Low-voltage high-current system fastening device, has angle pieces with hole accommodating fastening screw with Belleville spring bearing on insulator with extension surrounding screw

摘要

The low-voltage high-current system fastening device has a body (1) made of insulating material. A conductor has a connecting bracket (12) which is covered with an insulator (4). The connecting bracket has a hole (121) accommodating a fastening screw (3) with a round head (31). A hexagonal blind bore (311) in the screw may accommodate an Allen (RTM) key. A Belleville spring (2) fits in a recess (43) in the end of an extension of the insulator which takes a bearing on the head of the screw. The end of the extension forms a narrow collar (42).
