Description
- The present invention refers to an adapter device for industrial electrical sockets particularly but not exclusively useful in the field of industrial electrical engineering.
- Currently, numerous electrical sockets/plugs are known that differ not only due to the different use for which they are intended, but also for the different electrical standards to be respected in the countries where they are intended to be installed.
- In any case, there are known so-called civil electrical plugs/sockets that are usually associated with the electrical power supply of commonly-used or domestic tools like, for example, drills, hammers, angle grinders and so on. A very common type of civil plug/socket is, for example, a "schuko" type plug/socket complying with European standard CEE 7/7. So-called industrial electrical plugs/sockets are also known that can be monophase or triphase and are able to support the greater electrical currents that are usually used in industry to supply machinery, furnaces and so on. Industrial electrical plugs/sockets are also made to operate safely in difficult environmental conditions (outdoors, exposed to water, ice, sand and various chemical agents), to have greater mechanical strength and to prevent accidental disconnections. A very common type of industrial plug/socket is, for example, a plug/socket complying with European standard IEC 309.
- In common use, however, it may be necessary to use tools supplied through civil electrical plugs where only industrial electrical sockets are installed, like for example on building sites or in industrial settings.
- In these cases, it is known to cut the power supply cable of the aforementioned tools upstream of the civil electrical plug and connect the relative conductors of the cable to an industrial electrical plug. In this way, however, the guarantee against failure and/or manufacturing defects associated with the tools that have been tampered with is lost.
- For this reason, it is usual to use adapter devices capable of adapting a civil electrical socket to an industrial one. These known adapter devices are arranged at the front to be engaged in industrial electrical sockets and at the rear to couple with civil electrical plugs.
- In particular, the adapter devices currently known comprise a plug body that at the front carries a plurality of pins suitable for being engaged in an industrial electrical socket and on the back carries a plurality of connectors suitable for coupling with a civil electrical plug. These connectors are in turn enclosed in a protective shell applied onto the back of the plug body so as to make an actual civil electrical socket.
- This shell, however, offers a degree of protection against the penetration of dangerous external agents like water, which may not be considered sufficient by the safety control authorities on worksites, in factories and so on.
- Indeed, the protective shell generally mounted on the known adapter devices is able to externally cover the connection interface between the connectors and the civil electrical plug and only partially the plug itself.
- It is therefore possible that in critical conditions, like for example in the case of outdoor installations, water can penetrate into the adapter device through the rear civil electrical socket with a consequent risk of electrical dispersions, electrocution and damages to the apparatus connected.
- The purpose of the present invention is to avoid the aforementioned drawbacks and, in particular, to devise an adapter device for industrial sockets that allows a civil electrical plug to be supplied with power with an industrial electrical socket ensuring a greater degree of mechanical protection and protection against external agents with respect to known adapter devices. These and other purposes according to the present invention are accomplished by making an adapter device for industrial sockets as outlined in claim 1.
- Further characteristics of the adapter device for industrial sockets are the object of the dependent claims.
- The characteristics and advantages of an adapter device for industrial sockets according to the present invention will become clearer from the following description, given as a non-limiting example, referring to the attached schematic drawings, in which:
-

pins 21 and theinsulating casing 22 that carriessuch pins 21 and that is connected to an end of anelectrical cable 23. In particular, such an expression refers to any civil electrical plug, conforming to any national standard. - The
connectors 13 are designed to adapt the industrial electrical socket for the aforementioned civilelectrical plug 20;such connectors 13 are therefore connected to the front pins. - The
adapter device 10 also comprises aprotective shell 14 of theconnectors 13 coupled with the back of theplug body 11. - Such a coupling can for example be obtained through interlocking and/or using fixing means like, for example, screws.

protective shell 14 extends behind theplug body 11 in the longitudinal direction for a length portion such as to completely cover theconnectors 13 and the civilelectrical plug 20 when it is engaged in theconnectors 13. - In the present description, by longitudinal direction we mean the direction of extension in length of the civil
electrical plug 20 when it is engaged in theconnectors 13. Therefore, in the case in which theconnectors 13 are oriented so that the civilelectrical plug 20 engaged extends in length in a direction perpendicular to thepins 12, such a direction will correspond to the direction of longitudinal extension of theprotective shell 14. - In the particular illustrated embodiment of the present invention, the

