Electrical circuit opening and closing control device for battery of vehicle, has nut connected to bar by rod such that, in rotating directions of screw, rod presses bar to close circuit and allows bar to open circuit, respectively

摘要

#CMT# #/CMT# The device has a contact bar (6) including contacts (7, 8) cooperating with studs (1, 2), where the studs are inserted on an electrical circuit. A nut (17) cooperates with an endless screw (21) wedged on a shaft of an electric motor (22), where the nut is connected to the bar by a connecting rod such that, in two rotating directions of the screw, the rod presses the bar to close the circuit and allows the bar to be separated from the studs to open the circuit, respectively. #CMT#USE : #/CMT# Used for controlling the opening and closing of an electrical circuit utilized in a battery of a vehicle for selectively supplying electrical and electronic components of the vehicle. #CMT#ADVANTAGE : #/CMT# The device is simple, reliable, and ensures the direct opening and closing of the contacts to avoid the formation of arcs between the contacts, thus avoiding all accident risks while considering a high voltage of the battery. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an electrical circuit opening and closing control device. 1, 2 : Studs 6 : Contact bar 7, 8 : Contacts 17 : Nut 21 : Endless screw 22 : Electric motor.
