Electro-Mechanical Programmer and Electrical Connector Comprising One Such Programmer

Electromechanical programmer comprising:

• a manually adjustable programming dial,
• a synchronous drive motor for rotation of the dial which is equipped with an output pinion, and
• mechanical transmission means for transmitting of the movement of the output pinion to the dial, wherein the transmission means are adapted to allow the adjustment of the angular position of the dial by a rotary displacement of the dial in a first direction which is identical to the direction in which the dial is driven by the motor, and wherein the transmission means comprise first and second friction gear assemblies adapted to enable the adjustment of the angular position of the dial by a rotary displacement of the dial in a second direction which is contrary to the direction in which the dial is driven by the motor, the first assembly being provided between the output pinion of the motor and the second assembly, and the second assembly being provided between the first assembly and the dial, such that the movement of the output pinion is transmitted to the dial successively via the first and second assemblies, and that during the adjustment of the dial the first assembly is adapted to decouple the output pinion and the second assembly when the dial is displaced in the first direction and the second assembly is adapted to decouple the dial and the first assembly when the dial is displaced in the second direction.
