Definitions

  • This patent concerns trailing plugs and sockets and in particular the so-called industrial trailing plugs and sockets.
  • So-called industrial plugs and sockets are known, i.e. with cylindrical body with three or more contacts, female holes or male cylindrical terminals, arranged in a generally polygonal configuration and in different positions according to the sector of use.
  • Said plugs and sockets are provided with safety devices, covers to protect the female contacts, and groove or external longitudinal lug which acts as a key for correct coupling between the male and female elements.
  • the electrical contacts of said plugs and sockets have a different diameter, i.e. the phase and neutral have the same diameter, but the earth has a larger diameter.
  • the contacts are arranged in a polygon configuration, in which the earth constitutes the vertex.
  • Said plugs and sockets differ according to the sector of use - containers, refrigerators, commonly used trailing plugs-sockets, marine-naval installations - due to the position of the contacts with respect to the lug or groove which acts as a coupling key between plug and socket.
  • a new so-called industrial plug and socket with three or more poles has been designed and produced, having facilitated opening, safety and support eyelet, and shaped so that it can be rotated to any angle during assembly.
  • the aim of the new plug and socket is to ensure the angular positioning of the contacts with respect to the coupling key according to the sector of use, i.e. according to the socket or plug to be coupled.
  • a further aim of the new plug and socket is to permit said positioning of the contacts subsequently to moulding of the plug and socket element and before it is placed on the market.
  • a further aim of the new plug and socket is to allow all the positionable parts to be produced with one single set of moulds for all the possible positions.
  • a further aim of the new plug and socket is to ensure high levels of safety against short circuits, accidental contacts and similar.
  • the support of the contacts is provided on the perimeter with some radial lugs.
  • the shell that retains the support of the contacts on the body of the unit is provided internally with housings or recesses, preferably indicated by 12, corresponding to the various possible positions of the contacts and the support.
  • a closed eyelet, preferably positioned opposite the tooth or lug, guarantees a safe grip.
  • the release device comprises an elastic part which is released by means of a screwdriver or similar tool passing through a hole on the edge of the unit.
  • Figure 1 shows the separate parts of the new plug comprising a body (C) provided with safety clamp (M) to prevent the wires from sliding out, a support (S) of the contacts (Sc) and a fixing shell (G).
  • figure 1 corresponds to a plug but the following considerations apply equally to the corresponding socket, shown in figure 2.
  • the body (C) of the plug has a generically cylindrical shape with a tooth or lug (Cr) on one side, comprises at one end a safety ring nut (M) to prevent the wires from sliding out and at the other end a housing for the fixing ring nut (G) and in turn for the support (S) of the contacts (Sc1) (Sc2).
  • the support (S) of the contacts (Sc) consists of a generically cylindrical element, designed to be housed in the body (C) of the plug, on which parallel metal pins are fixed and/or applied which constitute the contacts (Sc) of the plug.
  • Said contact pins (Sc) are arranged on a the support according to a polygonal configuration, which is the typical arrangement of the contacts of industrial plugs and sockets, and are provided with appropriate clamps for fixing the electric wires.
  • one of said metal pins (Sc1) has a larger diameter and constitutes the earth contact.
  • the support (S) of the contacts (Sc) is provided, on its cylindrical lateral surface, with one or more longitudinal lugs (Sr), parallel to the axis of the support (S).
  • the support (S) consists of a cylindrical element (O) having three cylindrical cavities (Oc), as shown in figure 2, corresponding to the contacts (Sc) of the plug.
  • the shell (G) consists of a cylindrical element (G1) having at one end a housing for the support (S) provided with the related contacts (Sc).
  • said housing of the shell (G) is provided, along its circumference, with a series of recesses or grooves designed to receive the longitudinal lugs (Sr) of the support (S).
  • the number, preferably 12, and positions of said recesses are such as to permit application of the support (S) in the different positions depending on the various sectors of use of the plug.
  • the shell (G) is also provided, on the outer surface of the same end of the housing for the support (S), with arched lugs (G11) with circular sector, designed to permit coupling and fixing with corresponding housings (Cs) on the body (C) of the socket.
  • said shell (G) is provided with a flexible tooth (Gx), or equivalent flexible mechanical element, which can be bent on a plane parallel to the axis of the shell (G), designed to permit locking and release of the shell (G) on/from the body (C), as can be seen in figure 3c.
  • Gx flexible tooth
  • said shell (G) is provided with a flexible tooth (Gx), or equivalent flexible mechanical element, which can be bent on a plane parallel to the axis of the shell (G), designed to permit locking and release of the shell (G) on/from the body (C), as can be seen in figure 3c.
  • said flexible tooth (Gx) is arranged on the surface of the shell (G) so that, when the shell (G) is closed on the body (C) of the socket, said flexible tooth (Gx) fits into the housing (Cx) of the body (C) of the socket and is visible and accessible through the window or aperture (Ca) on the body (C) of the socket.
  • an eyelet or ring-shaped grip (Co) is provided to make it easier to hold the socket when joining it to or, more advantageously, separating it from the plug, or when hooking or hanging the plug-socket.
