Description

Technical Field

[0001] This invention relates to the field of switching power supply technology, specifically to a power connection structure for a switching power supply. Background Technology

[0002] A switching power supply, also known as a switching converter or switching power supply, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage at a certain level into the voltage or current required by the user through different architectures.

[0003] Existing patent document CN206211072U discloses an electrical connection structure. This conductive connection includes a conductive base that can be fixedly attached to an insulating base. The end of a conductive spring is inserted into an annular sleeve, and a spring piece deforms and abuts against the end of the conductive spring. The end face of the conical sleeve has a recessed slit that penetrates both the inside and outside of the conical sleeve. The aforementioned spring piece is formed between every two slits. Initially, the minor diameter of the conical sleeve is smaller than the outer diameter of the conductive spring end, and the major diameter is not smaller than the outer diameter of the conductive spring end. The lower port periphery of the annular sleeve extends inward to form a ring. The periphery of the major diameter port of the conical sleeve and the inner periphery of the ring are fixed together. The structure also includes an electrical connection terminal. The end of the conductive spring is inserted into the insertion structure of the conductive connection portion of the electrical connection terminal, and the conductive spring and the circuit board are electrically connected through the terminal. Fixed relative to the circuit board, during assembly, workers only need to insert the conductive spring into the terminal to achieve the spring's fixing and conductive functions, eliminating the need for welding, simplifying the manufacturing process, and improving production efficiency. It also includes an insulating base, which is fixed to the circuit board. At least one section of the conductive connection part is fixed inside the insulating base, facilitating the fixing of the insulating base and the circuit board, simplifying processing, and avoiding damage to the conductive connection part. The insertion structure includes a ring sleeve and a spring piece. The end of the conductive spring is inserted into the ring sleeve, and the spring piece elastically abuts against the end of the conductive spring, ensuring contact between the spring end and the spring piece, ensuring electrical connection between the spring and the conductive connection part, and facilitating spring positioning. The end face of the tapered sleeve has a recessed slit that penetrates the inside and outside of the tapered sleeve. Through the slit, the aforementioned spring piece is formed between every two slits, enhancing the spring piece's elasticity and better achieving fixing and conductivity with the spring.
