Embodiment 1

[0025] Such as Figure 1 to Figure 5 As shown, the present invention proposes a filter with multiple filtering functions, including: a main power supply filter module, a motor power supply filter module, a motor output PWM power supply filter module, a bus signal filter module, a serial port signal filter module and a chassis. The main power filter module for filtering the main power supply, the motor power supply filter module for filtering the motor power supply, the motor output PWM power filter module for filtering the motor output PWM power, and the A bus signal filtering module for filtering the bus signal and a serial port signal filtering module for filtering the serial port signal.

[0026] In order to avoid mutual coupling caused by different signals generated by each module in the chassis, the chassis includes: a panel 11, a first installation groove body 12, a second installation groove body 13, a third installation groove body 14, a fourth installation groove body...

Embodiment 2

[0037] Such as Figure 6 as well as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that in Embodiment 1, when the ground plate 2 is connected with the feed-through capacitor, the mounting plate 31 is not easy to connect with the ground plate 2, and the feed-through capacitor is easily damaged during connection, so In this embodiment, on the basis of embodiment 1, only the first connecting component 3 is improved.

[0038] In order to avoid damage to the grounding plate 2, a first connection assembly 3 is installed at both ends of the grounding plate 2;

[0039]Each first connection assembly 3 includes: a mounting bracket 31', a first screw rod 32', a moving plate 33', a first spring 34', two vertical rods 35', two first wedges 36', two second Wedge 37', two guide cylinders 38', two guide rods 39' and two second springs 30', mounting frame 31' stand on the fourth mounting groove body 15 inner wall, mounting frame 31' is n-shaped, mounting frame...

Embodiment 3

[0042] Such as Figure 8 to Figure 11 As shown, the difference between this embodiment and Embodiment 1 is only: since the installation of the first installation ring 51 in Embodiment 1 also requires the installation of the connection plate 50, the connection between the connection plate 50 and the first cover plate 16 requires multiple screws, while Installing the first mounting ring 51 also requires multiple screws, and the screws need to be rotated multiple times to press the first mounting ring 51 on the first cover plate 16, resulting in difficult operation. In order to avoid the above problems, the present embodiment On the basis of 1, only the second connection assembly 5 is improved.

[0043] In order to realize the installation of the first cover plate 16 and the connecting head 4 only by rotating the rotating rod 542 less than one turn, the connecting head 4 is located on the side of the first cover plate 16 away from the first installation groove body 12, the connec...

Abstract

The invention provides a filter with multiple filtering functions, includes a main power filter module, Motor Power Supply Filter Module, Motor Output PWM Power Filter Module, Bus Signal Filtering Module, A serial port signal filtering module and a chassis, A main power filter module for filtering the main power supply is installed in the chassis, A motor power supply filter module for filtering amotor power supply, a motor output PWM power supply filter module for filtering a motor output PWM power supply, a bus signal filter module for filtering a bus signal, and a serial signal filter module for filtering a serial signal. The motor power supply filter module includes a motor power supply filter module for filtering a motor output PWM power supply, a bus signal filter module for filtering a bus signal, and a serial signal filter module for filtering a serial signal. The filter with the multi-filtering function solves the problems of occupying large volume, disorderly connection anderror-prone connection caused by each filter module being installed independently in the prior art.

Description

technical field [0001] The invention relates to filtering equipment, in particular to a filter with multiple filtering functions. Background technique [0002] In an electrical appliance, the following circuits need to be used at the same time: main power filter module, motor power supply filter module, motor output PWM power filter module, bus signal filter module, serial port signal filter module, main power filter module, motor The power supply filter module, the motor output PWM power filter module, the bus signal filter module, and the serial port signal filter module are all set independently of each other, resulting in the main power filter module, the motor power supply filter module, the motor output PWM power filter module, and the bus signal filter module 1. The serial port signal filter module occupies a large volume, and there are many connections at the same time, which leads to cluttered connections and is prone to errors. Contents of the invention [0003]...
