Filter

Abstract

The invention relates to a filter which comprises a box body, wiring devices, clamping devices and a bottom cover plate. The three wiring devices are arranged on the left side of the box body, the two wiring devices are arranged on the right side of the box body, the clamping devices are symmetrically installed on the front side and the rear side of the box body, and the bottom cover plate is clamped below the box body through the clamping devices. According to the invention, the problems that when the connecting line on the filter is installed, the connecting line is easy to loosen in the later period in the traditional installation method, the connecting strength is reduced due to the influence of careless touch during working, the connecting line connector falls off from the filter, the working of the filter is blocked, and after the resistor and the like in the filter are installed, the bottom cover plate and the box body are generally connected through a clamping method, after clamping, if internal parts need to be replaced, the bottom cover plate and the box body need to be separated, the clamping position may be damaged, and installation between the bottom cover plate and the box body is affected.

Description

technical field [0001] The invention relates to the technical field of filter production, in particular to a filter. Background technique [0002] A filter is a frequency selection device consisting of capacitors, resistors and casings. The filter can effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency or eliminate a power signal of a specific frequency. [0003] The existing filters usually have the following defects during installation: 1. After the existing filters are assembled, the connecting wires need to be installed, while the traditional installation method usually uses nuts to connect the connecting wire joints, However, this method is prone to loosening in the later stage, and when working, careless touch will affect and reduce the connection strength, causing the connector of the connecting wire to fall from the filter and blocking the wor...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the need to install the connecting wires after the existing filter is assembled, while the traditional installation method usually uses nuts to connect the joints of the connecting wires, and this method is prone to loosening in the later stage, and the When the filter is connected, careless touch will affect and reduce the connection strength, causing the connector of the connecting line to fall from the filter, blocking the work of the filter, and after the installation of the capacitors and resistors in the filter is completed, usually through the clamping Method: Connect the bottom cover with the box body. After the card connection, if you need to replace the internal parts, you need to separate the bottom cover from the box body, which may cause damage to the clip joint and affect the bottom cover and box body. Installation and other problems between
