Description

Technical Field

[0001] This application relates to the technical field of DC power transmission, and particularly to a rectifying device and a magnetic therapy power supply. Background Art

[0002] Magnetic therapy power supplies usually need to convert alternating current into stable direct current to drive electromagnetic coils or other electronic components in magnetic therapy devices. Currently, the rectifying components of magnetic therapy power supplies are composed of thyristors and diodes. The diodes play a role of unidirectional conduction in the rectifying circuit, allowing the positive or negative half cycle of the alternating current to pass through the circuit and be converted into unidirectional direct current. The combination of thyristors and diodes can achieve more complex rectifying functions, such as full-wave rectification or bridge rectification, thereby improving the efficiency and output quality of the power supply.

[0003] The current rectifying components include thyristors, diodes, two copper bars, and two crimping seats. The thyristors and diodes are arranged side by side. The two crimping seats press the two copper bars against the opposite ends of the thyristors and diodes. The contacts at both ends of the thyristors are electrically connected to the contacts at both ends of the diodes through the two copper bars respectively. Since the thyristors and diodes are arranged side by side with a gap, along the arrangement direction of the thyristors and diodes, the crimping seats require a relatively large length dimension. When the two crimping seats are locked and connected by fasteners, they are prone to deformation, inclination, or even fracture. Moreover, since each copper bar needs to be in contact with the contacts on the same side of the thyristors and diodes simultaneously, in order to provide sufficient contact area, each copper bar needs to have a relatively large volume, resulting in an increase in cost.
