Description

Technical Field

[0001] The utility model relates to a clamping type medium and large inductor structure. Background Art

[0002] Inductance is a property of a closed loop and a physical quantity. When current passes through a coil, a magnetic field is induced in the coil, and the induced magnetic field generates an induced current to resist the current passing through the coil. It is a circuit parameter that describes the induced electromotive force effect caused in the coil or in another coil due to the change of coil current. Inductance is a general term for self-inductance and mutual inductance. The device that provides inductance is called an inductor.

[0003] When installing an inductor, welding is usually used to install the inductor on a circuit board. This method is suitable for the installation of small inductors, but not for medium and large inductors. This is because the magnetic core of the inductor is a ring structure, and the contact surface between its outer arc surface and the circuit board is small. After welding, the medium and large inductors will shake due to their large volume, resulting in fracture of the weld. Therefore, a mounting structure is needed to ensure the stability of the installation of medium and large inductors. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and provide a clip-on medium and large inductor structure.

[0005] A clip-on medium-to-large inductor structure comprises an inductor and at least two supporting legs. The inductor comprises a magnetic core and a winding of an annular hollow structure. The supporting legs are fixed on the outer arc surface of the magnetic core. The supporting legs are a rectangular parallelepiped structure as a whole. A clip groove is provided on the surface of the supporting legs. The clip groove runs through the upper end surface and the front end surface of the supporting legs. A corresponding clip block is provided on the circuit board. A U-shaped through hole is provided on the inner bottom surface of the slide groove. A positioning block is provided on the outer side of at least one of the supporting legs. A corresponding positioning groove is provided on the circuit board.

[0006] Preferably, a connecting pin is provided on the lower end surface of the supporting pin, one end of the connecting pin is connected to the lower end surface of the supporting pin, and the other end of the supporting pin is connected to the outer curved surface of the magnetic core.

[0007] Preferably, the number of connecting pins provided on each supporting leg is two.

[0008] Preferably, the connecting pin is connected to the outer arc surface of the magnetic core by welding.

[0009] Preferably, a tapered block is provided on the outer side surface of the supporting foot.

[0010] Beneficial effects: Compared with the prior art, the utility model provides support feet for the installation structure of medium and large inductors, replacing the original welding connection. The clamping structure of the support feet is used to facilitate the positioning of the inductor. The positioning blocks and U-shaped holes on the support feet stabilize the clamping structure to prevent shaking. The conical quick guide function facilitates assembly. It is more convenient to connect the support feet and the magnetic core through the connecting feet, and the structure is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
