Description

Technical Field

[0001] The utility model belongs to the technical field of filters, in particular to a laminated power filter housing. Background Art

[0002] A filter is a frequency-selective device that allows specific frequency components in a signal to pass through while greatly attenuating other frequency components. It is often used to filter out interference noise and perform spectrum analysis. It is one of the most common devices in the field of electronic technology. The housing is one of the important structures of the filter, used to install and protect internal circuits such as resistors, inductors, and capacitors.

[0003] The document with the existing publication number CN221829178U discloses a filter housing, comprising a housing, a cover plate, and a locking assembly. The housing comprises an inner cavity with an opening, wherein the inner cavity is used to mount a circuit board; the cover plate is disposed over the opening and is sealed to the housing; the locking assembly is disposed on the bottom wall of the inner cavity and is used to detachably secure the circuit board within the inner cavity;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The filter housing mentioned above is mainly composed of three parts: a shell, a cover plate and a locking assembly. The shell and the cover plate are used to protect the circuit board, and the locking assembly is used to install the circuit board in the inner cavity of the shell. However, during use, the shell is an integrated molding structure. When the internal circuit board is damaged, the cover plate can only be removed to remove the circuit board, which is not convenient for rapid maintenance and replacement of the internal structure of the shell, resulting in poor practicality.

[0006] 2. The filter housing mentioned above has a locking assembly including screws, height columns and nuts, and the circuit board is fixed to the height columns by screws and nuts. However, during use, since the inner cavity of the housing is an integrated space, it lacks an isolation structure, resulting in only one filter circuit board being installed in the housing, which makes it inconvenient to install multiple filter board assemblies at the same time, and the functionality is poor.

[0007] To this end, we provide a stacked power filter housing to solve the above problems. Utility Model Content
