Electronic torque wrench with removable battery and system with such a wrench
Abstract:
An electronic torque wrench (10) comprises a hand grip body (11) equipped with a user interface (12), electronics (13) for controlling the wrench, a grasping area (18) and power supply batteries. The hand grip body projects out at the front with a mechanical connecting element (14) which ends at one extreme with a clamping head (16), whereas at the rear end it is equipped with a removable battery element (19) which is connected to the hand grip body through a connector group (20) for electric and mechanical connection. When the battery element (19) is removed, a connector (20a) is uncovered at the rear end of the hand grip body (11) for the connection of the wrench to a matching connector (20c) of an electric cable (21) for connecting to an external unit (22) for supplying power to the wrench and controlling it.
