摘要

A device for the exchangeable receiving, and also lightning current resistant, voltage is provided with contact surfaces or pit structure for the protection of operationally not grounded parts of the plant, such as web under works or surface line of means, consisting of a screw cap with inner cavity for receiving the voltage fuse, a connection terminal with a contact surface for the voltage fuse, and an insulating body,characterized in that– the connection terminal as a threaded bolt with a bolt head is formed, whereby the bolt head a based on the threaded section has a larger diameter,– the insulating body in the form of sockets, with an inside diameter, suitable for receiving the threaded bolt, whereby, in the installed state of the bolt head on a first side of a circumferential collar of the insulating body is applied,– a base plate with a complementary threaded extension of the screw cap is provided, wherein the base plate comprises a through opening, in order to receive the bushing insulator which extends with its second side of the circumferential collar with an end face portion of the threaded extension comes to rest and an essentially concentric arrangement of the threaded bolt, the insulating body and aperture of the base plate..
