Definitions

  • This patent concerns plugs, sockets and similar, and in particular flexible devices for locking electrical cables to the contacts of said plugs, sockets and similar.
  • the electrical cables consist of an outer insulating sheath made of flexible plastic material wrapped around one or more copper electric wires, each of which in its turn is coated by a flexible plastic insulating sheath.
  • the plugs, sockets and similar are provided internally with suitable retainers to each of which one of the electrical cable wires is connected.
  • the end of the electrical cable is without outer sheath so that the wires are independent; the latter, in their turn, are stripped of their sheath at the ends so that they can be mechanically and electrically connected to each electrical contact.
  • Terminals consisting of a body with hole and right-angle screw, for connection of the cable to the electrical contact.
  • the stripped cable is inserted into the hole and fastened by tightening the screw which presses the cable wires against the terminal hole wall.
  • terminals have various disadvantages: the screw must be fastened by exerting a certain pressure; if the screw is not sufficiently tightened, the cable wires may come out of the terminal with consequent overheating; if the screw is overtightened, the cable wires may be cut by the torsion-pressure of said tightening screw.
  • an elastic element consisting of a metal band in a roughly triangular shape, preferably a right-angled triangle: on one of the sides of the triangular shape, subsequently called mobile side, the metal band has a window or rectangular hole while the adjacent side, subsequently called adhesion side, has a tapered or narrower end so that it can pass through said window or rectangular hole.
  • the electrical contact also comprises a plate on which said roughly triangular-shaped elastic element is applied so that the adhesion side of the elastic element adheres to said plate of the electrical contact and so that both said adhesion side of the elastic element and said wall or plate of the electrical contact cross the window or hole of the side of the elastic element.
  • the third side of the elastic element subsequently called flexion side, is shaped so that it can be bent and bring said flexion side of the elastic element closer to the tapered side and to the plate of the electrical contact. In this way the window or rectangular hole of the elastic element is shifted and opens on the side of the electrical contact plate opposite the elastic element.
  • said elastic element By inserting the cable in the window or rectangular hole, thus opened, of the elastic element, said elastic element keeps said cable pressed on the wall or plate of the electrical contact.
  • the current sockets, plugs and similar provided with elastic element for locking the cable to the electrical contact are also provided with a mechanism for flexion of the elastic element comprising a cursor for flexion-opening of the elastic element.
  • Said cursor has a roughly linear shape with a channel on one side and a crack or recess at one end.
  • the comer between the mobile side and the flexion side of the elastic element locates in the cursor groove.
  • the linear translation of the cursor bends the flexion side of the elastic element, shifting the window or rectangular hole to the opposite side of the electrical contact plate.
  • the cursor is moved by inserting a screwdriver or other tool in the crack or recess at its top end.
  • the cursor mechanism for opening the elastic element has various disadvantages.
  • Axial operation of the cursor can cause partial or total detachment of the wire.
  • the socket or plug or similar must be somehow retained, with one hand gripping the screwdriver and pulling the cursor and the other hand inserting the cable, in the opposite direction to the pulling force of the screwdriver, into the window or rectangular hole of the elastic element; the cursor is then released and returns to the rest position due to the effect of the elastic element.
  • This operation is particularly inconvenient as the socket or plug has to be retained somehow until the cable is inserted.
  • the socket or plug has to be retained with one hand until the cursor is shifted and the cable can be taken out.
  • the aim of the new opening mechanism is to facilitate opening of the cable locking elastic element.
  • a further aim of the new opening mechanism is to permit opening of the cable locking elastic element without having to pull or push in any way.
  • a further aim of the new opening mechanism is to keep the cable locking elastic element open without having to exert any force, either traction, pressure or torsion.
  • the new plug connector for flexible and rigid cables with rotary opening mechanism comprising a cylindrical pin provided with a channel or groove with increasing diameter, on the surface of which the elastic element rests.
  • said lateral channel or groove connects an area with minimum radius, roughly half of the radius of the cylindrical pin, to the lateral surface of the cylindrical pin on a perpendicular plane to the axis of the cylindrical pin.
  • Said cylindrical pin is housed in the socket, plug or similar beside the cable locking elastic element, so that its lateral groove or channel adheres to the comer between the mobile side and the flexible side of the elastic element.
  • Figures 1 and 2 show, respectively, a lateral view and a horizontal section of a contact (C) of the related elastic element (E) for locking the cable and of the cylindrical pin (A) of the new opening mechanism.
  • Figure 3 shows a section of a connector, in this example a socket connector, showing a contact (C) with the related plate (C1), an elastic element (E) for locking the cable and a cylindrical pin (A) of the new opening mechanism.
  • the contact (C) comprises a plate (C1) joining it to the cable.
  • the elastic element (E) consists of a metal lamina roughly triangular-shaped, generally a right-angled triangle, one side of which, called adhesion side (E1), has a narrower end (E11), a second side, called mobile side or side moving at right angles (E2) featuring a window (E21) or rectangular hole, and a third side (E3), called flexion side, shaped to permit the movement of said mobile side (E2).
  • the elastic element (E) is joined to the plate (C1) of the electrical contact (C) so that the adhesion part (E1) of the elastic element (E) adheres to the plate (C1) of the electrical contact (C) and so that the narrower end (E11) and the end of the plate (C1) of the electrical contact are housed in the window or hole (E21) of the mobile wall (E2) of the elastic element (E).
  • the cylindrical pin (A) of the new opening mechanism has a generally cylindrical shape, features a groove or channel (A1) on the lateral surface and is provided at the top with a slot (A2).
  • the upper slot (A2) is designed to receive the tip of a screwdriver thus permitting the rotation of said cylindrical pin (A).
  • the lateral groove or channel (A1) of the cylindrical pin (A) has a roughly spiral portion shaped section, connecting a portion near the axis of the cylindrical pin (A) to the lateral surface of the cylindrical pin (A) on a plane perpendicular to the axis of the cylindrical pin (A).
  • the cylindrical pin (A) is housed in the socket or plug so that its channel or groove (A1) rests on the comer of the elastic element (E) common to the mobile side (E2) and the flexion side (E3).
  • Said cylindrical pin (A) and/or its housing in the socket or plug can be provided with stop or stroke end elements designed to limit rotation of the cylindrical pin (A).
  • the window or circular hole (E21 ) of the elastic element (E) remains open, permitting insertion, removal, or repositioning of the cable with the greatest of ease. Subsequent rotation of the cylindrical pin (A) of the new opening mechanism in the opposite direction enables the elastic element (E) to return to the normal position in which it presses the cable on the wall (C1) of the electrical contact (C).
  • the opening mechanism of the elastic element (E) is accessible, even though located in depth and with other parts of the plug or socket around it and/or a protective edge.
