الهيكل الأساسي للمحث

1. الهيكل العظمي يشير الهيكل العظمي بشكل عام إلى قوس لف الملف. بعض أكبر ثابت المحاثات or adjustable المحاثات (such as oscillating coils, choke coils, etc.), most of which are enameled wire (or yarn-covered wire) around the skeleton, and then the magnetic core or copper core, iron core, etc. Installed into the inner cavity of the skeleton to increase its inductance. The skeleton is usually made of plastic, bakelite, and ceramics, and can be made into different shapes according to actual needs. Small المحاثات (such as color-coded المحاثات) generally do not use a bobbin, but instead have the enameled wire wound directly around the core. Air-core المحاثات (also known as unwrapped coils or air-core coils, mostly used in high-frequency circuits) do not use magnetic cores, skeletons and shields, etc., but are first wound on the mold and then take off the mold, and the coil is pulled between each coil. Drive a certain distance.

2. Winding Winding refers to a group of coils with specified functions, which is the basic component of المحاثات. There are single-layer and multi-layer windings. There are two types of single-layer windings: dense winding (conductors are wound one turn after another) and intermediate winding (there is a certain distance between each turn of wires during winding); multi-layer windings have layered flat winding, random winding Winding, honeycomb winding, etc.
3. قلب مغناطيسي وقضيب مغناطيسي يتكون القلب المغناطيسي والقضيب المغناطيسي بشكل عام من الفريت النيكل والزنك (سلسلة NX) أو الفريت المنغنيز والزنك (سلسلة MX) ومواد أخرى ، والتي لها شكل "I" وشكل العمود وشكل القبعة ، شكل "E" ، يمكن تشكيل وأشكال أخرى.

4. اللب الحديدي تشتمل المواد الأساسية الحديدية بشكل أساسي على صفائح الفولاذ السليكونية ، بيرمالوي ، إلخ ، وشكلها في الغالب من النوع "E".

5. Shielding cover In order to prevent the magnetic field generated by some المحاثات from affecting the normal operation of other circuits and components, a metal screen cover (such as the oscillation coil of a semiconductor radio, etc.) is added to it. The use of shielded المحاثات will increase the loss of the coil and reduce the Q value.

6. Packaging materials After some المحاثات (such as color code المحاثات, color ring المحاثات, etc.) are wound, the coils and magnetic cores are sealed with packaging materials. The encapsulation material is plastic or epoxy resin.
