Abstract

The invention discloses a manual maintenance switch which comprises a switch housing which is made of an insulating material; a shielding layer which is fixed in the switch housing and contacts with the housing or the grounding end of electrical equipment; a plug module which is arranged in the shielding layer; and a socket module which is arranged in the shielding layer and matches the plug module. The manual maintenance switch is advantageous in that through a method of adding a metal thin-wall layer in the inner wall of the manual maintenance switch housing, a terminal part on which currentflows over is surrounded by a metal layer, thereby realizing a purpose of maximal-range shielding to an electromagnetic field; the mounting flange surface of the manual maintenance switch is providedwith a metal elastic sheet which is communicated with the shielding layer; when the manual maintenance switch is mounted on a box body, the metal elastic sheet on the tail end of the shielding layeris closely connected with the housing of the box body; after a high-voltage line is connected, large current flows over the switch in operation and the electromagnetic field is generated; and hereon,the metal shielding layer shields the electromagnetic field, thereby reducing influence to a control system and ensuring stable operation of the electronic equipment.

Description

technical field [0001] The present invention relates to the field of power switches, more specifically, to a manual maintenance switch. Background technique [0002] With the advancement of rechargeable battery technology and charging technology, electric vehicles have become more mature, and many solutions have been transferred to pure electric vehicles, and pure electric vehicles are also getting bigger and bigger. An ensuing problem is that the high energy consumption of the pure electric vehicle solution needs to be combined with fast battery charging technology to have practical significance, especially for large-scale land transportation such as pure electric buses and pure electric cars. For large households, the DC current charging requirements defined by the fast charging standard exceed 400A, which puts a lot of pressure on the electrical components on the charging circuit. [0003] Nowadays, no matter in the electric vehicle battery system or in various electrica...
