  • the present invention relates to a device for the electric interconnection of electric cables.
  • each electric cable without the relative insulating sheath, is inserted in a special housing of the relative terminal where, by means of a mechanical screw or spring system, the mechanical block is made of the electric cable while ensuring at the same time the closing of the relative electric circuit.
  • the terminals complete with screw tightening mechanism represent the most common connection method wherein the electric cable unsheathed of the insulation is fixed to the terminal by means of a screw.
  • the screw tightening and loosening operations are practical and easy and can be performed with the aid of a screwdriver or the like.
  • the use is known of devices comprising a socket body adapted to house two or more male terminals, if necessary made in a monobloc socket module, and a plug body adapted to house two or more female terminals, these too made in a monobloc plug module.
  • the socket and plug modules are fixed to the respective socket and plug bodies by pressure fitting inside the bodies themselves which in turn are provided with means of fastening/release of such modules.
  • the fastening/release means of the socket and plug modules are made by means of hooks and have at least a portion associated with the external surface of the socket and plug bodies.
  • Such hooks have very little flexibility so as to ensure, as much as possible, the fastening resistance of the bodies in the event of strong stresses or tractions applied by external forces on the socket and plug bodies.

Furthermore, as can be easily appreciated from the illustrations, the fourth embodiment shows a structure substantially the same as the second embodiment with the difference in the fact that the arm element 31 is associated with the second coupling portion 14 and extends cantilevered towards the first plane 7.
  • the flange element 31 undergoes compression forces, thus resulting sturdier to deformations and/or breakages with respect to the arm element 31 in the first and the second embodiment.
  • the described invention achieves the intended objects and in particular the fact is underlined that the device made this way is very practical and easy to use by the operator during wiring and assembly operations, because once the cores of the electric cables have been connected to the respective terminals, the electric connection between the male and female terminals is achieved by simply inserting the plug body inside the socket body.
  • the particular embodiments of the manufactured device differ in terms of the fact that in the case of the first embodiment, the operator has to use particular pointed presser tools to release the plug body from the socket body, while in the case of the second embodiment the release of the plug body from the socket body can be obtained by anyone inasmuch as it is enough to apply a pressing force on the unhooking means.
  • the second embodiment of the device is therefore more practical to use than the first embodiment, notwithstanding the fact that the release mechanism between the socket body and the plug body is the same.
  • the particular orientation of the arm element results in the arm element itself being safe from damage and/or breakages due to accidental operations by the operator during the coupling of the plug body to the socket body.
  • the arm element in the third and fourth embodiments is sturdier against any deformations and consequent breakages, ensuring greater reliability in keeping the coupling between the plug body and the socket body and consequently of the electric connection of the relative electric cables.
