A pneumatic high pressure switch

Abstract

The invention provides a pneumatic high-voltage switch. The switch comprises a bottom plate, input wiring terminals, output wiring terminals, pressing blocks, transverse rods and the like, wherein the bottom plate is a rectangular insulated plate; a rectangular groove is formed in the middle of the bottom plate; the three input wiring terminals and the three output wiring terminals are arranged on two sides of the rectangular groove respectively; one ends, close to the rectangular groove, of the input wiring terminals and the output wiring terminals are processed into 45-degree chamfer angles; wire pressing holes with rectangular sections are formed in one ends, far away from the rectangular groove, of the input wiring terminals and the output wiring terminals; square sliding grooves are vertically formed in the upper parts of the wire pressing holes; pressing blocks are mounted in the square sliding grooves in a sliding manner and used for pressing wire connectors tightly; and the upper ends of the pressing blocks are connected with the transverse rods. According to the switch, V-shaped conductive blocks adopt inclined surfaces as contact surfaces, so that the pressure per unit area is higher and the conductive effect is good; and in combination with force-magnifying effects of levers, electric contact surfaces become more reliable and can bear high voltage and high current.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a pneumatic high-voltage switch. Background technique [0002] High-voltage switch is one of the electrical components that factories often need to use. Most of the conventional high-voltage switches are manually operated, which is dangerous for workers who often use them. Therefore, there is an urgent need for a high-voltage switch that can be directly operated without hands. . Contents of the invention [0003] In view of the above problems, the present invention provides a pneumatic high-voltage switch, which uses a V-shaped conductive block and an inclined surface as the contact surface. The pressure per unit area is higher, the conductive effect is good, and the force amplification effect of the lever is used to make the electrical contact surface more reliable. Can withstand high voltage and high current. [0004] The technical solution used in the present in...
