when tightening the only foreseen screw.
Un esempio di prima realizzazione à ̈ visibile nella figura 1. An example of a first implementation can be seen in figure 1.
La struttura fermacavi si compone di due parti fondamentali: una parte fìssa detta base (2), preferibilmente coincidente con la base del contenitore utilizzato per il dispositivo a cui si The cable clamp structure consists of two fundamental parts: a fixed part called base (2), preferably coinciding with the base of the container used for the device to which it is
DESCRIZIONE DESCRIPTION
collegano i cavi e una parte mobile (1) che ha il compito di pressare i cavi contro la base bloccandoli. they connect the cables and a movable part (1) which has the task of pressing the cables against the base and locking them.
Sia la parte fissa che la parte mobile hanno una struttura rigida, non à ̈ prevista la loro deformazione elastica per adattarsi al diametro del cavo come accade in alcuni tipi di fermacavi, in modo da aumentare la stabilità meccanica e la forza di serraggio dei cavi. Both the fixed part and the mobile part have a rigid structure, their elastic deformation is not foreseen to adapt to the diameter of the cable as happens in some types of cable clamps, in order to increase the mechanical stability and the clamping force of the cables.
Avvitando la vite (3) sulla sede prevista per l’inserimento della vite (7) la parte mobile (1 ) si avvicina ai cavi (6,8) bloccandoli alla base (2). By screwing the screw (3) into the seat provided for the insertion of the screw (7), the mobile part (1) approaches the cables (6,8) locking them to the base (2).
La sede (7) per l’avvitamento della vite (3) à ̈ stampata in unico pezzo assieme alla base (2) a cui à ̈ solidale. The seat (7) for screwing the screw (3) is molded in one piece together with the base (2) to which it is integral.
La parte mobile, di cui la figura 2 rappresenta un primo esempio di realizzazione, Ã ̈ caratterizzata dalla presenza di un foro a forma asolata (10) per il passaggio della vite di fissaggio (3), The movable part, of which figure 2 represents a first example of realization, is characterized by the presence of a slotted hole (10) for the passage of the fixing screw (3),
La sezione della superficie (11) sottostante la testa della vite di fissaggio (3) à ̈ caratterizzata dall’avere una forma convessa, questa caratteristica unita alla forma asolata del foro (10) per la vite di fissaggio consente al fermacavi di scorrere liberamente sotto alla testa della vite inserita nel foro (10), in tal modo la parte mobile può oscillare liberamente attorno ad una asse perpendicolare a quello della vite e si ottiene una sorprendente capacità di adattamento a cavi di diametro differente senza diminuire la forza di serraggio applicata al cavo di diametro più piccolo (6), che rimane saldamente fissato alla base come quello di diametro più grosso (8). The section of the surface (11) below the head of the fixing screw (3) is characterized by having a convex shape, this feature combined with the slotted shape of the hole (10) for the fixing screw allows the cable clamp to slide freely under the head of the screw inserted in the hole (10), in this way the movable part can freely oscillate around an axis perpendicular to that of the screw and a surprising ability to adapt to cables of different diameters is obtained without decreasing the clamping force applied to the cable with a smaller diameter (6), which remains firmly fixed to the base like the one with a larger diameter (8).
La parte mobile viene mantenuta in posizione da due guide laterali (4,5) che si inseriscono nelle due aperture (9,12) predisposte nella parte mobile stessa. The movable part is kept in position by two lateral guides (4,5) which are inserted into the two openings (9,12) provided in the movable part itself.
La figura 4 mostra come le guide (18,19) tengono in posizione la parte mobile (21), impedendo che la stessa ruoti assieme alla vite (20) attorno all’asse di rotazione della vite stessa, quando la vite (20) viene avvitata per bloccare i cavi (17,22). Figure 4 shows how the guides (18,19) hold the mobile part (21) in position, preventing it from rotating together with the screw (20) around the rotation axis of the screw itself, when the screw (20) it is screwed to lock the cables (17,22).
DESCRIZIONE DESCRIPTION
La figura 3 evidenzia le zigrinature (13,14,15,16) poste sulla parte mobile a contatto con i cavi, tali zigrinature servono per aumentare l’adesione della superfìcie della parte mobile ai cavi sottostanti, aumentando la capacità di ritenuta, zigrinature analoghe (26,27) possono essere poste sulla base, come evidenziato nella sezione di figura 5. Figure 3 highlights the knurls (13,14,15,16) placed on the movable part in contact with the cables, these knurls are used to increase the adhesion of the surface of the movable part to the underlying cables, increasing the holding capacity , similar knurls (26,27) can be placed on the base, as shown in the section of figure 5.
Le zigrinature (26,27) poste sulla base possono anche sostituire quelle presenti sulla parte mobile. Altro elemento caratteri zzante à ̈ la mancanza di contatto tra la parte interiore (24) delia parte mobile e la parte superiore (23) della sede per il fissaggio della vile come visibile nella sezione di figura 5, avvitando la vite (25) nella sua sede la parte mobile non viene a contatto con la parte superiore (23) della sede di fissaggio della vite, in questo modo la forza di serraggio applicata dalia vite si trasferisce unicamente ai cavi sottostanti, la parte mobile si comporta come una leva adattandosi completamente ai cavi sottostanti. The knurls (26,27) placed on the base can also replace those present on the mobile part. Another characterizing element is the lack of contact between the inner part (24) of the mobile part and the upper part (23) of the seat for fixing the vile as shown in the section of figure 5, by screwing the screw (25) into its seat the moving part does not come into contact with the upper part (23) of the screw fixing seat, in this way the clamping force applied by the screw is transferred only to the underlying cables, the moving part behaves like a lever adapting completely to the cables underneath.
