Abstract

The invention relates to a choke, which includes a magnetic core and an insulated wire. The magnetic core includes a winding part, a first magnetic part and a second magnetic part. The winding part has a first end and a second end. The first magnetic part and the winding part form a first included angle. The second magnetic part It forms a second included angle with the winding portion structure and jointly defines the winding space. The second included angle is arranged opposite to the first included angle in the winding space. The insulated wire is wound around the first magnetic part or the second magnetic part, and is wound around the winding part from the first included angle or the second included angle in the winding space to form a coil turn. The coil turns in contact with the winding part and the coil turns in contact with the first magnetic part are arranged at a first angle, and the coil turns in contact with the winding part and the coil turns in contact with the second magnetic part are arranged at a second angle .

Description

technical field [0001] The invention relates to a choke, in particular to an ultra-small rubber-sealed choke which improves the short circuit between coil layers and the distribution of inductance. Background technique [0002] In various electronic devices, the function of the inductor (Inductor) and the choke (Choke) is to stabilize the current in the circuit and filter out noise. The function is similar to that of the capacitor (Capacitor), which is also used to store and release the current in the circuit. The electric energy is used to adjust the stability of the current, the only difference is that the capacitor stores electric energy in the form of an electric field, while the inductor and choke store it in the form of a magnetic field. [0003] see figure 1 , which shows a schematic cross-section of an existing choke. Such as figure 1 As shown, the existing choke 1 includes a magnetic core 10, a wire 11, a magnetic glue 12, and a pair of electrodes 13, wherein the...
