Definitions

  • the present invention refers to an electric connection device.
  • the invention refers to an electric connection device, comprising two connection elements capable of being mutually coupled through a bayonet-type locking mechanism and through a secondary locking mechanism configured for preventing an accidental disconnection of the two connection elements, further comprising a removable unlocking mechanism.
  • Electric connection devices are known, for example from US5685730 , comprising two connection elements, configured to be blocked through a bayonet-type locking mechanism which provides that the two elements are pressed one towards the other and blocked following the rotation of one related to the other, further comprising a secondary locking mechanism of said connection elements, having a spring-loaded safety pin which prevents the mutual rotation of the two elements, said secondary locking mechanism requiring a suitable unlocking tool.
  • Electric connection device comprising: a first electric connection element (11); a second electric connection element (12) connectable to the first electric connection element (11) by means of respective electric contacts; a removable unlocking tool; a bayonet-type locking and unlocking mechanism (24, 19, 23) configured for coupling and uncoupling the first connection element (11) and the second connection element (12) following a rotation of one with respect to another; a secondary safety locking mechanism (50, 51), configured for preventing a rotation of the first connection element (11) and of the second connection element (12) one with respect to another and a consequent separation of the two elements (11, 12) comprising retractable locking means (84, 85) configured to be unlocked by the removable unlocking tool.
  • Electric connection devices are known which solve this problem by integrating with the electric connection device the unlocking system of the secondary locking mechanism, so that the skilled technician is not required to bring a suitable unlocking tool with him.
  • an electric connection device comprising two connection elements capable of being mutually coupled through a bayonet-type locking mechanism and through a secondary locking mechanism configured for preventing the accidental disconnection of the two connection elements, further comprising a removable unlocking tool, configured both to be connected to the device by a skilled technician, who therefore will not be compelled any more to bring with him any suitable unlocking tool, with the risk of losing it or forgetting it, and to be separated and extracted by the skilled technician, thereby preventing the unlocking of the electric connection device by unauthorized people.
  • the electric connection device of the invention comprises a first electric connection element 10, 10a, for example of the female type, preferably a front capsule 10 of the female type or a flange 10a of the female type for a fastening on a panel, connectable to a second electric connection element 12, 12a, for example of the male type, in particular a front capsule 12 of the male type or a flange 12a of the male type for a fastening on a panel, said first electric connection element 10, 10a and second electric connection element 12, 12a being mutually electrically connectable by means of respective electric contacts; a bayonet-type locking and unlocking mechanism configured for coupling the first connection element 10, 10a and the second connection element 12, 12a following a rotation of one with respect to the other along a first direction and for uncoupling said first connection element 10, 10a and said second connection element 12, 12a following a rotation of one with respect to the other along a second direction, opposite to the first; a secondary safety locking mechanism, configured for preventing the rotation of the first connection element 10, 10a and
  • the retractable locking means 22, 24 preferably comprise a seat 22, in a preferred way obtained on the external surface of the first connection element 10, 10a, a pin 24, in a preferred way inserted in a housing 25 obtained in the second connection element 12, 12a, and an elastic element, for example a spring, contiguous to the pin 24, also inserted in the housing 25; said secondary locking mechanism requires to be unlocked by the insertion of the suitable removable unlocking tool 32 in the seat 22 which determines the retraction of the pin 24 in the housing 25 in order to allow the rotation of said first and second connection elements 10, 10a, 12, 12a one with respect to the other along the second direction which implies its separation.
  • the electric connection device of the invention comprises the removable unlocking tool 32, slidingly connectable to the first connection element 10, 10a, through removable connecting means 40 configured to be removably fastened to the electric connection device.
  • the connecting means comprise a ring nut 40 fastened to the first connection element 10, 10a, so that the removable unlocking tool 32 is sliding along first guiding means 48 made thereon both with respect to the first connection element 10, 10a, and with respect to the connecting means 40; in particular, said connecting means 40 are configured to be removably fastened to the first connection element 10, 10a, through removable fastening means of the known type, for example a screw, to connect the removable unlocking tool 32 to or to be remnoved from the first connection element 10, 10a, remolving the removable fastening means, to separate the unlocking tool 32 from the electric connection device.
  • removable fastening means of the known type, for example a screw
  • the connecting means 40 comprise second guiding means 46 configured to cooperate with the first guiding means 48 of the removable unlocking tool 32, in order to slide said removable unlocking tool 32, once connected to the first connection element 10, 10a, both with respect to the connecting means 40 and with respect to the electric connection device, comprising said removable unlocking tool 32, stop means 47, for example steps 47 obtained next to the ends of the guiding means 46, 48, configured to stop their sliding along the guiding means 46, 48 at the end of their stroke.
  • the bayonet-type locking mechanism is configured so that, when the first connection element 10, 10a and the second connection element 12, 12a are pushed one towards the other to be coupled, at least one projecting element 14, obtained on the internal surface of the first connection element 10, 10a and placed next to at least one "L"-shaped groove 18, obtained on the external surface of the second connection element 12, 12a, vertically slides inside a first section 23 of the groove 18, till it reaches a second section 21 of said groove 18, after that, when the first and the second connection elements 10, 10a, 12, 12a, are rotated along the first direction to be coupled, the projecting element 14, horizontally slides inside said second section 21 of the groove 18; preferably, the connection elements 10, 10a, 12, 12a comprise two projecting elements 14, and two "L"-shaped grooves 18.
  • the removable unlocking tool 32 configured to be inserted in the seat 22 of the first connection element 10, 10a in contact with the pin 24 and pressed against said pin 24 in order to push it inside the housing 25 obtained in the second connection element 12 and unlock the secondary locking mechanism allowing a user to rotate the first and the second connection elements 10, 10a, 12, 12a in order to uncouple them, comprises a projection 45 whose sizes coincide with those of the seat 22 in which the projection 45 is inserted in order to unlock it.
  • the electric connection device allows the skilled technician to choose whether removing the unlocking tool, for preventing the unlocking of the electric connection device by unauthorized people, or keeping the unlocking tool connected to the connection device.
