| 摘要 |
The invention relates to an apparatus for accommodating voltage-limiting devices, including voltage-limiting devices resistant to lightning current, in an exchangeable manner, said voltage-limiting devices having contact surfaces for protecting system parts not grounded during operation, said apparatus comprising a screw cap (2) having an inner cavity (16) for accommodating the voltage-limiting device, a connection terminal (3) having a contact surface for the voltage-limiting device, and an insulating body (11). According to the invention, the connection terminal is designed as a threaded bolt (3) having a bolt head (10), wherein the bolt head has a larger diameter than the threaded section. The insulating body (11) has a bushing shape having an inside diameter suitable for accommodating the threaded bolt (3). In the assembled state, the bolt head (10) lies against a first side of a circumferential collar of the insulating body (11). A base plate (1) or a base body is provided with a threaded extension (13) that is complementary to the screw cap (2), wherein the base plate (1) or the base body has a passage opening in order to accommodate the bushing-shaped insulating body (11), such that a substantially concentric arrangement of the threaded bolt (3), the insulating body (11), and the passage opening of the base plate (1) or of the base body results. |
