Definitions

  • the present invention refers to an adapter device for industrial electrical sockets particularly but not exclusively useful in the field of industrial electrical engineering.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • an adapter device for industrial electrical sockets is shown, wholly indicated with 10.
  • Such an adapter device 10 comprises a plug body 11 provided at the front with a plurality of pins 12 suitable for being engaged in an industrial electrical socket (not illustrated) and at the back with a plurality of connectors 13 suitable for receiving corresponding pins 21 of a civil electrical plug 20.
  • civil electrical plug 20 refers to the assembly comprising both the pins 21 and the insulating casing 22 that carries such pins 21 and that is connected to an end of an electrical cable 23.
  • civil electrical plug 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 civil electrical plug 20; such connectors 13 are therefore connected to the front pins.
  • the adapter device 10 also comprises a protective shell 14 of the connectors 13 coupled with the back of the plug body 11.
  • Such a coupling can for example be obtained through interlocking and/or using fixing means like, for example, screws.
  • the protective shell 14 extends behind the plug body 11 in the longitudinal direction for a length portion such as to completely cover the connectors 13 and the civil electrical plug 20 when it is engaged in the connectors 13.
  • longitudinal direction we mean the direction of extension in length of the civil electrical plug 20 when it is engaged in the connectors 13. Therefore, in the case in which the connectors 13 are oriented so that the civil electrical plug 20 engaged extends in length in a direction perpendicular to the pins 12, such a direction will correspond to the direction of longitudinal extension of the protective shell 14.
  • the protective shell 14 comprises a base half-shell 17 and a covering half-shell 18 suitable for being reversibly constrained one on the other in a constraint position to define the protective shell 14; such half-shells 17, 18 are, moreover, shaped so that the protective shell 14, at the opposite end to that for coupling with the plug body 11, has an opening 19 for the passage of the electrical cable 23 that carries the civil electrical plug 20.
  • the two half-shells have two semi-circular half-openings 31 that, when the half-shells are in constraint position, form a circular opening 19 of diameter such that the cable of the civil electrical plug is flush with the edge of the opening 19 when the plug itself is engaged in the adapter device 10.
  • the opening 19 and the half-openings 31 can be of any shape and size.
  • the half-shells 17 and 18 are coupled at one of the two longitudinal sides so as to be able to pass reversibly from an opening position in which the half-shells 17 and 18 are arranged side by side to each other and a closing position in which the covering half-shell 18 is arranged on the base half-shell 17.
  • the plug body 11 is equipped at the back with fastening portions 15 that project outwards and the protective shell 14 is internally provided with corresponding coupling recesses 16 in which the aforementioned coupling portions 15 joint engage in a firm manner making the coupling between the protective shell 14 and the plug body 11.
  • one of the two half-shells 17, 18, comprises a plurality of fixing seats 32; in a corresponding position, the other half-shell comprises through holes 33 through which it is possible to insert fixing means 34, like for example screws, which engage in the fixing seats 32 in order to make the constraint between the two half-shells 17, 18 stable.
  • the base half-shell 17 comprises the fixing seats 32 whereas the covering half-shell 18 comprises the corresponding through holes 33.
  • each of the half-shells 17, 18 comprises a half-wall 35 that extends transversally to the direction of extension of the protective shell 14 so that, when the two half-shells 17, 18 are in constraint position, the half-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.
  • the transversal wall resulting from the juxtaposition of the two half-walls 35 defines a first and a second chamber for at least partially housing, respectively, the connectors 13 and the civil electrical plug 20, where such housing chambers are defined by the joining of the half-chambers 36, 37 of each half-shell.
  • the half-walls 35 are shaped so as to define, on the resulting transversal wall, a plurality of openings (not illustrated) at the connectors 13 to allow the engagement of the pins 21 of the civil electrical plug 20 in the connectors 21.
  • the half-wall 35 of the base half-shell 17 comprises two recesses 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 the recesses 38 of the base half-shell 17 - the through openings for the pins 21 of the civil electrical plug 20.
  • one of the half-shells 17, 18 internally comprises a transversal separating wall (not illustrated) with respect to the direction of longitudinal extension of the protective shell; such a separating wall, when the half-shells are in constraint position, defines a first and a second chamber (not illustrated) for at least partially housing, respectively, the connectors 13 and the civil electrical plug 20, and comprises a plurality of openings, preferably through holes, at the connectors 13 to allow the engagement of the pins 21 of the civil electrical plug 20 in the connectors 13.
  • the base half-shell 17 preferably internally comprises, at the opposite end to that for coupling with the plug body 11, a receiving and guiding seat 39 for the cable 23 of the civil electrical plug 20 laterally provided with engagement seats 40 for fixing means.
  • the adapter device 10 also comprises a locking plate 41 suitable for being constrained to the receiving and guiding seat 39 through fixing means so as to hold the cable 23 of the civil electrical plug 20 in such a receiving and guiding seat 39.
  • the protective shell 14 comprises a seal gasket 42 at the through opening 19 for the cable 23 of the civil electrical plug 20.
  • the plurality of connectors 13 comprises a corresponding plurality of clamps 13 configured to clamp the pins 21 of the civil electrical plug 20 through respective fixing screws.
  • the plug body 11 is also provided at the back with two flexible metallic tabs 43 intended to come into contact with the protective conductor provided on such plugs 20.
  • the half-walls 35 have, in a position corresponding to the flexible tabs 43 some slits 44.
  • such flexible tabs 43 extend in the longitudinal direction so as to pass, when the half-shells 17 and 18 are in constraint position, from the first to the second housing chamber, passing through the transversal separating wall at the slits 44.
  • 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.
  • 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.
