Definitions

  • the present invention relates to an industrial inline electrical socket/plug.
  • Inline plugs and sockets can be connected to the end of an electrical cable and are usually constituted by two parts: a plug-in component and a grip.
  • the cable is inserted in the grip and the terminals of the conductors are fixed to the electrical terminals of the plug-in component.
  • the grip and the plug-in component are simply connected by means of screws.
  • the assemblying operation is facilitated by providing a bayonet coupling between the grip and the plug-in component.
  • WO-97/36347 which is considered as being the closest prior art, discloses a connector plug for the electrical connection between a touring vehicle and a trail, comprising a housing constituted by a casing and a protective cap.
  • DE-4429780 discloses a two piece casing having a contact carrier.
  • the aim of the present invention is to provide an industrial inline electrical socket/plug which is improved with respect to the cited prior art.
  • An important object of the present invention is to provide an industrial inline electrical socket/plug which effectively and simply insulates the region of the electrical connections from the outside.
  • Another object of the present invention is to provide an industrial inline electrical socket/plug which is constructively simple and reliable in use and can be manufactured at competitive costs.
  • the industrial inline electrical socket and the corresponding plug respectively designated by the reference numerals 1 and 101, comprise a casing 30, 130 which includes a grip 2, 102 and a neck 3, 103, at the front.
  • the neck 3, 103 surrounds a removable plug-in component 4,104.
  • the grip portion 2, 102 and the protective neck 3, 103 are formed monolithically and constitute the casings 30 and 130 respectively.
  • the casings 30 and 130 differ in the dimensions of the respective necks 3 and 103.
  • the neck 103 of the plug must in fact be inserted, sliding along the neck 3 of the socket, upon connection.
  • the standards prescribe that the neck 3 must form a slot 5 adapted to receive a corresponding ridge 105 provided on the neck 103.
  • the socket includes a hinged cover 6 which is kept in the closed position by a spring when the socket is not engaged by a plug.
  • the plug-in components 4 and 104 differ only in the presence of bushes in one and of pins in the other.
  • the casing 30 has a threaded region 7 which is adapted to receive, and nondetachably retain, a ring 8 which actuates the cable locking system, which is described hereinafter.
  • the internal surface of the grip body 2 has guiding protrusions 9 which allow insertion and locking in the active position of the plug-in component 4, as described in greater detail hereinafter.
  • the plug-in component 4 is constituted by a cylindrical body in which there are channels for accommodating bushes suitable to receive pins. The bushes end with blades 10, between which the electrical cables are inserted while they are still sheathed in their insulation, passing through slots 11 provided in a rear wall 12 of the plug-in component 4.
  • the levers 13 have a recess 16 in which the end of the electrical cable, that passes through the slot 11, is arranged.
  • a protruding profile 35, formed on the lever 13 ensures mechanical locking with the body of the plug-in component when the levers are closed, engaging elastically against the rear wall 12 of the plug-in component 4.
  • the levers 13 can be opened by acting with a tool in a hole 36 which is provided laterally with respect to the lever so as to turn outward the lever 13 until the protruding profile 35 disengages from the rear wall 12.
  • the plug-in component 4 can be inserted in the casing 30. Once the electrical connections have been provided, the plug-in component 4 is placed inside the casing 30, making it slide axially until orientated radial fins 17 fit between the guiding protrusions 9, which form a single access channel, and rest on them, as shown more clearly in Figures 6 and 7.
  • a seat 18 is formed in the front wall of the plug-in component 4, between the bushes or the pins, and a tool, for example a conventional screwdriver, can engage therein.
  • a tool for example a conventional screwdriver
  • the radial fins 17 further form a flexible retention tooth 37 which at the end of the rotation engages the guiding protrusions 9, locking the plug-in component 4 and thus providing a bayonet coupling.
  • the plug-in component 4 In order to disengage the parts, it is sufficient to insert a tool along a cavity formed between the internal surface of the casing 30 and a slot 38 provided in the plug-in component 4 along the directrix of the tooth 37, so as to apply a pressure to the retention tooth, disengaging it from the guiding protrusions 9. To release the parts, it is then sufficient to turn the plug-in component 4 in the opposite direction. Once the plug-in component 4 has been engaged in the casing 30, the cable is locked by screwing on the ring 8.
  • the ring 8 has a thread 19 by way of which it couples to the thread 7 provided in the rear part of the grip body 2.
  • the ring 8 is of the nondetachable type and is adapted to lock, by means of an annular surface 20, a gasket member 21 which has an annular slot 22 adapted to engage the outer annular edge of a locking member 23 provided with flexible teeth 24.
  • the gasket member 21 has a cylindrical wall 39 which is arranged between the locking member 23 and the cable 40, so that the teeth 24 close onto the cable 40, guided by an annular protrusion 25 which is perpendicular to the internal surface of the casing 30 and forms a narrow opening.
  • This fixing system prevents relative movements between the cable and the casing 30, and the gasket member 21, which is made of flexible material, ensures the seal between the cable 40 and the edge 26 of the central opening of the gasket member.
  • the cable locking system is reversible by simply unscrewing the ring 8.
  • An advantage of the electrical socket/plug according to the present invention is the fact that wiring is extremely quick and easy.
  • a further advantage of the electrical socket/plug according to the present invention is that a cable fixing system is provided which prevents relative movements between the cable and the grip, preventing the accidental disengagement of the plug-in component while ensuring insulation of the plug-in component.
  • a further advantage of the electrical socket/plug according to the present invention is that it has a particularly simple final assembly.
  • the materials used, as well as the dimensions, may of course be any according to requirements and to the state of the art.
