An interlocked socket with modular automatic protection switch, characterized in that it comprises a front body (2) that is adapted to be applied to a panel (100) or other wall-mounted support; said front body (2) contains a support (4) which extends internally and comprises a holder member (5) shaped as a DIN guide; a modular switch (6) is attached to said holder member (5).
The present invention relates to an interlocked socket with modular automatic protection switch.
As is known, an interlocked socket incorporates a mechanical or electrical locking device, which is connected to an interruption system that does not allow the insertion or extraction of the plug when the socked is powered, i.e. in the presence of voltage.
Interlocked sockets equipped with magneto-thermal or residual current operated breakers are known.
In most conventional interlocked sockets, the modular switch is arranged at the bottom of the socket, and the front part and the bottom of the socket constitute a single assembly.
In case of intervention of the automatic protection switch, resetting is performed by using the knob of the interlocked socket that is connected to the means for the actuation of the switch by means of levers and gears. The levers and gears operate the handles of the modular switch.
The aim of the present invention is to provide an interlocked socket with modular automatic protection switch that can be easily integrated in an electrical panel.
Within the scope of this aim, an object of the invention is to provide an interlocked socket with modular automatic protection switch that is compact and can be wired more easily and quickly than the conventional interlocked sockets.
Another object of the present invention is to provide a socket with a structure which, by virtue of its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
This aim and these and other objects that will become better apparent hereinafter are achieved by an interlocked socket with modular automatic protection switch, characterized in that it comprises a front body adapted to be applied to a panel or other wall-mounted support; said front body contains a support which extends internally and comprises a holder member shaped as a DIN guide; a modular switch is attached to said holder member.
The modular switch is wired with a socket associated with the front body; the socket has a locking means, which prevents the insertion and disconnection of a plug when there is electrical voltage in the system; the locking means is actuated by a control knob by means of a lever system.
The knob transmits a rotary motion to the handles of the modular switch, by means of a gear lever system, which has a pivot that passes within the modular switch, connecting the various handles of the switch.
Further characteristics and advantages will become better apparent from the description of preferred but not exclusive embodiments of the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:
With reference to the cited figures, an interlocked socket with modular automatic protection switch according to the invention, generally designated by the reference numeral 1, comprises a front body 2 which is adapted to be applied to a panel 100 or other wall-mounted support where one intends to apply the interlocked socket.
The front body 2 contains a support 4 which extends internally and comprises a holder member 5.
The holder member 5 is shaped as a DIN guide.
A modular switch 6, for example a series of magneto-thermal poles, each associated with a pole of the socket, is attached to the holder member 5.
Preferably, the support 4 is made of technopolymer.
The modular switch 6 is wired to a socket 7 associated with the front body 2.
The socket 7 comprises a locking means which prevents the insertion and disconnection of a plug, when the system is powered, in a per se known manner.
The locking means is actuated by a control knob 8 by means of a lever system.
The rotary motion provided by the knob 8 is transmitted by means of a gear lever system, generally designated by the reference numeral 9, which ends with a metallic pivot 10 that passes within the modular switch 6, connecting the various handles 11 of the switch.
The interlocked socket forms a single unit with the modular switch 6, which is jointly connected to the front body 2 of the socket and can thus be mounted on a panel 100, for example a so called Q DIN panel.
In practice it has been found that the invention achieves the intended aim and objects, an interlocked socket having been provided which, differently from conventional interlocked sockets, has the modular switch associated directly with the front body and therefore does not require a separate support or a base for the switch.
The interlocked socket according to the present invention is quicker and easier to install, because it is sufficient to connect the power supply cables that arrive from the panel to the modular switch, which is already wired with the socket in the front.
The knob 8 controls the handles of the modular switch by means of a metallic pivot 10 that passes within the modular switch itself.