openings 31 that, when the half-shells are in constraint position, form acircular opening 19 of diameter such that the cable of the civil electrical plug is flush with the edge of theopening 19 when the plug itself is engaged in theadapter device 10. More generally, the opening 19 and the half-openings 31 can be of any shape and size. - In an embodiment that is not illustrated of the present invention, the half-
shells shells shell 18 is arranged on the base half-shell 17. Preferably, theplug body 11 is equipped at the back with fasteningportions 15 that project outwards and theprotective shell 14 is internally provided withcorresponding coupling recesses 16 in which theaforementioned coupling portions 15 joint engage in a firm manner making the coupling between theprotective shell 14 and theplug body 11. - In addition, one of the two half-
shells fixing seats 32; in a corresponding position, the other half-shell comprises throughholes 33 through which it is possible to insertfixing means 34, like for example screws, which engage in thefixing seats 32 in order to make the constraint between the two half-shells shell 17 comprises thefixing seats 32 whereas the covering half-shell 18 comprises the corresponding throughholes 33. - In a first embodiment of the present invention, each of the half-
shells wall 35 that extends transversally to the direction of extension of theprotective shell 14 so that, when the two half-shells walls 35 are opposite one on the other to form a transversal separating wall. - Each half-
wall 35 defines a first half-chamber 36 and a second half-chamber 37 inside each half-shell. Thus, when the two half-shells walls 35 defines a first and a second chamber for at least partially housing, respectively, theconnectors 13 and the civilelectrical plug 20, where such housing chambers are defined by the joining of the half-chambers - The half-
walls 35, moreover, are shaped so as to define, on the resulting transversal wall, a plurality of openings (not illustrated) at theconnectors 13 to allow the engagement of thepins 21 of the civilelectrical plug 20 in theconnectors 21. In particular, as can be seen for example infigure 1a , the half-wall 35 of the base half-shell 17 comprises tworecesses 38 on top; in a corresponding position the half-wall (not illustrated) of the covering half-shell 18 also comprises two recesses (not illustrated) that, when the half-shells are in constraint position, form - with therecesses 38 of the base half-shell 17 - the through openings for thepins 21 of the civilelectrical plug 20. - In a second embodiment of the present invention, one of the half-
shells connectors 13 and the civilelectrical plug 20, and comprises a plurality of openings, preferably through holes, at theconnectors 13 to allow the engagement of thepins 21 of the civilelectrical plug 20 in theconnectors 13. - In any case, the base half-
shell 17 preferably internally comprises, at the opposite end to that for coupling with theplug body 11, a receiving and guidingseat 39 for thecable 23 of the civilelectrical plug 20 laterally provided withengagement seats 40 for fixing means. In this case, theadapter device 10 also comprises alocking plate 41 suitable for being constrained to the receiving and guidingseat 39 through fixing means so as to hold thecable 23 of the civilelectrical plug 20 in such a receiving and guidingseat 39. - Preferably, the
protective shell 14 comprises aseal gasket 42 at the through opening 19 for thecable 23 of the civilelectrical plug 20. - Preferably, the plurality of
connectors 13 comprises a corresponding plurality ofclamps 13 configured to clamp thepins 21 of the civilelectrical plug 20 through respective fixing screws. - In the case in which the civil
electrical plug 20 is of the type complying with European standard CEE 7/7, theplug body 11 is also provided at the back with two flexiblemetallic tabs 43 intended to come into contact with the protective conductor provided onsuch plugs 20. - In this case, the half-
walls 35 have, in a position corresponding to theflexible tabs 43 someslits 44. Indeed, in particular, suchflexible tabs 43 extend in the longitudinal direction so as to pass, when the half-shells slits 44. - From the description that has been made the characteristics of the adapter device for industrial electrical sockets object of the present invention are clear, just as the relative advantages are clear. Indeed, the protective shell is able to shield the civil electrical plug from water and other foreign bodies when it is engaged in the adapter device, ensuring the high degree of protection that needs to be maintained when connecting to an industrial electrical socket. In particular, the aforementioned protective shell ensures a degree of protection at least equal to the IP44 rating defined by standard UNI EN60529 or CEI 70-1.
- The risk of penetration of water is further reduced thanks to the presence of the rear opening of the protective shell sized so as to allow the cable of the civil electrical plug that is to be engaged to pass flush. The presence of a seal gasket at the aforementioned opening further increases the degree of safety and impermeability of the volume enclosed by the protective shell.
- Finally, it is clear that the adapter device for industrial electrical sockets thus conceived can undergo numerous modifications and variants, all of which are covered by the invention; moreover, all of the details can be replaced by technically equivalent elements. In practice, the materials used, as well as the sizes, can be whatever according to the technical requirements.
