Description

Technical Field

[0001] This utility model relates to the field of inductor technology, and in particular to a surface-mount bottom electrode type integrally molded inductor. Background Technology

[0002] Molded inductors are a type of high-end inductor. Their manufacturing process involves directly molding the magnetic core material onto the coil. These inductors are characterized by their robust structure, precise characteristics, and magnetic shielding, effectively resisting electromagnetic interference (EMI). They exhibit very low audible noise, allowing for high-density placement. Despite their small size, they can handle large currents and maintain good temperature rise and inductance characteristics even in complex environments. Therefore, they are ideally suited for DC-DC power management modules (PMUs) in slim and lightweight smart mobile terminal products, and are applicable to various fields such as mobile phones, automobiles, aviation, communications, electric vehicles, and charging stations. After production and packaging, the inductor's pins need to be protected to prevent damage before use. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a patch bottom electrode type integral molded inductor, including an inductor body, a fixing groove is provided at the bottom of the inductor body, a pin is provided on the inner side of the fixing groove, a protective mechanism is provided in the fixing groove, the protective mechanism includes a protective cover and a storage slot, the protective cover is slidably inserted into the inner side of the fixing groove, and a storage slot is provided on the top of the protective cover.

[0005] Preferably, there are two of each of the fixing slots and pins.

[0006] Preferably, the fixing groove is a trapezoidal structure, the protective cover is a trapezoidal structure, and the outer wall of the protective cover is in contact with the inner wall of the fixing groove.

[0007] Preferably, an anti-detachment mechanism is provided at the connection between the fixing groove and the protective cover. The anti-detachment mechanism includes a pin hole, a raised bead, and a post. A pin hole is provided at one end of the inner cavity of the fixing groove, and a raised bead is integrally formed on the outer side of one end of the protective cover.

[0008] Preferably, the pin hole is made of rubber, the protruding bead is made of rubber, and the inner wall of the pin hole is smaller than the outer wall of the insertion post.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When the patch bottom electrode type integrated molded inductor is not in use or is stored in packaging, the protective cover can be inserted into the fixing slot, so that the pins are in the storage slot. In this way, the pins can be protected by the protective cover. The fixing slot is set with a trapezoidal structure, and the protective cover is set with a trapezoidal structure, which can fix the protective cover and prevent it from falling off, thus providing better protection for the pins. When the protective cover is inserted into the fixing slot, the pin hole will be inserted into the post, and the post will be squeezed and deformed to insert into the pin hole. This can ensure the connection between the post and the pin hole is stable. During insertion, the protruding bead will also deform and be placed at the connection between the protective cover and the fixing slot, increasing the friction and thus better preventing it from falling off. The handle makes it easier to remove the protective cover. Attached Figure Description
