With the development of electronic devices towards miniaturization and high power density, the heat generated by inductors during operation increases significantly, leading to increasingly prominent temperature rise problems. Traditional inductor bases are mostly made of metal or plastic materials, which have limited heat conduction performance and single internal heat dissipation structure, such as relying only on the surface of the base or simple straight hole heat dissipation, which is difficult to meet the high heat dissipation demand and long-term high-temperature operation may cause inductor performance degradation or even failure.

[0003] In addition, conventional pins are mostly straight insertion or simple bending design, and when the circuit board is subjected to mechanical vibration or thermal stress, the pins are prone to bending and deformation, leading to poor contact. At the same time, the installation method of traditional inductor bases relies on welding or screw fixing, which has problems such as complex process, low efficiency, and inconvenience to disassemble. Although some buckle type design schemes simplify the installation process, they lack a rotation prevention mechanism, and the inductor may be displaced due to external force during use, damaging the connection reliability with the circuit board.

[0027] Referring to the drawings Figure 1 - the drawings Figure 4 shown; the inductor base, wherein the ceramic seat 21 made of high thermal conductivity ceramic material is contained, the shape is a cuboid or a cylinder, the top is flat for fixing the inductor, 4-5 parallel channels are evenly opened in the horizontal direction inside the ceramic seat, penetrating through the left and right sides of the ceramic seat, forming the horizontal airflow path; 4-5 parallel channels are evenly opened in the vertical direction inside the ceramic seat, perpendicular to the horizontal channels, forming a three-dimensional mesh heat dissipation structure. The horizontal and vertical channels are arranged in two layers, each layer contains 4-5 channels, and the two layers are connected through the vertical through hole, enhancing the heat dissipation efficiency.

[0028] Two Z-shaped pins 25 are symmetrically distributed left and right with the ceramic base axis as the reference, made of copper alloy, and the surface is tinned to improve conductivity. The pin is a Z-shaped pin with a 90-degree turn, including two horizontal sections and a vertical bending section in the middle. A triangular support plate is welded at the right angle bending of the Z-shaped pin, and the support plate and the pin form a 45-degree inclination angle to form an isosceles triangle reinforcing structure. The support plate is made of stainless steel and is fixed by laser welding to enhance the bending resistance of the pin.

[0029] In the buckle assembly 26, the top plate 261 is a circular metal sheet fixed to the center of the bottom of the ceramic base, and the clamping block 262 is four arc-shaped elastic metal sheets arranged in a ring array at the bottom of the top plate, each clamping block is spaced 90 degrees apart, allowing the clamping block to contract inwardly or expand outwardly when pressed. The clamping seat 263 is a ring-shaped plastic part embedded in the circuit board mounting hole, and four independent clamping grooves 264 are formed in the inner cavity side wall, the groove width is slightly larger than the thickness of the clamping block 263, and the clamping grooves are separated by partitions to prevent the clamping block from rotating. In use, the clamping block 262 is aligned with the clamping groove 264 and pressed down, the clamping block is squeezed into the cavity, and after being reset, it is clamped into the clamping groove to achieve quick locking of the ceramic base and the circuit board.
