Technical Field

[0002] An inductor is a device or sensor used to measure inductance. Inductance is an important component in an electrical circuit. It refers to the electromagnetic induction phenomenon generated in a conductor, usually consisting of a coil or coil. Inductors are used to measure the size of this inductance for use in circuit design and troubleshooting. The connection base of an inductor is a device used to mount and connect an inductor. It is usually a base or base with a connection interface and pins that match the inductor so that the inductor can be fixed on a circuit board or other device and connected to the circuit. The design of the connection base is usually closely related to the type and size of the inductor to ensure correct installation and connection.

[0003] However, the existing connection base still has some shortcomings and areas for improvement in actual use. The size of the existing base structure is mostly fixed, and it is generally used in combination with a specific inductor, and the size cannot be adjusted. At the same time, the existing base structure is inconvenient when connected to the coil connector of the inductor. Manual support is required during welding, and if you are not careful, the pin welding may be skewed, thereby affecting normal use. After installation, because it is an electronic component, it will generate a certain amount of heat when working, and the existing structure cannot provide good ventilation and heat dissipation for it. Therefore, technicians in this field provide a base structure with adjustable size to solve the problems raised in the above background technology. Utility Model Content
