Connecting arrangement having a terminal screw with a blind hole covering a through-hole and a fixing screw

摘要

A connecting arrangement is disclosed for an electrical switching device for attaching an electrical connection to the electrical switching device, including a terminal, a fixing screw and a terminal screw including an external thread. The terminal includes a connection opening for introducing the electrical connection, a fixing opening through which the fixing screw can be passed for the purpose of securing the terminal to an electrical contact of the electrical switching device, and a terminal bore having an internal thread through which the terminal screw can be screwed in for the purpose of retaining the electrical connection. The terminal screw includes a through-hole and, arranged concentrically with respect to the through-hole, a blind hole which is embodied for receiving a turning tool. The blind hole covers the through-hole and has a greater cross-sectional area than the through-hole. An electrical switching device including at least one such connecting arrangement is disclosed.
