Controller

Abstract

The invention discloses a controller, which comprises a base, a switch device, a frame body device and a magnetic flux device, wherein the switch device is arranged on the base; the frame body deviceis arranged on the base; the magnetic flux device is matched with the frame body device and comprises a casing, a magnetic flux body, a shaft body component, a magnetic element and a sealing cover; the magnetic flux body is arranged in the casing; the magnetic element is used for sucking the shaft body component; the sealing cover is connected with the casing; the shaft body component comprises ashaft body, an elastic element and a top cover; the shaft body is arranged on the magnetic flux body in a penetrating way; the elastic element sleeves the shaft body; the top cover is used for pushingthe shaft body to move downwards; a buffer element is arranged between the top cover and the shaft body. The magnetic flux device is put on the base by the invention; the service life of the whole controller can be prolonged; the stability of the controller in the use process can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of controllers, and in particular relates to a controller. Background technique [0002] The controller (English name: controller) refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor in a predetermined order. Composed of program counters, instruction registers, instruction decoders, timing generators, and operation controllers, it is the "decision-making body" that issues commands, that is, to coordinate and direct the operation of the entire computer system. [0003] As an important component of the intelligent controller, the magnetic flux directly affects the normal use of the controller by its stability and service life. The existing magnetic flux consists of a shell, a magnetic flux with a coil, a metal shaft, a magnet and a spring, ...

[0003] As an important component of the intelligent controller, the magnetic flux directly affects the normal use of the controller by its stability and service life. The existing magnetic flux consists of a shell, a magnetic flux with a coil, a metal shaft, a magnet and a spring, and its metal When the shaft moves downward, the lower end of the metal shaft will be sucked down by the magnet, because the magnet attracts the metal shaft suddenly, and the metal shaft hits the magnet violently, and the impact force caused by this process will continue to impact, causing the shell to The bottom of the body is due to the impact force and the bottom of the shell falls off, resulting in low stability of the magnetic flux during use and a short service life.
