Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chip power inductors, and particularly relates to a chip power inductor with a hollow middle part. Background Art
[0002] In electronic devices such as motherboards, chip inductors, as important electronic components, play an indispensable role. In modern motherboard designs, with the continuous improvement of data transmission speeds, inductors play a key role in the transmission and filtering of high-frequency signals. At the same time, chip inductors also play an important role in memory systems. For example, in the interface circuits of memory chips and hard disk drives, the presence of inductor components helps reduce signal distortion and improve the reliability of data transmission. Chip inductors also play an important role in the heat dissipation system of motherboards, meeting the heat dissipation protection requirements of motherboards.
[0003] This application discloses a chip inductor (CN214505184U). The chip inductor includes: a magnetic base, a magnetic cover, a magnetic core, a plurality of pads disposed on the bottom surface of the magnetic base, and a coil. Among them, the magnetic base includes a body and extension parts disposed on both sides of the body, and the body and the extension parts form a first stepped structure; the magnetic cover is joined to the horizontal stepped surface on the extension part and the vertical stepped surface on the body in the first stepped structure, and a receiving space is defined between the magnetic cover and the magnetic base; the magnetic core is disposed on the body and within the receiving space; the coil is wound around the outer surface of the magnetic core, and both ends of the coil are welded to the plurality of pads. Therefore, through the full contact between the magnetic cover and the magnetic base, the shielding effect and electrical characteristics of the chip inductor are enhanced. However, in use, since the chip inductor is part of the heat conduction system on the circuit board, its own heat conduction is extremely crucial. If heat cannot be conducted and transferred quickly, it may cause damage to the heat-generating components on the circuit board.
[0004] Therefore, we propose a chip power inductor with a hollow middle part. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a chip power inductor with a hollow middle part to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A chip power inductor with a hollow middle part includes a base, a bracket, and an inductor. A sealing cover for sealing protection is embedded at the upper end of the base, and an installation cover for connection protection is fixed at the front end of the base. A plurality of brackets are connected to the outer wall of the base in an interference fit manner, and a chuck with a clamp structure is provided at the end of the bracket. An opening groove for convenient installation and connection is formed between the two chucks on both sides. A ceramic column is sleeved in the middle of the base, and an inductor is embedded between the base and the ceramic column.
[0007] Preferably, the middle part of the base is hollowly distributed, and the hollowly distributed base plays a role in heat dissipation protection.
[0008] Preferably, a heat dissipation plate for heat dissipation protection is laid on the inner bottom of the base, and the heat dissipation plate is connected to the base by glue.
[0009] Preferably, the pin part of the inductor is connected to the connection terminal, and the inductor is installed at a preset position on the target circuit board through the connection terminal.
[0010] Preferably, partitions are distributed between the connection terminals.
[0011] Preferably, the connection terminals are fixed at the front end of the mounting cover, and the mounting cover is integrally injection-molded with partitions along the middle of the two connection terminals.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the chip power inductor with a hollow middle is in use, the chuck and the opening groove, as the clamping components at both ends of the base, can well lift the base off the ground, facilitating the installation of the base on the target circuit board. At the same time, the opening groove has a clamping and installation function, ensuring that the base is firmly fixed on the target circuit board.
[0013] The base and the heat dissipation plate, as the bearing and heat dissipation components of the inductor, are designed with a sealed structure as a whole. There is no obvious gap at the connection between the mounting cover and the base, ensuring that the chip power inductor can be used for a long time.
[0014] The connection terminal, as the component for connecting the inductor to the preset position of the target circuit board, is isolated by partitions in the middle, enabling the connection terminal to be well connected to the target circuit board and reducing the possibility of short circuits caused by circuit crossovers.
