Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic circuits and communication technology, and in particular to a support base for a tapered inductor. Background Technology
[0002] Tapered inductors maintain consistent performance across an extremely wide bandwidth (e.g., 10MHz to 50GHz), making them widely used in millimeter-wave circuits and optical wireless communication systems. Typical applications include DC bias circuits, amplifier design, lithium niobate electro-optic modulators, and analog direct-modulation lasers, effectively supporting the demands of high-frequency signal processing and transmission. In recent years, with the continuous upgrading of consumer electronics and the rapid development of emerging technologies such as 5G communication, the Internet of Things, and artificial intelligence, the market demand for high-performance, high-reliability tapered inductors has increased significantly. Their broad application prospects and stable bandwidth characteristics are making them an indispensable key component in modern high-frequency electronic systems.
[0003] Currently, flying wire tapered inductors mainly face the following problems in practical applications:
[0004] (1) Flying wire type tapered inductors are usually cone-shaped with a diameter that gradually changes along the axial direction. The leads are located at the small end and the large end of the cone, respectively. This asymmetrical lead layout and three-dimensional spatial structure makes it difficult to position during installation and makes it difficult to achieve stable and repeatable assembly. It is particularly unsuitable for use in space-constrained or high-density integrated circuit environments.
[0005] (2) During manual installation, the placement angle of the flying wire tapered inductor cannot be precisely controlled, and additional parasitic capacitance is easily introduced due to posture deviation, causing the inductance value to deviate from the expected value, and the consistency and high-frequency performance to drop significantly, thereby affecting the stability and signal integrity of the overall circuit.
[0006] (3) In typical installation methods, flying wire tapered inductors are suspended and lack effective mechanical support and fixation, resulting in poor vibration and shock resistance. Under mechanical stress or environmental vibration conditions, they are prone to positional displacement or even detachment, which seriously affects the reliability and service life of the equipment. Utility Model Content
[0007] The purpose of this invention is to provide a support base for a tapered inductor, which can ensure that the tapered inductor is fixed at the optimal angle, eliminate the inconsistency of angle during manual installation, and increase the shock resistance and anti-interference capability of the tapered inductor.
[0008] To solve the above technical problems, this utility model provides a support base for a tapered inductor, including a support body. The support body adopts a hexagonal structure and has an upper surface and a lower surface that are arranged opposite to each other. The lower surface is used to fix it to the surface of a circuit board. An inclined platform is provided on the upper surface, and the inclined platform is inclined downward from top to bottom.
[0009] A slot is provided on the inclined platform for fixing a tapered inductor. The side of the slot facing the tapered inductor is a conical arc surface. The large end of the tapered inductor is located at the top of the slot, and the small end is located at the bottom of the slot.
[0010] Compared to existing technologies, this invention, by setting the slot on an inclined platform with a certain tilt angle, ensures that the tapered inductor is fixed at the optimal angle, eliminating angular deviations caused by manual installation and greatly enhancing the consistency of the tapered inductor's electrical performance. Furthermore, the support base keeps the large end of the tapered inductor away from the circuit board surface, reducing turn-to-ground parasitic capacitance and preventing high-frequency self-resonance. Simultaneously, the support base can be mounted flat on the circuit board surface, and its stable support structure greatly enhances the inductor's resistance to disturbances and vibrations, allowing it to withstand stronger mechanical shocks.
[0011] In addition, the inclined platform gradually approaches the lower surface from the upper surface.
[0012] In addition, the tapered inductor is fixed in the slot by adhesive bonding.
[0013] In addition, the support body is integrally formed.
[0014] In addition, the material of the supporting body is any one of alumina ceramic, silicon carbide ceramic, resin, and plastic. Attached Figure Description
