Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inductance coils, and particularly relates to an inductance coil with a protection function. Background Technique
[0002] A coil is formed by winding a wire around an insulating tube in a coil-by-coil manner. The wires are insulated from each other, and the insulating tube can be hollow or contain an iron core or a magnetic powder core. An inductance coil is a device that works based on the principle of electromagnetic induction. When an electric current flows through a wire, a certain electromagnetic field will be generated around this wire. And this electromagnetic field of the wire itself will have an inductive effect on the wires within the range of this electromagnetic field. The effect on the wire that generates the electromagnetic field itself is called "self-inductance", that is, the changing current generated by the wire itself generates a changing magnetic field, and this magnetic field further affects the current in the wire. The effect on other wires within the range of this electromagnetic field is called "mutual inductance". Generally, the structure of an inductance coil is usually composed of an induction coil and a winding. The protection performance of the inductance coil is not good. During the transportation of the inductance coil, the coil is easily damaged by impact, and the pins on the inductance coil are easily damaged by impact and bending, resulting in damage to the entire coil, and further increasing the use cost of the inductance coil. Therefore, we propose an inductance coil with a protection function. Content of the Utility Model
