Description

Technical Field

[0001] The utility model relates to an insertion pin for an electronic component, belonging to the technical field of insertion pins. Background Art

[0002] Electronic pins are widely used in various electronic components such as automotive connector terminals, various PCB circuit boards, computer connector terminals, etc. Its basic performance can be divided into three categories: mechanical performance, electrical performance and environmental performance. As for mechanical performance, plugging and pulling force is an important mechanical performance in terms of connection function. Plug-in force is divided into insertion force and extraction force, and the requirements for the two are different. From the perspective of use, the insertion force should be small, and if the extraction force is too small, it will affect the reliability of contact.

[0003] Patent No. CN201110229948.0 relates to an electronic component and its plug pins, wherein the electronic component includes a substrate, a plurality of electrode pads, a solder material and a plurality of plug pins. The electrode pads are formed on the substrate. The solder material is disposed above the plurality of electrode pads. The plug pins contact the solder material and are electrically connected to the plurality of electrode pads, wherein at least one plug pin includes a pin and a base. The base is disposed at a fixed end of the pin, wherein a plurality of openings are formed on the base and penetrate the base along an axial direction, and the axial direction is parallel to the pin. The present invention enables the air bubble cavities in the solder material in the reflow process to dissipate directly through the plurality of openings without pushing the base, thereby effectively preventing the plug pins from being skewed.

[0004] The above-mentioned pins are butt-jointed by a reflow process, but the disadvantage is that since the service life of the pins and the insertion and extraction force have an impact on each other, when the pins are damaged, the above-mentioned welding method cannot be quickly replaced. Therefore, we design a pin for electronic components. Utility Model Content
