Abstract

The invention relates to the technical field of passive balancers, particularly to a rotary type step-by-step balancer and a preparation technology thereof. The rotary type step-by-step balancer comprises a bottom printed board, a three-reed connector component, a top rotary printed board, a face gear with a shaft, an end face positioning reed and a shell shaft sleeve and is characterized in that the three-reed connector component and a balancer peripheral circuit are arranged on the bottom printed board; the top rotary printed board is arranged at the top of the bottom printed board; the reeds of the three-reed connector component are in contact with the electrical contact point bonding pad of the electrical resistance attenuation network of the top rotary printed board; the top rotary printed board is provided with the face gear with the shaft; a spindle is arranged at the bottom of the face gear with the shaft; the bottom of the spindle inserts into the circular holes of the top rotary printed board and the bottom printed board. Compared with the prior art, the rotary type step-by-step balancer integrates 16 types of pad values into one balancer, facilitates production and field debugging of equipment, has a novel structure and complete functions, is reasonable in mechanical structural design and convenient to process, and can be produced in large batches.

Description

[technical field] [0001] The invention relates to the technical field of passive equalizers, in particular to a rotary stepping equalizer and its preparation process and application. [Background technique] [0002] Passive equalizers commonly used in CATV systems can generally be divided into two types: [0003] 1. fixed equalizer; [0004] 2. Variable equalizer. [0005] The fixed equalizer has the advantages of clear and intuitive equalization value and stable value, but an equalizer can only have one definite equalization value. If it wants to cover all commonly used equalization values ​​(such as 0-15dB), it must have 16 different values. The equalizer, which caused the equipment on-site debugging sometimes because there are not enough spare parts can not find the required equalization value. [0006] The variable equalizer has the advantage of continuously adjusting the equalization value, but the equalization value cannot be directly displayed, and the required va...
