Safety power supply interface device

Abstract

The invention discloses a safety power supply interface device, which comprises a shell (91), a power supply jack device (1) arranged on the lower side wall of the shell (91) and a power plug device arranged on the upper side wall of the shell (91), wherein the power supply jack device (1) comprises a power supply cable (3) and a power supply hole (2) for being electrically connected with the power plug device; the power plug device comprises two ejection screw rod assemblies (8) fixedly connected onto the upper side wall of the shell (91); the two ejection screw rod assemblies (8) are symmetrically arranged relative to the longitudinal axis of the shell (91); and each ejection screw rod assembly comprises a thread fixing sleeve (82) fixed on the upper side wall of the shell (91) and an ejection screw rod (81) in thread match with a thread hole (821) in the lower end wall of the thread fixing sleeve (82).

Description

technical field [0001] The invention relates to the field of power supply equipment, in particular to a safe power supply interface device. Background technique [0002] Reliable and convenient electrical connection is required between some electrical equipment and power supply equipment; however, in the electrical connection of some existing power supply equipment, it cannot guarantee the reliability and stability of the electrical connection; or, in realizing a more reliable electrical connection In connected power supply equipment, it cannot be implemented automatically. Moreover, more importantly, it is impossible to guarantee the position locking after the socket and the insertion rod are engaged, and at the same time mechanically ensure the stable engagement of the insertion hole and the insertion rod before engagement and the position locking after engagement. Contents of the invention [0003] The purpose of the present invention is to provide a safe power supply ...
