Abstract

The invention discloses a magnetic power switch box and solves the problem that an existing magnetic switch is not applicable to underground shafts with explosion-proof requirements. The magnetic power switch box comprises a left binding post (12) and a right binding post (13) respectively arranged at the bottom end of a switch box body (6), an up-and-down vertical slide way (8) is arranged on a bottom plate in the switch box body (6), a slide base (9) is movably arranged on the slide way (8), an inner magnet body block (2) is fixedly arranged on the middle part of the slide base (9), a plug (3) is arranged at the upper end of the slide base (9), an insulation pad (11) is arranged on the plug (3), a left power connecting piece (10) and a right power connecting piece (4) are respectively arranged at the left and right ends of the plug (3), a connection circuit socket piece (14) is arranged on the top end of the slide way (8) in the switch box body (6), and an outer magnet body block (7) is correspondingly attracted with the inner magnet body block (2). The magnetic power switch box is particularly applicable to underground shafts and places with dust.

Description

Technical field [0001] The invention relates to a low-voltage switch box, in particular to a sealed low-voltage switch box with explosion-proof function. Background technique [0002] For a low-voltage switch, it is generally operated by pulling, pulling or pressing, etc., to make the contacts in the circuit on and off to achieve the purpose of turning on or off the power supply. These switches are simple and practical, but they are limited when used in underground mines with explosion-proof requirements. There are also some power switches designed using the characteristics of magnetism, such as the "Magnetic Safety Power Switch" with Chinese Patent Application No. 88204746, the "Power Switch" with Chinese Patent Application No. 892057028, and the "Magnetic Switch" with Chinese Patent Application No. 902063686. "Voltage control switch", these types of magnetic switches all use a combination of electromagnetic and permanent magnets, and are not suitable for use in underground m...
