Abstract:
A connecting device for at least one electric conductor comprising:an insulating casing or body defining at least one connecting housing, the at least one connecting housing including: an interconnection piece arranged in the casing and provided with at least one connecting branch, a looped connecting spring comprising in succession: a bearing branch arranged on the connecting branch of the interconnection piece, an elbow connecting the bearing branch to an operating back piece and a connection branch extending the operating back piece on the opposite side to the elbow towards the bearing branch and exhibiting a connection opening intended to accommodate the electric conductor to press it against the interconnection piece, means for compressing the connecting spring to uncover the connection opening and allow the electric conductor that is to be connected to be introduced, the means for compressing a cam which is fitted into the at least one connecting housing so as to be able to move in terms of rotation between a start of travel position corresponding to the connecting spring being in a relaxed state and an end of travel position corresponding to the connecting spring being in a compressed state, and the cam is provided with an operating lever extending at least partially out of the casing to allow the cam to be operated between the start and the end of travel positions and which has a cam path comprising, on the one hand, a zone known as the dead zone, through which the cam can pivot from the start of travel position without acting on the connecting spring and, on the other hand, a zone known as the active zone, following on from the dead zone, in which the cam gradually compresses the connecting spring as it rotates towards the end of travel position, which the device comprises means of slowing the rotation of the cam in the start-of-travel position and end-of-travel position, the means of slowing the rotation of the cam includes a rib and stalks.
