Abstract

A choke includes a magnetic core including a winding portion, which has a first end and a second end, a first magnetic portion and a second magnetic portion and an insulated wire. A first angle and a second angle are respectively formed by the first magnetic portion and the winding portion and the second magnetic portion and the winding portion. The second angle is disposed opposite to the second angle. The insulated wire is wound on the winding portion for forming coil turns. The coil turns contacted with the winding portion is disposed at a first degree to the coil turns contacted with the first magnetic portion. The coil turns contacted with the winding portion is disposed at a second degree to the coil turns contacted with the second magnetic portion. The degree of the first angle and the degree of the second angle are greater than 90 degrees.

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...
