[0001] The utility model relates to the technical field of choke brackets, in particular to a limiting bracket for a choke. Background Art

[0002] A choke is an electronic component used to control electric current. It is usually composed of a coil wound on a magnetic material. When current passes through the choke, it generates a magnetic field, which interacts with the magnetic field generated by the current, thereby limiting the flow of current. Chokes are often used in the filter circuit of DC power supplies. They can filter out high-frequency noise in the power supply and make the current more stable. In addition, chokes can also be used in transformers and inductors to regulate voltage and store energy.

[0003] In the actual production of chokes, the coil needs to be wound around the magnetic ring. Some existing magnetic rings are provided with brackets inside, which makes the winding very inconvenient, resulting in low production efficiency. In addition, when the wound magnetic ring is installed on the bracket, the pins on the coil need to be inserted through the bottom of the bracket to facilitate the subsequent wiring. This step is also troublesome in actual installation, which will reduce the use effect of the device. Therefore, it is urgent to solve the above problems. Utility Model Content
