Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a terminal connection charging pin circuit charging structure. Background Technology

[0002] In current electronic product manufacturing processes, circuit boards and charging pins are typically connected by soldering. The circuit board consists of multiple layers of PCB, and the charging pins, generally made of copper, are responsible for power transmission. To ensure a stable electrical connection between the circuit board and the charging pins, a soldering iron is typically used to heat and melt the solder, then the charging pins are soldered to their corresponding positions on the circuit board. However, this traditional soldering method has several drawbacks in actual production.

[0003] During soldering, the high temperature of the soldering iron can easily cause deformation or decreased conductivity of the copper charging pins when the heat is conducted to them, affecting charging stability. Furthermore, the high temperature during soldering can also cause plastic parts to melt or deform, compromising waterproofing and increasing the risk of short circuits. In addition, overheating can lead to a loose connection between the charging pins and the circuit board, increasing the risk of detachment or poor contact, thus affecting the lifespan of the final product and the proper functioning of the charging process.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

The plug end 121 is located inside the charging slot 11, and the pin end 122 extends downward through the charging slot 11 and is electrically connected to the conductive terminal 30. In this embodiment, the conductive... Terminal 30 has a rectangular structure. The bottom surface of the conductive terminal 30 is electrically connected to the circuit board 20, and the top surface has a pin hole 31. The bottom wall of the charging slot 11 has a slot hole 111. The pin end 122 of the charging pin 12 passes through the slot hole 111 and is inserted into the pin hole 31. In this embodiment, the conductive terminal 30 has a conductive end piece (not shown in the figure). The conductive end piece has contacts on both sides. The two contacts are electrically connected to the circuit board 20 by soldering. The top surface of the conductive end piece has a contact piece that can penetrate into the pin hole 31.

Buttons 23 are electrically connected to both sides of the top surface of circuit board 20. The two buttons 23 pass through the button holes 131 and abut against the bottom of the buttons 141.

[0029] By setting up the light guide 40 and the light guide post 41, the light emitted by the multiple display lights 21 on the circuit board 20 can be effectively guided onto the panel 10, making the display effect more uniform and clearer. Furthermore, by setting up the locking post 42 and the locking post hole 22, the light guide 40 and the circuit board 20 can be easily assembled together, ensuring the simplicity and reliability of the assembly process.
