Description

Technical Field

[0001] This utility model belongs to the field of electronic component technology, specifically relating to a pin assembly with an elastic contact structure and an electronic component. Background Technology

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

[0003] Existing pin assemblies mostly use rigid direct-insertion connections. When used in high-frequency vibration environments, rigid insertion can easily lead to poor contact, resulting in unstable pin connections of electronic components. This can easily lead to unstable transmission of electrical performance, affecting the connection stability and reliability of electronic devices. To address this, we propose a pin assembly and electronic component with an elastic contact structure. Utility Model Content

[0019] 1. In this utility model, the needle is elastically guided and set on the needle holder by the first elastic component and the second elastic component. When the needle assembly is inserted, the needle abuts against the insertion hole. At this time, the needle moves in the needle holder by the first elastic component and the second elastic component. The process is as follows: When the needle moves in the needle holder, the first spring and the second spring are compressed synchronously, so that the moving block is elastically guided to move in the guide limit post. At the same time, the needle moves elastically on the guide post, so that the first spring and the second spring are kept in a compressed state until the needle is fully inserted into the insertion hole. At this time, the needle and the needle holder are elastically connected. When the needle assembly is vibrated, the needle and the needle holder can also make elastic contact, thereby improving the stable connection between the needle assembly and the electronic device, avoiding the occurrence of poor contact, and improving the connection stability and reliability of the needle assembly.
