Embodiment Construction

[0017] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, a preferred embodiment of the present invention is combined with the accompanying drawings below to describe in detail as follows:

[0018] Such as figure 2 The schematic diagram of partial circuit interception of the improved relay unit of the power supply device of the present invention is shown. The present invention discloses an improvement of the relay unit of the power supply device of the electrostatic clutch, and its innovative features are derived from the figure 2 It can be clearly shown that: in the welding position of the original relay K1 (such as figure 1 ) adopts the way of IC base plugging, and replaces the original relay K1 with a single PCB board with modular design and relay function. The relay K3, and the input and output pins of the relay K3 correspond to the input and output pins of the original relay K1 at the IC ...

Abstract

The invention discloses a relay unit improvement of an electrostatic pull-in device power supply, which is characterized by adopting IC base inserting mode at the welding position of the original relay (K1); substituting the original relay (K1) to a modular designed single PCB plate with relay function, wherein, the PCB plate is welded with row-shaped needle seats, RC filter circuit and a relay (K3) with strong current capacity, the input and output pins of the original relay (K1) and the input and output pins of the relay (K3) are mapped to the probes on the row-shaped needle seats for corresponding welding. Adoption of the inventive relay unit improvement method can effectively eliminate the arc discharge phenomenon and filter the vast majority of high-frequency signals to resolve the return coupling voltage problem of the machine after the ESC, and to extend the life of the relay; and increase the rotating restoration velocity of the machine; simultaneously reduce the integral condemnation factor of the ESC supply unit.

Description

technical field [0001] The invention relates to an electronic control device, in particular to an improvement of a relay unit of an electrostatic clutch power supply device. Background technique [0002] A relay is a basic electrical device that is used to open or close a number of independent circuits. This operation is achieved using an electromagnetic field generated by a voltage-controlled coil winding. When the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value, the electronic automatic control device whose output will change in a jump. It has a control system (also known as input circuit) and a controlled system (also known as output circuit), usually used in automatic control circuits, it is actually an "automatic switch" that uses a smaller current to control a larger current . Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] When the general relay is used in ...
