[0002] In electronic components, pins are used to connect circuit boards, modules, or other electronic components. They are typically used to transmit signals, power, or data and play a crucial role in the assembly and maintenance of electronic equipment. The pins are usually made of copper alloys or gold-plated, silver-plated, or other materials to ensure good conductivity and corrosion resistance. The housing of the pins is usually made of plastic or ceramic materials to provide insulation protection and mechanical support.

[0003] When electronic components are connected using high-density pin mating, due to the presence of numerous pins, misalignment and poor contact can easily occur when the male and female terminals of the electronic components are plugged in, leading to a decrease in the contact reliability of the electronic components. To address this, we propose a high-density anti-misalignment pin assembly and an electronic component incorporating it. Utility Model Content

[0019] 1. This utility model includes a D-shaped guide pin, a plug ring, a positioning guide strip, a D-shaped socket, a plug ring groove, and a positioning guide slot. In use, the guide pin base is first aligned and inserted into the positioning guide slot in the plug ring groove of the socket base through the positioning guide strip on the plug ring, thereby achieving the insertion and positioning of the guide pin base and the socket base. Then, the guide pin is gradually inserted into the plug ring groove and the positioning guide slot through the plug ring and the positioning guide strip. During this process, the D-shaped guide pin will be aligned and inserted into the D-shaped socket until the guide pin base and the socket base are fully inserted.

[0036] This utility model includes a D-shaped guide pin 2, a plug ring 3, a positioning guide strip 4, a D-shaped plug hole 6, a plug ring groove 7, and a positioning guide slot 8. In use, the guide pin base 1 is first aligned and inserted into the positioning guide slot 8 in the plug ring groove 7 on the plug hole base 5 through the positioning guide strip 4 on the plug ring 3, thus achieving the insertion and positioning of the guide pin base 1 and the plug hole base 5. Then, the plug ring 3 and the positioning guide strip 4 are gradually inserted into the plug ring groove 7 and the positioning guide slot 8. During this process, the D-shaped guide pin 2 will be aligned and inserted into the D-shaped plug hole 6 until the guide pin base 1 and the plug hole base 5 are fully inserted. This enables the positioning and guiding insertion of the guide pin assembly. Only by aligning the positioning guide strip 4 and the positioning guide slot 8 can the insertion and positioning of the guide pin assembly be completed, avoiding the occurrence of misalignment problems and improving the insertion accuracy and positioning efficiency of the guide pin assembly.
