Description

Technical Field

[0001] This utility model belongs to the field of power adapter technology, specifically relating to a power adapter with solderless input and output terminals. Background Technology

[0002] Existing power adapters typically have their internal casing soldered to a circuit board via connecting wires to establish electrical connections between the circuit board and the input and output terminals. This type of power adapter has two main problems: first, the soldering process is prone to issues like incomplete soldering or weak connections, resulting in poor product quality; second, the entire power adapter manufacturing process requires soldering, leading to low production efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a power adapter with solderless input and output terminals. Its internal input and output terminals are designed to be snap-fit ​​connected to the elastic conductive sheet of the circuit board, replacing the existing soldering structure, ensuring the reliability of electrical connection, improving product quality, and eliminating the need for soldering operations during manufacturing, thus improving production efficiency.

[0004] This utility model is achieved through the following technical solution:

[0005] A solderless power adapter for input and output terminals includes a lower cover, an upper cover, and a circuit board. The lower cover has two AC input plugs extending into its interior, and slots for inserting DC output lines. The lower cover's interior contains protrusions, connector mounting bases, and circuit board slots. Two conductive input plates each include an input connector at one end and an input snap-fit ​​hole at the other end. Each input connector includes mutually pressing arc-shaped spring clips. Each input connector is inserted into the connector mounting base, and the two input snap-fit ​​holes engage with the AC input plugs located inside the lower cover. The two output conductive plates each include an output connector at one end and a rivet clamp at the other end. The output connector includes an arc-shaped spring piece that is pressed against each other. Each output connector is installed in the connector mounting base. The rivet clamp is riveted to the end of the DC output line. The middle of the output conductive plate is provided with an output connector hole, which is locked onto the protrusion. The input connector, the output connector, and the circuit board slot are arranged in a straight line. The circuit board is provided with an input conductive surface that is locked into the input connector and an output conductive surface that is locked into the output connector.

[0006] Furthermore, the input terminal conductive sheet is also provided with an input terminal snap-fit ​​hole in the middle, which is snapped onto the protrusion.

[0007] Furthermore, the input conductive sheet has a bent portion in the middle, and the lower cover has a matching stepped portion inside. The bent portion abuts against the stepped portion, and the input conductive sheet can be installed more securely in conjunction with the snap-fit ​​mounting base.

[0008] Furthermore, the card connector mounting base includes two semi-enclosed structures with opposite openings, which respectively abut against the outer side of the input card connector or the output card connector.

[0009] Furthermore, the upper cover has a slot inside for defining the position of the circuit board, which, together with the input end slot connector and the output end slot connector, defines the upper and lower positions of the circuit board, respectively.

[0010] The beneficial effects of this utility model are as follows: The power adapter of this utility model with solderless input and output terminals has protrusions and snap-fit ​​mounting bases inside the lower cover, which facilitates the installation of input and output conductive plates. The circuit board is designed with corresponding input and output conductive surfaces, thereby realizing a snap-fit ​​connection between the input and output terminals and the circuit board, replacing the existing soldering structure, ensuring the reliability of the electrical connection, improving product quality, and eliminating the need for soldering operations during the manufacturing process, thus speeding up the processing speed and improving production efficiency.
