Description

Technical Field

[0001] The utility model relates to the field of circuit board terminals, in particular to a quick-insert terminal for connecting electronic components to a circuit board. Background Technique

[0002] The circuit board is a core component in modern electronic devices. The existing circuit board consists of a substrate, a printed circuit, and electronic components. All the electronic components on the existing circuit board are installed on the circuit board by welding. In the case of component damage, the circuit board needs to be removed first, and then the damaged electronic component can be removed by heating and melting the solder. Finally, the electronic component is soldered again. This is time-consuming and laborious. At the same time, when the circuit board is disassembled, it is easy to cause bumps or scratches on the circuit board due to improper operation, resulting in damage to the circuit board or other electronic components on the circuit board. Therefore, a circuit board that is convenient for replacing electronic components is needed. To achieve this technical goal, the connection between the component and the circuit board is realized through a quick replacement method. However, if the quick-insert module is directly soldered on the circuit board and the electronic component is inserted into the quick-insert module, in order to ensure the stable connection between the electronic component and the quick-insert module, the electrical connection between the electronic component and the quick-insert module needs to be ensured through a locking effect, resulting in inconvenient disassembly.
