Description

Technical Field

[0001] The utility model relates to the technical field of inductor tooling moulds, in particular to a tooling mould for a wave modulation inductor. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only blocks the change of current. If there is no current flowing through the inductor, it will try to block the current from flowing through it when the circuit is connected; if there is current flowing through the inductor, it will try to maintain the current when the circuit is disconnected. An inductor is also called a choke, a reactor, or a dynamic reactor. Inductors mainly play the role of filtering, oscillating, delaying, trapping, etc. in the circuit, as well as screening signals, filtering noise, stabilizing current, and suppressing electromagnetic interference. The most common role of inductors in circuits is to form an LC filter circuit together with capacitors. Capacitors have the characteristics of "blocking DC and passing AC", while inductors have the function of "passing DC and blocking AC".

[0003] Existing tooling molds for inductors are all fixed frame models, and the mold height cannot be adjusted according to the height of the inductor. It is often necessary to manufacture molds of different heights to adapt to inductors of different heights, which wastes manpower and material resources. Therefore, a tooling mold for wave modulation inductors is proposed to solve the above problem. Utility Model Content
