  • An upper section of the connecting element 200 is preferably contiguous to and forms an integral part of an upper casing member 20 of the secondary connector CTB. Furthermore, at a distal end of the connecting element 200, there is provided an electrical connection 200A configured to establish an electrical interconnection with a corresponding electrical connection, designated 100A, of a connecting element 100 housed within the primary connector CTA, as shown in Figures 3, 4C-E, 4G and 5.

  • This is preferably achieved thanks to the primary connector CTA including a movable connecting element 100 that is displaced as a result of movement of the lever mechanism 150/155 to establish an electrical interconnection between the electrical connection 200A of the connecting element 200 and the electrical connection 100A of the movable connecting element 100.

  • a pair of notches 10a is further provided adjacent the locking member 155 to facilitate manual release thereof from the casing member 10.
  • the upper casing member 20 of the secondary connector CTB exhibits a recessed surface in the area of the upper section of the connecting element 200 to accommodate the presence of the lever 150 and locking member 155, in the locking position.
  • the lever 150 including the locking member 155, may especially be made of steel or stainless steel.
  • FRP fibre-reinforced polymer
  • sliding movement of the connecting element 100 within the casing member 10 is responsive to pivotal movement of the lever 150, which is linked mechanically to the movable connecting element 100.
  • Such mechanical link is ensured by a connecting rod 115 that is pivotably supported at one end to the lever 150 and at another end to the movable connecting element 100.
  • Each of the primary and secondary connectors CTA, CTB are preferably provided with mutually cooperable locking elements 100a, 200a.

  • the recessed portion of the casing member 10 is provided with slots 10b shaped and dimensioned to receive the locking tabs 200a, the locking elements 100a being slidable to project inside the slots 10b and retain the locking tabs 200a in the slots 10b upon movement of the lever 150 from the release position to the locking position.
  • the recessed portion of the casing member 10 and the slots 10b include slanted sides, as shown, to guide insertion of the connecting element 200 in the recessed portion upon the connecting element 200 being received within the primary connector CTA.
  • connecting element 200 is simply received within the recessed portion of the casing member 10, there being no particular mechanical interlocking between the primary and second connectors CTA, CTB. In other words, the connecting element 200 is still in a released configuration and may be extracted from the primary connector CTA.
  • the connecting element 100 Upon pivoting the lever 150 towards the casing member 10, as shown in Figure 4E, the connecting element 100 is urged to slide towards the connecting element 200, along with the locking elements 100a, which causes establishment of a partial mechanical interlocking between the locking elements 100a, 200a, as shown in Figure 4F, and thus between the primary and secondary connectors CTA, CTB.
