Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connection spring, connector and electronic device. Background Technology

[0002] With the advancement of technology and economic development, electronic devices such as mobile phones and tablets have become indispensable daily necessities. These digital electronic products have been widely integrated into people's daily lives, providing great convenience for people's lives and work and enriching their lives. Springs are one of the essential components in electronic devices.

[0003] Each connector in an electronic device has several spring contacts, which are used to connect the circuitry or devices on both sides of the spring contacts. With the trend of miniaturization in electronic devices in recent years, the connectors inside the devices have also become smaller. The existing application of spring contacts is to place the spring contact connector on one side of the substrate, and the other substrate is provided with a contact surface that contacts the spring contact to achieve the purpose of crimp connection.

[0004] However, existing springs still have the following problems: existing springs occupy a large area of ​​the board, which is not conducive to the development trend of miniaturization design of electronic devices; existing springs have tilting displacement deformation, and the contact part will tilt as the compression stroke increases, which poses a risk of unstable contact. Utility Model Content
